Answer: B) 2lb
Step-by-step explanation:
First, you must convert from mixed numbers to fractions, as following
Point diagrams divide a sample into different classes, and allow to observe the frequencies of each class.
In this case, the different weights of the grapefruit constitute the classes. From a sample of 9 grapefruit, some will weigh others weigh , etc.
We need to observe the dot diagram to know how many grapefruit we have and how many grapefruit we have. In other words, we need to know, in the diagram, how many points there are about class and how many points there are about class
Then, the total difference between all grapefruit of pounds and all grapefruit of pounds is calculated as follows:
n () - m () = W
Where
W: Weight difference
n: Quantity of grapefruit
m: Quantity of grapefruit of
Suppose that of the 9 total grapefruits, 3 of them weigh pounds and 2 of them weigh pounds. This is: n = 3 and m = 2
The difference in weight would be 2 pounds.
Answer:
0.8%
Step-by-step explanation:
Because they are two independent events, the final probability is the product of the probability of each event.
First event:
The complement of a student being male is that he is female.
Therefore, if 60% is male, the remaining 100% is 40%, meaning that 40% of the students are female.
Second event:
If she's taller than 5'4", we're told she has a 2% chance of being a woman.
Therefore the final probability is:
0.4*0.02 = 0.008
That is, the probability that it is female and that it is over 1.6 meters tall is 0.8%.
Answer:
Cereal A is a better option
Step-by-step explanation: If someone were to buy a 14-ounce box of cereal for $4.20 <--(Cereal A) and another person wants to buy the 12-ounce box for $3.90 <-- (Cereal B)You need to find how much one ounce costs. So, you have to divided $4.20 by 14 and that gives you $0.30 and so you do the same for Cereal B, $3.90 by 12 that gives you $0.33. Which one is less cheaper? Cereal A
12*24= 288
3/5 of 45 is 27.
