1 (part 2). For the following data set: 52, 54, 43, 48, 37, 51, 39, 41, what is the 5 Median?
Answers
Answer:
45.5
Step-by-step explanation:
First, you need to put the data in order: 37, 39, 41, 43, 48, 51, 52, 54
I'm not sure what 5 median means, but to find the median, you look for the middle number of the data set.
43 + 48 = 91
then, you divide the numbers by 2 to get the median.
91/2= 45.5
So, the median is 45.5

In which number does the digit 2 have a value that is ten times as great as the value of the digit 2 in the number 135,284?
PLEASE HELP!
Answers
Answer:First and foremost, we should note that the value of the digit 2 in the number 135,284 is (200). Therefore, the value that is ten times as great as the value of the digit 2 in the number 135,284 would be:
= 10 × 200
= 2000
Therefore, the 2 must be in the thousands place. This can be seen in numbers such as:

A random sample of size 32 is selected from population X, and a random sample of size 43 is selected from population Y. A 90 percent confidence interval to estimate the difference in means is given as (−1.25,0.87)
.
Consider a change in the sample sizes such that a random sample of size 52 is selected from population X and a random sample of size 63 is selected from population Y. When all other things remain the same, what effect would such a change have on the interval?
Answers
Answer:
The level of confidence will increase.
Step-by-step explanation:
Could be wrong
The change in the sample size will lead to a decrease in the width of the interval.
What is a sample size?
A sample size simply means the number of subjects that are taken from the population for research.
In this case, increasing the sample size will decrease the standard error and therefore, the width of the confidence interval will reduce.
Therefore, as the sample size increases, the interval reduces.

A boy pulls the handle of a lawn mower at an angle of 30° to the horizontal with a force
of 120N. Calculate the work done when the mower moves through a distance of 12.8m.
(3mks)
Answers
If the mower is pulled over a flat horizontal surface, then first get the component of the force in the direction of the mower's displacement:
(120 N) cos(30°) = 60 √3 N ≈ 103.923 N
Then the work done by the boy on the mower over a distance of 12.8 m is
(103.923 N) (12.8 m) ≈ 1330.2 Nm ≈ 1330 J
Element X is a radioactive isotope such that every 30 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 100 grams, how long would it be until the mass of the sample reached 64 grams, to the nearest tenth of a year?
Answers
Answer:
19.3 years
Step-by-step explanation:
Given that the initial mass of a sample of Element X is 100 grams,
The formula is given as:
N(t) = No × (1/2) ^t/t½
Element X is a radioactive isotope such that every 30 years, its mass decreases by half.
N(t) = Mass after time (t)
No = Initial mass = 100 grams
t½ = Half life = 30 grams
N(t) = 100 × (1/2) ^t/30
How long would it be until the mass of the sample reached 64 grams, to the nearest tenth of a year?
This means we are to find the time
N(t) = 100 × (1/2) ^t/30
N(t) = 64 grams
64 = 100(1/2)^t/30
Divide both sides by 100
64/100 = 100(1/2)^t/30/100
0.64 = (1/2)^t/30
Take the Log of both sides
log 0.64 = log (1/2)^t/30
log 0.64 = t/30(1/2)
t = 19.315685693242 years

A polr has a shadow that is 15 feet long.Mary is 4 feet tall and her shadows is 10 feet tall how tall is the pile
Answers
Answer:
The pole is 6 feet tall.
Step-by-step explanation:
The height makes the perpendicular and the shadow makes the base of the triangle in the given question
Pole Mary
Height x 4
Shadows 15 10
If the height is taken along y- axis and shadow is taken along x axis
Then
tan alpha = Perpendicular/ base
for Mary Tan alpha = 4/10
For the pole = tan alpha = x/15
Comparing x/15= 4/10
x= 4*15/10= 60/10= 6
The pole is 6 feet tall.
