Answer:
Assume that we want 90% confidence that the sample mean is within one-half year of the population mean. Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? The required sample size is . (Round up to the nearest whole number as needed.) Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? A. Yes, because statistics students are typically younger than people in the general population. O B. No, because there is no age difference between the population of statistics students and the general population. O C. No, because statistics students are typically older than people in the general population.

A house cleaning company charges a constant rate for each hour of cleaning. They charge $135 for 3 hours of cleaning.
Number of hours cleaning
Amount charged for cleaning (in dollars)
3
$135
18
How much would the company charge for 18 hours of cleaning?
$675
⊝
$810
⊝
$2,430
⊝
$45
⊝
Answer: $810 (B)
Step-by-step explanation: first youd need to find how much they pay for 1 hour. In this case, itd be 135/3 = 45. now multiply by 18 (because 1 hr x 18 = 18 hrs). this would get you to 810.

A company that teaches self-improvement seminars is holding one of its seminars in
Hampton. The company pays a flat fee of $69 to rent a facility in which to hold each session.
Additionally, for every attendee who registers, the company must spend $15 to purchase
books and supplies. Each attendee will pay $18 for the seminar. Once a certain number of
attendee register, the company will be breaking even. How many attendees will that take?
What will be the company's total expenses and revenues?
Step-by-step explanation:
I take it that the $69 flat fee is for one event.
and we are talking about one event overall.
"breaking even" means that the sum of all expenses and revenues is 0.
so, with x being the number of attendees,
0 = 18x - 15x - 69
69 = 3x
x = 23
that means, with 23 attendees they will break even, and with every attendee more they will gain.
in the case of 23 attendees the company will have expenses of 69 + 23×15 = $414.
and the revenues are 23×18 = $414

A shipment of sugar fills
4/9 containers. If each container holds 2 2/5
tons of sugar, what is the amount of sugar in the entire shipment?
Write your answer as a mixed number in simplest form.
Answer:
For this problem, multiply these fractions.
First, make each one an improper fraction: 2 4/5 is the same as 14/5 and 2 3/7 is the same as 17/7.
Now, 14/5 times 17/7 yields 238/35 which reduces to 34/5. This may be expressed also as the mixed fraction 6 4/5.
So, the shipment contains 6 4/5 tons of sugar. (This is also equal to 13,600 pounds of sugar.)

A collection of 40 dimes and nickels
is worth $2.90. How many nickels are
there? (Hint: In your equation, use
290¢ instead of $2.90.)
9514 1404 393
Answer:
22 nickels18 dimesStep-by-step explanation:
Let d represent the number of dimes (the higher-value coin). Then the number of nickels is 40-d, and the total value in cents is ...
5(40 -d) +10(d) = 290
200 +5d = 290
5d = 90
d = 18
40 -d = 22
There are 22 nickels (and 18 dimes).
_____
Additional comment
If you write the equation in terms of the number of nickels (n), you end up with the equation -5n = -110. The formulation used above avoids negative numbers, which can be confusing for some people.

Answer:
[tex]2(x+11y)[/tex]
Step-by-step explanation:
Rearrange:
[tex]10x-7x-x+13y+9y[/tex]
Subtract and Add:
[tex]2x+22y[/tex]
Simplify:
[tex]2(x+11y)[/tex]
Answer:
x + 11y
Step-by-step explanation:
Working in parts starting with x...
10x-7x = 3x
3x - x = 2x
Moving on to y...
13y + 9y = 22y
Put it together
2x + 22y
Simplify by dividing both by a common number ( in this case 2)
x + 11y
The cost (c) to buy gasoline for a car varies directly to the amount of gas (g) in gallons purchased. Helen spent $16.72 on 8 gallons of gas for her car. Nathan is buying the same gasoline, but only has $10.45 to spend. How many gallons of gas can Nathan buy? How do you know?​
Answer:
5 gallons
Step-by-step explanation:
1) How much did Helen spend per gallon?
16.72/8 = $2.09/gallon
2) 2.09g = 10.45
10.45/2.09 = g

Below are two parallel lines with a third line intersecting them 107
Answer:
x° = 107°
Step-by-step explanation:
Given that m < 107° and m < x° are alternate interior angles that do not have a common vertex on alternate sides of the transversal, then it means that they have the same measure. It also implies that their supplements will have the same measure, 73°.
Therefore, x° = 107°.
Please mark my answers as the Brainliest, if you find this helpful :)
Answer:
107
Step-by-step explanation:
they r on opposite sides so they are the same.
What is an equation of the line that passes through the point (-8, -1) and is
parallel to the line x – 4y = 4?
Answer:
y = 1/4x + 1
Step-by-step explanation:
x - 4y = 4
x - 4 = 4y
1/4x - 4/4 = y
1/4x -1 = y
Slope: 1/4
Point: (-8,-1)
y-intercept = -1 - (1/4)(-8)=
-1 + 2 = 1
Solve for x !!!!!!!!
Answer:
x = 9
Step-by-step explanation:
to find the value of x
11x - 11 = 110 (alternate exterior angles are equal)
Substitute
11x = 110 -11
11x = 99
x = 99 ÷ 11
x = 9
Answer:
x=11
Step-by-step explanation:
Because 110= 11x-11, you can use this equation to solve.
First, add 11 to both sides:
121=11x
Then divide by 11:
11=x ------> x=11

Answer:
-31/4
Step-by-step explanation:
[tex]\frac{1}{2} ^{2}[/tex] is actually just (1/2)(1/2) and that equals 1/4
2 - (2/3) you can simplify to (6/3) - (2/3). that equals 4/3
now put it together!
(1/4) - 6(4/3)
(1/4) - (24/3) --------> (which simplifies to 8)
1/4 - 8 ----> (now you have to simplify this to match 1/4 denominator)
(1/4) - (32/4)
-31/4

solve 2(n + 5) = 15
solve a + a + a + a = 24
solve 4c + 6 = 18
please answer with an explanation
50 points given with explanation
Step-by-step explanation:
♤ 3(b-5) = 27
=> 3b - 15 = 27
=> 3b = 27 + 15 = 42
=> b = 42/3
=> b = 14 (Ans)
♤ 2x/3 = 6
=> 2x = 6 × 3 = 18
=> x = 18/2
=> x = 9 (Ans)
♤ 2(n + 5) = 15
=> 2n + 10 = 15
=> 2n = 15 - 10 = 5
=> n = 5/2
=> n = 2.5 (Ans)
♤ a + a + a + a = 24
=> 4a = 24
=> a = 24/4
=> a = 6 (Ans)
♤ 4c + 6 = 18
=> 4c = 18 - 6 = 12
=> c = 12/4
=> c = 3 (Ans)

Jim rented a truck for one day . There was a base fee of $18.95 and there was an additional charge of 74 cents for each mile driven . Jim had to pay $119.59 when he returned the truck . For how many miles did he drive the truck ??
Answer:
136 miles
Step-by-step explanation:
subtract $119.59 with how much he rented the truck for, which is $18.95 which makes his money at $100.64, then divide by how much each mile costed which was 74 cents
which gives you 136 so 136 miles.
Hope this helps :)
