Answer:

\frac{1}{16}

Step-by-step explanation:

Given : The number of marbles of different colors stored in a hat is listed below:

8 red marbles

10 green marbles

6 blue marbles

To Find: What is the probability that Tessa takes out a blue marble in both draws?

Solution:

8 red marbles

10 green marbles

6 blue marbles

Total Marbles = 8+10+6= 24

Probability of getting blue marble on first draw = \frac{\text{No. of blue marbles}}{\text{Total no. of marbles}}

Probability of getting blue marble on first draw = \frac{6}{24}

Now the marble is replaced

Probability of getting blue marble on second draw = \frac{\text{No. of blue marbles}}{\text{Total no. of marbles}}

Probability of getting blue marble on second draw = \frac{6}{24}

So, probability of getting blue marble on both the draws =  \frac{6}{24} \times \frac{6}{24}

                                                                                               =  \frac{36}{576}

                                                                                               =  \frac{1}{16}

Hence the probability that Tessa takes out a blue marble in both draws is \frac{1}{16}

There is a 1/4 chance of getting the Blue Marble out of the bag. But when it is 2 in a row you have to multiply your chances so it would be 1/4 * 1/4 or 1/16

The minimum value of f(x) = x3 – 3x2 – 9x + 2 on the interval [–4, 0] is
garri49 [273]

Answer:

-74

Step-by-step explanation:

Graph the function. See attached picture. Between the interval where -4 > x < 0, the graph rises up to a peak and descends back down when x = 0. This means the minimum value will be where x = -4.

Substitute x = -4 into the equation.

f(-4) = (-4)^3 -3(-4)^2 - 9(-4) + 2

f(-4) = -64 -3(16) +36 + 2

f(-4) = -64 - 48 + 36 + 2

f(-4) = -74

Explain how to find the estimated sum of 5/8+2/9 . Make sure to include at least one type of model.
OverLord2011 [107]
In this expression you would have to use the PEMDAS method. First divide, so (5 divided by 8) + (2 divided by 9). 
The answer you would get is: (0.625) + (0.222)
The final answer is: 0.847

Please help solve with working much appreciated!
Lapatulllka [165]

The right answer is Option A.

Step-by-step explanation:

Given,

Heart rate goal = I

Heart rate reserve = H

70% of H = \frac{70}{100}H = 0.7H

Resting heart rate = R

According to given statement,

70% of heart rate reserved is added to resting heart rate to calculate heart rate goal, therefore,

I = R + 0.7H

I=R+0.7H represents the given situation.

The right answer is Option A.
