Answer:

5: 0 successes

6: 5 successes

7: 8 successes

8: 6 successes

9: 6 successes

10: 1 success

We need to use her results to estimate the probability that she succeeds at fewer than 7 free-throws in a sample of 10 free-throws.

First, find out how many successes were less than 7 (out of 25), which is 5.

now, we divide 5 by 25 (5/25, formula being number/total attempts) and simplify into a decimal, which comes out to 0.2

Step-by-step explanation:

Disclaimer: The question was incomplete. The complete question can be seen in the image attached.

The estimated probability of Maria succeeding at fewer than 7 free throws in a sample of 10 free throws is 1/5 or 0.2.

The probability of an event is the fractional value showing how likely is that event to occur. It is determined by the formula =

The number of outcomes favorable to the event/the total number of outcomes.

The results from the 25 samples showing the number of success in each trial of 10 throws are:

5 success: 0 outcomes

6 success: 5 outcomes

7 success: 8 outcomes

8 success: 6 outcomes

9 success: 5 outcomes

10 success: 1 outcome.

We are asked to estimate the probability that Maria succeeds at fewer than 7 throws in a sample of 10 free throws.

From the result of 25 samples of 10 free throws each, we see that Maria succeeds fewer than 7 times, that is, 5 and 6 times for 0 + 5 = 5 outcomes.

∴ The probability of Maria succeeding at fewer than 7 throws in a sample of 10 free throws = 5/25 (favorable outcomes/total outcomes)

= 1/5 or 0.2.

So, the estimated probability of Maria succeeding at fewer than 7 free throws in a sample of 10 free throws is 1/5 or 0.2.

Answer:

D. 60cm²

Step-by-step explanation:

First, notice how the partially shaded squares fit perfectly into one another (the squares are perfectly cut from corner to corner). Once you match these squares to one another, you can then figure out that they add up to three full squares.

Secondly, measure how many squares there will be in the diagram after adding up the partial squares (resulting in a total of 15).

Finally, calculate the area of one of the squares (2cm x 2cm), which results in 4cm². As you have 15 total squares, multiply 4cm² by that to get the final answer of 60cm².

There are 4 positions in the string that each have 25 choices (any letter in the English alphabet except A) and the other positions are filled with A, so there are 25⁴ possible strings containing exactly 7 A's.

Overall, there are 26¹¹ possible strings of length 11.

The measure of one part of a rectangle divided into 4 parts is 1/4

If 1 whole is divided into 4 equal parts

= 1/4

So, if the perimeter of the rectangle is 60cm

1 part of 4 = 1/4 × 60cm

= 60/4

= 15 cm

Therefore, the measure of one part of a rectangle divided into 4 parts is 1/4

Answer:

L= P/2 - 6

Step-by-step explanation:

As you know that the Perimeter of a Rectangle = 2(L+W)

since Perimeter = P  and Width = 6

Then P = 2(L+6)

Expanding

P=2L+12  -->  2L=P-12

Then L=(P-12)/2=P/2-6

The perimeter is twice the sum of width and length. Then the length of the rectangle is P/2 – 6 units.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

If the width of a rectangle with perimeter P is 6 units.

Perimeter = P

Width = 6 units

Then the length of the rectangle will be

Perimeter = 2 (Width + Length)

             P = 2 (6 + L)

             L = P/2 – 6

The length of the rectangle is P/2 – 6 units.

Answer: D: 321. 39 in³

Step-by-step explanation:

Bowling balls are spheres:

the volume of a sphere is calculated as:

V ≅321.39 in³

By finding the linear equation that relates distance and time, we can see that the complete table is:

time (hours)   distance (miles)

2                              100

1.5                             75

t                              (50)*t

1                                50

6                               300

d/(50)                          d

After a small online search, I've found that the table is:

time (hours)   distance (miles)

2

1.5

t  

                                50

                               300

                                  d

Now, remember the relation:

distance = speed*time.

In this case, we know that the speed is 50 mi/h, so if we define d as the distance and t as the time, we can write:

d = (50mi/h)*t

To complete the table, we just replace the value that appears in the table, and then we solve the equation for the other variable.

First we have t = 2 hours:

d = (50 mi/h)*2h = 100 mi

Then we have t = 1.5 hours

d = (50 mi/h)*1.5 h = 75 mi

Then we assume that we evaluate in t, so there we just write the equation:

d = (50 mi/h)*t

Now we go to the other side of the table, now we evaluate d, so we can write:

t = d/(50 mi/h)

(that is what goes in the table when we need to evaluate in d).

Then the fourth place in the table has d = 50 mi, replacing that:

t = (50mi)/(50 mi/h) = 1h

And finally, we evaluate in d = 300mi

t = (300 mi)/(50 mi/h) = 6h

Then the complete table is just:

time (hours)   distance (miles)

2                              100

1.5                             75

t                              (50)*t

1                                50
