Answer: The percentile is 89
Step-by-step explanation:
This question can be solved using concept for t tables
In a normal distribution the curve. 
The relationship between z score, mean and standard deviation is given by

So the z value according to this is given by the formula

From the z table we can infer that p value for z=+1.217 is 88.82
So 1750 is 89th percentile

For this case the vertex of the parabola is the point at which the parabola presents a minimum.
The parabola presents a minimum in this case, because the parabola opens upwards.
The vertex is then a minimum.
The vertex of the function is located in the following ordered pair:
(x, y) = (1, -1)
Answer:
(x, y) = (1, -1)
minimum
Option A
Answer:
case 1) 
case 2) 
Step-by-step explanation:
case 1) we know that
Using proportion

solve for z

case 2) we know that
Using proportion

solve for z

5x+3x=8x
2y+2y=4y
Answer : 8x+4y
Answer:
12/(7-4) + 5 * 3 = 19
Step-by-step explanation:
Given
Untrue Expression: 12 ( 7 − 4 ) + 5 3 = 19
Signs: +−×÷
Required
Use the given signs to make the equation true.
To solve this, the trial and error method will be adopted.
The trial and error method involves trying series of sign combinations in the given expression; whichever works is the right answer.
So, after few attempts the following makes the equation true
12/(7-4) + 5 * 3 = 19
To check if it's true or not; we simply expand the expression on the left hand side. This gives
12/3 + 5 * 3 = 19
4 + 5 * 3 = 19
4 + 15 = 19
19 = 19.
Hence, the sign combinations used in 12/(7-4) + 5 * 3 = 19 is correct.
