Answer: second option

Step-by-step explanation:

The standard form of a quadratic equation is:

ax^2+bx+c=0

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:

2x^2+5x-1=0

Given the quadratic equation above, to find the value of b^2-4ac  you must substitute:

a=2; b=5 and c=-1 into b^2-4ac

Thenrefore, you obtain the following result:

5^2-4(2)(-1)=33

Why do 6.52 x 10^3 and 652,000 ÷ 10^2 have the same answer?
Kisachek [45]

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.

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Viktor [21]

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

Answer: 0) 0.22

              1) 0.20

              2) 0.12

              3) 0.14

              4) 0.28

              5) 0.04

<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):

\begin{array}{c|c||lc}\underline{x}&\underline{f}&\underline{f\div 150}&\underline{\text{P}}\\0&33&33\div 150=&0.22\\1&30&30\div150=&0.20\\2&18&18\div 150=&0.12\\3&21&21\div 150=&0.14\\4&42&42\div 150=&0.28\\5&6&6\div 150=&0.04\end{array}\right]
