Answer: a. x=3 or 5

Step-by-step explanation:

x^2-8x+15=0

When factoring this equation we need to find 2 numbers that multiply to get positive (15) and add to get negative (-8)

So -3 and -5 fit this description because -3+-5=-8 and -3*-5=15

(x-3)(x-5)=0

Solve for values of x to get x=3 and x=5

so X=3 or 5

PLEASE HELP!
ELEN [110]

Answer:

Colin's mean score = 17.10

The new mean is 18.00

Step-by-step explanation:

Given scores: 31, 10, 26, 16, 28, 31, 9, 11, 8, 1

number of terms: 10

mean is calculated by given formula = sum of all the data set/ number of terms in the data set.

mean for the 10 scores = (31+ 10+ 26+ 16+ 28+ 31+ 9+ 11+ 8+ 1 )/10

                                       = 171/10 = 17.1

Colin's mean score = 17.10

____________________________________________

runs scored by Colin in 11th match = 27

number of terms: 11

new mean = new sum /number of terms

new mean = (old sum score + 27)/11 = (171+27)/11

new mean = 198/11 = 18

The new mean is 18.00

A group of friends wants to go to the amusement park. They have $94.25 to spend on parking and admission. Parking is $14.75, and
Korvikt [17]

Answer: 6

Step-by-step explanation:

From the question, we are informed that a group of friends wants to go to the amusement park and that they have $94.25 to spend on parking and admission.

We are further told that Parking is $14.75, and tickets cost $13.25 per person, including tax. The equation that can be used to solve the number of people who can go to the amusement park would be:

= 14.75 + 13.25p

Since they've $94.25 to spend, the number of people that can go to the amusement park will be:

14.75 + 13.25p = 94.25

13.25p = 94.25 - 14.75

13.25p = 79.50

p = 79.50 / 13.25

p = 6

6 people can go to the amusement park
