Answer:

6 combinations with a sample space of {DMC,DCM,CMD,CDM,MCD,MDC}

Step-by-step explanation:

Here, we are looking for the possible combinations of books since the order doesn't matter:

Method 1: You can take the factorial of 3 since order doesn't matter, which will mean 3!=3*2*1=6 combinations

Method 2: List all the possible combinations for your sample space

DMC

DCM

CMD

CDM

MCD

MDC

Either method you choose, you'll end up with the same result of 6 combinations with a sample space of {DMC,DCM,CMD,CDM,MCD,MDC}

What is the fewest number of people surveyed if exactly 93.6% of people completed a survey?
Use the whole numbers 0 through 9, at most one time, to fill in the boxes to create an accurate
number line.

Answers

Answer:

Step-by-step explanation:

7

the fewest number of people surveyed is 125, i’ll explain why.

the percentage of people that finished the survey is 93.6%, given.

this percentage as a fraction is p, (being the people) = 93.6/100, so, p = 93.6/100.

you then multiple the fraction 93.6/100 by 10, which is: p = 936/1000. then, reduce the fraction.

p = 117/125.

the fraction can’t be reduced any further, so that’s your answer.

27 Cm² (C)

...............

Answer:  Choice C.   27 cm^2

==========================================================

Explanation:

It's not directly stated, but I'm assuming that there's symmetry going on in terms of the triangle on the left being a mirror copy of the triangle on the right. If that assumption is true, then we have another "3 cm" along the bottom edge. In total, the bottom edge is 3+6+3 = 12 cm long.

The top edge, parallel to the bottom one, is 6 cm. We'll denote the two parallel sides to be the base lengths and we could write [tex]b_1 = 6 \text{ and } b_2 = 12[/tex]. The small subscript just helps us differentiate between the two base lengths.

The height is the vertical dashed line of 3 cm. This means h = 3. The height is always perpendicular to the base.

We'll plug those three variables into the area of a trapezoid formula below

[tex]A = \frac{h*(b_1+b_2)}{2}\\\\A = \frac{3*(6+12)}{2}\\\\A = \frac{3*(18)}{2}\\\\A = \frac{54}{2}\\\\A = 27\\\\[/tex]

The area is 27 square cm

-----------------------------------

Another way to get the answer is to break the trapezoid into three pieces: two triangles and a rectangle in between.

One triangle has an area of base*height/2 = 3*3/2 = 9/2 = 4.5 square cm, which means two triangles combine to an area of 2*4.5 = 9 square cm.

The rectangle has area of length*width = 6*3 = 18 cm^2

The trapezoid's area is the combination of what we found: 9+18 = 27 cm^2

Solve for x.

x=−19/6 ​

x=−11/6 ​ ​

x=21/6 ​

x=29/6

Answers

Answer:

X = 11/6

Step-by-step explanation:

Answer:

b) x = -11/6

Step-by-step explanation:

Given equation,

→ (-2/3)(3x - 4) + 3x = 5/6

Now the value of x will be,

→ (-2/3)(3x - 4) + 3x = 5/6

→ (-6x + 8)/3 + 3x = 5/6

→ (-6x + 8 + 9x)/3 = 5/6

→ -6x + 8 + 9x = (5/6) × 3

→ 3x + 8 = 5/2

→ 3x = (5/2) - 8

→ x = (-11/2) × (1/3)

→ [ x = -11/6 ]

Hence, value of x is -11/6.

Answer:

A. The constant ratio of y/x is 12/5

Step-by-step explanation:

The ratio of y to x is constant which is 12/5. Hence option A is the correct option.

What is a constant?

The term "constant" has several meanings in mathematics. When used as a noun, it can have any of the following two meanings:  a constant, clearly defined number or another immutable mathematical object.

Given table is

x                 y

5/6             2

25/6          10

125/6        50

625/6      250

When x = 5/6 and y = 2:

x/y = (5/6)/2 = 5/12

∴y/x = 5/12

When x = 25/6 and y = 10:

x/y = (25/6)/10 = 25/60 = 5/12

∴y/x = 5/12

When x = 125/6 and y = 50:

x/y = (125/6)/50 = 125/300 = 5/12

∴y/x = 5/12

When x = 625/6 and y = 250:

x/y = (625/6)/250 = 625/1800 = 5/12

∴y/x = 5/12
