Answer:
26
Step-by-step explanation:
Subtract the mean (84) from each of the four scores, obtaining
2, -3, 3, - 2
These are the "deviations."
Next, square each of these four deviations, obtaining
(2)^2 = 4, and:
(-3)^2 = 9, and:
(3)^2 = 9, and:
(-2)^2 = 4
Then the sum of the squared deviations of the scores from the mean is 26.

Using the digits 0-9, at most one time each, create five ordered pair that represent a linear
function that has a greater rate of change than the following (explain how u got that answer)
Answer:
(-9, 0), (-8, 1), (-7, 2), (-6, 3) and (-5, 4)
Step-by-step explanation:
From the graph attached,
Ordered pairs which lie on the given line (-9, 0), (0, 3), (3, 4), (6, 5) and (9, 6).
Since all the points lie on the same line, rate of change of the linear function will be defined by the slope of the given line.
Slope of the line passing through (0, 3) and (3, 4) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{4-3}{3-0}[/tex]
[tex]m_1[/tex] = [tex]\frac{1}{3}[/tex]
Now we have to find the ordered pairs which represent a linear function having slope greater than [tex]\frac{1}{3}[/tex].
So the points will be (-9, 0), (-8, 1), (-7, 2), (-6, 3) and (-5, 4).
Slope of the linear function passing through (-9, 0) and (-8, 1)
[tex]m_2[/tex] = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{1-0}{-8+9}[/tex]
= 1
Here [tex]m_2>m_1[/tex]

6|2x+3|=36 need a mini step by step
Answer:
x=1.5
Step-by-step explanation:
We are trying to get x by itself to see what it equals.
6(2x+3)=36
So first you want to distribute you proprieties. You do that by multiplying 6 and 2x. Then multiplying 6 and 3.
12x+18=36
Now in equations where you need to find the variable, whatever you do on one side of the equal sign, you have to do on the other side. So now we want to subtract 18 from both sides.
12x+18=36
-18 -18
Then we divide 12 from both sides.
12x=18
÷12 ÷12
Now you have your answer!
x=1.5
Find the lowest number divisible by 15, 20 & 25.
Answer:
300.
Step-by-step explanation:
This is the LCM.
15 = 3 * 5
20 = 2 * 2 * 5
25 = 5 * 5
One 5 appears in all 3 factors so we only use this once in the calculation:
LCM = 2 * 2 * 3 * 5* 5 = 300

What is the slope of the line that passes through (4, 5) and (8, -1)?
Answer:
m = -3/2
Step-by-step explanation:
The slope of a line is equivalent to the formula:
m = slope = rise/run = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Given the two coordinate pairs, we can label them accordingly.
In math, coordinate pairs are set up in a way that the x-coordinate is given first and the y-coordinate is given second.
Therefore, with this information, we can label the coordinate pairs with this info.
[tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] is the default labeling system for two coordinate pairs.
Then, we can use this information to label our coordinate pairs, place them into the slope formula, and solve for m.
[tex]m=\frac{-1-5}{8-4}\\\\m = \frac{-6}{4}\\\\\boxed{m=-\frac{3}{2}}[/tex]
is √13 greater or less than 3.5
Answer:yes it is greater
Step-by-step explanation:
Step-by-step explanation:
Hey, there!!
[tex] \sqrt{13 \: } \: is \: not \: greator \: than \: 3.5[/tex]
Because, root 13 means 3.60 also,
So, when you see 3.5 and 3.6 then it's obvious that 3.6 is greator.
Or if you see it in fractional form.
it will be,
18/5 and 7/2.
when we take a like term,
18×2/10 and 7×5/10
They will be ,
36/10 and 35/10.
Which implies 36/10>35/10.
So, the answer is root 13 is not greator than 3.5.
Hope it helps....

20 POINTS: If tan= 3/4, find the CSC I don't know the relationship between tan and csc, please explain your answer
Answer:
[tex]\csc(x)=5/3[/tex]
Step-by-step explanation:
So we know that:
[tex]\tan(x)=3/4[/tex]
Recall that tangent represents the side opposite over the side adjacent.
This means that the opposite side is 3 while the adjacent side is 4.
Therefore, by using the Pythagorean Theorem, we can solve for the third side, which is the hypotenuse:
[tex]a^2+b^2=c^2[/tex]
Substitute a for 3 and b for 4. Thus:
[tex]3^2+4^2=c^2[/tex]
Square and add:
[tex]9+16=c^2\\25=c^2[/tex]
Square root:
[tex]c=5[/tex]
Now, recall that cosecant is the reciprocal of sine. So, find sine first.
Sine is opposite over hypotenuse. From tangent, the opposite is 3 and the hypotenuse as we now know is 5. Thus:
[tex]\sin(x)=3/5[/tex]
And cosecant is the reciprocal of that. Thus:
[tex]\csc(x)=5/3[/tex]
And that's our answer :)
Find the value of n and YZ if Y is between X and Z.
XY = 5n, YZ = 2n, XZ = 91
The value of n and YZ are 13 and 26 respectively
If Y is between X and Z, then:
XY + YZ = XZ
Given the following
XY = 5n
YZ = 2n
XZ = 91
Substitute the given expressions into the formula as shown:
5n + 2n = 91
7n = 91
Divide both sides by 7
7n/7 = 91/7
n = 13
Get the measure of segment YZ
YZ = 2n
YZ = 2(13)
YZ = 26
Hence the value of n and YZ are 13 and 26 respectively

Minato drove 390 miles. Part of the drive was along local roads, where his average speed was 20 mph, and the rest was along a highway, where his average speed was 60 mph. The drive took 8 hours. What distance, in miles did Minato drive along local roads?
Answer:
45 miles.
Step-by-step explanation:
Given that the:
Total distance covered = 390 miles
Total time = 8 hours
Let the distance covered along the local way = L
And the distance covered along the highway = H
Along with local way,
Speed = distance/ time
20 = L / T
T = L /20 .... (1)
Along the highway,
Distance covered H = 390 - L
Let the time = t
Speed = distance/time
60 = (390 - L)/t
t = ( 390 - L)/60
But total time = T + t
That is
8 = L/20 + (390 - L)/60
The LCM at right hand side will be 60
8 = ( 3L + 390 - L )/60
Cross multiply
480 = 2L + 390
Collect the like terms
2L = 480 - 390
2L = 90
L = 90/2
L = 45 miles.
Therefore, the distance Minato drive along local roads is 45 miles

Df = 9x -39 find EF.
DE =47
Greetings from Brasil....
Looking at the figure we can say that:
DF = DE + EFDF = 9X - 39
DE = 47
EF = 3X + 10
inserting these data in the 1st expression....
DF = DE + EF
9X - 39 = 47 + (3X + 10)
9X - 39 = 47 + 3X + 10
9X - 3X = 57 + 39
6X = 96
X = 96/6
X = 16
EF = 3X + 10 anb X = 16, so
EF = 3·16 + 10
EF = 48 + 10
EF = 58Find X. Need help ASAP
Answer:
A
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
the product of the external part and the whole of the secant is equal to the square of the tangent, that is
48(48 + x) = 60² = 3600 ( divide both sides by 48 )
48 + x = 75 ( subtract 48 from both sides )
x = 27 → A
