4x+11+7x-6+43= 180
11x = 132
x = 12
7(12)-6 = 78

Answer:

∠RTS = 57°

x=9

Explanation:

By just factoring out integers starting from 10 and going down. You can factor each one out. Add all together. And see whether all angles equal 180. And if they do. Then that's what x equals. Not the smartest of explanations but it works lol.

Assume the readings on thermometers are normally distributed with a mean of 0degreesc and a standard deviation of 1.00degreesc.
Tanzania [10]

Let Z be the reading on thermometer. Z follows Standard Normal distribution with mean μ =0 and standard deviation σ=1

The probability that randomly selected thermometer reads greater than 2.07 is

P(z > 2.07) = 1 -P(z < 2.07)

Using z score table to find probability below z=2.07

P(Z < 2.07) = 0.9808

P(z > 2.07) = 1- 0.9808

P(z > 2.07) = 0.0192

The probability that a randomly selected thermometer reads greater than 2.07 is 0.0192

Expression when m=8 and n=7 n+6m
Andrews [41]
All you have to do is plug m and n into the equation:

n+6m

Since n=7, you'll get:

7+6m

And since m=8, you'll get:

7+6(8)

And by doing the order of operations (PEMDAS), you'll start off multiplying 6 and 8, which is 48, then add 7, which is 55.

Your answer should be 55!
