In a large population, about 10% of people do not like the taste of cilantro, an herb used in cooking. A researcher takes a rand
bogdanovich [222]

Answer:

0.0019390

Step-by-step explanation:

10% of people do not like the taste of cilantro

A researcher takes a random sample of 15 people and surveys whether they like cilantro

Use the binomial distribution to compute the probability that exactly 6 of the people in the sample do not like cilantro.

Probability of success = 0.10 = p

Probability of failure = 0.9 =q

n = 15

r = 6

Formula : P(X=r)=^nC_rp^r q^{n-r}

P(X=6)=^{15}C_6 (0.1)^6 (0.9)^{15-6}

P(X=6)=\frac{15!}{6!(15-6)!} (0.1)^6 (0.9)^{15-6}

P(X=6)=0.0019390

Hence  the probability that exactly 6 of the people in the sample do not like cilantro is 0.0019390

The entrance fee to a local waterpark is $34 per person. At the waterpark, you can rent a raft for $1.50 per hour. Which express
Tcecarenko [31]
Algebraic Equation:

The entrance fee to enter the park is fixed and the amount of hours Leah will spend at the park is a variable.

We need to add the fixed and variable amounts.

34 + h

Because we don’t know how long Leah will spend on the raft we have to multiply h by the rate per hour for a raft.

34 + 1.50h

Therefore, Leah’s cost is 34 + 1.50h
