When registering their cars, owners must identify the color that covers the largest portion of the vehicle. In one region, the probability that car was mainly white was 0.24, the probability that it was mainly silver was 0.22, and the probability that it was mainly black was 0.19. In this region, are the events "silver" and "black" mutually exclusive:? Choose 1 answer A) Yes
B) No
Find the probability that a randomly selected car from this region is mainly silver OR mainly black.
P (silver OR black)=

Answers

Answer 1

Answer:

Answer:

A) Yes

Step-by-step explanation:

Yes, the events silver and black are mutually exclusive, meaning they cannot not happen at the same time. While a car can certainly be black and silver, a car cannot be mainly silver AND mainly black at the same time. One color is going to be dominant

P (silver OR black)= P(silver) + P(black)

= 0.22 + 0.19

= 0.41

55 is 40% of what number

Answers

It is important to do thecalculations very carefully. Otherwise there is nothing complicated about thisproblem.
Let us assume the unknown number = x
Then
40x/100 = 55
40x = 55 * 100
40x = 5500
x = 5500/40
= 550/4
= 137.5
So55 is 40% of 137.50. I hope the procedure is clear to you and in futureyou can solve such problems on your own without requiring any help fromoutside.This is the simplest way of solving suchproblems.

55 is 40% of 137.5

Convert your percentage into a decimal:
40%/100 = 0.4

Divide 55 by the decimal:
55 ÷ 0.4 = 137.5

The graph of y = x 2 has been translated 7 units to the left. The equation of the resulting parabola is _____.

Answers

Answer:

$y = (x+7)^2$

Step-by-step explanation:

Horizontal translation:

if y =f(x) , then y = f(x+h) is horizontal translation.

The translation h moves the graph to the left when h is the positive value and to the right when h is negative.

As per the statement:

Given the graph:

$y=x^2$

It has been translated 7 units to the left

By definition:

h = 7 units > 0

then, the equation becomes;

$y = (x+7)^2$

Therefore, the equation of the resulting parabola is, $y = (x+7)^2$

Assuming you meant the equation y=x^2, the translated equation would be Y=(x+7)^2
