<span>y = -1/2x +2 1/2</span>
General equation;
y = mx + c
Calculating the slope;
Change in y/ (change in x) = gradient m
(2-1)/(1-3) = - 1/2
Replacing m gives;
y= -1/2x + c
Calculating the value of c
take point (1,2) above and replace y with 2 and x with 1
2=-1/2 *1 +c
c = 2 1/2
Equation then is
y = -1/2x +2 1/2
Multiplying fractions by whole numbers:
1. You have to convert the whole number into an improper fraction.
2. You then multiply the fractions straight across.
Ex: 2/3 × 6 =2/3 × 6/1 = 2×6/3×1= 12/3= 4
Explanation:
Draw a dot 2 units above each dot shown on the graph. Connect the dots in the same way they are connected here.
f(x)+2 simply translates the curve up 2 units.
Answer: a = 110ᴼ
Step-by-step explanation:
The angles on each line of the figure add to equal 180ᴼ
180 - 70 = 110
a = 110ᴼ
b and 70ᴼ are vertical angles, so their measures are congruent.
b = 70ᴼ
180 - 70 = 110
c = 110ᴼ
Answer:
d) 1
Step-by-step explanation:
The variance of standard normal distribution is simply put as 1.
If you take it a bit further, even though not asked, the mean of a standard normal distribution is 0.
Therefore, the conclusion is that, the variance of a standard normal distribution is 1, while the mean of the same standard normal distribution is 0
