To find the probability of picking a blue marble, first we add all the marbles together:
28+21+23+10=82

since there are 23 blue marbles in the bag out of a total of 82 marbles, the probability of picking a blue marble is 23/82.

P(blue)= 23/82

hope this helps

PLEASE HELP !!!
katen-ka-za [31]

Answer:

final cost of 3 pounds: <u>  8 dollars  </u>

final cost of p pounds: <u>   3.75p - 3.25  dollars  </u>

Step-by-step explanation:

Each pound costs $3.75, so 3 pounds cost 3*3.75 = 11.25 dollars. Subtract off the $3.25 to get the final cost to be 11.25-3.25 = 8 dollars. This takes care of the first part.

For the second part, the expression for the final cost is 3.75p - 3.25; where the 3.75p is the cost before the coupon is applied. If you plugged p = 3 into that expression, you should get 8 as a result. The variable p is some positive whole number. It's a place holder for the number of pounds of apples.

Ally's Fitbit tells her she has completed 73% of her goal for number of steps taken
iris [78.8K]

Answer:

7416.8

Step-by-step explanation:

5,840 x 127%

Since she's 73 percent of the way there, we need to add the last 27 percent as well as put a one in front so it will work.

127%

Because this is not just 7416 steps you should consider rounding it if your teacher asks you to.
