Total 860 1550 2320 4730

What percent of the total is made up of Green Planes?

Yellow makes up approximately 17.32% of the total number of trips.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred.

To find the percentage of the total that Yellow makes up, divide the total number of Yellow trips by the overall total number of trips, and then multiply by 100 to convert to a percentage -

Yellow total = 820

Overall total = 4730

Yellow percentage = (820/4730) x 100%

Yellow percentage = 0.1734

Yellow percentage = 17.34%

Therefore, Yellow makes up approximately 17.32% of the total number of trips.

h(-2) = 3

h(0) = 0

h(5) = 3/4

This can be solved by using the concept of function.

In arithmetic, a function from one set to another, X to Y, allocates precisely one element of Y to each element of X. Both of the set X and the set Y usually known as the function's domain and codomain, respectively. The basic conception of functions was the relationship between fluctuating quantities and other variables.

A function with the name f is defined by the formula y=f(x). This is understood to mean "y is a function of x." The input value, also known as an independent variable, is represented by the letter X. The outcome value, or dependent variable, is denoted by the letter y, or f(x).

This is a piece wise-defined function:

For h(-2):

h(-2) = 3

For h (0):

h(0) = (x + 1)²- 1

h(0) = (0 + 1)² - 1

h(0) = 1 - 1

The reflection of the vector v = [8, 5, 7] in the line L is [2/3, -67/3, 31/3].

Vector, in mathematics, a quantity that has both magnitude and direction. It is often represented by an arrow whose length is proportional to the magnitude of the quantity and whose direction is the same as that of the quantity.

The reflection of a vector v in a line L can be found by projecting v onto L and then doubling the projection.

To project v onto L, we need to find the projection of v onto a vector that lies on L. Let's call this vector a. We can find a by normalizing the vector [1, -2, 2] to get:

a = [1/3, -2/3, 2/3]

Now, the projection of v onto a is given by the dot product of v and a:

proj_v_a = (v . a) * a = [(81/3) + (5(-2/3)) + (7*2/3)] * [1/3, -2/3, 2/3]

= [13/3, -26/3, 26/3]

To find the reflection of v in L, we need to double the projection and subtract it from v:

ref_v_L = 2 * proj_v_a - v

= 2 * [13/3, -26/3, 26/3] - [8, 5, 7]

= [26/3, -52/3, 52/3] - [8, 5, 7]

= [2/3, -67/3, 31/3]

Therefore, the reflection of the vector v = [8, 5, 7] in the line L is [2/3, -67/3, 31/3].

The program to find the divisible values gives the number of multiples of 2 between 3 and 8 inclusive is 3

To check if an integer is divisible by x, you could divide it by x and check if the remainder is 0.

If the remainder is 0, then the integer is divisible by x and therefore is a multiple of x.

We can use this concept to find the number of multiples of x between low and high inclusive.

If low is 3, high is 8, and x is 2, then we can check if each number between 3 and 8 is divisible by 2.

3 is not divisible by 2, so it is not a multiple of 2.

4, however, is divisible by 2, so it is a multiple of 2.

5 is not divisible by 2, so it is not a multiple of 2.

6, however, is divisible by 2, so it is a multiple of 2.

Then 7 is not divisible by 2, so it is not a multiple of 2. 8 is divisible by 2, so it is a multiple of 2.

Now that we know k is 3/2, we can use the formula to find the value of y when x is 14:

y = (3/2)(14) = 21

Therefore, when x = 14, y = 21.

A variable is a number in mathematics that can change depending on the issue. Several statements and equations in mathematics use the generic letters x, y, and z. Or to put it another way, a variable is a symbol that denotes an unknowable numerical value. Assume that x + 5 = 10. The term "x" is used here.

Since y varies directly with x, we know that the ratio of y to x is constant. Let's call this constant k. Then we can write:

y = kx

To find k, we can use the first two rows of the table:

When x = 2, y = 3, so:

3 = k(2)

k = 3/2

When x = 10, y = 15, so:

15 = k(10)

k = 3/2 (which matches the previous calculation)

Now we can use k to find y when x = 14:

y = (3/2)(14) = 21

Let's call the smaller number "x". Since the larger number exceeds the smaller number by 1, we can call the larger number "x + 1".

