What is the measure of angle 1

Mathematics
1 answer:
SIZIF [17.4K]3 years ago
3 0

Answer:

Angle 1 is 75 degrees (c) & Angle 2 is 105 degrees (e)

Sum of 6 & 7 is 180

Step-by-step explanation:

75 degrees is directly across from angle 1, meaning they are the same. These are <em>vertical angles</em>.

Angle 2 & 75 degrees are <em>supplementary angles</em>, meaning they add up to 180 degrees.

Knowing that, we can do 180 - 75 = 105

6 & 7 are also <em>supplementary</em>, meaning that they are equal to 180 (a straight line).

Hope this helped. :)

Solve -9-8(1+4h)=-17
Mariulka [41]
-9-8(1+4h) = -17. We need to solve for h.
First, use the distributive property for 8(1+4h):
8(1+4h) = 8*1 + 8*4h = 8 + 32h

So -9-8(1+4h) = -17
-9 - (8+32h) = -17
-9 - 8 - 32h = -17
-17 - 32h = - 17
Add 17 on both sides to have the variables on a side and the numbers on the other:
-17 - 32h + 17 = -17 + 17
-32h = 0
divide both sides by -32 to get the variable h alone and its value on the other side:
(-32h)/-32 = 0/-32
h = 0.

So -9-8(1+4h) = -17 for h = 0.

You can recheck your answer (very important):
-9 - 8(1+4h) = -9 -8(1+4*0) = -9 - 8(1+0) = -9-8*1 = -9-8 = -17
The answer has been approved.

Hope this Helps! :)

The scores of 1000 students on a standardized test are normally distributed with a mean of 50 and a standard deviation of 5. wha
ra1l [238]
We are looking to find P(X>60 students)

X is normally distributed with mean 50 and standard deviation 5

We need to find the z-score of 60 students 
Z= \frac{60-50}{5}=2

To find the probability of P(Z>2), we can do 1 - P(Z<2)
So we read the probability when Z<2 which is 0.9772, then subtract from one we get 0.0228

The number of students that has score more than 60 is 0.0228 x 1000 = 228 students
