Answer:
381.7 mm cubed
Step-by-step explanation:
To find the volume of a sphere is V=4 /3πr³
----------
Since they give you the diameter, you have to divide by 2, so:
9 ÷ 2 = 4.5
When you plug in 4.5, you get you answer.

Please help im confused on the last question on my warm up!
Answer:
Choice B: Only (-1,-5)
Step-by-step explanation:
With this one, first the equation needs to be reduced into point-slope format.
y+5=2(x+1)
Distributive Prop.
y+5=2x+2
Carry over the 5 to the opposite side.
y=2x-3
Now, with the point slope form, it makes it easier to plug in the question choices to find which if any are correct.
Choice A: X is 5; Y is 10
y=2x-3
y=2(5)-3
y=10-3
y=7
This does not give a y value of 10, so it is false.
Choice B: X is -1; Y is -5
y=2(x)-3
y=2(-1)-3
y= -2-3
y= -5
This does give a y value of -5, so it is true. Choices C and D are therefore false as well, since only Choice B works.
How do you divide fractions?

I'm about to share an image with you that explains how to divide fractions!!
Answer:
KCF (Keep Change Flip) 3/4 divided by 2/3. Keep 3/4 change the division sign to mulitplication and flip the 2 and the 3 to an improper fraction of 3/2 and then solve. Just remember KCF and you'll be good. I used to be trash at fractions and now I'm very good thanks to KCF.

A new test is developed to test for a certain allergy, giving "positive" or "negative" results to indicate that a person does or does not have the allergy. For a person who has the allergy, the test will give a positive result 82% of the time and a negative result (false negative) 18% of the time. For a person who does not have the allergy, the test will give a positive result (false positive) 10% of the time and a negative result 90% of the time. A study included a population of 10,000 people, and 1% of those studied where known to have the allergy. Fill in the missing values in the table below, and complete the statements that follow. Round the percentage to the nearest tenth, if necessary.

Step-by-step explanation:
The volume of a sphere is given by [tex]4\pi r^3[/tex]. Since a radius is half a diameter, the radius of the sphere is [tex]\frac{16.6}{2}=8.3[/tex].
Substituting values, we have:

e) The diagonal of square A, marked off by the red stars, is where the concession stand is located. A local high school band is performing at the outdoor theater on a summer evening. The band has a school banner that is 40-feet long, and band members would like to hang it across the concession stand to let people know they are performing. Estimate the length of the concession stand to determine if the school banner can fit across the length of the concession stand. Show your work and explain your reasoning.
Answer:
60 ft long bc that would leave 10ft on each side of the banner...Step-by-step explanation:
Hopes this helps. Mark as brainlest plz!Answer:
Solution given:
length [l]=breadth [b]=40ft
Now
length of concession banner[h]=?
we have
perpendicular [p]=base[B]=40ft
by using Pythagoras law
h²=p²+b²
h²=40²+40²
h=√3200
h=40√2
So
the length of the concession stand to determine if the school banner can fit across the length of the concession stand is 40√2 ft or 56.57ft
NEED HELP ASAP TAKING TEST A refrigeration unit at a restaurant is supposed to be kept at 40°F. An inspector would like to test the hypotheses H Subscript 0 Baseline: mu = 40 versus H Subscript alpha Baseline: mu not-equals40 where μ = the true mean temperature for all times of the day. A 98% confidence interval based upon a random sample of 40 temperatures is 40.5 degrees to 42.1 degrees. Using the interval, what decision should be made?
The null hypothesis should be rejected at the Alpha = 0.01 level.
The null hypothesis should be rejected at the Alpha = 0.02 level.
The null hypothesis should not be rejected at the Alpha = 0.05 level.
The null hypothesis should not be rejected at the Alpha = 0.10 level.
Answer:
,, the null hypothesis should be rejected at the alpha equals 0.02 level
Suppose that among all U.S. Students, 80% have gone to an amusement park and 45% have gone to a beach. Only 15% have done neither. If you select a student at random, what is the probability that the student has gone to the beach but not to an amusement park
Answer:
5%
Step-by-step explanation:
Let x represent the percentage of people that have gone to both the park and the beach.
The percentage of people that have gone only to the amusement park = 80% - x% = 80 - x
The percentage of people that have gone only to the beach = 45% - x% = 45 - x
Therefore:
100% = (80 - x) + (45 - x) + (x) + (15)
100 = 80 + 45 + 15 -x - x + x
100 = 140 - x
x = 140 - 100
x = 40%
Therefore 40% of the students have gone to both the park and the beach.
The probability that the student has gone to the beach but not to an amusement park = 45% - 40% = 5%
Jordan wants to split up his socks and shoes into groups. If he has 6 pairs of shoes and 14 pairs of socks, how many groups must he create so he has an equal number of pairs of shoes and pairs of socks?
Answer:
i amm not sure
Step-by-step explanation:
The number of groups Jordan must create so he has an equal number of pairs of shoes and pairs of socks is 2.
What is HCF?The highest common factor (HCF) is discovered by identifying all common factors of two integers and then picking the greatest one. For example, the common factors of 8 and 12 are 1, 2, and 4. The greatest common factor is four.
Jordan wants to split up his socks and shoes into groups. If he has 6 pairs of shoes and 14 pairs of socks. Therefore, she can divide the pair of socks and shoes only into groups of 2, because two is the HCF of 6 and 14.
Hence, the number of groups Jordan must create so he has an equal number of pairs of shoes and pairs of socks is 2.

Clay surveys members of his class to find out how many televisions they have in their homes. The thirteen responses he received are shown in the table. Which statement is true?
A) The mean is less than the mode.
B) The mean is less than the range.
C) The mean is greater than the range.
D) The median is greater than the mode.
Answer:
B, the mean is less than the range
Step-by-step explanation:
mean is 3.38 (rounded)
mode is 3
median is 3
range is 5
The mean is 3.38 and the range is 5, So the mean is less than the range. Option B is the correct one.
What are mean?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
Mean = [tex]\frac{1+5+2+3+4+6+3+1+3+4+3+5+4}{13}[/tex]
The mean is 3.38 (rounded)
Median represents the middle value of the given data when arranged in a particular order.
So, the Median would be 3.
Mode is that number that appears most frequently in the given set of data.
So, the Mode would be 3.
The range of a given set of data is the difference between the largest value and the smallest value.
So, the range would be 5

A study by the department of education of a certain state was trying to determine the
mean SAT scores of the graduating high school seniors. The study found that the
mean SAT score was 447 with a margin of error of 21. Write a confidence interval for
the true mean SAT score of the graduating high school seniors.
Answer:
(426 ; 468)
Step-by-step explanation:
Confidence interval :
Mean score ± margin of error
Margin of Error = 21
Mean SAT score = 447
Hence,
447 ± 21
Lower boundary = 447 - 21 = 426
Upper boundary = 447 + 21 = 468
