Answer:

The test statistic for this test is: z = -2.60, option b.

Step-by-step explanation:

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

H0: p = 0.50 vs HA : p≠0.50

This means that [tex]\mu = 0.5, \sigma = \sqrt{0.5*0.5} = 0.5[/tex]

A random sample of 900 13- to 17-year-olds found that 411 had a computer in their room with Internet access.

This means that [tex]n = 900, X = \frac{411}{900} = 0.4567[/tex]

Value of the test-statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.4567 - 0.5}{\frac{0.5}{\sqrt{900}}}[/tex]

[tex]z = -2.598[/tex]

The test statistic for this test is: z = -2.60, option b(should be).

q(x=f(x-h+k

here, h=0, k=-8, so

to translate f(x) 8 units down, we have

q(x)=f(x-0)-8

=2x^2-3x+5-8

=2x^2-3x-3

Answer:

10/6 = 1 and 2/3

Step-by-step explanation:

10 pounds of candy, 6 bags.

that means 10 divided by 6, or 10/6

simplify that 10-6 = 4, 6 can only be subtracted once, so it is 1 and 4/6 or 2/3

2/3 is 0.666666... so add it together and you get 1.66666... or 1 and 2/3

Answer: the answer is 42.

Step-by-step explanation:

This is how you solve.

Take 140 and divide by 10.

You would get 14.

then, times 14 by 3 or add it 3 times.

14+14+14 is equal to 42.

Answer: $214

Step-by-step explanation:

First find how much you would have to pay if you payed $92 for 12 months. It would be 1104 (12 times 92)

Then you have to substract how much it would cot to pay by cash rather than paying $92 for 12 months. ( 1104-890 = 214)

Your answer is $214. You would save $214 if you pay by cash.

I hope this helps! May God bless you! :)

Answer:

What should I answer?

Step-by-step explanation:

Jim's payment is more than Jabu's after four months and Jabu's payment is more than Jim’s after five months.

It is given that Jim’s gym takes a deposit of 150 and a monthly charge of 120.

Let x be the number of months for which both are paying the charges.

Then, Jim's total charge=150+120x.

Now, Jabu’s gym takes no deposit and takes a monthly charge of 150.

Jabu’s gym total charge=150x

Substitute x=4 in the obtained expression to determine the total payment of both after four months.

Jim's total charge=150+120(4)

=150+480

=620

​Jabu’s gym total charge=150(4)

=600

So, Jim's payment is more than Jabu after four months.

Substitute x=5 in the obtained expression to determine the total payment of both after five months.  

Jim's total charge=150+120(5)

=150+600

=750

Jabu’s gym total charge=150(5)

=750

​So, Jabu's payment is more than Jim’s after five months.

Therefore, Jim's payment is more than Jabu's after four months and Jabu's payment is equal to Jim’s after five months.

Step-by-step explanation:

You'll lose on average $22 per roll.

====================================================

Explanation:

Normally there is a 1/6 chance to land on any given side of a standard die, but your friend has loaded the die in a way to make it have a 40% chance to land on "1" and an equal chance to land on anything else. Since there's a 40% chance to land on "1", this leaves 100% - 40% = 60% for everything else.  

Let's define two events

So far we know that P(A) = 0.40 and P(B) = 0.60; I'm using the decimal form of each percentage.

The net value of event A, which I'll denote as V(A), is -100 since you pay $100 when event A occurs. So we'll write V(A) = -100. Also, we know that V(B) = 30 and this value is positive because you receive $30 if event B occurs.

To recap things so far, we have the following:

Multiply the corresponding probability and net value items together

Then add up those products:

-40+18 = -22

This is the expected value, and it represents the average amount of money you earn for each dice roll. So you'll lose on average about $22. Because the expected value is not zero, this means this game is not mathematically fair.

This does not mean that any single die roll you would lose $22; instead it means that if you played the game say 1000 or 10,000 times, then averaging out the wins and losses will get you close to a loss of $22.
