In order for the sum to be greater than 7, there are a few possible combinations which are shown below:
The probability for each individual dice to roll a certain number is:
If we want both to roll an exact number we have:
Any of the four probabilities can happen for our requirements to be met, therefore the total probability of at least one of them happening is the sum of all the probabilities:
For the sum of the dices to be not be divisible by 2, the result must be an odd number. The combinatios that could result in that are:
Which gives us a total of 18 possibilities. Since the probability of each of this happening is equal to 1/36, then the total probability is given by 18 times that, which results in the below:
Answer:
Keaton solved it right.
Step-by-step explanation:
Both students did the first step correctly, but Emily divided on the last step instead of multiplying. When there is a division on the other side of the equation, you would have to multiply the denominator on both sides. Keaton correctly multiplied the denominator of 3 on each side which gives 12 * 3 = 36.
I really hope this helps! :)
Answer:
<h2>x=68</h2>
Basic fact:
<em>angles in a triangle add up to make 180 degrees</em>
Step-by-step explanation:
we know that
72+40+x=180
112+x=180
-112
x=68
Answer:
21 (42 for original, 21 is the angle measure divided by 2)
Step-by-step explanation:
First let's start by finding the value of x.
We know that Angle BCA is equivalent to 180-8x+30 so Angle BCA = 210-8x.
Since angles in a triangle add up to 180:
4x+8+2x+2+210-8x=180
-2x=-40
x=20
Now we plug 20 in for x
2x+2=2(20)+2=42
The question asks for the angle measure to be divided by 2 so...
42/2=21
A.
$10
B.
$5 + 0.05t
(T = per text)
C.
0.10t
That’s what I got from the wording so hope that helped.
