Directions:Identify the constant used in the following algebraic expressions and
equations.Example:y=3x+2
Answer:
2
Step-by-step explanation:
Constants in an equation represents numbers. They are not attached to any variable. Given the equation y = 3x + 2, you will see that the term that is standing alone without a variable here is 2. This shows that the constant used in the equation is 2

The lateral surface area of a triangular prism is 120 in?. If the perimeter of the base is
20 inches, what is the height?
Answer:

Step-by-step explanation:
Consider the graph of f(x) = (1/2)x
The graph of function g is graph because the graph of function g is the result of a
applied to the graph of function f
The graph of function g is graph Z because the graph of function g is the result of a horizontal compression applied to the graph of function f
How to determine the function g(x)?Function f(x) is given as:
[tex]f(x) = (\frac 12)^x[/tex]
Function g(x) is given as:
g(x) = f(kx)
The above represents a horizontal compression of function f(x) to form function g(x)
The graph that represents a horizontal compression is graph Z
Hence, the graph of function g is graph Z

nearest hundredth.
A

in
Answer:
94.99
Step-by-step explanation:
Hi,
The formula to find the area of a circle is: A = πr²
So...
A = 3.14 (r)²
The radius of the circle is 5.5 because half of the diameter is the radius.
A = 3.14 (5.5)²
A = 3.14 (30.25)
A = 94.985 rounded is 94.99

Frequency refers to the number of times an event or value occurs. A frequency table is a table that lists items and shows how many times those items occurred.
A line plot displays the data using a no. line.
Firstly, we will fimd the frequency of each value
Values Frequency
9 (7/8) 1
10(4/8)=10(1/2) 1
10(5/8) 1
10(6/8)=10(3/4) 1
10(7/8) 1
11(2/8)=11(1/4) 3
Option A is incorrect because 11(2/8) has no data values in the line plot (i.e. frequency = 0)
Option B is incorrect because 11(2/8) has no data values in the line plot (i.e. frequency = 0)
Option C is correct because the frequency distribution of the data is represented correctly in the line plot.
Option D is incorrect because 11(2/8) has 2 data values in the line plot (i.e., frequency = 2)
Hence, the line plot which correct shows the data is third line plot.

For f(x) = 5x – 3 and g(x) = 2x2 - 5, find the following functions.
a. (fog)(x); b. (gof)(x); c. (fog)(2); d. (gof)(2)
Answer:
See answer below
Step-by-step explanation:
Given the functions f(x) = 5x – 3 and g(x) = 2x2 - 5, find the following functions.
a)(fog)(x) = f(g(x))
f(g(x)) = f(2x^2-5)
f(g(x)) = 5(2x^2-5) - 3
f(g(x)) = 10x²-25-3
f(g(x)) = 10x² - 28
b) g(f(x)) = g(5x-3)
g(f(x)) = 2(5x-3)²-5
g(f(x)) = 2(25x²-30x+9)-5
g(f(x)) = 50x²-60x+18-5
g(f(x)) = 50x²-60x+13
c)(fog)(2) = f(g(2))
f(g(x)) = f(2x^2-5)
f(g(2)) = 10(2)² - 28
f(g(2)) = 10(4)-28
f(g(2)) = 12
d) g(f(x)) = g(5x-3)
g(f(x)) = 2(5x-3)²-5
g(f(x)) = 50x²-60x+13
g(f(2)) = 50(2)²-60(2)+13
g(f(2)) = 200-120+12
g(f(2)) =80+12
g(f(2)) = 92

The following set of data represents the age in years of newly married ladies in Desai. 15,25,17,20,22,24,19,16./ This data was collected after Deborah made an allegation that ladies in Desai get married at an age other than 18 years as is required by law. Does this data provide enough evidence at 5% level of significance to believe that the mean ages of ladies getting married in Desai is actually different from 18 years as claimed by Deborah?
Answer:
There is no significant evidence to conclude that the mean ages of ladies getting married in Desai is different from 18.
Step-by-step explanation:
Given the data:
15,25,17,20,22,24,19,16
Using calculator :
Mean value, xbar = 19.75
Standard deviation, s = 3.69
Samoke size, n
H0 : μ = 18
H1 : μ > 18
The test statistic :
Tstatistic = (xbar - μ) ÷ (s / sqrt(n))
Test statistic = (19.75 - 18) ÷ 3.69/ sqrt(8))
Test statistic = 1.75 ÷ 1.3046
Test statistic = 1.34
The Pvalue from test statistic ; df = n - 1 = 8 - 1 = 7
Pvalue = 0.111054
Decision :
If Pvalue < α ; reject H0
0.111053 > 0.05 ` Hence, we fail to reject H0
We can conclude that, There is no significant evidence to conclude that the mean ages of ladies getting married in Desai is different from 18.

a. What the relationship between Z BEC and Z BAC?
b. What the measure of ZBEC ?
c. What the measure of BDC ?
Answer:
A) ∠BEC is one-half of ∠BAC
B) ∠BEC = 60°
C) ∠BDC = 120°
Step-by-step explanation:
C) arc BDC = 120°
arc BEC = 360° - 120° = 240°
∠BDC = 1/2(240°) = 120°
Manufacture of a certain component requires three different machining operations. Machining time for each operation has a normal distribution, and the three times are independent of one another. The mean values are 20, 15, and 30 min, respectively, and the standard deviations are 1, 2, and 1.5 min, respectively. What is the probability that it takes at most 1 hour of machining time to produce a randomly selected component
Answer:
0.0314 = 3.14% probability that it takes at most 1 hour of machining time to produce a randomly selected component
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Sum of normal variables:
When normal variables are added, the mean is the sum of the means while the standard deviation is the square root of the sum of the variances.
The mean values are 20, 15, and 30 min, respectively:
This means that [tex]\mu = 20 + 15 + 30 = 65[/tex]
The standard deviations are 1, 2, and 1.5 min, respectively.
This means that [tex]\sigma = \sqrt{1^2 + 2^2 + 1.5^2} = 2.6926[/tex]
What is the probability that it takes at most 1 hour of machining time to produce a randomly selected component?
Mean and standard deviation are in minutes, so this is the pvalue of Z when X = 60.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{60 - 65}{2.6926}[/tex]
[tex]Z = -1.86[/tex]
[tex]Z = -1.86[/tex] has a pvalue of 0.0314
0.0314 = 3.14% probability that it takes at most 1 hour of machining time to produce a randomly selected component
Use the ALEKS calculator to find 35% of 65. Do not round your answer.
Answer:
