y= 3/2 x - 2
Step-by-step explanation:
so you have to find the slope which would be
m =
y2 - y1
x2 - x1
then you find you points that you are using (2, 1) and (0, -2)
when you plug it in it is
m=
-2-1
0-2
you simplify the numbers and get rid of the negatives to get m=3/2 x
then your y intercept is where your line meets the y axis or wherever x=0
so your y intercept is (0, -2) so the b = -2

About 5% of hourly paid workers in a regioner the prevailing minimum wage or less A grocery chain offers discount rates to companies that have at least 30 employees who earn the prevailing minimum wage or less Complete parts
through (c) below
(a) Company Ahas 281 employees What is the probability that Company A will get the discount?
(Round to four decimal places as needed)
Answers
Answer:
0
Step-by-step explanation:
Let X to be a random variable that looks a binomial distribution which denoted the number of employees out of the 281 who earn the prevailing minimum wage or less
The sample size n = 281
The population parameter p = 5% = 0.05
Using normal approximation for the mean.
[tex]\mu = np[/tex]
[tex]\mu = 281\times 0.05[/tex]
[tex]\mu = 14.05[/tex]
The standard deviation is:
[tex]\sigma = \sqrt{np(1-p)}[/tex]
[tex]\sigma = \sqrt{281 \times 0.05(1-0.05)}[/tex]
[tex]\sigma = \sqrt{281 \times 0.05(0.95)}[/tex]
[tex]\sigma = \sqrt{13.3475}[/tex]
[tex]\sigma =3.6534[/tex]
By using continuity correction; the sample mean x is:
x = 30 - 0.5
x = 29.5
The z statistic test can now be as follows:
[tex]Z = \dfrac{x-\mu}{\sigma}[/tex]
[tex]Z = \dfrac{29.5-14.05}{3.6534}[/tex]
[tex]Z = \dfrac{15.45}{3.6534}[/tex]
Z = 4.23
Thus, the probability that company A will get a discount is
P(X ≥ 30) = P(Z >4.23)
= 1 - P(Z < 4.23)
By using the Excel function for the z score 4.23 i.e. "=1 - NORMSDIST(4.23)" we get;
= 0.0000
Let X be a random variable that shows how many employees out of 281 earn the prevailing minimum wage or less.
X does have a binomial distribution with parameters [tex]n = 281 \ \ and\ \ p = 0.05[/tex]:
Since [tex]np \ \ and\ \ n(1-p)[/tex] are greater than 5, X does have a normal distribution of parameters when using the normal approximation.
[tex]\to \mu= np=281 \times 0.05= 14.05[/tex]
Calculating the standard deviation:
[tex]\to \sigma=\sqrt{np(1-p)}\\\\[/tex]
[tex]= \sqrt{281 \times 0.05 (1-0.05)}\\\\=\sqrt{281 \times 0.05 \times 0.95}\\\\ =\sqrt{14.05 \times 0.95}\\\\ =\sqrt{13.3475}\\\\=3.653[/tex]
Continuity correction is required in this case. The z-score for [tex]X = 30-0.5 = 29.5[/tex]:
[tex]\to z= \frac{X- \mu}{\sigma}[/tex]
[tex]=\frac{29.5-14.05}{3.653}\\\\=\frac{15.45}{3.653}\\\\=4.2294\\\\[/tex]
The likelihood that Company Its will receive the discount:
[tex]\to P(X\geq 30)=P(z>4.229)=0.0000117\approx \ 0.0000[/tex]
Therefore, the final answer is "0".

what happens to the potential energy of the atoms during a phase change ?
Answers
Answer:
The energy that is changing during a phase change is potential energy. During a phase change, the heat added (PE increases) or released (PE decreases) will allow the molecules to move apart or come together. Heat absorbed causes the molecules to move farther apart by overcoming the intermolecular forces of attraction.
Answer: I believe it turns into kinetic energy
Step-by-step explanation:
Kinect energy is the opposite of potential energy
