= (0.98)^4 * 0.02 =  0.0184   or 1.84%

(b)  this will be (0.98)^10 =  81.70%

Suppose the y-intercept of an exponential function is positive and the common ratio (r) is greater than 1. For this graph, as x
Anna11 [10]

Answer:

Increase (A)

Step-by-step explanation:

If the common ratio is greater than 1, that means the y-value increases as the x-value increases.

If the common ratio is 1, that means the y-value stays the same as the x-value increases.

If the common ratio is between 0 and 1, that means the y-value decreases and approaches 0 ad the x-value increases.

Because the common ratio is greater than 1, the answer is A, increases

The mean of the data set is 15.What number is missing? 9,12,16,18,23
maxonik [38]

The number 12 is missing in the data set.

<u>Step-by-step explanation</u>:

  • The numbers are 9,12,16,18,23.
  • The missing number is assumed to be 'x'

Mean = Sum of the integers / Total number of integers.

15 = (9+12+16+18+23+x) / 6

15 = (78+x) / 6

90 = 78+x

x = 90-78

x = 12
