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

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 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 baseball coach collected data to analyze the free throw shooting percentages of players during a game and during practice. The equation y=0.9x-1 is a line of best fit for the data, where x is the practice shooting percentage and y is the game shooting percentage. Based on the equation, what will be the approximate shooting percentage in a game for a player with a practice shooting percentage of 88?
Step-by-step explanation:
so fill in 88 where the x is so
y = 0.9 (88) - 1
y = 78.2

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°

A= B= b= what’s the answer i been trying to solve all day
Answer:
Step-by-step explanation:
We are given the triangle ABC and told to find ∠A, ∠B, and side b. Also we are told that side c= 54 . side a=64 and ∠C = 32°
we need law of sines a / sin A = b / sin B = c / sin C
let's use law of sines to find the other angles
64 / sin A = 54 / sin(32)
I'm just going to swap the fractions on both sides , just to make it easier
sin A / 64 = sin(32) / 54
∠A = arcSin(64 * sin(32) / 54)
∠A = 38.9066°
∠B + ∠A + ∠C = 180
∠B = 180 - 32 - 38.9066
∠B = 109.0934°
let's find side b now
sin B / b = sin(32) / 54
sin(109.0934°) / b = sin(32) / 54
54 * sin(109.0934°) / sin(32) = b
96.2963 = b

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.
