Answer:
a. -⅓
b. 3
c. y = 3x - 10
Step-by-step explanation:
a. Gradient of line AB:
A(1, 3), B(7, 1)
Gradient (m) = -⅓
b. The of the line that is perpendicular to line AB would be the negative reciprocal of the gradient of line AB.
Thus, the negative reciprocal of -⅓ = 3
Gradient of the line perpendicular to line AB = 3
c. Equation of the line that passes through (4, 2) and is perpendicular to line AB:
We can write the equation using the point-slope form equation, y - b = m(x - a), where,
(a, b) represents a point on the line, and,
m = gradient/slope
We know that the gradient/slope (m) = 3
Also, a point, (a, b) = (4, 2).
Therefore, substitute a = 4, b = 2, and m = 3 into y - b = m(x - a)
Thus:
y - 2 = 3(x - 4)
y - 2 = 3x - 12
Add 2 to both sides
y = 3x - 12 + 2
y = 3x - 10
Answer:
25
Step-by-step explanation:
<u>Formula</u>
Where M meters of granola makes B granola bars.
<u>Given:</u>
M = 2.5 meters
Now substitute that value in the formula and calculate.
Therefore, 2.5 meters of granola makes 25 granola bars.
B = 25
Answer:
0.044
Step-by-step explanation:
n=9,p=0.9, x =6.
Apply Binomial probability we get
Sum P(x)=C(n,x) for x=6
Putting in the formula ,
we get
P(x) = C(9,6)
84 X 0.531441 X 0.001
= 0.044
