Answer:
81
Step-by-step explanation:
Assuming the ramp is against a wall or building at a 90 degree angle, then the 3 angles formed by the triangle within the ramp and wall are 9 +90 + x = 180 so 99 + x = 180 so x=81
Answer:
I think its A
Step-by-step explanation:
If you subtract 500 from 127.38, you get 372.62. And then subtract 38.26, and you get 334.36. Then you add 25 dollars to that number and you get 359.36.
165 / 11 = 15 22/11= 2 so 11 is the least common multiple
Just imagine having 6 one blocks. Then you have 7 groups of those 6 one blocks. Then that's it!
Answer:
85.56% probability that less than 6 of them have a high school diploma
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they have a high school diploma, or they do not. The probability of an adult having a high school diploma is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
50% of adult workers have a high school diploma.
This means that
If a random sample of 8 adult workers is selected, what is the probability that less than 6 of them have a high school diploma
This is P(X < 6) when n = 8.
In which
85.56% probability that less than 6 of them have a high school diploma
