Answer:
∠CDF= 70°
Step-by-step explanation:
there's an easier way to do this which is adding the angles ∠EDG and ∠GDF and then subtracting that from 180° but, checking your work in the same process is a little more work.
First, I'd like to find ∠ADB.
- 85°+70°= 155°
- 180°-155°= 25°
- ∠ADB= 25°
Second, add all the angles together.
- 70°+50°+60°+85°+25°= 290°
- 360°-290°= 70°
-14/8
No option is right

Answer: 1.25
Step-by-step explanation:
Given: A college-entrance exam is designed so that scores are normally distributed with a mean
= 500 and a standard deviation
= 100.
A z-score measures how many standard deviations a given measurement deviates from the mean.
Let Y be a random variable that denotes the scores in the exam.
Formula for z-score = 
Z-score = 
⇒ Z-score = 
⇒Z-score =1.25
Therefore , the required z-score = 1.25
Answer:
k
Step-by-step explanation:
The last awnser is 15x + 2 and the first one is explained below:
