A 100-gallon fish tank fills at a rate of x gallons per minute. The function is F(x)=100/x. if the tank has been filling for 20
mixer [17]
The second graph is correct.

There will be a vertical asymptote at x=0, since we cannot divide by 0.  Using the x-axis on the second graph, if we substitute 5 in for x, we have 100/5+20 = 20+20=40.  There is a point on this graph here.  Using 10 for x, we have 100/10+20 = 10+20 = 30.  There is a point on the graph here.  Every point matches.

Write the equation of a line whose slope is 2/3 and crosses the y axis at (0, -5)
postnew [5]

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:

y=\frac{2}{3}x-5

Step-by-step explanation:

We will use the slope intercept form of the equation to make an equation of the given line

The slope-intercept form is:

y=mx+b

Here m is the slope and b is the y-intercept

Given

m = 2/3

Putting the value of slope

y=\frac{2}{3}x+b

The y intercept is -5 so we will put in the equation

y=\frac{2}{3}x-5

The equation of line with slope 2/3 and crosses the y axis at (0, -5) is:

y=\frac{2}{3}x-5

Keywords: Equation of line, slope-intercept form

Which of the following correctly relates the measures of the measures of the measures of the diameter (d) and radius (r) of a ci
yaroslaw [1]

Hey!

Diameter is ½ of the radius. To find the radius when you have the diameter, divide by 2.

For example, if the diameter is 12, the the radius would be:

12 \div 2 = 6

<em>That means your answer will be C.</em>

\framebox{Answer is C) r = d/2}

The average life of a certain type of small motor is 10 years with a standard deviation of 2 years. The manufacturer replaces fr
taurus [48]

Answer:

A guarantee of 6.24 years should be offered.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 10, \sigma = 2

If she is willing to replace only 3% of the motors that fail, how long a guarantee should be offered?

The 3rd percentile, that is, the value of X when Z has a pvalue of 0.03. So X when Z = -1.88.

Z = \frac{X - \mu}{\sigma}

-1.88 = \frac{X - 10}{2}

X - 10 = -1.88*2

X = 6.24

A guarantee of 6.24 years should be offered.
