Answer:

For this problem you will be multiplying 3 probabilities together: P(#1 is blue)*P(#2 is blue)*P(#3 is blue). For the first probability, we just need to divide the number of blue marbles by the total number of marbles which would be 8/18. For the 2nd probability, we need to remember that we have already removed 1 blue marble so that the number of blue marbles remaining is now 7 and the total number of marbles is now 17 to give us 7/17. We would repeat this process to get the third probability and then multiply all the probabilities together.

Answer:

  14.  53.1°

  16.  253.7°

Step-by-step explanation:

14. The measure of angle L can be found from the cosine relation:

  Cos = Adjacent/Hypotenuse

  cos(L) = 9/15 = 3/5

  L = arccos(3/5) = 53.1° . . . arc MK

__

16. Arc MK is half of arc JK, so that arc is 106.3°. The long arc JPK is the difference between 360° and the measure of the short arc JK.

  360° -106.3° = 253.7° . . . arc JPK

Answer:

3

Step-by-step explanation:

3 occurs the most in this data set

Answer:

The mode is 3.

Step-by-step explanation:

Presumably, x is standing in for the question mark.

The pair of vertical angles (DFE and CFV) shown here both have measure 125°. This angle measure is equal to the average of the measures of the arcs intercepted by the chords CE and DV.

So we have

angle DFE = 1/2 (arc CV + arc DE)

125° = 1/2 (x + 200°)

250° = x + 200°

x = 50°

Answer:

Bueno esto es lo que yo calculo

3×‐12

3(×‐4)

3 14x12

A calcule

A 12×3 =14

es lo que me calcula

Answer:

Step-by-step explanation:

14/6 = 21 / 3x - 12            

first, cross multiply

14 (3x - 12) = 6*21

Remove the brackets

42x - 168 = 126

Add 168 to both sides

42x = 168 + 126

Combine

42x = 294

Divide by 42

x = 294/42

x = 7

20x^2+23x+6

Step-by-step explanation:

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

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

20x^2+8x+15x+6

20x^2+23x+6

Hope that helps :)

Answer:

20x^2 + 23x + 6

Step-by-step explanation:

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

20x^2 + 8x + 15x + 6

20x^2 + 23x + 6

Answer:

a) 100

b) 7

Step-by-step explanation:

Remember that angle measurements correspond to side lengths. This also means that if two sides or angles are congruent, then the angle or side opposite of them will also be congruent. For example, in part a two sides are both 6. This means that the angles opposite of them are also both 40. Finally, to find <K subtract 80 (because that is 40+40) from 180. Therefore, the answer is 100 degrees.

Next, remember that the markings on the angles in part b mean that the angles are congruent. Since all the angles are congruent, the sides must be as well. So HI=7.

Answer:

x+y+z=15

x+2y+5z=15

-x+y+z=1

Step-by-step explanation:

Answer:

The answer is

x + y + z = 15

x + 2y + 5z = 35

-x + y + z = 1

Answer:

y=x^2

Step-by-step explanation:

Answer:

We know that for a human body 9.3% of its total mass is hydrogen.

Now we have a person with a mass of 140 lb.

Then we have that the 100% of the mass is 140lb, the 9.3% of this is hydrogen.

We can write:

9.3% = X

100% = 140lb

We want to find the value of X (mass of hydrogen)

Then we can take the quotient of these two equations to get:

(9.3%/100%) = X/140lb

Now we can isolate the variable X to get:

(9.3%/100%)*140lb = X = 13.02 lb

So this person has about 13.02 lb of hydrogen in his/hers body.

Answer:

  step 2; misapplication of the distributive property

Step-by-step explanation:

To eliminate parentheses, the distributive property of multiplication over addition tells you the outside factor is applied to each of the terms inside. The second step should be ...

  Step 2: (0.5)(4) +(0.5)(1.2x) +(0.5)(-3.1) = 2 +0.6x -1.55

Shane's mistake was that he added the factor to the first term, subtracted the factor from the coefficient of the second term, and added the factor to the third term. He was inconsistent even in his misapplication of the distributive property.

Answer:

Apparently that's false because 4 does not equal -1, 4 is totally 10 times greater than -1
