The reason is because she didn't survey the school, but only surveyed her class, and to add to that It didn't say it was a random selection of students. Juliet concludes that short stories is the favorite type of book of the students in her school because 80% of the students in her class like short stories. Just because most of her class chose short stories she believes the rest of the school will have the same choice.

Because she only ask to her class and get 80%. If she wants to know the favorite type of book of the students in her school she needs to ask to the whole school

Use the equation for the surface area of a cylinder, SA = 2^r2 + 2arh, where r is

Alenkinab [10]

Answer:

Step-by-step explanation:

the given formula in the question is not correct

here is the correct formula

S. A. =2πr^2 +2πrh

given that S.A=207.24

radius r= 3in

207.24=2*3.142*(3)^2 +2*3.142*(3)h

207.24=56.556 +18.852h

207.24-56.556=18.852h

150.684=18.852h

h=150.684/18.852

h=7.99

Approximately the height is 8in

a line passes through (2, –1) and (8, 4). a. choose the correct equation for the line in point-slope form. b. what is the equati

LenaWriter [7]

In point slope form, required equation is given by (y - y1) = m(x - x1); where m = (y2 - y1)/(x2 - x1) = (4 + 1)/(8 - 2) = 5/6

Required equation is y + 1 = 5/6 (x - 2)

In standard form, 6y + 6 = 5x - 10 => 5x - 6y = 6 + 10 => 5x - 6y = 16

Draw graph of each equation. 2x+3y+18=0

Rasek [7]

Graph is attached has a negative slope of-2/3 and a y-intercept of -6

Step-by-step explanation:

The equation is 2x +3y +18 =0,that can be written in slope-intercept form as;

3y= -2x-18

y= -2/3 x- 6

Use a graph tool to plot the equation and visualize the graph as shown

Hence, the required inequality is x+y≤4, 7x+4y≤1150

<h2>What is inequality?</h2>

inequality, In mathematics, a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

<h3>How to solve?</h3>

Let x be the number of adults and y be the number of campers.

There are rooms for 450 people, so

x+y≤450.

Each adult costs $7, then x adults cost $7x.

Each camper costs $4, then y campers cost $4y.

There is a maximum budget of $1,150, so

7x+4y≤1,150

Hence, you get the system of two inequalities:

x+y≤4

7x+4y≤1150
