Answer:
{2, 4}.
Step-by-step explanation:
A = {1, 2, 3, 4, 5} and B = {2, 4}.
A ∩ B?
This means intersection or what is in common
A ∩ B = {2, 4}.
Answer: First yellow is y-1 the third yellow will be y-3
Second Blue will be b2
The first green will be g-2 and the fourth green will be g-4
Step-by-step explanation: It's legit just going by the color but instead of saying the full color they use the first letter and then just goes up by 1 each time. That's what I think the answer would be.
Answer:
Step-by-step explanation:
Given
Stot A:
Defective = 3%
Store B
Defective = 4%
Required
Determine the probability a product received is defective.
First, we calculate the probability that the defective product is from store A
Convert to decimals
Next, we calculate the probability that the defective product is from store B
The product may come from either stores.
So, the probability of having a defective product is:
The number of students would not change between before the test and after the test. 3+8 and 4+7 both = 11 so finding out how many students would equal one ratio can then be used to find how many equal 3 and 8.
If 92 students are equal to 4 in the ratio, then 1 in the ratio is worth 23 students. This is important as then when you times 23 by 7 you find out how many students there are in the regular maths class, 161 students. Plussing these two together gives you a total of 253 students.
Using this 253 you can divide it by 11 to find out how much 1 number would be in the ratio, it equals 23. Using this you can then times 23 by both 3 and 8 to find the original class sizes, 3x23 = 69, and 23x8 = 184.
Making the origional class size of the advaced class 69 studnets, and the regular maths class size 184.
12.5 is greater than 1.25
