balandron [24]

Answer:

The probability is 0.47.

Step-by-step explanation:

Given,

Total number of people who walked by his store = 128,

Out of these people the number of people who came into the store = 60,

Hence, the probability that a person who walks by the store will enter the store

$=\frac{\text{People who came in store}}{\text{People who walked by store}}$

$=\frac{60}{128}$

$=0.46875$

$\approx 0.47$

What is the value of z? Enter your answer in the box.

Georgia [21]

Answer:

Step-by-step explanation:

Because the angles of a triangle always add up to 180°, you can set up an equation like this.

$62+95+z=180$

$157+z=180$

$157-157+z=180-157$

$z=23$

How do I solve question 5?

Nezavi [6.7K]

A) x^2 + y^2 = 80
B) x * y = 12

What is x^2 -y^2?
B) x * y = 12
So y = 12 / x
A) x^2 + (12/x)^2 = 80
x^2 + (12/x)^2 = 80
x^2 + (144/x^2) = 80
Multiplying each side by x^2
x^4 + 144 = 80x^2
x^4 -80x^2 + 144 = 0
X = 1.355 (found by trial and error)
Y = 8.85608 (found by trial and error)
