Pealed solve and explain.

Answer:

The correct answer is B :)

Step-by-step explanation:

The number of k-combinations(5) from a given set S of n (24) elements

Calculating the number of combinations

Substituting our values for n= 24 and k= 5 we get

24C5 = 24!5!(24−5)!

Subtracting 5 from 24 is 19

24!5!(19)!

Expending factorial

24X23X22X21X20X19!(5X4X3X2X1)X19!

Cancelling common factors

24X23X22X21X205X4X3X2X1

Multiply numerator values and denominator values

5100480120

Divide the 5100480 by 120

Final Result :42504.0

There are 42504.0 combinations to choose 5 items out of a set of 24

Answer:

6.25%

Step-by-step explanation:

Each time you flip a coin, there is a 50% probability of it landing on tails. Each time you flip the coin, the 50% gets multiplied by [tex]\frac{1}{2}[/tex].

[tex]\frac{1}{2}[/tex] to the power of 4 is 0.0625. 0.0625 in percentage form is of course 6.25%

Answer:

EC, DE, CD

Step-by-step explanation:

∠D=34°    ∠C=47°     ∠E= 180-34-47=99°

∠D < ∠C < ∠E

By the theorem: If one angle in a triangle is larger than another angle in a triangle, then the side opposite the larger angle will be longer than the side opposite the smaller angle.

EC < DE < CD

Answer:

Rs.12500

Step-by-step explanation:

18% = saved

100 - 18 = 82%(used salary)

82% = 10250

100% = ?

100 × 10250 = 1025000

1025000 ÷ 82 = Rs.12500

Answer:

its the third answer

Step-by-step explanation:

The third anwser is 66% which we can noow nominate any lower.

The second answer is 60% we can get rid of that.

the first is 55% we can get rid of that.

and the fourth is 62.5% so we can get rid of that.

Answer:

the third one or c

Step-by-step explanation:

Answer: -24

Step-by-step explanation:

[tex]\frac{x}{6} -18 = -22[/tex]

[tex]\frac{x}{6} = -22 + 18[/tex]

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

[tex]x= -4*6[/tex]

[tex]x= -24[/tex]

check work

[tex]\frac{(-24)}{6} -18 = -22[/tex]

[tex]-4 -18 = -22[/tex]

[tex]-22 = -22[/tex]

Answer:

The question is not written correctly (and I couldn't find the actual question online), I assume that the actual question is:

"Angles A and B are complementary. If mL A = 2*x + 43 and mL B = 47°. Solve for x to find the measure of L A."

So I can answer this in a step by step way:

First, two angles are complementary if the sum of their measures is equal to 90°

Then we must have:

mL A +  mL B = 90°

If we replace these by the measures, we have:

2*x + 43° +  47° = 90°

Now we can solve this for x.

2*x + 90° = 90°

2*x = 90° - 90° = 0°

Then we must have x = 0°.

Y = x^2 - 2x - 15

Step-by-step explanation:

Answer:

4.32

Step-by-step explanation:

First, we have to find the mean of the data set.

16, 11, 9, 12, 11, 10, 10, 8, 15, 0, 2, 15, 14, 7, 11, 5, 14, 20, 3, 11, 13, 7, 0, 5, 21 all added together equals 250. 250 divided by 25 = 10. So 10 is the mean.

Now we have to find the absolute distances of each number from the mean.

16 - 10 = 6... 11 - 10 = 1... so on, giving us this -->

6, 1, 1, 2, 1, 0, 0, 2, 5, 10, 8, 5, 4, 3, 1, 5, 4, 10, 7, 1, 3, 3, 10, 5, 11

Finally, we have to find the mean of the distances (which is done by adding all the numbers above and dividing the sum by the number of values there are).

108 divided by 25 = 4.32.

So, 4.32 is the mean absolute deviation (MAD) of the following data set.

Answer:

Step-by-step explanation:

[tex]\sqrt{x-3}[/tex] = x - 5 ( x ≥ 3 )

( [tex]\sqrt{x-3}[/tex] )² = ( x - 5 )²

x - 3 = x² - 10x + 25

x² - 11x + 28 = 0

(x - 4)(x - 7) = 0

[tex]x_{1}[/tex] = 7

[tex]x_{2}[/tex] = 4

Check the answer:

1). x = 7

[tex]\sqrt{7-3}[/tex] = 7 - 2

√4 = 2

2 = 2

2). x = 4

[tex]\sqrt{4-3}[/tex] = 4 - 5

1 = - 1 (False statement) ⇒ x = 4 is an extraneous solution.

Answer:

430 cm squared

Step-by-step explanation:

SA= 2(Length x Base, Base x Height, Height x Length)

15cm x 5cm +

15cm x 7xm +

7cm x 15cm =

215cm

215cm x 2 = 430 cm squared.

(it's perimeter of a 3D object so it must be squared, then volume would be cubed)

Answer:

52√3 ft²

Step-by-step explanation:

sin 60° = (√3) / 2 = h/8

h = 8 x (√3) / 2 = 4√3

cos 60° = 1/2 = a/8

a = 4         b = 15-4 = 11

area = left triangle + right rectangle

area = (4*4√3) / 2 + 11*4√3

        = 8√3 + 44√3

        = 52√3

Answer:

18 children weighed less than 50 pounds.

Step-by-step explanation:

Ok, adding into the explanation what the heck this kind of a table is. The "stem" column is the tens place of each of the children's weights. The "leaf" is the ones digit of each of the children's weights. So in the row where the stem is 2, there were 2 kids weighing 23 and 25 pounds.

For your question, we have to add up how many students have a weight with a "stem" less than 5, because that's where 50 pounds starts.

8 + 2 + 5 + 3 = 18 children weighed less than 50 pounds.

It is assumed the base of the prism is a square wit side of 5 cm.

The volume is:

V = Bh = 250 cm³

The base is:

B = a² = 5² = 25 cm²

Find h:
