The Venn diagram which represents the distribution of the participant in the drug trial is attached below. The Number of participants in the drug trial that has anxiety is 370

We can find the number of participants who has dizziness(D). Fatigue(F) and anxiety(A) can be calculated thus :

n(D) = n(D only) + (DnF only) + (DnA only) + (DnAnF)

271 = 36 + 86 + 23 + x

271 = 145 + x

x = 271 - 145

x = 126

n(DnAnF) = 126

Number who has atleast one of the three side effects can be expressed thus :

n(A only) + n(F only) + n(D only) + (DnF only) + (DnA only) + (DnAnF) + n(FnA only) = 585

36 + 23 + 62 + 86 + 126 + 93 + n(FnA) only = 585

n(FnA only) = 585 - 426 = 159

Number of participants who has anxiety can be calculated thus :

n(DnAnF) + (DnA only) + n(FnA only) + n(A only)

126 + 23 + 159 + 62 = 370 participants

Therefore, 370 of the total participants has Anxiety.

What is the solution for C when 10 C minus f equals -13 + c d

andreyandreev [35.5K]

Answer:

C would be equal to (f - 13)/(10 - d)

Step-by-step explanation:

In order to find this, you must manipulate the equation so that the left side has every term with a c in it. Then you can isolate it by dividing and find what it is equal to.

10c - f = -13 + cd -----> Add f to both sides

10c = f - 13 + cd -----> Subtract cd from both sides

10c - cd = f - 13 ------> Pull out c

c(10 - d) = f - 13 -----> Divide by (10 - d)

c = (f - 13)/(10 - d)

How do you find an equivalent ratio?

Nezavi [6.7K]

It can be written two ways; for example, 1:10 or 1/10. Equivalent ratios are two ratios that express the same relationship between numbers. You can create equivalent ratios by multiplying or dividing both the numerator and denominator of a given ratio by the same number.
