how many people in the town of summit have jobs if there are 9,255 people in the town and 1/3 of them are employed? simplify the fraction if possible
Answer:
divide 9,255 divide 1/3 and you will get your answer hope this helps :)))
Step-by-step explanation:
In the town of Summit, 3,085 people have jobs. If there are 9,255 people in the town and 1/3 of them are employed.
To find the number of people in the town of Summit who have jobs, we can multiply the total population by the fraction representing the employed individuals.
Total population = 9,255 people
Fraction employed = 1/3
Number of people employed = Total population * Fraction employed
Number of people employed = 9,255 * (1/3)
To simplify the fraction (1/3), we can divide both the numerator and denominator by their greatest common divisor, which is 1 in this case.
Dividing 1 and 3 by 1, we get:
1/1 = 1
3/1 = 3
So, the simplified fraction is 1/3.
Continuing the calculation:
Number of people employed = 9,255 * (1/3)
Number of people employed = 9,255 / 3
Number of people employed = 3,085
Therefore, in the town of Summit, 3,085 people have jobs.

Why do you think adding and subtracting polynomial expressions is like adding and subtracting
expressions?
Answer:
Polynomials are closed under addition and subtraction, which is fancy mathspeak that means that whenever we add or subtract two polynomials, we always get another polynomial. In that way, they behave a lot like the numbers you're probably already familiar with. Adding and subtracting:
Two integers gives you another integerTwo rational numbers gives you another rational numberTwo real numbers gives you another real numberAnd it works the same with polynomials!
Express as a difference: a+5
The expression expressed as a difference is (a - 2) - (-7).
We have,
We can express a + 5 as a difference by subtracting a suitable term from it.
One way to do this is to subtract 2 and add 2, like this:
a + 5 = a + 5 - 2 + 2 (adding and subtracting 2)
= (a - 2) + 7 (rearranging)
Now,
We can express a + 5 as the difference between a - 2 and -7, like this:
a + 5 = (a - 2) - (-7)
Thus,
The expression expressed as a difference is (a - 2) - (-7).

The Mean Corporation would like to invest in the booming health food industry. It is considering the creation of a health-drink franchise called Goose Juice. The investment department of the Mean Corporation wants to investigate the feasibility of this venture by examining the profits of similar franchises. It believes that the venture will be feasible if an average annual profit of more than $85,000 can be expected from each Goose Juice that is opened. It is known that the annual profits earned by health-drink franchises has a population standard deviation of $8,700.
The Mean Corporation's statisticians would like to construct a hypothesis test for the population mean annual profit earned by health-drink franchises. A random sample of 50 franchises was chosen and their annual profit for the previous financial year was recorded. The mean annual profit for the sample was calculated as $82,441.
The hypotheses that were used by the statisticians were
Null hypothesis: population mean = 81,000, Alternative hypothesis: population mean > 81,000 and the test statistic was found to be 1.29 (to 2 decimal places).
Required:
Calculate the p-value for this test, giving your answer as a decimal to 4 decimal places.
Answer:
The p-value is approximately 0.9015
Step-by-step explanation:
The statistic parameters are;
The population mean, μ₀ = $85,000
The population standard deviation, σ = $8,700
The size of the sample, n = 50
The sample mean annual profit, [tex]\bar x[/tex] = $82,441
The null hypothesis, H₀: μ = 81,000
The alternative hypothesis, Hₐ: μ > 81,000
Given that n > 30, a z-test is used
The test statistic ≈ 1.29
Therefore, we have;
[tex]z=\dfrac{\bar{x}-\mu_0 }{\dfrac{\sigma }{\sqrt{n}}} = 1.29[/tex]
From the z-score, the p value for a test statistic of 1.29 = 0.90147 which is 0.9015 after rounding up to 4 decimal places

#4: S = {(|k+1|+2, 4), (8, 7)}
Will give 100 points and Brainliest!
Answer:
See belowStep-by-step explanation:
The relation is not a function when x -value is same but y- values are different.
#1
k^2 = 4kk = 0, k = 4#2
k^2 - 5k = k + 7k^2 - 6k = 7k^2 - 6k + 9 = 16k - 3 = 4 ⇒ k = 7k - 3 = -4 ⇒ k = -1#3
k^3 - 5k^2 + 3k = -kk^3 - 5k^2 + 4k = 0k(k^2 - 5k + 4) = 0k = 0, k = 1, k = 4#4
|k + 1| + 2 = 8|k + 1| = 6k = 5, k = -7absolute value of -93
Answer:

The absolute value is just how far from away from zero a number is.
Evaluate: x + (x2 - xy) - y
if x = 5 and y = 4
When x = 5 and y = 4, the expression [tex]x + (x^2 - xy) - y[/tex] evaluates to 6.
To evaluate the expression [tex]x + (x^2 - xy) - y[/tex] when x = 5 and y = 4, we substitute the given values into the expression and perform the
calculations:
[tex]x + (x^2 - xy) - y\\x= 5 + (5^2 - 5*4) - 4\\x= 5 + (25 - 20) - 4\\x= 5 + 5 - 4\\x= 10 - 4\\x= 6\\[/tex]
It's crucial to remember that the expression in question is not an equation that represents a graph, nevertheless. It is merely an algebraic expression that, given the values of "x" and "y," evaluates to a single value. We need an equation that connects 'x' and 'y' and specifies the relationship between them if we are to construct a graph.
Therefore, when x = 5 and y = 4, the expression [tex]x + (x^2 - xy) - y[/tex] evaluates to 6.

a. There is a 98 percent probability that the slope of the population regression line is between $315 per point and $336 per point.
b. Ninety-eight percent of the time, a 10-point increase in placement score will result in an average increase between $3,150 and $3,360 in starting salary.
c. We are 98 percent confident that a 10-point increase in placement score will result in a predicted increase in starting salary of between $3,150 and $3,360.
