If the probability that Carson will win a basketball game is 4/9. If he plays 180 games, how many can you expect him to win?
Answers
20 times 4 is 80
There u go it’s 80
4/9 = x/180

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15
Rebecca baked 100 cookies for the state fair. Sixty were oatmeal, 20 were lemon, and 20 were chocolate. What percentage of cookies were NOToatmeal?
(Explain for brainlist)
Answers
Answer:
40%
Step-by-step explanation:
If 60 out of 100 were oatmeal, 60% would be oatmeal.
20 lemon + 20 chocolate = 40
40 out of 100 is 40%
To confirm add 60 and 40;
60+40=100
Answer: 40% were NOT oatmeal. ( i think)
Step-by-step explanation:
Sense there is 100, that makes it easy.
60% is oatmeal
20% is lemon
20% is chocolate
20 + 20 = 40
So its 40% were NOT oatmeal

Employees at a company are given £1,400 to spend on items for the office.
They decide to buy a coffee machine and as many bean bags as possible.
Bean bags cost £45 with an offer of "Buy at least 10 get 10% off the price."
The coffee machine costs £320.
How much will they have left over from the £1,400?
Answers
9514 1404 393
Answer:
£27
Step-by-step explanation:
If we assume that more than 10 bean bags will be purchased, their individual cost will be £45 - 10%×£45 = £40.50. Then the total cost of n beanbags and a coffee machine will satisfy the inequality ...
£40.50n +£320 ≤ £1400
40.50n ≤ 1080
n ≤ 26 2/3 . . . . . . . 26 is more than 10, so the discount will be applied
Only an integer number of beanbags can be purchased, so the purchase of 26 beanbags and the coffee machine will leave a left-over amount of ...
£1400 -(320 +26×40.50) = £1400 -1373 = £27
The employees will have £27 left over.
Answer:
The answer is £27.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Data was collected on the amount of time that a random sample of 8 students spent studying for a test and the grades they earned on the test. A scatter plot and line of fit were created for the data.
scatter plot titled students' data, with points plotted at 1 comma 80, 2 comma 70, 2 comma 80, 2 comma 90, 3 comma 80, 3 comma 100, 4 comma 90, and 4 comma 98, and a line of fit drawn passing through the points 0 comma 70 and 1 comma 75
Find the y-intercept of the line of fit and explain its meaning in the context of the data.
80; a student who studies for 0 hours is predicted to earn 80% on the test
70; a student who studies for 0 hours is predicted to earn 70% on the test
10; for each additional hour a student studies, their grade is predicted to increase by 10% on the test
5; for each additional hour a student studies, their grade is predicted to increase by 5% on the test
Answers
Answer:
Step-by-step explanation:
The y-intercept of the line of fit is 70, which means that a student who does not study at all (0 hours) is predicted to earn a grade of 70%. In other words, the line of fit starts at the point (0,70), indicating that even if a student does not study at all, they can still earn a grade of 70% on the test. However, it should be noted that this prediction may not always hold true for all students and situations. The y-intercept provides a useful reference point for interpreting the rest of the data, and helps to establish a baseline for the relationship between study time and test grades.

I think that you would divide all the euros by 1.35 to get the pounds
if thats right then the answer should be £2504.07407408
Step-by-step explanation:
i did this by first getting the hotel price (125 euros per night) and timesing that by 14 as they stay for 14 nights, this gives you 1750
then i converted 1750 to pounds by dividing 1750 by 1.35 to get £1296.2962963
next i did the wifi price (6 x 13 = 78, 78 divided by 1.35 = £57.7777777778)
after that i added those two prices together to get £1354.07407408
the final step was to add £1150 so i got £2504.07407408, and that hopefully should be the answer !
hope this works :)

(05.01)A scale drawing of a kitchen is shown below. The scale is 1 : 20.
A rectangle is shown. The length of the rectangle is labeled 4 inches. The width of the rectangle is labeled 5 inches.
Show your work to determine the area of the room in square feet.
Answers
Answer:
the room will be 80 inches by 100 inches
( 1 inch ----> 20 inches
so 4 inches ----> 80 inches )
or
6 2/3 ft by 8 1/3 ft
The area of the given room is 166 2/3 ft².
What is a scale drawing?A scale drawing is a reduced form in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension.
The area of the room can be calculated as;
The length of the room = 20 x 4 = 80 inches
The width of the room = 20 x 5 = 100 inches.
Now, 1 inch = 1/12 foot
80 inches / 12 = 6 2/3 ft
100 / 12 = 8 1/3 ft
The Area = 6 2/3 x 8 1/3
The Area = 25/3 x 20/3
The Area = 500 / 3
The Area = 166 2/3 ft²
Therefore, The area of the given room is 166 2/3 ft².

Xavier starts with the integer -10 and multiplies it by a negative integer. Mark the statements below as true or false. If false, explain
why to the right of the statement.
a. The resulting product cannot be greater than-10.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
b. The resulting product must be greater than 0.
c. The resulting product cannot be less than 10.
Answers
Answer:
a. The resulting product cannot be greater than-10. (False)
b. The resulting product must be greater than 0. (True)
c. The resulting product cannot be less than 10. (True)
Step-by-step explanation:
Explaining Statement (a):
The integer that is given is -10,
Let it will b multiplied with another negative integers let say (-1). Starting with the smallest one in order to clarify all statement.
So, if the resultant product is represented by x, So:
x = (-10)(-1)
Using the sign Multiplication rule which is {(-)*(-)} = +
x = 10
While looking at the result It is greater than -10 because 10 is greater than -10 (So, First Statement is False)\Similarly, the resulting product is greater than 0 because 10 is greater than 0 (So, 2nd statement is true)At the end, the minimum integer choose to multiply with the -10 will be -1. It neither be -0.5 because -0.5 is not an integer. Hence answer will never ever be less than 10. (Last statement is True)
