If a sum of two real numbers is less than 50, then at least one of the number is less than 25.
Prove by contraposition.

Answers

Answer 1

Answer:

So basically you will switch the predicate and proposition (p implies q) and we will negate it so not q implies not p. So we will say that both x and y should be 25 or greater and that the sum will be 50 or greater. Below you will find the steps. I just took this course and got a 96% so i think u should get near to full points on something along the lines of this answer. The only thing u may have to change is that we should probably use k and j for x and y but off the top of my head i cannot recall exactly how to word that. Then prove using k and j but the logic is exactly the same. Its just how proofs work. Substitute in a variables for variables ..

Step-by-step explanation:

Proof by contraposition : Let x and y be real numbers. Assume x is a real number greater than or equal to 25 and y is greater than or equal to 25 and the sum of x and y is greater than or equal to 50. We can then take the minimum 25 and 25 and the sum of this gives 50. This satisfies our minimum requirement of 50 since any other number combination will be above 50 we have proven by contraposition that for the sum of two real numbers x and y one number must be less than 25 to be create a sum less than 50

Therefore, the total amount of glass used to make the five visible faces of the aquarium is:

600 + 360 + 240 = 1200 square inches.

What is a rectangle made of?

2-D enclosed shapes with four sides, four corners, and four right angles are called rectangles. A rectangle has two equal and parallel opposite sides. A rectangle is a two-dimensional shape with length and width as its dimensions.

The aquarium has six faces, but since one of the faces will be the bottom of the aquarium and won't be visible, we only need to find the total amount of glass used to make the remaining five faces.

The aquarium has two identical faces, which are the front and back faces. Each of these faces has dimensions of 20 inches by 15 inches. So the total area of these two faces is:

2 x (20 x 15) = 600 square inches

The aquarium also has two identical faces, which are the left and right faces. Each of these faces has dimensions of 12 inches by 15 inches. So the total area of these two faces is:

2 x (12 x 15) = 360 square inches

Finally, the aquarium has one top face, which has dimensions of 20 inches by 12 inches. So the area of this face is:

20 x 12 = 240 square inches

Therefore, the total amount of glass used to make the five visible faces of the aquarium is:

600 + 360 + 240 = 1200 square inches.

we draw a random sample of size 36 from the normal population with variance 2.1. if the sample mean is 20.5, what is a 95% confidence interval for the population mean?

Answers

The 95% confidence interval for the population mean is approximately [20.03, 20.97].

What is confidence interval?

The percentage (frequency) of acceptable confidence intervals that include the actual value of the unknown parameter is represented by the confidence level.

To calculate the 95% confidence interval for the population mean based on a sample of size 36 with a known variance of 2.1 and a sample mean of 20.5, we can use the formula for a confidence interval for a population mean:

CI = \(\bar X\) ± z * (σ / √n),

where:

CI is the confidence interval,

\(\bar X\) is the sample mean,

z is the z-score corresponding to the desired level of confidence (in this case, 95% confidence),

σ is the population standard deviation,

n is the sample size.

Since we have the population variance (2.1), we can calculate the population standard deviation as σ = √2.1 ≈ 1.45.

Now, let's calculate the confidence interval:

CI = 20.5 ± z * (1.45 / √36).

The z-score corresponding to a 95% confidence level is approximately 1.96 (you can look this up in a standard normal distribution table or use a statistical software).

Substituting the values:

CI = 20.5 ± 1.96 * (1.45 / √36).

Calculating the values within the confidence interval:

CI = 20.5 ± 1.96 * 0.2417.

CI = 20.5 ± 0.4741.

Finally, we can calculate the lower and upper bounds of the confidence interval:

Lower bound = 20.5 - 0.4741 ≈ 20.03.

Upper bound = 20.5 + 0.4741 ≈ 20.97.

Therefore, the 95% confidence interval for the population mean is approximately [20.03, 20.97].

i choose a random integer n between $1 and $10 inclusive what is the probability that for the n i chose there exist no real solutions to the equation x x 5 n express your answer as a common fraction

Answers

The probability that for a randomly chosen integer n between 1 and 10 inclusive there exist no real solutions to the equation x^2 + 5 = n is 3/10.

we can first find the values of n for which there are real solutions to the equation x^2 + 5 = n. We can do this by rearranging the equation to get x^2 = n - 5 and then seeing that there are real solutions only if n - 5 is non-negative, i.e. n >= 5.

Since we are choosing a random integer between 1 and 10 inclusive, there are 10 possible values for n. Out of these, only 5, 6, 7, 8, 9, and 10 are greater than or equal to 5, which means that there are real solutions to the equation for these values of n. Therefore, there are only 6 possible values of n for which there exist no real solutions to the equation.

Therefore, the probability of choosing one of these 6 values of n is 6/10, which simplifies to 3/5. However, we need to find the probability of choosing one of the values of n for which there exist no real solutions to the equation, which is the complement of the probability of choosing one of the values of n for which there are real solutions. This complement is 1 - 6/10, which simplifies to 2/5.

Therefore, the main answer to the question is that the probability that for a randomly chosen integer n between 1 and 10 inclusive there exist no real solutions to the equation x^2 + 5 = n is 2/5.

The probability that for a randomly chosen integer n between 1 and 10 inclusive there exist no real solutions to the equation x^2 + 5 = n is 2/5. This can be found by first determining the values of n for which there are real solutions to the equation, and then finding the complement of this probability.

