Answer:
133.33 years
Step-by-step explanation:
Given that:
Principal = $500
Interest rate (r) = 1.5% = 0.015
Triple amount of principal = $500 * 3 = $1500 = final amount (A)
Number of years (t) =?
Using the relation :
A = P(1 + rt)
1500 = 500(1 + 0.015t)
1500 / 500 = 1 + 0.015t
3 = 1 + 0.015t
3 - 1= 0.015t
2 = 0.015t
2 / 0.015 = 0.015t / 0.015
133.333 = t

Answer:
77.41
Step-by-step explanation:
4.6² + 7.5²= 77.41
Square root of 77.41:
√77.41
This is because it can not be simplified further!
Why?
Because we used the Pythagoras Formula which is a²+ b² = c².
This is also why we had to find the square root of 77.41.
Answer:
The sampling distribution is, p = center = 0.043
The standard deviation of the sample, s = 6.0015×10⁻⁴
The shape is normal
Step-by-step explanation:
Here we have the standard deviation of a sample proportion, given by the following relation;
The center = p = 4.3% or 0.043
The shape is found by the value of n×p hence;
114250 × 0.043 = 4912.75 > 10 and
n(1 - p) = 114250 × (1 - 0.043) = 109337.25 also > 10 hence the shape is normal.

6. p+12= x
7. i-7= x
8. r/3= x
9. z-1= x
10. y*19= x
x is NOT always the same, it is just a common variable representing the answer
