Answer:

x=-2

Step-by-step explanation:

Given points are (-2,2) and (-2,-3).

Now we need to find equation of the line passing through the given points.

So let's begin by finding slope

$m=\frac{\left(y_2-y_1\right)}{\left(x_2-x_1\right)}=\frac{\left(-3-2\right)}{\left(-2-\left(-2\right)\right)}=\frac{\left(-5\right)}{\left(-2+2\right)}=-\frac{5}{0}$

which is undefined. That means graph of the line must be vertical as you can see that in given points, x-value is not changing.

Equation of vertical line is given by x=k where k is the fixed value of x-coordinate.

x-coordinate is -2 in given points.

Hence final equation is x=-2.

Answer:

312

Step-by-step explanation:

T.S.A : ( 2 × L × w ) + ( 2 × h × w ) + ( 2 × L × h ) = Area

9 - 3 = 6 - 3 = 3

( 2 × 12 × 3 ) + ( 2 × 8 × 3 ) + ( 2 × 12 × 8 ) = Area

72 + 48 + 192 = 312

Please help me I don't understand this at all

saveliy_v [14]

Answer:

a) θ = $\frac{4}{3}\pi$ b) r = 31.27 inch

Step-by-step explanation:

(a)

area of sector: $\frac{1}{2}$ * r² * θ

384 = $\frac{1}{2}$ * r² * θ

384 = $\frac{1}{2}$ * (24)² * θ

θ = 384/288

θ = $\frac{4}{3}\pi$

(b)

384 = $\frac{1}{2}$ * r² * $\frac{\pi }{4}$

r² = 384 * 2 * $\frac{4}{\pi }$

r² = 977.848

r = √977.848

r = 31.27 inch

A florist uses 225 branches of winterberry to make 75 wreaths. Based on the ratio or unit rate, how many branches of winterberry

kondaur [170]

Answer:

the number of branches required to use 25 wreaths is 75 branches

Step-by-step explanation:

Given that

The florist used 225 branches of winterberry for making 75 wreaths

First we have to compute the unit rate or the ratio

= 225 ÷ 75

= 3 : 1

Now the number of branches required to use 25 wreaths is

= 3 × 25

= 75 branches

Hence, the number of branches required to use 25 wreaths is 75 branches

A policyholder has probability 0.7 of having no claims, 0.2 of having exactly one claim, and 0.1 of having exactly two claims. C

Colt1911 [192]

Answer:

0.89.

Step-by-step explanation:

So, we are given the following data or parameters or information which is going to aid in the solution to this question or problem. So, the data or parameters are;

(1). "probability 0.7 of having no claims, 0.2 of having exactly one claim, and 0.1 of having exactly two claims."

(2). " distributed on the interval [0,60] and are independent."

(3). "The insurer covers 100% of each claim."

So, taking (1) above we will have;

(Total probability= 0.7 + 0.2 + 0.1 = 0.1)

A = { (0.7 × 0)^2 + (0.2 × 1)^2 + ( 0.1 × 2)^2 =( 0.4) +( 0.4) = 0.8.

0.8 + total probability = 0.8 + 0.1 = 0.9.

So, from the question, we are to "Calculate the probability that the total beneﬁt paid to the policyholder is 48 or less."

Hence, P< 48/A = P < 48/0.9 = P < 53.33.

Thus, 53.33/60 = 0.89.
