A triangle cannot have two right angles because the sum of all three angles of a triangle is 180. If there were two right angles in a triangle, then the two angles themselves would equal to 180 degrees, without adding the third angles. Since the degrees added up would have to equal 180 and with two right angles it would be more than 180, there cannot be two right angles in a triangle.

The lifespan of a 60-watt lightbulb produced by a company is normally distributed with a mean of 1450 hours and a standard devia

Flura [38]

To evaluate the probability that the lifespan will be between 1440 and 1465 hours will be given by:
P(1440<x<1465)
using the z-score formula we obtain:
z=(x-μ)/σ
where:
μ=1450
σ=8.5
hence
when x=1440
z=(1440-1450)/8.5
z=-1.18
P(z<-1.18)=0.1190

when x=1465
z=(1465-1450)/8.5
z=1.77
P(z<1.77)=0.9625

hence:
P(1440<x<1465)
=0.9625-0.1180
=0.8445

Wrote and solve an equation that will help you find three consecutive even numbers that sum to 600

vladimir1956 [14]

Answer:

198, 200 and 202

Step-by-step explanation:

Represent the three consecutive even numbers by x, x + 2, x + 4.

Then:

x + x + 2 + x + 4 = 600

Combining like terms, we get:

3x = 594, so:

x = 198

x + 2 = 200

x + 4 = 202

The three consecutive even numbers are 198, 200 and 202.

If a triangle has one side with a length of 10 meters and a second side with a length of 14 meters, what are possible lengths of

Olin [163]

Step-by-step explanation:

The sum of the lengths of any two sides of a triangle is greater than the length of third side

as sum of two sides is 24 so the lenght of 3rd side will be less than 24
