Answer:

7 pigs, 16 chickens

Step-by-step explanation:

p= pigs, c= chickens, legs= 60, number of pigs & chickens= 23

System of Equations:

Equation 1: $p+c=23$ would be $23-p=c$
Equation 2: $4p+2c=60$ for the legs

Then, use substitution & solve:

$4p+2(23-p)=54\\4p+46-2p=54\\4p-2p=8\\2p=8\\p=7$

Now, plug $p=7$ back into $23-p=c$ to get c

$23-p=c\\23-7=c\\c=16$

Answer: 7 pigs, 16 chickens or $p=7$ and $c=16$

To check your work, plug those solutions back into the system.

Answer:

a) y = 6x - 3

b) 1/3y = 2x -1

The first thing you need to do is isolate (y) in the second equation

3 x (1/3y) = 3 x (2x - 1)

y =6x - 3

After isolating (y) in equation b they end up being the same.

Graphing:

In order to graph this, you have to make the first point at (0, -3) since this is the Y-intercept of the equation.

In order to graph the other points, you must move 6 units up and 1 unit to the right. Or vise versa If you need a visual I'll gladly link one.

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.

The graph f(x)=x^2 was transformed to create the graph g(x)=−(3x)^2.

pishuonlain [190]

Answer:

the first one.

Step-by-step explanation:

the "-" sign simply turns everything upside-down. what was originally above the x-axis is now below it, and what was below the x-axis is now above it. hence : a reflection over the x-axis.

and 3x compared to x simply makes us race "faster" along the x-axis. we get now at x the functional value we would have gotten at 3x with the original function. so, the function graph appears compressed in the left-right (horizontal) direction compared to the original graph.

Simplify completely 18 s t to the fourth power over 52 s cubed t times 16 s cubed over 9 s squared t???

rjkz [21]

If I understand clearly, the expression is
(18st^4/52s^3t)(16s^3/9s^2t)

To simply the expression, we simply have to multiply the constants and reduce the product to the lowest terms and apply the laws on exponents to simplify the variables. So, the answer would be:
8t^2/13s
