Answer:

7606.62

Step-by-step explanation:

Start by finding how much you will have through the annuity. The question isn't that clear, so i will just assume it's an annuity due.

\(p(\frac{(1+i)^n-1}{i})*(1+i)\\i=.035/12= .0029166667\\n=10*12=120\\p=75 (given)\\75\frac{(1+.0029166667)^{120}-1}{.0029166667}*(1+.0029166667)= 10788.814149\\\)

Now just equate this to a time 0 payment at the same rate

\(10788.814149=(1+.0029166667)^{120}*x\\x= 7606.6228603=7606.62\)

As a quick note, if you were supposed to assume that your annuity was an annuity immediate the answer would be 7584.50.

i didnt quite understand what you were asking but here is it broken down. :)

Normal model for sizes is (7,1)

Here 5% of female customer have foot size in between 6-10

a)We were told that there are dress shoes in sizes 6 to 10 point, and the tailor believes that, with the exception of 5% of his female customers, the shoe would fit almost everyone. As a result, it accounts for 95 percent of female customers or women who try on his shoes, and we've been asked to determine what standard model for sizes is consistent.

b)The mean is 8 and the standard deviation is 2 points. So, we can say that x follows a normal model with a mean of 8 and a variance of 4 point right and in part b, we were asked whether a retailer should order more shoes in sizes 4 and 5 or more shoes in sizes 11 and 12 point so the best way to do this is to draw a balk curve or the symmetric table. So let's try to graft that together. draw it out to begin with so an important feature of the normal curve of the ball curves that it's always symmetric about the mean.

Answer:

  about 1.1%

Step-by-step explanation:

Given a moon has a diameter of 22% of the diameter its planet, you want the volume of the moon as a percent of the planet's volume.

The ratio of moon diameter to planet diameter is given as 22%. The ratio of moon volume to planet volume will be the cube of this scale factor:

  moon volume / planet volume = (0.22)³ ≈ 0.0106 = 1.06%

The volume of the moon is about 1.1% of the volume of the planet.

To evaluate the expression (2b+3a)×(c^2) when a=4, b=3, and c=1/3, we substitute the given values into the expression and perform the indicated arithmetic operations:

(2b + 3a) × (c^2)

= (2(3) + 3(4)) × ((1/3)^2) (substitute a=4, b=3, c=1/3)

= (6 + 12) × (1/9) (evaluate 2(3) + 3(4) and (1/3)^2)

= 18/9

= 2

Therefore, when a=4, b=3, and c=1/3, the expression (2b+3a)×(c^2) equals 2.

Answer:

18

Step-by-step explanation:

From the triangle inequality we know that the sum of any two sides must be larger than the third side. We us the inequality here.

The third side must be greater than 17 and smaller than 19. So the smallest possible (and the only possible) whole-number length for c is 18

Using long division for the integration, the final answer is (1/3)x³ + x² + 3x + 5 ln |x³ - x² + x - 1| + C, where C is the constant of integration.

To integrate the given expression using long division, we need to divide the numerator, 3x³ + 1, by the denominator, x³ - x² + x - 1, to obtain a quotient that we can integrate.

First, let's perform the long division:

   x² + 2x + 3

------------------

x³ - x² + x - 1 | 3x³ + 0x² + 0x + 1

   3x³ - 3x² + 3x - 3

   ------------------

          3x² + 2x - 2

          3x² - 3x + 3

          -----------

                  5x - 5

Therefore, we can rewrite the original integral as:

∫[(3x³ + 1) / (x³ - x² + x - 1)] dx = ∫[x² + 2x + 3 + (5x - 5) / (x³ - x² + x - 1)] dx

The first term, x² + 2x + 3, can be integrated easily. For the second term, we can use partial fraction decomposition or substitute u = x³ - x² + x - 1 to obtain:

∫[(5x - 5) / (x³ - x² + x - 1)] dx = 5∫[du / u] = 5 ln |u| + C

= 5 ln |x³ - x² + x - 1| + C

Putting everything together, we get:

∫[(3x³ + 1) / (x³ - x² + x - 1)] dx = ∫[x² + 2x + 3 + (5x - 5) / (x³ - x² + x - 1)] dx

= ∫[x² + 2x + 3] dx + 5 ln |x³ - x² + x - 1| + C

= (1/3)x³ + x² + 3x + 5 ln |x³ - x² + x - 1| + C

Answer :SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)

Step 1: Isolate the absolute value expression.

