X = boy count
x + 14 = girl count
x +x +14 = 86
2x + 14 = 86
2x = 72
x = 36
x + 14 = 50
There are 36 boys and 50 girls. Hope this helps!
Answer:
188 legs
Step-by-step explanation:
A game of legs!!
In this question, we are asked to calculate the number of legs of animals present in the question.
Let’s first identify the individual brands of animals present. We have ;
4 dogs, 7 bees, 5 cockroaches, 8 spiders, 3 deers, 4 boars and 2 antlers.
A dog has 4 legs; this means total number of legs contributed by the dogs to the pool will be 4 * 4 = 16 legs
A bee has six legs; total number of bees legs is thus 7 * 6 = 42 legs
A cockroach has 6 legs; total number of cockroaches legs is 6 * 5 = 30 legs
8 spiders have a total of 8 * 8 = 64 legs
3 deers, 4 boars and 2 antlers have 4 legs each making a total of 9 * 4 = 36 legs
The total number of legs present is thus; 36 + 64 + 30 + 42 + 16 = 188 legs
Answer: 0.206
Step-by-step explanation:
Given that :
Height of American men is normally distributed :
Mean height (μ) = 69.7 inch
Standard deviation (σ) = 2.8 inch
Probability that height of a randomly selected man is more than 72 inches
P(X > 72)
Obtain the standardized score (Zscore):
Zscore = (x - μ) / σ
Zscore = (72 - 69.7) / 2.8
Zscore = 2.3 / 2.8
Zscore = 0.8214285
Zscore = 0.8214
Using the Z probability calculator ;
P(Z > 0.8214) = 0.20571
Probability of selecting a man whose height is more Than 72 is 0.206
