Answer:

\displaystyle \large \boxed{\sf \bf \ \  \lim_{x\rightarrow0} {\dfrac{sin^2(6x)}{9x^2}}=4 \ \ }

Step-by-step explanation:

Hello, sin(x) is equivalent of x when x tends to 0, so

\displaystyle \lim_{x\rightarrow0} {\dfrac{sin^2(6x)}{9x^2}}\\\\=\lim_{x\rightarrow0} {\dfrac{(6x)^2}{9x^2}}\\\\=\lim_{x\rightarrow0} {\dfrac{36x^2}{9x^2}}\\\\=\lim_{x\rightarrow0} {\dfrac{36}{9}}\\\\=4

Thank you.

In the rolling of two fair dice calculate the following: P(Sum of the two dice is 7) = ______
vesna_86 [32]

Answer:

P(Sum of the two dice is 7) = 6/36

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

A fair dice can have any value between 1 and 6 with equal probability. There are two fair dices, so we have the following possible outcomes.

Possible outcomes

(first rolling, second rolling)

(1,1), (2,1), (3,1), (4,1), (5,1), (6,1)

(1,2), (2,2), (3,2), (4,2), (5,2), (6,2)

(1,3), (2,3), (3,3), (4,3), (5,3), (6,3)

(1,4), (2,4), (3,4), (4,4), (5,4), (6,4)

(1,5), (2,5), (3,5), (4,5), (5,5), (6,5)

(1,6), (2,6), (3,6), (4,6), (5,6), (6,6)

There are 36 possible outcomes.

Desired outcomes

Sum is 7, so

(1,6), (6,1), (5,2), (2,5), (3,4), (4,3).

There are 6 desired outcomes, that is, the number of outcomes in which the sum of the two dice is 7.

Answer

P(Sum of the two dice is 7) = 6/36

Blake thinks that the mass of a baby mouse will increase similar to what is shown on the
ira [324]

Answer:

Check below for a lucid explanation.

Step-by-step explanation:

The independent variable is the variable whose variation does not depend on another external variable. It is the variable on the x-axis which in this case is the growth of the baby.

Note: The diagram you attached to this question does not include the calibration on the x - axis which will give us the independent variable at point

This, nevertheless, is a very simple task. Locate the point A on the graph and trace it downwards to the x - axis, the value written where the line coincides with the x -axis is the value of the independent variable( growth of the baby) at point A.
