Total times die rolled =10+6+4+8+6+6=40
Times 3 and 6 appears
Experimental probability
P(3 or 6)
Answer: C, a set of coords is only a function if it passes the vertical line test
Step-by-step explanation:
This is essentially the vertical line test. No two sets can have the same x value because it will fail the vertical line test. In answer a, -4 correlates to two y values. It fails the line test
B easily fails the test just by visually looking at it. It fails the line test
C has different x values so this looks promising. It passes the line test
D has the number 5 correlating with multiple y values. It fails the line test
You can first set up a ratio to see how many TOTAL computers are needed for a r to 12 ratio.
(5/12) = (x/924) Now cross multiply to solve. 12x = 5(924) 12x = 4620
Divide both sides by 12. x = 385
There are a total of 385 computers needed for the school to have a 5:12 ratio.
Since the school already has 125 computers subtract 385-125 = 260. They need to purchase 260 more computers.
Answer:
the options are missing, so I looked for a similar question:
- 4 inches by 3 inches
- 3 inches by 1 inch
- 6 inches by 2 inches
the correct options are:
3 inches by 1 inch
6 inches by 2 inches
A scaled copy means that the values of rectangle A are related to the value of rectangle B by a scaling factor. In this case, the scaling factor is 3:1. This means that for every 3 inches in rectangle A, you will have 1 inch in rectangle B.
E.g. imagine that instead of making the rectangle smaller, you would make it larger. Using the same scale 3:1, rectangle B could be 30 inches by 10 inches, or 600 inches by 200 inches.
-3(-15w+2)
You have to use the distributive property to simplify this expression.
-3 times -15w is 45w.
-3 times 2 is -6.
-3(-15w+2)
45w-6 is the answer
