Answer:
E
Step-by-step explanation:
Irrational means cannot be put into a fraction. Or random repeating decimals is how I remember it.
√48 can be simplified to equal 4√3. √3 cannot be put into fraction form.
Answer:
240 girls
Step-by-step explanation:
Let number of girls be x.
160:x = 2:3
Multiply right side by 80--> 160:x = 160:240
x=240.
So there are 240 girls.
Answer:
always
Step-by-step explanation:
Indirect proof.
Answer:
The Graph D) is correct
Step-by-step explanation:
Let, x be length of cube and y is volume of cube
The volume of cube is given by
Volume =
Such that, all the sides of cube are equal
We can write as y=
Thus, The Graph D) is correct
Answer:
There is a 59.87% probability of randomly selecting 10 production employees on a cold winter day and finding that none of them are absent.
Step-by-step explanation:
For each employee, there are only two possible outcomes. Either they are absent, or they are not. This means that we can solve this problem using the binomial probability distribution.
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 combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
We want to find P(X = 0). So:
There is a 59.87% probability of randomly selecting 10 production employees on a cold winter day and finding that none of them are absent.
