First find the equation of the given line. Let y=mx+b. 1=4m+b;-3=-4m+b. Solving, and get b=-1, m=1/2. So the line that is perpendicular to it must have slope -1/m=-2. Suppose the form is y=-2x+b, since it passes through (-4,3), the point slope form is y-3=-2(x+4).

A soft drink machine outputs a mean of 24 ounces per cup. The machine's output is normally distributed with a standard deviation
Arisa [49]

Answer:

P(21

And we can find the probability with this difference

P(-1

And using the normal standard distribution or excel we got:

P(-1

Step-by-step explanation:

Let X the random variable that represent the soft drink machine outputs of a population, and for this case we know the distribution for X is given by:

X \sim N(24,3)  

Where \mu=24 and \sigma=3

We want to find this probability:

P(21

The z score is given by:

z=\frac{x-\mu}{\sigma}

Using this formula we got:

P(21

And we can find the probability with this difference

P(-1

And using the normal standard distribution or excel we got:

P(-1

The pet doctor weighs Marc's dog every year. Last year, the dog lost 3.73 pounds from the previous year. This year, the dog gain
levacccp [35]

Answer:

-2.26 lb

Step-by-step explanation:

Let the dog's initial weight be d.

Then, one year later, the dog weighs 3.73 lb less, and thus weighed d - 3.73 lb.  

During the next year, the dog gained 1.47 lb, so now weighs d - 3.73 + 1.47 lb, or

d - 2.26 lb.  This indicates a total weight loss of 2.26 over these two years.

F(x)=x+7 and , g(x)=1/x-13 what is the domain of (f*g) (x) P L E A S E H E L P A S A P !
Kaylis [27]
The inner function g(x) has x-13 in the denominator. Set it equal to 0 and solve for x

x-13 = 0
x-13+13 = 0+13
x = 13

If x = 13 then the denominator of g(x) will be zero. This is a problem since you cannot divide by zero

So x = 13 is not allowed as an input in the g(x) function. The same applies for the composite function as well.

So that's why the domain is the set of all real numbers x but x cannot equal 13

This translates to what choice D is saying, so that is the answer
