Answer:
85+x=153
Step-by-step explanation:
So basically, Victor made an unknown amount of snowballs after lunch, and you need to find the amount. You can represent the unknown as the variable x. Then, you get the equation 85+x=153
The equation used to find the number of snowballs s Victor and his friends make after lunch is s + 85 = 153.
Given data:
Victor and his friends are preparing for an epic snowball fight. They make 85 snowballs before Victor's dad calls them in for lunch. After lunch, they make more snowballs. In all, Victor and his friends make 153 snowballs.
Now , the equation to find the number of snowballs Victor and his friends make after lunch is determined as :
s + 85 = 153
In this equation, "s" represents the number of snowballs they make after lunch. The equation states that the sum of the snowballs made before lunch ("85") and the snowballs made after lunch ("s") is equal to the total number of snowballs they made ("153").
Hence, the equation is s + 85 = 153

Which statement best describes how she should draw her line of best fit? A. The line of best fit will be horizontal. B. The line of best fit will be vertical. C. The line of best fit will increase from left to right. D. The line of best fit will decrease from left to right.
Answer:
B
Step-by-step explanation:
The line of best fit should be vertical. This answer may not be correct.
The correct statement is statement B that is the line of best fit will be vertical.
What is a scatter plot ?
A scatter plot is a graph in which the values of two variables are displayed along two axes, and any correlation is revealed by the pattern of the resulting points.
It is given that , after a particular amount of hours of sunlight, Erika made a scatterplot showing the height that a plant increased to. On the horizontal axis, the plant height was shown.
We know that in a scatter plot , the values of two variables are displayed along two axes. As the plant height was shown on the horizontal axis. The other value which is amount of hours of sunlight will be on the vertical axis.
So , the statement which best describes how Erika should draw her line of best fit i.e., the line of best fit will be vertical.
Therefore , the correct statement is statement B that is the line of best fit will be vertical.

Write the equation using the graph In slope-intercept form
Answer:
y=(2/3x)+2
Step-by-step explanation:
Selected Points: (3,4) & (-3,0)
Slope (m) = (y2-y1) / (x2-x1)
m=(4-0) / [3-(-3)]
m=4/(3+3)
m=4/6
m=2/3
Point Slope Form: y-y1=m(x-x1)
y-4=(2/3)(x-3)
y-4=(2/3x)-2

What is an equation of the line that passes through the point (-6,-1) and is perpendicular to the line 6x-y=7
Answer:
y=-1/6x-2
Step-by-step explanation:
Lets find the slope of the given line
6x-7=y,m=6
The slope of the perpendicular line would be=-1/6
Using the point-slope form y-y1=m(x-x1)
y--1=-1/6(x--6)
y+1=-1/6(x+6)
6y+6=-x-6
6y=-x-6-6
6y=-x-12
y=-1/6x-2

Anthony drives 15 km at 40 kph and return at the rate of 60kph , what is the average rate for the entire round trip
9514 1404 393
Answer:
48 kph
Step-by-step explanation:
The distance is immaterial, as long as it is the same at both speeds. The total time for some distance d is ...
t = d/40 +d/60
And the average speed is ...
2d/t = 2d/(d(1/40 +1/60) = 2/(1/40 +1/60) = 2(40)(60)/(40+60) = 4800/100 = 48
The average rate for the round trip is 48 kph.

Additional comment
This value is called the harmonic mean of the two speeds. It is the reciprocal of the average of the reciprocals of the speeds.

suppose that p is the probability that a randomly selected person is left handed. The value (1-p) is the probability that the person is not left-handed. In the sample of 100 people, the function V(p)= 1000 p(1-p) represents the variance of the number of left-handed people in a group of 100.
a) What value of p maximizes the variance?
b) What is the maximum variance?
Answer:
a) 1/2
b) 250
Step-by-step explanation:
The start of the question doesn't matter entirely, although is interesting to read. What we are trying to do is find the value for [tex]p[/tex] such that [tex]1000p(1-p)[/tex] is maximized. Once we have that [tex]p[/tex], we can easily find the answer to part b.
Finding the value that maximizes [tex]1000p(1-p)[/tex] is the same as finding the value that maximizes [tex]p(1-p)[/tex], just on a smaller scale. So, we really want to maximize [tex]p(1-p)[/tex]. To do this, we will do a trick called completing the square.
[tex]p(1-p)=p-p^2=-p^2+p=-(p^2-p)=-(p^2-p+1/4)-(-1/4)=-(p-1/2)^2+1/4[/tex].
Because there is a negative sign in front of the big squared term, combined with the fact that a square is always positive, means we need to find the value of [tex]p[/tex] such that the inner part of the square term is equal to [tex]0[/tex].
[tex]p-1/2=0\\p=1/2[/tex].
So, the answer to part a is [tex]\boxed{1/2}[/tex].
We can then plug [tex]1/2[/tex] into the equation for p to find the answer to part b.
[tex]1000(1/2)(1-1/2)=1000(1/2)(1/2)=1000*1/4=250[/tex].
So, the answer to part b is [tex]\boxed{250}[/tex].
