Answer:

a) The sold games of Jezebel had the greatest spread.

b) The middle 50% of the games sold by Colin has the least spread.

c) Jezebel sold more games than colin.

Step-by-step explanation:

Range is sued to calculate the spread of the given data.

Range is given by:

[tex]Range=Max\ Value-Min\ Value[/tex]

So,

Part a)

For Collin:

Range=21-3=18

For Jezebel:

Range=26-5=21

Part b)

Middle 50% of the values will be the values between 1st quartile and 3rd quartile

So, to find quartiles:

For Colin:

=3,9,9,14,15,16,17,20,21

The median is 15.

The lower half is 3,9,9,14

Q1 = (9+9)/2= 18/2 = 9

The upper half is 16,17,20,21

Q3 = (17+20)/2= 37/2= 18.5

The middle 50% is first quartile subtracted from third quartile

So, the spread is:

18.5-9=9.5

For Jezebel:

4,5,8,10,11,14,20,20,26

The median is 11.

The lower half is 4,5,8,10

Q1 = (5+8)/2=13/2=6.5

The upper half is 14,20,20,26

Q3 = (20+20)/2=40/2=20

The middle 50% values' spread is:

20-6.5=13.5

Part c) The answer to part a tells us that Jezebels sold games have more spread than Colin's sold games. Similarly the answer of part b tells us that the spread of middle 50% values of Jezebel's sold games was more than the spread of middle 50% values of Colin's sold games ..

Answer:

Each burrito platter costs $_31__ and each taco platter costs $_23__ .

Step-by-step explanation:

Let the cost of a burrito platter be x and the cost of a taco platter be y;

4 burrito platters and 5 taco platters would cost;

4x  + 5y = 239

3 burrito platters and 5 taco platters would cost;

3x + 5y = 208

We can solve the two equations simultaneously via elimination method. We subtract the two equations in order to eliminate y and solve for x;

4x - 3x = 239 - 208

x = 31

Using the first equation, substitute x = 31 and solve for y;

4(31) + 5y = 239

124 + 5y = 239

5y = 115

y = 23

The on second day and third day the amount of the helium gas will be left in the balloon gas will be 500 and 250 cubic cm respectively.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have:

A helium balloon is filled with 1,000 cm3 of helium.

First day of the balloon has 1000 cubic cm helium gas

Each day, the balloon loses half its helium.

After second day the amount of helium gas = 1000/2 = 500 cubic cm

After third day, the amount of helium gas = 500/2 = 250 cubic cm

Thus, the on second day and third day the amount of the helium gas will be left in the balloon gas will be 500 and 250 cubic cm respectively.

#SPJ2

Answer: 21

Step-by-step explanation:

we have two simple equations:

1) 70=100%

2) x=30%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

70/x=100%/30%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 30% of 70

70/x=100/30

(70/x)*x=(100/30)*x - we multiply both sides of the equation by

70=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x

70/3.33333333333=x

The fore, the answer is 21

Answer:

21

Step-by-step explanation:

30% of some quantity is equivalent to 0.30 times that quantity.

In this case, 30% of 70 is 0.30(70) = 21.

Answer:

Answer:

The measure of angle LMN is 68° ⇒ the last answer

Step-by-step explanation:

* Lets revise the properties of the rhombus

- The rhombus has 4 equal sides in length

- Every two opposite angles are equal in measure

- Every two adjacent angles are supplementary (their sum = 180°)

- The two diagonals bisect each other

- The two diagonals perpendicular to each other

- The two diagonals bisect the vertices angles

* Lets solve the problem

∵ LMNO is a rhombus

∴ ∠LMN and ∠MNO are adjacent angles

∴ ∠LMN and ∠MNO are supplementary

∴ m∠LMN + ∠MNO = 180°

∵ m∠MNO = 112°

∴ m∠LMN + 112° = 180° ⇒ subtract 112 from both sides

∴ m∠LMN = 68°

* The measure of angle LMN is 68°

Answer:

68

Answer:

rate per month = .01 agreed = r

Luckily they only ask for the first month so it is 0.01 * 20 .

Later months get more complicated and it is like paying off a mortgage with the term unknown but the rate and payment known.

Payment = principal value [ r / {1-(1+r)^-n } ]

100 = 2000 [ .01 / {1 - (1.01)^-n } ]

5 = 1/ {1 - (1.01)^-n }

.2 = 1 - (1.01)^-n

.8 = 1.01^-n

log .8 = -n log 1.01

n = 22.4 months :)

so over the almost two years pay 2240 total :)

* Hopefully this helps:) Mark me the brainliest:)!!!

Final answer:

For Sheila's first payment on her new computer financed at 12% annual interest with $100 monthly payments, she will pay $20 towards interest and the remaining $80 will go towards the principal.

Explanation:

Sheila bought a new computer for $2000 and agreed to finance it at 12% annual interest, with $100 monthly payments. To calculate the interest she will pay with the first payment, we need to find 1% of $2000 (since 12% per year is equivalent to 1% per month).

(1% of $2000) = 0.01 * $2000 = $20

Therefore, when Sheila makes her first monthly payment of $100, $20 will go towards interest, and the remaining $80 will reduce the principal on her loan.

Let a,b & c be the number of cookies Adrian, Bobby and Calvin baked respectively.

(a+b+c)/3 =138

(a+b)/2 =136

a+b=272

a=272-b

(b+c)/2 =125

b+c=250

c=250-b

Sub a=272-b and c=250-b into (a+b+c)/3 =138,

(a+b+c)/3 =138

[(272-b)+b+(250-b)]/3 = 138

272-b+b+250-b = 414

-b = -108

b=108

From the above,

a=272-b

=272-108

a=164

c=250-b

=250-108

c=142

∵ a=164

b=108

c=142

∴ Adrian baked 164 cookies.

