Answer:
Carmen can make full servings.
Step-by-step explanation:
Given : Carmen mixes cups of water with
cups of juice to make punch.
Total quantity of punch Carmen made = total cup of water + cup of juice she mixes
Total quantity of punch Carmen made =
Solving , we get,
Total quantity of punch Carmen made =
taking LCM(2,8) = 8 , we get,
Total quantity of punch Carmen made =
Also, given She pours cup servings of punch.
Thus, cup of mixture makes 1 serving cup.
Using unitary method,
In unitary method we first find the value of a single quantity and then multiply it with the desired quantity.
1 cup of mixture makes serving cup.
cup makes =
cup makes =
Thus, She can make full servings.
Subtract 4 from both sides.
Subtract 4 from 36 to get 32.
Divide both sides by −8. Since −8 is <0, the inequality direction is changed.
Divide 32 by −8 to get −4.

The value is
Step-by-step explanation:
From the question we are told that
The probability of passing the test is
The sample size is n = 10
Generally the distribution of the comprehensive testing of equipment follows a binomial distribution
i.e
and the probability distribution function for binomial distribution is
Here C stands for combination hence we are going to be making use of the combination function in our calculators
Generally the probability that at least 9 pass the test is mathematically represented as
