Match the information on the left with the appropriate equation on the right.

The equation of the line passing the points (-2,3),(-3,4) is y = -x + 1 or x+y = 1

<h3>Equation of a line</h3>

A line is the shortest distance between two points. The equation of a line in slope-intercept form is expressed as;

y = mx + b

m is the slope

b is the y-intercept

Given that m=1, b=-3, the required equation will be y = x - 3 or x - y = 3

For the parameter m=1, (-1,2)

y - 2 =1(x+1)

y - 2 = x+1

y =x + 3

Hence the equation of the line for the parameters m=1, (-1,2) is y = x + 3

For the coordinates (-2,3),(-3,4)

Slope = 4-3/-3+2
Slope = -1

For the intercept;

4 =-1(-3) + b

b = 4 - 3

b = 1

Hence the equation of the line passing the points (-2,3),(-3,4) is y = -x + 1 or x+y = 1

kotykmax [81]

By verbal reasoning, the pair of words required can be obtained from the

synonyms of the given pair.

Correct response:

<u>Variable</u>; <u>supposition</u>

<h3>Analysis used for making the above selection</h3>

Prediction: A prediction is a statement indicating the result to be

expected from a trial or test, based on deductive reasoning from a

theory or hypothesis.

An explanation is a statement describing a phenomenon and is taken as

an hypothesis.

A variable is an outcome of a test or trial, or observation.

A supposition is a held notion or belief that is similar to a hypothesis.

Therefore;

Prediction is to explanation as <u>variable</u> is to <u>supposition</u>.

Bobby is testing the effectiveness of a new cough medication. There are 100 people with a cough in the study. Seventy patients r

Tresset [83]

Answer:

0.665

Step-by-step explanation:

Given: 100 people are split into two groups 70 and 30. I group is given cough syrup treatment but second group did not.

Prob for a person to be in the cough medication group = 0.70

Out of people who received medication, 34% did not have cough

Prob for a person to be in cough medication and did not have cough

= $\frac{0.70(34)}{60}=0.397$

Prob for a person to be not in cough medication and did not have cough

= $\frac{0.3(20)}{30}=0.20$

Probability for a person not to have cough

= P(M1C')+P(M2C')

where M1 = event of having medication and M2 = not having medication and C' not having cough

This is because M1 and M2 are mutually exclusive and exhaustive

SO P(C') = 0.397+0.2=0.597

Hence required prob =P(M1/C') = $\frac{0.397}{0.597}=0.665$
