On a standardized exam, the scores are normally distributed with a mean of 250 and
a standard deviation of 50. Find the 2-score of a person who scored 375 on the exam.
Answer:
the z-score is within 3
Step-by-step explanation:
first you got to take the standard deviation and add it to the mean since 375 is greater than 250. so the equastion would be
250+50=300+50=350+50=40
so the z-score for the value of 375 is within 3
Answer: 2
Step-by-step explanation:
z=\frac{x-\mu}{\sigma}
z=
σ
x−μ
z-score formula
z=\frac{300-250}{25}
z=
25
300−250
Plug in values
z=\frac{50}{25}
z=
25
50
Subtract
z=2
z=2
Divide
\text{They scored 2 standard deviations above the mean.}
They scored 2 standard deviations above the mean.

Solve: 2x - 3y = 9 and x + 2y = 1
Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 9 → (1)
x + 2y = 1 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = 1 - 2y → (3)
Substitute x = 1 - 2y into (1)
2(1 - 2y) - 3y = 9
2 - 4y - 3y = 9
- 7y + 2 = 9 ( subtract 2 from both sides )
- 7y = 7 ( divide both sides by - 7 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = 1 - 2(- 1) = 1 + 2 = 3
solution is (3, - 1 )

What are the coordinates of the midpoint of diagonal LN?
Answer:
4. (-2 1/2, 4 1/2)
Step-by-step explanation:
Midpoint Formula is (x1+x2)/2, (y1+y2)/2
So (-6+1)/2 , (1+8)/2 = (5)/2, (9)/2 = (2.5,4.5)
And that in fraction form is (-2 1/2, 4 1/2)
If x and x+ 10 are a pair of adjacent angle find them
Answer:
85° and 95°
Step-by-step explanation:
Given that , x and x + 10 are a pair of angles .
If they will be pair of angles on the same line , then their sum will be 180° .=> x + x + 10° = 180°
=> 2x = 180° -10°
=> 2x = 170°
=> x = 170°/2
=> x = 85° .
Hence the two angles are 85° and 95° .Which of the following shows the inverse of {(2, 5), (9, -1), (4, 0), (-3, 8)}? Group of answer choices

Can someone plz help me on this I’m bad at doing these plz I bed u I beg u plz
Answer:
I'm sorry me dont know kfnkdks
Answer:
A
Step-by-step explanation:
Area of the rectangle
A = base x width = 8 x 6 = 48 cm^2
Area of the triangle
A = (base x height)/2 = (6 x 4)/2 = 12 cm^2
two semicircles are equal to a circle
radius = diameter / 2 = 3/2 = 1.5 cm
A = radius^2 x pi = 1.5^2 x pi = 7 cm^2 (round to the nearest whole number)
total area
48 + 12 + 7 = 67 cm^2
What are five steps for solving percentage problems?
Answer:
Find the percentage of the original or real number.
Multiply the final number by 100.
Divide the result of the multiplication by the percentage.
Have a great day
The proportion of the original or true number is then added 100 to the final figure.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
Let's suppose it is required to find the x percentage of y:
First step:
= x% of y
Second step:
= (x/100)y
Third step: Divide x by 100
= 0.01xy
Fourth step: Multiply the remaining term(0.01x and y).
= 0.01xy
The fifth step: Round off if required
= 0.01xy %
Calculate the proportion of the original or true number.
Add 100 to the final figure.
Subtract the percentage from the multiplication result.
Thus, the proportion of the original or true number is then added 100 to the final figure.

What is the interquartile range (IQR) of the data set represented by this box plot?
Answer:
The IQR (interquartile range) of the data set represented by this box plot is 22 units.
Step-by-step explanation:
Each number of the data set represented as a box plot is something the numbers have individually. The lowest number there (the first number), 38, is called the minimum. The highest number there (the last number), 75, is called the maximum. The second number there, 45, is called the lower quartile. The third number there, 50, is called the median or middle quartile. The fourth number there, 67, is called the higher quartile. In order to find the interquartile range, you need to find the difference between the lower quartile and higher quartile, which means to subtract.
67 (highest quartile) - 45 (lower quartile) = 22 (interquartile range)
Therefore, the IQR (interquartile range) of the data set represented by this box plot is 22 units.
Answer:
It’s 22

What is the lenghth of a baseball cap 30 kilometers or 30 meters or 30 millimeters or 30 centimeters
Answer:
30 centimeters
Step-by-step explanation:
1. 30 kilometers is way too large for a baseball cap to be measured in. Kilometers are usually used to measure distances between cities.
2. 30 meters is also too large for a baseball cap to be measured in. 30 meters are about 15 basketball players stacked on top of one another.
3. Last and remaining choice is 30 cm. 30 cm is about the same length as a 12 inch ruler.
