The normal rainfall in September for Denver is 1.24 inches. The normal rainfall for Miami in September is 7.63 inches. The normal rainfall in January for Miami is 2.01 inches. The normal rainfall in January for Denver is 6.91 inches.
To the nearest tenth of an inch, how much more rain does Miami get in September than it gets in January?
Answer:
5.60 inches
Step-by-step explanation:
7.63 - 2.01 = 5.62
5.62 ≈ 5.6
Tell me if there is any missing information in the question because the information for Denver seems useless and there probably something missing
Jim and Jabu join a gym. Jim's gym take R150 deposit,and he pays R120 monthly. Jabu's gym takes no deposit, but his monthly payment is R150. They compare their total payments after four months, after five months and after six months.
3.1 Reasoning
3.2 Number sentence
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.

A random sample of 900 13- to 17-year-olds found that 411 had a computer in their room with Internet access. Let p be the proportion of all teens in this age range who have a computer in their room with Internet access.Suppose you wished to see if the majority of teens in this age range have a computer in their room with Internet access. To do this, you test the hypotheses
H0: p = 0.50 vs HA : p≠0.50
The test statistic for this test is:_______.
a. 1.96
b. 2.60
c. 27.50
d. 2.59424
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:
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

11.) Jim took out a loan for $500. The
rate is 8%. How much does Jim owe
in interest if he pays it back in 4
years?
The amount Jim owes in interest if he pays it back in 4 years is $160
Calculating Simple interestFrom the question, we are to calculate how much Jim owes in interest
Using the simple interest formula,
I = PRT
Where I is the interest
P is the principal
R is the rate
and T is the time
From the given information,
P = $500
R = 8% = 8/100 = 0.08
T = 4 years
Putting the parameters into the formula, we get
I = 500 × 0.08 × 4
I = $160
Hence, the amount Jim owes in interest if he pays it back in 4 years is $160

Rearrange the equation so n is the independent variable.
3m-2n=12
Answer:
[tex] \displaystyle m = \frac{2}{3} n + 4[/tex]
Step-by-step explanation:
we are given a equation
we want to make n the independent variable
to do so
move -2n to right hand side and change its sign:
[tex] \displaystyle 3m = 12 + 2n[/tex]
divide both sides by 3:
[tex] \displaystyle m = \frac{12 + 2n}{3} [/tex]
further simplification is needed:
[tex] \displaystyle m = \frac{12 }{3} + \frac{2n}{3} [/tex]
[tex] \displaystyle m = \frac{2}{3} n + 4[/tex]
now m depends on n and n can be any value so we have rearranged n to independent variable

Someone has offered you a wager on the outcome of a die roll. You will pay him
$100 for each time the standard, six-sided die lands on one, and he will pay you $30 for each time the die lands on any other number. Without your awareness, he has loaded the die so that it has a 40% change to land on the number one, and besides
that an equal change to land on any of the values 2 through 6.
What is the expected value of one round of gambling in this scenario?
-$12
-$32
$2
-$22
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
A = event of landing on "1".B = event of landing on anything else (2 through 6).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:
P(A) = 0.40P(B) = 0.60V(A) = -100V(B) = 30Multiply the corresponding probability and net value items together
P(A)*V(A) = 0.40*(-100) = -40P(B)*V(B) = 0.60*30 = 18Then 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.
