Ms.Alvarez's math class surveyed 10 students in 6th grade and 10 students in 7th grade. The class asked how many hours of chores each student did the previous weekend. The results were displayed in two histograms.
Mean is greater for grade 7.
Median is greater for grade 7.
So, the correct options are B and D.
What is mean and median?"The mean is the number you get by dividing the sum of a set of values by the number of values in the set.
The median is the middle number in a set of values when those values are arranged from smallest to largest."
Mean for grade 6 is
= [tex]\frac{1+2+3+1+1+1+1}{7}[/tex]
= [tex]\frac{10}{7}[/tex]
Mean for grade 7 is
= [tex]\frac{1+2+5+2}{4}[/tex]
= [tex]\frac{10}{4}[/tex]
From both we get, Mean is greater for grade 7
Median for grade 6 is 1
Median for grade 7 is
= [tex]\frac{2+5}{2}[/tex]
= 3.5
From both we get, Median is greater for grade 7
So, the correct options are B and D.

Brady recorded the number and color of cars in the parking lot. 45% of the cars in the parking lot were white. If Brady counted a total of 81 white cars, how many cars did he count in the parking lot?
Answer:
180 cars
Step-by-step explanation:
Like you can see in the picture, I like to set up a proportion, so 81 over X and 45 over 100. Then, you can cross multiply, so 81 x 100 = 8100 and then divide, 8100 ÷ 45 = 180, your answer!

A furniture store offers free setup and delivery services to all points within a 25-mile radius of its warehouse distribution center. If you live 20 miles east and 14 miles south of the warehouse, will you incur a delivery charge? JUSTIFY YOUR ANSWER!
Answer:
Step-by-step explanation:
make a good drawing and notice the right triangle with legs 20 mi and 14 mi
the distance from home to the warehouse is the hypotenuse c of the right triangle thus we will use the Pythagorean Theorem:
c^2 = 20^2 + 14^2
c^2 = 596
c = 24.41 mi approximately is the distance from home to a warehouse
since 24.41 < 25 you will incur a delivery charge.
Answer:
no, delivery charges will not be incurred

Answer:
W = 8.2 cm
Step-by-step explanation:
The perimeter formula is P = 2W + 2L and here the perimeter is 65.6 cm.
Thus, 65.6 cm = 2W + 2L. Substituting 3W for L, we get
65.6 cm = 2W + 2(3W) = 8W.
Solving for W by dividing both sides by 8, we get W = 65.6 cm / 8, or
W = 8.2 cm

2) 240cm
Step-by-step explanation:
Question 1:
[tex]A=(4x+1)^{2}[/tex]
[tex]P = 4(4x+1) = 16x+4[/tex]
[tex]16(2)+4 = 36ft[/tex]
[tex]Perimeter = 36ft[/tex]

The model below represents an equation. Write the equation that is modeled then find what value of x makes the equation true. HELP ASAP PLZ PLZ PLZ PLZ
Answer:
x = 5
Step-by-step explanation:
6x - 5 = 4x + 5
The only thing that makes x true is 5. (This might not help if I read the question wrong.)
Answer:
6x-5=4x+5
x=5
Step-by-step explanation:
6x-5=4x+5
Subtract 6x from both sides
-5=-2x+5
Subtract 5 from both sides
-10=-2x
Divide by -2 on both sides
x=5
