Answer:
x = 3
Step-by-step explanation:
I'm not exactly sure of what you mean by property but I think it might be associative property of multiplication?
But to solve for x you would subtract 6 from 18 which gives your 12. Then you divide by 4 to get the x alone and 12/4 is 3.

There are six checkout tills at a small supermarket. Two of the tills have comfy seats. What is the probability an employee will get a till with a comfy seat?
Give your answer as a fraction
Please can someone help thank you very much :)
Answers
Answer:
1/3
Step-by-step explanation:
2/6 means that 2 out of the 6 tills have comfy seats. 2/6 simplified is 1/3
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The total amount of tilts is 6
The amount of tilts with comfortable seats is 2
So there are two tilts with comfortable seats out of six tilts that are in the supermarket
Now write it as fraction:
[tex]\frac{2}{6}[/tex] = [tex]\frac{2*1}{2*3}[/tex] (alternatively 2/6)
Here we get the probability
// divide numerator and denominator by 2
[tex]\frac{2*1}{2*3}[/tex] = [tex]\frac{1}{3}[/tex] (alternatively 1/3)

Answers
Alright, sorry for possibly wasting the answer, but its either D or B. i think its D, because its a bisector of the line segment, but B reads that it IS perpendicular, but on points not the line. You can rule out which one of the two it is, i would suggest asking a teacher for help or waiting for a better and more reliable answer.

A credit card company wanted to estimate the proportion of its customers who pay their credit card minimum balance on time. The company sampled 500 records and constructed a confidence interval for the true proportion of customers who pay their credit card minimum balance on time. The resulting 95 percent confidence interval was (0.765, 0.835). Which of the following is a true statement regarding the value of the point estimate and margin of error of the percentage of customers who pay their credit card minimum balance on time?
a. The point estimate is 0.765 and the margin of error is 0.07.
b. The point estimate is 0.765 and the margin of error is 0.835.
c. The point estimate is 0.80 and the margin of error is 0.035.
d. The point estimate is 0.80 and the margin of error is 0.07.
e. The point estimate could be any number within the interval and the margin of error is 0.035.
Answers
Answer: c. The point estimate is 0.80 and the margin of error is 0.035.
Step-by-step explanation:
Given: The 95 percent confidence interval was (0.765, 0.835).
Confidence interval = Point estimate ± Margin of error.
I.e. Point estimate + Margin of error = 0.835 (i)
Point estimate - Margin of error = 0.765 (ii)
Add (i) and (ii), we get
2 (Point estimate)= 1.60
⇒ Point estimate = 0.80
Put this in (i), we get
0.80+Margin of error = 0.835
⇒ Margin of error = 0.835 -0.80
⇒ Margin of error = 0.035
Hence, the correct statement is:
c. The point estimate is 0.80 and the margin of error is 0.035.

Which boxes have a volume of 120 cubic feet? Box A: length of 5 ft, width of 4 ft, height of 6 ft Box B: length of 7 ft, width of 7 ft, height of 6 ft Box C: length of 3 ft, width of 6 ft, height of 4 ft Box D: length of 10 ft, width of 3 ft, height of 4 ft
Answers
Answer:
Boxes A and D have a volume of 120 cubit feet.
Step-by-step explanation:
First, we just have to find the volume for each box so we do...
The volume of box A is:
(Length) x (Width) x (Height) = 5 ft x 4ft x 6ft = 120 [tex]ft^{3}[/tex]
The volume of box B is:
(Length) x (Width) x (Height) = 7ft x 7ft x 6ft = 294 [tex]ft^{3}[/tex]
The volume of box C is:
(Length) x (Width) x (Height) = 3ft x 6ft x 4ft = 72 [tex]ft^{3}[/tex]
The volume of box D is:
(Length) x (Width) x (Height) = 10ft x 3ft x 4ft = 120 [tex]ft^{3}[/tex]
Now we can see that boxes A and D have a volume of 120 cubit feet.

f(x)=−x 2 −4x−19 find f(-9)
Answers
Answer:
64
Step-by-step explanation:
The value of the function f(x) = x² −4x−19 at the value x = -9 will be 98.
What is a function?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given function is f(x) = x² −4x−19. The value of the function at f(-9) will be calculated as:-
f(x) = x² −4x−19
f(-9) = ( -9 )² - ( 4 x --9 ) - 19
f(-9) = 81 + 36 - 19
f(-9) = 98
Therefore, the value of the function f(x) = x² −4x−19 at the value x = -9 will be 98.
