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.
Answers
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.

Answer:
1152 ft^2
Step-by-step explanation:
There are 7 faces on this solid.
I will label the faces and will calculate each area with an explanation.
Faces 1 and 2:
The front face and the back face are congruent and have 5 sides each. Each face is a rectangle with a triangle above it. The lower rectangular part has dimensions 9 ft by 12 ft. The triangle above the rectangle has base 9 ft and height 16 ft - 12 ft = 4 ft.
Each face is a rectangle and a triangle.
area = area of rectangle + area of triangle
area = LW + bh/2
area = 9 ft * 12 ft + 9 ft * 4 ft/2 = 108 ft^2 + 18 ft^2 = 126 ft^2
This is area of of face 1, the front face. Face 2, the rear face has the same area.
A1 = 126 ft^2
A2 = 126 ft^2
Face 3: The bottom of the solid is a rectangle measuring 9 ft by 20 ft
area = LW
area = 9 ft * 20 ft = 180 ft^2
A3 = 180 ft^2
Faces 4 and 5:
The left vertical face and the right vertical face are congruent rectangles measuring 12 ft by 20 ft.
area = LW
area = 12 ft * 20 ft = 240 ft^2
A4 = 240 ft^2
A5 = 240 ft^2
Faces 6 and 7 are the top right and left inclined rectangles. They are congruent, and each one has dimensions 6 ft by 20 ft.
area = LW
area = 6 ft * 20 ft = 120 ft^2
We need 2 of these area.
A6 = 120 ft^2
A7 = 120 ft^2
total surface area = A1 + A2 + A3 + A4 + A5 + A6 + A7
total surface area = 126 ft^2 + 126 ft^2 + 180 ft^2 + 240 ft^2 + 240 ft^2 + 120 ft^2 + 120 ft^2
total surface area = 1152 ft^2

UGH! RSM!!!!!!!!!!!!!!!!!!!!! John's family visited his grandmother over the weekend. The drive to her house took 2 hours at their usual speed. the trip home took 15 minutes longer because traffic was bad and they had to drive 5 mph slower. How many miles away is john's grandmother's house? will give BRAINLIEST! +10pts!
Answers
Hope this helps!
Answer:
90 miles!
Step-by-step explanation:
there are two parts to the problem, meaning you'll need 2 equations.
let's call the distance TO the grandma's house d1, and BACK from the grandma's house d2.
KEY:
time TO g'ma house= t1
time FROM g'ma house=t2
(replace the t's with 's' for speed, with the '1' for to, and '2' for from)
(distance is a constant so d1 is always equal to d2).
-------------
d1=s1+t1, d2=s2+t2
we know what t1 is. 2 hours.
d1=s1•2
meaning that d2 is also equal to that.
s1•2=(s1-5)•2 1/4
2s1=2 1/4 s1-11 1/4
11 1/4= 2 1/4 s1-2s1
11 1/4 = 1/4 s1
s1 (to g'ma)=45 mph
distance is speed times time.
so 45•2 (hr) = 90.

Step-by-step explanation:
this is me
The independent variable is found to be d.
What is an independent variable?An independent variable can be defined as a variable that can take any value which implies it is not dependent on any other variables.
The example can be given as y = x + 2, here x is an independent variable.
The given algebraic expression w = 7d + 13
There are two terms 7d and 13.
Here, the variable term is 7d.
And, the value of w depends on d which implies that d is the independent variable.
Hence, in the given expression the independent variable is d.
