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.

Think about it like simple multiplication. On the number line, there are two groups of 3, except the integer is actually negative. It's about the same though.

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).

Answer:

you have got your mark in fraction.

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.

hope This helped!

Step-by-step explanation:

[tex]S _{n} = \frac{n}{2} (2a + (n - 1)d) \\ S _{14} = \frac{14}{2} ((2 \times 101) + (14 - 1) \times -3) \\ =1,141[/tex]

Answer:

49π

Step-by-step explanation:

Are of the circle equal π[tex]r^{2}[/tex] (where π is pi and "r" is the radius). Radius equals the diameter divided by 2. Therefore the area of this circle equals...

[tex](14 / 2)^{2}[/tex]π = [tex]7^{2}[/tex]π = 49π

Answer:

12

Step-by-step explanation:

The missing number is the y-intercept (b) of the table of values given.

Since we already know from the equation that the slope (m) = -³/2, therefore to find y-intercept (b) substitute the coordinates of a pair of value, say (x, y) = (4, 6), and m = -³/2 into y = mx + b

Thus,

6 = -³/2(4) + b

6 = -6 + b

6 + 6 = b

b = 12

The missing number is 12.

Which will give you:

[tex] y = -\frac{3}{2}x + 12 [/tex]

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.

margin of error is t(0.995 df=67)*s/sqrt(n)

t=2.65

the margin of error is 2.65*885/sqrt(68)=$284.40

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.
