Step-by-step explanation:
[tex]22x = 23 \\ \frac{22x}{22} = \frac{23}{22} \\ x = \frac{23}{22} [/tex]
Answer:
x = 23/22 = 1.045
Step-by-step explanation:
Solving a Single Variable Equation :
1.1 Solve : 22x-23 = 0
Add 23 to both sides of the equation :
22x = 23
Divide both sides of the equation by 22:
x = 23/22 = 1.045

When Landon runs the 400 meter dash, his finishing times are normally distributed with a mean of 60 seconds and a standard deviation of 1 second . If Landon were to 38 practice trials of the 400 meter dash , how many of those trials would be faster than 58 seconds , to the nearest whole number ?
Answer:
87% would be faster than 58 seconds
Step-by-step explanation:
Landon runs the 400 meter dash, his finishing times are normally distributed with a mean of 60 seconds and a standard deviation of 1 second
[tex]\mu = 60[/tex]
Standard deviation =[tex]\sigma = 1[/tex]
We are supposed to find Landon were to 38 practice trials of the 400 meter dash , how many of those trials would be faster than 58 seconds , to the nearest whole number i.eP(x<58)
[tex]Z=\frac{x-\mu}{\sigma}\\Z=\frac{58-60}{1}\\Z=-2[/tex]
Refer the z table for p value
P(x<58)=0.0228
Landon were to 38 practice trials
So, P(x<58)=[tex]38 \times 0.0228=0.8664[/tex]
So, 86.64% would be faster than 58 seconds
Hence 87% would be faster than 58 seconds

What is the area of a rectangle with vertices at (7,3), (12,3), (12, 11), and (7,
11)?
O A. 26 units
O B. 40 units2
O c. 45 units2
O D. 20 units2
Answer: 40 units
Step-by-step explanation:
(7,3) (12,3) on the same y coordinate, 5 squares apart
(12,3) (12,11) on the same x coordinate, 8 squares apart
8 × 5 = 40
The area of a rectangle with vertices at (7,3), (12,3), (12, 11), and (7,11) is 40 square unit.
What are Coordinates?A brace of figures called equals are used to detect a point or a form in a two- dimensional aeroplane . Thex-coordinate and the y- match are two figures that define a point's position on a 2D aeroplane .
We have vertices of rectangle as
vertices at (7,3), (12,3), (12, 11), and (7, 11).
Now, the coordinates (7,3) and (12,3) have the same y coordinate also the difference in x match is 5 places piecemeal.
and, (12,3) and (12,11) have the same x coordinate then the difference in y coordinate is 8 squares apart.
So, the Area of rectangle
= 8 × 5
= 40 square unit

The literary device known as repetition is used to emphasize the same concept or idea or to communicate a particular message by repeatedly using it.
What is repetition?Although repetition typically relates to sentences or words, it can also be present in the sounds that words make. There are three different techniques to show repeat with noise. Consonance, harmony, starting, and alliteration are the names of these three literary devices.
The term "as usual" is repeated in this situation to emphasize how nothing exceptional was going on; it was just the block bash as usual. The predictability demonstrates that everyone's attitudes and behaviors were uniform and fairly predictable. That is wanted to predict the neighborhood and how they act in a certain way

Let the equation C = 2.32 N + 34,180 represent the cost of raising a child, C, on an income, N.
If the Murphy family has an annual income of $60,000, what is the expected cost of raising a child?
$172,460
$173,380
$175,620
$176,980
Answer:
173,380
Step-by-step explanation:
just took the test and got it right
The expected cost of raising a child is $173,380.
Given,
C = 2.32 N + 34,180.
C represents the cost of raising a child.
N represents the income.
If the Murphy family has an annual income of $60,000.
We are to find the expected cost of raising a child using the given equation.
We have,
C = 2.32 N + 34,180________(A)
Now,
If the Murphy family has an annual income of $60,000.
N = $60,000___________(B)
Putting (B) in (A).
C = 2.32 x $60,000 + 34,180
C = 139,200 + 34,180
C = $173,380.
Thus the expected cost of raising a child is $173,380.

Evaluate 12 − 6 + (14 − 8)2 = ____________. (1 point)
Answer:
18
Step-by-step explanation:
you do PEMDAS
there is parenthesis
12-6+6 times 2
there is multiplication
12-6+12
then there is subtraction and addition so you have to do it left to right
18
Answer:
18
Step-by-step explanation:
When solving these types of questions, you want to remember PEMDAS. According to PEMDAS, P is parenthesis. (14-8) is in parenthesis. 14-8 is 6.
Now the equation looks like this:
12-6 + (6)2
There are no Exponents in this equation, but there is multiplication. If there are no operations between two integers, that means it is likely to be multiplication. 6 x 2 is 12.
Now the equation looks like this:
12-6+ 12
Even though, according to PEMDAS, Addition is before subtraction, you can do either one from left to right. Even with multplication and division.
Now the equation looks like this:
6+12
Obviously 6+12 is 18. So, 18 is the answer.
A basket contains seven apples and four peaches. You randomly select a piece of fruit and then return it to the basket. Then you randomly select another piece of fruit. Both pieces of fruit are apples

Total fruits = 7+ 4 = 11
Probability of apples = 7/ 11
The probability of the apples should be [tex]7\div 11[/tex]
Calculation of the probability:Since A basket contains seven apples and four peaches. You randomly select a piece of fruit and then return it to the basket.
So here the total fruits should be
= 7 + 4
= 11

Step-by-step explanation:
It's a reflection of it's self, so the only reasonable answer would be the the letter of the copied image of itself.
Think about it like a mirror. One side is what you see, but what is facing it is the original, so if the original is C then its copy is G.
Which graph shows a rate of change of one-half between –4 and 0 on the x-axis? On a coordinate plane, a straight line with a positive slope crosses the x-axis at (6, 0) and the y-axis at (0, 3). Solid circles appear on the line at (negative 4, negative 1), (0, 3). On a coordinate plane, a parabola opens up. It goes through (negative 5.25, 4), has a vertex of (0, negative 3), and goes through (5.25, 4). Solid circles appear on the parabola at (negative 4, 1), (0, negative 3). On a coordinate plane, a parabola opens down. It goes through (negative 5.5, negative 4), has a vertex of (0, 4), and goes through (5.5, negative 4). Solid circles appear on the parabola at (negative 4, 0), (0, 4). On a coordinate plane, a curved line opens up and left in quadrant 2. It is asymptotic to the negative x-axis and positive y-axis. Solid circles appear on the line at (negative 4, 0.25), (0, 4).
Answer:
First option
Step-by-step explanation:
There is a mistake in the description of the first function.
On a coordinate plane, a straight line with a positive slope crosses the x-axis at (-6, 0) and the y-axis at (0, 3). Solid circles appear on the line at (-4, 1), (0, 3).
Given two points of a function, (x1, y1) and (x2, y2), its rate of change between them is:
Rate of change: (y2 - y1)/(x2 - x1)
Points of the 1st graph: (-4, 1), (0, 3).
Rate of change: (3- 1)/(0 - (-4)) = 1/2
Points of the 2nd graph: (-4, 1), (0, -3).
Rate of change: (-3 - 1)/(0 - (-4)) = -1
Points of the 3rd graph: (-4, 0), (0, 4).
Rate of change: (4 - 0)/(0 - (-4)) = 1
Points of the 4th graph: (-4, 0.25), (0, 4).
Rate of change: (4 - 0.25)/(0 - (-4)) = 0.9375
