The lowest elevation in Nevada is about 65
meters below sea level. The lowest elevation in
Florida is about 2/5the value of the lowest
elevation in Nevada. Which value best represents
the lowest elevation, in meters, in Florida?

Answers

Answer:

-26 meters

Step-by-step explanation:

first do 65/5 because it is asking how much less florida´s elevation is than nevada´s. and because it is a fraction you do it divided by 5.

65/5=13

so now because the fraction was 2/5 do 13+13

you get 26. so florida´s lowest point is -26 meters.

Which situation involves a conditional probability? O A. The probability that you roll a 6 on a number cube B. The probability that you make two free throws in basketball C. The probability that you make a second free throw given that you made the first free throw O D. The probability that you are given a book for your birthday

Answers

Answer:

Step-by-step explanation:

its conditional because you might not make the first free throw.

The situation that involves a conditional probability is the probability that you make a second free throw given that you made the first free throw.

Thus, option (C) is correct.

Conditional probability refers to the probability of an event occurring given that another event has already occurred.

In this case, the probability of making a second free throw is dependent on the condition that you made the first free throw.

Therefore, the probability that you make a second free throw given that you made the first free throw.

Step-by-step explanation:

we have

5x+4=2x+9

5x-2x=9+4

3x=13

x=13/3

Answer:

x = 13/3

Step-by-step explanation:

Now we have to,

→ find the required value of x.

Forming the equation,

→ 2x + 9 = 5x - 4

Then the value of x will be,

→ 2x + 9 = 5x - 4

→ 2x - 5x = -4 - 9

→ -3x = -13

→ x = (-13)/(-3)

→ [ x = 13/3 ]

Hence, the value of x is 13/3.
