Answer:
0.23
Step-by-step explanation:
Given the data:
____(x) __(y)__(x - m1) /s1 ___(y-m2) /s2
1 ___6 ___8__ - 0.2 _______0.625
2 __5 ___ 5__ - 0.7________ - 1.25
3 __9____6__ 1.3 ________ - 0.625
4__ 4____ 7__ - 1.2 ______ 0
5__ 8 ____9 _ 0.8 _______ 1.25
For English :
Mean score(m1) = 6.4
Standard deviation (s1) = 2.0
For Science :
Mean score (m2) = 7.0
Standard deviation (s2) = 1.6
n = number of observations = 5
Correlation Coefficient (r) :
r = 1/(n - 1) Σ[((X - m1) / s1) * ((Y - m2) /s2)]
(-0. 2 * 0.625) + (-0.7 * - 1.25) + (1.3 * - 0.625) + (-1.2 * 0) + (0.8 * 1.25) = 0.9375
r = 0.9375/(5-1)
= 0.234
= 0.23
George bought 7 ounces of grapes for $3.36. What was the price of the grapes per
ounce?
Your answer is quite simple, really. All you have to do is divide $3.36 by 7 (The ounces of grapes he bought), and your answer should come out to be $.48, to check if this is correct, you then should add .48, 7 times, or multiply it by 7. Which, is what I did. And that should bring you to 3.36!

Calculate the peak hour volume for six-15 minute periods with the following volumes: 125, 130, 135, 140, 145, 155
Answer:
The peak hour volume is 620
Step-by-step explanation:
Here, we want to calculate the peak hour volume
To calculate the peak hour volume, we need some information
Firstly we need to know that a period of 15 minutes refer to 1/4 of an hour
So, the given volume needs to be multiplied by 4 to get the peak hour value
Now back to the values given, we need the highest of them all
As regards the question, the highest of them all is 155
So the peak hour volume here would be 155 * 4 = 620
PLEASE HELP!!!!! Sebastian owns a food truck that sells tacos and burritos. He only has enough ingredients to make 122 tacos or burritos.Write an inequality that could represent the possible values for the number of tacos sold, t t, and the number of burritos sold, b b, that would satisfy the constraint.
Answer:
t+b<=122
Step-by-step explanation:
You know that the total is a maximum of 122, and it can be either tacos or burritos, so it is that.
Answer:
61/61 each
Step-by-step explanation:
you will have two left so 61 each. 60+60=120, 120+2=122

Y=-4 when x=32, find x when y=-0.375
Answer:
x = 3
Step-by-step explanation:
This can be set up as a proportion.
[tex]\frac{32}{-4} = \frac{x}{-0.375} \\[/tex]
Then, cross multiply -4x = -12. (The -12 came from multiplying 32 and -0.375). Divide both sides by -4 to get x = 3.
Consider the following equation.
3x + 5 = - 3y + 5
Step 1 of 2: Find the x-and y-intercepts, if possible.

the sum of X and 4 is greater than the difference of 2x and 3 find x
Answer:
x = 7
Step-by-step explanation:
x + 4 > 2x - 3
x by itself = 1x
1x + 4 > 2x - 3
Subtract 1x
1x - 1x + 4 > 2x - 1x -3 =
4 > 1x -3
Add 3
4 + 3 > 1x -3 +3 =
7 > 1x
1x is the same as x
7 = x

Lines AC and BD intersect at E. A figure. What is the measure of angle BEC?
Answer:
Angle BEC = 108°
Step-by-step explanation:
Vertical angles formed when two straight lines intersect are always congruent to each other. That is, the vertical opposite angles formed are of the same measure.
Angle AED = 108°
Angle AED and angle BEC are vertical opposite angles form by intersecting lines, therefore, angle AED = angle BEC.
Angle BEC = 108°

If f(2) = 13, which could be the equation for f (x)?
A) f (x) = x2 + 8
B) f(x) = 3x2 +1
C) f(x) = 2x3 + 5
D) f (x) = x2 + x
Only use letter in your answer choice!!!
the answer is B for this question
The equation for f(x) if the independent value is 2 will give a result of 13 is (x) = 3x² + 1
Functions and valuesGiven the expression f(2) = 13, we need to find the function such that when the input value is 2, the output value will be 13.
Using the function f(x) = x² + 8
f(2) = 2² + 8
f(2) = 4 + 8 =12
Using the function f(x) = 3x² + 1
f(2) = 3(2)² + 1
f(2) = 12 + 1 =13
Hence the equation for f(x) if f(2) = 13 is (x) = 3x² + 1

- it's a simplification process
- 4v-3 = -2v + 5
V =
Answer:
Hello! I hope Im correct! :)
Step-by-step explanation:
The answer should be v = -4
step 1: Add 4v to both sides.
-3=-2v+5+4v
step 2: simplify.
-3=2v+5
step 3: subtract 5 from both sides.
-3-5=2v
step 4: Simplify.
-8=2v
step 5: divide both sides by 2.
-8/2 = v
step 6: simplify.
-4=v
(V = -4)
Therefore the answer is V = -4Hope this helps! If you have any questions about these steps, feel free to ask! Have a Awsome day! :)
