The probability of having a hemoglobin level above 11 is . Being older than 25 years and having a hemoglobin level above 11 dependent on each other.

Answers

Answer 1

Answer:

The probability of being older than 25 years and having a hemoglobin level above 11 is 19.58%. Since the question is referring to persons older than 25 years, we'll include all the data above 25 years.

So under 25-35 years old is 44 and under 35 years old is 40.

44 + 40 = 84

84 / 429 = 0.1958 or 19.58%

The probability of having a hemoglobin level above 11 is 35.66%. We would just get the ratio of 153 people who have hemoglobin level above 11 over the population of 429. 153 / 429 = 0.356643 or 35.66%

Being older than 25 years and having a hemoglobin level above 11 is not dependent on each other. Since the data is inversely proportional. The older the person gets, the lesser the number of people having hemoglobin level above 11 (A) 19.58%.

I hope this helps!

Answer 2

The solution is, The probability of being older than 25 years and having a hemoglobin level above 11 is 19.58%.

What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

from the given information , we get,

Since the question is referring to persons older than 25 years, we'll include all the data above 25 years.

So under 25-35 years old is 44 and under 35 years old is 40.

44 + 40 = 84

84 / 429 = 0.1958 or 19.58%

so, we have,

There are 280 pieces of fruit in a fruit salad. There are twice as many raspberries as blueberries, three times as many grapes as cherries, and four times as many cherries as raspberries. How many cherries are there in the fruit salad?

Answers

Answer:

64 cherries

Step-by-step explanation:

Given that

There are 280 pieces of fruit in a fruit salad

There are twice as many raspberries as blueberries,

three times as many grapes as cherries,

and four times as many cherries as raspberries

We need to find out the number of cherries in the fruit salad

So,

Let us assume the blueberries be x

So, the raspberries be 2x

Cherries be 8x

And, grapes be 24x

Now

x + 2x + 24x + 8x = 280

35x = 280

x = 8

hence, the No of cherries in the salad

= 8 x

= 8(8)

= 64 cherries

How can we use 40% to help calculate 4%? 400% 1%?

Answers

Answer:

To help find a percent of a whole number

1. out output value is 400

2. we represent the unkown value with x

3. from step 1 above 400=100%

4. similarly, x=40%

5. This results in a pair of simple equations

400=100%(1)

x=40%(4)

6. By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have

[tex]\frac{400}{x} = \frac{100}{40}[/tex]

7. Again, the reciprocal of both sides gives

[tex]\frac{4}{400} = \frac{40}{100}[/tex]

⇒ x=160

Therefore, 40% of 400 is 160
