A table is shaped like a regular hexagon. The length of one side is (7x + 4) in. and the length of another side is (8x − 1) in. Find the length of a side.

The length of a side of the table is

Answers

Answer:

39 in.

Step-by-step explanation:

As  it's a regular hexagon all sides are congruent.

Therefore

7x + 4 = 8x - 1

4 + 1 = 8x - 7x

x = 5.

So the required length is 7(5) + 4 = 39 in.

The cost to mail a package varies directly to the weight of the package. If a 14- ounce package costs $4.48 to mail, find the weight of a package that cost $8 to mail. ​

Answers

Answer:

Step-by-step explanation:

Ok so first, we must figure out what 1 once costs. This can be done by divideing 4.48(cost) by 14(weight).

You should get 0.32.

Now just multiply by 8 and you should get your answer. This answer is 2.56.

Answer:

2.56

Another way this can be done is dividing 8(second weight) by 14(first weight) which will get you the difference. This is 0.5714 blah blah blah goes on for a long time. Now, take this number and multiply it by the 4.48(first cost). This should get you 2.56.

Answers

Answer:

1 / 16

Step-by-step explanation:

Number of options = 4

Number of correct answers = 1

Number points gained for a correct answer = 1

Number of points lost for an incorrect answer = 1/4 = 0.25

Probability of choosing a correct option = 1/4

Probability of choosing an incorrect option = 3/4

x ____ 1 ______ - 1/4

P(x) __ 1/4 ______ 3/4

Expected gain or loss :

E(x) = Σx*p(x)

E(x) = (1 * 1/4) + (-1/4 * 3/4)

E(x) = 1/4 - 3/16

E(x) = (4 - 3) / 16

E(x) = 1 /16

Dr. Baker, a veterinarian, recorded the weight of each newborn kitten her office saw today.
Kittens' weights (g)

Answers

Answer:

30 grams is the answer

As per the given data, the interquartile range of the kittens' weights is 60 g.

What is interquartile range?

The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles.

The IQR is the range between the first quartile (Q1) and the third quartile (Q3). It represents the range of the middle 50% of the data set.

To find the interquartile range (IQR) of the kittens' weights, we need to first find the median and the quartiles.

Find the median (Q2):

The median is the middle value when the data is arranged in order. In this case, we have an even number of data points, so we take the average of the two middle values:

100, 120, 140, 160, 180, 200

The middle values are 140 and 160, so the median is:

(Q2) = (140 + 160) / 2 = 150

Find the first quartile (Q1):

The first quartile is the middle value of the lower half of the data. To find Q1, we take the median of the lower half:

100, 120, 140

The median is 120, so Q1 is:

Q1 = 120

Find the third quartile (Q3):

The third quartile is the middle value of the upper half of the data. To find Q3, we take the median of the upper half:

160, 180, 200

The median is 180, so Q3 is:

Q3 = 180

Calculate the interquartile range:

The interquartile range is the difference between the third and first quartiles:

IQR = Q3 - Q1 = 180 - 120 = 60

Therefore, the interquartile range of the kittens' weights is 60 g.

Step-by-step explanation:

Plug in the coordinate point and check:

Since 69 is indeed greater than 4, then (6,1) is a solution to the inequality.

Write the square roots of 49 i in ascending order of the angle.

Answers

Answer:

The square roots of 49·i in ascending order are;

1) -7·(cos(45°) + i·sin(45°))

2) 7·(cos(45°) + i·sin(45°))

Step-by-step explanation:

The square root of complex numbers 49·i is found as follows;

x + y·i = r·(cosθ + i·sinθ)

Where;

r = √(x² + y²)

θ = arctan(y/x)

Therefore;

49·i = 0 + 49·i

Therefore, we have;

r = √(0² + 49²) = 49

θ = arctan(49/0) → 90°

Therefore, we have;

49·i = 49·(cos(90°) + i·sin(90°)

By De Moivre's formula, we have;

[tex]r \cdot (cos(\theta) + i \cdot sin(\theta) )^{\dfrac{1}{2}} = \pm \sqrt{r} \cdot \left (cos\left (\dfrac{\theta}{2} \right ) + i \cdot sin\left (\dfrac{\theta}{2} \right ) \right )[/tex]

Therefore;

√(49·i) = √(49·(cos(90°) + i·sin(90°)) = ± √49·(cos(90°/2) + i·sin(90°/2))

∴ √(49·i) = ± √49·(cos(90°/2) + i·sin(90°/2)) = ± 7·(cos(45°) + i·sin(45°))

√(49·i) = ± 7·(cos(45°) + i·sin(45°))

The square roots of 49·i in ascending order are;

√(49·i) = - 7·(cos(45°) + i·sin(45°))  and  7·(cos(45°) + i·sin(45°))
