Answer:

slope = 1

Step-by-step explanation:

calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (10, 3 ) and (x₂, y₂ ) = (7, 0 )

m = $\frac{0-3}{7-10}$ = $\frac{-3}{-3}$ = 1

Martin kept track of the number of times he had to flip a coin before it landed tails up.

kobusy [5.1K]

Answer:

The dot plot of flip times increased gradually between 1, 2 and 3. The dot plot grew sharply from 3 to 4 and then 6.

Step-by-step explanation:

There are only 5 probabilities. It took Martin 1,2,3,4 and 6 flips to land a tail up. That 1,2,3 times of flips to land a tail up happened once. 4 times of flips to land a tail up happened 8 times. The greatest number of flips took to land tails up was 6 but the question didn't give details how many times it happens.

If r = 11 units and h = 8 units, then what is the volume of the cylinder shown above?

zhenek [66]

Answer:

968π ≈ 3041 . . . cubic units

Step-by-step explanation:

The usual formula for the volume of a cylinder is ...

V = πr²h

For your given dimensions, the volume is found by putting the values into the formula and doing the arithmetic.

V = π(11²)(8) = 968π . . . . cubic units

V ≈ 3041 cubic units

According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 20

Murljashka [212]

Answer:

There is not enough evidence to support the claim that Alaska had a lower proportion of identity theft than 23%.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 1432

p = 23% = 0.23

Alpha, α = 0.05

Number of theft complaints , x = 321

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.23\\H_A: p < 0.23$

This is a one-tailed test.

Formula:

$\hat{p} = \dfrac{x}{n} = \dfrac{321}{1432} =0.2241$

$z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Putting the values, we get,

$z = \displaystyle\frac{0.2241-0.23}{\sqrt{\frac{0.23(1-0.23)}{1432}}} = -0.5305$

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

P-value = 0.298

Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.

Conclusion:

Thus, there is not enough evidence to support the claim that Alaska had a lower proportion of identity theft than 23%.

Tyler picks 3/3 dozen apples. Olivia picks 5/6 dozen apples. Samantha picks 2/3 dozen apples. Who picks the least number of appl

Kitty [74]

For this case we have the following apple picking options, in dozens:

<em>Tyler:</em>

$\frac {3} {3} = 1$

Tyler picked up a dozen.

<em>Olivia:</em>

$\frac {5} {6} = 0.833$

Olivia collected 0.833 dozen apples.

<em>Samantha:</em>

$\frac {2} {3} = 0.667$

Samantha collected 0.667 dozens of apples.

Thus, it is observed that Samantha collected the least amount of apples.
