Answer:
1,888 pencils
Step-by-step explanation:
Answer:
h less-than 2
Step-by-step explanation:
Let
h ---> the number of hours
y ---> the total charge in dollars
we know that
The linear equation is slope intercept form is equal to
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
we have
<em>Grayson</em>
The slope is equal to
The y-intercept is
so
The total charge is equal to
----> equation A
<em>Ian</em>
The slope is equal to
The y-intercept is
so
The total charge is equal to
----> equation B
For what number of hours does Grayson charge more than Ian?
The inequality that represent this situation is
solve for x
Group terms
Divide by 10 both sides
Rewrite the expression
----> h less than 2 hours
0.4 per 1 minute = 0.4/1.
Answer:
a measure of central tendency
Step-by-step explanation:
The mode of a given data set is a measure of central tendency.
Statistical tools are usually classified as either a measure of central tendency or a measure of dispersion.
A measure of central tendency is a parameter that tends to determine how close a data is to the center. These parameters are mean, median and mode
A measure of dispersion measures how spread a data set is from the mean. These parameters are standard deviation, variance e.t.c
A=2B
B=B
C=A-2=2B-2
A+B+C=98
5B-2=98
5B=100
B=20
Thus A= 2B = 40
C=38
Nothing much wrong only calculation mistakes
