In mathematics, we can define ratio as how many times one number contains another. In the other word, a ratio says how much of one thing there is compared to another thing. Example, there are ten apples and six lemons in a basket of fruit, then the ratio of apples to lemons is ten to six (10:6). We can also say that the ratio of apples to the total amount of fruit is 10:16.

Ratios making us easier to understand the case by allow us to measure and express quantities.

Case:

- a box holds 20 marbles

-  13 green marbles

-  7 yellow marbles (20-13=7)

What is the ratio of yellow marbles to green marbles?

The null hypothesis (H0) states that the mean GPA of night students is equal to 2.4, while the alternative hypothesis (H1) suggests that the mean GPA is greater than 2.4. These hypotheses are based on the claim made by Fayech University regarding the normal distribution of the mean GPA with a mean of 2.4 and a population standard deviation of 0.02. A significance level of 0.01 is chosen for the hypothesis test.

In hypothesis testing, the null hypothesis represents the assumption or claim being tested, while the alternative hypothesis represents the alternative claim. In this case, H0 states that the mean GPA of night students is equal to 2.4. On the other hand, H1 suggests that the mean GPA is larger than 2.4, indicating a claim contrary to H0. To test these hypotheses, a sample of 45 people is used, with a sample mean GPA of 2.44. The next step would involve performing a hypothesis test, typically using a statistical test such as a t-test or z-test. However, since the population standard deviation is known, a z-test can be conducted. Using the sample mean, population mean, population standard deviation, and sample size, the z-score can be calculated. The z-score represents the number of standard deviations the sample mean is away from the population mean. By comparing the calculated z-score to the critical value associated with the chosen significance level (0.01), a decision can be made to either reject or fail to reject the null hypothesis. Please note that the specific calculations and decision-making process for this hypothesis test require additional information beyond what has been provided.

Answer:

Step-by-step explanation:

Assuming the -1 is not a typo, we can see that the function h is a linear function. Thus we can simply plug in -1 and 1 for h, then take the average of the 2 values we get.

h(-1) = 26, and h(1) = 8.

Average = (26 + 8)/ 2 = 17

The problem asks to find the average value of h on the interval [-1,1]. To do this, use the formula avg = 1/(b-a)∫[a,b] h(x)dx, where a and b are the endpoints of the interval. The integral can be evaluated from -1 to 1, resulting in an average value of approximately 0.0611.

The problem is asking us to find the average value of the function h on the given interval. The function is h(u) = (18 − 9u)−1 and the interval is [−1, 1].

To find the average value of the function h on the given interval, we can use the following formula: avg = 1/(b-a)∫[a,b] h(x)dx where a and b are the endpoints of the interval. In this case, a = -1 and b = 1, so we have:

avg =\(1/(1-(-1)) ∫[-1,1] (18 - 9u)^-1 du\)

Now we need to evaluate the integral. We can use u-substitution with u = 18 - 9u and du = -1/9 du:∫(18 - 9u)^-1 du= -1/9 ln|18 - 9u|We evaluate this from -1 to 1:

avg = \(1/2 ∫[-1,1] (18 - 9u)^-1 du\)

= \(1/2 (-1/9 ln|18 - 9u|)|-1^1\)

= 1/2 ((-1/9 ln|9|) - (-1/9 ln|27|))

= 1/2 ((-1/9 ln(9)) - (-1/9 ln(27)))

= 1/2 ((-1/9 * 2.1972) - (-1/9 * 3.2958))

= 1/2 ((-0.2441) - (-0.3662))

= 1/2 (0.1221)

= 0.0611

Therefore, the average value of the function h on the interval [-1,1] is approximately 0.0611.

Answer:

265.42

Step-by-step explanation:

The total Chikp paid for the stock was:

(75 shares)*($19.58/share) = $1468.50

--

At the end of the year his stock was worth (75 shares)*($22.14/share) = $1660.50

The is a net gain of ($1660.50 - $1468.50) = $192

Add the dividend income to arrive at his total profit for the year:

$192 + $73.42 = $265.42

Naya's gross annual income is approximately $46,416.67.

To determine Naya's gross annual income, we need to reverse engineer the tax calculation based on the given information.

Let's denote Naya's gross annual income as G. We know that Naya's net annual income, after income tax, is 36,560. We also know that Naya pays income tax at the same rates and has the same annual tax credits as Emma.

Emma pays income tax on her taxable income at a rate of 20% on the first 35,300 and 40% on the balance. She has annual tax credits of 1,650.

