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](https://tex.z-dn.net/?f=%5Cfrac%7B0.70%2834%29%7D%7B60%7D%3D0.397)
Prob for a person to be not in cough medication and did not have cough
=![\frac{0.3(20)}{30}=0.20](https://tex.z-dn.net/?f=%5Cfrac%7B0.3%2820%29%7D%7B30%7D%3D0.20)
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](https://tex.z-dn.net/?f=%5Cfrac%7B0.397%7D%7B0.597%7D%3D0.665)
Answer:
Step-by-step explanation:
soulution:
given, 2x +2x = 16 <em>-</em> <em>2x</em> + 3y = 14
2x <em>+ 2x</em> = <em>-2y </em>+3y = 14 -16
4x = y = -2
y = 4x = -2
y = x = 4/-2
x = y = <u><em>-2 ans</em></u>
Consecutive integers are integers that follow one another. For example, 2,3,4,5,etc.... are consecutive integers
So algebraically, consecutive integers follow the form x, x+1, x+2, etc...
Since the sum of two consecutive integers is 239, this means:
x%2Bx%2B1=239
2x%2B1=239 Combine like terms on the left side
2x=239-1Subtract 1 from both sides
2x=238 Combine like terms on the right side
x=%28238%29%2F%282%29 Divide both sides by 2 to isolate x
x=119 Divide
So our first number is x=119
So to find the next number, simply add 1 to it to get 119%2B1=120
Answer: So our two page numbers are 119 and 120
Answer:314

Answer:
<em>Option C.</em>
Step-by-step explanation:
If you subtract each value from the next one, you see the differences are different. Therefore, it is not linear. Now divide each value by the previous value. You get 1.7 each time.
Answer: Option C.