The problem tells us that the sum of the numbers is 25, so we can set up an equation:

x + (x + 1) = 25

Simplifying and solving for x:

2x + 1 = 25

2x = 24

x = 12

So the smaller number is 12. To find the larger number, we can use x + 1:

x + 1 = 12 + 1 = 13

So the larger number is 13.

Therefore, the two numbers are 12 and 13.

The requried Kristen travels 9.5 miles to work. Option D is correct.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,
We can use the formula distance = rate x time to solve this problem.

When Kristen is biking, her rate is 10 mph and her time is 1/4 hour. So her distance traveled is:

distance = rate x time

distance = 10 mph x 1/4 hour

distance = 2.5 miles

When Kristen is on the train, her rate is 28 mph and her time is another 1/4 hour. So her distance traveled on the train is:

distance = rate x time

distance = 28 mph x 1/4 hour

distance = 7 miles

Therefore, the total distance Kristen travels to work is the sum of the distances she traveled while biking and on the train:

total distance = distance biked + distance on train

total distance = 2.5 miles + 7 miles

total distance = 9.5 miles

So Kristen travels 9.5 miles to work.

Answer:

Rs 1098 can buy 45.75 apples (or approximately 45 apples, since we cannot buy a fractional part of an apple).

Step-by-step explanation:

We can use proportionality to solve this problem. Since the price of apples is directly proportional to the number of apples, we can set up a proportion:

2 apples / Rs 48 = x apples / Rs 1098

To solve for x, we can cross-multiply and simplify:

2 * Rs 1098 = 48 * x

Rs 2196 = 48x

x = Rs 2196 / 48

x = 45.75

Therefore, Rs 1098 can buy 45.75 apples (or approximately 45 apples, since we cannot buy a fractional part of an apple).

If a, b, c, and d are four different numbers and the proportion a/b = c/d is true, then none of the statements is false.

What is proportion?

In general, the term "proportion" refers to a part, share, or amount that is compared to a whole. According to the definition of proportion, two ratios are in proportion when they are equal.

Since a/b = c/d, are proportional then can cross-multiply to get ad = bc.

Now, evaluate each statement -

A. b/a = d/c

Cross-multiplying, it is obtained that bc = ad, which is true based on the original proportion.

Therefore, this statement is true.

B. a/c = b/d

Cross-multiplying, it is obtained ad = bc, which is also true based on the original proportion.

Therefore, this statement is true.

C. b/a = c/d

This is equivalent to the original proportion, so it is true.

D. (a + b)/b = (c + d)/d

Simplify the equation -

d(a + b) = b(c + d)

da + db = bc + bd

da = bc

Cross-multiplying, it is obtained that da = bc, which is true based on the original proportion.

Therefore, this statement is true.

The 90% confidence interval for the mean number of books people read is (-16, 38.6).

To construct a 90% confidence interval for the mean number of books people read, we first need to find the critical value (z*) that corresponds to a 90% confidence level. This can be found using a z-table or calculator. The critical value for a 90% confidence level is 1.645.

Next, we need to calculate the margin of error (ME) using the formula ME = z* x SE, where SE is the standard error. In this case, SE = 16.6 books, so ME = 1.645 x 16.6 = 27.3 books.

Finally, we can construct the 90% confidence interval by adding and subtracting the margin of error from the sample mean (x overbar). The confidence interval is:

(x overbar - ME, x overbar + ME) = (11.3 - 27.3, 11.3 + 27.3) = (-16, 38.6)

We will then factor the denominator. As the denominator is a difference of perfect squares (in the form [tex]x^{2} -a^{2}[/tex]), we know that it can be factored in the form (x + a)(x - a), a being the square root of the number given. (In this case, a = 7, because the square root of 49 is 7.)
