The insurance period must be chosen so that the probability of a microchip failure within that period is 4%. Reference to a standard normal distribution table shows that the z-score for a cumulative probability of 4% is -1.75.
Let the insurance period be X months:
-1.75 = (X - 93)/3.8
-6.65 = X - 93
X = 83.35 months.
The answer is 83.35 months.

Answer: c 5 cm
Step-by-step explanation: 40 - 35 is 5 cm
Answer:
22cm,24cm,24cm
Step-by-step explanation:
Let us call one of the other sides x
the shortest side = 2x-26
in an isosceles, 2 sides are equal (x in this case)
so we now have sides of x,x and 2x-26
form an eqution from this.
4x-26=70
4x=96
x=24
24 x 2 = 48 - 26 = 22
thus, the shortest side is 22cm and the other sides are both 24cm
