m<A = 112.5

m<B = 67.5

m<C = 67.5

m<D = 112.5

Consider the provided information.

The sum of all interior angle of a polygon is: (n-2)*180

Substitute n = 8.

(8-2)*180 = 1080

Thus, the measure of each angle is:

∠B and ∠C are congruent and their sum is 135°

∠B+∠C=135°

∠B=67.5°

Hence, the m angle B and m angle C is 67.5°.

The sum of all angles of a quadrilateral is 360°.

∠A+∠D+∠B+∠C=360°

∠A+∠D=360°-135°

∠A+∠D=225°

∠A and ∠D are congruent and their sum is 225°

∠A+∠D=225°

∠A=∠D=112.5°

Hence, the m angle A and m angle D is 112.5°.

The notation used for a vector pointing into the point is X.

A quantity with a magnitude and direction is called a vector. A vector quantity will be identified in these annotations by a bold letter (such as the electric field vector E). Vectors appear graphically as straight arrows. The magnitude of the vector is commonly represented by the length of the arrow, and both the arrow and the vector point in the same general direction.

Arrows are drawn on the page to represent vectors in the page's plane. Typically, circles with an X engraved on them are used to represent vectors that enter the screen's plane. A vector that deviates from the screen's plane is often represented by circles with dots in the center.

As given in the question,

Condition for the expression:

Sally and Anne both went for a movie.

Each one purchased a drink.

Shared one popcorn and one veggie bought by them.

Consider movie ticket price = 9

drink price = 1.35

Popcorn price = 3.50

Veggie price = 1.74

Explanation for different expressions are:

1. one-half (9 + 1. 35 + 3. 50 + 1. 74)

Here sum of all the amount is divided equally, which is not correct as movie ticket and drink they have purchased individually.

2.  9 + 1. 35 + one-half (3. 50 + 1. 74)

This is correct option as it represents :

Movie ticket price = 9

Drink = 1.35

one-half (3. 50 + 1. 74) = one popcorn and one veggie divided equally.

3. 18 + 2. 70 + one-half (3. 50 + 1. 74)

As per consideration of price this is not correct option.

Movie ticket price =18

Drink = 2.70

one-half (3. 50 + 1. 74) = one popcorn and one veggie divided equally.

4. 9+1. 35+2(3. 50+1. 7)

This is not correct option as popcorn and veggie price is doubled.

Since the circle is circumscribed about an equilateral triangle, its center is also the center of the triangle.
So the radius of the circle is $r = 9$ units. The area of the circle is $\pi r^2 = \pi \cdot 9^2 = \boxed{81\pi}$ square units.

To find the area of the circumscribed circle around an equilateral triangle, we can follow these steps:
1. Calculate the height of the equilateral triangle.
2. Find the circumradius (radius of the circumscribed circle).
3. Calculate the area of the circle.
Step 1: Calculate the height of the equilateral triangle:
In an equilateral triangle, the height bisects one of the sides, creating two 30-60-90 right triangles. Let's call the height h.
Using the Pythagorean theorem on the 30-60-90 right triangle, we have:
(9/2)^2 + h^2 = 9^2
(81/4) + h^2 = 81
h^2 = 81 - (81/4)
h^2 = (243/4)
h = √(243/4) = √243/2
Step 2: Find the circumradius (R):
In an equilateral triangle, the circumradius (R) is related to the height (h) and the side length (s) by the formula:
R = (s/2) * (1 / sin(60°))
Since sin(60°) = √3 / 2,
R = (9/2) * (2 / √3) = (9/√3) * (√3/√3) = 3√3
Step 3: Calculate the area of the circle:
The area of the circumscribed circle can be found using the formula:
Area = πR^2
Area = π(3√3)^2
Area = π(27)
So, the area of the circumscribed circle is 27π square units.

No, the Normal/large sample condition is not met for constructing at confidence interval. Option C.

To estimate the amount of carbon emissions released by cars, the mean weight of cars must be estimated. In this case, a random sample of 20 cars is selected and their mean weight is calculated. The conditions for constructing a confidence interval are met if the following conditions are satisfied:
1. Random Condition: The sample is randomly selected.
2. 10% Condition: The sample size is less than 10% of the population size.
3. Normal/Large Sample Condition: The sample size is large enough (usually n≥30) for the Central Limit Theorem to apply, or the population distribution is approximately normal.
In this scenario, the random condition is met since the cars are randomly selected. The 10% condition is also met, assuming there are more than 200 cars in the population. However, the Normal/large sample condition is not met since the sample size of 20 is less than the recommended threshold of 30.
Therefore, the answer is: No, the Normal/large sample condition is not met.

Answer:

x power 3(x cube)- 6x -72=0 there it has change to quadratic equation x power 3(x cube)-12x+6x-72=0

Answer:

4.6

Step-by-step explanation:

Y needs to = 72. When x=5, Y = X3 - 6X Y = 53 - 6(5) Y = 125 - 30 = 95 95 > 72 95 is way too high so we try a lower number

When x=4 Y= X3 -6X Y = 43 - 6(4) Y = 64 - 24 Y = 40 40 < 72 40 is way too low so we try a higher number, 4.5

When x=4.5 Y = X3 - 6(4.5) Y = 4.53 - 6(4.5) Y = 64.125 64.125 < 72 64.125 is too low so we try a slightly higher number: 4.6

When x=4.6 Y = X3 - 6(X) Y = 4.63 - 6(4.6) Y = 97.336 - 27.6 Y = 69.736 69.736 < 72 69.736 is too low so we try a slightly higher number

When x=4.7 Y = X3 - 6(X) Y = 4.73 - 6(4.7) Y = 103.823 - 28.2 Y = 75.623 75.623 > 72 75.623 is too high so we should try a number in between 4.6 and 4.7

When x=4.65 Y = X3 - 6(X) Y = 4.653 - 6(4.65) Y = 100.54 - 27.9 Y = 72.64 72.64 > 72 72.64 is too high so to 1 decimal place, the solution to the equation is 4.6.

The baby weighed a total of 283 ounces when delivered by the mother.

We must first convert the pounds to ounces and then add up the weights to get the total weight of the babies in ounces.

The total weight of Baby A was 73 ounces, or 4 * 16 + 9.

Baby B weighed 7 pounds, 8 ounces, or 7 x 16 x 8 = 120 ounces.

Baby C weighed 5 pounds, 10 ounces, or 5 x 16 x 10 = 90 ounces.

Let's now add the weights together:

73 ounces (Child A) + 120 ounces (Child B) + 90 ounces (Child C) = 283 ounces.

As a result, the baby weighed a total of 283 ounces when delivered by the mother.

The square root of 48 is nowhere near 12. That means that A and D are wrong. On a test that's an important consideration because if you have to guess, you've just cut the possibilities down to 2.

So the answer must  be B or C. Furthermore, you don't have to go to the trouble of factoring 48 to show that it is 4 sqrt(3). There's no other choice.

So what about x^5. 5 is an odd number. That means that one of the xs is left underneath the square root sign. That makes B incorrect. Without doing a calculation, I know that C is the answer.

Note

x^5 = x * x * x * x * x

The rule is for ever 2 factors that are the same, 1 factor is put in front of the square root sign and the other 1 is thrown out.
