the ratio of empty seats to full seats in an auditorium is 3:7. if there are 203 full seats, find the total number of seats.

Answer:

12

Step-by-step explanation:

since 1 inch equals 2.54 cm then 11 inches equals 27.94 cm

27.94 ÷ 2.33 = 11.99

Answer:  45

=====================================================

Work Shown:

n = number of rolls = 150

p = probability of rolling a "1" = 0.3

n*p = expected number of "1"s that show up out of the 150 rolls

n*p = 150*0.3

n*p = 45

We expect about 45 ones will show up.

Answer:

4.8

Step-by-step explanation:

We are given the hypotunese or the slanted side which is the ladder length which is 14.

We are given an angle at the bottom which is 70 degrees.

We are asked to find the horizontal side which is adjacent to the angle at the bottom.

Since we have a hypotunese and a side adjacent to the angle, we are going to use the function cosine.

we use this formula

[tex] \cos(theta) = \frac{adj}{hypo} [/tex]

[tex] \cos(70) = \frac{x}{14} [/tex]

x=4.8

Answer:

Andrew is wrong

Step-by-step explanation:

You need to add the fractions together. To add fractions you need a common denominator, so for mike 2/4 changes to 6/12 and 1/3 changes to 4/12 meaning he read 10/12 of the book. Andy read 1/2 or 5/10 and 1/5 or 2/10 so 7/10. By cross multiplying we see that 10/12 is greater so mike read more.

Answer:

Mike read more of the book

Step-by-step explanation:

I made 1/3 and 1/5 into a equal fraction and 1/3 would be 5/15 and 1/5 would be 3/15 and 2/4 and 1/2 are the same so it just comes to to 1/3 and 1/5. Mike read more of the book than Andy

Answer:

60 degrees each

Step-by-step explanation:

For the triangle, the sum of the interior angles is equal to the exterior

Let x and y be interior

Let z be the third angle

w be the exterior

w = x+y

120 = x+y

If the exterior angle is twice of each of the interior remote angles, then;

2x = 2y

x = y

120 = x+x

2x = 120

x = 60

Since x = y, y  = 60 degres

From the triangle, the third angle will be 180 - 120

z = 180-120

z = 60

The measures of the 3 angles are 60 degrees each

Answer:

(280+7) ÷ (7+7)

Step-by-step explanation:

hopefully this helps ya

The equation that is equal to 287 ÷ 7 is (280 + 7) ÷ (7 + 7). The correct option is C.

An equation is a statement in mathematics that shows that two expressions are equal. It has two sides that are separated by an equal sign.

To find the value of 287 ÷ 7, we can use the following methods:

We can simplify 287 ÷ 7 as follows:

287 ÷ 7 = 280 ÷ 7 + 7 ÷ 7

Note that 7 ÷ 7 simplifies to 1, so we have:

287 ÷ 7 = 280 ÷ 7 + 1

Therefore, the answer is C. (280 + 7) ÷ (7 + 7) = 287 ÷ 14 = 20.5.

Answer:

3 comparisons

Step-by-step explanation:

Given:

[tex]List: 1 , 5 ,10 , 13 , 48 , 68 , 100 , 101[/tex]

Required

Determine the number of comparisons to get to 101

The length of the list is 8. So, the first index is 0 and the last is 7.

We have:

[tex]List[0] = 1[/tex]   [tex]List[1] = 5[/tex]   [tex]List[2] = 10[/tex]     [tex]List[3] = 13[/tex]    

[tex]List[4] = 48[/tex]    [tex]List[5] = 68[/tex]    [tex]List[6] = 100[/tex]    [tex]List[7] = 101[/tex]

Initially:

[tex]begin = 0[/tex] -- first index

[tex]end = 7[/tex] --- last index

Start by calculating the mid-item

[tex]mid = \frac{1}{2}(begin + end)[/tex]

[tex]mid = \frac{1}{2}(0 + 7)[/tex]

[tex]mid = \frac{1}{2}(7)[/tex]

[tex]mid = 3.5[/tex]

[tex]mid = 4[/tex] --- approximated.

The mid-index is 4 and the item is:

[tex]List[4] = 48[/tex]

101 is on the right of 48.

So, we calculate the new begin index.

[tex]begin = mid + 1[/tex]

[tex]begin= 4 +1[/tex]

[tex]begin = 5[/tex]

Calculate mid

[tex]mid = \frac{1}{2}(begin + end)[/tex]

[tex]mid = \frac{1}{2}(5 + 7)[/tex]

[tex]mid = \frac{1}{2}(12)[/tex]

[tex]mid= 6[/tex]

The mid-index is 6 and the item is:

[tex]List[6] = 100[/tex]

101 is on the right of 100.

So, we calculate the new begin index.

[tex]begin = mid + 1[/tex]

[tex]begin = 6 +1[/tex]

[tex]begin= 7[/tex]

Calculate mid

[tex]mid = \frac{1}{2}(begin + end)[/tex]

[tex]mid = \frac{1}{2}(7+7)[/tex]

[tex]mid = \frac{1}{2}(14)[/tex]

[tex]mid = 7[/tex]

At this point, the mid-index is at 101

i.e.

[tex]List[7] = 101[/tex]

This implies that, we have located 101.

So far, we made 3 comparisons

[tex]4[/tex] comparisons are needed to find the number [tex]101[/tex] in the list.

Binary search algorithm searches for a number in a sorted list/array. It does this by first comparing the number in the middle of the array with the number searched for, then recursively continuing the search on either the left-half or right-half of the array if the middle comparison failed.

The element [tex]101[/tex], is at the rightmost end of the array. This means that the algorithm will have a worst case running time. The worst case running time of a binary search algorithm is given by

[tex]T_n=\lfloor log_2(n)+1\rfloor[/tex]

where [tex]\lfloor x \rfloor[/tex] is the floor function that gives the greatest integer less than or equal to [tex]x[/tex], and [tex]log_2(n)[/tex] is the logarithm of [tex]n[/tex] to base [tex]2[/tex]

In our case, the number of elements in the array, [tex]n=8[/tex]. So,

[tex]T_n=\lfloor log_2(n)+1\rfloor\\\implies T_8=\lfloor log_2(8)+1\rfloor = 4\\[/tex]

So, the algorithm will need to make [tex]4[/tex] mid-array comparisons to get to [tex]101[/tex].