The range of the logarithm function y = log5x consists of all real numbers. The logarithm function is defined for positive real numbers, and as x approaches 0 from the positive side, the logarithm approaches negative infinity. As x increases, the logarithm function approaches positive infinity.

The range of the function is the set of all possible output values. In this case, the range consists of all real numbers that can be obtained by evaluating the logarithm

log5(�)log 5 (x) for �>0 x>0.

Since the base of the logarithm is 5, the function log5x will take on all real values from negative infinity to positive infinity. Therefore, the range of the function f(x) = log5x is (-∞, +∞).

Answers

Answer: 5\(\sqrt{3}\)

Step-by-step explanation:

The 30-60-90 triangle rule states that the hypotenuse is twice the length of the shortest leg (which would be 5) and the longer leg is \(\sqrt{3}\) times the length of the shorter leg.

Since we are trying to find x we would use the rule for the longer leg

so 5 * \(\sqrt{3}\) would just be 5\(\sqrt{3}\)

The value of the x is 5√3 after we successfully do the application of the 30°-60°-90° Triangle theorem.

What is Triangle theorem?

The 30°-60°-90° Triangle Theorem states that in such a triangle, the side opposite the 30° angle is half the length of the hypotenuse, and the side opposite the 60° angle is the product of the length of the hypotenuse and the square root of 3 divided by 2.

here, we have,

Using this theorem, we can write:

y = hypotenuse

Opposite of 30° angle = 5 = hypotenuse/2

Opposite of 60° angle = x = hypotenuse × (√(3)/2)

Solving for the hypotenuse in terms of y from the first equation, we get:

hypotenuse = 5×2 = 10

Substituting this value into the third equation, we get:

x = 10 × (√(3)/2) = 5 × √(3)

Hence, The value of the x is 5√3 after we successfully do the application of the 30°-60°-90° Triangle theorem.

The amount of undeveloped land in a suburban community has been decreasing by one-eighth each year since 2002. In 2002, there were 30 acres of undeveloped land

find the solution showing the number of years, t, it took for the amount of undeveloped land to be approximately 15.39 acres.

Answers

It took approximately 5.3 years for the amount of undeveloped land to decrease to approximately 15.39 acres, starting from 30 acres in 2002.

Let L(t) be the amount of undeveloped land in acres at time t, where t is measured in years since 2002. Then, we can write:

L(t) = 30 * (7/8)^t

We know that the amount of undeveloped land we are interested in is approximately 15.39 acres. Therefore, we can set up the following equation:

15.39 = 30 * (7/8)^t

To solve for t, we can first divide both sides by 30:

0.513 = (7/8)^t

Next, we can take the natural logarithm of both sides:

ln(0.513) = ln[(7/8)^t]

ln(0.513) = t * ln(7/8)

t = ln(0.513) / ln(7/8)

t ≈ 5.3

Therefore, it took approximately 5.3 years for the amount of undeveloped land to decrease to approximately 15.39 acres, starting from 30 acres in 2002.

what is the approximate average rate at which the area decreases, as the rectangle's length goes from 13\text{ cm}13 cm13, start text, space, c, m, end text to 16\text{ cm}16 cm16, start text, space, c, m, end text?

Answers

The approximate average rate at which the area decreases as the rectangle's length goes from 13 cm to 16 cm is equal to the width (w) of the rectangle.

To determine the approximate average rate at which the area decreases as the rectangle's length goes from 13 cm to 16 cm, we need to calculate the change in area and divide it by the change in length.

Let's denote the length of the rectangle as L (in cm) and the corresponding area as A (in square cm).

Given that the initial length is 13 cm and the final length is 16 cm, we can calculate the change in length as follows:

Change in length = Final length - Initial length

= 16 cm - 13 cm

= 3 cm

Now, let's consider the formula for the area of a rectangle:

A = Length × Width

Since we are interested in the rate at which the area decreases, we can consider the width as a constant. Let's assume the width is w cm.

The initial area (A1) when the length is 13 cm is:

A1 = 13 cm × w

Similarly, the final area (A2) when the length is 16 cm is:

A2 = 16 cm × w

The change in area can be calculated as:

Change in area = A2 - A1

= (16 cm × w) - (13 cm × w)

= 3 cm × w

Finally, to find the approximate average rate at which the area decreases, we divide the change in area by the change in length:

Average rate of area decrease = Change in area / Change in length

= (3 cm × w) / 3 cm

= w

Therefore, the approximate average rate at which the area decreases as the rectangle's length goes from 13 cm to 16 cm is equal to the width (w) of the rectangle.

What percent of his gross pay is take-home pay?
31.5%
44.8%
46%
68.5%

Answers

68.5% of Colton's gross pay is take-home pay. To find the percentage of Colton's gross pay that is take-home pay, we need to divide his net pay by his gross pay and then multiply by 100 to convert the resulting decimal to a percentage.

To find the percentage of Colton's gross pay that is take-home pay, we need to divide his net pay by his gross pay and multiply the resulting decimal by 100 to express it as a percentage. Colton's gross pay is $1421.50 and his net pay is $973.48. Dividing the net pay by the gross pay gives a result of 0.685, or 68.5% when converted to a percentage. This means that 68.5% of Colton's gross pay is take-home pay, or the amount of money that he receives after deductions are made. Therefore, Colton's take-home pay is $973.48, which is 68.5% of his gross pay.
