Step-by-step explanation:

Answer:

a part of the population that represents the entire population

Step-by-step explanation:

A sample simply refers to a smaller group of observation usually drawn from a larger group or a collection of the total possible observation that fits a particular or specific characteristic(population). This smaller group or subset of observation is usually chosen to be representative of the larger group of population. Representative Samples are usually obtained by drawing at random from the population and are very important where using the entire population for a study seems impossible or very expensive or intensive.

Answer: 192 ft

Step-by-step explanation:

The area of the walkway will be 96 square feet.

Hence, The correct option is C.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Given that;

The dimensions of the crosswalk are,

19 feet

And, 5 feet

Hence, The area of the cross-walk will be calculated as below,

Area = Length x Width

Area = 19 x 5

Area = 96 square feet

Therefore, The area will be equal to 96 square feet.

Answer:  the third one

Step-by-step explanation:

Answer:

3/2

Step-by-step explanation:

y2 - y1/ x2 - x1

7 -(-5) / 6 - (-2)

12/ 8

3/2

Answer:

Step-by-step explanation:

y = 5

All sides measure the same So 8y= 40          y = 5

x = 30 degrees

The straight line of 40+40 is a straigth angle of 180 Each angle of equilateral triangle is 60 degrees.So its supplementary is  120.The other 2 angles need to add to 60 (30 each) to sum 180 in a triangle

Answer:

y=(8/3)x+3

Step-by-step explanation:

8x-3y=-9

-3y=-8x-9

y=(8/3)x+3

Answer:

x = 3

y = 11

Step-by-step explanation:

8x - 3y = -9

8(3) - 3(11) = -9

24 - 33 = -9

Step-by-step explanation:

[tex] \frac{35x - 2 - 93}{2} = 7x + 5[/tex]

[tex] \frac{35x - 95}{2 } = 7x + 5[/tex]

[tex]17.5x - 47.5 = 7x + 5[/tex]

[tex]17.5x = 7x + 52.5[/tex]

[tex]10.5x = 52.5[/tex]

[tex]x = 5[/tex]

Plug 5 in for 7x+5.

[tex]7(5) + 5 = 40[/tex]

Answer:

(17/25)^5 = 0.145393 = 14.539%

Step-by-step explanation:

78% = 78/100 or 17/25 simplified

probability of winning each game is 17/25

The probability that the Islanders will win at least five out of six games in a series against the Rangers is 0.4.

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

The probability that the Islanders will win the Rangers in a game = 78%      ⇒ [tex]0.78[/tex]

The probability that the Islanders will lost the Rangers in a game is

⇒ [tex]1-0.78=0.22[/tex]

The probability that the Islanders will win at least five out of six games in a series against the Rangers is

⇒ [tex]6C_{5} (0.78)^{5}(0.22)^{1}[/tex]

⇒ [tex](6)(0.2887)(0.22)[/tex]            [∵ [tex]6C_{5} =6[/tex]]

⇒ [tex]0.3811[/tex] ≈ [tex]0.4000[/tex]

Hence we can conclude that the probability that the Islanders will win at least five out of six games in a series against the Rangers is 0.4.

Answer:

-2

Step-by-step explanation:

The answer is -2

Explanation:

First of all we need to identify the problem.

Y= -X-4

We can tell already from this that the X is going to be negative.

If X=-2

Now we can change the problem to:

Y= -2-4

And can even change it to

-2-4

Well the way I learned it

A negative number minus a negative number is a negative number

A positive number minus a positive number is a positive number

Simple Right?

So what's a negative number minus a positive number?

Its a negative number!

So the answer is -6

Answer:

60,000 people

Step-by-step explanation:

Given the number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240,

x is the number of years after 2014

We can find the number of people that bought the cell phone in 2020. In year 2020, that will be after 6years

Substitute x = 6 into the expression

y=-30x+240

y=-30(6)+240,=

y = -180 + 240

y = 60

Since y is in thousands, hence the the number of people that have bought the cell phone by 2020 is 60,000 people

Answer:

36 inches of wood

Step-by-step explanation:

8+8+10+10= 36

Answer:

five or more than five

Step-by-step explanation:

From the chart, we know that,

Number of children who chose soccer = 7   (this was the highest)

Number of children who chose swimming = 3

So for swimming to be chosen the most, it should gave been chosen by more than 7 children, i.e. 8 children or more than 8.

So the difference between 8 children and 3 children is = 8 - 3

                                                                                            = 5

Thus, 5 is the least number of other children to chose swimming.

Therefore, Sam asked at least 5 number of children or more than 5.
