This is the simplified one I didn’t know if you needed it graphed or something
The factor of the function will be (4x - 3) and (3x + 1). The graph of the function is shown below.
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The function is given below.
g(x) = 5x - 12x² + 3
Then the function can be written as
g(x) = - 12x² + 5x + 3
Then the factor of the function will be
g(x) = 0
Then we have
- 12x² + 5x + 3 = 0
12x² - 5x - 3 = 0
12x² - 9x + 4x - 3 = 0
(4x - 3)(3x + 1) = 0
x = -0.33 and 0.75
Then the graph of the equation will be given below.

Step-by-step explanation:
An inspector inspects a shipment of medications to determine the efficacy in terms of the proportion p in the shipment that failed to retain full potency after 60 days of production. Unless there is clear evidence that this proportion is less than 0.05, she will reject the shipment. To reach a decision, she will test the following a large-sample. To do so, she selects an SRS of 200 pills. Suppose that eight of the pills have failed to retain their full potency. The best point estimate for a 95% confidence interval for the true proportion of pills in the shipment that have failed to retain full potency is ___. Round your answer to three decimal places.

We want our exponential function to look like
y = ab^x.
Let a = the initial y-value.
Our initial value is the first number given for f(x). So, a = 3.
Let b = the number that is needed to go from 3 to 6 to 12 to 24 to 48.
We find b by division.
So, b = the next number divided by the previous.
So, b = 6/3 = 2.
We now plug in our values into the general formula above.
y = ab^x

Answers
Answer:
y = 40
Step-by-step explanation:
For #7, we are told that y = 10 when x = 2
We are also told that 'y varies directly as x'. That means there is some constant number, k, so that
Formula --> y = kx
Since y=10 and x= 2, we substitute those numbers into the formula.
We get 10 = k × 2.
So k has to be 5, right?
k = 5
So what is y when x = 8?
Use the formula.
y=kx ---> That gives us y = k × 8. But we know k is 5.
So y = 5 × 8 = 40
y = 40
9514 1404 393
Answer:
7. y = 5x; y = 40
8. y = 1/3x; y = 8/3
Step-by-step explanation:
In the direct proportion equation y=kx, the value of k can be found as ...
k = y/x . . . . . divide both sides by x to solve for k
__
7. k = 10/2 = 5
The equation is ...
y = 5x
For x=8, the value of y is found using the equation:
y = 5(8) = 40
__
8. Same deal, different numbers.
k = 6/18 = 1/3
y = 1/3x . . . . . the equation
y = 8/3 . . . . . y for x=8
What is x?
x/8 + 6 = 4
x=_?
Answers
Answer:x=-16
Step-by-step explanation:
Subtract 6 from both sides
x/8=-2
Multiply the number by 8 on both sides to get x by itself
x=-16
Hope you are having a good day and if you could, brainliest would be nice
to get x alone you have to subtract 6 on both sides giving you x/8=-2 then you multiply 8 on both sides giving you x=-16

In exercises 4-6, a survey reported that 235 of the 500 voters in a sample voted for candidate A and the rest voted for candidate B?
4. What percent of the voters in the sample voted for candidate A? What percent of the voters in the sample voted for candidate B?
5. What is the margin sampling error? Round your answer to the nearest tenth of a percent.
6. For each candidate, give an interval that is likely to contain the exact percent of all voters who voted for the candidate.
7. For #6, can you determine which candidate won? Explain.
Answers
4.
Total voters = 500
Number of voters that voted for candidate A = 235
Number of voters that voted for candidate B = 500 - 235 = 265
Percent of voters that voted for candidate A
= 235
500
× 100%
= 23500
500
= 47%
Percent of voters that voted for candidate B
= 265
500
× 100%
= 26500
500
= 53%
5.
Margin sample error = % of candidate B - 5 of candidate A
= 53% - 47%
= -/+ 6%
Margin sample error = + 6.0% or - 6.0%
6.
Candidate A interval
= 47 ± 0.5
= 46.5% or 47.5%
Candidate B interval
= 53±0.5
= 52.5% or 53.5%
7.
Candidate with the highest percentage win.
Therefore, candidate B won

An appliance salesperson earned $32.80 in commission for selling a refrigerator for $820. At that rate, how much would the salesperson earn in commission for selling a microwave oven for $340?
Answers
340 x 0.04= 13.6 so the commission for the microwave would be $13.60
Answer:
Salesperson would earn $13.6 in commission for selling a microwave oven for $340.
Step-by-step explanation:
We are given that an appliance salesperson earned $32.80 in commission for selling a refrigerator for $820.
We have to find how much would the salesperson earn in commission for selling a microwave oven for $340.
Firstly, we will the find the rate at which the salesperson gets a commission in % terms.
So, Percentage rate of commission is given by;
Rate of commission=(Commission earned ÷ Selling Price of refrigerator) 100
= = = 4%
Now, this rate will be used to find the commission earned on selling a microwave oven for $340, i.e;
Commission earned for selling a microwave oven = 4% of Selling price of microwave oven
= = $13.6
Therefore, salesperson would earn $13.6 in commission for selling a microwave oven for $340.
