Answer:
Option b. 12 teaspoons.
Step-by-step explanation:
In the question it given :
1 cup = 16 tablespoons
1 tablespoon = 3 teaspoons
16 tablespoon = 48 teaspoons or 1 cup
A recipe calls for 1/4 cup of broth. Tabitha has only a teaspoon to measure broth.
1 cup broth = 48 teaspoons
1/4 cup broth = 48 × = 12 teaspoons
Tabitha should use 12 teaspoons of broth.
Answer:
P(X≤5)=0.5357
Step-by-step explanation:
Using the binomial model, the probability that x adults from the sample, are pessimistic about the future is calculated as:
Where n is the size of the sample and p is the probability that an adult is pessimistic about the future of marriage and family. So, replacing n by 20 and p by 0.27, we get:
Now, 25% of 20 people is equal to 5 people, so the probability that, in a sample of 20 American adults, 25% or fewer of the people are pessimistic about the future of marriage and family is equal to calculated the probability that in the sample of 20 adults, 5 people of fewer are pessimistic about the future of marriage and family.
Then, that probability is calculated as:
P(X≤5)= P(1) + P(2) + P(3) + P(4) + P(5)
Where:
Finally, P(X≤5) is equal to:
P(X≤5) = 0.0018+0.0137 + 0.0480 + 0.1065 + 0.1675 + 0.1982
P(X≤5) = 0.5357
