1. Mean: 18 Range: 143
Step-by-step explanation:
So I can't do all these problems for you but I'll do the first one.
So basically to find the mean add all of the numbers together and divide by the number of numbers.
For example, if the numbers were 1, 2, 3, 4 you would do:
1 + 2 + 3 + 4 = 10
divide by the number of numbers (4 numbers):
10 / 4 = 2.5
so the mean of that example set is 2.5
The range of a set of numbers is the difference between the least and greatest:
From the example before, the set 1, 2, 3, 4 would have a range of 4 - 1 = 3.
For question 1, you start by adding all the numbers:
you get 162.
Then, divide by 9 because there are 9 numbers:
162/9 = 18
Range: the least number is -76 and the greatest number is 67, so the range is:
67 - (-76) = 143

show that the equation x^3 + x - 3 has a solution between 1 and 2
Answers
Answer:
see explanation
Step-by-step explanation:
Evaluate the polynomial at x = 1 and x = 2
x = 1 : 1³ + 1 - 3 = 1 + 1 - 3 = - 1
x = 2 : 2³ + 2 - 3 = 8 + 2 - 3 = 7
Then ( 1, - 1 ) → (2, 7 )
Shows the polynomial goes from y = - 1 to y = + 7
The change in sign indicates the graph crosses the x- axis between 1 and 2
Thus indicating a solution between x = 1 and x = 2

Mark spends $36 at a basketball game. He buys a T-shirt for $22. He then buys a bottle of water for $4 and 2 tacos. How much is each taco?
Answers
Answer:
each taco is $7.
Step-by-step explanation:
In total he spent $36. He bought a shirt for $22 and a bottle of water for $4.
22+4= 26
36-22= 14
14 divided by 2= 7
Answer:
each taco is $5.
Step-by-step explanation:
Let's think about like Mark starts off with $36. Take away $22 for that t-shirt he bought. Now he has $14. He uses $4 for water, now he has $10. The rest of his money is spent on tacos. $10/2 tacos is $5 for each taco. :)

Ethan invested $9,500 in an account paying an interest rate of 2 3/4% compounded monthly. Henry invested $9,500 in an account paying an interest rate of 3 3/8% compounded quarterly. After 9 years, how much more money would Henry have in his account than Ethan, to the nearest dollar?
Answers
Answer:
691
Step-by-step explanation:
Henry would have $1,005.94 more than Ethan in his account after 9 years.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To solve this problem, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^(^n^t^)[/tex]
where A is the amount after t years,
P is the principal
r is the annual interest rate,
n is the number of times the interest is compounded per year, and
t is the time in years.
For Ethan:
P = $9,500, r = 2.75% = 0.0275 (since it is compounded monthly, n = 12), and t = 9
[tex]A = 9,500(1 + 0.0275/12)^(^1^2^\times^9^)[/tex]
= $12,817.84
For Henry:
P = $9,500,
r = 3.375% = 0.03375 (since it is compounded quarterly, n = 4), and
t = 9
[tex]A = 9,500(1 + 0.03375/4)^(^4^\times^9^)[/tex]
= $13,823.78
The difference in the amounts is:
$13,823.78 - $12,817.84 = $1,005.94
Therefore, Henry would have $1,005.94 more than Ethan in his account after 9 years.

A company was able to incite staff from 100 employees to 214 employees. What was the percentage increase in staff
Answers
Answer:
114%
Step-by-step explanation:
A company was able to incite staff from 100 employees to 214 employees. What was the percentage increase in staff?
Percentage Formula is given as:
New value - Old value/Old value × 100%
New value = 214
Old value = 100
Hence:
Percentage increase = 214 - 100/100 × 100
= 114/100 × 100
= 114 %
Therefore, the percentage increase = 114%
A farmer is creating a budget for planting soybeans and wheat. Planting soybeans costs $200 per acre and planting wheat costs $500 per acre. He wants to spend no more than $100,000 planting soybeans and wheat. What is the "multiplier" for soybeans?
Answers
Answer:
5 acres < soybeans < 495
2 acres < wheat < 198 acres
Step-by-step explanation:
If farmer plans to plant minimum of soybeans, it should be 5 acres of soybeans costing $1000. The remaining cost of $98,000 will be available for maximum of wheat, i.e., 198 acres of wheat.
Similarly, if we go for minimum possible planting for wheat, it should be 2 acres, and then resulting in 495 acres for soybeans
5 acres < soyabeans < 495
2 acres < wheat < 198 acres
Answer:
The multiplier for soybeans is 200, which is dollars per acre.
Step-by-step explanation:
5 acres ≤ soybeans ≤ 495 acres (constraint)
2 acres ≤ wheat ≤ 198 acres (constraint)
150w + 125s = 100,000
This would represent 150 acres of wheat and 125 acres of soybeans. The acres of wheat would add up to $75,000 because 150 x 500 = 75,000 and the acres of soybeans would add up to $25,000 because 125 x 200 = 25,000. (example of a solution, there are more possible)

Hector's family traveled 7 10 of the distance to his grandmother's house on Saturday. They traveled 2 3 of the remaining distance on Sunday. What fraction of the total distance to his grandmother's house was traveled on Sunday?
Answers
Answer: 1 / 5 of the total distance.
Step-by-step explanation:
They traveled 7/10 of the distance on Saturday. This means that on Saturday, the fraction left was:
= 1 - 7/10
= 3/10 of the distance
On Sunday, they traveled 2/3 of this remaining distance. The fraction of the distance traveled is therefore:
= 2/3 * 3/10
= 6 / 30
= 1 / 5 of the total distance.
