Answer:
B, C and E
Step-by-step explanation:
1) Proving that opposite sides have equal slopes as they are parallel also
2) Proving that opposite sides are parallel and equal
Steps:
1. Do a proportion
X/20=35/100
2. Do 35 times 20 which equals 700
3. Do 700 divided by 100
4. Your answer is
7
Answer:
4/7
Step-by-step explanation:
the probability that a girl will win free popcorn = number of girls / sum of boys and girls
sum of boys and girls = 4 + 3 = 7
4/7
34km/h*2.5 hours=85km
30km/h*7.3 hours=219km
This makes a right triangle, so you plug it into the Pythagorean Theorem. The result is 234.92km from Port Cassett.
The probability that at least one of them has been vaccinated is equal to 98.5% if 65% of the people have been vaccinated.
Considering P to be the probability that at least one is vaccinated and q to be the probability that none of the four are vaccinated; the sum of all the probabilities must equal 1; therefore,
P = 1 - q
As 65% of the population is vaccinated, therefore 35% are not vaccinated. Thus any person has a probability of 0.35 of not being vaccinated;
q = 0.35^4 = 0.015
P = 1 - 0.015
P = 0.985
Converting it into percentage;
P = 0.985 × 100 = 98.5%
Therefore the probability that at least one of them has been vaccinated is calculated to be 98.5%
