20 POINTS! The following graph shows the amount of money Jonah earns when he babysits for the family who lives next door. Based on the graph, which of the following statements are true? Select ALL that apply.
When Jonah babysits one hour, he earns $7.50.
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
The number of hours Jonah works depends on how much he earns.
Answer:
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
Step-by-step explanation:
When Jonah babysits one hour, he earns $7.50.
looking at the graph we see at 1 hour he earns 4 dollars false
The equation e = 4 h can be used to describe this situation.
The slope is 4 so y = 4x e = 4h would also work true
Jonah earns $20 to babysit for 5 hours.
Using our equation from above
e = 4*5 = 20 true
The number of hours Jonah works depends on how much he earns.
This would be false
The dependent variable is on the y axis. The amount he earns depends on how much he works

Which of the following could be the equation of the function below?
On a coordinate plane, a curve crosses the y-axis at y = negative 1.5. It has a maximum at negative 1.5 and a minimum at negative 2.5. It goes through 2 cycles at pi.
y = 0.5 cosine (2 (x minus StartFraction pi Over 2 EndFraction)) + 2
y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2
y = 0.5 cosine (4 (x + pi)) + 2
y = 0.5 cosine (2 (x minus pi)) minus 2
Answer:
y = 0.5 cosine (4 (x - pi/2)) - 2
Step-by-step explanation:
Taking the general form:
y = A cosine (Bx - Cπ)) + D
In the following case. the constants are:
y = 0.5 cosine (4x - 2π)) - 2
A: 0.5
B: 4
C: 2π
D: -2
The range of this function is:
range = [-|A|+D, |A|+D]
range = [-0.5-2, 0.5-2]
range = [-2.5, -1.5]
Which coincides with "It has a maximum at negative 1.5 and a minimum at negative 2.5"
At x = 0, the function value is:
y = 0.5 cosine (4(0) - 2π)) - 2
y = 0.5 - 2 = -1.5
As indicated in "a curve crosses the y-axis at y = negative 1.5"
The period of the function is:
period: 2π/B
period = 2π/4 = π/2 or 2 cycles at π
as described in "It goes through 2 cycles at pi."
Answer:
B) y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2

Results of a blood test are normally distributed with a mean of 6.2 and a standard deviation of 1.5. What is the probability that a patient has a blood test result less than or equal to 8.3?
Answer:
91.92%
Step-by-step explanation:
Given that:
Mean (μ) = 6.2, standard deviation (σ) = 1.5
Z score is a measure in statistics to determine the relationship of a measured value with the mean. It is given by the equation:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
To calculate the probability that a patient has a blood test result less than or equal to 8.3, we need to calculate the z score of 8.3
For x = 8.3, the z score is:
[tex]z=\frac{x-\mu}{\sigma}=\frac{8.3-6.2}{1.5} =1.4[/tex]
From the probability distribution table:
P( x ≤ 8.3) = P(z < 1.4) = 0.9192 = 91.92%
What is the value of x?

The area of a triangle is related to the base and height of the triangle by the formula a = bh/2. Rewrite this equation with b solved in terms of a and h.
Answer: b = 2a/h
Step-by-step explanation:
a = bh/2
multiply each side by 2
2a = bh
divide each side by h
2a/h = b
Answer:
b = 2a/h
The area of a triangle is related to the base and height of the triangle by the formula a = bh/2

Answer:
0.03
Step-by-step explanation:
6 is greater then 5, so you add 1 to 2 making 0.03
Answer:
0.03
Step-by-step explanation:
the digit after the first 2 is a 6 and you always round up so it would be 0.03.
Solve for m. –5 − 5m = –6m
m= _
Answer:
M = 5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5−5m=−6m
−5+−5m=−6m
−5m−5=−6m
Step 2: Add 6m to both sides.
−5m−5+6m=−6m+6m
m−5=0
Step 3: Add 5 to both sides.
m−5+5=0+5
m=5

What is the next term of the geometric sequence?
7, 21, 63
First find the common ratio of this geometric sequence.
We will use [tex]r = \frac{a2 }{a1 }[/tex].
The second term is 21 and the first term is 7.
So we have [tex]\frac{21}{7}[/tex] and this reduces to [tex]\frac{3}{1}[/tex] or 3.
So, we take the last term in our geometric sequence
and multiply it by the common ratio we just found.
So we have 63 · 3 which is 189.
So the next term in this geometric sequence is 189.
A coin has heads on one side and tails on the other the coin is tossed 12 times and lands heads up four times which best describes what happens when the number of trials increases significantly
Answer:
The number of occurrences for both possible events(heads or tails) will be closer to the expected outcome. By that I mean that of all the total outcomes heads will be about half of them and so will tails.

The number of people using an older version of a spreadsheet program decreases at a rate that is proportional at any time to the number of people still using the version at that time.
There were 10{,}00010,00010, comma, 000 people using the older version of the spreadsheet program when the new version first came out. The number of people still using the older version decreases by 20\%20%20, percent every 666 months.
Answer:
The decrease in the use of older version is given by,[tex]y = 10000 \cdot0.60^{t}[/tex].
Step-by-step explanation:
It is provided that the number of people using an older version of a spreadsheet program decreases at a rate that is proportional at any time to the number of people still using the version at that time.
The exponential decay function is given as follows:
[tex]y=a(1-r)^{t}[/tex]
Here,
y = final value
a = initial value
r = decay rate
t = time taken
It is provided that there were 10,000 people using the older version of the spreadsheet program when the new version first came out. And the number of people still using the older version decreases by 20% every 6 months.
So, every half-yearly the decrease in the number of people using the older version is 20%. This implies for a year the decay rate is 40%.
Then the decrease in the use of older version is given as follows:
[tex]y=10000(1-0.40)^{t}\\\\y=10000\cdot 0.60^{t}[/tex]

Write the equation of the line in slope intercept form y=mx + b that would have the slope of two and crosses through the ordered pair (-3,5).
Answer:
y=2x+11
Step-by-step explanation:
Slope is 2
y=2x+b
plug in (-3,5)
5=-6+b
b=11
y=2x+11
Answer:
y = 2x+11
Step-by-step explanation:
y = mx+b where m is the slope and b is the y intercept
We know the slope is 2
y =2x+b
We have a point (-3,5)
Substitute this into the equation
5 = 2(-3)+b
5 = -6+b
Add 6 to each side
5+6 = b
11 =b
The equation is
y = 2x+11
