On a recent quiz, the class mean was 69 with a standard deviation of 4.8. Calculate the z score for a person who received score of 74. z score:
Answer:
1.04167
Step-by-step explanation:
Z -score formula is given as
z = (x-μ)/σ, where
x is the raw score = 74
μ is the population mean = 69
σ is the population standard deviation = 4.8
Z score = x - μ/ σ
= 74 - 69/4.8
= 1.04167
The z score for a person is given as 1.04167

Answer:
[tex]a = 9in[/tex]
Step-by-step explanation:
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex] {a}^{2} = {c}^{2} - {b}^{2} [/tex]
[tex]a = \sqrt{ {c}^{2} - {b}^{2} } [/tex]
[tex]a = \sqrt{ {10.6}^{2} - {5.6}^{2} } [/tex]
[tex]a = \sqrt{112.36 - 31.36} [/tex]
[tex]a = \sqrt{81} [/tex]
[tex]a = 9in[/tex]

a college says it admits only people with sat scores among the top 10%. how high an sat score does it take to be g
Full question:
Suppose SAT scores among students are normally distributed with a mean of 500 and a standard deviation of 100.
If a college says it admits only people with sat scores among the top 10%. how high a sat score does it take to be eligible?
Answer and explanation:
To find where SAT score of student falls in the test given mean and standard deviation of scores, we can calculate: x-500/100 where x is number of SAT score of students
A sat score in the top 10% region would have a score better than 90% of other SAT scores. Therefore 0.90 has a z score of 1.28
We use algebra to find the score to be eligible thus:
1.28=x-500/100
x-500=128
x=128+500
x=628
Therefore to be eligible, a student needs to score at least 628, and be in the top 10% of scores

find the value of r so that the line through (8 r) and (4 5) has a slope of -4
Answer:
r = -11
Step-by-step explanation:
slope formula: (y2-y1)/(x2-x1) = slope
(5-r)/(4-8) = -4
(5-r)/ -4 = -4
5-r = 16
-r = 11
r = -11
im not sure but i beleive this is how you do it.
you find the agreegable slope, and then multiply it by the y value.
hope this helps! :)

Expression equivalent to 8p-3n+4q-9m
Answer:
4p-n+2q-3m is equivalent to 8p-3n+4q-9m
The expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression. which is the correct answer would be an option (C).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given in the question following:
8p - 3n + 4q - 9m
We have to determine the equivalent expression to the given expression
As per option (C), we have
⇒ 4(2p+ q) - 3(n+3m)
Apply the distributive property of multiplication,
⇒ 4 × 2p+ 4 × q - 3 × n + 3 × m
⇒ 8p + 4q - 3n + 3m
Rearrange the terms in the above expression,
⇒ 8p - 3n + 4q - 9m
So this expression is the same as the given expression.
Therefore, the expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression.

In ΔCAB, if m∠A = 10x + 9, m∠B = 34°, and m∠C = 97°, what is the value of x?
triangle CAB, point E is on segment AC between points A and C and point D is on segment BC between points B and C, creating segment ED
x = 2
x = 3
x = 4
x = 5
Answer:
x = 4
Step-by-step explanation:
(10x + 9) + 34 + 97 = 180
10x +140 = 180
10x = 40
x = 4
The value of x in the given angles of the traingle CAB for angle m∠A is determined as 4.
Sum of angles in a triangleThe sum of angles in a triangle can be used to determine the value of x in the given angles above.
m∠A + m∠B + m∠C = 180 (sum of angles in a triangle)
10x + 9 + 34 + 97 = 180
10x + 140 = 180
10x = 40
divide both sides by 10;
x = 40/10
x = 4
Thus, the value of x in the given angles of the traingle CAB for angle m∠A is determined as 4.

You randomly choose a ball. What is the sample space?
OA. (RG, Y, B, O)
OB. (R,G, Y, B, P)
Oc. (G, )
OD. (R, G, Y, B)
Answer: R,G,Y,B,O
Step-by-step explanation: Sample space is just any and all possible outcomes
The sample space of the given experiment is (R,G, Y, B, O). So option A is the correct one.
What is a Sample Space?A sample space is a set of all the possible outcomes in a random experiment. It is usually denoted by the letter, S.
The subset of the sample space are events.
Given experiment is that you randomly choose a ball from a bag which consists of 5 balls.
Balls are 1 red (R), 1 green (G), 1 yellow (Y), 1 blue (B), and 1 orange (O).
Each ball is of different color.
When you randomly choose a ball, the chosen ball can be any of the colors given.
So sample space = (R,G, Y, B, O)
Hence the required sample space is (R,G, Y, B, O).

ASAP need answer to this system of equations... ILL give brainliest to correct answers only
Answer:
(7,12),(-12,-7)
Step-by-step explanation:
x^2 + y^2 = 193
x - y = - 5
x = y - 5
(y - 5)^2 + y^2 = 193
y^2 - 10y + 25 + y^2 = 193
2y^2 - 10y + 25 = 193
2y^2 - 10y + 25 - 193 = 0
2y^2 - 10y - 168 = 0
2*(y^2 - 5y - 84) = 0 This factors into
2*( y - 12) (y + 7) = 0
y = 12
in which case x = 12 - 5 = 7
y = - 7
in which case x = -7 - 5 = - 12
