Answer:

x=ce-4/7

Step-by-step explanation:

ce = 7x +4

ce + (-4) = (7x +4) + (-4)

ce - 4 = 7 X + 4 - 4

x= ce-4/7

Answer:

x = \frac{y}{7} - \frac{4}{7}

Step-by-step explanation:

Since it will be easier, just set "ce" as one term. Let ce = y

You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS.

First, subtract 4 from both sides:

y = 7x + 4

y (-4) = 7x + 4 (-4)

y - 4 = 7x

Next, Divide 7 from both sides:

(y - 4)/7 = (7x)/7

(y - 4)/7 = x

x = (y/7) - (4/7)

Your value of x is \frac{y}{7} - \frac{4}{7}

the points (0,1), (1,5), (2,25), (3,125) are on the graph of a function which equation represent that function
8090 [49]

f(x) = 5^{x}

note the range is {1, 5, 25, 125 } which can be expressed as

{ 5^{0}, 5^{1}, 5^{2}, 5^{3} }

the exponents being the domain { 0, 1, 2, 3 }

thus f(x) = 5^{x} an exponential function

Ten major recording acts are able to play at the stadium. If the average profit margin for a concert is $175,000, how much would
nikitadnepr [17]

Answer: Total amount the stadium would clear for all of these events combined is $1750000

Step-by-step explanation:

Since we have given that

Number of major recording acts are able to play at the stadium = 10

Average profit margin for a concert = $175000

We need to find the amount that the stadium clear for all of these events combined

As we know the formula for "Average"

Average=\frac{\text{ Total sum}}{\text{ Number of recording acts }}\\\\175000=\frac{\text{total sum}}{10}\\\\175000\times 10=Total\ sum\\\\\$1750000=Total\ sum

Hence, total amount the stadium would clear for all of these events combined is $1750000.

The probability of a train arriving on time and leaving on time is 0.8. The probability that the train arrives on time and leave
kkurt [141]

Answer:

<u>0.9524</u>

Step-by-step explanation:

<em>Note enough information is given in this problem. I will do a similar problem like this. The problem is:</em>

<em>The Probability of a train arriving on time and leaving on time is 0.8.The probability of the same train arriving on time is 0.84. The probability of the same train leaving on time is 0.86.Given the train arrived on time, what is the probability it will leave on time?</em>

<em />

<u>Solution:</u>

This is conditional probability.

Given:

  • Probability train arrive on time and leave on time = 0.8
  • Probability train arrive on time = 0.84
  • Probability train leave on time = 0.86

Now, according to conditional probability formula, we can write:

P(Leave \ on \  time | arrive \  on \ time) = P(arrive ∩ leave) / P(arrive)

Arrive ∩ leave means probability of arriving AND leaving on time, that is given as "0.8"

and

P(arrive) means probability arriving on time given as 0.84, so:

0.8/0.84 = <u>0.9524</u>

<u></u>

<u>This is the answer.</u>
