50 miles is her total length of drive
3/8 -> 6/16
5+16 = 21
21/16 = 1 5/16
1 5/16 in shorter
Answer:
B.The mean and standard deviation have the values of mu equals 0and sigma equals 1
Step-by-step explanation:
The mean and standard deviation have the values of µ = 0 and σ = 1.
This is the requirement for any normal distribution curve to fulfil in order to be a standard normal probability distribution.
Answer:
h(d)= -2d^2 +4d +6
Step-by-step explanation:
Vertex (1,8)
Landing Point (3,0)
Applying the vertex formula, a quadratic equation can be described by its vertex v(x,y) as follows:

Since the vertex in this situation is at v (1,8):

To solve for 'a', apply the other given point (landing point) into the equation:

Expanding the equation yields:

Answer:
He must invest R297 521 today.
Step-by-step explanation:
The compound interest formula is given by:

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Banabas must pay his ex-wife an amount of R350 000 in two years’ time.
This means that 
Interest rate of 8.15% per annum compounded monthly:
This means that
.
Amount he must invest today:
This is P. So




He must invest R297 521 today.