Bobby baked 108 cookies.

Calvin baked 142 cookies.

Answer: Option C

domain: {x | x is a real number}; range: {y | y > 2}

Step-by-step explanation:

We have the function [tex]f(x) =(\frac{1}{6})^x + 2[/tex]

Note that f(x) is an exponential function.

By definition the exponential functions of the form [tex]a(b)^x +k[/tex]  have as domain all real numbers and as range {y | y > k}  if [tex]a>0[/tex], [tex]b>0[/tex]

Where a is the main coefficient, b is the base and k is the vertical displacement.

In this case [tex]k = 2[/tex], [tex]b=\frac{1}{6}[/tex], [tex]a=1[/tex]

Therefore the domain of f(x) is all real numbers and the range of f(x) is

{y | y > 2}

[tex]\bf \textit{area of a sphere}\\\\ SA=4\pi r^2~~ \begin{cases} r=radius\\ \cline{1-1} SA=64\pi \end{cases}\implies 64\pi =4\pi r^2 \\\\\\ \cfrac{64\pi }{4\pi }=r^2\implies 16=r^2\implies \sqrt{16}=r\implies 4=r[/tex]

The radius of the sphere will be 4 meters. Thus, the correct option is D.

Let r be the radius of the sphere. Then the surface area of the sphere will be given as,

SA = 4πr² square units

The surface area of the sphere is 64π square meters. Then the radius of the sphere is calculated as,

64π = 4 x π x r²

r² = 16

r = 4 meters

Thus, the correct option is D.

Answer:

x = - 2

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x) = x² - 2x + 6x + 4 = x² + 4x + 4 ← equating to 0

x² + 4x + 4 = 0 ← in standard form

(x + 2)² = 0 ← in factored form, thus

x + 2 = 0 ⇒ x = - 2

[tex]f(x + h) = \frac{4x + 4h}{1 - x - h}[/tex]

EXPLANATION

The given expression is

[tex]f(x) = \frac{4x}{1 - x} [/tex]

To find an expression for f(x+h), we substitute x+h, wherever we see x in the given expression.

This implies that,

[tex]f(x + h) = \frac{4(x + h)}{1 - (x + h)} [/tex]

The domain is {x I x ≠ 13} ⇒ the last answer

Step-by-step explanation:

* Lets talk about the composite function

- It is a function is found from two given functions by applying one

 function into the second function.

- The applying function is the domain of the second function

- (f °g)(x) means g(x) is applying into f(x)

* Lets solve the problem

∵ f(x) = x + 7

∵ g(x) = 1/(x -13)

- To apply g(x) into f(x) replace x in f(x) by g(x)

∴ f(g(x)) = f(1/(x - 13)) = 1/(x - 13) + 7

- The domain of the function is all values of x which make the function

  defined

- The domain is all real numbers except the value which makes

 the denominator = 0

- To find this value put the denominator = 0

∵ The nominator of (f ° g)(x) is x - 13

∴ Put x - 13 = 0

∴ x - 13 = 0 ⇒ add 13 to both sides

∴ x = 13

∴ The domain of (f ° g)(x) is all real numbers except x = 13

* The domain is {x I x ≠ 13}

To find the answer, I used:

Volume = Length • Height • Width

Each book in box 1 has a volume of 132 inches^3 and there are 16 of them, so I multiplied 132 inches^3 by 16 and got a total volume of 2,112 inches^3 in box 1

Each book in box 2 has a volume of 30 inches^3 and there are 30 of them, so I multiplied 30 inches^3 by 30 and got a total volume of 900 inches^3 in box 2

2,112 inches^3 is greater than 900 inches^3 so box 1 should be more than twice as big as box 2

2112 cubic inches.

To determine which of the two boxes is larger, we need to calculate the volume of each box. For the first box, containing books each measuring 3/2 in by 8 in by 11 in, the volume of one book is calculated as:

For the second box, containing books each measuring 3/4 in by 5 in by 8 in, the volume of one book is calculated as:

Comparing the two totals, the second box, with a total volume of 4500 cubic inches, is larger than the first box, which has a total volume of 2112 cubic inches. Hence, we know that the second box is larger because it has a greater total volume.

A) v1 is not perpendicular to v2

EXPLANATION

Two non-zero vectors are orthogonal or perpendicular if their dot product is zero.

In other words,if two non-zero vectors are not orthogonal or perpendicular then their dot product is not equal to zero.

From the question v1 and v2 are non-zero vectors and their dot product is not equal to zero.

This tells us that, the two vectors are not perpendicular.

The correct choice is A.

Answer:

A) v1 is not perpendicular to v2

Step-by-step explanation:

This proves that the test for orthogonality fails (doesn’t equal zero) meaning that V1 is not perpendicular to V2.

C. Factoring a perfect square trinomial.

EXPLANATION

Observe that the left hand side is a perfect square trinomial.

In other words, the left hand side is of the form,

[tex] {m}^{2} + 2mn + {n}^{2} [/tex]

which can be factored as:

[tex] {m}^{2} + 2mn + {n}^{2} = {(m + n)}^{2} [/tex]

When we factor the perfect square trinomial on the left hand side, we obtain:

[tex]( x + \frac{b}{2a} )^{2} = - \frac{c}{a} + ( \frac{b}{2a} )^{2}[/tex]
