In order to help students improve their reading, a school district decides to implement a reading program. It is to be administered to the bottom 5% of the students in the district, based on the scores on a reading achievement exam. If the average score for the students in the district is 122.6, find the cutoff score that will make a student eligible for the program. The standard deviation is 18. Assume the variable is normally distributed. Round to two decimal places.
Answer:
92.99
Step-by-step explanation:
Mean, μ = 122.6
Standard deviation, σ = 18
Recall :
Z = (x - μ) / σ
x = score
The Zscore for the lower 5% = 0.05
Using, invnorm(0.05) = - 1.645
Put Z = - 1.645
-1.645 = (x - 122.6) / 18
-1.645 * 18 = x - 122.6
-29.61 = x - 122.6
-29.61 + 122.6 = x
x = 92.99
Point O is the center of the circle. Determine the m BD.
To Find :
Angle of the arc BD.
Solution :
From the given figure, ∠BOC = 90°.
∠COD = 120°.
Now, we know, a full circle is, 360°.
So, ∠BOC + ∠COD + ∠BOD = 360°
90° + 120° + ∠BOD = 360°
∠BOD = 150°
Hence, this is the required solution.

If someone watching at movie that was 2 hours and 35 minutes long and finished watching at 5:30pm .What time did the movie began
Answer: 2:55 PM
Step-by-step explanation:
Given
The length of the movie is 2 hour and 35 minutes
If the movie is finished at 5:30 PM
First, subtract 2 hours from the finishing time i.e.
[tex]=5:30\ \text{PM}-2\ \text{hr}\\=3:30\ \text{PM}[/tex]
Now, subtract 35 minutes into two parts i.e. 30 min and 5 min from 3:30 PM
[tex]=3:30\ \text{PM}-30\ \text{min}\\=3:00\ \text{PM}[/tex]
remaining 5 min
[tex]=3:00\ \text{PM}-05\ \text{min}\\=2:55\ \text{PM}[/tex]
Thus, the starting time is 2:55 PM

Consider functions f and g.
Which expression is equal to f(x) ⋅ g(x) ?
Answer:
C
x-2 / x+6
Step-by-step explanation:
I did the math
(I am not 100% sure though, so if I am wrong, someone please mention it!)
The function f(x) . g(x) is a composite function, and the value of f(x) . g(x) is (x- 2)/(x + 6)
What is a composite function?A composite function is a function formed by combining multiple independent functions
The functions f(x) and g(x) are given as:
[tex]f(x) = \frac{x + 12}{x^2 + 4x- 12}[/tex]
[tex]g(x) = \frac{4x^2 - 16x+ 16}{4x+ 48}[/tex]
The composite function f(x) . g(x) is calculated using:
[tex]f(x) \cdot g(x) =\frac{x + 12}{x^2 + 4x- 12} * \frac{4x^2 - 16x+ 16}{4x+ 48}[/tex]
Expand the functions
[tex]f(x) \cdot g(x) =\frac{x + 12}{x^2 + 4x- 12} * \frac{4(x^2 - 4x+ 4)}{4(x+ 12)}[/tex]
Cancel out the common factors
[tex]f(x) \cdot g(x) =\frac{1}{x^2 + 4x- 12} * \frac{x^2 - 4x+ 4}{1}[/tex]
Further, expand
[tex]f(x) \cdot g(x) =\frac{1}{(x -2)(x + 6)} * \frac{(x - 2)(x - 2)}{1}[/tex]
Cancel the common factors
[tex]f(x) \cdot g(x) =\frac{x- 2}{x + 6}[/tex]
Hence, the value of f(x) . g(x) is (x- 2)/(x + 6)

