Answer:
I'm not completly sure but im pretty sure its C.
Step-by-step explanation:
A. 1 Substitute y=−18y=−18 into y = x +12 y = x+ 12.− 18 = x +12 −18 = x+12
2 Solve for x x in −18 = x +12 − 18 = x + 12. x = −0 x = −30
3 Therefore, x = −30y = −18 x = −30 y = −18
B. The slope-intercept form is y = m x + b y = m x + b, where m m is the slope and
b b is the y-intercept. y = m x + b y = m x +
b Using the slope-intercept form, the slope is 0. m = 0
A. The slope-intercept form is y = m x + b y = m x + b, where m m is the slope and
b b is the y-intercept. y = m x + b y = m x +
b Using the slope-intercept form, the y intercept is 14. b = 14

Kim ran a mile in PE class. After resting for 1 hour her heart rate was 75 beats per minute. If her heart rate decreased by ⅖ , what was it immediately after she ran the mile?
Answer:
125
Step-by-step explanation:
since you take away 2/5 of the original number to get 75, 75 is equal to 3/5's of the original. You then divide 75 by 3, get 25, then multiply 25 by 5 to find the answer which is 125.

A number line going from 0 to 4. Numbers 0, 1, 2, 3, and 4 are marked on the line. Marks divide the spaces between each number into 2 equal parts. Ms. Cole has 4 yards of string. She cuts the string into pieces that are each 1 2 yard long. How many pieces of string does Ms. Cole have?
Answer:
8 pieces of string
Step-by-step explanation:
Given that :
Total yards of string = 4
Length in yd of each string = 1/2 yards
Number of pieces of string Ms. Cole has :
Total. Yards / length in yard of each string
4 / (1/2)
4 * (2 /1)
= 8/1
= 8 pieces of string.
what happens to the potential energy of the atoms during a phase change ?
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

Chari deposits $5,000 in a savings account earning 5.75% simple interest per year. Part B How much money will be in Chari's account after 10 years?
Answer:
$7,875

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)
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".
