Elisa has 10 gold colored coins and 6 silver colored coins. She selects 2 coins with replacement. What is the probability she se

amm1812

Answer: $\frac{9}{64}$

Step-by-step explanation:

n(gold colored coins) = 10

n(silver colored coins) = 6

Total number of coins = 16

since there is replacement , the probability she selects 2 silver colored coins will be :

$\frac{6}{16}$ x $\frac{6}{16}$

= $\frac{3}{8}$ x $\frac{3}{8}$

= $\frac{9}{64}$

Therefore : the probability she selects 2 silver colored coins is $\frac{9}{64}$

What are the next 3 terms from the sequence Tn+1=Tn+3, T1=6

Brut [27]

Answer:

9, 12, 15

Step-by-step explanation:

Using the recursive formula and T₁ = 6 , then

T₂ = T₁ + 3 = 6 + 3 = 9

T₃ = T₂ + 3 = 9 + 3 = 12

T₄ = T₃ + 3 = 12 + 3 = 15

It took 3.5 hours for an airplane traveling at a constant speed of 550 miles per hour to reach its destination. What distance di

Nata [24]

The formula that we want to use here is S = D/T.

S = Speed
D = Distance
T = Time

So, we know that S = 550 and T = 3.5, so we can plug them in.

We get 550 = D/3.5
Multiply by 3.5 on each side, and you figure out that the plane has traveled 1925 miles.

Solve the following equation. Determine if the equation is an "identity" or "contradiction."

Leona [35]

To solve, we must get x by itself. the first step we must take is to remove all of the parentheses. To do this, we must use distribution to multiply 5 by x - 6.

5(x - 6) = 3x - 18 + 2x

5x - 30 = 3x - 18 + 2x

Next, we must add like terms.

5x - 30 = 5x - 18

Finally, we must get x by itself. to do this, we must subtract 5x from both sides.

5x - 30 - 5x = 5x - 18 - 5x

Then, we add like terms again.

-30 = -18

Because this is a false statement, the equation is a contradiction.

A track star in Arizona ran the 100 meter dash event is six track meets. Her average time for all six meets was 11.8 seconds. Sh

natima [27]

Answer:

A track star in Arizona running time in the last meet was 11.5 seconds.

Step-by-step explanation:

Given:

average time for all six meets = 11.8 seconds.

Time for 1st meet = 11.7 seconds.

Time for 2nd meet = 11.6 seconds.

Time for 3rd meet = 12 seconds.

Time for 4th meet = 12.1 seconds.

Time for 5th meet = 11.9 seconds.

We need to find the running time for her last meet.

Solution:

Let the running time for her last meet be 'x'.

So we can say that;

average time for all six meets is equal to sum of Time for 1st meet, Time for 2nd meet, Time for 3rd meet,Time for 4th meet, Time for 5th meet and time for her last meet and then divided by 6.

framing in equation form we get;

$\frac{11.7+11.6+12+12.1+11.9+x}{6}=11.8\\\\\frac{59.3+x}6 =11.8$

Now Multiplying both side by 6 we get;

$\frac{59.3+x}{6}\times 6= 11.8\times6\\\\59.3+x=70.8$

Now Subtracting both side by 59.3 we get;

$59.3+x-59.3=70.8-59.3\\\\x=11.5 \ s$

Hence A track star in Arizona running time in the last meet was 11.5 seconds.
