How would I find the solution of -10= -5+x

Crazy boy [7]

Answer:

-5 = x

Step-by-step explanation:

First you begin with adding 5 to the other side of the equal sign.

Why? because you want to get "x" by itself, in other words, isolate the variable. and by adding 5 you make 0 on that side

So -10+5 = 5

What is -0.6(r+0.2) = 1.8 ???

lana66690 [7]

Answer:

r = -3.2

-0.6(r+0.2) = 1.8

Divide by -.6

r+.2 = -3

Subtract .2 from each side

r+.2-.2 = -3-.2

r = -3.2

in a certain normal distribution, 6.3% of the area lies to the left of 36 and 6.3% of the area lies to the right of 42. Find the

KATRIN_1 [288]

As the normal distribution is symmetric the mean is (36 + 42) / 2 = 39

p(X < 42) = 1 - 0.063 = 0.937

From tables Φ (1.53) = 0.9370

From this time:

42 is 1.53 standard deviations above the mean

42 = 39 + 1.53s

1.53s = 3

Standard deviation is = 1.96
