Answer:

Ok so first of all we know that 1% or 1/100 people are allergic to bee stings. In this class their is 25 people and the change of one of them being alergic so 1/25 this is 4 time 1/00 so

4%

Hope This Helps!!!

Answer:

.25%

Step-by-step explanation:

it would be 1/4 of one percent

1% of all people means 1 out of 100

now we want to find 1% out of 25

which would equal .25% or 1/4 of 1%

James folds a piece of paper in half several times,each time unfolding the paper to count how many equal parts he sees. After fo
Snezhnost [94]

Answer:

There will be total 2048 parts of the given paper if James if able to fold the paper eleven times.

The needed function is y = 2 ^n

Step-by-step explanation:

Let us assume the piece of paper James decides to fold is a SQUARE.

Now, let us assume:

n : the number of times the paper is folded.

y : The number of parts obtained after folds.

Now, if the paper if folded ONCE ⇒  n = 1

Also, when the pap er is folded once, the parts obtained are TWO equal parts.

⇒  for n = 1 , y = 2       ..... (1)

Similarly, if the paper if folded TWICE  ⇒  n = 2

Also, when the paper is folded twice, the parts obtained are FOUR equal parts.

⇒  for n = 2 , y = 4       ..... (2)

⇒y  = 2^2  =  2^n

Continuing the same way, if the paper is folded SEVEN times  ⇒  n = 7

So, y = 2^ n = 2^7 = 128

⇒  There are total 128 equal parts.

Lastly,  if the paper is folded ELEVEN  times  ⇒  n = 11

So, y = 2^ n = 2^{11} = 2048

⇒  There are total 2048 equal parts.

Hence, there will be total 2048 parts of the given paper if James if able to fold the paper eleven times.

And the needed function is y = 2 ^n

Write an expression that can be used in over a temperature from degrees Celsius see to degrees Fahrenheit and then use the expre
densk [106]

Answer:

25°C = 77 degree Fahrenheit.

Step-by-step explanation:

In this question we have to write the expression showing the relation between degree Celsius and degree Fahrenheit first.

C=\frac{5}{9}(F-32)  where C = degree centigrade and F = degree Fahrenheit

Although the question is not clear in the next part but assuming that we have to use this expression to convert 25°C to degree Fahrenheit,

We will plug in the value of C in the expression,

25=\frac{5}{9}(F-32)

F=(\frac{9}{5}\times 25)+32

F = 45 + 32

F = 77

Therefore, 25°C = 77 degree Fahrenheit will be the answer.
