The clinical literature reports that the duration of a typical cold is roughly 18 days. Researchers wanted to know if people ten
never [62]

Answer:

0.65

Step-by-step explanation:

Confidence interval can be calculated using the Mean and Margin of error with M±ME where

  • M is the average expected cold days of typical cold.
  • ME is the Margin of error for the confidence interval.

In the question it is given that the researchers reported a 95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.

The minimum value in the confidence interval is M-ME =6.9

The maximum value in the confidence interval is M+ME=8.2

Then we get 8.2-6.9=1.3=M+ME-(M-ME)=2× ME

From this we get ME=0.65

Please help!! I only have 30 minutes left!! Given that x and y are positive integers and (x·2)+x(2^2)+(y·2^3)+(y·2^4)=42, what i
Viktor [21]

Answer:

xy = 3

Step-by-step explanation:

The expression to be evaluated is:

2\cdot x +4\cdot x + 8\cdot y + 16\cdot y = 42

6\cdot x + 24\cdot y = 42

By some algebraic handling:

6\cdot (x + 4\cdot y) = 42

Where:

x+4\cdot y = 7

There is one possible solution:

x = 3, y = 1

And consequently,

xy = 3

Help please with all of them i dint get it
Vlad [161]
1. 1.5x < = 51
     x < = 51/1.5
     x < = 34

2. 2.50x < = 20
    x < = 20/2.5
    x < = 8

3. x/5 < = 4
     x < = 4 * 5
     x < = 20...the maximum would be $ 20

4. not sure how to make this into an inequality...it looks like an equation.
   13/(3 1/4) = x
    13 / (13/4) = x
    13 * 4/13 = x
     4 = x...she can make 4 batches

5. cant see all of it....cant see how many pictures she wants framed

6. 5L < 55
     L < 55/5
     L < 11...

7. 4h > = 100
    h > = 100/4
    h > = 25 hrs babysitting

8. x + 125 + 20 < = 180
    x + 145 < = 180
    x < = 180 - 145
    x < = 35 minutes listening to music
