1 answer:
Tju [1.3M]3 years ago
4 0

Answer:

a.) False

b.) True

c.) True

d.) False

Step-by-step explanation:

a.) This choice is false because you can't know for sure what will happen in the future. The statement uses the word "will" which suggests that you know for sure what will occur. However, the statement also says "tomorrow" and since no one can tell the future, this statement is false.

b.) This statement is true. Let's set up a ratio to solve this problem.

People who payed using cash : Customers

20 : 80

The statement asks about 40 customers, so we need to divide both sides by 2 in order to make the information relevant.

20 : 80

/2    /2

10 : 40

This ratio shows that 10 people would most likely pay with cash in a group of 40 customers. Therefore, the statement is accurate.

c.) The third statement is true. Let's set up a ratio to solve this problem.

People who payed using a credit card : Customers

24 : 80

To put this information in decimal form, divide 24 by 80.

24/80 = .3

Therefore, .3 customers would probably pay using a credit credit card.

d.) The more participants in a survey, the more accurate the results. Therefore, this statement is false because it states the exact opposite of the truth.

When i muiltplyied 3.675 x 10 i got 36.75. my question is why did the decimal move? and how.
qaws [65]

Answer:

It moved because of this:

Step-by-step explanation:

the number 10 has one 0 in it.

you move the decimal place over how many times depending on how many 0s there are, so because there is <u>one</u><u> </u>0 in 10, you move it over <u>once</u>.

hope this helped!

The midpoint of the segment as an ordered pair (-4,8) (-4,2)
tiny-mole [99]

Answer:

Step-by-step explanation:

(-4,8) & ( -4,2)

Midpoint=\left(\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2} \right)\\\\\\=\left(\dfrac{-4-4}{2},\dfrac{8+2}{2}\right)\\\\\\=\left(\dfrac{-8}{2},\dfrac{10}{2} \right)

= (-4,5)

To find the standard deviation of the diameter of wooden​ dowels, the manufacturer measures 19 randomly selected dowels and find
loris [4]

Answer:

Option D -  [0.12

Step-by-step explanation:

Given : The manufacturer measures 19 randomly selected dowels and finds the standard deviation of the sample to be s=0.16.

To find : The​ 95% confidence interval for the population standard deviation sigma?

Solution :

Number of sample n=19

The degree of freedom is Df=n-1=19-1=18

The standard deviation of the sample is s=0.16

Applying chi-square table to find critical value,

Upper critical value of \chi^2 is UC=\chi(\frac{0.05}{2},18) = 31.5264

Lower critical value of \chi^2 is  

LC=\chi(1-\frac{0.05}{2},18) = 8.2307

Lower limit of the 95% confidence interval for the population variance

L=\frac{(df)\times (s^2)}{UC}

L=\frac{18\times (0.16^2)}{31.5264}

L=\frac{18\times0.0256}{31.5264}

L=\frac{0.4608}{31.5264}

L=0.0146

Upper limit of the 95% confidence interval for the population variance

U=\frac{(df)\times(s^2)}{LC}

U=\frac{18\times (0.16^2)}{8.2307}

U=\frac{18\times0.0256}{8.2307}

U=\frac{0.4608}{8.2307}

U=0.0559

So, The 95% confidence interval for the population variance is [0.0146, 0.0560]

Now, The 95% confidence interval for the population standard deviation is

[\sqrt{0.0146}

[0.1208

or  [0.12

Therefore, Option D is correct.

The 95% confidence interval for the population standard deviation is  [0.12
