A bag contains 10 marbles: 2 are green, 4 are red, and 4 are blue. Tammy chooses a marble at random, and without putting it back, chooses another one at random. What is the probability that both marbles she chooses are blue?

Answer:

I believe the answer is 8 to 8 (8/8) or 1

Step-by-step explanation:

16-8=8

Wins= 8

Loses= 8

Ratio= 8/8

8/8= 1

The answer depends how the question asks for it, so its either 8 to 8, or 1

[tex]3(23+18) < 6a \\ 41 < 2a \\ a > 41/2\implies a > 20.5[/tex]

Hope this helps.

Answer: a >41/2

Step-by-step explanation: Step 1: Simplify both sides of the inequality.

123<6a

Step 2: Flip the equation.

6a>123

Step 3: Divide both sides by 6.

6a/6>123/6

a>41/2

Answer:

The expected frequency for the cell E2,2 is = 33

Step-by-step explanation:

The given data is

Gender               | 0-30| 30-60| 60-90| 90+       Totals

Male                    | 23    |    35   |   76    |  46        180

Female               |   31   |    42   |   46    |  16         135    

Totals                    54         77        122    62          315  

The expected frequency for the cell E2,2 is :

Expected for the (30-60 box for females)   =  Total of (30-6)/ (total )* females

                                                                      = ( 77/315)135= 33

Here p= 77/315 and n= 135

therefor X= pn = 33

χ²=  (33-42)²/33= 2.455  ( for the single value of E2,2=33)

Expected for the (30-60 box for males)   =  Total of (30-6)/ (total )* males

                                                                      = ( 77/315)180= 44

χ²=  (44-42)²/44= 0.09

The critical region is  χ² (0.05) 3 ≥  χ²= 11.34

Let the null and alternate hypothesis be

H0:the number of minutes spent online per day is not related to gender

against

Ha: the number of minutes spent online per day is related to gender

The single value of χ² for E2,2 = 2.45 is less than the critical value of 11.34.

142/596 ≅ 0.238 = 23.8%

[tex] \frac{142}{596} \times 100[/tex]

= 23.8255....

= 23.8%

Answer:1 ) x: 5.8 = 365

Step-by-step explanation:

x = 365 × 5.8

x = 2117

2117: 5.8 = 365

2) x: 8.4 = 2.3

x = 2.3 × 8.4

x = 19.32

19.32: 8.4 = 2.3

3) x: 8.1 = 0.15

x = 0.15 X 8.1

x = 1.215

1.215: 8.1 = 0.15

4) x: 0.22 = 4.9

x = 4.9 x 0.22

x = 1.078

1.078: 0.22 = 4.9

Answer:

z=13

Step-by-step explanation:

The sum of the two angles is 90 degrees

2z+5   + 5z-6  = 90

Combine like terms

7z-1 = 90

Add 1 to each side

7z-1+1 = 90+1

7z = 91

Divide each side by 7

7z/7 = 91/7

z =13

3/8*2/6=6/48

The solution of the expression 3/8 times 2/6 is,

⇒ 6/48

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The expression is,

⇒ 3/8 times 2/6

Now, We can simplify as;

⇒ 3/8 times 2/6

⇒ 3/8 × 2/6

⇒ 6/48

Thus, The solution of the expression 3/8 times 2/6 is,

⇒ 6/48

Answer:

son 2 sucesiones si ves u a va subiendo y otra ba bajando

Answer:

-6 a b + b + a

Step-by-step explanation:

Simplify the following:

-(a - b + a b) - a b - 4 a b + 2 b - 2 b + 3 a - a

Hint: | Group like terms in 3 a - 2 b - a b - (a b - b + a) - 4 a b + 2 b - a.

Grouping like terms, 3 a - 2 b - a b - (a b - b + a) - 4 a b + 2 b - a = -(a b - b + a) + (-a b - 4 a b) + (3 a - a) + (2 b - 2 b):

-(a b - b + a) + (-a b - 4 a b) + (3 a - a) + (2 b - 2 b)

Hint: | Combine like terms in -a b - 4 a b.

a b (-1) + a b (-4) = -5 a b:

-(a b - b + a) + -5 a b + (3 a - a) + (2 b - 2 b)

Hint: | Combine like terms in 3 a - a.

3 a - a = 2 a:

-(a b - b + a) - 5 a b + 2 a + (2 b - 2 b)

Hint: | Look for the difference of two identical terms.

2 b - 2 b = 0:

-(a b - b + a) - 5 a b + 2 a

Hint: | Distribute -1 over a b - b + a.

-(a b - b + a) = -a b + b - a:

-a b + b - a - 5 a b + 2 a

Hint: | Group like terms in -a b - 5 a b + b + 2 a - a.

Grouping like terms, -a b - 5 a b + b + 2 a - a = (-a b - 5 a b) + b + (-a + 2 a):

(-a b - 5 a b) + b + (-a + 2 a)

Hint: | Combine like terms in -a b - 5 a b.

a b (-1) + a b (-5) = -6 a b:

-6 a b + b + (2 a - a)

Hint: | Combine like terms in 2 a - a.

2 a - a = a:

Answer: -6 a b + b + a

392 ft^2

Step-by-step explanation:

area = length * width

a = lw

392 = 14 * 28

Don't forget the unit is ft^2 since we are finding the area of a 2-dimensional shape in feet!

Answer:

Step-by-step explanation:

the area of a rectangle is L*W

A=14*28=392 ft^2

Alright, sorry for possibly wasting the answer, but its either D or B. i think its D, because its a bisector of the line segment, but B reads that it IS perpendicular, but on points not the line. You can rule out which one of the two it is, i would suggest asking a teacher for help or waiting for a better and more reliable answer.

Answer:

x = 3  &&  y = - 1

Step-by-step explanation:

Just solving the two equations

the first equation

y = 4/3 x +3

y  - 4/3 x = 3  ..............................................(1)

the second equation

y = -2/3x -3

y + 2/3 x = -3  ..............................................(2)

by substracting 2 from 1

-4/3x - 2/3x = -6

divide by -1

4/3x +2/3x = 6

6/3x = 6

2x = 6

x= 3

then subsititute by value x in any of given eqautions  

Answer:

1.67square foot/hr

Step-by-step explanation:

If a fertilizer covers 5/6 square foot in 1/2 hour, then;

5/6 square foot  = 1/2 hour

To determine the unit rate, we will say;

x square foot = 1 hr

Divide both expressions

5/6x = 1/2

5 * 2 = 6x

10 = 6x

x = 10/6

x = 1.67square foot/hr

Hence the unit rate is 1.67square foot/hr
