knowing that concentration of solutions of medications can be expressed as percentage, what percentage is a solution that's 20g of medication per 100 ml solution?

Answer:

0.57

Step-by-step explanation:

Given that:

food = f ; c = clothes

P(f) = 0.76

P(C) = 0.49

P(fnC) = 0.28

Suppose a shopper is selected from the store at random and learn that they buy clothes. What is the probability that the shopper also buys food?

P(f Given C) = P(f | C)

P(f | c) = p(fnC) / p(C)

P(f | c) = 0.28 / 0.49

P(f | c) = 0.5714

P(f | c) = 0.57

Answer:

.57

guy above me is right

Step-by-step explanation:

Solution :

Here, [tex]$ \hat p$[/tex] = sample proportion of red outcomes

[tex]$ \hat p =\frac{58}{100}$[/tex]

[tex]$ \hat p$[/tex] = 0.58

So we have to test,

[tex]$H_0 : p = 0.5$[/tex]

V/S    [tex]$H_a: p \neq 0.5 $[/tex]

The test statistic is

[tex]$z = \frac{\hat p - p}{\sqrt{\frac{p(1-p)}{n}}}$[/tex]

[tex]$z = \frac{0.58 - 0.5}{\sqrt{\frac{0.5(1-0.5)}{100}}}$[/tex]

  [tex]$=\frac{0.08}{0.05}$[/tex]

  = 1.600

P value using the z table is 0.110

So P value greater than 0.05

Therefore, there is no evidence that roulette wheel is out of balance.

identity property okayyyyyyyy?

Answer:

Step-by-step explanation:

We want to  confirm which of the given statement is true about the graph.

A) the amount of profit after the first year was around $0

-----------false

From the given graph, the amount of profit after year was far more $0. So the statement above is false.

B) The amount of profit increases about $10,000 each year ------------true

From the line of best fit shown in the graph, the amount of profit increases each year  by approximately $10,000.

C) the amount of profit decrease about $10,000 each year ------------ False

From the line of best fit on the graph, we can observe that the amount of profit does not decrease. It rather increases every year.

D) the amount of profit after the first year was around $30,000 ------------true

From the given graph, the  amount of  profit after the  first year is approximately $30,000.

So, the statement is true.

E) the amount of profit after 10 years is approximately $120,000  --------- true

At the year 10 on the graph , the  corresponding amount of profit is $120,000.

Answer:

10 Gallons of water will weigh 1.2 pounds.

Step-by-step explanation:

Each gallon weighs 0.12 pounds, I got this answer from dividing 3 by 25 to see how much one gallon weighs. So if we multiply the weight of one gallon by 10, 0.12*10, then we will find out the weight of ten gallons.

I hope this helped you!! You can ask questions any question you may have, if needed, and I will answer them :)

10 Gallons of water will weigh 1.2 pounds.

Here, we have,

given that,

Morgan know that 3 gallons of water weigh 25 pounds.

now, we need to find how much do 10 gallons weigh.

so, we get,

3 gallons of water weigh 25 pounds.

so, to see how much one gallon weighs we divide 3 by 25 .

i.e. 3/25 = 0.12

Each gallon weighs 0.12 pounds,  

So if we multiply the weight of one gallon by 10,

i.e. 0.12*10, then we will find out the weight of ten gallons.

so, we get,

10 gallons weigh = 0.12*10 = 1.2 pounds.

Answer: x = 4

Step-by-step explanation:

Here we have a piecewise function.

One piece works for values of x such that:   -6 < x < 0

And the other piece works for values of x such that: 0 < x ≤ 4

Then the domain of this function is:

D = (-6, 0) U (0, 4]

Notice that, becuse we use the symbols ><, the values of x:

x = -6

x = 0

Do not belong to this domain.

While becuase we use the symbol ≤ in the right end, the value x = 4 does belong to the domain.

Then for the given options, the only value that belongs to the domain is the third option, x = 4.

Answer:

208

Step-by-step explanation:

Given that;

Given that;

y= a(1 - b)^t

Where;

wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.

To obtain the constant b,

y= ae^-bt

Substituting values;

1000 = 3000 e^-b(50)

1000/3000 = e^b(50)

0.33 = e^b-(50)

ln (0.33) = ln(e^b(-50))

-1.1 = -50b

b= 1.1/50

b= 0.022

After two hours or 120 minutes;

y= 3000(1 - 0.022)^120

y= 207.8661772

y= 208

Answer:

We get the value of x: x= 2

Step-by-step explanation:

Since the triangles are similar, the ratios of the lengths of corresponding sides are same.

We can use proportions to find the value of x

The proportion will be:

[tex]\frac{BD}{DA}=\frac{BE}{EC}[/tex]

Now putting there values we can find value of x

We have:

BD = 6, DA = 4, BE = x+1, EC =x

Putting values

[tex]\frac{BD}{DA}=\frac{BE}{EC}\\\frac{6}{4}=\frac{x+1}{x} \\Cross\:Multiply\\6x=4(x+1)\\6x=4x+4\\6x-4x=4x+4-4x\\2x=4\\x=\frac{4}{2}\\x=2[/tex]

So, we get the value of x: x= 2

Answer:

The measure of angle E is:

m∠E = 80°

Step-by-step explanation:

Given

The triangle ΔDEF

It is stated that DE=EF and G is the midpoint of EF.

It means the midpoint G has converted the triangle into two equal right-angles triangles ΔDEG and ΔDFG with the right-angle at G.

Given

m∠GDE = 10°

As the right-angle triangle, ΔDEG lies at the right-angle G.

So, m∠DGE = 90°

as

m∠GDE = 10°

m∠DGE = 90°

m∠E = ?

We know that the sum of angles of a triangle is 180°.

m∠GDE + m∠DGE  + m∠E = 180°

10° + 90° + m∠E = 180°

100 + m∠E = 180°

m∠E = 180° - 100

m∠E = 80°

Therefore,

The measure of angle E is: m∠E = 80°
