The correct answer would be:
B. The number of pages in each book varied more last summer than this summer.
Step-by-step explanation:
I was doing my test and this was the correct answer. Sorry if this is too late for you.! I hope you have a great day.
The inference that can be drawn from the data is the number of pages in each book varied more last summer than this summer.
How to measure variance in data?Range can be used to measure variance in a data set. Range is the difference between the largest number and the smallest number. The larger the difference, the greater the variance.
Range= largest number - smallest number
Range of pages read this summer = 180 - 150 = 30
Range of pages read last summer =220 - 140 = 80

6 MATH CHALLENG Mr. Jacob's class has silent reading for twenty minutes every day after lunch recess. Mrs. Clark's class has silent reading on Monday, Wednesday and Friday for half an hour. In four weeks, how many more minutes will the students in Mr. Jacob's class spend reading than the students in Mrs Clark's class?
Answer:
200
Step-by-step explanation:
Mr. Jacob's class reads every day for 20 minutes, which ends up being 20 * 28 because there are 28 days in four weeks. That equals 560
Mrs. Clark's class reads 3 days a week for 4 weeks, so 3*4 = 12. The number of minutes her class reads is 30 minutes so 30*12 = 360.
560-360=200

The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)
Answer:
94.86 miles per hour
Step-by-step explanation:
The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)
The appropriate customary unit is calculated as:
1 km = 0.62 miles
153 km = x
Cross Multiply
x = 153 × 0.62 miles
94.86 miles
Therefore, the appropriate customary unit is 94.86 miles per hour

six less than the sum of a number and seven is twice the difference of the same number and 12
Answer:
D
Step-by-step explanation:
(x + 7) - 6 = 2 (x - 12)
Equation : (x+7) - 6 = 2(x-12) represents most accurately reflects the given statement.
What is Simplification ?Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter), for example
Simplification of algebraic expressions, in computer algebra.
Let the number be x.
Sum of a number and seven = x+7
Difference of number and twelve = x-12
According to question,
(x+7) - 6 = 2(x-12)
Thus, the equation : (x+7) - 6 = 2(x-12) represents most accurately reflects the given statement.

An iron ball has a density of 4 g/cm3.
The volume of the ball is 15 cm3.
What is the mass of the ball?
========================================================
Explanation:
m = mass
v = volume
d = density
The formula we use is
d = m/v
Multiplying both sides by v allows us to solve for m
d = m/v
d*v = m
m = d*v
Now plug in the given density (d = 4) and the given volume (v = 15) and simplify:
m = d*v
m = 4*15
m = 60 grams
Note how,
d = m/v
d = 60/15
d = 4

Joseph's uncle wants to put shingles on the outside walls and solar panel the roof of his barn shown at the right. It costs $2.50 for each square meter of shingles, while solar panals cost $4.00 per square meter. How much will this project cost?
Answer:
The answer is below
Step-by-step explanation:
From the image attached, the measurement of the roof is 5 m by 9 m on both sides. Hence:
Area of roof = 2 (5 * 9) = 90 m²
Since solar panels cost $4.00 per square meter, therefore:
Cost of solar panels = $4.00 per square meter * 90 m² = $360
The area of the front wall of the barn = (8 m * 7 m) + (1/2 * 8 m * 3 m) - (4 m * 4 m) = 52 m²
The area of the back wall of the barn = (8 m * 7 m) + (1/2 * 8 m * 3 m) = 68 m²
Area of each side wall of barn = 9 m * 7 m = 63 m²
Total area of wall = 52 m² + 68 m² + (2 * 63 m²) = 246 m²
Cost of shingles = $2.50 for each square meter * 246 m² = $615
Total cost of project = $615 + $360 = $975

Whats the area of the rectangle?
Length: 2 1/7
width: 3 1/3
I dont need an explanation just the simplified answer
Answer:
The area of rectangle is "31 units²".
Step-by-step explanation:
The given values are:
Length of rectangle,
= [tex]\frac{21}{7}[/tex]
Width of rectangle,
= [tex]\frac{31}{3}[/tex]
As we know,
The area of rectangle is:
= [tex]Length\times width[/tex]
On substituting the values, we get
= [tex]\frac{21}{7}\times \frac{31}{3}[/tex]
= [tex]\frac{217}{7}[/tex]
= [tex]31 \ units^2[/tex]

A park has a triangular sandbox. Todd wants to create a smaller sandbox at his backyard having the same angles as the park sandbox. Drawings of both sandboxes are shown. 18 ft 20 Park Sandbox 8+ Todd's Sandbox What is the perimeter, in feet (ft), of Todd's sandbox?
Answer:
the perimeter is
104/5 feet or 20 4/5 ft
Step-by-step explanation:
The perimeter is a loop that surrounds, circumscribes, nor defines a two-dimensional shape and a one length.
Perimeter Calculation:A park's sandbox measures [tex]20 \ \text ft[/tex] in diameter at its base.
Todd's sandbox has a [tex]4 \ \text ft[/tex] base.
Now [tex]\frac{4}{20}=\frac{1}{5}\\\\[/tex]
As a result, the scale factor for smaller sandboxes is [tex]\ \frac{1}{5}\\\\[/tex]
[tex]\to 14 \times \frac{1}{5} = 2.8\\\\\to 18 \times \frac{1}{5}= 3.6\\\\[/tex]
As a result, in Todd's sandbox, the missing lengths (in feet) are 2.8 and 3.6.
Todd's sandbox has a perimeter of [tex]4 + 2.8 + 3.6 = 10.4[/tex] feet.

X starts at 15 and subtract 3. Y starts at 14 and subtract 3
Answer:
x: 12 9 6 3
y: 11 8 5 2
Step-by-step explanation:
Every box is the previous number minus 3. For x, they say to start with 15 and subtract 3, so the first box is 15-3. The second box is the previous box, 12, minus 3 and so on. Y is done the same way. Hope this is helpful :)
