3 0

Answer:

Step-by-step explanation:

Δ = 4^{2}  - 4 * 4 * (-63)  =  16 + 16 * 63 = 16 * (1 + 63) = 16 * 64

VΔ = 4 *  8 = 32

a = (- 4 ± 32) * \frac{1}{8}

a' = 7/2

a''= 9/2

The spinner at the right is divided into eight equal parts. Find the theoretical probability of
finlep [7]

Answer:

\frac{3}{4} probability of landing on a number greater than 2 on the spinner.

Step-by-step explanation:

A theoretical probability is given by the number of desired outcomes divided by the number of total outcomes.

In this question:

8 possible outcomes(all numbers from 1 to 8).

6 desired outcomes(3, 4, 5, 6, 7 and 8, that is, all the numbers greater than 2). So

p = \frac{6}{8} = \frac{3}{4}

\frac{3}{4} probability of landing on a number greater than 2 on the spinner.

Isabel received 4/7 of the 210 votes for cast for class treasurer. How many votes did she receive? Write your answer in simplest
KengaRu [80]

Answer:

120 votes

Step-by-step explanation:

So one way to solve this is by creating an equation to solve for x.

So we are given 4/7, that will be one side of the equation.  

And we are trying to figure out how many votes out of the 210 she received, so on the other side of the equation we will have x/210, since we are solving for x.  

So 4/7 = x/210

We want to get x alone, so we can multiply 4/7 by 210, which equals 120.

So x equals 120!
