Step-by-step explanation:

Rearrange this algebraically to solve for

Price per pound

. To do this, divide both sides of the equation by

Number of pounds

to get

Price per pound

by itself.

Total cost = number of pound

=Total of cost /Number of pounds

=33/5

=$6.6

Answer:

10y²/3x³

Step-by-step explanation:

You want to multiply the numerator times the numerator, and the denominator times the denominator.

This makes it 20y⁴x²/6x⁵y²

You can then simplify it further to 10y⁴x²/3x⁵y²

You can than subtract the power for futher simplification so the final answer is

10y²/3x³

In a study of 799 randomly selected medical malpractice lawsuits, it was found that 499 of them were dropped or dismissed. Use

Mademuasel [1]

Answer:

Claim is true that most medical malpractice lawsuits are dropped or dismissed.

Step-by-step explanation:

Given :In a study of 799 randomly selected medical malpractice lawsuits, it was found that 499 of them were dropped or dismissed.

To Find : Use a 0.05 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed.

Solution:

n = 799

x = 499

We will use one sample proportion test

$\widehat{p}=\frac{x}{n}\\\widehat{p}=\frac{499 }{ 799}\\\widehat{p}=0.6245$

We are given that the claim is most medical malpractice lawsuits are dropped or dismissed.

Probability of dropped or dismissed is 1/2

$H_0:p=0.5\\H_a:p>0.5$

Formula of test statistic = $\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

= $\frac{0.6245-0.5}{\sqrt{\frac{0.5(1-0.5)}{799}}}$

= 7.038

p value (z>7.038) is 0

α =0.05

So, p value < α

So, we reject the null hypothesis

So,claim is true

Hence most medical malpractice lawsuits are dropped or dismissed.

Write an equation parallel to y=3x−1 and goes through the point (-2, -13)

solong [7]

Answer:

y=3x-7

Step-by-step explanation:

we use the equation of the line:

y=mx+b

if the line is parallel, then the slope(m) of the line stays the same:

y=3x+b

we then substitute the ordered pair into the equation and solve for b:

-13 = 3(-2)+b

-13 = -6+b

-13+6 = b

-7 = b

now we substitute the b value into the original equation and the answer:

y=3x-7

Hope this helps :)
