Answer:

Population - All 5.16 billion mobile phone users

Sample - subset of 1000 chosen from 5.16 billion

Variable - white and black mobile preference

Parameter - statistical characteristics of the population

Statistic - statistical characteristic of the sample ; 23.6% white preference ; 34.6 black preference

Data - facts and figures gathered for the study

Step-by-step explanation:

The population is the total observations who fit into a certain area of interest.

Sample refers to subset of the population which is meant to be representative of the larger population.

Variable refer to groups of characteristics with relates to observations within a dataset.

Parameter - statistical characteristics of the population

Statistic - statistical characteristic of the sample

Data - facts and figures gathered for the study

Answer:

The total money the coach will need for 40 basketballs will be 40 times price of one basketball.

Thus we need to find the price of one basketball.

$27 for 3 basketballs

Thus for one basketball, [tex]\frac{27}{3}[/tex] Which gives us,

'9'.

So for 40 basketballs 40 * $9

Which gives us $360.

The total money needed for sneakers is 7 times the cost of one sneaker.

So, we need to find the cost of 1 sneaker

which is [tex]\frac{90}{5}[/tex]  which gives us,

$18.

Thus total amount of money  needed for sneakers is 9 * $18 which gives us

$162

So total amount the coach has to pay is $360+$162 (total cost of basketballs + total cost of sneakers)

=$552

Therefore, total amount the coach has to pay is $552

66 are chocolate. 120x1.45 66

The number of cupcakes sold that day was chocolate flavored will be 54.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol '%' is used to symbolize it.

A bakery sold a total of 120 cupcakes in a day, and 45% of them were chocolate flavored.

Then the number of cupcakes sold that day were chocolate flavored will be

Let x be the number of the cupcakes sold that day that was chocolate flavored.

x = 45% of 120

x = 0.45 × 120

x = 54

Thus, the number of cupcakes sold that day was chocolate flavored will be 54.

Answer:

choose "infinitely more solutions"

Step-by-step explanation:

Let's solve this system by substitution method

y+1=2x

- 1 = - 1

y = 2x -1   <-- sbstitute this in the next equation

---------------------------------------------------------------------------------

    5y+5 = 10x

5(2x -1) + 5 = 10x

10x -5 + 5 = 10x

10x + 0= 10x

- 10x = -10x

0 = 0      <-- infinitely more solutions

Answer:

The point after the reflection of (-4,-3) across the y-axis is:

Hence, option B is correct.

Step-by-step explanation:

When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.  

Thus,  

The rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

In our case, we are given the point (-4, -3)

Let say the point is A(-4, -3)

Thus, using the rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

A(-4, -3) → A'(-(-4), -3) → A'(4, -3)

Therefore, the point after the reflection of (-4,-3) across the y-axis is:

Hence, option B is correct.

Answer:

b(1) = -3

b(n) = b(n-1) + 2

Step-by-step explanation:

Notice that there is a common difference in the sequence : each term is the previous one PLUS 2. Then the common difference "d" is 2 making this sequence an arithmetic sequence

b(1) = -3

b(n) = b(n-1) + 2

Answer:

$31.5

Step-by-step explanation:

X * 5% = $1.50

X = $1.50 / 5%

Or by using simple rule of three:

If 5% is $1.50

Then 100% is X

So you obtain = $30

Now you just need to sum The net prices and the taxes

Net + tax = Total Charge

$30 + $1.5 = $31.5

Step-by-step explanation:

3x+8=-4

Subtract 8 from both sides.

3x+8−8=−4−8

3x=−12

Step 2: Divide both sides by 3.

3x=−12

3       3

x=−4

Answer: Tyler's work is incorrect because when subtracting 8 from both sides of the equation, he didn't subtract it from -4. If he subtracted 8 from -4, it would've been 3x=-12.

The correct answer is x = -4

Step-by-step explanation:

you get x = -4 by subtracting 8 from each side of the equation, resulting in 3x = -12

then you divide both sides by 3, leaving you with x = -4

Answer: 15 second

Step-by-step explanation:

Amy to be at the start point is 400 seconds and for Joey to be at the start point is 333.3 seconds, in that time Joey finished the 10 turns, and Amy had ended the 12.

Joey starts running at v₁ = 10 m/sec  

Amy starts running at v₂ = 12 m/sec

we know that d = v [tex]*[/tex] t then t = d/v

Joey will take 400 / 10 = 40 seconds

Amy will take 400 / 12 = 33.33 seconds

To check  Joey  10 [tex]*[/tex] 40 = 400

And the Amy 12 [tex]*[/tex] 33.33 = 333.3

That means that time required for Amy to be at the start point is 400 seconds and for Joey to be at the start point is 333.3 seconds, in that time Joey finished the 10 turns, and Amy had ended the 12.

Therefore, 12 seconds elapse before Amy passes Joey on the track.

Answer:

x = 1

Step-by-step explanation:

It is given that,

∠A and ∠B are vertical angles.

∠A = (5x – 4) and ∠B = (2x – 1)

We need to find the value of x.

We know that, the vertical angles are equal. So,

∠A=∠B

(5x – 4)=(2x – 1)

Taking like terms together,

5x-2x = 4-1

3x=3

x = 1

So, the value of x is equal to 1.

$2,208

Step-by-step explanation:

In order to calculate her total pay for the month we simply need to use the hours provided in the question, multiply each amount of hours by they pay rate for that day/night. Finally, we add all of the products together to get the final pay for the month.

6 * (4*14) = 336

3 * (8 * 14) = 336

3 * (10 * 14) = 420

5 * (6 * 18) = 540

4 * (8 * 18) = 576

336 + 336 + 420 + 540 + 576 = $2,208

Finally, we can see that her total pay for the month is $2,208

Answer:

triangle

Step-by-step explanation:

Answer:

x + 6 + x + 6 + x + 6 + x + 6 + x + 6 x + 6 + x + 6 + x + 6 = 120

aka 8(6 + x) = 120

48 + 8x = 120

you want to get 8x on one side so you will subtract 48 on both sides - whatever you do to obe side you must do on the other side.

8x = 72

now you want the x by its self so to undo multiplication you need to divide, and divide on both sides.

Answer:

6

Step-by-step explanation:

Greatest common factor (GCF) of 42 and 60 is 6.

As the numbers get larger, or you want to compare multiple numbers at the same time to find the GCF, you can see how listing out all of the factors would become too much. To fix this, you can use prime factors.

List out all of the prime factors for each number:

Prime Factors for 42: 2, 3, and 7

Prime Factors for 60: 2, 2, 3, and 5

Now that we have the list of prime factors, we need to find any which are common for each number.

Looking at the occurences of common prime factors in 42 and 60 we can see that the commonly occuring prime factors are 2 and 3.

To calculate the prime factor, we multiply these numbers together:

GCF = 2 x 3 = 6
