What is the length of EF if ABC is similar to DEF
A. 22 units
B18 units
C. 32 units
D. 2 units​

Answer:

1555 people

Step-by-step explanation:

First, average the votes for polar bears.

(46 + 43 + 49)/3 = 46

Next, make the variable x equal to the estimate of the number of people who will prefer polar bear out of the 3380 people and set up your proportion equation.

x/3380 = 46/100

x = 1554.8

Round to the nearest whole number to get 1555.

Eucardo's collection of butterflies: 12+2x

Answer:

13.9

Step-by-step explanation:

3rd side = a

a² + b² = c²

a² + 8² = 16²

a² + 64 = 256

a² = 192

[tex]\sqrt{a^2} =\sqrt{192}[/tex]

a = 13.856

Rounded to tenths:

13.9

The correct interpretation of the interval is:

B. We are 95 percent confident that the difference in population means for miles traveled by the two companies is between 1.86 miles and 2.15 miles.

The conditions for inference that have been met are: D. I and III only.

For the first question, the correct interpretation of the confidence interval is:

B. We are 95 percent confident that the difference in population means for miles traveled by the two companies is between 1.86 miles and 2.15 miles.

This interpretation reflects the fact that the confidence interval was constructed based on the sample means, but it provides an inference about the population means of the two companies.

For the second question, the conditions for inference that have been met are:

D. I and III only

I. The data were collected using a random method.

This ensures that the samples are representative of the population.

III. Each sample size is large enough to assume normality of the sampling distribution of the difference in sample means.

This condition implies that the sample sizes are sufficiently large to rely on the central limit theorem, which states that the sampling distribution approaches a normal distribution as the sample size increases.

Condition II, which states that each sample size is less than 10 percent of the population size, is not explicitly mentioned in the question. Therefore, we cannot assume that this condition has been met.

Answer:

D. Precipitation

Step-by-step explanation : Gravity causes precipitation to fall from clouds and water to flow downward on the land through watersheds. Energy from the sun and the force of gravity drive the continual cycling of water among these reservoirs. As the water is heated, it changes state from a liquid to a gas.

The answer i got was B

Answer:

392 square units

Step-by-step explanation:

We can make 2 right trapezoids out of this shape.

The area of a trapezoid would be 1/2×(b1+b2)×h or (b1+b2)×h ÷ 2.

If we do 1 half it would be 1/2×(14+14)×14 = 196

Now if we multiply by 2 (because we have 2 trapezoids) it would be 392.

Answer:

y = 1/4 (x-4)² - 7

Step-by-step explanation:

Point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6

√(x-4)²+(y- -8)² = √(y- -6)²

(x-4)² + (y+8)² = (y+6)²

(y+8)² - (y+6)² = (x-4)²

(y²+16y+64) - (y²+12y+36) = (x-4)²

y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²

4y = (x-4)² - 28

y = 1/4 (x-4)² - 7

standard formula of parabola: y = a(x-h)² + k      (h,k): vertex (4,-7)

The value of equation of parabola is,

⇒ y = 1/4 (x-4)² - 7

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.

Now,

Let a point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6

Hence, We can formulate;

⇒ √(x-4)²+(y- (-8))² = √(y- (-6))²

⇒ (x-4)² + (y+8)² = (y+6)²

⇒ (y+8)² - (y+6)² = (x-4)²

⇒ (y²+16y+64) - (y²+12y+36) = (x-4)²

⇒ y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²

⇒ 4y = (x-4)² - 28

⇒ y = 1/4 (x-4)² - 7

Thus, The value of equation of parabola is,

⇒ y = 1/4 (x-4)² - 7

Answer:

[tex]\frac{4\sqrt{7}}{7} \text{ and } \frac{3\sqrt{7}}{7}[/tex]

Step-by-step explanation:

if [tex]\sec x = \frac{4}{3}[/tex], then that means that it is the angle of a right triangle with the hypotenuse equal to 4 and one of the legs (specifically the adjacent leg) equal to 3, since sec(x) is defined as hypotenuse over the adjacent side.

The other leg (specifically the opposite one) will be equal to [tex]\sqrt{16-9} = \sqrt{7}[/tex] by the pythagorean theorem, so csc(x) = hypotenuse over opposite side = [tex]\frac{4}{\sqrt{7}}=\frac{4\sqrt{7}}{7}[/tex].

cot(x) is defined as adjacent over opposite, which is equal to [tex]\frac{3}{\sqrt{7}}=\frac{3\sqrt{7}}{7}[/tex]

That means that the first option, the leftmost one, is correct.

Hope this helps! Have an Amazing day!!

Answer:

√5

Step-by-step explanation:

Remark

The distance formula is d = sqrt( (x2 - x1)^2 + (y2 - y2)^2  )

Givens

x2 = 2

x1 = 1

y2 = 3

y1 = 5

Solution

d = sqrt( (2 - 1)^2 + (3 - 5)^2 )

d = sqrt( (1)^2 + (-2)^2 )

d = sqrt( 1 + 4)

d = sqrt(5)

4/3*pi*512

2048/3 pi

This is the volume of the whole sphere but we only need half so we can just divide by 2.

Answer:

Step-by-step explanation:

I think it is helpful to set this up as a proportion as it is the easiest way in my opinion.

1st step: 396/18 and x/11

This is the way you set up the proportion.

2nd Step: You would have to multiply 396 and 11 then divide the value by 18.

396x11 = 4,356

4,356/18 = 242

x=242 Dollars
