Answer:$12,800
Step-by-step explanation:
Add 400 to every n in the equation, I’ll be using y for the “p(n)” part cus it always confuses me like that.
Y=52(400)-0.05 x 400^2
=20,800 - 0.05 x 160,000
=20,800 - 8,000
=12,800
100 people went to a picnic. 32 people got sick with food poisoning. The Public HealthDepartment narrowed it down to either the chicken salad or the cream pie. They determined that80 people ate chicken salad, 75 people ate cream pie, 33 people ate chicken salad cream pie anddid not get sick, 5 ate neither food and did not get sick, 40% of the people who ate chicken saladgot sick, and 36% of the people who are cream pie got sick. Was it the chicken salad or thecream pie
Answer:
It was the chicken salad.
Step-by-step explanation:
If you multiply each amount of people that ate one or the other and how many got sick, you get:
Chicken salad: 32
Cream pie: 27
And 32 people got sick so it must be the chicken salad.

A publisher reports that 40% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 200 found that 31% of the readers owned a particular make of car. Determine the P-value of the test statistic. Round your answer to four decimal places.
Answer:
[tex]p-value = 0.9953[/tex]
Step-by-step explanation:
Given
[tex]P = 40\%[/tex] --- proportion of population
[tex]n = 200[/tex] -- samples
[tex]p = 31\%[/tex] -- proportion of samples
Required
Determine the p value
First, calculate the standard deviation ([tex]\sigma[/tex])
[tex]\sigma = \sqrt{\frac{P*(1 - P)}{n}}[/tex]
[tex]\sigma = \sqrt{\frac{40\%*(1 - 40\%)}{200}}[/tex]
[tex]\sigma = \sqrt{\frac{0.40*(1 - 0.40)}{200}}[/tex]
[tex]\sigma = \sqrt{\frac{0.40*0.60}{200}}[/tex]
[tex]\sigma = \sqrt{\frac{0.24}{200}}[/tex]
[tex]\sigma = \sqrt{0.0012}[/tex]
[tex]\sigma = 0.0346[/tex]
Next, we calculate the z score
[tex]z = \frac{p - P}{\sigma}[/tex]
[tex]z = \frac{40\% - 31\%}{0.0346}[/tex]
[tex]z = \frac{9\%}{0.0346}[/tex]
[tex]z = \frac{0.09}{0.0346}[/tex]
[tex]z = 2.6012[/tex]
[tex]z \approx 2.60[/tex]
From the z table, the p value of [tex]z = 2.60[/tex] is: 0.9953
Hence:
[tex]p-value = 0.9953[/tex]
Solve w=3/7(ay+m) for y
Answer:gd
Step-by-step explanation:
Vygfy
Answer:
y = (7w - 3m) / 3a
Step-by-step explanation:
w = 3/7ay + 3/7m
multiply each side by 7 to eliminate fractions
7w = 3ay + 3m
3ay = 7w - 3m
y = (7w - 3m) / 3a

A pet store has 9 puppies, including 2 poodles, 2 terriers, and 5 retrievers. If Rebecka and Aaron, in that order, each select one puppy at random with replacement (they may both select the same one), find the probability that Rebecka selects a terrier and Aaron selects a retriever.
Answer:
5/162
Step-by-step explanation:
Probability of getting terrier = 2/18 = 1/9
Probability of getting retriever = 5/18
5/18 x 1/9 = 5/162

Enter the value for x that makes the equation true.
Answer:
Step-by-step explanation:
⅔(x-6) = ¾(x+16)
Multiply both sides by 12
8(x-6) = 9(x+16)
8x - 48 = 9x + 144
x = -192

Step-by-step explanation:
✔️Rate of change using two points on the line, say (2, 60) and (3, 75);
Rate of change (m) = ∆y\/∆x = (75 - 60) / (3 - 2) = 15/1
Rate of change = 15
This means each class costs $15
✔️Initial value is the y-intercept (b). It represents the initial start-up fee.
To find initial value/y-intercept (b), substitute m = 15 and (x, y) = (2, 60) into y = mx + b.
Thus:
60 = 15(2) + b
60 = 30 + b
60 - 30 = b
30 = b
b = 30
Therefore, initial start-up fee is $30.
At the organic produce store you can buy 3 bags of sweet potatoes for $20.07.
How much would it cost if you were to buy only 2 bags.
Answer:
$13.38
Step-by-step explanation:
Use proportions to solve this problem:
$20.07 / 3 bags = X / 2 bags
multiply both sides by "2 bags" to isolate the unknown X
$20.07 * 2 / 3 = X
Therefore, X = $13.38

A student wrote the following equation for the graph: y = -3/2 - 4. This is incorrect. What is the mistake? What is the correct equation?
Answer:
y=6
Step-by-step explanation:
y= -3/2(-4) : y=4
y=-2 3/4(-4)
y=3/2. 4
y= 3×4/2
y =12/2
12/2 =6
y =6
out of 75/6 is 72%. (Write as a fraction in simplest form.)
Answer:22%
Step-by-step explanation:
The simplest form of the total of 75/6 would be 432 / 7500.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100. Suppose the value of which a thing is expressed in percentage is "a' Suppose the percent that considered thing is of "a" is b%
Then the percent; per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Given that out of 75/6 is 72%.
Therefore, it will be written as;
x of 75/6 = 72%.
We need to find the value of total x.
x of 75/6 = 72%.
x × 75/6 = 72%
x × 75/6 = 72/100
Cross multiplication;
x = 72/100 × 6/75
x = 432 / 7500
x = 0.0576
Hence, the simplest form of the total of 75/6 would be 432 / 7500.
