Answer:
d = 4t + 60
Step-by-step explanation:
If Bryson jogged at a constant rate of constant speed and he starts a timer when he is 20 feet from his starting position. after 5 seconds, his speed will represent the slope of the required equation:
Speed = distance/time
Speed = 20 feet/ 5 secs
Speed = 4ft/s
Hence the slope of the equation is 4ft/s
Next is to get the intercept c
Standard equation that represents the expression is:
d = mt+c
d is the distance of bryson from his starting position
To get the intercept c, substitute d = 80, m = 4 and t = 5 into the equation as shown:
80 = 4(5) + c
80 = 20 +c
c = 80 - 20
c = 60
Get the equation:
Substitute m = 4 and c = 60 into the original equation
d = mt + c
d = 4t + 60
Hence a linear equation in slope-intercept form to find the distance d of bryson from his starting position after t second is d = 4t + 60

Coconuts were on sale, 4 for $4.44. Pineapples were on sale, 3 for $3,63. Which
of the following is true?
ОА.
1/6
Coconuts are 10¢ less each than pineapples,
Coconuts are 10¢ more each than pineapples,
B.
OC. Coconuts are each $1.21.
OD. Pineapples are each $1.11.
Answer:
The answer is Coconuts are 10 cents less than the pineapples.
Step-by-step explanation:
You had to find what each of them cost which was $1.11 for each coconuts and the pineapples were $1.21 each. Then you had to subtract to find the difference which was 10 cents. So since the pineapples were more, the answer was the coconuts were 10 cents less than the pineapples.
Coconuts: $4.44 ÷ 4 = $1.11 each Pineapple: $3.63 ÷ 3 = $1.21 each
1.21 - 1.11 = 10 cents
Solve for k. You may either explain each step of the process in the box below or attach a photo that shows your work in solving it.
4k + 13 = 3k + 5
it equals -8.
4k + 13 = 3k + 5
4k + 13 - 13 = 3k + 5 - 13
4k = 3k - 8
4 k − 3 k = 3k - 8 - 3k
k = -8

∴ 5 rings will cost 5 × $125
5 × $125 = $625
Hence, the total cost of the rings is $625
For the bracelets
From the question, a bracelet cost $88
∴ 9 bracelets will cost 9 × $88
9 × $88 = $792
Hence, the total cost of the bracelets is $792
The amount the store will take in will be $625 + $792 = $1417
Hence, if all 14 items sell, the amount of money the store will take in will be $1417.
The correct answer is A. $1,417 9 × $88 = $792; 5 × $125 = $625; $792 + $625 = $1,417

Answer: SEE EXPLANATION!
Step-by-step explanation:
Population Parameters versus Sample Statistics
A parameter is a value that describes a characteristic of an entire population, such as the population mean. ... A statistic is a characteristic of a sample. If you collect a sample and calculate the mean and standard deviation, these are sample statistics.
The difference between Population characteristic and Sample statistic is discussed below.
What is Statistic?Statistics is a branch of applied mathematics that allows us to collect, describe and analyze the given set of data in order to make inference of conclusions on the given data set.
Given are two terms as population characteristic and a sample statistic.
Population characteristic refers to the characterization of various types of populations within a social or geographic group, with emphasis on demography, health status, and socio-economic factors. There are various characteristics of a population such as population size and density, populace spatial dissemination, age structures, birth rate or Natality and mortality rate.
Sample statistic represents the calculation that you measure from a subset of a larger group (the population).There are 5 types of sampling - Systematic, random, convenience, cluster and stratified.
Therefore, the difference between Population characteristic and Sample statistic is discussed above.

There are 120 students in a school. In a survey of all students, 47 students support delaying the start of school, 53 students do not support delaying the start of school, and 20 students are indifferent to the school start time. If a student is selected at random, find the probability that the selected student is not indifferent to the school start time. Express your answer in simplified rational form.
Answer:
The probability that the selected student is not indifferent to the school start time is 0.8333.
Step-by-step explanation:
Define the events s follows:
X = students support delaying the start of school
Y = students do not support delaying the start of school
Z = students are indifferent to the school start time.
The events X, Y and Z are mutually exclusive events.
That is they cannot occur together.
Compute the probability that the selected student is not indifferent to the school start time as follows:
P (Z') = P (X or Y)
= P (X) + P (Y)
[tex]=\frac{47}{120}+\frac{53}{120}\\\\=\frac{47+53}{120}\\\\=0.8333[/tex]
Thus, the probability that the selected student is not indifferent to the school start time is 0.8333.

A)168 centimeters
B) 169 centimeters
C) 170 centimeters
D) 171 centimeters
Answer:
C) 170 centimeters
Step-by-step explanation:
The missing graph-diagram to the question is attached in the image below.
Using the line of best fit, the predicted height for someone with a first metacarpal bone that has a length of 4.45 centimeters can be determined as follows:
The length of 4.5 centimeters appears on the horizontal x-axis; This implies that 4.45 is a half distance between the undotted 4.4 centimeters and the dotted 4.5 centimeters. Similarly, on the vertical y-axis, 170 is directly equivalent to the dotted point of 4.5 centimeters. Thus, the predicted height with a 4.45 centimeters length is approximately 170 centimeters by using the line of best fit.

A rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. Six hundred feet of fencing is used. Find the dimensions of the playground that maximize the total enclosed area. What is the maximum area?
Answer:
the smallest dimension = 100 ft
the largest dimension = 150 ft
Maximum Area = 15000 ft²
Step-by-step explanation:
let x represent length of one side and L represent length of adjacent side
so from the question
3x + 2L = 600
2L = 600 - 3x
L = (600 - 3x)/2
L = (600/2) - (3x/2)
L = 300 - (3x/2)
now Area of rectangle = L × x
Area = (300 - (3x/2)) × x
Area = 300x - 3x²/2
now we differentiate with respect to x and equate to 0 in other to find critical point
dA/dx ⇒ 300x/x - 3x²/x = 0
300 - 3x = 0
3x = 300
x = 300/3
x = 100
so we input value of x into our previous equation
Area = 300x - 3x²/2
= 300(100) - (3(100)²)/2
= 30000 - 15000
Area = 15000
also we input value of x in L = 300 - (3x/2)
L = 300 - (3(100))/2)
L = 300 - 150
L = 150
Therefore
the smallest dimension = 100 ft
the largest dimension = 150 ft
Maximum Area = 15000 ft²
