Answer:

B, E, F

Step-by-step explanation:

If we were replacing these numbers with x, it’s simple.

Just know that √144=12

So,

we definitely know √20736 is way bigger that 12.

√143 is less that √144 (which is equal to 12), so this is a correct answer.

√144=12, so this answer is not applicable .

√145 is bigger that √144 (which, again, is equal to 12), so this wouldn’t be a valid answer.

And finally, we have √125 which is smaller that √144 (which, is equal to 12), so this answer is valid.

Let p represent any number in the interval (- 18,22). Rewrite the possible values for p in inequality notation.

Nataliya [291]

Answer:

$-18 < p < 22$

Step-by-step explanation:

We are given the following information in the question.

The open interval: (- 18,22).

Let p belong to the given interval then p represents all the values belonging to the given interval.

Open Interval: An open interval is a interval that does not include the end points.

Thus, we can write:

$-18 < p < 22$

is the required inequality form required.

That is p can take values greater than -18 and smaller than 22.

The sum of three numbers is 100. The second number is 2 times the third. The third number is 8 less than the first. What are the

8_murik_8 [283]

Answer:

Step-by-step explanation:x+y+z=100(let x ,y,z represent the first second and third numbers respectively)

Therefore,y=2z

z=x-8

y=2x-16

substituting the values of x,y and z into the question,we have

x+(2x-16)+(x-8)=100

Simplifying,we have

4x-24=100

adding 24 to both sides of the equation,

4x=100+24

4x=124

dividing both sides of the equation by the co-efficient of x,we have

4x/4=124/4

4.31=124

therefore,x=31.

If the probability of an event is 0.7 repeating, what are the odds against the event

ivann1987 [24]

So the probability is the number of favorable outcomes divided by the number of total outcomes. This means that the favorable outcomes are 7/9, and the unfavorable outcomes are 2/9. The odds against the event are the unfavorable outcomes. Therefore the odds against the event is 2/9, or 0.2 repeating. Hope this helps. Feel free to ask more questions, and feel free to ask questions about my explanation.
