In a normal distribution, 95% of the data fall within how many standard
deviations of the mean?
O A. Two standard deviations
O B. One standard deviation
C. It cannot be determined from the given information.
O D. Three standard deviations
In a normal distribution, 95% of the data falls within two standard deviations.
What is a normal distribution?
The most typical distribution function for independent, randomly produced data is the normal distribution, commonly known as the Gaussian distribution. Every statistical report uses this well-known bell-shaped curve, from survey analysis and quality control to resource allocation.
Here,
We have to determine in a normal distribution, 95% of the data fall within how many standard deviations of the mean.
We concluded that 95% of the data points will fall within two standard deviations of the mean. 99.7% of the data points will fall within three standard deviations of the mean.
Hence, In a normal distribution, 95% of the data falls within two standard deviations.

Jessie is going to the county fair. The cost of admission is $5.00 and it is $2.00 for each ride. If Jessie has $19.00, Write an equation to determine how many rides Jessie can ride. Draw and use algebra tiles to solve.
By direct calculation, we will see that Jessie can go to 7 rides in the county fair.
So we know that the cost of admission is $5.00 and each ride costs $2.00.
So if you go to the county fair and go to x rides, the cost is:
c(x) = $2.00*x + $5.00
And you have $19, then by solving:
c(x) = $19
We can find the number of rides at which Jessie can go.
$19 = $2.00*x + $5.00
$19 - $5 = $2*x
$14 = $2*x
$14/$2 = x = 7
Jessie can go to 7 rides.

Answer: -15
Step-by-step explanation:
The average rate of change for the interval from x = 7 to x = 8 is -15. The correct option is B.
What is quadratic function?A quadratic polynomial in mathematics is a polynomial of degree two in one or more variables. The polynomial function defined by a quadratic polynomial is known as a quadratic function.
Since the quadratic function has a vertex at (0,3), the equation for the function can be written in vertex form as:
y = a(x - 0)^2 + 3
Where "a" is a constant that determines the shape of the parabola. To find the value of "a", we can use one of the other points on the parabola. Let's use the point (1, 2):
2 = a(1 - 0)^2 + 3
Simplifying this equation, we get:
a = -1
So the equation for the quadratic function is:
y = -x^2 + 3
Now we can use this equation to find the average rate of change between x = 7 and x = 8. The value of the function at x = 7 is:
y = -7^2 + 3 = -46
The value of the function at x = 8 is:
y = -8^2 + 3 = -61
The average rate of change between x = 7 and x = 8 is:
(y2 - y1) / (x2 - x1) = (-61 - (-46)) / (8 - 7) = -15
Therefore, the average rate of change for the interval from x = 7 to x = 8 is -15.

Find the distance between the two points. (2,7) and (−18,22)
Answer:
d = 25
Step-by-step explanation:
d = sqrt( (y2 - y1)^2 + (x2 - x1)^2 )
d = sqrt( (7 - 22)^2 + (2 - (-18) )^2 )
d = sqrt ( (- 15)^2 + 20^2 )
d = sqrt ( (225) + (400) )
d = sqrt (625)
d = 25

The residual for a predicted relative abundance when the rainfall was 3 inches is 1.25. What is the actual relative abundance when the rainfall was 3 inches
Answer:
The actual relative abundance will be "7.59".
Step-by-step explanation:
The residual on something like a curve anywhere at a point becomes expressed as the maximum at either the position between some of the real y-value as well as the expected y-value. Consequently, the difference regarding true relative abundance as well as expected relative abundance seems to be 1.25 whether we presume that the x-variable represents rainfall, as well as they-variable, represents the relative abundance of locusts.The predicted relative abundance for 3 inches rainfall will be:
= [tex]6.7 - (0.12\times 3)[/tex]
= [tex]6.34[/tex]
The residual will be:
= [tex]actual - predicted \ relative \ abundance[/tex]
= [tex]1.25[/tex]
Now,
The actual relative abundance will be:
= [tex]1.25 + predicted \ relative \ abundance[/tex]
= [tex]1.25 + 6.34[/tex]
= [tex]7.59[/tex]
Remember that perhaps the residual positive value means that even the calculation underestimates the relative abundance. The real relative abundance, however, is 7.59.
which is the equation of a line in point slope form that passes through the point 2,5 and has a slope of 1/2
Answer:
see below
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - 2 = 4(x- -1)
y - 2 = 4(x+1)
slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 4x+b
Substituting the point in
2 = 4(-1)+b
2 = -4+b
6 =b
y = 4x+6
standard form
Ax +by = c where A is a positive integer and b and c are integers
y = 4x+6
Subtract 4x from each side
-4x+y = 6
Multiply by -1
4x -y = 6

I’d ABCD is dilated by a scale factor of 2 about point E, which of the following is true about line segment E’F’
Answer:
Line Segment EF passes through the center of the dilatation
Step-by-step explanation:
I just know...
Option (4) will be the correct option.
Given in the question,
ABCD is dilated by a scale factor of 2 about point E.A'B'C'D' is the dilated figure.Option (1). E'F' is perpendicular to EF.
Since, center of dilation of ABCD is at E, E' will coincide point E.
Therefore, EF and E'F' can't be perpendicular.
Option (2). E'F' is parallel to EF.
Since, center of dilation of ABCD is at E, point E' will coincide point E.
Therefore, E'F' can't be parallel.
Option (3). E'F' intersects with point B'.
Since, center of dilation of ABCD is at E, EF will lie on E'F'.
Therefore, E'F' cant intersect point B'.
Option (4). E'F' passes through center of dilation.
Since, center of dilation of ABCD is at E, therefore, E'F' will pass through the center of dilation E.
Therefore, Option (4) is the correct option.
