Step-by-step explanation:

the total amount of degrees  in a hexagon is 720. Divide that by 6 and you get 120. Each corner is 120. It doesnt have a right angle measure on it so it has to be lowerer then 90.

The fraction of the pitcher each type of juice are 1/3 and 2/3

From the question, we have the following parameters that can be used in our computation:

Parts = 6

Orange juice = 1

Peach juice = 2

using the above as a guide, we have the following:

Orange juice  : Peach juice = 1 : 2

Multiply by 2

So, we have

Orange juice  : Peach juice = 2 : 4

When represented as a fraction, we have

Orange juice = 1/3

Peach juice = 2/3

Hence, the fractions are 1/3 and 2/3

Answer:

x = 3

y = 6

Step-by-step explanation:

-4x- y = -18

2x + 3y = 24 (Multiply everything by 2)

-4x - y = -18

4x + 6y = 48

5y = 30

y = 6

-4x- y = -18

-4x - 6 = -18

-4x = -12

x = 3

The requirements for a given year to be a leap year are the year must be divisible by 4, if the year is divisible by 100, it is not a leap year, unless it is also divisible by 400.

In the Gregorian calendar, a leap year is a year that has 366 days instead of the usual 365 days. The reason for this is to account for the fact that the Earth takes slightly longer than 365 days to orbit the Sun.

This system of leap years helps to keep our calendar in synchronize with the astronomical year and ensure that seasonal events, such as the solstices and equinoxes, occur at approximately the same time each year.

For example, 1900 was not a leap year because it is divisible by 100 but not by 400, while 2000 was a leap year because it is divisible by both 100 and 400.

The probability that suits of cards are spades, hearts, and spades is 39/850 or 0.046.

According to the give question.

Three cards are drawn from a standard deck of cards without replacement.

Since,

The total number of cards in a standard deck = 52

Total number of spade cards = 13

Total number of heart cards = 13

Now,

The probabbility of getting first card as a spade card = 13/52 = 1/4

The probability of getting second card as heart card

= 13/(52 -1)     (cards are drawn without replacement)

= 13/51

The probability of getting third card as a spade card

= (13 - 1)/52 -2

= 12/50

= 6/25

Therefore, the probability that suits of the cards are spades, hearts, spades

= 1/4 × 13/51 × 6/25

= 39/850

= 0.046

Hence, the probability that suits of cards are spades, hearts, and spades is 39/850 or 0.046.

Answer:

DC⊥EF as the 2 angles in smallest triangle are 30 and 60 degrees, so the last one is 90 making Line DC perpendicular to Line EF.

Step-by-step explanation:

DC⊥EF means that Line DC is perpendicular (90 degrees) to EF.

To prove this, we can use the two angles of the small triangle created by the intersection of the triangles AEF and DCB.

The remaining angle of triangle AEF is 60, as all angles of triangles add up to 180 (so 180 - 12 = 60). This angle at F is shared with the little triangle.

Now we will get the angle at D using the triangle DCB. Since we are given two angles 90 and 60, angle D has to be 30.

So of our little triangle, we have angles 30 and 60, meaning the last one is 90 degrees and hence, DC⊥EF

The cost of a plumber's one-hour visit is $51, determined by the linear equation C = 51d, where C is the cost and d is the duration of the visit in hours.

If a plumber's visit lasts for a certain duration, the cost can be determined using the equation

                           C = 51d

where C is the cost and d is the duration of the visit in hours.

In this case, the duration of the plumber's visit is given as 1 hour. Substituting d = 1 in the equation, we get

                             C = 51(1) = $51

as the cost of the plumber's visit.

Therefore, if the plumber's visit lasts for one hour, it would cost $51 according to the given equation.

This cost may vary if the duration of the visit changes, as it is directly proportional to the duration of the visit.

Explanation:

The parent function y = |x| has its vertex at the origin (0,0). This is the lowest point on the V shaped graph.

The -2 at the end will shift every point 2 units down. This is because we're subtracting 2 from the y coordinate of each point.

So the vertex (0,0) moves down to (0, -2)

The given sequence converges to zero

The given sequence is {an}n = 1∞ = 1/ (n + 3).

The task is to find whether the sequence converges or diverges.

If it converges, then we have to determine the limit of the given sequence.

The general term of the sequence is given by,

an = 1/ (n + 3) ...[1]

The given sequence is

{an}n = 1∞ = 1/ (n + 3).

For the given sequence, let us check whether it is converging or diverging.

