Using it's concept, it is found that there is a 0.625 = 62.5% probability that an individual owns a stock.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, out of 200 graduates, 35 + 90 = 125 of them own stocks, hence:

p = 125/200 = 0.625.

There is a 0.625 = 62.5% probability that an individual owns a stock.

What is 35.125 as a mixed number??
Sever21 [200]
The number can be separated into 35+0.125
0.125 can be rewritten as,
\frac{125}{1000}
So, the number can be rewritten;
35+\frac{125}{1000}
35\frac{125}{1000}

Find the equation of the parabola that has zeros of x = –1 and x = 3 and a y-intercept of (0,–9). Question 1 options: A) y = 3x2
andrey2020 [161]

Answer:

A

Step-by-step explanation:

Given the zeros are x = - 1 and x = 3 then the factors are

(x + 1) and (x - 3) and the parabola is the product of the factors, that is

y = a(x + 1)(x - 3) ← where a is a multiplier

To find a substitute (0, - 9) into the equation

- 9 = a(0 + 1)(0 - 3) = a(1)(- 3) = - 3a ( divide both sides by - 3 )

3 = a, thus

y = 3(x + 1)(x - 3) ← expand the factors using FOIL

  = 3(x² - 2x - 3) ← distribute by 3

  = 3x² - 6x - 9 → A

Need help also if you can can you do it step-by-step explanation please thank you 3(c + 8) = 28<br>​
skelet666 [1.2K]

Answer:

c = 4/3

Step-by-step explanation:

3(c + 8) = 28

Since we have paranthesis, first use the dsitributive property [multiply 3 by c and 8]

3(c + 8) = 28

3c + 24 = 28

To find the value of c, you must have c alone on one side, so subtract 24 from both sides

3c + 24 = 28

3c = 4

Now, divide by 3 to both sides to get your answer

3c = 4

c = 4/3

Therefore, the answer is 4/3!

I hope this helps! :)
