Answers
Answer:
x = 5, AB = 27, BC = 19
Step-by-step explanation:
From the diagram
AB + BC = AC , substitute values
4x + 7 + 3x + 4 = 46 , that is
7x + 11 = 46 ( subtract 11 from both sides )
7x = 35 ( divide both sides by 7 )
x = 5
Thus
AB = 4x + 7 = 4(5) + 7 = 20 + 7 = 27
BC = 3x + 4 = 3(5) + 4 = 15 + 4 = 19
Answer:
1. x = 5
2. AB= 27
3. BC = 19
Step-by-step explanation:
Solving for X:
The entire segment is 46. Parts AB and BC make up the whole thing. So, to find x, add both expressions and set them equal to 46.
4x+7+3x+4=46 (combine like terms)
7x+11=46 (subtract 11 from both sides)
7x = 35 (divide by 7)
x = 5
Finding AB:
Plug 5 in for x and evaluate the expression.
4(5)+7
20 + 7= 20
AB is 27
Finding BC:
Plug in 5 for x and evaluate the expression.
3(5)+4
15+ 4=19
Check your work.
Add the values of AB and BC to make sure they add up to 46, which is AC.
27 + 19 = 46, so this is correct.

The results of a recent survey showed that the average cost to rent a car for a week is $276. If the standard deviation is $60,
find the Z-score for a weekly rental of $423.00?
a. 2.45
B. 4.6
C. 7.05
D. -1.88
Answers
I divided 276/60 and got b
The Z-score for a weekly rental is 2.45 which is the correct answer would be option (B).
What is Z -score?A Z-score is defined as the fractional representation of data point to the mean using standard deviations.
Given the average cost to rent a car for a week is $276
And the standard deviation is $60
To determine the Z-score for a weekly rental of $423.00
Here,
ц = 276
σ = 60
X = 423
⇒ z-score = (X-ц )/σ
Substitute the values,
⇒ z-score = (423 - 276)/60
⇒ z-score = 147/60
⇒ z-score = 2.45
Hence, the z-score for a weekly rental is 2.45.

11 students in the Environmental club represent 4% of the students in the seventh grade. How many students are in the seventh grade?
Answers
Answer:
275
Step-by-step explanation:
The best way to do this is to set it up in this equation:
4/100 = 11/x, in this, the 4 over 100 represents 4% out of 100%. The 11 over x represents the 11 students out of x amount of students. With this equation, you cross multiply to get 4x = 1100. Then you divide both sides by 4 to get x by itself. This will give you x=275
After solving the equation, the total number of students in the 7th grade is 275.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the data mentioned in the question,
Total number of students in the Environmental club = 11
Percentage of students from 7th grade = 4%
Let the total number of students in 7th grade be x
Then, the equation according to the statement will be,
4% of x = 11
So,
x = (11 × 100)/4
x = 275

Select the correct answer. What is the solution to the equation |5 − x| = 13? A. x = -8 or x = 18 B. x = -18 or x = 8 C. x = 8 D. x = -18
Answers
Answer: A) X = -8 or X = 18
Step-by-step explanation:
Since we're dealing with absolute value, there are going to be two different solutions to this equation.
5 - x = 13
-x = 8
x = -8
OR
5 -x = -13 ( the negative is from the absolute value)
-x = - 18
x= 18
The value of x is either -8 or 18 (option A)
What is an equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
Given is an equation, |5-x| = 13
Solving the equation,
|5-x| = 13
When we will remove the modulus, we will get two conditions,
5-x = 13 or 5-x = -13
Solving both one by one,
5-x = 13
x = -8
And,
5-x = -13
x = 18
Hence, the value of x is either -8 or 18

Answers
Answer:
The output is 65 when x is -10.
Step-by-step explanation:
y=mx+b is the easiest form to understand visually what the slope and intercept is.
m is the slope and b is the y-intercept. Replace both of these variables respectively with their appropriate values. In this case, the slope (m) is -5 and y-intercept is 15.
Equation looks like this: y=-5x+15
What is the output when x is -10? Replace x with 10, and your output is the y value.

Consider a system with sampling rate 52,500 samples per second.
(a) Determinethe maximum frequency of the pre-sampled signal if the system utilizes 18% oversampling.
(b) Determine the percentage oversampling if the maximum frequency from part (a) isincreased by 10%.

Answer:
The answer is "[tex]22,246 \ H_z \ \ and \ \ 7.3\%[/tex]"
Step-by-step explanation:
The sampling rate: [tex](f_s) = 52,500 \ \frac{samples}{sec}[/tex]
In point a:
The sample signal frequency = f
They recognize that the id [tex]\geq[/tex] 2f sampling frequency could be returned to its original signal unless the aliase effect is detected elsewhere, Yet under percentage =18%
[tex]\ sampling \ rate = 2 \times 1.18 \times f[/tex]
[tex]\to f = \frac{52,500}{2 \times 1.18}\\\\[/tex]
[tex]= 22,246 \ h_z[/tex]
In point b:
Maximum 22,242 frequency is increased by [tex]10 \ \%[/tex]
[tex]f_a =22,246 \times 1.1[/tex]
[tex]= 24,470.6\\\\=24,471[/tex]
[tex]\ sampling \ rate= x \times 2 \times 24,2471 \\[/tex]
[tex]x= \frac{52,500}{48,942} \\\\x= 1.073\\\\[/tex]
