A certain college randomly selected 30 freshman students who completed college algebra during their first semester. Fifteen students were chosen from students who took the course at night and 15 students were chosen from students who took the course during the day. The following statistical information was calculated from their final grades.
Day Night
Mean 76 68
Median 68 72
Mode 64 72
Range 38 53
Based on these samples, what generalization can be made? (Assume that a score of 70 or greater is a passing score.)
A.
The mean score for the night students was higher than the mean score for the day students.
B.
The median score for the day students was higher than the median score for the night students.
C.
The mean score for the day students was higher than the mean score for the night students.
D.
The range of scores was larger for the day students than for the night students.
It's C because if you look at the day and night students, the mean score for the day students was actually higher then the mean score for the night student.

Gabriele built a composite figure using 12 cubes for the bottom layer and 10 cubes for the top layer.she said that the volume of the composite figure was 12 times 10 or 120 cubic centimeters find and correct her error
The volume of a composite figure is not simply the product of the number of cubes in each layer. To find the volume of the composite figure, we need to find the volume of each layer separately and then add them together.
Explanation:The volume of a composite figure is not simply the product of the number of cubes in each layer. To find the volume of the composite figure, we need to find the volume of each layer separately and then add them together.
Let's start by finding the volume of the bottom layer. Since there are 12 cubes and each cube has a volume of 1 cubic centimeter, the volume of the bottom layer is 12 cubic centimeters.Next, let's find the volume of the top layer. Since there are 10 cubes and each cube has a volume of 1 cubic centimeter, the volume of the top layer is 10 cubic centimeters.Finally, we can add the volumes of the bottom and top layers together to find the total volume of the composite figure. 12 cubic centimeters + 10 cubic centimeters = 22 cubic centimeters.Therefore, the correct volume of the composite figure is 22 cubic centimeters, not 120 cubic centimeters.
list 3 values that would make this inequality true 42 ≤ 24 + y
18, 19, 20 are the three values that would make this inequality true 42 ≤ 24 + y
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is 42 ≤ 24 + y
Forty two lesser than or equal to twenty four plus y.
We need to find any three value which would make the inequality true.
We have to take the values of y which are added with 24 must be greater than or equal to twenty four.
Suppose let us take 18 as y
42≤ 24 + 18
42≤ 42 which is true
We have to take values greater than 18 which makes the inequality as true
42≤ 24 + 19
42≤ 43 true
42≤ 24 + 20
42≤ 44 true
Hence, 18, 19, 20 are the three values that would make this inequality true 42 ≤ 24 + y

solve the equation of 4 (3q-2)=16q
The solution of expression for value of q is,
⇒ q = - 2
We have to given that,
An equation to simplify,
⇒ 4 (3q - 2) = 16q
Now, We can solve the expression for q as,
⇒ 4 (3q - 2) = 16q
Divide both side by 4;
⇒ 4 (3q - 2) /4 = 16q / 4
⇒ (3q - 2) = 4q
Subtract 3q both side,
⇒ 3q - 2 - 3q = 4q - 3q
⇒ - 2 = q
⇒ q = - 2
Therefore, The solution is,
⇒ q = - 2

What are the coordinates of the midpoint of the line segment with endpoints
B(9, −8) and C(2, −5)? Enter your answer as a decimal or integer in the boxes.
( , )
( (9 + 2 ) / 2 , ( -8 + -5 ) / 2 ) =
( 11/2 , -13/2 )
Answer:
The mid-point of the given line segment is:(5.5,-6.5)
Step-by-step explanation:
let us consider two points A and B with coordinates (a,b) and (c,d) respectively.
let C be the mid point of A and B then then the coordinates of C is given by [tex](\frac{a+c}{2},\frac{b+d}{2})[/tex].
in the given question (a,b)=(9,-8) and (c,d)=(2,-5) so the mid point of these two points are [tex](\frac{9+2}{2},\frac{-8-5}{2})[/tex]=(5.5,-6.5)
Hence, the coordinates of the midpoint of the line segment with endpoints B(9,-8) and C(2,-5) is (5.5,-6.5).

