Question

Mathematics
1 answer:
Ahat [919]3 years ago
8 0

Answer:

4 minutes.

Step-by-step explanation:

There are three trains that Rachel has to take to go to her job. The total time is taken by her, on average, 1 hour and 20 minutes i.e. (60 + 20) = 80 minutes.

In his journey, she walks for 15 minutes and a train journey for about 53 minutes.

Then the total waiting time for the trains is (80 - 53 - 15) = 12 minutes.

Therefore, the average waiting time, in minutes, at each of the three train stations will be \frac{12}{3} = 4 minutes. (Answer)

Determine if the given ordered pair is a solution to the equation. Show work full.
sleet_krkn [62]

Answer:

The ordered pair is not a solution of the equation

Step-by-step explanation:

we know that

If a ordered pair is a solution of a linear equation, then the ordered pair must satisfy the linear equation

we have

y=-3x-13

Substitute the value of x and the value of y of the given ordered pair in the linear equation and analyze the results

For x=-1, y=15

15=-3(-1)-13

15=3-13

15=-10 ----> is not true

so

the ordered pair not satisfy the equation

therefore

The ordered pair is not a solution of the equation

Which of the following statements is not​ true? A. If the probability of an event occurring is​ 0, then it is impossible for tha
FromTheMoon [43]

Answer:

C. If the probability of an event occurring is​ 1.5, then it is certain that the event will occur.

Step-by-step explanation:

Probability is a value between <em>0 and 1</em> (including both values). Thus, to say that there is a probability of 1.5 is not correct, and, therefore, this statement is not true.

We can rewrite the statement as "If the probability of an event occurring is 1, then it is completely certain that the event will occur."

Statement A.

Suppose the event is A. Then, if P(A) = 0, it is completely certain that the event will not occur. It is true.

Statement B.

\\ if P(A) = 0\;then\;P(\overline{A}) = 1 - 0 = 1. Then, the statement is true.

Statement C.

We already explained the <em>statement C is not true</em> because the values for probabilities are between 0 and 1 (including both values). A probability of 1.5 is meaningless as a result.

Statement D.

For the same reason explained in C, the probability can never be a negative value. So, this statement is also true.

Please help with math
kykrilka [37]

Answer:

2nd option, x > 1.10

Step-by-step explanation:

7e^{2x}-5 > 58

Add 5 to both sides,

7e^{2x}-5+5 > 58 +5\\7e^{2x} > 63

Divided both sides by 7,

\frac{7e^{2x}}{7} > \frac{63}{7}

e^{2x} > 9

Apply Exponent Rule,

2x > 2ln(3)

\frac{2x}{2} > \frac{2ln(3)}{2}

x > ln(3) or x > 1.09861
