Answer:
5) I=1848. total=3248
Step-by-step explanation:
interest = principal x rate x time /100
I=prt/100
p=1400
r=16.5%
t=8
i=1400*16.5*8/100
i=14*16.5*8
I=112*16.5
I=1848

Which statement describes the domain of the function
Answer:
D: All real numbers except x=-1 and x=1
Step-by-step explanation:
Step-by-step explanation:
The domain of the rational expression is when the denominator is defined. (non-zero)
When the denominator is 0,
4x² - 4 = 0.
=> x² - 1 = 0, (x + 1)(x - 1) = 0, x = -1 or x = 1.
Hence the answer is all real numbers except x = -1 and x = 1.

Question 13 pts
Data from Ivy Tech's advising center shows the wait times as a normal distribution with the average as 20 min and a standard deviation as 5 min.
Using the empirical rule, what percent of students wait between 15 and 25 minutes?
What percent wait more than 20 min?
Using the empirical rule, what is the chance that someone waits less than 5 min?
Answer:
1. 68%
2. 50%
3. 15/100
Step-by-step explanation:
Here, we want to use the empirical rule
1. % waiting between 15 and 25 minutes
From what we have in the question;
15 is 1 SD below the mean
25 is 1 SD above the mean
So practically, we want to calculate the percentage between;
1 SD below and above the mean
According to the empirical rule;
1 SD above the mean we have 34%
1 SD below, we have 34%
So between 1 SD below and above, we have
34 + 34 = 68%
2. Percentage above the mean
Mathematically, the percentage above the mean according to the empirical rule for the normal distribution is 50%
3. Probability that someone waits less than 5 minutes
Less than 5 minutes is 3 SD below the mean
That is 0.15% according to the empirical rule and the probability is 15/100

There are 20 houses on Rainbow Street. 45% of the houses have holiday decorations in their yard. How many houses have decorations?
Answer:
9 houses
Step-by-step explanation:
45% of 20 is 9 so the answer is 9
Total 9 houses have decoration on Rainbow Street.
What is percentage?Percentage is a part of the whole number. It is denoted by % sign.
1 %= 1/100.
Given that,
Total number of houses on Rainbow Street = 20,
The percentage of the houses which have decorations = 45%
The number of houses which have decoration
= 20×(45/100)
= 9
There are 9 houses that have decorations.

Remember to follow the order of operation, PEMDAS. PEMDAS stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division

5. 9(7x - 4) = 27
First, distribute 9 to all terms within the parenthesis:
9(7x - 4) = 27
(9 * 7x) - (9 * 4) = 27
63x - 36 = 27
Next, isolate the variable, x. Do the opposite of PEMDAS.
First, add 36 to both sides:
63x - 36 (+36) = 27 (+36)
63x = 27 + 36
63x = 63
Isolate the variable, x. Divide 63 from both sides:
(63x)/63 = (63)/63
x = 63/63 = 1
x = 1
~
6. 5(3x + 8) = 175
First, distribute 5 to all terms within the parenthesis:
5(3x + 8) = (5 * 3x) + (5 * 8) = 15x + 40
15x + 40 = 175
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 40 from both sides:
15x + 40 (-40) = 175 (-40)
15x = 175 - 40
15x = 135
Next, divide 15 from both sides of the equation:
(15x)/15 = (135)/15
x = 135/15 = 9
x = 9

7x - 14=35 what value of x makes this equation true
Hello there, and welcome to Brainly!
In the following equation, you are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 14 to both sides of the equation:
7x - 14 (+14) = 35 (+14)
7x = 35 + 14
7x = 49
Next, divide 7 from both sides:
(7x)/7 = (49)/7
x = 49/7
x = 7
7 is the value for x that will make the equation true.
