Determine the correlation coefficient (r) for the linear relationship below.
Answer:
X Values
∑ = 53.5
Mean = 10.7
∑(X - Mx)2 = SSx = 151.086
Y Values
∑ = 6.9
Mean = 1.38
∑(Y - My)2 = SSy = 3.788
X and Y Combined
N = 5
∑(X - Mx)(Y - My) = 23.711
R Calculation
r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))
r = 23.711 / √((151.086)(3.788)) = 0.9911
So r= 0.9911 or 99.11%
A coin has two sides: heads and tails. A die has six sides, numbered 1 through 6 . If you flip the coin and roll the die, what is the probability that you flip ''heads'' and roll a number less than 3?
Answer:
Step-by-step explanation:
A number less than 3 is 2 or 1 which is 2/6 of the time
A coin can land on either side with a probability of 1/2
P(h and <3) = 1/2 * 2/6 = 1/6
This is exactly what you got.
An urn contains: 2 yellow balls, 1 red ball and 3 green balls.
We draw a ball:
What is the probability of getting:
1) a yellow ball:
2) a red ball:
3) a green ball:
4) a red ball or a green ball?
Answer:
Step-by-step explanation:
2 yellow balls
1 red ball
3 green balls
So in total there are 6 balls all together
1) 2/6 = 1/3
2) 1/6
3) 3/6 = 1/2
4) 3+1 = 4 4/6 = 2/3
Answer:
My big green balls is the answer because there big and large and can probably get in the way.
The answer is green also its just a joke.
Mr. Alvarado needs 15 1/8 pounds of chicken feed to fill his feeder. He has one bag of chicken feed that weighs 3 1/2 pounds and another bag of chicken feed that weighs 2 3/4 pounds. How many more pounds of chicken feed does Mr. Alvarado need to fill the chicken feeder?
A: 9 1/8 Lbs
B: 8 7/8 Lbs
C: 9 7/8 Lbs
D: 6 1/4 Lbs
Answer:
B: 8 7/8 Lbs
Step-by-step explanation:
answer = [tex]15\frac{1}{8} -3\frac{1}{2} -2\frac{3}{4}[/tex]
step 1 find a common denominator
common denominator - 8
* apply *
[tex]\frac{1^*^1}{8^*^8} =\frac{1}{8} \\\\\frac{1^*^4}{2^*^4} =\frac{4}{8} \\\\\frac{3^*^2}{4^*^2} =\frac{6}{8}[/tex]
now we have
[tex]15\frac{1}{8} -3\frac{4}{8} -2\frac{6}{8}[/tex]
step 2 make each fraction a improper fraction
We can do this my multiplying the big number by the denominator and adding that to the numerator.
[tex]15*8=120\\120+1=121\\\frac{121}{8} \\\\3*8=24\\24+4=28\\\frac{28}{8} \\\\2*8=16\\16+6=22\\\frac{22}{8}[/tex]
now we have
[tex]\frac{121}{8} -\frac{28}{8} -\frac{22}{8}[/tex]
Now we can subtract
remember when subtracting fractions you only subtract the numerators. ( so we keep the denominator as 8 )
so 121 - 28 - 22 = 71
so the answer is [tex]\frac{71}{8}[/tex]
finally we want to change the answer back into a mixed fraction
To do this we divided 71 and 8
8 can go into 71 8 times
8 * 8 = 64
71 - 64 = 7
We're left with [tex]8\frac{7}{8}[/tex]

4. The ratio of skateboards to bikes is 3:1.
If there are 12 skateboards, how many
bikes are there?
A 1
B 2
C3
D4
Answer quick PLZZ no website
Answer:
D
Step-by-step explanation:
3 represents skateboards and 1 represents bikes. We need to get from 3 to 12 and 1 to the answer by using the same number you used to get from 3 to 12.
To get from 3 to 12 you multiply by 4
3*4=12
So let's go ahead and multiply 1 by 4 as well
1*4=4
Your ratio is now 12:4 and 4 stands for bikes so there are 4 bikes

