Mean weight of the bag of pears = u = 8 pounds
Standard deviation = s = 0.5 pounds
We have to find what percentage of bags of pears will weigh more than 8.25 pounds. This can be done using the z score.
We have to convert x = 8.25 to z scores, which will be:
z score = 0.5From the z table, the probability of z score being greater than 0.5 is 0.3085
Therefore, the probability of a bag to weigh more than 8.25 pounds is 0.3085
Thus 0.3085 or 31% (rounded to nearest integer) of bags of pears will have weight more than 8.25 pounds at the local market.
Answer:
9
Step-by-step explanation:
Total initially in bookstore = 45
Sold 13copies, remaining copies = 45-13= 32
Sold 23 copies again, remaining copies = 32-23 = 9
Copies left = 9
Let's start his with some trigonometry
Cos60=x/30
X=15
Now we can use Pythagorean therom
15^2+b^2=30^2
B(y)= 25.98
If you had 25 buttons ( red coloured) and 77 buttons (blue coloured). Half of the blue ones melted due to a supernova in the Atlantic ocean. Multiply red and blue buttons :)
Answer:
107 more girls will do gym on Saturday than Thursday and Friday altogether
Step-by-step explanation:
300 girls will do gym on Saturday.
100 girls did gym on Thursday
and 93 girls did gym on Friday.
now,
300 - (100 + 93)
300 - 193 = 107
