1/3
Step-by-step explanation:
You add up the amount in each bag then you take the amount of green then that will be the answer but since there is 2 bags it is 1/3
First, find the z-score:
z = (value - mean) / sdev
= (275 - 280) / 15
= - 0.33
In order to use a standard normal table, we need a positive z-score:
P(z < -0.33) = 1 - P(z < 0.33)
Looking at the table, we find P(z < 0.33) = 0.6293
Therefore:
P(z < -0.33) = 1 - 0.6293 = 0.3707
Hence, you have a probability of about 37% <span>that a randomly selected pregnancy lasts less than 275 days.</span>

Step-by-step explanation:
In store A, the each tulip bulbs costed
11 / 5 = $2.2
In store B, each tulip bulbs costed
13/6 = $2.1
The answer is he will make $300 commission for 25 TV sets sold. The first thing you need to do is find out how much commission he makes on each TV. So we take $120 and divide by 10% and that gives us $12. So $12 is the amount of commission per TV. Then we just need to multiply the $12 by 25 TV sets. That gives us the answer of $300 commission total.
A second way to solve this problem is by taking the $120 and multiplying that by the 25 TV sets. That gives you $3,000 total for the 25 TV sets. Then you just divide the 10% commission Mike will make. That also gives you the answer of $300 commission.
The answer would be a 3x-4y=-10
