What is the probability of landing on A then a C?* First Spin Second Spir С C E A B A DC
Answer:
Probability of landing on A: 25% chance
Probability of landing on C: 37.5% chance
Step-by-step explanation:
A. There are 2 A’s out of 8 letters which gives us a fraction of 2/8.
2/8 = 1/4 = 0.25 = 25%
C. There are 3 C’s out of 8 letters which gives us a fraction of 3/8.
3/8 = 0.375 = 37.5%
Hopefully this helped, good luck!

Janet can make 1/2 of a necklace in 20 minutes. At this rate, how many necklaces can Janet make in 2 hours?
Answer:
3 necklaces
Step-by-step explanation:
2 hours = 120 minutes
1 necklace in 40 minutes
120/40 = 3
3 necklaces
Answer:
3 necklaces
Step-by-step explanation:
2 hours needs to be in the same units as the 20 minutes
2 hours = 2 * 60 minute = 120 minutes
Now we can use ratios to solve
1/2 necklace x necklaces
-------------------- = ----------------
20 minutes 120 minutes
Using cross products
1/2 * 120 = 20x
60 = 20x
Divide by 20
60/20 = 20x/20
3= x

Which set of ordered pairs does not represent a function?
Answer:
D
Step-by-step explanation:
(0, 0) (0, 1) (1, 2) (1, 3)
For it to be a function each x value should have one y value.
There are two 0's for x and two 1's for x. This is how you can tell it's not a function.

Measure of missing angle
Answer:
44 degrees.
Step-by-step explanation:
Since angle A is 46 degrees, and angle C is 90 degrees (because of the right angle) you add 46 and 90 (you get 136) then subtract it from 180 (since every triangle equals 180 degrees) which gets you to 44 degrees.
Answer:
224
Step-by-step explanation:
360-46-90=224

Name the following geometric image
Answer:
Ray
Step-by-step explanation:
A ray is a line that has one definite start point and then continues in one direction forever. Rays are commonly combined to create angles. In an angle, each ray begins at the vertex, the definite starting point, and then goes straight in one direction. In this question, the image would be called ray LM.
Evaluate the expression for x = 29.
