Answer:

D. -6 + 2\sqrt{5}

Step-by-step explanation:

The answer is D because to solve for X you use the quadratic formula which is...

-b±\sqrt{b^{2} - 4ac}

now just plug in which would be

-6±\sqrt{6^{2} - 4(1)(4) }

then solve and the final answer would be

-6 ± 2\sqrt{5} but there is only one answer for this which is a positive that is how I got  

-6 + 2\sqrt{5}

Dovator [93]

Answer:

Yes, the graph makes it appear as if sales increased three folds.

Step-by-step explanation:

The graph presented by the advertising company is misleading, as it attempts to exaggerate the effect of its advert on sales. This can be attributed to the scale which is isn't uniform.

Last year sale was about 137000 and it grew to 150000 as a result of advertisement.

But from the bar chart, it seems there was three times increase in sales.

The probability of getting heads on a single coin flip is
torisob [31]

Answer:

I hope this helps :D

Step-by-step explanation:

4

It can be done a lot easier: instead of calculating the probability of one head, two heads, three heads, ... one just needs to calculate the probability of no heads: that is simply 0.5

0.5

n

. If you subtract it from 1, you get the probability you want: it's because that's the chance of not no heads, meaning at least one head. So, the formula is: 1−0.5

1

−

0.5

n

More formally: if X is throwing at least one head,

()=1−(¬)

P

(

X

)

=

1

−

P

(

¬

X

)

, where ¬

¬

X

is throwing zero heads.

A potter uses three fifths of a pound to make a bowl, how many bowls can a potter make from ten pounds?
mestny [16]
One bowl needs 3/5 of a pound. Knowing that, we just need to find out how many 3/5s may fit in 10:

10 ÷ 3/5 =
= 10 * 5/3 =
= 50/3 =
= 16 2/3

Assuming the potter can't make a 2/3 of a bowl, he'll be able to make 16 bowls from 10 pounds.
