Answer:
D) The standard deviation of the residuals
Step-by-step explanation:
Answer:
I'm pretty sure it's A.
Step-by-step explanation:
The formula is y=mx+b,
Where m is the slope
And b is the y intercept
You listed it with the numbers y= 2/5x - 1
So we know the y intercept is -1
We know the slope is 2/5, witch is 2 up and five to the right, due to rise over run.
So the correct graph is A.
Answer:
Step-by-step explanation:
The 90th term of the arithmetic sequence is 461
a90=a1+(90-1) x d
a90=16+89 x 5
a90=461
Simple, the answer to this is...
two angles that add up to be the sum of 90°
Now, a quick tip.
To know the difference between supplementary (180°) and complementary (90°) angles...
the s in supplementary can be viewed as an 8, while in complementary the c can be viewed as a 9....
Thus, your answer....C.
Answer:
let x = the number of nickels
the number of pennies can be represented by (56 - x)
.05x + .01(56 - x) = 1.52
5x + (56 - x) = 152 if in the above line we multiply both sides of the equation by 100
4x + 56 = 152
4x = 96
x = 24
There are 24 nickels and 56 - 24 = 32 pennies
24 nickels are worth 24 * 5 = $1.20 and 32 pennies are obviously worth 32 cents, so the total is 1.20 + 0.32 = $1.52
