Answer:
42.7%
Step-by-step explanation:
Correlation is a statistical measure of inter relationship between two variables' co movement.
Correlation coefficient denotes the direction & extent by which two variables' (same or opposite) movement is linked to each other.
Coefficient of determination = r^2 symbolises percentage of variation in one variable, that can be explained by variation in other variable.
So, in this case r^2 = (0.654)^2 = 0.427716 ; Hence approx 42.7% variation in one variable can be explained by variation in other.

One angle of an isosceles triangle measures 132º. Which other angles could be in that
isosceles triangle? Choose all that apply.
An isosceles triangle is a triangle that has two sides and thus two angles the same amount. Triangles have 180 degrees, so if we subtract:
180 - 132 = 48, we do not have enough degrees to have a second 132° angle That leaves the 48° to be the angles to be split:
48 / 2 = 24°
So your answer is going to be 130-25-25 angle triangle.
*Just for reference, an example of an isosceles triangle having two possible answers? Let's say the given degree is 50o. Thus it could be one of the mirrored degrees (80-50-50), or it could be the non-mirrored angle (50-65-65)
Answer:
The other two angles of isosceles triangle will be 24° each.
Step-by-step explanation:
An isosceles triangleAn isosceles triangle is a triangle that has two sides and thus two angles opposite to the equal sides will be same .
Also Triangles have sum of all angle to be 180° , so if we subtract the given angle we get
180° - 132° = 48°,
So the total sum of angle remaining for other two angles will be of 48°
Therefore the sum of each angle will be
48° / 2 = 24°
So all angles of the isosceles triangle will be 132°-24°-24°angle triangle.

A sphere fits inside a cube with the sphere's diameter equal to the width of the cube, 20 centimeters. What is the volume of the cube not filled by the sphere? Round to the nearest cm³
A) 3813cm³
B) 3225cm³
C) 4079cm³
D) 3546cm³
The volume of the cube not filled by the sphere is 3811.209. Option A is the correct.
What is volume?The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic m.
The volume of sphere is found as;;
[tex]\rm V_{sphere}= \frac{4}{3} \pi r^3 \\\\ V_{sphere}= \frac{4}{3} \times 3.14 (10)^3 \\\\ V_{sphere}= 4188.79 \ cm^3[/tex]
The volume of cube is found as;
Volume of cube = Length x width x height
Volume of cube =20 x 20 x 20
Volume of cube = 8000
The volume of the cube not filled by the sphere is found by subtract the volume of the cube by the volume of the sphere.
V=8000 - 4188.790205
V = 3811.209
The volume of the cube not filled by the sphere is 3811.209.
Hence, option A is the correct.

I have around 40 minutes so its not too much of a rush, Thank you! :)
Answer:
P(number greater than 4) = 1/6(50)
In numbers 1 to 6 only 5 and 6 are greater than 4.
Hence, the probability that she will get a number greater than 4 is 2 out of 6 or 2/6.

There are 6 red marbles 4 blue marbles to yellow marbles. Sabrina picks 2 marbles without putting the first one back what is the probability that she picks a not yellow marble and then a blue marble.
Answer:
P = 3/11
Step-by-step explanation:
There are:
6 red marbles
4 blue marbles
2 yellow marbles.
So there are a total of 12 marbles in the bag, such that each one has the same probability of being randomly picked.
We want to find the probability that the first pick is not yellow (so it can be either blue or red), and the second pick is a blue marble.
Now there are two cases.
The first marble is red and the second blue
the first marble is blue and the second blue
We need to find the probability in each case.
The probability that the first marble is red is equal to the quotient between the number of red marbles (6) and the total number of marbles (12)
p = 6/12
Now, for the second draw, we need a blue marble, the probability in this case is the quotient between the number of blue marbles (4) and the total number of marbles in the bag (now there are 11, because one is already taken)
q = 4/11
The joint probability is equal to the product of the individual probabilities, then:
P₁ = p*q = (6/12)*(4/11) = 2/11
And for the other case, we draw two blue marbles:
For the first draw, the probability is:
p = 4/12
And for the second draw, now there are 3 blue marbles and 11 total marbles, then the probability is:
q = 3/11
The joint probability is:
P₂ = (4/12)*(3/11) = 1/11
The total probability is then:
P = P₁ + P₂ = 2/11 + 1/11 = 3/11

Find the values of x and y
Answer:
x = 54, y = 63
Step-by-step explanation:
117° and the left base angle are adjacent and sum to 180°
base + 117° = 180° ( subtract 117° from both sides )
base = 63°
Since the triangle is isosceles ( congruent legs ) then the 2 base angles are congruent , so y = 63
and x = 180 - (63 + 63) ← sum of angles in a triangle
x = 180 - 126 = 54

Round 8.157 to the nearest hundredth.
Answer:
I believe the answer is 8.16 pardon me if it's wrong.
Answer:
8.18
Step-by-step explanation:
First, note that 8.175 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 8
Fractional Part: 175
To round 8.175 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part.
We use the following rules to round 8.175 to the nearest hundredth:
A) If the last digit in the fractional part of 8.175 is less than 5, then simply remove the last the digit of the fractional part.
B) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.
C) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.
D) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.
With 8.175, rule B applies and 8.175 rounded to the nearest hundredth is:

How do i do this, i need to find an answer fast
Answer:
y = 5√3
x = 10√3
Step-by-step explanation:
From the given sides
Adjacent = 15
Opposite = y
Hypotenuse = x
Angle of depression = 30degree
Using the SOH CAH TOA identity
tan theta = opp/adj
tan 30 = y/15
y = 15tan30
y = 15(1/√3)
y = 15√3/3
y = 5√3
Similarly
cos theta = adj/hyp
cos 30 = 15/x
x = 15/cos30
x = 15 /√3/2
x = 30/√3
x = 30√3/3
x = 10√3

Step-by-step explanation:
An A grade will be given to students having at least 370 total test points. There is one more test to take before the semester is over. Lesha wants to know what she needs to score on the next test to finish with an A. Write and solve an equation to determine what score she needs to get. Explain your reasoning.
Answer:
95 points
Step-by-step explanation:
Given
[tex]n = 370[/tex] --- expected point
See attachment for points
Required
An inequality to determine the points needed
First, we calculate the points (p) Lesha has already accumulated.
[tex]p = Test\ 1 + Test\ 2 + Test\ 3[/tex]
[tex]p = 75 + 100 + 100[/tex]
[tex]p = 275[/tex]
Let the number of points needed be t.
So:
[tex]p + t = 370[/tex] ---- i.e. She must score a total of 370
Make t the subject
[tex]t = 370 -p[/tex]
Substitute 275 for p
[tex]t = 370 -275[/tex]
[tex]t = 95[/tex]

What is the distance between the two points 5,3 and (1,0)?
Answer: The distance between (5,3),(1,0) is 25units square.
Step-by-step explanation:
So, I usually plot the points, and conect them first.
And then I draw a right triangle, so draw two line that conect to the line that we need to find the distance, and form a triangle. Make sure that the line from point (5,3)(1,0) is the Pythagorean triples.
Next, you count the units of the two line that makes a right angle. which is 4 units for the first line, and 3 units for the second.
Thirdly, you plug the numbers into the Pythagorean equation, which is a^2+b^2=c^2 (plug it into a and b, it doesn't matter which number for which letter)
4^2+3^2=c^2
16+9=c^2
25=c^2
[tex]\sqrt{25}[/tex] = [tex]\sqrt{c}[/tex]
c=25
