From your statement, i can assume that the interest 6.5% is for yearly.
30 months = 2.5 years
1 year interest for 100 = 6.5
1 year interest for 12000 = 6.5/100 * 12000
= 780
2.5 years interest for 12000 = 780*2.5
= 1950
so the total amount that you have to pay
12000 + 1950
$ 13950
Answer:
70.06
Mean score = 70
Step-by-step explanation:
16% of students scored higher than 80 on a recent normally distributed exam the standard deviation is 10 what is the mean
For a normal distribution :
Zscore = (x - mean) / standard deviation
x = score
P(Z > 80) = 16% = 0.16 ; corresponding Zscore = 0.994 (Z probability calculator)
Therefore ;
0.994 = (80 - mean) / 10
0.994 * 10 = 80 - mean
9.94 = 80 - mean
Mean = 80 - 9.94
Mean = 70.06
Hence, the mean score = 70.06 = 70
Answer:
Find the equation of the line that is parallel to y=4x+1 and contains the point (1,1)
Substitute 1 for x and 1 for y in y=4x+1.
1=4(1)+1
The given point does not make the equation true.
Invalid Point
Step-by-step explanation:
Answer:
18.8496 units (rounded o1ff to four decimal places)
Step-by-step explanation:
Arc length = 2 × π × r × 
r (radius) = 12 units ÷ 2 = 6 units
Central angle = 180°
For our semicircle, the arc length = 2 × π × 6 × 
= 18.8495559215 units
Or 18.8496 units (rounded o1ff to four decimal places)
