Gwar [14]

Answer:

19.80

Step-by-step explanation:

Given the equation :

y = a (e)^kt

If a = 100, y = 50, and k = -0.035, find t.

50 = 100(e)^(-0.035t)

50/100 = e^(-0.035t)

0.5 = e^-0.035t

Take the In

In(0.5) = - 0.035t

-0.693147 = - 0.035t

-0.693147 / - 0.035 = t

19.8042 = t

Hence, t = 19.80

musickatia [10]
<span>The options for this question are:
</span>

0.25

0.40

0.60

0.75

<span>Solution:

The maximum limit from the table is 182
And the minimum value is 177.

Therefore,
Using the probability concept,

P( x < 180 )  = (180 - 177) </span>÷ 182 - 177

P( x < 180 )  = 3 ÷ 5

P( x < 180 )  = 0.60
