viva [34]

Answer:

30%

Step-by-step explanation:

If a football quarterback enjoys practicing his long passes over 40 yards and misses the first pass 40% of the time, but when he misses on the first pass, he misses the second pass 20% of the time. The probability of missing two passes in a row is 30%.

First pass: 40%

Second pass: 20%

40% and 20% combined/average is 30%.

Therefore, the probability of missing two passes in a row is 30%.

DiKsa [7]

Answer: Yes, Rita has enough wire to hang the picture frame.

Step-by-step explanation:

Since we have given that Rita hangs a picture frame of width 22 cm on the wall , the distance from the nail to the top edge of the picture frame is 8 cm, and she has 26 cm of wire to hang the picture .

She need wire only to hang the picture frame which 8 cm away from the nail, and she has 26 cm of wire to hang it .

And 26 > 8 i.e. 26 is greater than 8.

So, Rita has enough wire to hang the picture frame .
