There are N coins, each showing either heads or tails. We would like the number of coins showing heads to be equal to the number showing tails. What is the minimum number of coins that mmust be turned over?
Write a function:
int solution (vector &A);
that, given an array A consisting of N integers representing the coins,
returns the minimum number of coins that must be flipped.
Consecutive elements of array A represent consecutive coins, and contain either a 0 (heads) or a 1 (tails).
Examples:
1. Given array A = [1, 0, 0, 1, 0, 0], there are four coins showing heads and two showing tails. The function should return 1, as after reversing one of the coins showing heads, there will be three coins showing heads and three showing tails.

The highest z-score is corresponding to Calculus, hence in Calculus Kary have the highest relative score using standard deviation and mean concept i.e. 2.5.

As per the question statement, It is given that Kary took 4 courses last semester i.e., History, Biology, Calculus, and Physics. The means and standard deviations for the final exams, and Kary's scores are given as follows:

History 53   16

Blology 77    10

Calculus 70   12

Physlcs 60  14

Kary's score In the above four subjects are: 69,74.5,88,67

We are supposed to convert Kary's score in z-score which is as follows:

History : [tex]\frac{69-53}{16} =1[/tex]

Biology: [tex]\frac{74.5-77}{10}=-0.25[/tex]

Calculus: [tex]\frac{88-70}{12} =1.5[/tex]

Physics: [tex]\frac{67-60}{14} = 0.5[/tex]

From the above calculations, it is clear that The highest z-score is corresponding to Calculus, hence in Calculus Kary have the highest relative score using standard deviation and mean concept i.e., [tex]1.5[/tex]

Answer:

88,86416

Step-by-step explanation:

The pairs of equivalent expressions are:

(-14 + 3/2b) - (1 + 8/2b) --> -15 - 5/2b

(5 + 2b) + (2b + 3/2) --> 4b + 13/2

(7/2b - 3) - (8 + 6b) --> -5/2b - 11

(-10 + b) + (7b - 5) --> 8b - 15

Evaluate each of the given expressions in order to find out which expression is equivalent to each.

(-14 + 3/2b) - (1 + 8/2b) = (-14 + 3/2b) - (1 + 4b)

= -14 + 3/2b - 1 - 4b

= -15 - 5/2b

(5 + 2b) + (2b + 3/2) = 5 + 2b + 2b + 3/2

13/2 + 4b

4b + 13/2

(7/2b - 3) - (8 + 6b) = 7/2b - 3 - 8 - 6b

-5/2b - 11

(-10 + b) + (7b - 5) = -10 + b + 7b - 5

= -15 + 8b

= 8b - 15

Thus, the pairs of equivalent expressions are:

(-14 + 3/2b) - (1 + 8/2b) --> -15 - 5/2b

(5 + 2b) + (2b + 3/2) --> 4b + 13/2

(7/2b - 3) - (8 + 6b) --> -5/2b - 11

(-10 + b) + (7b - 5) --> 8b - 15

Here, we are given that Jonah made a scale drawing of the picnic area in which the 70 yards wide picnic area in real life, was 10 inches wide in the drawing.

As per mathematical measurements-

1 yard = 3 feet

and 1 feet = 12 inches

Thus, 3 feet = 12 x 3 inches

= 36 inches

Therefore, we get that 1 yard = 36 inches

Now, the picnic area is 70 yards

the picnic area in inches is = 70 x 36 inches wide

Carl calculates the z-score corresponding to the weight 255oz= -1.5.

Now, Carl decides to find the percent associated with boxes less then 255 oz, so he rounds to hundred and substract 50% - 7% = 43%.

Given that,

In an orchard, apple weights are typically distributed. Fred the farmer concludes from a sample that the average weight of a box of apples is 270 ounces, with a standard deviation of 10 ounces.

He is interested in knowing what proportion of the apple boxes he has gathered for sale will weigh less than 255 oz.

Mean is 270

Standard deviation is 10

x = 255

Formula for z-score,

z = (x - mean)/SD

z = (255 - 270) / 10

=> z = -15 / 10

=> z = -1.5

Hence, by using z-table,

-1.5 equates to 0.0668, which suggests that 0.07

Therefore, 7% of Apple boxes weigh less than 255 oz.

The ratio of boxes is between 255 oz and 270 oz,

Calculating the proportion

Now,

50% - 7% = 43%.

Therefore, Carl calculates the z-score corresponding to the weight 255oz= -1.5.

The cost to send a letter that weighs 5 ounces is $11.75.

Flat rate = $8.00

Charges on every ounce = $0.75

Given equation :

y = 0.75x + 8.00

'y' = Cost of the postage

'x' = Weight of the letter in ounces

According to the question we can determine the cost of mailing a letter with the help of given equation (y = 0.75x + 8.00).

We have given that the weight of letter that need to send is 5 ounces.

So, x = 5

Lets find the cost of postage,

y = 0.75x + 8.00

y = (0.75 × 5) + 8.00

y = 3.75 + 8.00

y = $11.75

The equation that represents the depth of snow on Emily's lawn t hours after the snow stopped falling is

S = 15 - 0.75t

From the question, we are to write an equation for S, in terms of t, that represents the depth of the snow on Emily's lawn, t hours after the snow stopped falling

From the given information,

"There was a depth of 15 inches of snow on the lawn when the storm ended"

and

"after 4 hours, the depth of snow was down to 12 inches"

That is,

The snow has reduced by 15 - 12 inches after 4 hours

15 - 12 = 3

Thus,

The snow has reduced by 3 inches after 4 hours

Now,

If the snow reduced by 3 inches after 4 hours,

Then,

The snow will reduce by x inches after 1 hour

x = (3×1)/4

x = 3/4 inches

x = 0.75 inches

This means the snow reduces by 0.75 inches every hour.

Now,

After t hours, the snow would have reduced by 0.75t

Thus, the depth of the snow, S, after t hours will be

S = 15 - 0.75t

Hence, the equation that represents the depth of snow on Emily's lawn t hours after the snow stopped falling is
