Answer:
The cross product property
Step-by-step explanation:
The cross product property also known as cross multiplication is a method in math that is most of the time used in solving problems involving ratios usually in a big X form across the equal sign between two ratios.
It is done by multiplying the numerator of the left ratio by the denominator of the right with an equal to the multiplication of the numerator of the right ratio by the denominator of the left.
Answer is 16:40
Add up the parts of the sweets so 2+5=7.
Then with the total amount (56)/7=8.
8x2= 16
8x5=40
Answer:
<2 = 90
Step-by-step explanation:
If the lines are perpendicular, the angles are 90 degrees
Remember that, for independent events, the probability that both occurr is the product of the individual probabilities.
a) Probability of being contacted: 78% = 0.78
Probaility of refusing: 1 - 22% = 1 -0.22 = 0.78
Combined probability: 0.78*0.78 = 0.6084
b) The probability of failing to contact or making contact and not geeting them to agree 1 - the probability of contacting and getting them to agree.
The probabilityof contacting and getting them to agree is 0.78*0.22 = 0.1716
The the answer to this question is 1 - 0.1716 = 0.8284
