Answers
Answer:
126.99 cm³
Step-by-step explanation:
volume of cone = ⅓πr²h ≅ 296.88 cm³
volume of empty portion = 296.88 - 169.89 = 126.99 cm³

Grocery Store A is selling bananas for $0.75 for 12 pound. Grocery Store B is selling 5 pounds of bananas for $3.75.
Which store is offering the best unit rate? Show your work
Answers
Answer:
12 ×$0.75 =$8.00
3.75 ÷ 5 = $1.33 a pound,
$1.33 × 12 = $15.96 so store A is offering the best rate.
It is found that Store B is offering the best unit rate for the bananas.
What is unit rate?There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.
Given that Grocery Store A is selling bananas 1/2 pound for $0.75 .
Grocery Store B is selling 5 pounds of bananas for $3.75.
According to the question,
Store A is selling bananas 1/2 pound for $0.75 .
Therefore,
For one pound will be;
= 0.75/0.5
= 1.5
And store B is selling 5 pounds of bananas for; $3.75
Therefore,
One pound will cost;
3.75/ 5 = 0.75
Hence, Store B is offering the best unit rate for the bananas.

A and B are complementary angles. If m_A= (2x + 10)° and m
ZB = (3x + 15)°, then find the measure of ZB
Answers
Step-by-step explanation:
<A + < B = 90° { being complementary angles)
2x + 10° + 3x + 15° = 90°
5x = 90° - 15° - 10°
5x = 65°
x = 13°
Now
<B = 3x + 15° = 3 *13° + 15° = 54°

Use elimination to solve the system
2x-y=10

Please someone help I need help so bad I’m so scared I’m gonna fail this test I may get held back if I fail this test please help me
Answers
2x + 8x - y + y = 10 + 20
Combine like terms:
10x = 30
Divide by 10:
x = 3
Plug x back in to solve for y:
2(3) - y = 10
6 - y = 10
Subtract 6:
-y = 4
Divide by -1:
y = -4
So your solution is x = 3 and y = -4 which is also written as (3, -4).
Identify at least one confounding variable that undermines the conclusion drawn in the following fictional study:
Prof. Acosta was interested in which of two popular statistics textbooks (Statistics: It Will Change Your Life and Statistics: Bigger, Better, Stronger) was better for students. Prof. Acosta compared the two texts by assigning one text to a section of statistics taught by Prof. Agnew from 10 to 11 a.m. on Monday, Wednesday, and Friday, and the other text to a section of statistics taught by Prof. Alvarez from 7 to 10 p.m. on Wednesday evenings. At the end of the term, all students took the same comprehensive test. Students to whom Statistics: Bigger, Better, Stronger was assigned performed better on the test than did students to whom Statistics: It Will Change Your Life was assigned. Therefore, Prof. Acosta concluded that the former textbook was the better one.

Answer:
Identifying at least one confounding variable that undermines the conclusion drawn in the fictional study is:
All students took the same comprehensive test.
Step-by-step explanation:
In a study, an independent variable causes an effect on the dependent variable. But a confounding variable is the variable that influences the independent variable as well as the dependent variable. If this third variable is not controlled, it might lead the researcher to make a wrong estimate of the relationship that exists between the independent variable and the dependent variable.

Ten students from a class participated in a math quiz. The scores obtained by
them were recorded as follows.
11, 6, 7, 13, 1, 13, 16, 7, 13, 16
Mean :
Median :
Mode :
Range :
Answers
Answer:
Mean: 10.3
Median: 12
Mode: 13
Range: 15
Step-by-step explanation:
First, let's define what all these terms mean.
Mean is the average of all the numbers in a set of data. Median is the number in the middle of a range whenever the numbers are put in ascending order. If there are two numbers in the middle instead of one, then take the average of those two numbers. Mode is the number that occurs the most in the set of data. Range is the difference between the largest and the smallest number in a set of data.
To make things a little easier overall, let's just go ahead and put all our numbers in ascending order, which will be as follows: 1, 6, 7, 7, 11, 13, 13, 13, 16, 16.
To find the mean, just add up all the numbers and divide by how many there are. So we'll add 1 + 6 + 7 + 7... and so on to get a total of 103. Next, we'll divide that number by 10 since there are 10 students. This gives us a mean of 10.3.
Next, we'll find the median. To find this, just figure out which number(s) is in the center of your data. Since we have an even number of terms (10), we'll have two numbers in the middle, being 11 and 13. To find our median from here, just add 11 and 13 and then divide by 2. 11 + 13 = 24 and then 24 / 2 = 12. This means that our median is 12.
Next, we'll find the mode. The mode is the number that is seen the most in a set of numbers. In our set, we see that there are three 13s. Since 13 is the most frequently used number in our set, this makes it the mode.
Finally, we'll find the range. The range is just the largest number in the set minus the smallest number in the set. In our set, 16 is our largest number and 1 is our smallest. Just do 16 - 1 = 15 and we'll see that 15 is the range of the set. Hope this helps!
