The circle with radius r units is divided into congruent sectors to create the shape shown below.
For estimation purposes, the shape formed by the sectors is considered to be a parallelogram. Which statement is true?
Answer:
A
Step-by-step explanation:
Just took the test
The statement that asserts a true claim would be:
A). The height is approximately r units and the base length is approximately πr units.
What is the sector?The sector is described as an element of the circle or a part that extends to the center.
In the given figure, the height of the congruent sectors would be equivalent to r units as the radius is r units.
While the length of its base would be equivalent to πr units to denote the base length.
Thus, option A is the correct answer.

A circular clock with a circumference of 88cm is mounted on a wall.How much area of a wall didn't occupy
Answer:
616 cm^2
Step-by-step explanation:
Steps to derive the answer
1. we are going to first determine the radius from the circumference
2. we would calculate the area
Circumference of a circle = 2nr
n = 22/7
r = radius
88 = 2 x 22/7 x r
Divide both sides of the equation by 2 x 7/22
r = 14
Area of a circle = nr^2
3.14 x 14^2 = 616 cm^2
Why correlation does not prove causation ?
Answer:
here you go
Step-by-step explanation:
"Correlation is not causation" means that just because two things correlate does not necessarily mean that one causes the other. ... Correlations between two things can be caused by a third factor that affects both of them. This sneaky, hidden third wheel is called a confounder
Why does correlation not equal causation example?
It does not tell us why and how behind the relationship but it just says the relationship exists. Example: Correlation between Ice cream sales and sunglasses sold. As the sales of ice creams is increasing so do the sales of sunglasses. Causation takes a step further than correlation.
m∠A+ m∠B = ? How do you know this?
Answer:
Step-by-step explanation:
If m∠A + m∠B = m∠B + m∠C, subtract m∠B from both sides [ subtraction property of equality ].
We get that m∠A = m∠C and by the symmetric property of equality, m∠C = m∠A

Scores on the GRE (Graduate Record Examination) are normally distributed with a mean of 573 and a standard deviation of 84. Use the 68-95-99.7 Rule to find the percentage of people taking the test who score between 489 and 573
The percentage of people taking the test who score between 489 and 573 is
Answer:
The percentage of people taking the test who score between 489 and 573 is 34%.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 573, standard deviation of 84
Percentage of people taking the test who score between 489 and 573
The mean is 573.
489 = 573 - 84, which means that 489 is one standard deviation below the mean.
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are below the mean.
So between one standard deviation below the mean and the mean, the percentage is 68/2 = 34%
The percentage of people taking the test who score between 489 and 573 is 34%.

Answer:
∠ BAC = 28.5°
Step-by-step explanation:
∠ AOB = 180° - 57° = 123° ( straight angle )
OA and OB are congruent ( radii of the circle ) , then Δ AOB is isosceles with base angles congruent, that is
∠ BAC = ∠ ABO , then
∠ BAC = [tex]\frac{180-123}{2}[/tex] = [tex]\frac{57}{2}[/tex] = 28.5°
4) You randomly select one card from a 52-card deck. Find the probability of selecting the 6 of hearts or the ace of diamonds.
Answer:
1/26
Step-by-step explanation:
There is only one 6 of hearts and only one ace of diamonds.
The probability of selecting the 6 of hearts is thus 1/52, and that of selecting the ace of diamonds is also 1/52.
The probability of selecting the 6 of hearts or the ace of diamonds is the SUM of these two results: 1/52 + 1/52 = 2/52 = 1/26.

A family buys 4 airline tickets online. The family buys travel insurance that costs $16 per ticket. The
total cost is $680. Let x represent the price of one ticket. Write an equation for the total cost. Then find
the price of one ticket.
Which equation represents this situation?
O A. 680 = 4(x + 16)
OB. 680 = 4x + 16
OC. 16 = 4x + 680
OD. 680 = 16(x + 4)
The price of one ticket is $1.
!NEEDED ASAP!
Answer:
B
x is representing the price of one ticket in which the tickets bought was four.so therefore (x+x+x+x+16)=680
4x + 16 =680
The Student Monitor surveys 1200 undergraduates from 100 colleges semiannually to understand trends among college students. Recently, the Student Monitor reported that the average amount of time spent per week on the Internet was 19.0 hours. You suspect that this amount is far too small for your campus and plan a survey. You feel that a reasonable estimate of the standard deviation is 10.0 hours. What sample size is needed so that the expected margin of error of your estimate is not larger than one hour for 95% confidence
Answer:
A sample size of 385 is needed.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
You feel that a reasonable estimate of the standard deviation is 10.0 hours.
This means that [tex]\sigma = 10[/tex]
What sample size is needed so that the expected margin of error of your estimate is not larger than one hour for 95% confidence?
A sample size of n is needed. n is found when M = 1. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]1 = 1.96\frac{10}{\sqrt{n}}[/tex]
[tex]\sqrt{n} = 1.96*10[/tex]
[tex](\sqrt{n})^2 = (1.96*10)^2[/tex]
[tex]n = 384.16[/tex]
Rounding up:
A sample size of 385 is needed.
