Solve the following any quality and write the solution in set form and then graph the solution set

Answer:

5 ; 2.07 ; 1.85

Step-by-step explanation:

Given the data:

2, 3, 5, 6, 7

The range : ( highest - lowest)

The range = (7 - 2) = 5

Sample standard deviation :

sqrt[Σ(x - m)²/ (n - 1)]

The mean (m) = Σx / n

n = sample size = 5

Σx / n ;

(2+3+5+6+7) / 5

= 23 / 5

= 4.6

[(2-4.6)^2 + (3-4.6)^2 +(5-4.6)^2 + (6-4.6)^2+ (7-4.6)^2] / (5 - 1)

= 17.2 / 4

= 4.3

Sqrt(4.3) = 2.07

Population standard deviation :

sqrt[Σ(x - m)²/ n]

The mean = m = 4.6

n = sample size = 5

[(2-4.6)^2 + (3-4.6)^2 +(5-4.6)^2 + (6-4.6)^2+ (7-4.6)^2] / 5

= sqrt(17.2 / 5)

= sqrt(3.44)

= 1.8547 = 1.85

28 and 30 is the answer

f(x) = x^2 + 6x - 7

y = x^2 + 6x - 7

y = (x - 1)(x + 7)

x + 7 = 0

x = -7

x - 1 = 0

x = 1

The x-intercepts are -7 and 1.

Since the leading coefficient is a positive, the graph will point upwards.

So, the graph of the function is D.

Step-by-step explanation:

One can only buy integer numbers of packages of hotdogs, so the domain is integer values.

Since we "must" buy more than 0 packages, the appropriate domain specification is ...

Answer:

Which of the following expressions result in −4? Select three that apply. A −20⋅0.2 B −6⋅1.5 C −24⋅82 D −13⋅242 E 52⋅(−85) F 4⋅(−114)

Step-by-step explanation:

Answer:

F 4-(-114)

Step-by-step explanation:

Answer:

Y = x + 10

Slope - 1/2

y-intercept - (0,10)

Y = 2x + 12

slope 2/1

y intercept (0,10)

Y = 4 x + 14

Slope 4/1

Y intercept (0,14)

Step-by-step explanation:

The first questions answer:

Given (0, -4), 4x - y = 7. I converted the equation into slope intercept form and I got: y = 4x - 7. Once I had gotten that I put (0, -4) and the equation into Point-Slope Form and solved it: y - (-4) = 4(x + 0),  y + 4 =  4x,  y = 4x - 4 is the slope intercept form of your equation and point :)

Answer:

7/4

Step-by-step explanation:

[tex]x\cdot \frac{7}{4}=1\\\\x\cdot \frac{7}{4}\cdot \frac{4}{7}=1\cdot \frac{4}{7}\\\\x\cdot 1 = \frac{4}{7}\\\\x=\frac{4}{7}[/tex]

Answer:

The answer is [tex]\frac{4}{7}[/tex].

Step-by-step explanation:

Due to the end result being 1, we can sufficiently say it is neither -7/4 nor -4/7, due to a positive number multiplied by a negative number always equating to a negative number.

Therefore, using the Multiplicative Inverse Property, we can find the result by dividing 1 over [tex]\frac{7}{4}[/tex]:

[tex]\frac{1}{\frac{7}{4}}[/tex]

[tex]= \frac{4}{7}[/tex]

Hence, the answer is [tex]\frac{4}{7}[/tex].

Hope this helped!

Answer: 1/3

Step-by-step explanation:

Assume Jolene's DVDs are x.

Selena has twice as many DVDs as Jolene so Selena has 2x DVDs.

Jolene has 1/3 as many DVDs as Brodie which means that Brodie has 3 times as many DVDs as Jolene which is 3x.

Total DVDs = x + 2x + 3x

= 6x

Salena has 2x.

Fraction = 2x/6x

= 1/3

Answer:

5. 97

Step-by-step explanation:

Well, we know that all we have to do is add QRP and PRS. so 71+25 is 96 (but put 97). For the other one you can do 2x-5=x+1. Then you just solve for x. For the y value you do the same thing, 3y=5y+3. So, x=2 but y=1.5 but its not an answer choice... I know the second one didn't help you, sorry. :(

Answer:

You can get an idea of how much guaranteed lifetime income a given amount of savings will buy by going to this annuity payment calculator. Today, for example, $100,000 would get a 65-year-old man about $525 a month in lifetime income, while that amount would generate roughly $490 a month for a 65-year-old woman.

Answer: $8966.10

Step-by-step explanation:

The monthly payment with interest is 67.925. Multiply that by 12 for the 12 months in a year. You should get 815.10 as your yearly payment. And finally multiply 815.10 by 11 for the 11 years. You should get 8966.10 as your final answer. I hope this helps!

He already has $20 and the game costs $60.Each time he walks a dog he earn $5 so he needs to walk 8 more dogs(5×8=40)

Answer:

8 more dogs

Step-by-step explanation:

$60-$20 =$40

1 dog= 5 dollars

? =40 dollars

4o÷5=8

=8 dogs

Step-by-step explanation:

When f(x) = g(x), -3x + 8 = 7x - 2.

=> 10x = 10, x = 1.

The solution of the functions is 1.

The solution to functions f(x) = -3x + 8 and g(x) = 7x - 2  graphed by Carlos is x = 1

The given functions graphed by Carlos are:

f(x)  =  -3x  +  8

g(x)  =  7x  -  2

The solution to the functions is the point where the two functions intersect on the graph

To get the point where the two functions intersect, equate f(x) and g(x).

That is, f(x)  =  g(x)

-3x  +  8   =  7x   -  2

Collect like terms:

7x  +  3x  =  8  +  2

10x   =  10

Divide both sides by 10

10x / 10  =  10/10

x   =  1

The solution to functions f(x) = -3x + 8 and g(x) = 7x - 2  graphed by Carlos is x = 1

Answer:

179/495

Step-by-step explanation:

x = 0.3616161..........  ---------------(I)

Multiply by 1000

1000x = 361.616161......

Multiply (I) by 10

10x = 3.616161........
