First you need the midpoint formula. (x1+x2 divided by 2)and (y1+y2 divided by 2) Which would look like this.. 13+-6=7 and 7 divided by 2 is 3.5.... 8+-6=2 And 2 divided by 2 is 1. so your answer is (3.5, 1)

Let F(x,y)=1+sqrt(4-y^2). . (a) Evaluate F(3,1). (b) Find and sketch the domain of F. (c) Find the range of F
charle [14.2K]
The goal of this function is to get  a positive value under the square root sign so that the value would not be invalid. Evaluating F(3,1), the value is 1 + <span>sqrt(4-1^2) or equal to 1 + sqrt of 3.</span> In this case, the domain would be x equal to any numbers and the range equal to numbers from -2 ≤ y ≤ 2.

Write the equation of each ellipse in standard form with the given characteristics.
Eddi Din [679]

Answer:

Step-by-step explanation:

The foci are horizontally aligned.

horizontal ellipse:

(x-h)²/a² + (y-k)²/b² = 1

center (h,k)

vertices (h±a,k)

length of minor axis = 2b

foci (h±c,k), c² = a²-b²

Apply your data and solve for h, k, a, and b.

foci (±3√19, 6)

h = 0

k = 6

Length of minor axis = 2b = 10

b = 5

foci (h±3√19, 6)

c = 3√19

c³ = a² - b²

171 = a² - 25

a²  = 196

x²/196 + (y-6)²/25 = 1

What are the relationships among radii, chords, tangents, and inscribed and circumscribed angles?
Mars2501 [29]
These are all parts of circles.

A radius is the distance from the center of a circle to the edge.

A chord is a line segment from 2 different places on a circle.

A tangent is a line that touches the edge of a circle in only 1 place.

Inscribed angles are inside a circle and circumscribed angles are on the outside of a circle.

According to a survey, 62% of murders committed last year were cleared by arrest or exceptional means. Fifty murde committed las
alexira [117]

Answer:

a) The probability that exactly 41 of the murders were cleared is 0.0013

b) The probability that between 36 and 38 of the murders, inclusive, were cleared is 0.0809.

c) Yes, it would be unusual

Step-by-step explanation:

Let p=62% considered as the probability of having a commited that is cleared by arres or exceptional means. We assume that choosing each of the 50 commited is independent of each choose. Then, let X be the number of cleared. In this case, X is distributed as a binomial random variable. Recall that, in this case,

P(X=k) = \binom{50}{k} p^{k}(1-p)^{50-k} for0\leq k \leq 50, with p=0.62

a) We have that

P(X=40) = \binom{50}{40} p^{40}(1-p)^{50-40} =0.001273487

b) We are asked for the following

P(36\leq X \leq 38) = P(X=36)+P(X=37)+P(X=38) = 0.080888936&#10; (The specific calculation is omitted.

c) We will check for the following probability P(X\leq 19)

P(X\leq 19 ) = \sum_{k=0}^{19} P(X=k) = 0.000499222&#10;

Given that the probability of this event is really close to 0, it would be unusual if less than 19 murders are cleared.
