Answer: 3.19

--------------------------------------

Explanation:

S = sum of the siblings
Dividing this sum over the 25 students will give us the average of 3, so, S/25 = 3 which turns into S = 75 when we multiply both sides by 25.

S = 75 means adding up all of the students' sibling counts gets to 75 total.

A new student has 8 siblings, so the total goes to S+8 = 75+8 = 83

Divide this over the new count of 26 to get 83/26 = 3.1923076923077
this rounds to 3.19

Lim t^4 - 6 / 2t^2 - 3t + 7
Harman [31]

I think you meant to say

\displaystyle \lim_{t\to2}\frac{t^4-6}{2t^2-3t+7}

(as opposed to <em>x</em> approaching 2)

Since both the numerator and denominator are continuous at <em>t</em> = 2, the limit of the ratio is equal to a ratio of limits. In other words, the limit operator distributes over the quotient:

\displaystyle \lim_{t\to2} \frac{t^4 - 6}{2t^2 - 3t + 7} = \frac{\displaystyle \lim_{t\to2}(t^4-6)}{\displaystyle \lim_{t\to2}(2t^2-3t+7)}

Because these expressions are continuous at <em>t</em> = 2, we can compute the limits by evaluating the limands directly at 2:

\displaystyle \lim_{t\to2} \frac{t^4 - 6}{2t^2 - 3t + 7} = \frac{\displaystyle \lim_{t\to2}(t^4-6)}{\displaystyle \lim_{t\to2}(2t^2-3t+7)} = \frac{2^4-6}{2\cdot2^2-3\cdot2+7} = \boxed{\frac{10}9}

Does x=3/y show direct variation ​
Nat2105 [25]

No it does not. when solved you should get y=3/x, meaning it shows inverse variation.

Answer:

144

Step-by-step explanation:

48 ÷ 4 (which is how many sides a square has) is 12

So 12x12 because l×w (length and width) and all sides of a square are equal

So the answer would be 144
