Answer:41.7

Step-by-step explanation:let the unknown percent be x

X\100 of 48=20

X/100 x 48 =20

48x/100= 20

Cross multiply

48x =100 x 20

48x = 2000

Divide both sides by 48

X= 2000/48

X= 41.7

Which statements could he include in his explanation? select two options. the domain of both functions is all real numbers. the

mina [271]

The correct option is 'The domain of both functions is all real numbers'.

According to statement

Here, functions are f(x) = 5x and g(x) =5x

Since the domain of f(x) is, D= { x : x belongs to all real numbers.}

Therefore, Domain of f(x) is all real numbers.

Since f(x) and g(x) have the same value,

Therefore, Domain of g(x) is also the set of real numbers.

Now, range of f(x) is , R= { 5x : x belongs to all real numbers.}

Therefore, Range of f(x) is all real numbers.

Range of g(x) is also all real numbers.

So, we can say by the above explanation, only option (1) is correct.

A manufacturer of industrial solvent guarantees its customers that each drum of solvent they ship out contains at least 100 lbs

vekshin1

Answer:

The answer is "0.6368 and 0.773".

Step-by-step explanation:

The manufacturer of organic compounds guarantees that its clients have at least 100 lbs. of solvent in every fluid drum they deliver. $X\ is\ N(101.8, 3.76)\\\\P(X>100) =P(Z> \frac{100-101.8}{3.76}=P(Z>-0.47))$

For point a:

Therefore the Probability =0.6368

For point b:

$P(Z\geq \frac{100-101.8}{\sigma})=0.99\\\\P(Z\geq \frac{-1.8}{\sigma})=0.99\\\\1-P(Z< \frac{-1.8}{\sigma})=0.99\\\\P(Z< \frac{-1.8}{\sigma})=0.01\\\\z-value =0.01\\\\area=-2.33\\\\ \frac{-1.8}{\sigma}=-2.33\\\\ \sigma= \frac{-1.8}{-2.33}=0.773$

How do you do this problem?

Kay [80]

d + q = 35....d = 35 - q
0.10d + 0.25q = 7.25

0.10(35 - q) + 0.25q = 7.25
3.50 - 0.10q + 0.25q = 7.25
-0.10q + 0.25q = 7.25 - 3.50
0.15q = 3.75
q = 3.75/0.15
q = 25

d + q = 35
d + 25 = 35
d = 35 - 25
d = 10

so there are 25 quarters and 10 dimes

What is the equation of the line that passes through (4,-1) and (-2,3)

german

<h2>Hello!</h2>

The answer is:

The second option

$2x+3y-5=0$

To know which is the equation of the line, we need to follow the next steps:

Find the slope of the line:

We are given the points:

$(-2,3)\\(4,1)$

Where,

$x_1=4\\y_1=-1\\x_2=-2\\y_2=3$

Also, we know that we can calculate the slope of a function using the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Now, using the slope formula, and substituting the given points, we have:

$m=\frac{3-(-1)}{-2-4}$

$m=\frac{4}{-6}$

$m=-\frac{2}{3}$

Find the "b" value:

In order to find "b" we need to substitute any of the given points, we know that line pass through both of the given points, so, substituting the point (4,-1), we have:

Writing the slope form of the function,

$y=mx+b$
