Answer:

(number - mean)/standard deviation.

Plug in the 78 for the number, the 84.5 for the mean, the 3.1 for the standard deviation.

I really dont know how to start this Calculus 1 question!

hichkok12 [17]

According to the given plot, $f'(1)=2$ . Then the linear approximation to $f(x)$ at $x=1$ is

$L(x)=f(1)+f'(1)(x-1)=6+2(x-1)=2x+4$

Then

$f(0.95)\approx L(0.95)=5.9$

$f(1.05)\approx L(1.05)=6.1$

On the interval [0, 1], the plot of $f'(x)$ is positive, so $f(x)$ is an increasing function here. But we can see that $f'(x)$ is approaching 0. This means tangent lines to $f(x)$ have a positive slope, but the slopes are approaching 0 and are thus becoming less steep. This in turn means the tangent lines lie above the curve, so the approximations are greater than the actual values of $f(0.95)$ and $f(1.05)$ .

Please help! 25 points!<br> Write the equation of a line with slope 3/2 and Y-Intercept -2.

Juli2301 [7.4K]

Hello there!

For this question, we can use slope-intercept form of a line. The following equation is the format for slope-intercept form:
$y=mx+b$

In this equation, m is the slope and b is the y-intercept. The slope and y-intercept is given. Thus, we just "plug in" the given values into the equation to get our answer. Replace "m" with "3/2" and replace "b" with "-2". After doing so, you get the following equation for the line.

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

That should be your answer. Hope this helps! :)

There are 620 people at a play. The admission price is $2 for adults and $1 for children. The receipts totalled $960.00. How man

romanna [79]

To get the answer, divide the receipts by 2 to get the total cost for adults and divide it again to get the total number of parents who attended

Cost for adults is $480.00
Number of adults is 240

Now, to get the children, subtract the total number of people by the number of adults.
620-240=380

Number of children is 380
