A persons blood type is denoted with A, B, and O, and the symbols + and — The blood type A+ is read as A positive the blood type

katrin [286]

Answer:

6. O+ to A+ donors = 90 to 45; 90 : 45 and 90/45

7. AB- donors to AB+ donors = 4 to 6; 4 : 6 and 4/6

8. B+ to total donors = 20 to 195; 20 : 195 and 20/195

9. O- donors to A- donors = 9 to 21; 9 : 21 and 9/21

10. B- donors to B+ donor = 0 to 20; 0 : 20 and 0/20

11. O- donors to total donors = 9 to 195; 9 : 195 and 9/195

12. A+ donors and B+ donors to AB+ donors = 65 to 6; 65 : 6 and 65/6

13. A- donors and B- donors to AB- donors = 21 to 4; 21 : 4 and 21/4

14. the ratio 90/9 is a comparison of O+ donors to O- donors

Step-by-step explanation:

A ratio is a relationship where for every x unit of one quantity there are y units of another quantity. A ratio can be written in three ways:

x to y

x:y, or

x/y

For the given questions;

6. O+ to A+ donors = 90 to 45; 90 : 45 and 90/45

7. AB- donors to AB+ donors = 4 to 6; 4 : 6 and 4/6

8. B+ to total donors = 20 to 195; 20 : 195 and 20/195

9. O- donors to A- donors = 9 to 21; 9 : 21 and 9/21

10. B- donors to B+ donor = 0 to 20; 0 : 20 and 0/20

11. O- donors to total donors = 9 to 195; 9 : 195 and 9/195

12. A+ donors and B+ donors to AB+ donors

A+ donors and B+ donors to = 45 + 20 = 65

therefore, A+ donors and B+ donors to AB+ donors = 65 to 6; 65 : 6 and 65/6

13. A- donors and B- donors to AB- donors

A- donors and B- donors = 21 + 0= 21

therefore, A- donors and B- donors to AB- donors = 21 to 4; 21 : 4 and 21/4

14. O+ donors = 90; O- donors = 9

therefore, the ratio 90/9 is a comparison of O+ donors to O- donors

forsale [732]

A range is the amount of time from a start of the action up to the end of the action so in your question where a function is created to present the amount of text sent each month. So the best possible restriction of the range is "The range would only include positive integers"

The true average strain in a way that conveys information about precision and reliability is 27.314.

Given that sample size is 20, mean is 26%, standard deviation is 3.4, confidence level is 95%.

We have to calculate the true average strain in a way that conveys information about precision and reliability.

We have to use t test in our problem because sample size is less than 30.

Weknow that,

t=x bar-μ/s $\sqrt{n}$

where μ is sample mean,

s is sample standard deviation.

Degree of freedom=n-1

=20-1

=19

T value at 95% confidence interval=1.7281

put the values in the formula of t given above.

1.7291=x bar-26/3.4/ $\sqrt{20}$

1.7291=xbar-26/3.4/4.47

1.7291= x bar-26/0.76

1.7291*0.76=x bar-26

1.314=x bar-26

x bar=26+1.314

x bar=27.314

After rounding it will be 27.31

Hence the true average strain in a way that conveys information about precision and reliability is 27.31%.
