How to find correlation coefficient with standard deviation.
Answer:
Another way to calculate the correlation coefficient (r) is to multiply the slope of the regression line by the standard deviation of X and then divide by the standard deviation of Y.
What is the value of this expression when c = 3 and d = 7? 15+c2⋅d−c3
Answer:
The value of this expression is 48
Step-by-step explanation:
15 + c2 * d - c3
c = 3
d = 7
Substitute the values of c and d
15 + (3)2 * 7 - (3)3
Multiply the parenthesis first
15 + 6 * 7 - 9
Now multiply 6 and 7
15 + 42 - 9
Now add 15 and 42
57 - 9
Now subtract
= 48
Answer:
48
Step-by-step explanation:
When you write out the problem it should look like this
15+c⋅2⋅d-c⋅3
or in other form
15+3⋅2⋅7-3⋅3

Answer:
Angle 5=60°
Step-by-step explanation:
Angle 4 = 180°-116° (adj angles on a str line)
= 64°
Angle 5 = 180°-64°-56° (angle sum of triangle)
= 60°
Answer:
<5 = 60 degrees
Step-by-step explanation:
<4 = 180-116 = 64 degrees
64 + 56 + <5 = 180 degrees

a table is 60 cm in diameter. A tablecloth hangs 65cm all around. how much lace trim is needed to edge the cloth
The circumference of a circle is the total length of the boundary of the circle. So that the length of lace trim required is 597.1429 cm.
The diameter of the table is 60 cm, which has 65 cm tablecloth hanging on its sides. The diameter of the cloth required would be the length from one side to the other side. So that the total diameter of the tablecloth is:
= 60 cm + 2*65 cm
= 60 cm + 130 cm
= 190 cm
The diameter of the tablecloth required is 190 cm.
Thus to determine the circumference of the tablecloth, we have;
C = 2[tex]\pi[/tex]r
= [tex]\pi[/tex]D
where D is the diameter of the tablecloth.
C = [tex]\frac{22}{7}[/tex] x 190
= 597.1429
C = 597.1429 cm
Therefore, the length of lace trim required for the edge of the tablecloth is 597.1429 cm.

Answer:
1. No
2. No
3. No
4. Yes
Step-by-step explanation:
Insert each y value into the equation. If it equals -14, then it is a solution to the equation. The only one of these y values that is a solution is the last one, -2.
8 * (-2) = -16
-16 + 2 = -14
So y = -2 is a solution.

Answer:
They are proportional
Step-by-step explanation:
Proportionality:
They are proportional because the cost is going up by 10 the entire time and the hours rented is going up by 2 the entire time.
Graphing:
Go to the 2 on the x-axis (horizontal line)
Go up to the 20 on the y-axis (vertical line)
The points to graph are:
(2,20)
(4,30)
(6,40)
(8,50)
I put a pic of what your graph should look like below!
Answer:
To plot the graph put the hours along the x axis and the cost on the y axis. Its a positive realationship because when the hours go up the cost goes up to, it isn't proportional because both values don't go up at the same rate.

Answer:
A = 2r²
Step-by-step explanation:
A square is a rhombus with equal-length diagonals. A square inscribed in a circle has diagonals equal to the diameter of the circle: 2r.
The area of a rhombus is half the product of the lengths of its diagonals. Hence the area of our square is ...
A = (1/2)(2r)(2r)
A = 2r²
Answer:
2
Step-by-step explanation:
r=1/2s[tex]\sqrt{2}[/tex]
2r=s[tex]\sqrt{2}[/tex]
2r/[tex]\sqrt{2}[/tex]=s remove [tex]\sqrt{2}[/tex] denominator by multiplying with [tex]\sqrt{2}[/tex]/[tex]\sqrt{2}[/tex]
2[tex]\sqrt{2}[/tex]r/2 -- simplify , 2 cancels
s=r[tex]\sqrt{2}[/tex]
so area = (r[tex]\sqrt{2}[/tex])^2
A(r)= 2r²

Black Friday sale. One item was
originally $75. How much was it on
sale for
Answer:
$60
Step-by-step explanation:
20% off means 80% of original price
80% = 8/10 or 0.8
75 * 0.8 = 60
you could also do 20% = 1/5, 1/5 of 75 is 15, 75-15=60

3^x X 9^4 = 3^n
Find n in terms of x
Answer:
n = x + 8
Step-by-step explanation:
Using the rules of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
Then
[tex]3^{x}[/tex] × [tex]9^{4}[/tex] = [tex]3^{n}[/tex]
[tex]3^{x}[/tex] ×[tex](3^2)^{4}[/tex] = [tex]3^{n}[/tex]
[tex]3^{x}[/tex] × [tex]3^{8}[/tex] = [tex]3^{n}[/tex]
[tex]3^{x+8}[/tex] = [tex]3^{n}[/tex]
Since bases on both sides are equal, both 3, then equate exponents
n = x + 8

y=−13x+14
A. -1/3
B. 1/4
C. 1/3
Answer:
see below
Step-by-step explanation:
y = -13x+14
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -13 and the y intercept os 14
If you mean y = -1/3x + 1/4
The slope is -1/3 and the y intercep is 1/4
Answer:
-1/3 is the slope because the equation is in a form of y =mx + c, where m is the slope

How is a trapezoid different from a rectangle?
A. It’s is not a closed polygon
B. It has five legs and a diagonal
C. It has one pair of parallel sides
D. It has all pairs of parallel sides
Answer:
C.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
A can't be right because rectangles and trapezoids are both closed polygons.
B can't be right because both shapes can't even have 5 legs.
C is right because triangles only have one pair of parallel sides and rectangles have two pairs.
D trapezoids don't have two pairs of parallel sides because two sides intersect eventually.
