solve the inequality
The heights of male seniors in high school closely follow a normal distribution N(µ,σ) = N(70.5,2.6) , where the units are inches. a) If we randomly sample the heights of five male seniors, what distribution should the sample mean follow? Give your answers to two decimal places.
The sample will also be normally distributed, with same mean as the population, so µ = 70.5, but the standard deviation would be divided by the square root of the sample size, so σ = 2.6/√5 ≈ 1.16.
N(70.5, 1.16)
The sample will also be normally distributed, with the same mean as the population(µ = 70.5) and the standard deviation of 1.16 inches.
What is a normal distribution?A normal distribution is a probability distribution that is used to represent events with a default behaviour and accumulated potential departures from it.
As it is given that the heights of male seniors in high school closely follow a normal distribution N(µ,σ) = N(70.5,2.6), where the units are inches.
Therefore, the mean will be the same (µ = 70.5), but the standard deviation for the sample size of the heights of five male seniors, can be written as,
[tex]s=\dfrac{\sigma}{\sqrt n} = \dfrac{2.6}{\sqrt5} = 1.16[/tex]
Hence, The sample will also be normally distributed, with the same mean as the population(µ = 70.5) and the standard deviation of 1.16 inches.

What would the answer be image below
Answer:
The points would be: (-3, 3) (-4, -1) (2, -1) (1, 3)
Step-by-step explanation:
Because when you move 4 units left, all of the x values in the points will go down by 4, and when you move 2 units down, the y values will go down by 2 units. So when applied to the points shown, you get the answer I put.
I believe this is correct? Hope it helps!
Write the equation of the line that passes through the points (3,19) and (-2,-16)
Answer:
y = 7x - 2
Step-by-step explanation:
y2 - y1 / x2 - x1
-16 - 19 / -2 - 3
-35/-5
= 7
y = 7x + b
19 = 7(3) + b
19 = 21 + b

When you have a lot of the same kind of problem to solve, it makes a certain amount of sense to let a spreadsheet do it. You can enter the formulas once, and then all you need to do is supply the different data for the different problems.
Here, we can put the equations into standard form, then use Cramer's Rule to solve them. For the two equations ...
ax +by = cdx +ey = gwe can define ...
D = (ae -db)
Then the values of x and y are ...
x = (ce -gb)/D
y = (ag -dc)/D
The attached spreadsheet implements these equations to find the values of x and y.
__
The second equation of the 2nd Question is not given in standard form. To put it into standard form, we need to subtract 4y from both sides:
x -4y = -5

Additional comment
Many graphing calculators have matrix functions that will solve sets of linear equations, too. For those, you can use the function that puts the coefficient matrix into Reduced Row-Echelon Form. Often that function is named RREF( ), as it is on my TI-84 and HP-48 calculators. The input coefficient matrix will look like ...
[tex]\left[\begin{array}{ccc}a&b&c\\d&e&g\end{array}\right][/tex]
and the output matrix will look like ...
[tex]\left[\begin{array}{ccc}1&0&\text{x-value}\\0&1&\text{y-value}\end{array}\right][/tex]
Effectively, the equations are solved by "elimination." If the calculator shows [0 0 0] in the bottom row of output, it means the equations are dependent and there are infinite solutions. If it shows [0 0 1], the equations are inconsistent, and there are no solutions.

What is the slope y, equals, x, plus, 5?
Answer:
slope = m = 1
Step-by-step explanation:
y = x + 5
slope intercept form is y = mx + b, where m is the slope.
in this case, the m = 1; therefore, the slope is 1

Find the measures of angles q, r, and s.
(PLEASE help ASAP I will give brainliest!)
Answer:
q= 100
r= 135
s= 125
Step-by-step explanation:
These are the angles
The measures of angles q, r, and s are q = 100°, r = 135°, and s = 125°.
What are Alternate Interior Angles?Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. These angles are always equal.
These are the angles
⇒ q = 180 - 80 = 100
⇒ r = 180 - 45= 135
⇒ s = 180 - (180 - 80 - 45) = 125
So the sum of the measures of angles q, r, and s
⇒ q + r + s = 100 + 135 + 125 = 360°
Thus, the measures of angles q, r, and s are q = 100°, r = 135°, and s = 125°.

The data set below shows a city's high temperature for 11 days, in degrees Fahrenheit.
56, 60, 60, 60, 62, 64, 64, 66, 66, 90, 95
Which is the most reasonable measure of central tendency for the data set?
mean
mode
range
median
Answer:
I think its range I dont know
Step-by-step explanation:
The mean is the maximum often used as a degree of critical tendency because it makes use of all values inside the information set to give you an average. For statistics from skewed distributions, the median is higher than the implied because it isn't motivated through extremely big values.
The correct option is A.
Which is a better measure of center mean or median?The median is normally a better degree than the middle whilst there are intense values or outliers because it isn't always stricken by the right numerical values of the outliers. The suggestion is the maximum common measure of the middle. The phrases “mean” and “common” are regularly used interchangeably.

which expression is equivalent to the given polynomial expression? (9mn-19m^4n)-(8m^2+12m^4n+9mn)
A. -31m^4n+18mn-8m^2
B. -7m^4n+8m^2
C. -7m^4n+18mn-8m^2
D. -31m^4n-8m^2
9514 1404 393
Answer:
D. -31m^4n-8m^2
Step-by-step explanation:
Eliminate parentheses by distributing the minus sign. Then collect terms:
(9mn-19m^4n)-(8m^2+12m^4n+9mn) = 9mn -19m^4n -8m^2 -12m^4n -9mn
= m^4n(-19 -12) +mn(9 -9) +m^2(-8)
= -31m^4n -8m^2 . . . . . matches choice D
-5 (-4p-3)>-105
can i get some help on that?
Answer:
p>-6
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
20p+15>−105
Step 2: Subtract 15 from both sides.
20p+15−15>−105−15
20p>−120
Step 3: Divide both sides by 20.
20p/20 > -120/20
p>-6
Answer:
p > -6
Step-by-step explanation:
-5(-4p-3) > -105
First, multiply out the left side to get:
20p+15 > -105
Then take fifteen away from both sides to get:
20p > -120
Then divide both sides by twenty to get:
p > -6
