Which is the formula for slope of a line.

PilotLPTM [1.2K]

If the line passes through the points $A(x_1,y_1)$ and $B(x_2,y_2),$ then the slope of the line can be determined as

$m=\dfrac{y_2-y_1}{x_2-x_1}.$

Then the equation of the line is

$y=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)+y_1.$

Each time Caroline goes shopping she decides whether or not to buy fruit.

DiKsa [7]

Let event A = Caroline buys fruit, event B = Caroline buys CD, Ac and Bc are complementary events.

Events AB, ABc, AcB and AcBc are jointly exhaustive and disjoint, hence P(AB) + P(ABc) + P(AcB) +P(AcBc) =1.

Events A and B independent, hence Ac and Bc independent too and probability P(AcBc) = P(Ac)*P(Bc) = (1 - P(A))(1-P(B)) = 0.6*0.4 = 0.24.

Required probability P(AB + ABc + AcB ) = P(AB) + P(ABc) + P(AcB) = 1- P(AcBc) = 1 - 0.24 = 0.76.

Answer: Probability that Caroline buys fruit, a CD or both is 0.76.

Smokers: Out of 780 smokers, 376 have been divorced.

beks73 [17]

For statictics of Out of 780 smokers, 376 have been divorced, Non-smokers: Out of 2855 non-smokers, 902 have been divorced, the 95% confidence interval for smokers and non-smokers is mathematically given as

95% confidence interval = (0.5352, 0.4462)
95% confidence interval = (0.3424, 0.2894)
53% increased risk of divorce for smokers.

<h3>What is the 95% confidence interval for smokers and non-smokers?</h3>

Generally, the equation for the Confidence interval is mathematically given as

p ± Z/2[p(1-p)]/n

Where

Z1/2=1-(0.05/2)

Z1/2=0.975

Read z table we have

Z score= 1.96

Hence

0.4907 ± 1.96 (0.4907)(1-0.4907)/485

0.4907±0.0445

Therefore

95% confidence interval = (0.5352, 0.4462)

Z1/2 = 1- (0.05/2)

Z1/2 = 0.975

Z score= 1.96

0.3159 ± 1.96 (0.3159)(1-0.3159)/1184

0.3159±0.0265

Thereofore

95% confidence interval = (0.3424, 0.2894)

In conclusion, The 95% confidence interval helps us read that 53% increased risk of divorce for smokers.
