Water Tank A is being filled according to the formula, 3y=750x+300.

Answer: All the time.

Step-by-step explanation:

Here,

x= elapsed time

y = number of gallons of water in tank.

For tank A,

3y=750x+300

Divide both sides by 3, we get

y= 250x+100 ...(i)

For tank B,

4y=1000x+400

Divide both sides by 4, we get

y=250+100 ...(ii)

From (i) and (ii) it can be seen that both the function are same.

That means the amount of watre will be same for every value of x, where x ≥0

Answer:

<h2>12x−3</h2>

Step-by-step explanation:

Let's simplify step-by-step.

10x+6+2x−9

=10x+6+2x+−9

Combine Like Terms:

=10x+6+2x+−9

=(10x+2x)+(6+−9)

=12x+−3

Answer:

=12x−3

Use the work shown below to write the equation for a line that passes through the points (−5, 0) and (−1, −8).
Dennis_Churaev [7]

Answer:

M = -2

b = -10

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

m = (-8 -0)/(-1- -5)

   = (-8-0)/(-1+5)

    = -8/4

    = -2

We now want to find the y intercept

y = mx+b is the slope intercept form of the equation

y = -2x+b

Using the point (-5,0)

0 = -2(-5) +b

0 = 10+b

Subtract 10 from each side

-10 = 10-10+b

-10 =b

The y intercept is -10

y= -2x-10

Suppose that a standardized biology exam has a mean score of 80% correct, with a standard deviation of 3. The school administrat
NemiM [27]

Answer:

The 99% confidence interval is between 62.36%(lower bound) and 89.64%(upper bound).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

A sample of 65 students from the freshmen class is used and a mean score of 76% correct is obtained.

This means that n = 65, \pi = 0.76

99% confidence level

So \alpha = 0.005, z is the value of Z that has a pvalue of 1 - \frac{0.005}{2} = 0.995, so Z = 2.575.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.76 - 2.575\sqrt{\frac{0.76*0.24}{65}} = 0.6236

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.76 + 2.575\sqrt{\frac{0.76*0.24}{65}} = 0.8964

0.6236*100 = 62.36%

0.8964*100 = 89.64%

The 99% confidence interval is between 62.36%(lower bound) and 89.64%(upper bound).
