Perimeter of a square = 20 feet = 4a
=>4a = 20

=>a = 5 feet
Area of a square = a²
=>a² = 5²
=>a = 25 square feet

Researchers are investigating whether people who exercise with a training partner have a greater increase, on average, in target
Sphinxa [80]

Answer:

we have to compare the effects of method I and method II.

(a)

(i) The population of generalization if the method I is used will be all people who are willing to determine the effect of exercising with a training partner as compared to exercising alone.

(ii) The population of generalization, if method II is used, will be all people who exercise at a community fitness center.

(b)

If both the methods produce significant results then the difference between the conclusion of the method I and the conclusion of method II is that the result of the method I can be generalized to a broader population since it does not restrict people to participate in the study.

1. Arjun puts £750 into his savings account. The account earns 5% simple interest per annum. After 4 years, how much money will
musickatia [10]

Answer:

1. 900

2. 350

Step-by-step explanation:

the formula,

A= P(1+rt)

A= final amount

P= starting amount

r= intrest rate

t= time

1. A=750(1+.05*4)

A=750(1.2)

A=900

2. A=1500(1+.1*2)

A=1500(1.1)

A=1650

But theyre

asking for how much intrest will they get back, so you subtract the new amount by the starting amount to find how much intrest was earned

1650-1500=350

On a coordinate plane, solid circles appear at the following points: (negative 2, negative 5), (negative 1, 3), (1, negative 2),
podryga [215]

Answer:

Last option: It is not a function because there are two different y-values for a single x-value.

Step-by-step explanation:

It is necessary to remember that, by definition, a relation is a function if each input value (x-value)  has one and only one output value (x-value) .

In this case, the following points:

(-2, -5), (- 1, 3), (1, -2), (3, 0), (4,- 2), (4, 4)

You can observe that the input value 4 (x=4) has two ouput values. These are:

y=-2\\\\ y=4

Therefore, since there are two different y-values for a single x-value, you can conclude that the given graph is not a function.

A distribution data has a maximum value of 96, a median value of 56.5, and a minimum of 23. Use the range rule of thumb to estim
denis-greek [22]

Answer:

 The standard deviation estimate by the Range Rule of Thumb = 18.3

Step-by-step explanation:

i) maximum = 96

ii) minimum = 23

iii) standard deviation \approx  \frac{(maximum\hspace{0.1cm} - \hspace{0.1cm} minimum)}{4}  = \frac{96 - 23}{4}  = \frac{73}{4}  = 18.25

 

   The standard deviation estimate by the Range Rule of Thumb = 18.3
