What is the probability that a person who is above 35 years old has a hemoglobin level of 9 or above?
lorasvet [3.4K]

Answer:

Option C. P=0.531

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.  

The size of the sample space is the total number of possible outcomes  

The event space is the number of outcomes in the event you are interested in.  

so  

Let

x------> size of the event space  (total person's hemoglobin level of 9 or above with age above 35 years)

y-----> size of the sample space  (total person's age above 35 years)

so

P=\frac{x}{y}

In this problem we have

y=162

Complete the table to find the total person's hemoglobin level of 9 or above (person's age above 35)

Let

y------> total person's hemoglobin level between 9 and 11 (person's age above 35)

y+76+40=162

y=46

Find the value of x

x=46+40=86

substitute the values

P=\frac{86}{162}=0.531

What is the equation of the line that passes through the point (-5,1) and has a slope of -1/5?
olchik [2.2K]

Answer:

x + 5y = 0

Step-by-step explanation:

y = mx + b

y = -1/5 x + b

1 = -1/5 (-5) + b

1 = 1 + b

b = 0

y = -1/5 x

5y = -x

x + 5y = 0

What is the solution to 3 times the square root of 4 minus 2 times the square root of 4? A. 0 B. 1 C. 2 D. 3
olasank [31]

For this case we have the expression:

"the square root of 4" is represented algebraically as:

\sqrt {4}

Then, we can express the given statement as:

3 \sqrt {4} -2 \sqrt {4} =

They are similar terms, we can subtract:

3 \sqrt {4} -2 \sqrt {4} = \sqrt {4} = \sqrt {2 ^ 2}

By definition of power properties we have that:

\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a

Then the expression is reduced to:

\sqrt {2 ^ 2} = 2

Answer:

3 \sqrt {4} -2 \sqrt {4} = 2
