You want to replace the s with 150 in the equation and then just solve for t.
150=16√7t +62 subtract 62 from both sides
88=16√7t divide both sides by 16
5.5=√7t to get rid of the square root square both sides.
30.25=7t now divide both sides by 7
4.3 = t (approximately)
so at 4 weeks they will have sold 150 units.
3, 9, 27, 81, 343, 729, … is a geometric sequence because each term is obtained by multiplying 3 to the preceding term.
Answer:
a. 6 b. -2
Step-by-step explanation:
a. x^3 = 216
x = ³√216
x = 6
b. -n^3/4 = 2
-n^3 = 8
-n = ³√8
- n = 2
n = -2

Answer:
0.966
Step-by-step explanation:
Given that:
Probability of DVD player breaking down before the warranty expires = 0.034
To find:
The probability that the player will not break down before the warranty expires = ?
Solution:
Here, The two events are:
1. The DVD player breaks down before the warranty gets expired.
2. The DVD player breaks down after the warranty gets expired
In other words, the 2nd event can be stated as:
The DVD does not break down before the warranty gets expired.
The two events here, have nothing in common i.e. they are mutually exclusive events.
So, Sum of their probabilities will be equal to 1.
