Based on the data, how long do you predict baby Grace will be at 36 months of age? Use the rate of change to justify your answer. Does your answer make sense? Explain. (2 points)
Answers
The point-slope intercept equation is y - 20 = 3/4(x - 4).
The rate of change is 3/4.
At 0 months (at birth), Grace was 17 inches long.
At 36 months, Grace would be 44 inches long.
How to Create a Linear Equation?A linear equation of a graph can be represented in point-slope form as y - b = m(x - a), where (a, b) is a point on the graph and m is the slope.
Find the Slope (m) using two points (4, 20) and (8, 23):
Slope (m) = change in y/change in x = (23 - 20)/(8 - 4)
Slope (m) = 3/4
Substitute (a, b) = (4, 20) and m = 3/4 into y - b = m(x - a):
y - 20 = 3/4(x - 4) [point-slope intercept equation]
At birth, months would be x = 0. To find how long Grace was at birth, substitute x = 0 into y - 20 = 3/4(x - 4) to find the value of y:
y - 20 = 3/4(0 - 4)
y - 20 = 3/4(-4)
y - 20 = -3
y - 20 + 20 = -3 + 20
y = 17
This means that, at 0 months (at birth), Grace was 17 inches long.
At 36 months, substitute x = 36 into y - 20 = 3/4(x - 4) to find the how long Grace was (y):
y - 20 = 3/4(36 - 4)
y - 20 = 3/4(32)
y - 20 = 24
y - 20 + 20 = 24 + 20
y = 44
At 36 months, Grace would be 44 inches long.

In an examination given to a class of 20 students, the following test scores were obtained.
45 45 50 50 55 60 70 75 75 80
80 85 85 85 85 90 95 95 95 100
a) Find the mean (or average) score, the mode, and the median score.
b) Which of these three measures of central tendency do you think is the least representative of the set of scores?
Answers
Answer:
Mean = 75
Median = 80
Mode = 85
The mode
Step-by-step explanation:
Given the data :
45 45 50 50 55 60 70 75 75 80 80 85 85 85 85 90 95 95 95 100
Rearranged data :
45, 45, 50, 50, 55, 60, 70, 75, 75, 80, 80, 85, 85, 85, 85, 90, 95, 95, 95, 100
The mean score :
ΣX / n ; n = sample size = 20
ΣX = 1500
Mean = 1500 / 20 = 75
Mode = most frequently occurring = 85 ( frequency of 4)
Median = 0.5(n + 1)th term
Median = 0.5(20 + 1)th term
Median = 0.5(21) th term
Median = 10.5th term = (10 + 11)th term / 2
Median = (80 + 80) / 2 = 160 / 2 = 80
2.) The mode

a man buys eggs at RS 9.60 per dozen and sell 20 eggs for RS 18 what is his gain or loss percen?
Answers
Answer:
88.89%
Step-by-step explanation:
Step one:
given
a man buys eggs at RS 9.60 per dozen
what is the unit cost of the dozen of eggs?
unit cost = 9.60/12
= $0.8 per egg
He sold 20 eggs for RS 18
the unit selling price = 18/20
=$0.9 per egg
the percent gain is
=0.8/0.9*100
=0.888*100
=88.89%
The bakers at Healthy Bakery can make 170 bagels in 2 hours. How many
bagels can they bake in 14 hours? What was that rate per hour?
Answers
Given:
The bakers at Healthy Bakery can make 170 bagels in 2 hours.
To find:
How many bagels can they bake in 14 hours and the rate per hour.
Solution:
We have,
Number of bagels the bakers can bake in 2 hours = 170 bagels
Number of bagels the bakers can bake in 1 hours = [tex]\dfrac{170}{2}[/tex] bagels
= 85 bagels
Therefore, the average rate is 85 bagels per hour.
Number of bagels the bakers can bake in 14 hours = [tex]14\times 85[/tex] bagels
= 1190 bagels
Therefore, the bakers can bake 1190 bagels in 14 hours.

What is the activity rate under activity-based costing?The activity rate under activity-based costing is also called the cost driver rate.
The activity rate per cool pool can be computed by dividing the cost pool total cost by the cost driver total requirements.

Suppose f(x)=x^2+9x+8
1. Suppose F(x) is obtained by reflecting the graph over the y-axis. Find a formula for F(x).
Suppose g(x)=x^19-8x^6-x^5+7x^2+x+9.
1. Reflected over x-axis vertically
2. Reflected over y-axis horizontally
Answers
Using translation concepts, the functions are given as follows:
1. F(x) = x² - 9x + 8.
2. [tex]G(x) = x^{19} + 8x^6 - x^5 - 7x^2 + x - 9[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
In item 1, the function is:
f(x) = x² + 9x + 8.
When the function is reflected over the y-axis, we have that:
F(x) = f(-x),
Hence:
F(x) = (-x)² + 9(-x) + 8.
F(x) = x² - 9x + 8.
For item 2, the function is:
[tex]g(x) = x^{19} - 8x^6 - x^5 + 7x^2 + x + 9[/tex]
When the function is reflected over the x-axis, we have that:
G(x) = -g(x).
Hence:
[tex]G(x) = -x^{19} + 8x^6 + x^5 - 7x^2 - x - 9[/tex]
When the function is reflected over the y-axis, we have that:
Hence:
G(x) = G(-x).
[tex]G(x) = -(-x)^{19} + 8(-x)^6 + (-x)^5 - 7(-x)^2 - (-x) - 9[/tex]
[tex]G(x) = x^{19} + 8x^6 - x^5 - 7x^2 + x - 9[/tex]
