Answer:
32,768 ways
Step-by-step explanation:
True/ false questions = 5 ; number of options = 2 (True or false)
Ways of answering = 2^5 = (2 * 2 * 2 * 2 * 2) = 32
Number of Multiple choice questions = 5
Number of options (A - D) = 4 options
Ways of answering = 4^5 = (4 * 4 * 4 * 4 * 4) = 1024
32 * 1024 = 32,768 ways

Which of the following equations is true for all values in Guthrie's input-output table?
AI +3 = y
B :+7=y
C 3x+1=y
D) 4.1 - 1=y
9514 1404 393
Answer:
C 3x +1 = y
Step-by-step explanation:
x-values increase by 1 from row to row.
y-values increase by 3 from row to row.
The slope of the linear function is the ratio of the y-increase to the x-increase:
m = ∆y/∆x = 3/1 = 3
The only offered choice with an x-coefficient of 3 is ...
C 3x +1 = y
__
If you check this against the table entries, you find it fits.
3(1) +1 = 4
3(2) +1 = 7
and so on.
N 1846 the depth of the river was 5 feet deep. In 1847 it dropped to 3.2 feet. This year, 1848, it rose to 6.6 feet. Find the percent change in river depth
Answer:
40.4%
Step-by-step explanation:
Given data
Initial depth= 5feet
Final depth= 5-3.2+6.6= 8.4feet
Hence the percent change
% change= FInal-initial/final*100
% change= 8.4-5/8.4*100
% change= 3.4/8.4*100
% change= 0.404*100
% change=40.4%
Hence the percent change is 40.4%
Percentage change between two measurement is the proportion of
change between the measurement expressed as a percentage.
The percentage change in the river depth in in 1848 is 106.25%
Reasons:
The given parameters are;
The depth of the river in the year 1846 = 5 feet
In the year 1847, the depth = 3.2 feet
In 1848 the depth = 6.6 feet
[tex]\displaystyle Percentage \ change = \mathbf{ \frac{Current \ depth - Previous \ depth}{Previous \ depth}}[/tex]
Which gives;
[tex]\displaystyle Percentage \ change = \frac{6.6 -3.2}{3.2} \times 100 = \mathbf{106.25 \%}[/tex]
The percentage change in the river depth in the current period = 106.25%

Suppose the ratio of girls to boys in your school is 19:17. There are 1908 students altogether. Write and solve a system of equations to find the total number of boys and girls in the school.
Answer:
901 boys and 1007 girls
Step-by-step explanation:
let b be the number of boys
let g be the number of girls
[tex]b + g = 1908\\17g = 19b\\g = \frac{19}{17} b\\b+\frac{19}{17} b = 1908\\2\frac{2}{17}b = 1908\\b = 901\\901 + g = 1908\\g = 1007[/tex]

Determine the slope of the line that passes through each pair of points. Write in simplest form. (3,8) and (1,5)
Answer:
y = 3/2x + 7/2
Step-by-step explanation:
First, you need to find the slope.
y2 - y1 / x2 - x1
= 5 - 8 / 1 - 3
= 3/2
The slope is 3/2x.
To find the y-intercept, plug any one of the coordinates into the equation, which is y = 3/2x + b
y = 3/2x + b
8 = 3/2(3) + b
8 = 9/2 + b
7/2 = b
The equation y = 3/2x + 7/2.
y=x+ 5
y = 6

A student claims that the expression “9 times the sum of a number and 13" is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?
Answer:
No, the student is not correct. The correct expression is 9(n+13).
Step-by-step explanation:
"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.
Answer:
Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.

The x - intercept of the graph of the expression is (5, 0).
We have the following expression -
- 4x = - 20
We have to find the x - intercept of the graph of this expression.
What is the Slope - intercept form of the equation of a straight line ?The Slope - intercept form of the equation of a straight line is as follows-
y = mx + c
where -
m - slope of line
c - intercept of line on y - axis.
According to the question -
- 4x = - 20
x = 5
Hence, the x - intercept of the graph of the expression is (5, 0). Refer the graph attached in the end.

Alex got a iPhone 11 for Christmas as a present. After spending 3 hours on the iPhone Alex decided to walk down the stairs to get a snack in the kitchen, but then he fell down the stairs because he was paying attention to the iPhone. He heard a crack, but luckily it wasn't his iPhone 11. It was his spinal cord.
Compare the price between the iPhone 11 and spinal cord repairence.
(This question was on a question in math and it's kinda funny XD)
Answer:
The difference between iPhone 11 and Spinal cord repairence is 99,300$.
Step-by-step explanation:
To be honest, this is a really weird question. But a spinal cord injury can cost up to 100,000$ a year. And an iPhone 11 cost around 700$. It really just depends on what repairence the person got, but if I am wrong then I hope you the best with your question lol. And since Alex didnt break his phone, you wouldnt count the repairs for the iPhone 11.
