(t + 8) (-2) = 12

Distributive property >>>      -2t + -16 = 12

Inverse operation >>>>    -2t + -16+16 = 12+16
 
Simplify >>>>                 -2t = 28

Divide >>>>                       -2t/-2 = 28/-2

Final answer >>>>              t = -14

A die is rolled nine times and the number of times that two shows on the upper face is counted. If this experiment is repeated m
vivado [14]

Answer:

E(x) = 1.5\\

Step-by-step explanation:

Given

n = 9 -- number of rolls

Required

The mean of 2's

The distribution follows binomial distribution where:

X \to Binomial(n,p)

In this case:

p= \frac{1}{6} ---- the theoretical probability of rolling 2

So, the mean of 2's is calculated using:

E(x) = np

E(x) = 9 * \frac{1}{6}

E(x) = \frac{9}{6}

Simplify

E(x) = \frac{3}{2} or

E(x) = 1.5\\

How to solve this equation
solong [7]
The equations state -5(3s-9)=23. So 1st you wanna multiply 3s and -9 by -5. Which would get you -15s+45=23.
Than you subtract 23 from 45 which would equal -22 and than divide 15 from that
So the equation would equal 1.47
