Answer:

  63

Step-by-step explanation:

Reversing the digits changes the value by a factor of 9 times the difference in the digit values. Here, this means the digits differ by 27/9 = 3. If one digit is double the other, the higher digit is 2×3 = 6.

The number is 63.

_____

If you like, you can work through the algebra of it. Let the original number have tens digit x and ones digit y.

  original number value = 10x +y

  reversed number value = 10y +x

  difference of values = 27 = (10x +y) -(10y +x) = 9(x -y)

The tens digit is twice the ones digit, so we have ...

  x = 2y

Substituting in the difference equation, we have ...

  27 = 9(x -y)

  3 = (2y -y) = y . . . . . divide by 9, substitute for x

  x = 2(3) = 6

The number is 10x+y = 63.

Answer: An elephant’s trunk is usually around 6 feet in length, but can be up to 7 feet long. The trunk alone can weigh as much as 140 kg and can hold 12 litres of water. How fast do elephants run? Elephants can run faster than you would expect, easily reaching speeds of 40 mph - a lot faster than us humans can run!

Step-by-step explanation:

The domain of [tex]f[/tex] is non-negative real numbers, and the domain of [tex]g[/tex] is real numbers.

[tex](f\circ g)(x) = 2\sqrt{2}|x|^5[/tex] (I skipped calculation details), so [tex](f\circ g)(9) = 2 \sqrt{2} \cdot 9^5[/tex].

Answer:

i tink is b

Step-by-step explanation:

The equation that represents the situation will be 4r + 350 = 550. Then the correct option is A.

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

A family is driving 550 miles to their grandmother's house. They have already driven 350 miles.

Let 'r' be the speed of the car in miles per hour. The family must drive to reach their grandmother's house in 4 hours. Then the equation is given as,

4r + 350 = 550

The equation that represents the situation will be 4r + 350 = 550. Then the correct option is A.

Answer:

(a) Mean and Median of type A

[tex]\bar x = 2145.47[/tex]

[tex]Median = 966[/tex]

(b) Mean and Median of type B

[tex]\bar x = 531.73[/tex]

[tex]Median = 366[/tex]

(c) The claim by the public health worker is true.

Step-by-step explanation:

Given

[tex]Type\ A: 38\ 100\ 186\ 199\ 253\ 380\ 595\ 966\ 1611\ 2638\ 3845\ 4931\ 5183\ 5367\ 5890[/tex]

[tex]Type\ B: 59\ 95\ 116\ 143\ 156\ 225\ 271\ 366\ 495\ 696\ 851\ 1060\ 1140\ 1101\ 1202[/tex]

[tex]n = 15[/tex]

Solving (a): The mean and median of A.

Mean is calculated using:

[tex]\bar x = \frac{\sum x}{n}[/tex]

[tex]\bar x = \frac{38 +100 +186 +199+ 253+ 380+ 595+ 966 +1611 +2638 +3845+ 4931+ 5183 +5367 +5890 }{15}[/tex]

[tex]\bar x = \frac{32182}{15}[/tex]

[tex]\bar x = 2145.47[/tex]

The median is calculated using:

[tex]Median = \frac{n+1}{2}th[/tex]

[tex]Median = \frac{15+1}{2}th[/tex]

[tex]Median = \frac{16}{2}th[/tex]

[tex]Median = 8th[/tex]

The 8th item is: 966

So:

[tex]Median = 966[/tex]

Solving (b): The mean and median of B.

Mean is calculated using:

[tex]\bar x = \frac{\sum x}{n}[/tex]

[tex]\bar x = \frac{59 +95 +116+ 143+ 156+ 225+ 271+ 366+ 495 +696+ 851+ 1060+ 1140 +1101+ 1202}{15}[/tex]

[tex]\bar x = \frac{7976}{15}[/tex]

[tex]\bar x = 531.73[/tex]

The median is calculated using:

[tex]Median = \frac{n+1}{2}th[/tex]

[tex]Median = \frac{15+1}{2}th[/tex]

[tex]Median = \frac{16}{2}th[/tex]

[tex]Median = 8th[/tex]

The 8th item is: 366

So:

[tex]Median = 366[/tex]

(c) The claim by the public health worker is true.

To do this, we simply compare the mean value of both types.

For Type A

[tex]\bar x = 2145.47[/tex]

For Type B

[tex]\bar x = 531.73[/tex]

The claim is:

[tex]Type\ A > 2 * Type B[/tex]

[tex]2145.47 > 2 * 531.73[/tex]

[tex]2145.47 > 1063.46[/tex]

Since the inequality is true, then the claim is true
