Find the measures of the 3 angles of a triangle if the sum of the measure of
the first angle (X) and the measure of the second angle (Y) equals the
measure of the third angle (2), and if two times the measure of the first angle
is 20 degrees more than the measure of the third angle.

Answers

Answer 1

Answer:

x+y+z=180

Since y+z=5x, x+5x=180, so x=30

So,

30+y+z=180

y+z=150

Since z=y+24, y+y+24=150

2y=126

y=63

30+63+z=180

z=87

So x=30, y=63, z=87

There are ten toppings available to make an ice
cream sundae. How many ways can Max choose
two?

Answers

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

What are combinations?

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

what is the value of f(g(-3)?

Answers

Answer:

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

If an items costs $41.04, including an 8% sales tax, what was the cost of
the item before taxes?

Answers

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.

What is a percentage?

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.

Suppose that you draw one card from a well-shuffled deck of 52 playing cards. What is the probability that the card that you draw is a black 7 or a black 8

Answers

4/52 - 2/26 ANSER 1/13

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

What is the probability?

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

Answer:

Step-by-step explanation:

It does have a proportional relationship because if you try to find the relationship between the first two inputs and outputs, you can find that it is 21 (1 to 21, 21 divided by 1 would be 21) then if you use that relationship with the other numbers (times 21) you would get the same answer. For example in the second one, the two numbers are 2 and 42, 2 times 21 would equal 42. The next one would be 3 times 21 to equal 63 and etc.

A) The sample is too small to draw any conclusion.
B) About 59% of people in the US regularly read nonfiction novels.
C) The poll uses voluntary response, so the results tell us little about the population of all adults.
D) The poll uses a convenience sample, so the results tell us little about the population of all adults.
E) The poll suffers from nonresponse bias, so the results tell us little about the population of all adults.

How to calculate confidence interval for population mean for small sample?

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.

You are a salesperson and your provability of selling items is 2 out of 20. (probability of success). if you have 4 potential customers, what is the probability that you are going to sell to exact 2 of these customers

Answers

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
