Find the area . I'm begging
Answer:
274.05 (I assume they round it to A. 274.1)
Step-by-step explanation:
The figure seems to be comprised of 7 triangles, each of base 8.7 and height 9.
total area would be
7 * (8.7 * 9 / 2) = 7 * 39.15 = 274.05
4) Find a solution to the following system of equations by graphing
X-y = 11
X-y = 5
!SHOW WORK PLEASE!
Answer:
No solution
Step-by-step explanation:
Given
[tex]x - y = 11[/tex]
[tex]x - y = 5[/tex]
Required
Solve by graph
See attachment for graph.
From the attachment, lines [tex]x - y = 11[/tex] and [tex]x - y = 5[/tex] do not intersect. This implies that, no solution exist

Answer: 17.9
Step-by-step explanation:
simplify the above expression, then tell me what rule you used, (product rule, power rule, quotient rule.) then explain how you did the problem
Answer:
Step-by-step explanation:
You have to use the power rule for this. The way I teach my Algebra 1 students to do this is take everything inside the parenthesis and put it into its own set of parenthesis, and then raise each one to the outside power. One thing at a time makes it not so overwhelming. Like this:
[tex](4)^2(x^5)^2(y^3)^2[/tex]
Now follow the power rule. Multiply the power of each element in the parenthesis by the 2 outside.
[tex](4^1)^2=4^2=16[/tex], then [tex](x^5)^2=x^{10[/tex], and finally, [tex](y^3)^2=y^6[/tex].
Now put it all together to get:
[tex]16x^{10}y^6[/tex]
Suppose that the effects of copper on a second species (say, species B) of fish show the variance of ln(LC50) measurements to be .8. If the population means of ln(LC50) for the two species are equal, find the probability that, with random samples of ten measurements from each species, the sample mean for species A exceeds the sample mean for species B by at least 1 unit.
Answer:
Hello the reference related to your question is missing attached below is the reference
answer : p ( x - y ≥ 1 ) = 0.0019
Step-by-step explanation:
Assuming 'X' and 'Y' are independent random samples
X : mean value = [tex]U_{1}[/tex] , variance = 0.4 /10 = 0.04
Y : mean value = [tex]U_{2}[/tex] , variance = 0.8/10 = 0.08
since the values are independent
V [ X - Y ] = V [ X ] + V [Y ] = 0.04 + 0.08 = 0.12
Determine the probability that the sample mean for species A exceeds the sample mean for species B by at least 1 unit
P ( x - y ≥ 1 ) = 0.0019

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.

Answer:
Huh? I'm not sure what you're asking try C
Answer:
B. f(x) = 1/x(x - 2)Step-by-step explanation:
The graphed function has two vertical asymptotes.
The functions A and D have degree 1 on the numerator and degree 2 on the denominator, so finally having degree 1, have one vertical asymptote, therefore discounted.We are left with B and C.
Function B has vertical asymptotes 0 and -2.
This is matching the graph, correctFunction C has vertical asymptotes 0 and 2

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

factor (5a–3b)^2–25a^2 PLS HELP 50 POINTS
Answer:
(-3b) (10a -3b)
Step-by-step explanation:
(5a–3b)^2–25a^2
Replace (5a–3b) with x
x^2 - (5a) ^2
We have the difference of squares
( x-5a) (x+5a)
Now replace x with (5a -3b)
(5a -3b -5a) ( 5a -3b +5a)
Combine like terms
(-3b) (10a -3b)
Answer:
(5a-3b)²-25a²
= 25a²+9b²-2×5a×3b-25a { (a-b)²= a²+b²-2ab}
=9b²-30ab
=3b(3b-10a)

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!
