"in the table below, Identify the figure,find it's perimeter, and find it's area.". <- that's the question
Answer:
✔️Quarter circle
✔️Area = 38.5 cm² (nearest tenth)
✔️Perimeter = 25.0 cm (nearest tenth)
Step-by-step explanation:
✔️The figure given is a ¼ circle
Radius is given as = 7 cm
✔️Area = ¼(πr²)
Plug in the value of r
Area = ¼(π*7²)
Area = ¼(π*49)
Area = 38.5 cm² (nearest tenth)
✔️Perimeter = ¼(2πr) + 2r
Plug in the value of r
Perimeter = ¼(2*π*7) + 2(7)
Perimeter = ¼(14π) + 14
Perimeter = 25.0 cm (nearest tenth)

FRQ 2
At a particular coffee shop, 92% of customers order a beverage, 3% of customers order food alone (order food and not a beverage), and 12% of customers order food and a beverage. Suppose we randomly select a customer. Let B = the customer orders a beverage and F = the customer orders food.
a) What is P(F)? Interpret this value in context.
b) What is the probability that the customer orders food given that they order a beverage? Write this event in symbolic form and find the probability.
c) If 180 customers are randomly selected, how many of them can we expect to order neither food nor a beverage? Justify your response.
Answer:
a) P(F) = 0.15
b) P(F/B) = 0.13
c) 5% customers order neither food not beverage.
Further explanation is in the explanation section
Step-by-step explanation:
Solution:
Data given:
B = The customer orders a beverage
F = The customer orders food.
F + B = The customers order food and a beverage.
Percentage share:
F = 3%
B = 92%
F + B = 12%
a)
So, the Probability of B, the customer orders a beverage will be:
P(B) = 92% = 0.92
Probability of (F+B), the customers orders food and beverage will be:
P(F ∩ B) = 12% = 0.12
And we know that, 3% customers order food alone so,
P(F) - P(F ∩ B) = 3% = 0.03
So,
P(F) = (P(F) - P(F ∩ B)) + P(F ∩ B)
P(F) = 0.03 + 0.12
P(F) = 0.15
It means that 15% customer order food only.
b) Probability that the customer orders food given that they order a beverage.
P(F/B) = (Probability that the customer orders food given that they order a beverage.)
P(F/B) = P(F∩B)/P(B)
P(F/B) = 0.12/0.92 = 0.13
P(F/B) = 0.13
Symbolic form of the required probability is = P(F/B)
c) If 180 customers are randomly selected, how many of them can we expect to order neither food nor a beverage?
Probability of ordering food and beverage will be:
P(F U B)
So,
Probability of ordering neither food nor beverage will be = 1 - P(F U B)
And,
P(F U B) = P(F) + P(B) - P(F ∩B)
P(FUB) = 0.15 + 0.92 - 0.12
P(FUB) = 0.95
Probability of ordering neither food nor beverage will be = 1 - P(F U B)
Probability of ordering neither food nor beverage will be = 1 - 0.95
Probability of ordering neither food nor beverage will be = 0.05
Hence, 5% customers order neither food not beverage.
So, we have selected 180 random people so, 5% of 180 =
number of people order neither food nor beverage = 5/100 x 180
number of people order neither food nor beverage = 9 people
It means we can expect out of 180 people, 9 people will not order food or beverage.

Choose the answer that shows 5–15 rewritten using a positive exponent.
Answer:
The required answer is [tex]\dfrac{1}{5^{15}}[/tex].
Step-by-step explanation:
Consider the provided exponent.
The given exponent is [tex]5^{-15}[/tex].
We need to write it using a positive exponent.
So, use the property: [tex]a^{-m}=\dfrac{1}{a^m}[/tex]
By using the above property we can rewrite the given exponent as:
[tex]5^{-15}=\dfrac{1}{5^{15}}[/tex]
Hence, the required answer is [tex]\dfrac{1}{5^{15}}[/tex].
A track coach is gathering data on the stride length of each of her 52 team members when running a distance of 500 meters. The population mean is 62.95 inches with a standard deviation of 5.65 inches.
What is the standard error of the sample mean? Round your answer to the nearest hundredth.
The standard error of the sample mean is approximately ______.
Answer:
The standard error of the sample mean (S.E) = 0.7835
Step-by-step explanation:
Explanation:-
Given mean of the Population = 62.95 inches
Given standard deviation of the Population = 5.65 inches
The standard error of the sample mean is determined by
[tex]S.E = \frac{S.D}{\sqrt{n} }[/tex]
[tex]S.E = \frac{5.65}{\sqrt{52} } = 0.7835[/tex]
The standard error of the sample mean is approximately (S.E) = 0.7835.
What is the standard error?It is an estimate of the standard deviation of the sampling distribution. It measures the variability of a considered sample statistic.
Supopse that we're given that:
Population standard deviation =[tex]\sigma[/tex]
Size of sample we're working on = n
Then, the standard error can be calculated as:
[tex]SE = \dfrac{\sigma}{\sqrt{n}}[/tex]
where SE denotes the standard error.
A track coach is gathering data on the stride length of each of her 52 team members when running a distance of 500 meters.
The population means is 62.95 inches with a standard deviation of 5.65 inches.
The mean of the Population = 62.95 inches
The standard deviation of the Population = 5.65 inches
The standard error of the sample mean can be determined by
[tex]= \dfrac{Standard deviation }{\sqrt{sample size}}\\\\\\= \dfrac{5.65 }{\sqrt{52}}\\= 0.7835140[/tex]

The ratio of boys to girls in Ms. Reedus's classroom is 2 to 3. There are 18 girls in the classroom. What is the total number of students in Ms. Reedus's class?
Answer: The final answer is 30.
Step-by-step explanation: The question says the ratio is 2 boys : 3 girls. There are 18 girls. Well, how did you get from 3 to 18? You multiply by 6. But whatever you do to the denominator you have to do with the numerator. So, multiply 2 and 6. That gives you 12 boys and 18 girls. Adding 12 and 18 gives you 30. Therefore, there are 30 students in the whole class.

Answer: A
Step-by-step explanation:
In this equation, the largest exponent is odd, so the two ends are going in different directions. Since the leading coefficient is positive, the left side is going down, while the right side is going up.
As y approaches negative infinity (goes down), x approaches negative infinity (goes left).
Simplified: as the y value decreases, the x value decreases.
As y approaches infinity (goes up), x approaches infinity (goes right).
Simplified: as the y value increases, the x value increases.