Write an equation of the line that passes through the given point and is perpendicular to the given line. 1 (-6, -4); y = 3x + 1
Answer:
y= -1/3x - 6
Explain:
For the slope, you find the opposite reciprocal of the given slope. Then you plug in the given coordinates into the point-slope formula: y - y = m ( x - x ). So the expression would be y - (-4) = -1/3 ( x - (-6)). So the answer would be y = -1/3x - 6.

respectively. If the total number of fruits is 63, how many
plums are there?
Number of plums =
Answer: 36 plums
Step-by-step explanation:
1+4+2 = 7

63 = 7 units
divide by 7 on both sides
9 = 1 unit
plums = 4 units
4*9 = 36
36 plums

Can someone help me here.
Answer:
A
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
3x - 2y = 12
-2y = -3x + 12
2y = 3x - 12
y = 3/2x - 6
Slope is 3/2
Y-intercept is -6

In mathematics, WHOLE NUMBERS are the basic counting numbers 0, 1, 2, 3, 4, 5, 6, … and so on. Whole numbers are the real numbers which includes zero and all the positive integers. Whole numbers don't include negative numbers, fractions, or decimals.
Sheila works at a fine jewelry store and earns a commission on her total sales for the week. She earned $900 in commission this week. She sold $23,000 worth of jewelry to earn that commission. Express her rate of commissions a percent.
Answer:
3.913%
Step-by-step explanation:
We are given that Sheila earned is commission $900 for selling $23,000 worth of jewelry, and we are asked to find the rate of her commissions as a percent.
The rate of commissions would basically just be what percent of the money made does she get. Since Sheila sold $23,000 worth of jewelry and got $900 for doing so, her rate of commission would be:
900 ÷ 23,000 ≈ 0.03913
Which expressed as a percent is:
3.913%
So her rate of commissions would be 3.913%.
I hope you find my answer to be helpful. Happy studying.
Find the slope of the line that contains the
point (4, −9) and has a y intercept of 2.
Answer:
m = -¹¹/₄Step-by-step explanation:
The equation of a line with slope of m and y-intercept of b is: y = mx + b
b = 2 and line contains the point (4, -9), so:
-9 = m×4 + 2 {subtract 2 from both sides}
-11 = 4m {divide booth sides by 4
m = -¹¹/₄

perimeter of a rectangle is 42 CM if length is 6 CM then breadth
Answer:
15cm
Explanation:
the formula for calculating the perimeter of a rectangle is (length + breadth) ÷ 2. so, we can divide the given perimeter by 2 to find the sum of the length and breadth of the rectangle:
42 ÷ 2 = 21cm
now, since we know the length of the rectangle is 6cm, we can subtract it from the sum of the length and breadth:
21 - 6 = 15cm
thus, the breadth of the rectangle is 15cm.

Decide if the sequence is arithmetic, geomtric, or neither. After you determine the type of sequence find the term given below. 2, 8, 32, 128 . . . Find a subscript 10 space
Answer:
Geometric sequence
[tex]a_{10} = 524288[/tex]
Step-by-step explanation:
Given
[tex]a: 2,8,32,128...[/tex]
Solving (1): The type of sequence
To check for arithmetic sequence:
[tex]d = a_2 - a_1[/tex] --- common difference
[tex]d = 8 - 2 = 6[/tex]
[tex]d =a_3 - a_2[/tex]
[tex]d =32-8=24[/tex]
Both values of d are not the same; Hence, the sequence is not arithmetic
To check for geometric sequence:
[tex]r = \frac{a_2}{a_1}[/tex] --- common ratio
[tex]r = \frac{8}{2}=4[/tex]
[tex]r = \frac{a_3}{a_2}[/tex]
[tex]r = \frac{32}{8} = 4[/tex]
[tex]r = \frac{a_4}{a_3}[/tex]
[tex]r = \frac{128}{32} = 4[/tex]
All values of r are the same.
Hence, it is a geometric sequence
Solving (2): Find [tex]a_{10[/tex]
For a geometric sequence;
[tex]a_n = a_1 * r^{n-1[/tex]
[tex]a_{10} = 2 * 4^{10-1[/tex]
[tex]a_{10} = 2 * 4^9[/tex]
[tex]a_{10} = 524288[/tex]
