Someone help me please.. I need the slope, y intercept and x intercept

Suppose that the cost of producing x tablets is defined by c(x)= 200 + 10x + 0.2x squared* where x represents the number if tabl

sammy [17]

we are given

$C(x)=200+10x+0.2x^2$

part-A:

Since, x is number of tablets

C(x) is cost of producing x tablets

so, vertical box is C(x)

so, we write in vertical box is "cost of producing x tablets"

Horizontal box is x

so, we write in horizontal box is "number of tablets"

part-B:

we have to find average on [a,b]

we can use formula

$\frac{C(b)-C(a)}{b-a}$

we are given point as

a: (15 , 395)

a=15 and C(15)=395

b: (20, 480)

b=20 , C(20)=480

now, we can plug values

$=\frac{480-395}{20-15}$

$=17$ ...........Answer

part-c:

we have to find average on [b,c]

we can use formula

$\frac{C(c)-C(b)}{c-b}$

we are given point as

b: (20, 480)

b=20 , C(20)=480

c:(25,575)

c=25 , C(c)=575

now, we can plug values

$=\frac{575-480}{25-20}$

$=19$ ..............Answer

In a class of 40 students, 5 like neither Nokia nor

STatiana [176]

Answer:

<em><u>The number of students that like only Nokia </u></em>

Step-by-step explanation:

consider N the number of students who like Nokia → N=?

T the number of students who like Techno → T=35

Statement 1: In a class of 40 students, 5 like neither Nokia nor Techno

we can translate it like this: 35 student like Nokia or Techno

we can note it like this : T∪N= 35

Statement 2: 30 like Techno and Nokia

we can note it : T∩N = 30

using a rule concerning the number of element of a set :

T∪N = N + T - T∩N

then

35 = N + 35 - 30

⇒ N - 30 = 0

⇒ N = 30

True or false: the value of theta represents the distance from a point to the origin when plotting a point in polar coordinates

SOVA2 [1]

False. The value of theta is the angle measured counterclockwise that the vector makes with respect to the positive x-axis.

Which statements are true given the histogram? Check all that apply.

vova2212 [387]

Answer:

(a)The histogram is symmetrical. FALSE

(b) The histogram is evenly distributed. FALSE

(c) The cluster from 4 p.m.-10 p.m. means that most of the texts were sent in the afternoon and evening. TRUE

(d) More texts were sent from 6 p.m.-8 p.m. than from 8 p.m.-10 p.m. FALSE.

(e)The peak from 4 p.m.-6 p.m. means that the highest number of texts was sent during this interval. TRUE

Step-by-step explanation:

(a)The histogram is symmetrical.

FALSE, as the histogram has no line of symmetry.

(b) The histogram is evenly distributed.

FALSE, the histogram is not evenly distributed as there is no data in the

10: AM to 3:00 PM slot.

(c) The cluster from 4 p.m.-10 p.m. means that most of the texts were sent in the afternoon and evening.

TRUE, the data shows that the most texts were sent in afternoon and evening as it has the highest peaks in the given slot.

(d) More texts were sent from 6 p.m.-8 p.m. than from 8 p.m.-10 p.m.

The number of texts sent from 6 p.m.-8 p.m = 19

The number of texts sent from 8 p.m.-10 p.m = 29

But, 19 < 29

Hence, the given statement is FALSE.

(e)The peak from 4 p.m.-6 p.m. means that the highest number of texts was sent during this interval. TRUE, the highest peak indicates the highest number of texts sent in the given interval.
