The answer is 6. You can find slope by using the slope formula: M= y1 - y2 / x1 - x2. In this case you can choose any two points from the table. I chose the second two points. the equation would then be (7-1) / (2-1). It would then be 6/1 or 6.
Hope this helped(:

Find the missing variable for a parallelogram:

irakobra [83]

Since the formula to find the area of a parallelogram is base times height (A=bh), and you have been given the area and base already, you can set up an equation. Let h=height in this formula. h x 3.4 = 25. Using this formula, to find the height, you would divide 25 by 3.4 and get approximately 7.35 inches. So, your height= 7.35in. Hope this helps!

A trucking firm suspects that the mean life of a certain tire. it uses is less than 33,000 miles. To check the claim, the firm r

Mice21 [21]

Answer:

We accept the alternate hypothesis. We conclude that the mean lifetime of tires is is less than 33,000 miles.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 33,000 miles

Sample mean, $\bar{x}$ = 32, 450 miles

Sample size, n = 18

Alpha, α = 0.05

Sample standard deviation, s = 1200 miles

a) First, we design the null and the alternate hypothesis

$H_{0}: \mu = 33000\text{ miles}\\H_A: \mu < 33000\text{ miles}$

b) Level of significance:

$\alpha = 0.05$

c) We use One-tailed t test to perform this hypothesis.

d) Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$ Putting all the values, we have

$t_{stat} = \displaystyle\frac{32450 - 33000}{\frac{1200}{\sqrt{18}} } = -1.9445$

Now, $t_{critical} \text{ at 0.05 level of significance, 17 degree of freedom } = -1.7396$

Rejection area:

$t < -1.7396$

Since,

$t_{stat} < t_{critical}$

e) We fail to accept the null hypothesis and reject it as the calculated value of t lies in the rejection area.

f) We accept the alternate hypothesis. We conclude that the mean lifetime of tires is is less than 33,000 miles.

$\Large\maltese\underline{\textsf{A. \space What is Asked}}$

Find the gradient of the line segment between the points $\bf{(4,3)\:and\:(5,6)}$

$\Large\maltese\underline{\textsf{B. This problem has been solved!}}$

The formula used, here is

$\bf{m=\dfrac{y2-y1}{x2-x1}$

$\cline{1-2}$

Now let's put in the co-ordinates from these two points.

$\bf{m=\dfrac{6-3}{5-4}}$ | subtract on top & bottom

$\bf{m=\dfrac{3}{1}}$ | divide

$\bf{m=3}$

$\cline{1-2}$

$\bf{Result:}$

$\bf{=m=3}$

$\boxed{\bf{ aesthetic\not101}}$
