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.

Positive x coordinate and a negative y coordinate.
Quadrant III has a negative x coordinate and negative y coordinate, so A. is incorrect.
It is not B. because it is not on the y-axis.
Quadrant IV has a positive x coordinate and a negative y coordinate, so C. is correct.
Quadrant II has a negative x coordinate and a positive y coordinate so D. is incorrect.

Based on the line of best fit, what is the predicted
height for someone with a first metacarpal bone
that has a length of 4.45 centimeters?
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.

Answer:
x is on the right side of the triangle
Step-by-step explanation:
Answer:
x = 28.8
Step-by-step explanation:
[tex]\frac{12}{25}[/tex] = [tex]\frac{x}{60}[/tex]
then cross multiply
25x = 720
then divide 25 from both sides of the equation
x = 28.8
What is the difference between a population characteristic and a sample statistic?
engage
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.

Eric bought a packet of toffees for his friend. The packet had 2/6 of a pound of toffee. He broke the toffee into 7 equal paper baggies. What is the weight of one of those baggies
Answer:
1 / 21 pound
Step-by-step explanation:
Weight of toffee in a packet = 2/6 pounds
Toffee is broken into 7 equal baggies ;
Weight of one of the baggies :
Weight of toffee before being broken / number of division
= 2/6 ÷ 7
= 2/6 * 1/7
= 2 / 42
= 1/21 pounds

Step-by-step explanation:
A hockey goalie is paid $500 per game, less $45 for each goal he allows to score. Write an algebraic expression that would equal how much he gets paid in a game
Answer:
x=500+45y
Step-by-step explanation:
From the information given, the algebraic expression that would equal how much he gets paid in a game would be the amount that the hockey golie is paid per game minus the result of multiplying $45 for the number of goals he allows to score. According to this, the expression is:
x=500+45y, where x is the amount the hockey goalie gets paid in a game and y is the number of goals he allows to score.
