Step-by-step explanation:
The answer is option D.
1. N=x+3
S=2(x+3), or Sam=2x+6
Answer:
y=12x+22 is linear but not proportional
Step-by-step explanation:

This is a linear equation because it has an x and y within the expression without exponents or other complex operators. We can rearrange and simplify the equation into slope-intercept form.

This linear equation follows the form y=mx+b where m is the slope and b is the y-intercept. For this function, m=12 and b=22. This is not a proportional relationship because the function's y-intercept is something other than 0.
Answer:
1 ÷ 2(9 + x)
4.5 + 0.5x
Step-by-step explanation:
Given that
We write the expression i.e. half of the sum of $9 and a number
Here we need to write the two expression that is different from each other
So,
Let us assume the number be x.
Now The first equation depend on the information given will be:
= 1 ÷ 2(9 + x)
And, The second equation is
= (9 + x) ÷ 2
= 4.5 + 0.5x
Answer:
15 times
Step-by-step explanation:
To find the expected count you have to multiply the probability of the favorable event with the number of repetitions/rolls. For a fair dice, every number will have the same probability to occur. The dice have number 1 to 6 which mean there are 3 odd numbers (2, 4, 6) out of 6 possible number.
Then the probability for odd number will be: 3/6= 1/2
The expected count of odd numbers in 30 rolls will be= 1/2 * 30 =15 times.
