Answer:
-5x + 0y = -11
The y terms are eliminated
Step-by-step explanation:
- 4x – 2y = -2
X - 2y = 9
We want to subtract the second equation from the first
Distribute a minus sign to all the terms in the second equation
- 4x – 2y = -2
X - 2y = 9
= (-5x + 0y = -11)
Answer:
14.76 cm
Step-by-step explanation:
Use the pythagorean theorem:
a² + b² = c²
Plug in the side lengths and solve for c:
7² + 13² = c²
49 + 169 = c²
218 = c²
14.76 = c
So, the hypotenuse is approximately 14.76 cm
13,501 rounded to the nearest 10,000 is 10,000.
There are 3 vowels out of 11 letters in the word CANDLESTICK.
Probability (vowel) = 3/11
P( N or S) = 2/11 ( as there is 1 S and 1 N in the word)
P(not C) = 1 - P(picking a C) = 1 - 2/11 = 9/11 (note there are 2 C's in the word)
Answer:
1-
P(X=1) = 1/36
P(X=2) = 3/36 = 1/12
P(X=3) = 5/36
P(X=4) = 7/36
P(X=5) = 9/36 = ¼
P(X=6) = 11/36
2-
7/36
Step-by-step explanation:

Attached, you will find a table with the possible values of X.
(See table attached)
As we can see, there are 36 entries so,
<em>P(X=1) = 1/36
</em>
<em>
</em>
<em>P(X=2) = 3/36 = 1/12
</em>
<em>
</em>
<em>P(X=3) = 5/36
</em>
<em>
</em>
<em>P(X=4) = 7/36
</em>
<em>
</em>
<em>P(X=5) = 9/36 = ¼
</em>
<em>
</em>
<em>P(X=6) = 11/36
</em>
2-
It can be noticed that the only possible value of X which is divisible by 4 is 4 and there are 7 entries in the table, so
P(X divisible by 4) = P(X=4) = 7/36
