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') = $\frac{0.397}{0.597}=0.665$

Write the equation of the line? write the equation in standard form.

vlabodo [156]

Answer: y= 1

This because the line has no slope so the equation really looks like this if we were to follow the y=mx+b format.

y=mx+b
y= 0x + b

because the number "0" multiplied by any value is still zero we can exlude that from the final equation of the line. In this case since m=0, the line is y=b.

b is the y intercept, or the value of y when x = 0.

So, because y=1 when x is 0, "b"= 1

y=b
y=1

Any questions?
