Answer:

y = -x - 2

Step-by-step explanation:

You can start with the equation of a line in the slope-intercept form.

y = mx + b

m = slope

b = y-intercept

Look at the graph to find the y-intercept. At what point on the y-axis does the graph intersect the y-axis? Answer: -2. The y-intercept is -2. The value of b is -2.

Now we hjave

y = mx + (2)

or simply

y = mx - 2

Now we need to find the slope.

The slope is the ratio of the rise (difference in y) over the run (difference in x).

Look at the point (6, -7) that is shown in your graph. Go up 1 unit vertically. That is a rise of 1. Now go left 1 unit horizontally. That is a run of -1.

slope = m = rise/run = 1/(-1) = 1

The slope is 1. Now we replace m with -1.

y = mx - 2

y = -1x - 2

y = x - 2

Answer: y = -x - 2

Answer: The equation of this graph can be written in slope intercept form which is what I am assuming you want. If you do not want that form you can convert to any other form that you so desire. The slope intercept equation for this graph would be y = -1x - 2. The -1 is the slope of the line and the -2 is the y intercept.

Suppose that in a random selection of 100 colored candies, 24% of them are blue. The candy company claims that the percentage

LuckyWell [14K]

Answer:

We conclude that the percentage of blue candies is equal to 23% at 0.01 significance level.

Step-by-step explanation:

We are given that in a random selection of 100 colored candies, 24% of them are blue.

The candy company claims that the percentage of blue candies is equal to 23%.

Let p = percentage of blue candies.

So, Null Hypothesis, $H_0$ : p = 23% {means that the percentage of blue candies is equal to 23%}

Alternate Hypothesis, $H_A$ : p $\neq$ 23% {means that the percentage of blue candies is different from 23%}

The test statistics that would be used here One-sample z proportion test statistics;

T.S. = $\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n}} }$ ~ N(0,1)

where, $\hat p$ = sample proportion of blue colored candies = 24%

n = sample of colored candies = 100

So, test statistics = $\frac{0.24-0.23}{\sqrt{\frac{0.24(1-0.24)}{100}} }$

= 0.234

The value of z test statistics is 0.234.

Now, at 0.01 significance level the z table gives critical values of -2.5758 and 2.5758 for two-tailed test.

Since our test statistics lies within the range of critical values of z, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which we fail to reject our null hypothesis.

Therefore, we conclude that the percentage of blue candies is equal to 23%.

Solve equation. Show steps 8+x=4x+2

statuscvo [17]

Answer:

x=2

Step-by-step explanation:

8 + x = 4x +2

Subtract 4x from both sides:

8 + x - 4x = 4x + 2 - 4x

Group like terms:

x - 4x + 8 = 4x + 2 -4x

Simplify the arithmetic:

-3x + 8 = 4x + 2 -4x

Group like terms:

-3 + 8 = 4x - 4x + 2

Simplify the arithmetic:

-3x + 8 = 2

Elodia [21]

We have been given that a sphere and a cylinder have the same radius and height. The volume of the cylinder is 21 meters cubed. We are asked to find the volume of the sphere.

We know that height of sphere is equal to its radius. This means that $r=h$ .
