Answer:
C
Step-by-step explanation:
Find P(X > 67)
using ( x - mean )/ standard deviation again you will get thi(1) which is equal to 0.8413....
0.8413 x 5000 is 4207

Answer:
-$95
Step-by-step explanation:
If he deposits $230 in his bank account, that means he has $230 in it.
Then in order to withdraw $325 from his bank account, you have to subtract the two numbers.
So 230-325= -95
So thats why he has -$95 of value left in his bank account.
Answer:
B,
Step-by-step explanation:
This problem is essentially asking one to envision a line passing through the set of points on the coordinate plane, then to find the constant of proportionality of that line. The constant of proportionally, also known as the rate of change, or the slope, is a number that can be used to describe the range that happens between points on a line. The following formula can be used to find the slope of a line passing through a set of points.
Where the points () and () are points on the line.
As one can see, on the given coordinate plane, the points (), and () are on the coordinate plane. Substitute these points into the formula to find the slope of the line, then simplify to evaluate the equation and find the slope,
(), ()
If the Earth were a flat surface, then 9 miles east and 12 miles north would be
the basis of a right triangle, and the straight-line route would be the hypotenuse.
We could use the Pythagorean Theorem to find the straight-line distance.
A² + B² = C²
C² = (9)² + (12)²
C² = 81 + 144
C² = 225
C = √225 = <u>15 miles</u>
That's Choice-'H'.