Step2: Set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.

Step 3: Solve for the unknown in both equations.

Step 4: Check your answer analytically or graphically.

Step-by-step explanation:

Answer:

x can equal 5 or -5 since absolute value changes everything into a positive number.

Step-by-step explanation:

Keep in mind that without the population standard deviation, it is impossible to provide an exact sample size. However, this formula will give you a good starting point.

To find the sample size needed for a 99.5% confidence interval with a margin of error of 1.5, we can use the formula:

n = (Z * σ / E)^2

where n is the sample size, Z is the Z-score corresponding to the desired confidence level, σ is the population standard deviation, and E is the margin of error.

For a 99.5% confidence interval, the Z-score is approximately 2.807 (from a standard normal distribution table). Since we do not have the population standard deviation (σ), we will need to estimate it using a sample standard deviation or use a conservative approach by assuming the maximum possible value. For now, let's assume we have an estimated standard deviation.

n = (2.807 * σ / 1.5)^2

Solve for n by plugging in the estimated standard deviation (σ) and then round up to the nearest whole number, as you cannot have a fraction of a sample.

Answer:

Let the length of the rectangle be L. Then we can use the formula for the area of a rectangle:

Area = Length x Width

Substituting the given values, we get:

16 1/3 = L x 4 2/3

To solve for L, we can first convert the mixed numbers to improper fractions:

16 1/3 = 49/3

4 2/3 = 14/3

Substituting these values, we get:

49/3 = L x 14/3

To solve for L, we can multiply both sides by the reciprocal of 14/3:

49/3 ÷ 14/3 = L

Simplifying, we get:

L = 49/3 x 3/14

L = 7/1

L = 7

Therefore, the length of the rectangle is 7 inches.

Step-by-step explanation:

this means

the square root of 64 is 8.

The distance between points P and Q is √73

First, remember that the distance between two points whose coordinates are (a, b) and (c, d) is given by:

distance = √( (a - c)² + (b - d)²)

Here we can see that the coordinates of the two shown points are:

P = (-3, 2)

Q = (5, -1)

Replacing that in the distance formula we will get:

distance = √( (-3 - 5)² + (2 + 1)²)

distance = √( (-8)² + (3)²)

distance = √73

Answer:

\(b = 5 \sqrt{3} \ or\ b = -5 \sqrt{3}\)

Step-by-step explanation:

Given

\(f(b) = b^2 - 75\)

Required

Determine the roots

To get the root of the function, then f(b) must be 0;

i.e. f(b) = 0

So, the expression becomes

\(0 = b^2 - 75\)

Add 75 to both sides

\(75 + 0 = b^2 - 75 + 75\)

\(75 = b^2\)

Take square roots of both sides

\(\sqrt{75} = \sqrt{b^2}\)

\(\sqrt{75} = b\)

Reorder

\(b = \sqrt{75}\)

Expand 75 as a product of 25 and 3

\(b = \sqrt{25*3}\)

Split the expression

\(b = \sqrt{25} *\sqrt{3}\)

\(b = \±5 *\sqrt{3}\)

\(b = \±5 \sqrt{3}\)

\(b = 5 \sqrt{3} \ or\ b = -5 \sqrt{3}\)

The options are not clear enough; however the roots of the equation are \(b = 5 \sqrt{3} \ or\ b = -5 \sqrt{3}\)
