A total of 250 people were surveyed about whether or not each person carries a cell phone. The results are shown below in the relative frequency table. Which statement is correct

Answer:

subtraction

Step-by-step explanation:

its subtraction because if you do 62.5-2.5 it = 60 and then 60-2.5=57.5 57.5-2.5=55 55-2.5=52.5 52.5-2.5=50 50-2.5= 47.5 47.5-2.5 = 45 s so it was 7 or 8 years ago idk count them see how many times i did it

Answer: See explanation

Step-by-step explanation:

Since Jack receives 55 rewards points just for signing up and earns 12.5 points for each visit to the movie theater and needs at least 205 points for a free movie ticket.

The inequality which can be used to determine v, the number of visits Jack can make to earn his first free movie ticket will be:

55 + 12.5v ≥ 205

12.5v ≥ 205 - 55

12.5v ≥ 150

v ≥ 150/12.5

v ≥ 12

The number of visits that Jack can make to earn his first free movie ticket will be at least 12 visits

Answer:

a = 2

b = 5

c = -12

The discriminant is sqr root (b^2 - 4*a*c)

= sqr root (25 -4 * 2 * -12)

= sqr root (25 + 96)

= sqr root (121)

Answer:

height x=21.5cm

Step-by-step explanation:

Surface area = 2+ area of triangles + area of the 3 rectangles

SA = 204

204 = 4*3 + x*5 + 5*4 + x*3

204 = 12 +20 +8x

204 -12-20 = 8x

172/8 = x

21.5 = x

good answer thats was a very helpful answer

Answer:

While imaginary numbers offers unique insights, we live in a real world. Real numbers provide a model that fits many (most) of the day to day situations people encounter every day. Understanding real numbers and having a sense for what they are and ow they can be used to model 'the real world' is a skill every intelligent person must master.

Answer:

It's B.9

Step-by-step explanation:

Because

11+9=20

20+9= 29

29+9= 38

The common difference is positive because the arithmetic sequence is increasing.

Answer:

B. arithmetic sequence; 9

Step-by-step explanation:

An arithmetic sequence is a sequence where there is a common difference between each term. A common difference is a number that is added to the previous term to get the current term. For a sequence to be considered arithmetic this common difference must remain constant. This sequence is arithmetic because each time 9 is added to the previous term to get the next one. So the common difference is 9 and B is correct.

Answer:

x=20

Step-by-step explanation:

12.5/1.25=10

This means that to get from Figure B to A, you would need to divide by 1.25

So to get from Figure A to B, you would have to multiply by 1.25

16*1.25=20

Answer: B.

Step-by-step explanation:

Answer:

The given line y = -2x +30 is a straight line as it is written in the

form y = mx + b.

The graph of the line y = -2x +30 is also straight and attached below.

Step-by-step explanation:

Given the equation

y = -2x +30

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept

Writing the equation in the slope-intercept form

y = -2x +30

y = mx + b

Thus,

m = -2

b = 30

Thus, the given line y = -2x +30 is a straight line as it is written in the

form y = mx + b.

The graph of the line y = -2x +30 is also straight and attached below.

Answer:

How does knowing one linear factor of a polynomial help find the other factors?

Step-by-step explanation:

f(x)=(x−3)(x−1)(x+2)(x+6)

f(x)=(x−2)(x−2)(x+3)(x+5)

f(x)=(x−5)(x−3)(x+2)(x+2)

f(x)=(x−8)(x−1)(x+3)(x+5)

f(x)=(x−2)(x−1)(x+4)(x+4)

Correct answer:

f(x)=(x−2)(x−2)(x+3)(x+5)

Explanation:

We begin by attempting to find any rational roots using the Rational Root Theorem, which states that the possible rational roots are the positive or negative versions of the possible fractional combinations formed by placing a factor of the constant term in the numerator and a factor of the leading coefficient in the denominator.

That was a lot of wordage in one sentence, so let's break that down.  We begin with our polynomial.

f(x)=x4+4x3−13x2−28x+60

The constant term is the term without a variable (just a plain number).  In our case the constant is 60.  What are the possible factors of 60?

1,2,3,4,5,6,10,12,15,20,30,60

The leading coefficient is the number in front of the largest power of the variable.  When the terms are listed in descending order (highest to lowest power), the leading coefficient is always the first number.  In our case the leading coefficient is hard to spot.  Since there is no number in front of x4, the coefficient is 1 by default.

This is nice because the only factor of 1 is well ... 1.

We then create all the possible fractions with a factor of the constant in the numerator and a factor of the leading coefficient in the denominator.  This actually isn't as bad as it could be since our only possible denominator is 1.  Any fraction with a denominator of 1 is just the numerator.  Therfore, our possible "fractions" are simply

1,2,3,4,5,6,10,12,15,20,30,60

However, we must consider the positive or negative versions of these, so our final list of possible rational roots is

±1,±2,±3,±4,±5,±6,±10±,1±2,±15,±20,±30,±60

Unfortunately, this is where the process (at least without the assitance of a graphing calculator) becomes less fun.  Using synthetic division, we must simply try each possible root until we have success. There's really no consistent rule to tell us where to start. Generally starting with the smaller whole numbers is best because the synthetic division is easier.  Therefore, we could begin with 1 then proceed to −1,2,−2, etc.  

For the sake of keeping this explanation as short as possible, I am going to skip straight to 2, where we will first find success.

Therefore, 2 is a root.  However, it is always important to check to see if a root is in fact a double root (it works twice).  Therefore, let's try it one more time.

2 does in fact work twice and is thus a double root.  Since we only have three terms remainng, we can convert from synthetic back to an algebraic expression.

f(x)=x2+8x+15

We can then factor.

f(x)=(x+3)(x+5)

Writing our root of 2 as an algebraic expression gives (x−2).  Since we have double root, we need two of these.  Therfore, our final factored expression is.

f(x)=(x−2)(x−2)(x+3)(x+5)
