Answer:
x= 90 degrees because AD is the perpendicular bisector and the angle bisector
y=86 degrees because 47+47+86=180
Step-by-step explanation:
Answer:
310
Step-by-step explanation:
Use the Order of Operations method. (P.E.M.D.A.S.)
Our expression: 3+2⋅4+62⋅5−1
<u>Multiply 62 and 5, and 2 and 4:</u>
3+8+310-1
<u>Add and Subtract from left to right:</u>
11+310-1
311-1
310
Answer:
So the value of the test statistic is -0.85.
Step-by-step explanation:
We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.
We get that:

We calculate the standar deviation:

We calculate the value of the test statistic:

So the value of the test statistic is -0.85.
Answer: The two sides are 15m and 10m.
Step-by-step explanation:
Area = l x w
150 = l x w
There are two solutions for l
l 1= P/4+1/4√P2﹣16A
=50/4+1/4·√50^2﹣16·150=15m
l2 = P/4﹣1/4√P2﹣16A
=50/4﹣1/4·√50^2﹣16·150=10m
