Answer:
Option D. 37¼ ft
Step-by-step explanation:
The perimeter of the figure above can be obtained by adding all the lengths of each sides together. This can be obtained as follow:
The lengths of each sides are given below:
Top = 6¼ ft
Left = 9⅛ ft
Bottom = 9½ ft
Right = 7¾ ft
Top horizontal = 9½ – 6¼
= 19/2 – 25/4
= 13/4 ft
Top height = 9⅛ – 7¾
= 73/8 – 31/4
= 11/8 ft
Perimeter = 6¼ + 9⅛ + 9½ + 7¾ + 13/4 + 11/8
= 25/4 + 73/8 + 19/2 + 31/4 + 13/4 + 11/8
= 149/4
= 37¼ ft
Thus, the perimeter of figure is 37¼ ft
You are jumping rope at a rate of 15 jumps every 24 seconds. At this rate, how long will it take you to jump 90 times?
Answer:
144 seconds
Step-by-step explanation:
divide 90 by 15 to get 6
if you are jumping in sets of 15, that means you need to jump 6 sets to get to a total of 90 jumps total. if every set of 15 jumps takes 24 seconds that means that 6 sets will take 144 seconds. 6 x 24 = 144

Arrange the figures in increasing order of their volumes. Use Pi =22/7
Answer:
see the list below
Step-by-step explanation:
did all the formulas for each and I believe the order is from (smallest to biggest)
1. The half sphere or hemisphere (3rd in the pic)
2.The pyramid
3.slanted cone
4.cone
5.slanted cylinder
6.and finally the cylinder
Volume of cylinder II< Volume of cylinder I< Volume of Cone II< Volume of pyramid <Volume of Cone I
What is volume?The amount of space occupied by a three-dimensional figure as measured in cubic units.
Volume of Cone I = 1/3 πr²h= 1/3*22/7*5*5*7
=25 cm³
Volume of cylinder I= πr²h= 22/7*4*4*5
= 251.42 cm³
Volume of hemisphere= 2/3*πr³= 2/3*22/7*3.5*3.5*3.5
= 89.833 cm³
Volume of pyramid = l*w*h= 10*5*6
= 100 cm³
Volume of cylinder II= πr²h= 22/7*6*6*8
= 905.14 cm³
Volume of Cone II= 1/3 πr²h= 1/3*22/7*4.5*4.5*7.5
=159.107 cm³

For one month, 500 elementary students kept a daily record of the hours they spent watching television. The average number of hours per week spent watching television was 28. The researchers conducting the study also obtained report cards for each of the students. They found that the students who did well in school tended to spend less time watching television than those students who did poorly. Listed are several possible statements concerning the results of this research. Place a check by every statement that you agree with based on this study.
a. The sample of 500 is too small to permit drawing conclusions about elementary students in general.
b. If a student decreased the amount of time spent watching television, his or her performance in school would improve.
c. Even though students who did well in school watched less television, this doesn't necessarily mean that watching television hurts school performance.
d. One month is not a long enough period of time to estimate how many hours the students really spend watching television.
e. I don't agree with any of these statements.
Answer:
a. The sample of 500 is too small to permit drawing conclusions about elementary students in general.
C. Even though students who did well in school watched less television, this doesn't necessarily mean that watching television hurts school performance.
Step-by-step explanation:
To make inferences about a general population from sample data, we must ensure that the data is considerably large enough and randomized, this is in other to ensure that the sample is representative of the population. Hence, Making conclusion about a very large population such as here, where we want to correlate performance and playing time, a very large sample which should be atleast 10% of the population should be employed. Hence, a sample of 500 ; for making Decison about general elementary students which should run into millions require more samples.
Also Recall that, correlation does not imply causation, The fact that there is a perceives relationship between grade or performance and time spent watching TV does not necessarily mean that poor grade was caused by long duration of hours spent watching television. Other, factors such as, level of intelligence, variation of teachers competence and so on may also be causal factors.

