Find the measure of x. X = -1 X = 9 X = 13

Mathematics
1 answer:
Ivan2 years ago
3 0

Answer:

x = 7

Step-by-step explanation:

Given that ∠PRQ = 135°

therefore ∠ QRS = 180 - 135 = 45° (both the 2 adjacent angles sit on the straight line)

Since ∠ QRS = 45°

therefore ∠RST = 45° ( They are alternate angles)

Since ∠RST = 45°

therefore ∠UST = 180 - 45 = 135°  (both the 2 adjacent angles sit on the straight line)

∠UST =  135°  

∠UST = 15(x + 2)

therefore,

15(x + 2) = 135

x + 2 = 9

x = 7

Multiple Choice, could somebody help me with this?
ololo11 [35]

Answer:

option 5 and option 6

Step-by-step explanation:

option 5.

dilate with a scale factor of 1/2.

This is because we have to take as a reference the base circumference of the point p as the problem says, so we see the radius of that circumference is twice that of the other, so to get there it must be multiplied by 1/2

option 6.

reflect in the y-axis.

we can see that the distance of the 2 points to the y axis is the same, which means that it is reflected on the y axis

48% of US adults have very little confidence in newspapers you randomly selected 10 US adults. Find the probability that the num
aivan3 [116]

Answer:

P(x = 5) = 0.2441

Step-by-step explanation:

Given

p = 0.48 --- proportion that have very little confidence

n = 10 --- sample

Required

Determine the probability that exactly 5 have very little confidence

This question will be solved using binomial probability:

P(x) = ^nC_xp^x(1-p)^{n-x}

In this case: x = 5.

So, we have:

P(x = 5) = ^{10}C_5*0.48^5(1-0.48)^{10-5}

P(x = 5) = ^{10}C_5*0.48^5*0.52^5

P(x = 5) = 252*0.48^5*0.52^5

P(x = 5) = 0.2441

The population of a small town was 10,800 in 2003. Since then, the population has
nordsb [41]

Answer: 5940

Step-by-step explanation: I don't know if it's for sure right but here

First I knew 10,800 was 100% and I wanted to find 2.5%

So I did:

10,800 divided by 100 and I got 108 = 1%

Than you want to do

108 x 2.5 = 270 ( 2.5% )

After that you wanted to find out how much years apart so

2021 - 2003 = 18

Then

18 x 270 = 4,860

Last of all you have to do

10,800 - 4,860 = 5940
