Solve the inequality <br> 3(x – 2) + 1 ≥ x + 2(x + 2)

leva [86]

Answer:

No solution.

Step-by-step explanation:

Step 1: Write inequality

3(x - 2) + 1 ≥ x + 2(x + 2)

Step 2: Solve for <em>x</em>

Distribute: 3x - 6 + 1 ≥ x + 2x + 4
Combine like terms: 3x - 5 ≥ 3x + 4
Add 5 to both sides: 3x ≥ 3x + 9
Subtract 3x on both sides: 0 ≥ 9

Here we see that the statement is false. Therefore, you cannot solve for the inequality.

(a) Find z such that the proportion of observations that are less than z in a standard normal distribution is 0.36. (Enter your

Alisiya [41]

Answer:

a) z = -0.358

b) z = 0.358

Step-by-step explanation:

We are given a standard normal distribution.

a) We have to find the value of z such that the proportion of observations that are less than z in a standard normal distribution is 0.36.

That is,

$P(Z$

This value will be calculated with the help of a standard normal table.

From standard normal table we have,

$P(z\leq -0.358) = 0.36$

Thus, for z equal to -0.358 the proportion of observations that are less than z in a standard normal distribution is 0.36

b) We have to find the value of z such that 36% of all observations from a standard normal distribution are greater than z.

$P(Z>z) = 0.36$

This value will be calculated with the help of a standard normal table.

$= 1 -P( Z > z)=1 - 0.36 = 0.64$

$P( z \leq z)=0.64$

Calculation the value from standard normal z table, we have,

$P(z \leq 0.358) = 0.64$

Thus, 36% of all observations from a standard normal distribution are greater than z equal to 0.358
