A normally distributed set of data has been generated where 50% of the data lies below 97 and 70% lies below 104. Determine the mean and standard deviation of this data.
Answer:
i dont understand either
Step-by-step explanation:
A normally distributed set of data has been generated where 50% of the data lies below 97 and 70% lies below 104. Then, mean of the data is equal to 97 and standard deviation is equal to 13.358.
What is normal distribution?Normal distribution is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
Given that 50% of the data lies below 97, implies that median of the data is equal to 97. In a normal distribution, mean = median = mode, therefore, mean = 97.
Given the mean and value at 70th percentile, we can find the standard deviation.
Using the z score - percentile table, we find that the z score corresponding to the given percentile.
z score corresponding to 70th percentile = 0.524
[tex]0.524 = \frac{x - mean}{standard\ deviation}\\ \\0.524 = \frac{104 - 97}{standard\ deviation} \\\\standard\ deviation = \frac{7}{0.524} = 13.359[/tex]

Complete the slope-intercept form of this line.
y = –4x +
Answer:
the slope intercept form of this line is y = -4x + 9.
Step-by-step explanation:
The equation of line is given by:
y = mx + b .....[1]
where,
m is the slope of line
b is the y-intercept.
As per the statement:
Given: The rate of change = -4
Substitute in [1] we have;
y = -4x + b
Substitute the values of any (x, y) from the given table.
Let x = -1 and y = 13
then;
13 = -4(1-)+b
⇒13 = 4+b
Subtract 4 from both sides we have;
9 = b
or
b = 9
⇒the equation become, y = -4x+9
Therefore, the slope-intercept form of this line is, y = -4x+9

What is the circumference?The Circumference (or) perimeter of circle = 2πR. where, R is the radius of the circle.
Given
A circular swimming pool has a radius of 15 ft.
There is a path all the way around that pool that is three feet wide.
A circle has a radius of 15 feet.
A larger circle goes around the smaller circle that is 3 feet wide.
The radius of the outer edge of the path around the pool = Radius of circle + width of outer circle.

The triangle below has a perimeter of 51. Solve for x.
Answer:
x = 6
Step-by-step explanation:
The perimeter is the sum of the 3 sides of the triangle. Sum the 3 sides and equate to 51, that is
15 + 5x - 6 + 2x = 51
7x + 9 = 51 ( subtract 9 from both sides )
7x = 42 ( divide both sides by 7 )

Find the coordinate of W' after a 270 counterclockwise rotation of the triangle about the origin and then a translation of 2 units down and 1 unit to the right.
Answer: d: -2,2
Step-by-step explanation:
The coordinates of W' after the rotation and the translation is (-2, 2).
Option D is the correct answer.
We have,
The rule for a rotation by 270° about the origin.
(x, y) → (y, −x)
Now,
W = (-4, -3)
Applying the rule.
W = (-3, 4)
Now,
A translation of 2 units down and 1 unit to the right.
So,
W = (-3, 4)
W = (-3 + 1, 4 - 2)
W = (-2, 2)
Thus,
The coordinates of W' after the rotation and the translation is (-2, 2).

Select the tables that show a proportional relationship between x and y.
Table 2 depicts the proportional relationship between x and y as 2/5 = 4/10 = 6/15.
What is meant by proportional relationship?A proportional relationship exists when each pair of data values is related in the same way, by multiplying by a factor. A proportional relationship can be identified by looking at data, an equation, or a graph. Calculating the ratio of each pair of values can tell you if a table has a proportional relationship. If all of those ratios are the same, the table indicates a proportional relationship. Now consider an example of a proportional relationship in our daily lives: When we fill up our car with gas, there is a connection between the number of gallons of fuel we put in the tank and the amount of money we will have to pay.Therefore,
1x / y
Simplifying the equation, then we get,
1/4 = 2 /8 = 3 / 12 = 6 / 24
= 2 / 8
y l x
Put the value of x and y in above equation,
4/1 = 8 /2 = 12/3

5/2 = 10 /4

Suppose a certain cell reproduces itself in four hours. If a lab researcher begins with 50 cells, how many cells will there be after one day, two days, and three days? (Hint: Use the exponential function y = 50(2x). )
By working with the exponential function, we will see that:
After 1 day there are 3,200 cells.After 2 days there are 204,800 cells.After 3 days there are 13,107,200 cells.How to find the population of the cell?We know that the population of the cell doubles every four hours, then we can write:
y = 50*(2)^x
Where x is time in lapses of 4 hours, and 50 is the initial population of the cell.
In one day, there are 6 groups of 4 hours, then after one day we have:
y = 50*(2)^6 = 3,200 cells.In two days, there are 12 groups of 4 hours, then after two days we have:
y = 50*(2)^12 = 204,800 cells.In 3 days, there are 18 groups of 4 hours, then after 3 days there are:

Raj correctly determined that ray LH is the bisector of AngleGLI. A line contains points K, L, M. 4 lines extend from point L. One line extends to point F, another to G, another to H, and another to I. Which information could he have used to determine this? AngleGLH Is-congruent-to AngleILM mAngleKLM = 5mAngleILM , mAngleGLI = 2mAngleGLH, mAngleGLI = mAngleGLH + mAngleHLI
answer : mAngleGLI = 2mAngleGLH
Step-by-step explanation:
The information that could have used to determine this information is
mAngleGLI = 2mAngleGLH
from the figure, we can see that
mAngleGLI = mangleGLH + mangleHLI
Hence we can conclude mangleGLH = mangleHLI
therefore the ray LH bisects angleGLI into two equal angles GLH & HLI.
Answer: mGLI = 2mGLH
