100 is the correct answer
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>
Answer:
the answer is 6
Step-by-step explanation:
you take the absolute value for both of them which is 2 and 8 but you keep the negative still so it would be -2+8 which is 6
Answer:
Yes. Felix is correct.
Step-by-step explanation:
Find out how much ml does a can of lemonade have, I would assume its 330ml since I searched up the ml of a lemonade can.
Find out how much cans of lemonade there are in 2 packs of 8.
2 packs = 8 x 2 = 16 cans of lemonade
Now find out how much ml 16 lemonade cans equal to.
1 can of lemonade = 330ml
16 cans of lemonade = 330 x 16 = 5280ml
Now let's find 5 bottles of 1 litre.
1 litre x 5 = 5 litres.
5280 = 5 litres and 280ml
So Felix is correct about 2 packs of 8 cans is more than 5 bottles of 1 litre.