Staci is attending a music festival. The ticket to the festival costs $87.96. Staci plans to purchase $30.00 t-shirt from the event for close friends. she is taking $200.00 to the festival. what is the maximum number of t-shirts can purchase?
After purchasing the festival ticket, Staci has $112.04 remaining from her $200 budget. Each T-shirt costs $30, so she can buy a maximum of 3 T-shirts.
Explanation:The student asked how many
T-shirts Staci can purchase at a music festival considering she has a budget of $200, and she also needs to buy a ticket and possibly T-shirts for her friends.
First, we need to subtract the cost of the festival ticket from Staci's total budget which is $200.00 - $87.96 = $112.04 remaining. Now, if each T-shirt costs $30.00, we can find the maximum number of T-shirts she can purchase by dividing the remaining money by the cost of one T-shirt.
$112.04 / $30.00 = 3.734.
Since Staci cannot buy a fraction of a T-shirt, she can purchase a maximum of 3 T-shirts with the remaining budget.

Dave has a life insurance policy with $2.2 million benefit. If this money was put into an account with a 3.4% interest rate, how much income can his beneficiaries expect i case Dave dies?
A $74, 800
B $20, 600
C. $60, 000
D $40, 000
Answer:
Step-by-step explanation:
The maximum value can reach $74, 800 if Dave Dies.
What is Exponential GrowthInsofar as they use compound interest, life insurance premiums are equivalent to bank interest rates. We may use the exponential growth formula to get the insurance policy payout because they are compound interests. Those being the following,
Given:
T = [tex]a(1+r)^t[/tex]
Where:
T is the final payout, a is the initial amount, r is the interest rate in decimal form and t is the time.
So, T = [tex]2200000(1+ 0.034)^t[/tex]
let Dave dies after 2 years of buying his life insurance the beneficiaries will get the following payout.
T = [tex]2200000(1+ 0.034)^2[/tex]
T= 2200000 ( 1.069156)
T = $23,52,143.2
So, the maximum value can reach $74, 800.

A circle has a center at (1,-2) and radius of 4. Does the point (3.4,1.2) lie on the circle? Justify your answer.
The point (3.4, 1.2) lies on the circle with center at (1, -2) and radius of 4, as the distance from the point to the circle's center is exactly equal to the circle's radius.
The question asks if the point (3.4, 1.2) lies on a circle with a center at (1, -2) and a radius of 4. To determine this, we can use the distance formula, which calculates the distance between two points in a coordinate plane. The distance formula is √((x_2 - x_1)^2 + (y_2 - y_1)^2), where (x_1, y_1) and (x_2, y_2) are the coordinates of the two points. In this case, the center of the circle is (1, -2) and the point in question is (3.4, 1.2).
To see if the point lies on the circle, we check if the distance from the point to the center equals the circle's radius. Calculating: √((3.4 - 1)^2 + (1.2 - (-2))^2) = √((2.4)^2 + (3.2)^2) = √(5.76 + 10.24) = √16 = 4. Since this distance is exactly 4, which is the circle's radius, the point (3.4, 1.2) does indeed lie on the circle.

Michael has 225 milliliters of a liquid. To find out the number of grams of calcium in this liquid, Michael multiplies the volume by 0.015. When he writes the number representing the amount of calcium in the liquid, how many significant digits will the number have?
Answer:the answer is 2 trust me it had 2 significant digits
Step-by-step explanation:
The reason why is because the number 0.015 only has 2 significant digits is because until a number that is not 0 comes up then it doesn’t count as a significant digit so in this case the number 1 is the number that does start with a zero so thats 1 significant digit and then after that is 5 so they’re is the second significant digit so the 2 other zeros don’t count cause in order for the zero to be a significant digit it has to be to the left of a other number thats not 0 so there’s your answer mark me brailiest pls and have a good day .-. :)
