You solve this through error and trial.

The is to get two matching numbers at both sides.

X 2x + 3 = 3 (x + 1) - x Answer

0 2(0) + 3 = 3 (0 + 1) - 0 3 = 3

1 2(1) + 3 = 3 (1 + 1) - 1 5 = 5

You do this all the way to ten. So far, we know x = 0 and x = 1 is correct

ELEN [110]

Answer:

P-value = 0.1515

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 2.2

Sample mean, $\bar{x}$ = 2

Sample size, n = 52

Alpha, α = 0.05

Population standard deviation, σ = 1.4

First, we design the null and the alternate hypothesis

$H_{0}: \mu =2.2\\H_A: \mu < 2.2$

We use one-tailed(left) z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{2 - 2.2}{\frac{1.4}{\sqrt{52}} } = -1.03$

Now, we calculate the p-value from the normal standard table.

P-value = 0.1515

Answer:

a) Should that 2x^2 + 3x - 20 = 0

Answer is YES

Step-by-step explanation:

30 = 1/2[4(x - 1) (2x+5)]

30 =2(x - 1) (2x+5)

30 = 2(2x^2 + 5x - 2x - 5)

30 = 2(2x^2 + 3x - 5)

15 = 2x^2 + 3x - 5

2x^2 + 3x - 20 = 0

a) Should that 2x^2 + 3x - 20 = 0

Answer is YES
