Answer: the answer is : calico crayfish
Step-by-step explanation:
AB = midsegment
ON = 2 × AB
5x + 7 = 2 × 3x
5x + 7 = 6x
x = 7
But the midsegment = 3x
Midsegment = 3 × 7
Midsegment = 21
Many when you solve it it works out perfectly.
Answer:
The proportion is 2/7 = 12/42
x = 12
The answer is 12
Answer:
P(R) = 0.14
P(I) = 0.16
P(D) = 0.315
Step-by-step explanation:
Let Democrat = D
Republican = R
Independent = I
If 45% are Democrats, 35% are Republicans, and 20% are independents, then
Total registered voters = 100
In an election, 70% of the Democrats, 40% of the Republicans, and 80% of the independents voted in favor of a parks and recreation bond proposal. That is,
D = 0.7 × 45 = 31.5
R = 0.4 × 35 = 14
I = 0.8 × 20 = 16
If a registered voter chosen at random is found to have voted in favor of the bond, what is the probability that the voter is
a Republican:
P(R) = 14 /100 = 0.14
an Independent
P(I) = 16/100 = 0.16
a Democrat
P(D) = 31.5/100 = 0.315
