The first fraction is 7/10.
The second bag has the same probability as the top so just copy the fractions into the boxes.
To calculate the probability of the same colour being chosen you follow these steps.
P(RR) = 3/10 x 4/9 = 12/90
P(GG) = 7/10 x 5/9 = 35/90
Then add the two fractions.
12/90 + 35/90 = 47/90
The last box is 47/90.

Which of the following is a solution to the inequality below?

kap26 [50]

Answer:

V>-8

Step-by-step explanation:

The given inequality is :

4-V>12

Subtracting 4 from both sides.

4-V-4 > 12-4

-V>8

or

V>-8

So, the value of V is more than -8.

quester [9]

Answer:1866

Step-by-step explanation:

Given

n=200

x=118

Population proportion P= $\frac{118}{200}$ =0.59

$\alpha$ =0.005

Realiability =99%

$Z_{\frac{\alpha }{2}}=2.576$

Margin of erroe is given by $\sqrt{\frac{p\left ( 1-p \right )}{N}}$

0.03= $\sqrt{\frac{0.59\left ( 1-0.59 \right )}{N}}$

85.667= $\sqrt{\frac{N}{0.6519}}[tex]N=1865.88[tex]\approx 1866 Students$

Give the excluded values for the rational equation.<br><br> (3x)/(x-4)-(x+3)/(x+4)=(2x+7)/(x^(2)-16)

scoray [572]

$\frac{3x}{x-4} - \frac{x+3}{x-4} = \frac{2x+7}{x^2-16}$

We factor the denominators

Factor x^2 - 16

x^2 - 4^2

We use a^2 - b^2 = (a+b)(a-b)

so x^2 - 4^2 = (x+4)(x-4)

Replace it in the given equation

$\frac{3x}{x-4} - \frac{x+3}{x-4} = \frac{2x+7}{(x+4)(x-4)}$

Excluded values are the values that makes the denominator 0

we have (x-4) and (x+4) in the denominator

We set the denominator =0 and solve for x

x-4 =0

Add 4 on both sides

x= 4

x+4=0

subtract 4 onboth side

so x= -4

Excluded values are x=-4 and x=4

Drag each measure to a box on the right to match the measure on the left. 5 feet10,560 feet48 inches126 inches 2 miles 123 yards

charle [14.2K]

Answer:

4 feets = 48 inches

2 miles = 10,560 feets

1 2/3 yards = 5 feets

3 1/2 yards = 126 inches

Step-by-step explanation:

Recall :

1 Feet = 12 inches

1 MILE = 5280 feets

1 yard = 36 inches

1 yard = 3 feets

If 1 feet = 12 inches

4 feets will be ; (12 * 4) inches = 48 inches

If 1 mile = 5280 feets

2 miles will be ; (5280 * 2) = 10,560 feets

If 1 yard = 3 feets

1 2/3 yards will be ; (5 /3) * 3 = 5 feets

If 1 yard = 36 inches

3 1/2 yards will be ; (7 /2 ) * 36 = 126 inches
