Mean of the number of adults (out of the sample of 38) with blood type b- positive (x) is 3.04

Let x be the number of adults out of 38 with blood type b-positive

Probability, p of adults with blood type b-positive=8%=0.08

Sample size, n=38

Using binomial random variable x binomial(n=38, p=0.08)

p(X=x)=[tex]\left \ ({{n} \atop {x}}) \right. p^{x} q^{n-x}[/tex], where x=0,1,2,3,.....n

Mean of x:

Mean of x=(probability of adults with blood type b-positive*sample size)

So, mean of x=p*n, where n=38, p=0.08

                    =0.08*38

Similarity Theorems

Triangles ABG and DCB are similar by the AA similarity postulate

"If two angles in one triangle are congruent to two angles in another triangle, then the two triangles are similar"

The steps previous to statement 7 prove angles C and B are congruent because they are formed by two parallel lines that intersect a common line.

On the other side, angles DBC and AGB are congruent also because they are both right angles.

With two corresponding congruent angles, the AA similarity postulate is satisfied and the triangles are similar.

Outward journey Speed = 20 km/hr , James stopped for  45  Mins  ,Average speed homewars 15 km/hr

What is speed, for instance?

From graph  Journey Started at 2PM

on 3PM  James covered 20 km

Hence Speed =  (20 - 0)/(3 -2) = 20 km/hr

outward journey Speed = 20 km/hr

Now outward Distance = 45 km

Time taken = 45/20 = 2 hr 15 min

Hence reached at 4 : 15 PM

Started home at 5 PM

James stopped for  45  Mins  (3/4 hrs)

Reached back at 8PM

time taken = 8 - 5 = 3 Hrs

Distance = 45 km

Average speed homeward = 45/3 = 15 km/hr

Average speed homeward =  15 km/hr

The slope of the line is represented by the word m which is obtained as 0.5.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

To determine a line's inclination or steepness, use the slope formula. Calculating the ratio of the change in the y-axis to the change in the x-axis may be used to calculate the slope of any line.

From the graph, the data is observed as,

(x₁,y₁)=(0,1)

(x₂,y₂) = (-2,0)

The slope of the line is found as,

[tex]\rm m =\dfrac{0-1}{-2-0} \\\\ m = 0.5[/tex]

Thus, the slope of the line is represented by the word m which is obtained as 0.5.

Use the second option to write this expression as input.

Simplify both sides of the inequality.

Subtract 3x from both sides.

Subtract 6 from both sides.

[tex]\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{0 < -27} \end{gathered}$} }[/tex]

Answer:

0 < - 27

Step-by-step explanation:

1. Distribute

3x + 6 < 3(x-7)

3x + 6 < 3x - 21

2. Subtract 6 from both sides

3x + 6 <  3x - 21

3x + 6 - 6 < 3x - 21 - 6

3. Simplify

   subtract

    3x + 6 - 6 < 3x - 21 - 6

    3x <  3x - 21 - 6

   subtract

     3x < 3x - 21 - 6

     3x < 3x - 27

4. Subtract 3x from both sides

3x < 3x - 27

3x - 3x < 3x - 27 - 3x

5. Simplify

    combine like terms

     3x - 3x < 3x - 27 - 3x

     0 < 3x - 27 - 3x

     0 < 3x - 27 - 3x

      0 < -  27

The equations with same value of x as (3/5)(30x - 15) = 72 is 18x - 9 = 72, 3(6x - 3) = 72 and x = 4.5

An equation shows the relationship between two or more numbers and variables.

Given the equation:

(3/5)(30x - 15) = 72

Opening the parenthesis:

18x - 9 = 72

Factorizing the equation:

3(6x - 3) = 72

Dividing through by 3:

6x - 3 = 24

6x = 27

Dividing through by 6:

x = 4.5

The solution to the equation (3/5)(30x - 15) = 72 yields x = 4.5

Answer:

x = 4 , x = 2.4

Step-by-step explanation:

[tex]\frac{4}{x-2}[/tex] + [tex]\frac{3}{x-3}[/tex] = 5

multiply through by (x - 2)(x - 3)

4(x - 3) + 3(x - 2) = 5(x - 2)(x - 3)

4x - 12 + 3x - 6 = 5(x² - 5x + 6)

7x - 18 = 5x² - 25x + 30 ( subtract 7x - 18 from both sides )

0 = 5x²  - 32x + 48

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × 48 = 240 and sum = - 32

the factors are - 20 and - 12

use these factors to split the x- term

0 = 5x² - 20x - 12x + 48 ( factor the first/second and third/fourth terms )

0 = 5x(x - 4) - 12(x - 4) ← factor out (x - 4) from each term

0 = (x - 4)(5x - 12)

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

5x - 12 = 0 ⇒ 5x = 12 ⇒ x = 2.4

Answer: 2

Step-by-step explanation: 12 divided by 3 is 4 so 6 divided by 3 would be 2

⇒I will use the similarity theorem which works by proportion of sides in similar shapes.

⇒The side with magnitude 12 in the bigger triangle is proportional with the  side with magnitude 4 in the  smaller triangle

⇒The side with magnitude 6 in the bigger triangle is proportional with the side with magnitude x in the smaller triangle. The proportionality theorem allows us to equalize the proportions of the sides

⇒HOW? HERE it is the solution

⇒[tex]\frac{12}{4} =\frac{6}{x} \\[/tex]

⇒[tex]12(x)=4(6)\\12x=24\\\frac{1x}{12} =\frac{24}{12} \\x=2[/tex]

⇒I used cross multiplication

Answer:

A: Common multiple of 4 and 6 is 24

B: They would both be common multiples but they are two different multiples of 4 and 6.

C: 3/4= 18/24    1/6= 4/24

Step-by-step explanation:

A common multiple is a number that two numbers can be multiplied to. Something that both 4 and 6 can be multiplied to is 24, but there are many other multiples of 4 and 6  as well.
