If a certain medicine cures 90% of the people who take it, what is the probability that if 9 people take the medicine that 6 will be cured?A) 0.01
B) 0.02
C) 0.04
D) 0.33

Answers

Answer 1

Answer: This is an example of binomial distribution probability. The probability that a person gets cured by the medicine (p) is 90% or 0.9. The probability that a person does not get cured by the medicine (q) is 100 - 90 = 10% = 0.1. The probability of a binomial distribution is given by nCx (p)^x (q)^(n - x); where n is the sample size, x is the number of success, p is the probability of success, and q is the probability of failure. Therefore, the probability that out of 9 people that takes the medicine, 6 will be cured is given by 9C6 (0.9)^6 (0.1)^3 = 84 x 0.531441 x 0.001 = 0.0446. Therefore, option C (0.04) is the correct answer.

The calorie count of a serving of food can be computed based on its composition of carbohydrate, fat, and protein. The calorie count for a serving of food can be computed using the formula C=4h+9f+4p, where his theof grams of carbohydrate contained in the serving, is the number of grams of fat contained in the serving, and is the number of grams of protein contained in the serving

A serving of a certain type of but contains 12 grams of fat, 6 grams of carbohydrate, and 5 grams of protein. How many calones are in this serving of ruts?

There are calories [___] in this serving of nuts

Answers

Answer:

152 calories

Step-by-step explanation:

The calories count, composition of carbohydrates, fat and protein are related by;

C = 4h + 9f + 4p

where C, h, f, and p have there given meaning.

Given that the serving of a type of nut contains; f = 12 grams, h = 6 grams and p = 5 grams, then;

C = 4(6) + 9(12) + 4(5)

= 24 + 108 + 20

= 152

C = 152 calories

Therefore, there are 152 calories in the serving of the certain type of nut.

Final answer:

The serving of nuts contains 152 calories.

Explanation:

To compute the calorie count for a serving of food, you can use the formula C = 4h + 9f + 4p, where C is the calorie count, h is the grams of carbohydrate, f is the grams of fat, and p is the grams of protein. In this case, the serving of nuts contains 12 grams of fat, 6 grams of carbohydrate, and 5 grams of protein. Plugging these values into the formula gives:

C = 4(6) + 9(12) + 4(5)

C = 24 + 108 + 20

C = 152

Therefore, there are 152 calories in this serving of nuts.

A small town surveys 250 adults, 180 of which are parents, about whether or not a park should be expanded. The results showed that 150 of the adults with children and 40 of those without thought the park should be expanded. Use this information to complete the two-way table below.

The surveyed parents for the favor of park extension, two way table is way or representation of data. and The two way table is completed as,

yes no

parents 150 | 30

not parents 40 | 30

The two way table shown in the table is attached below.

What is two way table?

Two way table is a way of representation of data to better understand it.

Given information-

Total number of adults took the survey is 250.

Total number of parents took the survey is 180.

150 of the adults with children and 40 of those without thought the park should be expanded.

Suppose the number of adults who are not the parents and took the survey is $x$ .

As the total number of adults took the survey is 250 in which the number of parents took the survey is 180. Thus the number of adults who are not the parents and took the survey is,

$x=250-180\nx=70$

Suppose the parents who does not thing that the park should be expanded is $y$ .

There is total 180 parents. As 150 of the adults with children thought the park should be expanded. Thus, the parents who does not thing that the park should be expanded is,

$y=180-150\ny=30$

Form the 70 adults who are not parents things that park should be expanded is 40, hence the adults who are not parents does not thing the park should be expanded is (70-40) which is 30.

Hence the two way table is completed as,

yes no

parents 150 | 30

not parents 40 | 30

The two way table shown in the table is attached below.

250 adults and 180 of which are parents, so 250 -180 = 70 are not parents. The results showed that 150 of the adults with children and 40 of those without thought the park should be expanded. So there are 180 – 150 = 30 parents who answered no. and 70 – 40 = 30 not parents who answered no.

What is the degree of the monomial 7x^8

Answers

The given monomial is

$7x^8$

And degree is the highest exponent of the constant .

For e.g.

Degree of $x^5$ is 5 since 5 is the exponent of x here. And in the given question, Here the constant is x.

And the exponent of x is 8 .

Therefore the degree of the given monominal is 8 .

it is to the power of 8

To the nearest tenth, what is the length of the hypotenuse of an isosceles right triangle with a leg of 7 3 inches? A) 15.7inches
B) 16.2 inches
C) 17.1 inches
D) 18.5 inches

Answers

Answer:

the answer is the option C

$17.1\ in$

Step-by-step explanation:

we know that

An isosceles right triangle has two equal legs

Let

x------> the length side of the hypotenuse

y-----> the length side of the leg

Applying the Pythagoras theorem

$x^(2) =y^(2)+y^(2)$

$x^(2) =2y^(2)$

In this problem we have

$y=7√(3)\ in$

Substitute and solve for x

$x^(2) =2(7√(3))^(2)$

$x=17.1\ in$

What is the tenth term in the sequence 5,8,11,14...?

A. 29

B.32

C. 35

D. 38

Answers

cause 5+3+8, 8+3=11 11+3=14, so 14+3=17 17+3=20, 20+3=23 23+3=26 26+3=29 29+3=32
so its 5, 8, 11, 14, 17, 20, 23, 26, 29, 32
so the answer is 32

Since the sequence is adding 3 to each number, 5+3=8, 8+3=11, 11+3=14, 14+3=17, 17+3=20, 20+3=23, 23+3=26, 26+3=29, 29+3=32, 32 is the answer since it is the tenth term in sequence.
