5 0

Answer:

13 / 8000

Step-by-step explanation:

Given:

Total number of Spark plugs = 8,000

Total number of defective Spark plugs = 13

Probability of defective spark plug =?

Computation:

Probability of happening an event (P.e) = Number of favorable outcomes / Total Number of outcomes

= 13 / 8000

Therefore, Probability to get a defective spark plug is 13/8000

By multiplying integers what is the total of (-10)(0)
34kurt

Anything multiplied by 0 is zero. 100000 * 0 = 0, -1000 * 0 = 0.


Therefore, (-10)(0) = 0.

A 26 ft long ramp is used to reach 10 ft up a wall. The ramp covers a horizontal distance of 24 ft. To make the ramp less steep,
Anika [276]

Answer:

The length of new ramp is 49.03 ft.

Step-by-step explanation:

It is given that 26 ft long ramp is used to reach 10 ft up a wall. The ramp covers a horizontal distance of 24 ft.

If the horizontal distance is doubled, then the horizontal distance is 48 ft. The height remains same. Therefore the height of ram is 10 ft.

Use pythagoras in new right angle triangle.

hypotenuse^2=base^2+perpendicular^2

(AE)^2=(AD)^2+(ED)^2

(AE)^2=(48)^2+(10)^2

(AE)^2=2304+100

AE=\sqrt{2404}

AE=49.0306027\approx 49.03

Therefore the length of new ramp is 49.03 ft.

Find the value of c and YZ if Y is between X and Z. X Y = 5 . 5 , Y Z = 2 c , X Z = 8 . 9
e-lub [12.9K]

The measure of YZ is 3.4 cm and the measure of c is 1.7 cm.

Given that, Y is between X and Z. XY = 5.5 , YZ = 2c , X Z= 8.9.

We need to find the value of c and YZ.

<h3>What is a line segment?</h3>

A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions. In this lesson, we will learn more about a line segment, its symbol, and the way to measure a line segment.

Now, YZ=XZ-XY

⇒2c=8.9-5.5

⇒2c=3.4 cm

⇒c=1.7 cm

Therefore, the measure of YZ is 3.4 cm and the measure of c is 1.7 cm.
