What is the probability that a person who is above 35 years old has a hemoglobin level of 9 or above? a. 0.357 b. 0.313 c. 0.531 d. 0.343 e. 0.432

Answers

Using it's concept, it is found that the probability that a person who is above 35 years old has a hemoglobin level of 9 or above is of 0.247.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Researching the problem on the internet, we find a table, which says that there are 162 participants above 35 years old, and 40 have hemoglobin levels of 9 and above, hence the probability is given by:

p = 40/162 = 0.247.

Answer:

x(adjucent ) = 3.8

Step-by-step explanation:

okay so you are been giving me a left angle triangle so what you are supposed to do is that the longest part which is indicated 7.4 is called the hypothesis whiles the other side indicated 3.6 is called the opposite and the down part is the adjacent. so to find the adjacent your formula is opposite + adjacent = hypothesis .

so therefore we can see that

3.6 + x = 7.4

x = 7.4 - 3.6

x = 3.8

The ranges values of the function f(x) are: {-89,-9,7} - Option D.

Domain and Range

The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined.

While the domain is related to the values of x, the range is related to the possible values of y that the function can have.

Here, you need to replace the domain values in the given equation.

f(x)=-2x²+9

For x=-3

f(x)=-2*(-3)²+9

f(x)=-2*9+9

f(x)=-18+9=-9

For x=1f(x)=-2*(1)²+9f(x)=-2*1+9f(x)=-2+9=7

Answer:

Yes

Step-by-step explanation:

When there are 2 rows

Number of erasers per row = No. of erasers / No. of rowsNumber of erasers per row = 18/2Number of erasers per row = 9

When there are 3 rows

Number of erasers per row = No. of erasers / No. of rowsNumber of erasers per row = 18/3Number of erasers per row = 6

Answer:

[tex]3 \sqrt{17}[/tex]

Step-by-step explanation:

The given triangle is a right triangle. Therefore, we can use Pythagoras Theorem to find the measure of the third side.

Pythagoras Theorem

[tex]a^2+b^2=c^2[/tex]

where:

a and b are the legs of the right trianglec is the hypotenuse (longest side) of the right triangle

From inspection of the given triangle:

a = 4c = 13

To calculate the measure of the third side "b", substitute the given values into the formula and solve for b:

[tex]\begin{aligned}a^2+b^2 & = c^2\\\implies 4^2+b^2 & = 13^2\\16+b^2 & = 169\\16+b^2-16 & = 169-16 \\b^2 & = 153\\\sqrt{b^2} & =\sqrt{153}\\b & = \sqrt{9 \cdot 17}\\b & = \sqrt{9}\sqrt{17}\\b & = 3\sqrt{17}\end{aligned}[/tex]

Therefore, the measure of the third side of the given right triangle in simplest radical form is [tex]3 \sqrt{17}[/tex].

The difference between a number and three fourths of itself is 15. Find the number.

Answers

Answer:

Step-by-step explanation:

lets say the number is X so:

X-3/4X=15

then multiple both sides by 4 then you will get

4X-3X=60

SO:X=60

Answer:

Step-by-step explanation:

let x be the number that we are trying to figure out.

the statement “The difference between a number and three fourths of itself is 15” means x + (3/4)x = 15

then

(1/4)x = 15

Then

x = 4 × 15

Then

x = 60
