Answer:
mean=14, variance=9.1
Step-by-step explanation:
for binomial distribution
n=number of outcomes
p=probability of succcess
q=probability of faliure
p+q=1
any probability given is always 'p'
mean=np
n=40
p=0.35
mean=40*0.35
mean=14
variance=npq
p+q=1
q=1-p
q=1-0.35
q=0.65
variance=40*0.35*0.65
variance=9.1
Answer:
2/x + 3/y = 5
Step-by-step explanation:
A linear equation refers to any equation that can be written in the form;
ax+b=0 or y - mx -c = 0
The graph of a linear equation will always be a straight line; Vertical, horizontal or with a given degree of steepness (slope).
All the equations given are linear, except the last equation;
2/x + 3/y = 5. The exponents of the variables x and y is not 1 hence the equation is non-linear. Find the graph attached;
1,000,000, because its the 1st 7 digit number and it happens to be even
1/10÷2/3=KCF (keep,change,flip)
1/10×3/2=3/20 cups
0.15=15%=3/20 as decimal*percent
