The probability that a new spark plug is defective is 0.06. You need two new spark plugs. What is the probability that both spark plugs you buy are defective?A) 0.06
B) 0.12
C) 0.0036
D) 0.0030

Answers

Answer 1
Answer:

Answer:

Option C - 0.0036

Step-by-step explanation:

Given : The probability that a new spark plug is defective is 0.06. You need two new spark plugs.

To find : What is the probability that both spark plugs you buy are defective?

Solution :

Probability of one spark plug being defective is 0.06

We have to find for two defective spark plugs.

This situation is a compound event in which there is more than one possible outcome.

So, The Probability of two spark plug being defective is

P=0.06* 0.06

P=0.0036

Therefore, The Probability of two spark plug being defective is 0.0036.

So, Option C is correct.

The angle measures of triangle ABC are given• The measure of angle A is (2x – 10)
• The measure of angle B is 70°
• The measure of angle Cis (4x)
What is the value of x?

Answers

The measure of the value x of the triangle is x = 20.

Given data:

In a triangle, the sum of the angles is always 180 degrees. Therefore, we can set up an equation using the given angle measures:

Angle A + Angle B + Angle C = 180

Substitute the given angle measures:

(2x - 10) + 70 + 4x = 180

Combine like terms:

6x - 10 + 70 = 180

Simplify:

6x + 60 = 180

Now, subtract 60 from both sides of the equation:

6x = 120

Finally, divide both sides by 6 to solve for x:

x = 20

Hence, the value of x is 20 and the angles are solved.

x is equal to 20.

The angles of one triangle always add up to 180°, so we can add the measures of each angle together and make an equation.

equation —> 2x - 10 + 70 + 4x = 180

After combining like terms, we get 6x + 60 = 180.

Then we can subtract 60 from both sides to isolate the variable, and the equation becomes 6x = 120. Then we can divide both sides by 6 to get the value of x. The equation becomes x = 20.

Answers

x^2+y^2-18x-2y+82=64 = (x-9)^2 + (y-1)^2 = 64 = 8^2

Center (9 , 1 )  radius = 8

A rental car costs $48 for one day plus an additional $0.52 per mile. If you have $110, how many miles can you drive the car?

Answers

Answer:

2.27 miles is the answer.

Step-by-step explanation:

Money needed = $48+$0.52 = $48.52

So,

$48.52 = 1 mile

$1 = 1/$48.52

$110 = (1/$48.52)×$110

= 2.27 miles
