The value of a collectible coin can be represented by the equation y = 2 x + 15, where x represents its age in years and y repre

Masteriza [31]

Answer:

53$

Step-by-step explanation:

They tell you the equation of how much the coin is worth after x amount of years

Step 1: Substitute x=19 into the equation y=2x+15

y = 2(19) + 15

Step 2: Solve for y

y = 2(19) + 15

y = 38 + 15

y = 53

Therefore the coin is worth 53 dollars after 19 years

When testing a claim that the majority of adult Americans are against the death penalty for a person convicted of murder, a rand

Black_prince [1.1K]

Using the z-distribution, it is found that the p-value is of 1.

At the null hypothesis, it is tested that the majority is not against the death penalty, that is:

$H_0: p \neq 0.5$

At the alternative hypothesis, it is tested that the majority is against the death penalty, that is:

$H_1: p > 0.5$

The test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

In which:

$\overline{p}$ is the sample proportion.

p is the proportion tested at the null hypothesis.

n is the sample size.

In this problem, the parameters are: $\overline{p} = 0.27, p = 0.5, n = 491$ .

Then, the value of the test statistic is:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

$z = \frac{0.27 - 0.5}{\sqrt{\frac{0.5(0.5)}{491}}}$

$z = -10.19$

Using a z-distribution calculator, for a right-tailed test, as we are testing if the proportion is greater than a value, the p-value is of 1.

8 = 4 - 2x - 2x +5 = 17 12= - 3 ( x+ 5)

max2010maxim [7]

$8 = 4 - 2x\\8 + 2x = 4\\2x = -4\\x = -2$

$- 2x +5 = 17\\-2x =12\\x = -6$

$12= - 3 ( x+ 5)\\12 = -3x -15\\-3x =27\\x= -9$
