Answer:
2100
Step-by-step explanation:
71 ->70
28 ->30
70 * 30 = 2100
Answer:
So we always look for to find a correlation. 0.81 is known as, Large Positive Linear Association. There are many variables, in this case, this "man" is part of other variables. So by removing HIM, the correlation goes from 8 to 9. It is still significant. However, it can be because of many reasons. Perhaps he has diabetes or cancer and was removed. *Hypothetically
Step-by-step explanation:
Answer:
y=11
x=8
Step-by-step explanation:
This is Elimination
2x+2y=38
Subtract 2x on both sides 2y=-2x+38
Then Multiply 2(y=x+3) which equals 2y=2x+6
Solve by Elimination
2y=-2x+38
2y=2x+6
add the y's and since the x's are different those cancel out, then add 38 and 6.
then you do the equation 4y=44
divide both by 4
y=11
then you do 11=x+3
subtract 3 on both sides
x=8
and there you go
I hope this is how you wanted it solved
This question can be solved using 2 equations since there
are 2 unknowns. First, let x = price of the tennis ball and y = price of the
baseball. The resulting equations are: (1) 5x +3y = 23.75 and (2) 2x + 7y =
31.25. Solving the 2 equations simultaneously, you get, x = 2.5 and y = 3.75.
The price of the baseball is then $3.75.
