Answer:

a)

Step-by-step explanation:

for each point (A, B, C) reduce the 'x-value' by two and reduce the 'y-value' by 7

for example, for point A:

to find A':  (-6, -7) would be (-6-2, -7-7)  which is (-8, -14)

Lines a and b in the figure above are parallel. What is the value of p?
elena-s [515]
It will be c- 20:
4q and 2(q+30) have to equal the same therefore q=30 which makes both these equations equal.
3p + 4q then have to equal 180 as they are on a straight line so you know q=30 so 4x30=120 so 180-120=60
Then 60/3=20 and that is your answer.
Hope this helps :)

Find the missing angle measure.
ycow [4]

Step-by-step explanation:

The sum of all inner angles in the shape should be 540°

(180° for triangles, 360° for squares and other simple 4-corner-shapes, the pattern is the number of corners minus 2 multiplied by 180°)

we can calculate

540-106-94-135=205

so we got 205 degrees for the two unclear corners and one of them has to be 5° greater.

x is 100°

x is 100°x+5 is 105°

(note that in the subtraction part we could have subtracted 5 more and would be left with 2x=200)

A certain large manufacturing facility produces 20,000 parts each week. The manager of the facility estimates that about 1% of t
Slav-nsk [51]

Answer:

198 is the variance for the number of defective parts made each week.      

Step-by-step explanation:

We are given the following in the question:

Number of parts produced each week =  20,000

Percentage of defective parts = 1%

We have to calculate the variance for the number of defective parts made each week.

We treat defective part as a success.

P(Defective part) = 1% = 0.01

p = 0.01

Then the number defective parts follows a binomial distribution .

Formula for variance =

\sigma^2 = np(1-p) = 20000(0.01)(1-0.01) = 198

Thus, 198 is the variance for the number of defective parts made each week.
