Answer:
z = -6
Step-by-step explanation:
5z + 2 = 3z - 10
Subtract 3z from both sides
2z + 2 = -10
Subtract 2 from both sides
2z = -12
Divide each side by 2
z = -6
So, the answer is z = -6
Hey there,
Both

= 85 and

are 80°.
1.) First off, the reason why there would be 80° would be because by looking at this angel, this angel is a obtuse angel. And also, it is also close to being a (right angel). And a right angel is 90°. So this is a clue that it would be around there.
2.) The area of this figure would be 300°.So in order to find the other angel's, we would have plug in both <em>x =85 and also y=80.
</em>Hope this helps.

Answer:
An appliance manufacturer gives a warranty, and 95 percent of its appliances do not require repair before the warranty expires. An organization buys 10 of these appliances. Calculate an interval that contains 95.44 percent of all the appliances that will not require repair.
A. [8.12, 10.88]
B. [7.43, 11.57]
C. [8.81, 10.19]
D. [8.55, 10.45]
Step-by-step explanation:
We can calculate the confidence interval for a proportion p = 0.95 and a sample size n = 10.
Note that the critical value for 95.44% confidence is 1.9991. Z-score table.
Between 81.22% and 108.78% of 10 units is 8.12 and 10.88 units. Therefore the confidence interval is: (8.12, 10.88).
Answer: [ 8.12 , 10.88 ]
Step-by-step explanation:
So you add one over the other
3x-2y=7
-3x+5y=5
=
3y=12
Then you divide 3 from both sides
(3y)/3=12/3
y=4
Then you substitute the y=4 in to the equation of your choice
3x-2(4)=7
3x-8=7
3x-8=7
+8 +8
3x=15
x=5
Answer: tis C
Step-by-step explanation:
x^2/x^2*z^2/y^-2
=1*z^2/y^-2
=z^2y^2
=y^2z^2