8.92 kilograms equal how many decigrams
Answer:
89200
Step-by-step explanation:
One side of right angled triangle is 10 cm the other are both of length x ,calculate x to 2 decimal places
As triangle is right angled, we can possibly use the Pythagoras theroam.
By pythgoras theoram;
= H² = B² + P²
= 10² = x² + x²
= 10² = x⁴
=⁴√ 10² = x
= 10²×¼ = x
= 10½ = x
= √10 = x
= 3.16 = x
So the value of x is 3.16 cm
(Hypotenuse)² = (Base)²+ (Perpendicular)²
Taking, Hypotenuse As H
Base As B
Perpendicular As P
_________________________
Solving The QuestionH= 10cm
B= x cm
P= x cm
__________
H²= B²+P²
10²= x²+x²
=> 100= 2x²
=> √100= 2x
=> 10=2x
=> x=10/2
=> x= 5
Hope This Helps You ❤️5. Miguel has an after-school job. He works
between 15 and 25 hours each week and is paid
$12 per hour. What is an appropriate domain for
this scenario?
A. All real numbers such that 15
B. All real numbers such that 180 < x < 300
C. All real numbers
D. All real numbers such that x>0
Answer:
The domain is 15 ≤ x ≤ 25
Step-by-step explanation:
The given parameters are;
The number of hours Miguel works each week = Between 15 and 25 hours
The amount he is paid per hour = $12
Therefore, we have;
The domain is all real numbers, 'x', such that 15 ≤ x ≤ 25
The amount Miguel makes each week, 'y' is between; 12 × 15 ≤ A ≤ 12 × 25
Therefore the range is 180 ≤ y ≤ 300.

Answer:
480 in²
Step-by-step explanation:
The Pythagorean Theorem is a²+b²=c², where "a" and "b" are side lengths of a right triangle, and c is the hypotenuse of the right triangle. We are given a side length of 30 inches and a hypotenuse of 34 inches, which will be "a" and "c" respectively. Therefore, we can solve for b, the missing side length:
a²+b²=c²
30²+b²=34²
900+b²=1156
b²=256
b=16
Therefore, the missing side length is 16 inches, making the area of the triangle A=bh=(30)(16)=480 in².
Answer:
The area is 240

Give the following sequence for f(x) = 4x^2 - x , when x is -4, 1, 2
O 58, 14, 3
0-64, - 14, 3
O 68, 14, 3
0 7, 14, 3
Answer:
O 68, 14, 3
Step-by-step explanation:
Given:
f(x) = 4x² - x
When x = -4
f(x) = 4x² - x
= 4(-4)² - (-4)
= 4(16) + 4
= 64 + 4
f(x) = 68
When x = 1
f(x) = 4x² - x
= 4(1)² - 1
= 4(1) - 1
= 4 - 1
f(x) = 3
When x = 2
f(x) = 4x² - x
= 4(2)² - 2
= 4(4) - 2
= 16 - 2
f(x) = 14
The answer = 68, 3, 14

Suppose that AKL M is isosceles with base MK.
Suppose also that m 2 M= (3x+36) and m 2 K = (4x +31)
Find the degree measure of each angle in the triangle.
m ZK = 0
m 2L =
m ZM =
MA
K
(3x +36)
(4x +31).
Х
Answer:
m<K = 51°
m<L = 78°
m<M = 51°
Step-by-step explanation:
Base angles of an isosceles ∆ are equal to each other, therefore,
m<M = m<K
Substitute
3x + 36 = 4x + 31
Collect like terms and solve for x
3x - 4x = -36 + 31
-x = -5
Divide both sides by -1
x = 5
Let's find each degree measure using the value of x
m<K = 4x + 31
Plug in the value of x
m<K = 4(5) + 31
m<K = 20 + 31
m<K = 51°
m<M = 3x + 36
= 3(5) + 36
= 15 + 36
m<M = 51°
m<L = 180° - (m<M + m<K) (sum of triangle theorem)
Substitute
m<L = 180 - (51 + 51)
m<L = 78°

Answer:

Step-by-step explanation:
The absolute value function makes no change to a non-negative argument. Here, the argument (x+3) will be non-negative when ...
x + 3 ≥ 0
x ≥ -3 . . . . . . condition for the first line
__
When the argument is negative, the absolute value function multiplies it by -1. So the function on the second line is ...
-1(x+3) = -x -3
and the condition on the second line is ...
(x +3) < 0
x < -3 . . . . . condition on the second line
