Answer:

No.

Step-by-step explanation:

Reason:

1. the sample size is too small.

2. we dont know the boy-girl ratio in this school. It's possible that there are only 5 girls in the school. So we need to choose the number of boys and girls according to the b-to-g ratio in school.

A pair of intersecting planes and where they intersect
Alexandra [31]

Answer:

Two planes always would intersect at a line, as shown in attached figure below.

Step-by-step explanation:

As we know that

A plane has basically 2 dimensions.

  • length and
  • width

But as the plane is infinitely large, we can say that length and width of a plane is not supposed to be measured. (can not be measured)

Let suppose we have a pair of intersecting planes.

If If two intersecting planes are not parallel, then they would intersect each other somewhere.

BUT

Two planes always would intersect at a line, as shown in attached figure below.

Omg please help me im literally dying
Karolina [17]

Answer:

(-2,3)

Step-by-step explanation:

Multiply -3x+4y=18 with 2:

-6x+8y=36

Add -6x+8x=36 and 6x+2y=-6

10y=30

y=3

So y=3 we can replace y with 3 on any of these two equations:

6x+6=-6

Move the 6 to the other side:

6x=-12

x=-2

So the solution is

(-2,3)

Hope this helps

Someone pls help, its on trig ratios.
Mars2501 [29]

Answer:

BC=12.8,\\AC=15.1

Step-by-step explanation:

In right triangles only, the tangent of an angle is equal to its opposite side divided by its adjacent side.

Therefore, we have the following equation:

\tan 58^{\circ}=\frac{BC}{8}

Solving, we get:

BC=8\tan 58^{\circ}\approx \boxed{12.8}

Also in right triangles only, the cosine of an angle is equal to its adjacent side divided by the hypotenuse of the triangle.

\cos 58^{\circ}=\frac{8}{AC},\\AC=\frac{8}{\cos 58^{\circ}},\\AC\approx \boxed{15.1}

We can also use the Pythagorean theorem now that we've found BC. However, if you choose to do so, make sure you don't use a rounded value for BC, as that could cause a notable deviation in your final answer.

Using the Pythagorean theorem to verify our answers:

8^2+(8\tan 58^{\circ})^2=\left(\frac{8}{\cos 58^{\circ}}\right)^2\:\checkmark
