Answer:

probability is 4 / 13

Step-by-step explanation:

Total number of cards in a standard deck = 52 cards.

total number of diamonds = 13 cards

total number of queens = 4 cards.

We should remember that in 13 cards of diamonds there is one queen. so total diamonds and queens are = 13 + 3 = 16 cards

The probability that Jack picked a diamond or a queen

= 16 / 52 = 4 / 13

A woman who has recovered from a serious illness begins a diet regimen designed to get her back to a healthy weight. She current
WINSTONCH [101]

Answer:

a.) w = 103 * 1.08^t

b.) 3.5weeks

Step-by-step explanation:

If Her current weight is 103 pounds and she hopes to multiply her her weight each week by 1.08, then

her weight after 1 week = 103 * 1.08 = 103 * 1.08¹

Her weight after 2 weeks = [weight of week 1] * 1.08 = [103* 1.08] * 1.08 = 103 * 1.08²

Weight after 3 weeks= [weight of week 2] * 1.08 = [103 * 1.08 * 1.08] * 1.08 = 103 * 1.08³

Hence weight (W) after t weeks = 103 * 1.08^t

b.) If W = 135, Then

103 * 1.08^t = 135

1.08^t = 135/103

1.08^t = 1.31

Taking log of both sides,

log 1.08^t = log 1.31

t log 1.08 = log 1.32

t = log 1.32/log 1.08

t = 3.5 weeks.

Hence, it will take her 3½ weeks to get to 135pounds weight.
