Answer:
amount invested in the account that earns 10% interest = Rs 3500
amount invested in the account that earns 8% interest =Rs 5500
Step-by-step explanation:
Two equations can be derived from the question
x + y = 9000 equation 1
0.08x + 0.1y = 790 equation 2
x = amount invested in the account that earns 8% interest
y = amount invested in the account that earns 10% interest
multiply equation 1 by 0.08
0.08x + 0.08y = 720 equation 3
subtract equation 3 from 2
0.02y = 70
divide both sides of the equation by 0.02
y = 70 / 0.02
y = 3500
Substitute for y in equation 1
x + 3500 = 9000
x = 9000 - 3500 = 5500
General form is ax^2+bx+c, and to get there we need to factor using FOIL (First Outside Inside Last)
(2x-1)(x+5)
F (2x × x)= 2x^2
O (2x × 5) 10x
I (-1 × x) -x
L (-1 × 5) -5
now add them together
2x^2+10x-x-5
2×^2+9x-5
and because the equation is in the form
ax^2+bx+c b is equal to 9
THE ANSWER IS CHIPOTLE, CHICK-FIL-A, BURGER KING, MCDONALDS… ETC.
(REAL NOT FAKE)
Answer: (y-c)/m
Reasoning:
Subtract c from both sides [ y-c=mx+c-c ]
Divide m from both sides [ (y-c)/m=mx/m ]
Answer:
The 12th percentile is found on the LEFT side of the Normal distribution, so the z-score at the 12th
Use the z-table to answer the question.
percentile will be NEGATIVE
The Z-score is -1.175
