In Terrance County, 85% of eligible voters are registered to vote, and
government records from a recent gubernatorial election indicate that 60%
of registered voters actually voted in the election. If there are 21,800
eligible voters in Terrance County, how many people voted in the recent
qubernatorial election?
Answers
Answer:
11118 people voted
Step-by-step explanation:
Given
\(Eligible\ Voters = 21800\)
\(Registered\ Voters = 85\%\)
\(Voted\ Voters = 60\%\)
Required
Determine the number of voters
First, we need to determine the number of registered voters.
\(Number = \%Registered\ Voters * Eligible\ Voters\)
\(Number = 85\% * 21800\)
\(Number = 18530\)
Next, we determine the actual voters using
\(Voters = \%Voters * 18530\)
\(Voters = 60\% * 18530\)
\(Voters = 11118\)
Hence, 11118 people voted
Find the inverse of A = 9, -2 -10, 7 , if it exists.
Answers
The inverse of matrix A, if it exists, is:
A^(-1) = [7/43, 2/43; 10/43, 9/43]
To find the inverse of a matrix A, we need to determine if the matrix is invertible by calculating its determinant. If the determinant is non-zero, then the matrix has an inverse.
Given the matrix A = [9, -2; -10, 7], we can calculate its determinant as follows:
det(A) = (9 * 7) - (-2 * -10)
= 63 - 20
= 43
Since the determinant is non-zero (43 ≠ 0), we can proceed to find the inverse of matrix A.
The formula to calculate the inverse of a 2x2 matrix is:
A^(-1) = (1/det(A)) * [d, -b; -c, a]
Plugging in the values from matrix A and the determinant, we have:
A^(-1) = (1/43) * [7, 2; 10, 9]
Simplifying further, we get:
A^(-1) = [7/43, 2/43; 10/43, 9/43].

A 4-cup bottle of shampoo costs $10.24. What is the price per pint?
Answers
Answer:
Step-by-step explanation:
There are 2 pints in 1 quart, and 4 quarts in 1 gallon, so there are:
2 pints/quart x 4 quarts/gallon = 8 pints/gallon
To find the price per pint of shampoo, we need to first convert the volume of the bottle from cups to pints. There are 2 cups in 1 pint, so a 4-cup bottle of shampoo contains:
4 cups / 2 cups per pint = 2 pints
The price per pint of shampoo can then be calculated as:
$10.24 / 2 pints = $5.12 per pint
Therefore, the price per pint of shampoo is $5.12.
Answer:
$5.12
Step-by-step explanation:
1 cup = 0.5 pint
4 cup = 2 pints
What is the price per pint?
10.24 / 2 = $5.12
So, the cost per pint is $5.12

4) Assume that Ryan does save 10% for retirement. If he allocates the remainder of his take-home pay to entertainment compromise of the total monthly budget? How much will be budgeted towards entertainment?
Answers
The percent of his monthly budget that his transport costs account for will be 17.8%.
How to calculate the percentage?The percent of his monthly budget that his transport costs account for will be:
= 325/(800 + 450 + 125 + 325 + 125) × 100
= 325/1825 × 100
= 17.8%
The percent of his monthly budget has he accounted for will be:
= 1825/2500 × 100
= 73%
When he saves 10% of his take-home pay towards retirement, the amount saved will be:
= 10% × $2500
= $250

https://brainly.com/question/24304697
The percent of Rayan's monthly budget that his transport costs account for will be 17.8%.
1. The proportion of his monthly budget that his transit expenses make up is:
= 325/(800 + 450 + 125 + 325 + 125) × 100
= 325/1825 × 100
= 17.8%
The proportion of his monthly budget that he has already accounted for is:
= 1825/2500 × 100
= 73%
He will save the following sum for retirement if he sets aside 10% of his after-tax income:
= 10% × $2500
= $250
The answer is $250.
2. To find the percentage of his monthly budget accounted for by transport costs, we add up the amounts for Car Payment and Gas:
$325 + $125 = $450.
Then we calculate the percentage: (450 / 2500) x 100% = 18%. Therefore, his transport costs account for 18% of his monthly budget.
3. To find the percentage of his monthly budget accounted for overall, we sum up all the amounts in the table:
$800 + $450 + $125 + $325 + $125 = $1,825.
Then we calculate the percentage: (1825 / 2500) x 100% = 73%. Therefore, he has accounted for 73% of his monthly budget.
4. To calculate how much Ryan can save each month for retirement, we take 10% of his take-home pay:
10% of $2,500 = $250.
Thus, he can save $250 each month for retirement.

7.) The mean rate for a satellite television from a sample of households was $51.00 per month,
with a standard deviation of $2.00 per month. Between what two values do 75% of the data lie?
(Assume a bell-shaped distribution.) (HINT: Chebychev's Theorem)
Answers
Answer: 75% of the rate lies in 47 per month and 55 per month.
Step-by-step explanation:
The mean rate for a satellite television from a sample of households was $51.00 per month, with a standard deviation of $2.00 per month.
According to the Chebychev's Theorem, atleast \((1-\dfrac{1}{k^2})\) % of the data lies within k standard deviation from the mean.
For k=2
\(1-\dfrac1{2^2}=1-\dfrac14=\dfrac34=0.75\ or \ 75\%\)
Alteast 75% of data lies within 2 standard deviation from mean.
i.e. 51-2(2) per month and 51+2(2) per month
i.e. 47 per month and 55 per month
Hence, 75% of the rate lies in 47 per month and 55 per month.
