Answer:

D

Step-by-step explanation:

In order to figure out which of the 4 is a function, you must perform the vertical line test for each. No vertical line should intersect the graph of the relation at more than one point. D is the only one that doesnt hit two points when performing the vertical line test.

Compare the two ratios is 6 : 15 less than 30 : 80 or greater than?
romanna [79]

Work:
6/15 = x/1
To get from 15 to 1, you have to divide by 15. So, to make an equal field, divide 6 by 15.

6 : 15 is the same as 2 : 5 or 0.4.

30/80 = x/1
To get from 80 to 1, you have to divide by 80. So, to make an equal field, divide 30 by 80.

30 : 80 is the same as 3 : 8 or .875.


Comparing the two, 30 : 80 is greater than 6 : 15.


Hope this helps. Have a good day.

If x is a positive integer, for how many different values of x is sq rt 48/X a whole number ?
Sedaia [141]

Answer:

x=3,8,12

Step-by-step explanation:

Hi there this quez is fun thanks for uploading it

√48/x=a whole number

If you divide 48/3 you get 16 whose square root is 4-a whole number

If you divide 48/8 you get 6 whose square root is 3-a whole number.

If you divide 48/12 you get 4 whose square root is 2- a whole number

Which point is NOT on the line y = 5x + 1?
12345 [234]

To find which point is NOT on the line y = 5x + 1, we just need to plug each point into equation y=5x+1 to see which one point satisfies this equation.

check for (1,6)

y=5x+1

or 6=5*1+1

or 6=5+1

or 6=6

Which is TRUE.

--------

check for (2,11)

y=5x+1

or 11=5*2+1

or 11=10+1

or 11=11

Which is TRUE.

--------

check for (0,1)

y=5x+1

or 1=5*0+1

or 1=0+1

or 1=1

Which is TRUE.

--------

check for (-1,6)

y=5x+1

or 6=5*(-1)+1

or 6=-5+1

or 6=-4

Which is FALSE.

--------

Since only point (-1,6) fails to satisfy the given equation hence point (-1,6) is the final answer.

The average cost of tuition and room and board at a small private liberal arts college is reported to be $8,500 per term. A fina
rewona [7]

Answer:

D. +3.82

Step-by-step explanation:

The computation of the test static for this test is shown below:

Data provided in the question

\bar x= $8,745

\mu = $8,500

\sigma = $1,200 and n = 350

Now based on the above information, the test static for this test is

z = \frac{\bar x - \mu}{\frac{\sigma}{\sqrt{n} } }

z = \frac{\$8,745 - \$8,500}{\frac{\$1,200}{\sqrt{350} } } \\

= 3.82

= +3.82

Hence, the test static for this test is +3.82

We simply applied the above formula so that the correct value could come

And, the same is to be considered
