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

Answer:

The answer is C. 0.531

Step-by-step explanation:

Because

76+x+40= 162.

x= 162-76-40

x= 46

Hence,

40+46=86.

Therefore, probability that a person who is above 35 years old has a hemoglobin level of 9 or above is,

86/162= 0.531.

Solve 3x + 7 > -x - 9. Show each step of your work.
Kruka [31]

Answer:

x > -4

Step-by-step explanation:

Inequalities like these are solved the same way equations are solved, except when multiplying both sides you flip the less than/greater than sign:

3x + 7 > -x -9

3x + 7 - 7 > -x -9 -7     Subtract 7 from both sides

3x > -x -16

3x + x > -x -16 + x     add x to both sides

4x > -16

\frac{4x}{4} > \frac{-16}{4}     divide both sides by 4

x > -4

In this case the inequality sign did not have to be flipped since we never multiply both sides by a negative number.

Help me please with math
koban [17]

Answer:

2) y = x - 4

   y = -x + 2

   => x - 4 = -x + 2

   => 2x = -6

   => x = -3

   => y = -3 - 4 = -7

3) y = 3x + 1

   y = 5x - 3

   => 3x + 1 = 5x - 3

   => 2x = 4

   => x = 2

   => y = 3(2) + 1 = 7

4) 2x + y = 8 => y = -2x + 8

   y = x - 7

   => -2x + 8 = x - 7

   => 3x = 15

   => x = 5

   => y = 5 - 7 = -2
