Properties of a circle:

ExtremeBDS [4]

Tangent is a line that touches the circle at one point going infintiely in both directions

chord is a line that goes from one side of the circle to the other and stays inside the circle, an example would be the diameter which is the longest chord in the circle

secant is a line that goes through the circle at 2 points, it's like a chord but it extends outside the circle

arc length is a section of the circumference
it's like the length of the crust when you cut a slice of pie or the crust of a pizza

A bouquet of flowers contains a total of 24 red and white roses. The number of red roses is 4 less than three times the number o

geniusboy [140]

Answer:

White roses - 7

Red roses - 17

Step-by-step explanation:

Set up proportional equations

White roses = x

Red roses = 3x - 4

Set equal to 24

x + 3x - 4 = 24

4x - 4 = 24

4x = 28

x = 7

x is white roses, so there are 7

Plug x value into red rose equation

3(7)-4

21-4 = 17 red roses

Check

17+7 = 24

HELP ASAP ...........

dedylja [7]

Answer:

Step-by-step explanation:

Given

y - 2x - 8 = 0 ( add 2x + 8 to both sides )

y = 2x + 8 → (1)

y² + 8x = 0 → (2)

Substitute y = 2x + 8 into (2)

(2x + 8)² + 8x = 0 ← expand left side using FOIL and simplify

4x² + 32x + 64 + 8x = 0

4x² + 40x + 64 = 0 ( divide through by 4 )

x² + 10x + 16 = 0 ← in standard form

(x + 8)(x + 2) = 0 ← in factored form

x + 8 = 0 ⇒ x = - 8

x + 2 = 0 ⇒ x = - 2

Substitute these values into (1) for corresponding values of y

x = - 8 : y = 2(- 8) + 8 = - 16 + 8 = - 8 ⇒ P (- 8, - 8)

x = - 2 : y = 2(- 2) + 8 = - 4 + 8 = 4 ⇒ Q (- 2, 4 )

Calculate the length of PQ using the distance formula

PQ = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = P (- 8, - 8) and (x₂, y₂ ) = Q (- 2, 4 )

PQ = $\sqrt{(-2-(-8))^2+(4-(-8))^2}$

= $\sqrt{(-2+8)^2+(4+8)^2}$

= $\sqrt{6^2+12^2}$

= $\sqrt{36+144}$

= $\sqrt{180}$

= $\sqrt{36(5)}$

= $\sqrt{36}$ × $\sqrt{5}$

= 6 $\sqrt{5}$ → A

According to a recent New York Times poll, 25% of the public have responded to a telephone call-in

ArbitrLikvidat [17]

Answer:

Probability that exactly two people out of a randomly chosen group of five people have responded to a telephone call-in poll is 0.264.

Step-by-step explanation:

We are given that according to a recent New York Times poll, 25% of the public have responded to a telephone call-in poll.

Also, five people have people have been randomly selected.

The above situation can be represented through binomial distribution;

$P(X = r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x=0,1,2,3,.......$

where, n = number trials (samples) taken = 5 people

r = number of success = exactly two

p = probability of success which in our question is probability that

public have responded to a telephone call-in poll, i.e; p = 25%

Let X = Number of people who have responded to a telephone call-in poll

So, X ~ Binom(n = 5, p = 0.25)

Now, probability that exactly two people out of group of five people have responded to a telephone call-in poll is given by = P(X = 2)

P(X = 2) = $\binom{5}{2} \times 0.25^{2} \times (1-0.25)^{5-2}$

= $10 \times 0.25^{2} \times 0.75^{3}$

= 0.264

Therefore, the probability that exactly two people out of a randomly chosen group of five people have responded to a telephone call-in poll is 0.264.
