Please could with some help of: solve 4x + 11 < 23

Answers

Answer 1

Answer: When dealing with inequalities your main goal is to isolate x. So you do whatever it takes to get X alone on one side.
4x+11<23
4x<12
x<3

Answer 2

Answer: x<3
First, you subtract the 11 from both sides of the equation:
4x+11<23
-11<-11
  4x<12
Next, divide both sides of the inequality by 4:
  4x<12
4 < 4
  x<3

Answers

1). Flipping a coin or picking a number are not dependent. The probability
of the result is the same every time. It only changes if you leave out what
you picked the first time, because then the total number of possibilities is
different.
With this reasoning, they might say that iii. is dependent because you
don't replace what you draw the first time. I'm not comfortable with that.
Sure, you don't replace the first number you picked, but how many odd
numbers are left ? Still an infinite number.
So I think iii. is the answer they want here, but I don't think any of the
choices is really dependent.

2). By the same reasoning, i. and ii. are independent. The coins have
no memory. They don't remember what happened last time.

3). The probability of any result is

(number of successes)/(number of possibilities).

Total number of possibilities each time is 8.

Probability of an even number (2, 4, 6, or 8) the first time = 4/8 = 0.5

Probability of an odd number (1, 3, 5, or 7) the second time = 4/8 = 0.5

Probability of an 8 the third time = 1/8 = 0.125 .

Probability of all 3 events = (0.5) x (0.5) x (0.125) = 0.03125 (3.125%)

A tank has an opening through which water leaks out. The table below shows the amount of water, in gallons, in the tank after different amounts of time, in hours:What type of association will the scatter plot for this data represent between the number of hours and the amount of water in the tank, in gallons?
A negative nonlinear association
A positive linear association
A positive nonlinear association
A negative linear association

Answers

Answer: A negative linear association

Step-by-step explanation:

From the given table in the picture , it can be seen that as the time is increasing the amount of water in tank decreases, it indicates that there is a negative association between the two variables.

Also, the rate of change in amount of water is constant as 0.5 gallon per hour.

It implies there is a linear association.

Now, the scatter plot for this data represents there is a negative linear association between the number of hours and the amount of water in the tank, in gallons.

It is a negative linear association because it descends at a constant rate of .5 making it linear but the line is going down making it negative
