if you have 10 fish and three died in 8 more got put in the fish tank then two died how many fish in the tank now

1 answer:

6 0

you have 10 fish and 3 died (must not have been taking very good care of them ?), but it didnt say that you cleaned them out ...

so you still have 10 fish in the tank

8 more got put in, so 10 + 8 = 18 fish

2 died but you STILL didnt take them out, so you have 18 fish in the tank now.

Solve for X Explain if possible :)

The two labeled angles are alternate interior angles, and as such, they are the same.

From this result you can build the equation

$15x-2 = 13x+2$

and solve it for x: subtract 13x from both sides to get

$2x-2=2$

and add 2 to both sides to get

$2x = 4 \implies x = 2$

Check: if we plug the value we found we have

$13\cdot 2 + 2 = 26+2 = 28 = 15\cdot 2 - 2 = 30-2$

So the angles are actually the same, as requested.

Solve for x if the Perimeter = 26 14-2x 2x + 1 3x - 1

sergejj [24]

Answer:

x = 4

Step-by-step explanation:

Perimeter of triangle = sum of all sides

Side 1: 14 - 2x

Side 2: 3x - 1

Side 3: 2x + 1

Perimeter= side 1 + side 2 + side 3

26 = 14 - 2x + 3x - 1 + 2x + 1

26 = 14 - 1 + 1 - 2x + 3x + 2x

26 = 14 + 3x

3x = 12

x = 12/3

x = 4

Step-by-step explanation:

Population size is top 15 ranking restaurants.

Number of draws = 3

Number of observed successes = 5

Probability formula : [r . x } { n -r] [n - x]

solving the equation we get 24 / 91 which is approximately 0.2637

Suppose that you are a member of this arbitration panel. Construct a 95% confidence interval for the true mean return of the inv

lisabon 2012 [21]

Answer: Margin of Error = 1.944

Lower Bound = 3.052

Explanation:-

Attached below is a file for monthly Rate of return. Used an excel sheet to determine the confidence interval which seems relatively easier as compared to manual computation. The range below (A2:A40) shows the monthly

Functions used : Standard Deviation as= STDEV (A2:A40)

Sample Mean = AVERAGE(A2:A40)

Margin of Error = CONFIDENCE.T(D4,D5,D2)

Lower Bound Interval = D6-D7 = -3.052
