Answer:
y = -x +4
Step-by-step explanation:
The y-intercept of the line is at +4, so the only viable choice is the last choice.
___
Each of the equations is shown in slope-intercept form:
y = mx + b
where b is the y-intercept, the y-value when x=0. The graph shows that as point (0, 4). So, the equation you're looking for is ...
y = (some x-term) +4
If you want to spend more brain power on the problem, you can compute the slope of the line as ...
m = ∆y/∆x = (1-4)/(3-0) = -3/3 = -1
Now, you know for sure the equation of the line is ...
y = -x +4
The value of is 1°
Explanation:
The expression is
Now, we shall determine the value of .
Multiplying both sides by , we get,
Simplifying, we get,
Substituting the value of , we get,
Rounding the value of to the nearest degree, we get,
Hence, the value of is 1°
Add up the number of students within the random sample data:
32+26+28+22 = 108
We can then use proportional fractions / cross-multiply to answer the question.
In a sample size of 108 students, 32 of them preferred Movie A.
There are 900 students in total.
32*900 = 28800
108*x = 108x
108x = 28800
x = or
In decimal form that is approximately 266.667 and round that to the nearest whole number, you get 267 students who would prefer Movie A.
Im pretty sure i can help you out on this one
If 3/8 of the recipe is going to be made, then u will need 3/8 of the sugar as well
3/8 of 3 1/4 cups would be needed
3/8 * 3 1/4 =
3/8 * 13/4 =
39 / 32 =
1 7/32 cups of sugar <=
