Find the equation of a parabola with a vertical axis and its vertex at the origin and passing through the point (-2, 3).
Answer:
[tex]y=\frac{3}{4}x^2[/tex]
Step-by-step explanation:
Hi there!
Because we're given the vertex of the parabola, we can determine its equation in vertex form:
[tex]y=a(x-h)^2+k[/tex] where the vertex is [tex](h,k)[/tex]
Plug in the vertex (0,0)
[tex]y=a(x-0)^2+0\\y=a(x)^2\\y=a(x-0)^2+0\\y=ax^2[/tex]
Now, we must solve for a. Plug in the given point (-2,3) and solve for a:
[tex]3=a(-2)^2\\3=4a\\\frac{3}{4} =a[/tex]
Therefore, the value of a is [tex]\frac{3}{4}[/tex]. Plug this back into [tex]y=ax^2[/tex]:
[tex]y=\frac{3}{4}x^2[/tex]
I hope this helps!

The mean number of words per minute (WPM) read by sixth graders is 84 with a standard deviation of 15 WPM. If 188 sixth graders are randomly selected, what is the probability that the sample mean would differ from the population mean by greater than 1.46 WPM
Answer:
0.1836 = 18.36% probability that the sample mean would differ from the population mean by greater than 1.46 WPM
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
The mean number of words per minute (WPM) read by sixth graders is 84 with a standard deviation of 15 WPM.
This means that [tex]\mu = 84, \sigma = 15[/tex]
Sample of 188
This means that [tex]n = 188, s = \frac{15}{\sqrt{188}}[/tex]
What is the probability that the sample mean would differ from the population mean by greater than 1.46 WPM?
Greater than 84 + 1.46 = 85.46 or less than 84 - 1.46 = 82.54. Since the normal distribution is symmetric, these probabilities are equal, so we find one of them and multiply by 2.
Probability is is less than 82.54.
P-value of Z when X = 82.54. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{82.54 - 84}{\frac{15}{\sqrt{188}}}[/tex]
[tex]Z = -1.33[/tex]
[tex]Z = -1.33[/tex] has a p-value of 0.0918
2*0.0918 = 0.1836
0.1836 = 18.36% probability that the sample mean would differ from the population mean by greater than 1.46 WPM

if 125 men can do a piece of work in 120days, how many men would be sufficient to do the same work in 100days?
Answer:
x =150 men
Step-by-step explanation:
Think of the total as workdays
125men* 120days = 15000 workdays
We still need 15000 workdays
100 days * x = 15000workdays
Divide by 100
x = 15000/ 100
x =150 men
Answer:
150 men
Step-by-step explanation:
120 × 125 = 15000
15000 ÷ 100

An experiment has three steps with three outcomes possible for the first step, two outcomes possible for the second step, and five outcomes possible for the third step. How many experimental outcomes exist for the entire experiment
Answer:
30 experimental outcomes exist for the entire experiment.
Step-by-step explanation:
Fundamental counting principle:
States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.
In this question:
Three outcomes possible for the first step.
Two for the second step.
Five for the third step.
How many experimental outcomes exist for the entire experiment?
Steps are independent, so, by the fundamental counting principle:
3*2*5 = 6*5 = 30
30 experimental outcomes exist for the entire experiment.

Which of the following is the inverse of F(x) if F(x) = 6x?
O A. F(x) = 6x
O B. F(x) = x-6
O C. F(X) -
O D. F(x) = x + 6
The correct inverse of F(x) = 6x is y = x/6 according to given question
To find the inverse of a function, we need to interchange the roles of the dependent variable (x) and the independent variable (F(x)) and solve for the new dependent variable.
Given that F(x) = 6x, to find the inverse, we can follow these steps:
Replace F(x) with y: y = 6x.
Swap x and y: x = 6y.
Solve for y: Divide both sides by 6 to isolate y: y = x/6.
Therefore, the inverse function of F(x) = 6x is given by y = x/6.
Out of the options provided:
A. F(x) = 6x: This is the original function, not the inverse.
B. F(x) = x-6: This is not the correct inverse function.
C. F(X): This option is incomplete; it does not provide an equation for the inverse.
D. F(x) = x + 6: This is not the correct inverse function.
Therefore, the correct inverse of F(x) = 6x is y = x/6.

Kevin entered a pie eating contest. He ate 4 pies in 132 seconds. What is kevins unit rate? Awnser without units.
Answer:
Kevin eats 1 pie for every 33 seconds that pass
Step-by-step explanation:
A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.
If we were wondering how many seconds Kevin takes to eat a pie then the equation would look like:
132 seconds / 4 pies = 33 seconds per pie
33 seconds / 1 pie
However, if we were looking for how many pies Kevin eats in a second, then the equation would look like:
4 pies / 132 = .0303 or 3.03% of a pie per second
.0303 pies / 1 second

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 378 people entered the park, and the admission fees collected totaled 1,042.00 dollars. How many children and how many adults were admitted?
Answer:
188 children, 190 adults
Step-by-step explanation:
For this equation, let c be the number of children, and a represent the number of adults.
On this day 378 total people were at the park, so
a + c = 378 eq 1
Each adult pays $4, so the admission fee for ALL adults will be $4 multiplied by the number of adults , a, so 4a
Use the same method for the children, and the total all children paid is 1.50c
From all the children and adults, the total was 1042, so merge the 2 cost variables together.
4a + 1.50c = 1042 eq 2
the 2 equations we will use are
a + c = 378
4a + 1.50c = 1042
From equation 1, subtract c from both sides, and
a = 378 - c eq 3
Substitute the value of a in eq 3 into equation 2
4a + 1.50c = 1042
4 (378 - c) + 1.50c = 1042
1512 - 4c +1.50 c = 1042 (collect like terms)
1512 - 1042 = 4c -1.50 c
470 = 2.5 c
c = 470 /2.5
c = 188 children
Substitute the value of c into eq 3 to get the value of a
a = 378 -c
a = 378 - 188
a = 190 adults

Its very simple. So were saying that y is 8. 2x+24=12. Which is 2x=12-24. Which is 2x=-12. Which is x=-6. So if x is -6 when y is 8, then the value must be equal to -6. You just have to find a way to put it into the ordered pair (4_,8)...
