Answers
Answer:
B. 4^15*5^10
Step-by-step explanation:
First you can take the out-out-outside exponent and "pass it out" to both the numerator and the denominator. When you have a power raised to a power, you MULTIPLY the exponents. See image.
Next you can "fix" a negative exponent by pushing it across the fraction bar. As it passes across the fraction bar, the exponent changes sign. So the -10 exponent on the bottom, becomes a positive 10 exponent on top. See image.

Pedro owns a shrimp truck near the beach. he sells garlic shrimp for $8 a plate and spicy shrimp for $6 a plate. each day pedro stocks enough shrimp to sell at most 120 plates total, but he would like to earn at least $800. which combination of garlic shrimp plates and spicy shrimp plates can pedro sell to meet his goal?
Answers
Pedro can sell enough by combining the sales of 40 plates of garlic shrimp and 80 dishes of spicy shrimp to reach his objective.
As a resultNear the shore, Pedro runs a shrimp delivery business.
He offers spicy shrimp for $6 a plate and garlic shrimp for $8 per plate.
Pedro wants to make at least $800 per day but only stocks enough shrimp to sell a maximum of 120 plates.
We need to ascertain,
Which dish combining hot shrimp and garlicky shrimp can Pedro sell to reach his objective?
In response to the query,
Let's sell the x dishes of garlic shrimp.
And plates of hot shrimp were sold.
Pedro has 120 dishes' worth of shrimp in stock each day.
Then,
Shrimp sold daily total is equal to the sum of plates of garlic shrimp and spicy shrimp.
X + Y = 120
Furthermore, He offers $6spicy and $8garlic shrimp, per plate.
To make at least $800 is what he wants to do.
Then,
the sum of the price of the spicy shrimp per plate and the price of the garlic shrimp per plate,
8X + 6Y = 800
When the two equations are solved,
X + Y = 120
8X + 6Y = 800
From equation 1,
Y = 120 - X
In equation 2, replace x with its value.
8X + 6Y = 800
8(120 - Y) + 6Y = 800
960 - 8Y + 6Y = 800
- 2Y = - 160
Y = 160/2
Y = 80
In equation 1, replace y with its value.
X + Y = 120
X + 80 = 120
X = 120 - 80
X = 40
In order to achieve his objective, Pedro sold a combination of 40 plates of garlic shrimp and 80 dishes of spicy shrimp.

In a survey, the planning value for the population proportion is . How large a sample should be taken to provide a confidence interval with a margin of error of
Answers
The value of sample size n in this statement according to a confidence interval is 350.
According to the statement
we have a given that the value of error and population proportion and we have to find the value of sample size.
So, we know that the
confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Here
p represent the real population proportion of interest
ρ represent the estimated proportion for the sample
n is the sample size required (variable of interest)
z represent the critical value for the margin of error
So, The population proportion have the following distribution
P≈n ( p, ([p (1-p)]/n)^1/2)
Here In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95% of confidence, our significance level would be given by α = 1 - 0.95 = 0.05
and α/2 = 0.025 And the critical value would be given by:
z = 1.96
And on this case we have that ME = ±0.05 and we are interested in order to find the value of n, if we solve n from equation (a) we got the value
n = 0.35(1-0.35) / (0.05/1.96)^2
so, the value becomes
n = 350.
So, The value of sample size n in this statement is 350.

A manufacturer must test that his bolts are 4.00cm long when they come off the assembly line. He must recalibrate his machines if the bolts are too long or too short. After sampling 81 randomly selected bolts off the assembly line, he calculates the sample mean to be 3.97cm. He knows that the population standard deviation is 0.14cm. Assuming a level of significance of 0.01, is there sufficient evidence to show that the manufacturer needs to recalibrate the machines
Answers
The p-value(0.0538) is greater than the given significance level of 0.01. So, there is no sufficient evidence to show that the manufacturer needs to recalibrate the machines.
What is the test statistics formula for finding the p-value approach of hypothesis testing?The test statistics formula for finding the z-score is,
z = (X - μ)/(σ/√n)
Where,
X = sample mean
μ = population mean
σ = population standard deviation
n = sample size
With this z-score, the p-value is calculated. If p > α, then the null hypothesis is not rejected, and if p < α, then the null hypothesis is rejected.
Calculation:It is given that,
The population mean μ = 4.00
The sample size n = 81
The sample mean X = 3.97
The standard deviation σ = 0.14
and the significance level α = 0.01
So, the hypothesis is:
The null hypothesis: H0: μ = 4
The alternative hypothesis: Ha: μ ≠ 4
Thus, the test statistic value is,
z = (X - μ)/(σ/√n)
= (3.97 - 4)/(0.14/√81)
= - 0.03/0.015
= -1.928
So, for z = -1.928, the p-value is 0.053855
Since p > 0.01, there is no sufficient evidence to show that the manufacturer needs to recalibrate the machines.

The number of teams that can be made can be determined by dividing the total number of friends by the total number of players in each team. The whole number that is derived from the division process is the number of teams teams that can be made given the total number of friends and the number of people that have to be in each group.

The answers are :
A) y = -5x + 64
B) -1
Part (A) :
Finding the slope : Take the points (6, 34) and (10, 14)
m = Δy/Δx
m = 14 - 34 / 10 - 6
m = -20/4
* m = -5 *
Using point slope formula to find equation :
y - y₁ = m (x - x₁)
y - 34 = -5 (x - 6)
y - 34 = -5x + 30

y = -5(13) + 64
y = -65 + 64
