<span>Well correlation can range from -1 to 1, with 0 being no correlation at all
</span>
<span>so -.015 is very close to 0, you would be not confident at all. This means your prediction is no better than a random guessing.</span>
Answer:
He will need to save $295
Step-by-step explanation:
he needs 450 and he has 155, so all you would do is subtract 155 from 450 and you get the rest he needs which is 295
The expected value should be a 1/3 change because you have three coins each , then 1/6 altogether change or randomization the most realistic highest expected value is you paying them 2$
Answer:
5.33lb of candy
Step-by-step explanation:
First, you'd need to set up a proportion.
4 pounds x poinds
----------- = -------------
9 dollars 12 dollars
Then, cross multiply.
9x = 4(12)
9x = 48
x = 48/9
And your answer is x = 5.33!
Hope I helped! ☺
Answer: (b) 48 cm
==========================================================
Explanation:
Divide the perimeter of the square over 4 to get the side length s.
s = P/4
s = 48/4
s = 12
The side length of the square is 12 cm. This leads to an area of...
A = s^2
A = 12^2
A = 144
The area of the square is 144 square cm.
The rectangle is 4 cm^2 less than the square's area, so we know the rectangle has area 144-4 = 140 cm^2.
If the length of the rectangle is 14 cm, then the width must be
W = A/L
W = 140/14
W = 10
This is a 14 cm by 10 cm rectangle (note how 14*10 = 140)
The last step is to compute the perimeter of the rectangle
P = 2(L+W)
P = 2(14+10)
P = 2*24
P = 48
You can use the formula P = 2L+2W, but it's effectively the same thing.
The perimeter of the rectangle is 48 cm.
