Step-by-step explanation:
When Camden runs the 400 meter dash, his finishing times are normally distributed with a mean of 65 seconds and a standard deviation of 1.5 seconds. Using the empirical rule, determine the interval of times that represents the middle 68% of his finishing times in the 400 meter race.
Answer:
63.5, 66.5
Step-by-step explanation:
Approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.
What is the empirical rule?The empirical rule states that for a normal distribution, approximately 68% of the data lies within one standard deviation of the mean, approximately 95% of the data lies within two standard deviations of the mean, and approximately 99.7% of the data lies within three standard deviations of the mean.
Since we want to find the interval that represents the middle 68% of Camden's finishing times, we need to find the range of times that are one standard deviation above and below the mean.
The mean of Camden's finishing times is 65 seconds, and the standard deviation is 1.5 seconds, so the interval that represents the middle 68% of his finishing times is:
[65 - 1.5, 65 + 1.5] = [63.5, 66.5] seconds
This means that approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.

Question 5 (1 point) 5 The Cool Shirts company prints personalized designs on T-shirts. The cost y for x shirts with the same design is shown in the table below. y 10 $105 20 $185 30 $265 4:0 $345 Which equation represents the relationship between x and yo! A y = 10x - 55 By = 80x + 105 C y = 8x + 25 D y = 25x + 8 a А B od
Answer:
y = 8x + 25
Step-by-step explanation:
Using the coordinates (10, 105) and (20, 185)
The standard linear equation is expressed as y = mx+c
m is the slope
c is the intercept
m = 185 - 105/20-10
m = 80/10
m = 8
Get the y-intercept
Since y = mx+c
105 = 8(10) + c
105 = 80 + c
c = 105 - 80
c = 25
Get the required equation
Recall that y = mx+c
y = 8x + 25
Hence the required equation is y = 8x + 25

Answer:
x = 1, y = 3
Step-by-step explanation:
Given:
x - y = -2
2x + y = 5
First, add y on both sides for the first equation.
x = y - 2
Then, plug in x into the second equation.
2(y -2) + y = 5
2y - 4 + y = 5
3y = 9
y = 3.
Next, now that you've found y, plug it into either the first or second equation to solve for x. I'll be using the second equation.
2x + 3 = 5
2x = 2
x = 1.
Ans: x = 1, y = 3

Work out the size of angle x.
105
140
Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
x + (180 - 105) + (180 -140) = 180
x + 75 + 40 = 180
x = 180 -75 - 40
x = 65

Answer:
G = (-5,-5)
Step-by-step explanation:
d = sqrt (x^2 - x^1)^2 + (y^2 - y^1)^2
Let's use the coordinate pairs: (6,4) and (6,-5).
Input.
d = sqrt (6 - 6)^2 + (-5 - 4)^2
Solve.
d = sqrt 0 + (-9)^2
d = sqrt 0 + 81
d = sqrt 81
d = 9
Count 9 places back from (6, -5) , then you will arrive at (-5,-5).
Thus, the fourth vertex of the rectangle "EFGH" is (-5,-5) for G.

Answer:
mean = 2
median = 2.5
Step-by-step explanation:
There are a total of 20 goals (1*0 + 3*1 + 1*2 + 3*5 = 0 + 3 + 2 + 15 = 20)
There are 10 games, so 20/10 = 2 = mean
Threre are 5 games with goals greater than 2.5 and 5 games with goals below 2.5. So the median is 2.5

All lines are congruent to one another.
Answer:
This is false. Lines will be congruent if they have the same length, which is not the case in all situations.
Answer:
Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.
