"3" is the one among the following choices given in the question that is <span>the number of sides of a regular polygon if one interior angle is 60 degrees. The correct option among all the options that are given in the question is the first option or option "A". I hope the answer has actually come to your great help.</span>
Answer:
Step-by-step explanation:
cosine x²= cos x²
Rule
Given that,
The complete question gives you three options:
A) odd = made, even = missed.
B) 1 to 9 = made, 0 = missed.
C) 0 to 4 = made, 5 to 9 = missed.
You need to understand which of these options represent a 90% probability to make the throw.
Let's see the options, considering that the total number of 1-digits is 10:
a) there are 5 odd digits, therefore the probability would be 5/10 = 0.5, which is 50%. Hence, this option is not correct.
b) there are 9 digits between 1 and 9, therefore the probability would be 9/10 = 0.9, which is 90%. Hence, this option is valid.
c) There are 5 digits between 0 and 4, therefore the probability would be 5/10 = 0.5, which is 50%. Hence, this option is not correct, as option a.
Therefore, the correct answer is B)<span> 1 to 9 = made, 0 = missed.</span>
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
Let's write down the equations which we will be solving as displayed below:
Equation No. 1 -
4m + n = 6
Equation No. 2 -
3m = 2n - 13 / 2
To begin with, we will make ( n ) the subject in the first equation as displayed below:
Equation No. 1 -
4m + n = 6
n = 6 - 4m
Next, we will substitute the value of ( n ) from the first equation into the second equation and also make ( m ) the subject. Then, we will solve the equation as displayed below:
Equation No. 2 -
3m = 2n - 13 / 2
3m = 2 ( 6 - 4m ) - 13 / 2
3m = 12 - 8m - 13 / 2
3m + 8m = 12 - 13 / 2
11m = 11 / 2
m = ( 11 / 2 ) ÷ 11
m = 1 / 2
Now we will substitute the value of ( m ) from the second equation into the first equation as displayed below:
Equation No. 1 -
n = 6 - 4m
n = 6 - 4 ( 1 / 2 )
n = 6 - 2
n = 4
ANSWER:
Therefore, our answer is:
m = 1 / 2
n = 4

-3x = -3 because you would multiply one of the equations by -1 to eliminate y.
