a mixture of medicine consists of three vitamins A, B and C,if the ratio of the vitamins should be 5:1:3 and the total mixture is 40 ml calculate how much of each vitamin will be needed for the final mixture​

Answer:

The mean is 30

Step-by-step explanation:

To find the mean you add up all the numbers then divide how many numbers there are.....

10+20+30+40+50=150

150/5= 30

Answer:

25/208 or 12.2%

Step-by-step explanation:

P(heart) = 13/52 = 1/4

P(red) = 26/52 = 1/2

because we are not replacing the first card drawn, the deck has 51 cards remaining

P(heart, red) = 1/4 × 25/52

= 25/208 or 12.2%

Answer:

203 m

Step-by-step explanation:

Set up a proportion and solve it.

drawing size     :     real size

      14 cm          :           x

       2 cm          :          29 m

14/x = 2/29

2x = 14 × 29

x = 7 × 29

x = 203

          The value of x in the algebraic expression is -2.5

An algebraic expression is the representation of numbers with variables with the purpose of solving for the variable. The variables are expressed by using alphabetical letters, here it is (x).

From the given algebraic expression, we have:

4x + 2 = -8

Collect like terms

4x = -8 - 2

4x = - 10

Divide both sides by 4

[tex]\mathbf{\dfrac{4x}{4} = \dfrac{-10}{4}}[/tex]

x = -2.5

Answer:

x - 2

Step-by-step explanation:

If (x - h) is a factor of f(x) then f(h) = 0

Here f(2) = 0 , then x - 2 is a factor of f(x)

Using the hypergeometric distribution, it is found that there is a 0.4286 = 42.86% probability of getting 2 of the same colour.

The marbles are chosen without replacement, hence the hypergeometric distribution is used to solve this question.

The formula is:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability of getting 2 of the same colour is the sum of P(X = 0), which is both red, with P(X = 2), which is both blue, then:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 0) = h(0,7,2,3) = \frac{C_{3,0}C_{4,2}}{C_{7,2}} = 0.2857[/tex]

[tex]P(X = 2) = h(2,7,2,3) = \frac{C_{3,2}C_{4,0}}{C_{7,2}} = 0.1429[/tex]

Hence:

[tex]p = P(X = 0) + P(X = 2) = 0.2857 + 0.1429 = 0.4286[/tex]

0.4286 = 42.86% probability of getting 2 of the same colour.

f(x) = g(x) at 0 and 1.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

Given

 x                         f(x) = [tex]\rm 3^x[/tex]                   g(x) = 2x + 1

-2                             [tex]\frac{1}{9}[/tex]                                 -3

-1                              [tex]\frac{1}{3}[/tex]                                 -1

0                              1                                  1

2                              9                                 5

The solution to f(x)=g(x).

It is clear that at x = 0 and 1, f(x) = g(x).

Thus, f(x) = g(x) at 0 and 1.

Answer:

9

Step-by-step explanation:

Since you have a right triangle, you can use the Pythagorean theorem.

a² + b² = c²

x² + 5² = 10²

x² + 25 = 100

x² = 75

x = √75

x = 5√3 = 8.66...
