Please help! Looking for an explanation for how the problem is done, tysm :)

Answer:

8.48cm²

Step-by-step explanation:

area of a sector = [tex]\frac{0\pi r^2\\\\}{360}[/tex]

where 0 = angle measure of sector

and r = radius

we are given the angle measure ( 23° ) and the radius ( 6.5 cm )

so all we have to do is plug in the values into the formula

(Note that the question asks us to use 3.14 for pi)

[tex]A=\frac{23*3.14* 6.5^2\\\\}{360}\\6.5^2 = 45.25\\23*3.14 =72.22\\72.22*45.25 = 3051.295\\\frac{3051.295}{360} =8.47581944[/tex]

so the area of the sector = 8.47581944 cm^2

finally we want to round to the nearest hundredth and we get that the answer is 8.48cm²

Answer:

half of 11 is: 5.5

5.5 x 3.14 x 2 = 34.54

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.

Answer:

As long as I know if it's not the same then its not equal, because if you solve it they will give you different answers.

Answer:

y=7, -3, 3, -9, 1 (in the empty boxes from left to right)

Step-by-step explanation:

Since y=x-2, all you have to do is take an x value from the top box and subtract 2 from that number to find the value of y.

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

Answer:

Answer: 20,532

Step-by-step explanation:

17,400(.02)=348

348(9)=3132

17,400+3132=20,532

Answer:

Step-by-step explanation:

This is an exponential growth function of the form:

[tex]y=ab^x[/tex] where a is the initial population and b is the growth rate. This could also be written as

[tex]y=a(1+r)^x[/tex] which is a bit more accurate. We'll use that one. r is the percent growth: 2% for us.

Filling in the formula:

[tex]y=17400(1+.02)^x[/tex] and then simplifying:

[tex]y=17400(1.02)^x[/tex]

That's the model for this population. Filling in any number of years for x will give you the population y. Our time is 9 years:

[tex]y=17400(1.02)^9[/tex]

Take care of the exponents first, giving us:

[tex]y=17400(1.195092569)[/tex] and then multiply to get

y = 20,794.6 or 20,794 people (since you can't have 6/10 of a person)

Answer:

There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice

Answer [tex]m=250w[/tex]

Step-by-step explanation:

To write an engebraic expression, you should first start off by defining the variables.

Money earned = m

Weeks = w

Next, you have to define the relationship.

Shawn earns $250 per week, so in 2 weeks, he will earn 500, 3 weeks, 750, and so on. I did this by mulitplying, so amount of weeks times the amount of money earned would equal the total money he earned over "w" amount of weeks.

To create the expression, you just have to put the numbers and variables together.

m (money earned over "w" weeks) = 250 (money per week) w (number of weeks).

m=250w

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.

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:

option c is the correct answer

Answer:

y = (1/4)*x + 3

Step-by-step explanation:

A linear equation can be written as:

y = a*x + b

Where a is the slope, and b is the y-intercept.

If the line passes through the points (x₁, y₁) and (x₂, y₂) the slope can be written as:

a = (y₂ - y₁)/(x₂ - x₁)

In this case, we know that the line passes through the points (0, 3) and (8, 5)

Then the slope will be:

a = (5 - 3)/(8 - 0) = 2/8 = 1/4

Then this line is something like:

y = (1/4)*x + b

Now we want to find the value of b.

Here we can use one of the two points that we know, for example, I will use the point (0, 3), this means that when x = 0, we must have y = 3.

If we replace those two values in the line equation, we get:

3 = (1/4)*0 + b

3 = b

Then the equation for the line L is:

y = (1/4)*x + 3
