Answer:

The answer to your question is No

Step-by-step explanation:

To answer this question use the Vertical line test. This test states that if we draw a vertical line and intercepts the function only in one point it is a function.

It the vertical line intersects the graph in two or more points, it is not a function.

See the picture below

The graph given is not a function because the vertical line crosses the graph in three points.

An equilateral triangle has sides 8 units long. An equilateral triangle with sides 4 units long is cut off at the top, leaving a
Darina [25.2K]

Answer:

1:3

Step-by-step explanation:

Please study the diagram briefly to understand the concept.

First, we determine the height of the isosceles trapezoid using Pythagoras theorem.

4^2=2^2+h^2\\h^2=16-4\\h^2=12\\h=\sqrt{12}\\ h=2\sqrt{3}$ units

The two parallel sides of the trapezoid are 8 Inits and 4 units respectively.

Area of a trapezoid =\dfrac12 (a+b)h

Area of the trapezoid

=\dfrac12 (8+4)*2\sqrt{3}\\=12\sqrt{3}$ Square Units

For an equilateral triangle of side length s.

Area  =\dfrac{\sqrt{3}}{4}s^2

Side Length of the smaller triangle, s= 4 Units

Therefore:

Area of the smaller triangle

=\dfrac{\sqrt{3}}{4}*4^2\\=4\sqrt{3}$ Square units

Therefore, the ratio of the area of the smaller triangle to the area of the trapezoid

=4\sqrt{3}:12\sqrt{3}\\$Divide both sides by 4\sqrt{3}\\=1:3

53, 64, 19, 25, 88, 48, 46<br>Mean:<br>Mode:<br>Median:<br>Range:<br>​
levacccp [35]

Answer:

Mean: 49

Mode: none, since all the numbers only appear once

Median: 48

Range: 69

Step-by-step explanation:

53+64+19+25+88+48+46 = 343

343/7= 49 (mean)

19, 25, 26, 48, 53, 64, 88 (middle number is 48, so the median is 48)

Range= largest number-smallest number

88-19= 69 (range)
