Answer: second option
Step-by-step explanation:
The standard form of a quadratic equation is:

Then, to write the quadratic equation given in the problem in standard form, you must substract 1 from both sides of the equation. Then you have:

Given the quadratic equation above, to find the value of
you must substitute:
a=2; b=5 and c=-1 into
Thenrefore, you obtain the following result:

$201.19-16.95= 184.24 184.24/.94= 196

Answer:
6.52 x 10^3 is just basically 6.52 × 1000, which is 6520. But 652,000 ÷ 10^2 is just 652000 ÷ 100, which is 6520. That's why they have the same answer.
Answer: Bert's salary didn't increase while Ernie's salary increased by 11 percent.
Step-by-step explanation:
645 / 580 = 1.11
Simple:
1.11 * 100 = 111
100 is a whole so we subtract 100 from 111 to get 11.
11% is our answer.
It doesn't look like Bert's salary changed, 520 =/ 520

<u>Step-by-step explanation:</u>
The total frequency is 33+30+18+21+42+6 = 150. This means they ran the experiment 150 times. The probability (P) is calculated by the satisfactory number of outcomes (frequency) divided by the total number of experiments/outcomes (total frequency):