Based on this information, we can set up the following equation:

G - (0.2 * 35,300) - (0.4 * (G - 35,300)) = 36,560 - 1,650

Let's solve this equation step by step:

G - 7,060 - 0.4G + 14,120 = 34,910

Combining like terms, we have:

0.6G + 7,060 = 34,910

Subtracting 7,060 from both sides:

0.6G = 27,850

Dividing both sides by 0.6:

G = 27,850 / 0.6

G ≈ 46,416.67

Therefore, Naya's gross annual income is approximately $46,416.67.

Social scientists gather data from samples instead of populations because c. populations are often too large to test.

Social scientists often cannot test an entire population due to its size, so they gather data from a smaller group or sample that is representative of the larger population. This allows them to make inferences about the larger population based on the data collected from the sample. The sample size must be large enough to accurately represent the population, but it is not necessarily larger or more complete than the population itself. Trustworthiness, meaning, and interest are subjective and do not necessarily determine why social scientists choose to gather data from samples.

The solutions to the system of congruences are all integers of the form x ≡ 2969 + 330k, where k is an integer.

To find all solutions to the system of congruences:

x ≡ 1 (mod 2)

x ≡ 2 (mod 3)

x ≡ 3 (mod 5)

x ≡ 4 (mod 11)

We begin by finding the product of all the moduli, M = 2 * 3 * 5 * 11 = 330. Then, for each congruence, we find the values of mi and Mi such that miMi ≡ 1 (mod mi), where Mi = M/mi.

For the first congruence, we have m1 = 2 and M1 = 165, and since 165 ≡ 1 (mod 2), we have m1M1 ≡ 1 (mod m1). Similarly, for the second congruence, we have m2 = 3 and M2 = 110, and since 110 ≡ 1 (mod 3), we have m2M2 ≡ 1 (mod m2). For the third congruence, we have m3 = 5 and M3 = 66, and since 66 ≡ 1 (mod 5), we have m3M3 ≡ 1 (mod m3). Finally, for the fourth congruence, we have m4 = 11 and M4 = 30, and since 30 ≡ 1 (mod 11), we have m4M4 ≡ 1 (mod m4).

Next, we compute the values of x1, x2, x3, and x4, which are the remainders when Mi xi ≡ 1 (mod mi) for each congruence.

For the first congruence, we have M1 x1 ≡ 1 (mod m1), which implies that 165 x1 ≡ 1 (mod 2), or equivalently, 1 x1 ≡ 1 (mod 2). Therefore, x1 = 1. Similarly, we find that x2 = 2, x3 = 3, and x4 = 4.

Finally, we compute the solution x by taking the sum of aiMi xi for each congruence. That is, x = 1 * 165 * 1 + 2 * 110 * 2 + 3 * 66 * 3 + 4 * 30 * 4 = 2969. Therefore, 2969 is a solution to the system of congruences.

To find all solutions, we add M to 2969 successively, since adding M to any solution gives another solution, until we find all solutions that are less than M. Thus, the solutions are:

x ≡ 2969 (mod 330)

x ≡ 329 (mod 330)

x ≡ 659 (mod 330)

x ≡ 989 (mod 330)

x ≡ 1319 (mod 330)

x ≡ 1649 (mod 330)

x ≡ 1979 (mod 330)

x ≡ 2309 (mod 330)

x ≡ 2639 (mod 330)

x ≡ 2969 (mod 330)

So, the solutions to the system of congruences are all integers of the form x ≡ 2969 + 330k, where k is an integer.

Answer:

m= 3

Step-by-step explanation:

In the slope-intercept form (y= mx +c), the coefficient of x (when the coefficient of y is 1) is the slope.

y= x +5

Slope of line= 1

Parallel lines have the same slope, hence the slope of 3y -mx +3= 0 is also equal to 1.

Let's rewrite the equation into slope-intercept form.

Keep the y term on the left-hand side, bring the others to the right.

3y= mx -3

Divide both sides by 3:

\(y = \frac{m}{3} x - 1\)

Given that the slope is 1,

\( \frac{m}{3} = 1\)

Multiply both sides by 3:

m= 1(3)

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A small plastic vessel has the shape of a truncated cone as shown. A cubic centimeter is the same as a milliliter.

Then the volume of this cup to the nearest milliliter will be

The volume is given as

\(\rm V = \dfrac{1}{3} \pi (r_2^2 - r_1^2) h\)

We have

Height (h) = 10 cm = 0.1 m

Radius (r₁) = 3.2 cm = 0.032 m

Radius (r₂) = 2.4 cm = 0.024 m

Then the volume will be

\(\rm V = \dfrac{1}{3} \pi (0.032^2 - 0.024^2) \times 0.1\\\\\rm V = 4.7 \times 10^{-5} \ \ m^3\)
