During the months of August and September the total rainfall I August was 0.6 inch more than the amount f rainfall in September, how much rain fell in each month?

Answers

Answer:

August = 3.4

September = 2.8

Step-by-step explanation:

Given

[tex]Total = 6.2\ in[/tex]

Represent August with A and September with S.

So,

[tex]A =S + 0.6[/tex]

Required

Amount of rainfall in each month.

This is calculated using:

[tex]Total = August + September[/tex]

[tex]6.2= A + S[/tex]

Recall that: A = S + 0.6. Substitute

[tex]6.2= S + 0.6 + S[/tex]

[tex]6.2= 2S + 0.6[/tex]

Collect Like Terms

[tex]2S = 6.2 - 0.6[/tex]

[tex]2S =5.6[/tex]

Solve for S

[tex]S = 5.6/2[/tex]

[tex]S = 2.8[/tex]

Substitute 2.8 for S in [tex]A =S + 0.6[/tex]

[tex]A = 2.8 + 0.6[/tex]

[tex]A = 3.4[/tex]

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

7 times the sum of y and 1/3

This can be written as,

= 7 (y + 1/3)

=7 (3y + 1) / 3

= 7/3 (3y + 1)

Thus,

The algebraic expression of 7 times the sum of y and 1/3 is

7/3 (3y + 1).

Answers

Answer:

  14.9 cm

Step-by-step explanation:

To find c using the Law of Sines, you must know angle C. That is found from ...

  C = 180° -A -B = 180° -150° -12° = 18°

Then the law of sines tells you ...

  c/sin(C) = b/sin(B)

  c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)

  c ≈ 14.9 cm

The phone lines to an airline reservation system are occupied 61% of the time. Assume that the events that the lines are occupied on successive calls are independent. If 11 calls are placed, what is the probability that the lines are occupied for exactly 5 calls

Answers

Answer:

0.1373 = 13.73% probability that the lines are occupied for exactly 5 calls

Step-by-step explanation:

For each call, there are only two possible outcomes. Either the lines are occupied, or they are not. The events that the lines are occupied on successive calls are independent. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The phone lines to an airline reservation system are occupied 61% of the time.

This means that [tex]p = 0.61[/tex]

If 11 calls are placed, what is the probability that the lines are occupied for exactly 5 calls

This is P(X = 5) when n = 11. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 5) = C_{11,5}.(0.61)^{5}.(0.39)^{6} = 0.1373[/tex]

0.1373 = 13.73% probability that the lines are occupied for exactly 5 calls

Which proportional relationship has the greatest rate of change?

Answers

Answer:

Option (1)  ;   y = 7x

Step-by-step explanation:

(1) reads y = 7x, a line with slope 7, therefore the rate of change in this is 7

(2) says that y increases 12 units every time that x increases 4 Then the rate of change is: (increase in y / increase in x = 12/4 =3

(3) shows a table from which we can see that an increase of y in 8 corresponds to an increase of x in 2:  rate of change = (8 - 0) , (2 - 0) = 4

(4) shos a line with slope (rate of change) given by:  (12 - 0) / (2 - 0) = 12/2 = 6

Therefore, the greatest rate of change is shown by the first expression
