Answer:
12.3
Step-by-step explanation:
subtract(its me again)
Given:
Bl parallel to RA.
To find:
The value of x.
Solution:
In triangle ATR and ITB,
[Common angles]
[Corresponding angle]
[AA property of similarity]
We know that the corresponding sides of a similar triangle are proportional. So,
On cross multiplication, we get
Therefore, the correct option is C.
Since the spinner is labelled A, B, C, D, there are four possible landing for the spinner.
Thus, the sample space is {A, B, C,D}.
Therefore, the number of <span>elements in the sample space for spinning a spinner labeled A, B, C, D</span> is 4.
Answer:
6/21
Step-by-step explanation:
1. First, check all the possible combinations for a pair of dice:
1-1
1-2 2-2
1-3 2-3 3-3
1-4 2-4 3-4 4-4
1-5 2-5 3-5 4-5 5-5
1-6 2-6 3-6 4-6 5-6 6-6
(Those are the numbers of the dice, separated by hyphons.)
2. Next, find out the products, since that is the info we need to go off of.
1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
(those are all the products based on the same chart we saw above.)
3. Now, let's calculate the probability.
- Find the amount of prime numbers. (1, 2, 3, 5) Looks like there are four total.
- Find the amount of numbers that end in a five. (15, 25) There are two. I've skipped 5 because that is already on the list.
- Find the total amount of numbers. There are 21 in our case.
4. There are 6 numbers that will satisfy our needs. (prime or ending in 5)
There are 21 total.
6/21
If you need decimal form, there is a
0.2857 chance.
Hope this helped.
Count the difference of the x values between the two points (the run of the slope) and the difference of the y values between the two points (the rise of the slope). That would get you the rate of change, or slope, of the line.
