Answer:
72
Step-by-step explanation:
The correct answer is 370. A system of equations can be
used, where h represents the number
of calories in a hamburger and f represents
the number of calories in an order of fries. The equation <span> 2</span> h plus 3 f equals 1,700 represents the
fact that 2 hamburgers and 3 orders of fries contain a total of 1700 calories,
and the equation h<span> equals f
plus 50</span> represents the fact that one hamburger contains 50 more
calories than an order of fries. Substituting f plus 50 for h in
2 h plus 3 f equals 1,700 gives <span>2, parenthesis, f plus
50, close parenthesis, plus 3</span> f, equals 1,700. This equation
can be solved as follows:
2 f plus 100 plus 3 f equals 1,700
5 f plus 100 equals 1,700
5 f equals 1,600
f equals 320
<span>The
number of calories in an order of fries is 320, so the number of calories in a
hamburger is 50 more than 320, or 370.</span>
Step-by-step explanation:
Hey there!
The 1st equation is;
y= 1/2 x-8.............(i)
Comparing the equation y= mx+c. We get;
Slope (m1) = 1/2
The equation of point which moves through point (-3,-4).
(y-y1) = m2 (x-x1). {Use one-point formula to find out the equation}
(y+4) = m2 (x+3)..………(ii)
Now, we need to find m2.
So, the condition of perpendicular lines: m1*m2= -1.


Therefore, m2 = -2.
So, let's keep value of m2 in eqaution (ii).
y+4 = -2(X+3)
y+4 = -2x-6
y = -2x -10.
Therefore, the eqaution is y= -2x-10.

Answer:
Option 2) A binomial variable with 25 independent trials
Step-by-step explanation:
We are given the following in the question:
Sample size = n
R: the number of people from the sample who answer yes to the question whether they have read a novel in the past year.


Then, the random variable R follows a binomial distribution:
- There are n independent trials.
- Each trial have two results either they have read the book or they have not read the book
- Probability of success for each trial is same.

Thus, R is a binomial variable with 25 independent trials.
