What is the value of y in the equation, 5x+2y=20, when x=0.3

gregori [183]

Answer:

y = -5/2x + 10

Step-by-step explanation:

Step one: Add -5x to both sides.

5x + 2y + -5x = 20 + -5x

2y = -5x + 20

Step two: Divide both sides by two.

2y/2 = -5x + 20/ 2

y = -5/2x + 10

Hope my answer help.

Candice buys 2/8 of a container of roasted peanuts. Alan buys 2/3 of a container. Both containers are the same size. Candice say

xz_007 [3.2K]

Since my name is in this question, I'll answer it :)

Answer:

Yes, she's right.

Step-by-step explanation:

2/8 is simplified to 1/4. Between 1 and 1/2, it is 1/4. So yes, I (Candice) was right. :)

Consider the following hypothesis test: H 0: 20 H a: < 20 A sample of 60 provided a sample mean of 19.5. The population stand

viva [34]

Answer:

We reject the null hypothesis and accept the alternate hypothesis. Thus, it be concluded that the population mean is less than 20.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 60

Sample mean, $\bar{x}$ = 19.5

Sample size, n = 60

Alpha, α = 0.05

Population standard deviation, σ = 1.8

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 20\\H_A: \mu < 20$

We use One-tailed z test to perform this hypothesis.

Formula:

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

Putting all the values, we have

$z_{stat} = \displaystyle\frac{19.5 - 20}{\frac{1.8}{\sqrt{60}} } = -2.151$

Now, $z_{critical} \text{ at 0.05 level of significance } = -1.64$

Since,

$z_{stat} < z_{critical}$

We reject the null hypothesis and accept the alternate hypothesis. Thus, it be concluded that the population mean is less than 20.

Write an equation of a line in slope-intercept form with the given slope and y- intercept

Aleks04 [339]

Answer:

y=1/4x+3

Step-by-step explanation:

Slope intercept form is written as (y=mx+b)

<u>To define those variables:</u>

- m is the slope

- b is the y-intercept

We have been given both the slope, and the y intercept, therefore just plug in the numbers into the form:

y=1/4x+3
