What is the answer to this ?

Answer:

n = 9

Step-by-step explanation:

7n + 5 = 68

7n + 5 - 5 = 68 - 5

7n = 63

7n / 7 = 63 / 7

Answer:

There will be 56 possible combinations if he is allowed to choose the same topping twice.

There will be 47 if he is not allowed to choose the same topping twice.

Step-by-step explanation:

Number of ways max choose two are 45

Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of both the selection is irrelevant. You can choose the components of combos in any order;

Permutations and combinations can be mixed up. The sequence in which the chosen components are chosen is crucial in permutations, too. For instance, the configurations ab and ba are distinct in permutations but equivalent in combinations (regarded as one arrangement);

Given;

Toppings available to make an ice cream sundae = 10

The  number of ways can Max choose 2;

= 10C2

=10! / [(10-2)! X 2!]

=45

Therefore, Max can choose toppings is 45 by combination

f(x) + g(x) = (-2x + 8)+ 3x

f(x) + g(x) = -2x + 8 + 3x   Combine like terms.

f(x) + g(x) = x + 8        

f(x) + g(x) = (f+g)(x) = x + 8

(f + g)(-1) = -1 + 8

Answer: 13 1/3 Ibs

Step-by-step explanation:

Simplified that’s 13 1/3

The amount of the dog food in the bag will be 40/3 or 13.33.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

I have 20 pound bag of dog food if it is 2/3 full right now.

Then the amount of the dog food in the bag will be

⇒(2/3) x 20

⇒ 40 / 3

Answer:

$38

Step-by-step explanation:

I solved this by doing a proportion, 41.04/108 = x/100 to find the original price before the 8% tax. To solve this proportion you have to isolate the variable, so you would do the cross product and multiply (41.04 x 100) and have that equal to 108x. So then because you have 108x = 4104, isolate x by dividing by 108 and you get 38, thus $38.

You can also check your work by multiplying 38 by 0.08 to find the amount of sales tax added, and if you do this you will get the value $41.04.

A percentage is a number or ratio that represents a fraction of 100. 

If an item costs $41.04, including an 8% sales tax then the cost of the item before the tax is $37.76.

A percentage is a number or ratio that represents a fraction of 100. 

Example:

50% = 50/100 = 1/2

20% = 20/100 = 1/5

25% = 25/100 = 1/4

10% = 10/100 = 1/10

5% = 5/100 = 1/20

We have,

Cost of an item including tax = $41.04

Sales tax = 8%

8% = 8/100

The cost of the item without the sales tax:

= 41.04 - (8% of 41.04)

= 41.04 - (8/100 x 41.04)

= 41.04 - 3.2832

= 37.76

Thus,

The cost of the item before the tax is $37.76.

Answer:

P(X = 2) = 0.0486

Step-by-step explanation:

We are told that probability of selling items is 2 out of 20.

Thus, probability of success is;

p = 2/20 = 0.1

you have 4 potential customers and you want to find the probability that you are going to sell to exact 2 of these customers.

This is a binomial probability distribution problem.

Thus;

n = 4 and x = 2.

So;

P(X = 2) = C(4, 2) × 0.1^(2) × (1 - 0.1)^(4 - 2)

P(X = 2) = 6 × 0.01 × 0.81

P(X = 2) = 0.0486

Step-by-step explanation:

The probability that the card that you draw is a black 7 or a black 8 is 1/13

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

So, the probability that the card that you draw is a black 7 = 4/52

So, the probability that the card that you draw is a black 8 =  2/26

Therefore,

the probability that the card that you draw is a black 7 or a black 8 =  4/52 - 2/26 = 1/13

The poll uses voluntary response, so the results tell us little about the population of all adults.

Step-by-step explanation:

I took the test

The one which is true would be; C poll uses voluntary response, so the results tell us little about the population of all adults.

If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.

Let the sample mean given as [tex]\overline{x}[/tex] and

The sample standard deviation s, and

The sample size = n, and

The level of significance = [tex]\alpha[/tex]

About 59% of the 45,000 people responded as "Yes" to the question

The sample size is n = 45,000.

The sample proportion is p = 0.59.

The sample selected is a voluntary sample, such that the individuals provided their responses voluntarily. So, the sample is not a true representative of the population.

Thus the results tell us little about the population of all adults because of the large sample size.

The correct option is C poll uses voluntary response, so the results tell us little about the population of all adults.
