Answer:

x = -8

Step-by-step explanation:

x + (8/4) = -6

x × 4 + (8/4) × 4 = -6 × 4

4x + 8 = -24

4x = -24 - 8

4x = -32

x = -8

What is the distance rounded to the nearest tenth between the points(-5, 3) and (1, -1)?

kakasveta [241]

7.2 units is the distance between the two points (-5,3) and (1, -1).

The formula used for determining the distance between two points is shown below. In case this equation is used for finding the distance between the origin and a point, the value of x1 and y1 would just be equal to zero.

distance = $\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }$

The given points can be directly substituted for the formula.

Let: x2= 1, x1= -5, y2= -1, and y1= 3

distance = $\sqrt{[1-(-5)]^{2} + (-1 -3)^2 }$

distance = $\sqrt{(6)^2+(-4)^2}$

distance = $\sqrt{52}$ or 7.21 units

When rounded to the nearest tenth, the distance between the two points would be 7.2 units.

Suppose you are testing the null hypothesis that a population mean is less than or equal to 46, against the alternative hypothes

PolarNik [594]

Answer:

Option A) 2.5

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 46

Sample mean, $\bar{x}$ = 50

Sample size, n = 25

Alpha, α = 0.05

Population standard deviation, σ = 8

First, we design the null and the alternate hypothesis

$H_{0}: \mu \leq 46\\H_A: \mu > 46$

Formula:

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

Putting all the values, we have

$z_{stat} = \displaystyle\frac{50 - 46}{\frac{8}{\sqrt{25}} } =2.5$

Option A) 2.5
