GEOMETRY PROBLEMS PLEASE HELP ME

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

Answer:

12) The measure of PQR is 36 since both angles MQP (25) and PQR should add up to MQR (61)

13) The graph shows that both angles are congruent so that means:

2x+8= x+22

2x= x+14

x=14

14) angle ADB and angle BDC since it shows that both angles sum up to 90 degrees (also known as complementary angles)

15) Angles ADE and angle FDE are supplementary because they both add up to 180 degrees (supplementary angles)

16) Angles ADC and FDE are vertical because they are opposite of each other

17) Angles ADE and FDE are also linear pairs because both of them are adjacent (they both have a common side as well as a common vertex)

Hope this helps! ;)

Six times the sum of three consecutive odd integers is -18. What are the integers?
blondinia [14]

Answer:

1, -1, -3

Step-by-step explanation:

6(x+x+2+x+4)=-18

6(3x+6)=-18

18x+36=-18

18x=-54

x=-3

so x=-3, x+2=-1, and x+4=1

Help me!!!
nadya68 [22]

Step-by-step explanation:

You would start by using one of the equations to find y with x in the equation. You want to pick the easier one. I picked this one because it was evenly divisible.

5x+5y=50

5x=-5y+50

x=-y+10

Then you what to plug that in to the second equation and solve for y.

3(-y+10)+4y=32

-3y+30+4y=32

-3y+4y=2

y=2 (because you combined like terms)

Then you would plug back into the first equation and solve for x.

5x+5(2)=50

5x+10=50

5x=40

x=8

x=8, y=2

A quality control inspector has drawn a sample of 10 light bulbs from a recent production lot. Suppose 20% of the bulbs in the l
Neko [114]

Answer:

The probability is 0.0008.

Step-by-step explanation:

Let X represents the event of defective bulb,

Given, the probability of defective bulb, p = 20 % = 0.2,

So, the probability that bulb is not defective, q = 1 - p = 0.8,

The number of bulbs drawn, n = 10,

Since, binomial distribution formula,

P(x=r) = ^nC_r p^r q^{n-r}

Where, ^nC_r = \frac{n!}{r!(n-r)!}

Hence, the probability that exactly 7 bulbs from the sample are defective is,

P(X=7)=^{10}C_7 (0.2)^7 (0.8)^{10-7}

=120 (0.2)^7 (0.8)^3

=0.000786432

\approx 0.0008

First of all, x =-1 (y don’t change) so first 2 answer is out.
Now mirror to x-1 >>>
A(0,-1)
0 >> -1 is left one step so -1 left one step is -2
A(0,-1) >> A’(-2,-1)

A(-5,0)
-5 >> -1 is right 4 step so -1 right 4 step is 3
A’(3,0)
This is correct
Answer is D