To determine if the sequence converges or diverges, we take the limit of the sequence.

Let, L = limit of sequence.

Then,

lim n→∞an = lim n→∞1/ (n + 3)

Put n = ∞ in [1].

an = 1/ (n + 3)an = 1/ (∞ + 3) = 0L = 0.

Hence,

lim n→∞an = 0.

Since limit exists, we can say that the sequence is convergent.

If the sequence is convergent, then we can find its limit.

To find the limit of the sequence, we can directly write the value of the limit.

L = 0.

Hence, the given sequence converges to zero.

We must calculate the standard deviation of the differences between the values in the matched pairs in order to build a confidence interval using those values.

The 95% confidence interval is another frequently used measure of accuracy. In order to calculate it, a range of values that is 95% likely to contain the true population mean must be created using the standard deviation.

According to the 68-95-99.7 Rule, 95% of values are within two standard deviations of the mean, so to calculate the 95% confidence interval, one need only add and deduct two standard deviations from the mean.

Data dispersion in relation to the mean is quantified by a standard deviation, or σ. Data are said to be more closely clustered around the mean when the standard deviation is low and more dispersed when the standard deviation is high.

The difference between the values in the matched pairs' standard deviation is calculated.

Answer:

To make it trinomial it has to be ax²+bx+c

Answer:

\((-3,4/375)\)

Step-by-step explanation:

Given

\(f(x) = \frac{1}{6}(\frac{2}{5})^x\)

Reflection: Across y-axis

Required

The ordered pair on g(x)

The rule of reflection across y-axis is:

\((x,y) = (-x,y)\)

So, we have:

\(g(x) = f(-x)\)

f(-x) is:

\(f(-x) = \frac{1}{6}(\frac{2}{5})^{-x\)

Recall that:

\(g(x) = f(-x)\)

Hence:

\(g(x) = \frac{1}{6}(\frac{2}{5})^{-x\)

From the options (missing in the question), the ordered pair is:

\((-3,4/375)\)

To check this, we have:

\(g(x) = \frac{1}{6}(\frac{2}{5})^{-x\)

\(g(-3) = \frac{1}{6}(\frac{2}{5})^{--3\)

\(g(-3) = \frac{1}{6}(\frac{2}{5})^{3\)

Expand

\(g(-3) = \frac{1}{6}(\frac{8}{125})\)

Simplify

\(g(-3) = \frac{1}{3}(\frac{4}{125})\)

Open bracket

\(g(-3) = \frac{4}{375}\)

Answer:

Step-by-step explanation:

The number of 3-point shots made is two more than half of the number of 2-point shots made.

Assume the number of 2-point shots is x.

Number of 3-point = 0.5x + 2

The relevant expression will be:

x + (0.5x + 2) = 20

1.5x + 2 = 20

1.5x = 20 - 2

x = 18/1.5

x = 12 shots

3 point shots = 20 - 12 = 8

There were 12 2-point shots and 8 3-point shots.

Total points :

= (12 * 2) + (8 * 3)

= 48 points

In linear functions, there is a constant difference between the y-values on a table. This means that it increases or decreases by the same amount per every equal interval.

For instance: 2, 4, 6, 8 ⇒ Constant difference of 2 every 1 term

To find the constant difference for this set of values, determine the constant difference (y), and by what interval this difference occurs (x).

Looking at the first two rows of the table, we now know that for every increase in 3 in the x-values yields an increase of 15 in the y-values.

We can write it like a fraction, with difference in y on top and difference in x at the bottom:

\(\dfrac{15}{3}\) ⇒ \(5\)

Congratulations! We have now found the slope of the line.

Linear equations are typically organized in slope-intercept form:

\(y=mx+b\)

Plug in our slope, and solve for the y-intercept by using one of the given points from the table:

\(y=5x+b\\-10=5(-1)+b\\-10=-5+b\\b=-5\)

Plug this back into the equation:

\(y=5x-5\)

To find n, plug in 20 as y and solve:

\(20=5n-5\\25=5n\\n=5\)

n = 5

Answer:

\( \frac{17}{k} \)

The values of x and y​ are x = 5 and y = 5.

The subtraction of vectors a and b can be represented as the vector sum of a and the negative of b:

a - b = a + (-b)

To find the negative of b, simply multiply each component by -1:

-b = (-1) × (1, 2) = (-1, -2)

So,

a - b = a + (-b) = (6, 7) + (-1, -2) = (5, 5)

Therefore, the values of x and y are 5 and 5 respectively.
