Some descriptive statistics for a Set of test scores are shown above for this test a certain student has a standardized score of z=-1.2 what score did the student receive on the test
Complete Question
The complete question is shown on the first uploaded image
Answer:
The score of the student is x = 779.42
Step-by-step explanation:
Generally we can mathematically represent the z-score as
[tex]z = \frac{x - Mean}{ stDev}[/tex]
Here x is the score of the student
substituting 1045.7 for the Mean, 221.9 for the stDev and -1.2 for z we have
[tex]-1.2 = \frac{x - 1045.7 }{ 221.9}[/tex]
=> [tex]-266.28 = x -1045.7[/tex]
=> x = -266.28 + 1045.7
=> x = 779.42
The student scored 779.42 for him to have a z score of - 1.2;
z score is used to determine by how many standard deviations the raw score is above or below the mean.
The z score is given by:
[tex]z=\frac{x-\mu}{\sigma/ } \\\\where\ x\ is\ raw\ score,\mu\ is\ mean, \sigma\ is\ standard\ deviation[/tex]
Given that μ = 1045.7, σ = 221.9 Hence for z = -1.2:
[tex]-1.2=\frac{x-1045.7}{221.9} \\\\x=779.42[/tex]
The student scored 779.42 for him to have a z score of - 1.2;

The graph of a function g is a transformation of the graph of f(x)=4x−10, where g(x) is 40% of f(x). Write a rule for g.
Answer:
g(x) = 1.6 x - 4
Step-by-step explanation:
Given:
f(x) = 4 x - 10
g(x) is 40% of f(x)
Find:
g(x)
Computation:
⇒ g(x) = 40%[f(x)]
⇒ g(x) = 40%[4 x - 10]
g(x) = 1.6 x - 4

Solve that for me pls I’m writing here because I need twenty words
Answer:
k = 168
Step-by-step explanation:
[tex]4= \frac{k}{42}[/tex] rewrite the equation
[tex]42 * 4=\frac{k}{42} *42[/tex] Multiply 42 to isolate k. Do the same on the other side
42 * 4 = 168 When you do that you get 168.

The layout for European license plates is XXX – XXXX. The first three digits are letters and the last four are numbers. The exclusions on the plates are that the first three letters cannot be the same (i.e. AAA) and the last four cannot be the same (i.e. 1111). How many different possible plates can be made? Show all work and explanations necessary.
Answer:
No. of Plates Possible = 78624000 = 7.86 x 10⁷
Step-by-step explanation:
We have total 7 places to fill in order to form a plate. So, we see all the number of options available for each of the position:
No. of Options for First Place = 26 (All alphabets of English)
No. of Options for Second Place = 25 (Due to no repetition)
No. of Options for Third Place = 24 (Due to no repetition)
No. of Options for Fourth Place = 10 (Digits from 0 to 9)
No. of Options for Fifth Place = 9 (Due to no repetition)
No. of Options for Sixth Place = 8 (Due to no repetition)
No. of Options for Seventh Place = 7 (Due to no repetition)
Hence, the total possible plates that can be made are given by multiplying
the options to select in each place:
No. of Plates Possible = 26*25*24*10*9*8*7
No. of Plates Possible = 78624000 = 7.86 x 10⁷

You are setting up a part-time business with an initial investment of $12,000. The unit cost of the product is $11.50, and the selling price is $19.00.Required:a. Find equations for the total cost C (in dollars) and total revenue R (in dollars) for x units.b. Find the break-even point by finding the point of intersection of the cost and revenue equations units.c. How many units would yield a profit of $1000?
Answer:
Given Initial investment = $12,000
Cost per unit = $11.50
Selling price per unit = $19
a. For x unit
Total cost = Initial investment + Cost per unit * no of unit
= 12,000 + 11.50(x)
c(x) = 12,000 + 11.50(x)
R(x) = Selling price per unit * no of items
R(x) = 19 * x
R(x) = 19x
b. Break even point = R(x) = C(x)
19x = 12,000 + 11.50x
19x - 11.5x = 12,000
7.5x = 12,000
x = 12,000 / 7.5
x = 1600
So, break even point x = 1,600
c. For Profit = $1,000
P(x) = 1,000
P(x) = R(x) - C(x)
1000 = 19x - (12,000 + 11.5x)
1000 =19x - 11.5x - 12000
7.5x = 12000 + 1000
7.5x = 13000
x = 13000/7.5
x = 1733.33
So x = 1733 units
Hence, 1733 units will yield for $1,000 profit

The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.
Speed :The speed is the distance travelled per unit of time by a sound wave
Given informationSpeed of sound in water is [tex]1.46 \cdot 10^3[/tex]
Speed of sound in air is [tex]3.31 \cdot 10^2[/tex]
To find how much faster does travel , we need to subtract the speed
To subtract we need to make the exponents same
[tex]1.46 \cdot 10^3\\14.6 \cdot 10^2[/tex]
Now we subtract ,
[tex]14.6- 3.31= 11.29\\\\11.29 \cdot 10^2\\1.129 \cdot 10^3[/tex]
The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.

Chloe's college raises the cost of room and board per semester. This increase raises Chloe's opportunity cost of attending college
Answer:
The answer is "Option C"
Step-by-step explanation:
The choices were missing in the question, which is defined in the attached file please find it.
To attend university, Chole should pay the cost of a room and board each semester. Even though the Chole will not be in college, she will still have a room as well as a board and continue living.
If she will not attend college, it also has to equate rooms and board costs per six months since increase towards the room or board charges. If there's an increase in rooms and boarding costs because she did not understand below the rise in their school fees, therefore the financial cost reduces that desire of she attend.1/4n - 5 - 4n + 3 = 2

After 8 hours of snow, the temperature had changed by a total of -16 degrees. What was the average change in temperature each hour while it was snowing?
Answer:
-2 degrees
Step-by-step explanation:
Divide -16 by 8:
-16/8
= -2
So, the average change in temperature each hour was -2 degrees.
The average change of weather dropped 2 degrees for every hour is snowed.
Here,
After 8 hours of snow, the temperature had changed by a total of -16 degrees.
We have to find the average change in temperature in each hour.
What is Average?
Average is the middle value of the given sets of values.
Now,
After 8 hours of snow, the temperature had changed by a total of -16 degrees.
Hence, The average change in temperature in each hour = -16 ÷ 8 = -2
