use the equation (y-y)=m(x-x). for example with the first equation: (y-7)=-4(x-2) distribute the slope into the (x-2). this will give you (y-7)=-4x+8. then you add the 7 to both sides to cancel it. this gives you y=-4x+15. hope this helps!! :)

A company has a manufacturing plant that is producing quality jackets. They find that in order to produce 150 jackets in a month

Masja [62]

Answer:

$y = 14x + 3400$

Step-by-step explanation:

Represent

- number of jackets with x

- costs of jackets with y

So, we have:

$(x_1,y_1) = (150,5500)$

$(x_2,y_2) = (370,8580)$

Required

Write an equation in form of y = mx + b

First, we need to determine the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{8580 - 5500}{370 - 150}$

$m = \frac{3080}{220}$

$m = 14\\$

The equation is calculated using:

$y-y_1 = m(x - x_1)$

Where

$m = 14\\$

$(x_1,y_1) = (150,5500)$

So, we have:

$y - 5500 = 14(x - 150)$

$y - 5500 = 14x - 2100$

Make y the subject

$y = 14x - 2100 + 5500$

$y = 14x + 3400$

A cone-shaped tent has a diameter of 12 ft and a height of 6 ft. What is the approximate volume of the tent? Question 2 options:

inessss [21]

Answer:

Step-by-step explanation:

The formula of volume of cone is

V=\frac{1}{3}\pi r^{2} h

where, r is the radius

we have given diameter = 12 =2r

r=6 ft

h is the height h=6 ft

\pi =3.14

Substitute the value in the formula,

V=\frac{1}{3}\pi r^{2} h

V=\frac{1}{3}\times (3.14)\times 6^{2}\times 6

V=\frac{1}{3}\times 3.14\times 36\times 6

V=226.08 ft^3

Therefore, The volume of cone is 226.08 cubic ft.

Assume that when Human Resource managers are randomly selected, 62% say job applicants should follow up within two weeks. If 25

stellarik [79]

Using the binomial distribution, it is found that there is a 0.1008 = 10.08% probability that exactly 18 of them say job applicants should follow up within two weeks.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

The values of the parameters are given as follows:

n = 25, p = 0.62.

The probability that exactly 18 of them say job applicants should follow up within two weeks is P(X = 18), hence:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 18) = C_{25,18}.(0.62)^{18}.(0.38)^{7} = 0.1008$

0.1008 = 10.08% probability that exactly 18 of them say job applicants should follow up within two weeks.

Help with steps <br>questions on image

Sveta_85 [38]

Answer:

Step-by-step explanation:

all odd numbers possible: 1, 3, 5, 7

__ __ __ __

there are 4 possibilities for the first blank

for the second blank there are 4-1 = 3 possibilities as one of the numbers will have been used

for the third blank there are 4-2 = 2 possibilities as 2 of the numbers have been used

for the last blank there is only 1 possibility

so the number of solutions possible is 4 x 3 x 2 x 1 = 24
