Answer:
x= -5
Step-by-step explanation:
when you add like terms to a different side you change the sign so instead of adding -7 to -12 it would be 7-12 which is -5
Answer:
B
Step-by-step explanation:
The diagram shows four points through which the line of proportional relationship should pass. One of these points has coordinates (8,28).
The line representing proportional relationship is always straight line passing through the origin and has the equation
where k is the coefficient of proportionality.
Substitute coordinates of known point into the equation:
so the coefficient of proportionality is equal to
Given:
principal 15,000
term 9 years
rate 8.5%
Interest = Principal * Interest Rate * Term
I = 15,000 * 8.5% * 9
I = 11,475
Total = 15,000 + 11,475 = 26,475 on date of maturity
Interest = 15,000 * 8.5% * 2
I = 2,550
Total = 15,000 + 2,550 = 17,550
amount withdrawn = 4,000
Penalty = 4,000 * 8.5 % * 6/12
P = 170
Net amount = 17,550 - 4,000 - 170 = 13,380
I = 13,380 * 8.5% * (8-2)
I = 6,823.80
Total = 13,380 + 6,823.80 = 20,203.80 total amount on maturity.
The probability that a sample of size n will have a mean,
, less that a given value, X, where the population mean,
, and the population standard deviation,
, is known is given by:
Therefore, the required probability is given by:
