Answer:
So the total is 400 and then you have 4 servings
so 400/4 = 100 cal per serving

1.5 cups of flour to 2 eggs

Answer:
hold up
Step-by-step explanation:
Answer:
81
Step-by-step explanation:
Since the question states that the only difference would be the length of the neighbor's pool then this is basically a ratio problem. Therefore, since the question provides 3 values and one variable we can solve this using the Rule of Three which takes the diagonal values multiplies them together, and divides by the last sole value to get calculate the variable like so...
243
volume <=====> 9 m length
x
volume <=====> 3 m length
(3* 243) / 9 = 81
Therefore, the volume of the neighbors pool will be 81
Answer:
0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year
Step-by-step explanation:
For each employee, there are only two possible outcomes. Either they survive the first year, or they do not. The probability of an employee surviving the first year is independent of other employees. This means that 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.
A San Francisco-based tech firm is able to keep 80% of its new employees after one year.
This means that 
Q1. What is the chance that two randomly sampled new employees will both be able to survive their first year
This is P(X = 2) when n = 2. So


0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year