(You will get brainliest if you give a long answer) You have recently purchased a new backpack as show in the picture. The main section of the backpack is made of a rectangular prism and half a cylinder. The front pocket is also a rectangular prims. Use the diagram to find the volume of your new backpack.
Explain how you calculated the answer using complete sentences and proper grammar.
*see attachment for diagram
Answer:
Volume of new backpack = 1,299.84 in.³
Step-by-step explanation:
Volume of the new back pack = volume of the front pocket + volume of the main section of the backpack
✔️Volume of the front pocket = volume of rectangular prism = L*W*H
L = 8 in.
W = 4 in.
H = 2 in.
Volume of the front pocket = 8*4*2 = 64 in.³
✔️Volume of the main section of the back pack = volume of the rectangular prism + volume of the half cylinder
= L*W*H + ½(πr²h)
L = 12 in.
W = 10 in.
H = 7 in.
r = 6 in.
h = 7 in.
Plug in the values into the equation
Volume of the main section of the backpack = 12*10*7 + ½(π*6²*7)
= 840 + ½(791.68)
= 1,235.84 in.³
✅Total volume of the new backpack = 64 + 1,235.84 = 1,299.84 in.³

find the surface area of each figure (spheres and hemispheres)
Answer:
7. 1520.53 cm²
8. 232.35 ft²
9. 706.86 m²
10. 4,156.32 mm²
11. 780.46 m²
12. 1,847.25 mi²
Step-by-step explanation:
Recall:
Surface area of sphere = 4πr²
Surface area of hemisphere = 2πr² + πr²
7. r = 11 cm
Plug in the value into the appropriate formula
Surface area of the sphere = 4*π*11² = 1520.53 cm² (nearest tenth)
8. r = ½(8.6) = 4.3 ft
Plug in the value into the appropriate formula
Surface area of the sphere = 4*π*4.3² = 232.35 ft² (nearest tenth)
9. r = ½(15) = 7.5 m
Surface area of the sphere = 4*π*7.5² = 706.86 m² (nearest tenth)
10. r = ½(42) = 21 mm
Plug in the value into the formula
Surface area of hemisphere = 2*π*21² + π*21² = 2,770.88 + 1,385.44
= 4,156.32 mm²
11. r = 9.1 m
Plug in the value into the formula
Surface area of hemisphere = 2*π*9.1² + π*9.1² = 520.31 + 260.15
= 780.46 m²
12. r = 14 mi
Plug in the value into the formula
Surface area of hemisphere = 2*π*14² + π*14² = 1,231.50 + 615.75
= 1,847.25 mi²

The average amount of ozone in several cities across Pennsylvania was found in a study to correlate with the average number of asthma cases in those cities. What type of study was this
Answer:
Ecological study
Step-by-step explanation:
When the basis for the conclusion of a study is done an a group or population level rather than on a person, single or individual basis, then we refer to this as an ecological study. In the scenario described above, relationship between ozone in Pennsylvania and the number of asthma cases was generalized and presented on the mean or average level rather than being compared in terms of individual figure. Hence, research studies of this type or nature are classed as ecological study.

A data set of 27 different numbers has a mean of 33 and a median of 33. A new data set is
created by adding 7 to each number in the original data set that is greater than the median and
subtracting 7 from each number in the original data set that is less than the median. Which of
the following measures does NOT have the same value in both the original and new data sets?
A.Median
B.Mean
C. Sum of the numbers
D. Standard deviation
Answer:
Option D.
Step-by-step explanation:
Suppose that we have a set of N values:
{x₁, x₂, ..., xₙ}
The median is the value in the middle, and the mean is calculated as:
[tex]M = \frac{(x_1 + x_2 + x_3 ... + x_n)}{N}[/tex]
Because here we have "the median" then we will assume that N is odd, and there is only one median, the value "k" (if N was even, the median would be the mean of the two middle values, that case is really similar to the case where N is odd, so solving only one of the cases is enough)
Now we add 7 to all the values greater than the median
We subtract 7 to all values smaller than the median.
Then the median remains unchanged (because we did not add nor subtract anything to the median).
The new mean will be:
[tex]M' = \frac{(x_1 - 7) + (x_2 - 7) + ... + (x_{k}) + ... + (x_n + 7)}{N} = \frac{(x_1 + x_2 + ... + x_n) + (-7)*(n/2 - 0.5) + 7*(n/2 - 0.5)}{N} = \frac{(x_1 + x_2 + ... + x_n)}{N} = M[/tex]
So the mean does not change.
Because the mean is computed as the sum of the numbers divided by N, and the mean does not change, and N does not change, then the sum of the numbers does not change.
Finally, the standard deviation is computed as:
[tex]SD = \sqrt{\frac{(x_1 - M)^2 + ... + (xn - M)^2}{N} }[/tex]
Because M does not change, if we add or subtract numbers to some of the values, the standard deviation will change (Because all the terms are squared, so the added and subtracted sevens don't cancel like in the previous cases)
Then the only value that does not have the same value in both the original and new data sets is the standard deviation.
Can someone help please?
