The measure of angle AVB = 131 degree .

A line with a starting point but extends upto infinity in one direction.

It is given that

Measure of angle AVF = 32

the measure of angle FVB = 2x + 9

the measure of angle AVB = 3x - 4

The angle AVB = AVF + FVB

this can be written as

3x- 4 = 2x+9 +32

x = 32+9+4

x = 45 degree

Therefore the measure of AVB = 3*45-4 = 131 degree

The value for I is 0.03, the value for n is 32, and the value of the periodic payment R is approximately $1,503.50

To solve this problem, let's break it down into the following components:

A) The value for I:

The interest rate per period (I) needs to be adjusted to match the compounding frequency. Since the interest is compounded quarterly, we need to divide the annual interest rate by the number of compounding periods per year.

I = Annual interest rate / Compounding periods per year

I = 12% / 4

I = 0.12 / 4

I = 0.03

B) The value for n:

The number of periods (n) is determined by the number of years multiplied by the number of compounding periods per year.

n = Number of years x Compounding periods per year

n = 8 years x 4

n = 32

C) The value of the periodic payment R:

We can use the formula for the future value of an ordinary annuity to find the periodic payment R:

S = R * [(1 + I)^n - 1] / I

50,000 = R * [(1 + 0.03)^32 - 1] / 0.03

50,000 = R * (1.03^32 - 1) / 0.03

50,000 = R * (1.999 - 1) / 0.03

50,000 = R * 0.999 / 0.03

R = 50,000 * 0.03 / 0.999

R = 1,503.50

Therefore, the value for I is 0.03, the value for n is 32, and the value of the periodic payment R is approximately $1,503.50.

Therefore, based on the analysis, the sample result of 110 grams is considered unusually low compared to the expected population mean of 118 grams.

To determine if the sample result of 110 grams is unusually low, we can use statistical analysis by comparing the sample mean to the population mean and considering the standard deviation.

Population mean (μ) = 118 grams

Standard deviation (σ) = 14 grams

Sample size (n) = 50

Sample mean (x) = 110 grams

First, we can calculate the standard error of the sample mean using the formula:

Standard Error (SE) = σ / √(n)

SE = 14 / √(50)

≈ 1.98 grams

Next, we can calculate the z-score, which measures the number of standard deviations the sample mean is away from the population mean. The formula for the z-score is:

z = (x - μ) / SE

z = (110 - 118) / 1.98

≈ -4.04

The z-score tells us how many standard deviations the sample mean is below the population mean. In this case, the z-score is approximately -4.04. To determine if the sample result is unusually low, we need to compare the z-score to a critical value. Typically, a z-score beyond a certain threshold (usually 2 or -2) is considered unusual. Using a threshold of 2 standard deviations, if the z-score falls beyond -2, it would indicate that the sample mean is unusually low. In this case, the z-score of -4.04 is significantly below -2, which suggests that the sample mean of 110 grams is indeed unusually low.

Let's find

You are exactly halfway to the top of the ferris wheel at 72 seconds, and you are 28 feet above the ground at that point.

1. Calculate the circumference of the ferris wheel:

  Circumference = π * diameter

  Circumference = π * 60 ft ≈ 188.5 ft

2. Determine the time it takes for the ferris wheel to make half a rotation:

  Half rotation time = 48 seconds / 2 = 24 seconds

3. Calculate the distance traveled by the ferris wheel in 24 seconds:

  Distance = (Circumference / time) * distance traveled in 24 seconds

  Distance = (188.5 ft / 48 s) * 24 s ≈ 94.25 ft

4. Find the height at which you are halfway to the top of the ferris wheel:

  Height halfway = distance traveled - height from the ground

  Height halfway = 94.25 ft - 8 ft = 86.25 ft

5. Determine the time it takes for you to reach the halfway point:

  Time to halfway = 24 seconds + 48 seconds = 72 seconds

6. Calculate the height at the halfway point:

  Height at halfway = Height halfway + height from the ground

  Height at halfway = 86.25 ft + 8 ft = 94.25 ft

Therefore, you are exactly halfway to the top of the ferris wheel at 72 seconds, and you are 94.25 ft above the ground at that point.

Option A is the correct answer. Ellora wants to accumulate 150,000 in an RRSP by making annual contributions of 5,000 at the beginning of each year. If interest is 5.5% compounded quarterly, calculate how long she has to make contributions.

First, we have to find the interest rate per quarter, which will be
\(5.5% / 4\)= 1.375%.
The formula for the future value of an annuity is: 
\(FV = (C * [(1 + r)^n - 1] / r)\),

For Ellora, \(FV = $150,000, C = $5,000, and r = 1.375%.\)
Substituting these values into the formula gives:
\(150,000 = 5,000 * [(1 + 0.01375)^n - 1] / 0.01375\)
Simplifying this equation gives:
\(30 = [(1.01375)^n - 1]\)

We can solve this using logarithms:
\(ln 30 = ln [(1.01375)^n - 1]\)
\(ln 30 = n * ln 1.01375 - ln 1.01375e^(ln 30) / e^(-ln 1.01375) = n18.202125 = n\)

Therefore, it will take Ellora 18.202125 years to accumulate 150,000 in her RRSP through \($5,000\)annual contributions made at the beginning of each year with interest of \(5.5%\) compounded quarterly.

Step-by-step explanation:

The complete question is

James has a board that is 3/4 foot long. He wants to cut the board into pieces that are each 1/8 foot long. How many pieces can James cut from the board?

Solution

Given,

The total length of the board is equal to \(\frac{3}{4}\) feet

Total number of pieces to made = X

Size of each piece that is cut from the board is \(\frac{1}{8}\) feet long

Total number of pieces that can be cut from the board is equal to total size of board divided by size of each sub part

\(X = \frac{\frac{3}{4} }{\frac{1}{8} } \\X = \frac{3}{4} * \frac{8}{1} \\X = 3 * 2 \\X = 6\)

Hence, 6 pieces can be cut out of the board

The population of interest to the department of education will be all college students.

A population is a large group of individuals that have some common feature by the researcher's point of interest.

Here the Department of Education wishes to estimate the proportion of all college students who have a job off-campus.

Proportion: A proportion is an equation in which two ratios are set equal to each other. If there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4).

So , he needs data of all students to compute the exact proportion.

But instead of that he surveyed 1600 randomly selected students which determine the sample.

Sample just gives the estimate of the parameter.

Hence, the population of interest to the Department of education is " All college students" .

The formula for calculating the required sample size to estimate the population mean with a 90% confidence level is given by:

n = ((z_(α/2)×σ) / E)²Here, z_(α/2) is the z-value for the given level of confidence (90% in this case), σ is the population standard deviation (6.8 in this case), and E is the maximum error we can tolerate (0.02 in this case).

Substituting the given values in the formula, we get:

n = ((z_(α/2)×σ) / E)²n = ((1.645×6.8) / 0.02)²n = 1910.96

Rounding up to the nearest whole number, we get the required sample size to be 1911.

Therefore, a sample size of 1911 is required to estimate the population mean with a 90% confidence level and an error of less than 0.02.
