Help, I really need help and I've been stuck on this one ^^^

Lostsunrise [7]

Hey there! :)

Let's put all of our facts down first. We know that slope-intercept form is y=mx+b , where m=slope & b is the y-intercept.

So, if we're given the slope and y-intercept, then we can very simply plug those values into slope-intercept form!

Our slope is 4 and our points are (0, -1).

y = mx + by = (4)x + (-1)

Get rid of our parenthesis.y = 4x - 1

So, our equation of the line that passes through (0, -1) and has a slope of 4 is y = 4x - 1

~Hope I helped!~

If f(x) = -4x + 2 and g(x) = sq root X – 8,<br>what is (fºg)(12)?

Anettt [7]

Answer:

$(fog)(12)=-6$

Step-by-step explanation:

Recall that the notation: $(fog)(12)$ is the same as: $f(g(12))$ which means the value of the function f when you give it as input the value obtained by evaluating g(12).

Therefore, we need to start finding what g(12) is using the definition :

$g(x)=\sqrt{x-8}$ and evaluating it as x = 12.

$g(x)=\sqrt{x-8}\\g(12)=\sqrt{12-8}\\g(12)=\sqrt{4}\\g(12)=2$

So now we use this answer "2" as input for f(x):

$f(x)=-4x+2\\f(2)=-4(2)+2\\f(2)=-8+2\\f(2)=-6$

Therefore, $(fog)(12)=-6$

A circle has a sector with area \dfrac{1}{2}\pi 2 1 πstart fraction, 1, divided by, 2, end fraction, pi and central angle of \

balu736 [363]

Answer:

Area of circle = 9<em>π</em>

Step-by-step explanation:

Area of sector = $\frac{1}{2} \pi$

Its central angle = $\frac{1}{9}\pi \text{ radians}$

$\text{Area of sector} = \dfrac{\text{Central angle}}{2\pi} \times\text{Area of circle}$

$\text{Area of circle} = \text{Area of sector}\times\dfrac{2\pi}{\text{Central angle}}$

$A = \dfrac{1}{2}\pi\times\dfrac{2\pi}{\frac{1}{9}\pi} = 9\pi$

Systolic Blood Pressure Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury and the stan

liq [111]

Answer:

0.1425 = 14.25% probability that the individual's pressure will be between 119.4 and 121.4mmHg.

Step-by-step explanation:

When the distribution is normal, we use 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 question, we have that:

$\mu = 120, \sigma = 5.6$

Find the probability that the individual's pressure will be between 119.4 and 121.4mmHg

This is the pvalue of Z when X = 121.4 subtracted by the pvalue of Z when X = 119.4. So

X = 121.4

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

$Z = \frac{121.4 - 120}{5.6}$

$Z = 0.25$

$Z = 0.25$ has a pvalue of 0.5987

X = 119.4

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

$Z = \frac{119.4 - 120}{5.6}$

$Z = -0.11$

$Z = -0.11$ has a pvalue of 0.4562

0.5987 - 0.4562 = 0.1425

0.1425 = 14.25% probability that the individual's pressure will be between 119.4 and 121.4mmHg.
