125+42= 167
180-167= 13 degrees
Triangles is always equaled to 180 degrees.
Answer: choice 3
I am pretty sure this is the answer
Unit rate would be 50 because 250÷5=50, so the answer would be (250×3)+50, witch is 800.
Answer:
4g-5p i think
Step-by-step explanation:
7g-3g=4g
4p-9p=-5p
So Sahra is 3 times as old as her daugter. That means that the sum of their age is the daughters age times 4.
We can prove that by saying the daughters age is x. Sahra's age must be 3x. Their sum must be x+3x = 4x.
So to get the daughters age we divide the sum by 4, which is 8.
Answer:
The z-distribution should be used for this problem.
Step-by-step explanation:
The population distribution is assumed to be normal. Which distribution to use?
If we have the standard deviation for the sample, we use the t-distribution.
If we use the standard deviation for the population, we use the z-distribution.
There is a known standard deviation of 2.2 minutes.
This means that 2.2 is the population standard deviation, and thus, the z-distribution should be used for this problem.
