Answer:

10.3

Step-by-step explanation:

6²+b²=9²

36+b²=81

b²=81-36

b²=45

b=√45

b=6.7

So CE is 6.7.

6²+b²=7²

36+b²=49

b²=49-36

b²=13

b=√13

b=3.6

so EA is 3.6

AC = CE+EA = 6.7+3.6 = 10.3

Andrea wanted to calculate 5% of 300, so she multiplied 300 by 0.5 (300 x 0.5).
Mars2501 [29]
This is because Andrea converted the Percentage wrong.
to Convert a Percent to a Decimal, she should have divided by 100
so  5 divided by 100 = 0.05  [not 0.5]
Andrea should have multiplied 300 by 0.05 instead to get the right answer

quickly finding 10% of a number means to simply move the decimal to the left one place
so  10% of 300 is 30

since  5% is half of 10%
half of 30 is 15

and so  5% of 300 is 15

What is the overlap of Data Set 1 and Data Set 2?
erastovalidia [21]

Answer: Answer:

There is moderate level of overlap between the two data sets.  

Step-by-step explanation:

Overlap of data sets.

Overlap measures the degree of duplication that exists within data sets.

It is an indicator of the degree to which data are identical.

We are given two data sets in the question.

We have to find the amount of overlap in data set 1 and in data set 2.

There are 8 data points in data set 1 as shown in the image.

There are 8 data points in the data set 2 as shown in the image.

Out of the 8 data points for both data set 1 and data set 2, 5 data points overlap each other on 6, 7, 8 and 9.

Thus, we could say there is moderate level of overlap between the two data sets.

The cheetah is the fastest land animal, capiable of attaining a speed of 110 km/h. In August 2009 , the world record for the men
lozanna [386]

Answer:

About 3 times faster

Step-by-step explanation:

Cheetah's speed = 110 km / hr

World 100m sprint record :

Speed of sprinter :

Distance / time

100 m / 9.58s

= 10.438413 m/s

Convert Cheetah's speed to m/s

110 km/hr = (110 * 1000)m / (60 * 60 s)

= 110000 m / 3600 s

= 30.55555 m/s

Number of times cheetah is faster than sprinter :

30.55555 m/s ÷ 10.438413 m/s

= 2.927 times

Complete the first table so that f(x) is a function.
netineya [11]

For f(x) to be a function, the value of x should not be repeated. That is no x value can be more then once.

So the required table is

x   \  \  \ \ \ f(x) \\ -1   \   \   \ \ \ \   2 \\ 2   \ \ \ \ \    -8 \\ 6   \ \ \ \ \   -12

And for g(x) , not to be a function, we have to repeat x value that is

x \ \ \ \ \ \ g(x) \\ -1 \ \ \ \ \ \ 2 \\ -1 \ \ \ \ \ \  -8 \\ 6 \ \ \ \ \ \  -2
