Answer:
$1,823.20
Step-by-step explanation:
You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.
<em>I = interest amount
</em>
<em>P = principal amount
</em>
<em>r = interest rate (decimal form)
</em>
<em>t = time
</em>
<em />
First, change 4% into its decimal form:
4% -> -> 0.04
Next, plug in the values:
Rita will be charged $1,823.20 worth of interest at the end of one year.

Answer:
Yes, it would be statistically significant
Step-by-step explanation:
The information given are;
The percentage of jawbreakers it produces that weigh more than 0.4 ounces = 60%
Number of jawbreakers in the sample, n = 800
The mean proportion of jawbreakers that weigh more than 0.4 = 60% = 0.6 = =p
The formula for the standard deviation of a proportion is
Solving for the standard deviation gives;
Given that the mean proportion is 0.6, the expected value of jawbreakers that weigh more than 0.4 in the sample of 800 = 800*0.6 = 480
For statistical significance the difference from the mean = 2× = 2*0.0173 = 0.0346 the equivalent number of Jaw breakers = 800*0.0346 = 27.7
The z-score of 494 jawbreakers is given as follows;
Therefore, the z-score more than 2 × which is significant.
Answer:
x^2 - 15x - 27
---------------------- (Answer C)
9
Step-by-step explanation:
(h - g)(x) is the difference between funcions h and g. Subtract g(x) from h(x) as follows:
x^2 + 2 - x
-(4x + 5)
-------------------
x^2 - 5x - 3 = (h - g)(x)
To find (h - g)(x/3), substitute x/3 for x in x^2 - 5x - 3 = (h - g)(x), obtaining:
(x/3)^2 - 5(x/3) - 3
We must expand this and then combine like terms:
x^2/9 - (5/3)x - 3
The LCD of these three terms is 9. The first term stays as is. The second term becomes (15/9)x. The third term becomes 27/9.
Combining these three terms, all with denominator 9, we get:
x^2 - 15x - 27
----------------------
9
This matches Answer C.
