Answer:
The euation of the linear function is:
- y = -1
Step-by-step explanation:
As the function has the values
- at x = 5, f(5) = -1
- at x = 0, f(0) = -1
Thus, the two points are:
- (5, -1)
- (0, -1)
Finding the slope between (5, -1) and (0, -1)
We know that the slope-intercept form of the line equation is
y=mx+b
where m is the slope and b is the y-intercept
We also know that the y-intercept can be computed by setting x=0 and finding the corresponding value of y.
so at x = 0, y = -1
Thus, the y-intercept 'b' = -1
Now, substituting m = 0 and b = -1 in the slope-intercept form of the line equation
y = mx+b
y = 0x + -1
y = -1
Therefore, the euation of the linear function is:
- y = -1
check the picture below.
so, when we have a line from a 90° angle running perpendicular to the opposite side, like in this case, we end up with three similar triangles, a large one containing the other two, a medium and a small one.
now, using the sides proportions as you see there, of the small and large one, we get that much.
Using the probability concept, it is found that since the number of red sweets would be a decimal number, the probability cannot be
Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
In this problem:
- In total, there are 8 + n sweets in the bag.
- Of those, n are red.
The probability of red is:
Supposing, we solve for n:
10n = 7n + 56
3n = 56
n = 56 / 3
n = 18.67
Since the number of red sweets would be a decimal number, the probability cannot be 7 / 10
