Answer:

x = \sqrt{13}

Step-by-step explanation:

The line from the vertex to the base is a perpendicular bisector and divides the triangle into 2 right triangles.

Consider the right triangle on the left with base 2

Using Pythagoras' identity

The square on the hypotenuse (x) is equal to the sum of the squares on the other 2 sides, that is

x² = 2² + 3² = 4 + 9 = 13 ( take the square root of both sides )

x = \sqrt{13}

Express a decimal number ( ie 0.768) - process description please - as a rational number (96/125)?
Stels [109]

The decimal representation of any number is a linear combination of powers of 10. In other words, given a number like 123.456, we can expand it as

1\cdot10^2+2\cdot10^1+3\cdot10^0+4\cdot10^{-1}+5\cdot10^{-2}+6\cdot10^{-3}

10^{-n}=\dfrac1{10^n} for any n, so the above is the same as

100+20+3+\dfrac4{10}+\dfrac5{100}+\dfrac6{1000}=\dfrac{100000+20000+3000+400+50+6}{1000}=\dfrac{123456}{1000}

Similarly, we can write

0.768=\dfrac{768}{1000}

Now it's a question of reducing the fraction as much as possible. We have \mathrm{gcd}(768,1000)=8 so

\dfrac{768}{1000}=\dfrac{96\cdot8}{125\cdot8}=\dfrac{96}{125}

The five-number summary for the number of teams in each of Brad's fantasy football leagues is shown in the following table.
Westkost [7]

Answer:

The correct option is (C) 10.

Step-by-step explanation:

The five-number summary for the number of teams in each of Brad's fantasy football leagues is as follows:

Minimum: 4

<em>Q</em>₁: 7

Median: 10

<em>Q</em>₃: 14

Maximum: 18

The minimum value is the smallest value in the data set.

The first quartile (<em>Q</em>₁) is the value that is less than 75% of the observations.

The median is the middle most value of the data set. It is the value that is less than 50% of the observations.

The third quartile (<em>Q</em>₃) is the value that is less than 25% of the observations.

And the maximum value is the largest value in the data set.

So, the five-number summary suggests that about 50% of Brad's fantasy football leagues have fewer than 10 teams.

Thus, the correct option is (C).

DO IT FOR TIMOTHEE
Arte-miy333 [17]

Answer:

Via its graph, you can identify exponential and linear functions. Linear functions are straight lines, while curved lines are exponential functions. By the adjustment in y, you can also recognize them. If you apply the same number to y, then the function changes continuously and is linear.
