Step-by-step explanation:

We have ,

n(A) = 16 n(B) = 19

We know that the number of elements in Cartesian product of two sets is ,

The price of a notebook has dropped to $3.45 today. Yesterday's price was $3.95. Find the percentage decrease. Round your answer to the nearest tenth of a percent.

Answers

10%

Step-by-step explanation:

($3.95 - $3.45)/($3.95) × 100%

= ($0.50)/($3.95) × 100%

= 50/3.95 %

= 5000/395 %

= 1000/79 %

= 12,65 % → Round to the nearest tenth

A triangle is shown
What is x?
What is y?
What is z?

Answers

Answer:

x = 44

y = 136

z = 136

Step-by-step explanation:

The angles of a triangle have to add up to 180°

54 + 82 + x = 180

136 + x = 180

x = 44

We know that y and z are vertical angles, so they have the same measurements.

Also, x and the other angle across from it are also vertical angles.

88 + 2n = 360

2n = 272

n = 136

Therefore,

x = 44

y = 136

z = 136

There are 130 people in a sport centre.
61 people use the gym.
68 people use the swimming pool.
60 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
19 people use the gym and the track.
6 people use all three facilities.
A person is selected at random.
What is the probability that this person doesn't use any facility?

Answers

The probability that this person does not make use of the facility is 7/130

How to solve for the probability

61+68+60 - 25-28-19 + 6

= 123

The total number of person in the sport center is given as 130

We have 130 - 123 = 7

This means that there are a total of 7 persons that do not make use of this facility.

Hence the probability of a person not using the facility is 7/130

Answers

Answer:-105

Step-by-step explanation:

Answer:

Ok so, let's break it down

Step-by-step explanation:

-35+(-31)

Let's ignore the parenthesis and the - symbol

35+31

That would equal 66, so now we add back the - symbol which will make it -66

So we already have -66, so now we have -66+(-39)

We do the same thing we did with -35+(-31)

So we have 66+39

That makes -105

So your answer is -105

Deion is making sandwiches for a picnic. He uses 2 slices of cheese to make each sandwich,
and he has a package of cheese with 24 slices. How many sandwiches can Deion make before
he runs out of cheese?
answer quickly please!

Answers

Answer:

12 sandwiches

Step-by-step explanation:

We know that Deion has 24 cheese slices, and uses 2 slices per sandwich, so in order to find how many sandwiches he can make, we can divide the total number of cheese slices by the number used to make a sandwich:

24 / 2 = 12

Therefore, Deion can make 12 sandwiches before he runs out of cheese.

How do you write 7 1 \12 as a whole number

Step-by-step explanation:

Write as a decimal

7 1/2 would be written as ~7.0833

Rounding a decimal to the nearest whole number

If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.

If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.

Since 0 is in the tenth’s place we round down to 7.

PLEASE HELP ME ASAP.

Answers

Step-by-step explanation:

anything whole or complete is designated as 100%.

what is x% of that whole ?

well, we need to multiply the whole with the same factor we need to multiply 100 with to get x.

100×f = x

f = x/100

whole × f = x% of the whole

so, when we are looking for 5%, what did that mean ?

it means that x = 5, and f = 5/100.

therefore, 5% of $13 is

13 × 5/100 = 65/100 = 0.65

so,

basic cost = $13

tax rate = 5%

tax amount = $0.65

and

basic cost = $13

tax amount = $0.65

total cost = 13 + 0.65 = $13.65

as 5/100 = 0.05

we have seen that the tax amount is simply $13×0.05

and when we add the tax amount to the basic cost, we need to add $13×1 (basic cost) to the $13×0.05 (tax amount), and we get as total

total cost = $13×(1+0.05) = $13×1.05 = $13.65

so, the decimal factor we can use directly without going through all the detail above is : 1.05

Answer: 8.3

Explanation:

The mean is the average of a data set; it is the number that falls directly in the middle of the data set.

The formula to find the average is: a=sum of terms/ number of terms.

Therefore, we just add up all the values in the data set and divide by how many numbers there are.

3+9+10+10+4+10+10+10/8 = 8.25. We added up all the numbers and then divided by how many numbers there were, which was 8.

8.25 rounded to the nearest tenth is 8.3.


Your answer is 8.3

Can you please help me with my homework I don’t get it.

Answers

The slope-intercept form is y = mx + b where:

m= slope
b = y-intercept (The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.)

To start with, you’ll need two ordered pairs (x,y) from the line to solve for slope.

For the first graph:
Let (x1,y1) = (0,2)
(x2,y2) = (2,4)

Substitute these values into the slope formula:

m = (y2 - y1)/(x2 - x1)

m = (4 - 2)/(2 - 0)
m = 2/2 = 1

Therefore, the slope (m) = 1.

Next, for the y-intercept, the point where it crosses the y-axis is at point (0, 2). Therefore, the y-intercept (b) = 2.


Thus, the linear equation of the first graph in slope-intercept form is: y = x + 2.


For the 2nd graph, do the same steps as we have done in the 1st graph:

Choose 2 ordered pairs:

Let (x1,y1) = (0,2) — right off the bat, this is the y-intercept.
(x2,y2) = (2,0)

Substitute these values into the slope formula:

m = (y2 - y1)/(x2 - x1)

m = (0 - 2)/(2 - 0)
m = -2/2 = -1

Therefore, the slope (m) = 1.

For the y-intercept, I noted earlier that (0,2) is the y-intercept. Hence, b = 2.

The linear equation in slope-intercept form of the 2nd graph is: y = -x + 2
