The ages of the members of a gym have a mean of 4747 years and a standard deviation of 1111 years. what can you conclude from c

Bond [772]

Chebyshev came up with the limits on how much or how many of the data must lie close to the mean. In specific for any positive k, the proportion of the data that lies within k standard deviations of the mean is at least: 

1 - 1/k²

In this problem the mean is 47 yrs therefore:

(47 – 17.3) = 29.7 = (76.7 - 47)

The value of k is calculated using the formula:

29.7 / 11 = 2.7 = k

So the % of gym members aged between 19.4 and 76.6 is: 

1 - 1 / (2.6)² = 0.863 = 86.3 %

Therefore 86.3% of the gym members are aged between 19.4 and 76.6

Which composition of transformations maps figure EFGH to figure E"F"G"H"?

Lady bird [3.3K]

The transformations would map EFGH to ${\text{E''F''G''H''}}$ is a reflection across line k followed by a translation down. Option (a) is correct.

Further explanation:

Given:

The compositions of transformations from EFGH to ${\text{E''F''G''H''}}$ are as follows,

(a). A reflection across line k followed by a translation down.

(b). A translation down followed by a reflection across line k.

(c). A ${180^ \circ }$ rotation about point G followed by a translation to the right.

(d). A translation to the right followed by a ${180^ \circ }$ rotation about point G.

Explanation:

Translation can be defined as to move the function to a certain displacement. If the points of a line or any objects are moved in the same direction it is a translation.

Rotation is defined as a movement around its own axis. A circular movement is a rotation.

The transformations would map EFGH to ${\text{E''F''G''H''}}$ is a reflection across line k followed by a translation down. Option (a) is correct.

Option (a) is correct.

Option (b) is not correct.

Option (c) is not correct.

Option (d) is not correct.

20% of 57 is what number ? The proportion is ?

Elanso [62]

Answer:

11.4

20/100 = x/57

Step-by-step explanation:

It is perhaps simplest just to translate the given English sentence into a mathematical sentence.

... 20% ... ... of ... 57 ... is ... what number

... 20/100 ... × ... 57 .... = ... what number . . . . . . . . translation to math sentence

... 11.4 = what number . . . . . . . . carry out the multiplication

_____

If you're asked to write this as a proportion, you can write it like this:

$\dfrac{20}{100}=\dfrac{\text{what number}}{57}$

You can solve this proportion by multiplying by 57 (the denominator under "what number"). Doing so gives you the same arithmetic sentence as shown above.
