Step-by-step explanation:
8x =22
Divide by 8
X=11/4
The required improper fraction is 11/4.
What is an improper fraction?Improper fractions are defined as fractions for which the numerator is greater than the denominator.
Given that an equation, 8x = 22, we need to find the value of x,
8x = 22
Diving both the sides by 8, we get,
x = 22/8
x = 11/4
Here, the numerator is greater than the denominator.
Hence, the required improper fraction is 11/4.

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:
y = 50*(2)^18 = 13,107,200 cells.If you want to learn more about exponential functions, you can read:

a line through (2, 1) meets the curve x²-2x-y=3 at A(-2,5) and at B. FIND THE COORDINATES OF B
Answer:
(3,0)
Step-by-step explanation:
We know the line will Pss through
(-2,5) and (2,1) so
let find the slope
[tex] \frac{1 - 5}{2 - ( - 2)} = \frac{ - 4}{4} = - 1[/tex]
So the slope is -1.
We know it passes through 2,1 so use point slope to find b.
[tex]y - 1 = - 1(x - 2)[/tex]
[tex]y - 1 = - x + 2[/tex]
[tex]y = - x + 3[/tex]
Set that equal to
[tex] {x}^{2} - 2x - y = 3[/tex]
[tex] {x}^{2} - 2x - 3 = y[/tex]
[tex] {x}^{2} - 2x - 3 = - x + 3[/tex]
[tex] {x}^{2} - x - 6 = 0[/tex]

[tex]x = 3[/tex]
Point (3,0).
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 )

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]

The Bandits baseball team played 75 games and won 55 of them. What percent of the games did they lose? (Round your answer to the nearest hundreth - 2 decimal places.)
Answer:
26.6%
Step-by-step explanation:
total = 75 games
number of games won = 55
number of games lost = 75 - 55 = 20
75 — 100%
20 — x%
x = 20/75 * 100 = 26.6%
Answer:73.33%
Step-by-step explanation: If you do 55/75 you will get 0.73 repeating and you would move the decimal place 2 places to the right.
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

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

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

Mikki created a painting with an area of 32 square feet and a length of 4 feet. They create a second painting with an area of 24 square feet. It has the same width as the first painting. what is the length of the second painting?
Answer:
3 feet
Step-by-step explanation:
To begin, find the width of the first painting by dividing 32 by 4. You get 8 feet as the width. Since the second painting has a width of 8, divide 24 by 8 to get the length (area of a rectangle is length times width). You get that the length of the second painting is 3 feet.
