From the given points that are (3,1),(9,3),(27,9), we can say that x is three times of y. That is

x= 3y

And we need to solve for y. For that, we need to get rid of 3 from the right side by dividing both sides by 3 . And on doing so , we will get

\frac{x}{3} = \frac{3y}{3}

\frac{x}{3}=y

or

y=\frac{x}{3}

Least to greatest 0.94,9.40,0.094,94.0,94.0
sertanlavr [38]
Here's an example number:
123.456
The place values are, from greatest to least:
The 1 is in the <em /><em>hundreds</em> place
The 2 is in the <em /><em>tens</em> place
The 3 is in the <em>ones</em> place
The 4 is in the <em>tenths</em> place
The 5 is in the <em>hundredths </em>place

If you have some number like 9.40 with no decimal point, shifting it will change the value. Moving the decimal one place to the right multiplies the value by ten. (94)
Moving it one place to the rigt divides it by ten. (0.94)

Here's our list from least to greatest:

solve The mean score of a competency test is 60, with a standard deviation of 5. Between what two values do about 68% of the val
Anna11 [10]

Answer:

Between 55 and 65

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 60

Standard deviation = 5

Between what two values do about 68% of the values lie?

By the Empirical Rule, within 1 one standard deviation of the mean. So from 60-5 = 55 to 60+5 = 75.

Standard deviation 12,16,22,23,34,44,46,47,48,64,67,73,83,89, round to nearest tenth
RideAnS [48]

Answer: 23.9


Step-by-step explanation:

1. First, you must calculate the mean, as following:

\frac{12+16+22+23+34+44+46+47+48+64+67+73+83+89}{14}=47.71

2. Now, you should substract the means obtained to every single number of the set and then square it. Add all of them:

(12-47.71)^{2}+(16-47.71)^{2}+(22-47.71)^{2}+(23-47.71)^{2}+(34-47.71)^{2}+(44-47.71)^{2}+(46-47.71)^{2}+(47-47.71)^{2}+(48-47.71)^{2}+(64-47.71)^{2}+(67-47.71)^{2}+(73-47.71)^{2}+(83-47.71)^{2}+(89-47.71)^{2}=7984.86

3. The mean of this is:

\frac{7984.8574}{14}=570.35

4. The square root of this result is:

\sqrt{2.52}=23.88

5. To the nearest tenth, the result is: 23.9
