Well let's break it down
$9.50 is what she makes an hour. Her goal is to earn $269.60
Step 1: First we need to write a variable. Our variable can be h since it is how many hours she need she to work
Step 2: Think! She works 9.50 and hour so our hour variable can go right aftear the nine! (Lots of people make the mistake of 9.50xh but sometimes the x can be confusing especially since x is the most common used mathematical variable, so always out it right next to it or use a dot in the middle)
Step 3: Piece it all together. So she makes 9.50h. And her goal is $269.60, so all we have to do now is $9.50h=$269.60. Since the equal sign makes this an accurate inequality.
NOW WE HAVE TO SOLVE IT
Since we are using multiplication in our inequality you can use the reverse operation of division to solve 9.50h= 269.60. Simply you just have to divide. 269.60/9.50.

Reagan has a savings account that earns 1.87% interest, compounded quarterly. If she needs $20,857 for a down payment on a house
MatroZZZ [7]
To solve this, we are going to use the compounded interest formula: A=P(1+ \frac{r}{n} )^{nt}
where 
A is the final amount after t years
P is the initial investment 
r is the interest rate in decimal form 
n is the number of times the interest is compounded per year
t is the time in years

We know from our problems that she needs $20,857 for a down payment on a house in 9 years, so A=20857 and t=9. To convert the interest rate to decimal form, we are going to divide the rate by 100%
r= \frac{1.87}{100} =0.0187
Since the interest is compounded quarterly, it is compounded 4 times per year; therefore, n=4. 
Lets replace the values in our formula to find P:
A=P(1+ \frac{r}{n} )^{nt}
20857=P(1+ \frac{0.0187}{4} )^{(4)(9)}
P= \frac{20857}{(1+ \frac{0.0187}{4} )^{(4)(9)}}
P= \frac{20857}{(1+ \frac{0.0187}{4} )^{36}}
P=17633.17

We can conclude that the correct answer is: <span>B. 17,633.17</span>

The choice between a z-test and a t-test for a population mean depends primarily on:
Tom [10]
Z-test should be used when the parent standard deviation is known and the sample size is greater than or equal to 30 (to satisfy the Central Limit Theorem). A T-test should be used when these two rules do not apply.

Write a function g whose graph represents the indicated transformation of the graph of f(x)=x+2; translation 2 units right
miss Akunina [59]

The  function g whose graph represents the indicated transformation of the graph of f(x)=x+2; translation 2 units right is g(x) = x

<h3>Translation of functions</h3>

Translation is a technique used to change the position of an image on an xy-plane. Given the function below;

f(x) = x +2

If the expression is translation 2 units to the right, the translation rule will be:

g(x) = f(x )- 2

Substitute

g(x) = x + 2 - 2

g(x) = x

Hence the  function g whose graph represents the indicated transformation of the graph of f(x)=x+2; translation 2 units right is g(x) = x
