If 47% of a schools population are girls what percentage are boys?

Answers

Answer:

53% is the answer

Step-by-step explanation:

100%-47= 53%

Answer:

53% of the school is boys

Step-by-step explanation:

I can't really explain this in full detail since its pretty simple but all we would have to do is take 100 (the full precentage) and subtract 47 from it because we know that this is the precentage of girls in the school, and our answer would be 53%.

The graph shows an exponential relationship between x and y.

1 Write an equation representing this relationship.

2 What is the value of y when x=-1?

3 What is the value of y when x=-2?

Answers

Answer:

1. y = 50 x [tex]2^{x}[/tex]

2. 25

3. 12.5

Step-by-step explanation:

You can see by the graphs the numbers are doubling by each year. For the last two questions plug in the number to the equation and you should get the same answer.

Hope this helps!

1)The equation representing this relationship is y=50×2ˣ.

2)The value of y when x=-1 will be 25.

3)The value of y when x=-2 will be 12.5.

What is an exponential function?

The exponential function is classified as a function that increases swiftly and whose value is always positive. using the exponent y = aˣ,, where an is a constant greater than 1, and a>1.

It is given that the graph shows an exponential relationship between x and y.

The standard exponential function is,

y=baˣ

y=50×2ˣ

2)
When x= -1 the obtained value of y is,

y=50×2ˣ

y=50×2⁻¹

y=50/2

y=25

When x= -2 the obtained value of y is,

y=50×2ˣ

y=50×2⁻²

y=50/4

y=12.5

Thus, the equation for this relationship is y=50×2ˣ,, where the values of y at x=-1 and x=-2 are 25 and 12.5, respectively.

There are 6 fiction books in the bin. The probability of randomly selecting a fiction book from the bin is 0.6 or 3/5.

Step-by-step explanation:

The third bullet point says that the probability of selecting a poetry book is 1/5, and the second point says that the probability of selecting a fiction book is three times as likely than the poetry books. So that would mean we must multiply 1/5 by 3. So do that you could turn it into a decimal first. 1/5 as a decimal is 0.2. Next, we multiply it. So 0.2 times 3 equals 0.6. Therefore the answer is 0.6. And to convert that back to a fraction, it would be 3/5.

6 fiction books in the bin :) I hope this helps!!
