Answer:

I

Step-by-step explanation:

Answer:

I believe the slope is 1.

Step-by-step explanation:

using the points, (2,4) and (-5,-3), I tried to find out the difference in point if both x and y spots. Then I figured out that the space between -5 and 2( the x-coordinates) is 7, and the space between 4 and -3( the y-coordinates) is 7 as well. No I add these numbers into y/x which is 7/7 and that so happens to be equal to 1 as a whole number.

Answer:

9000 metres

Step-by-step explanation:

He went on a 54 km hike. First, we have to find this distance in metres.

1 km = 1000 m

54 km = 54 * 1000 = 54000 m

He divided the distance evenly over 6 days.

To find how many metres he walked each day, we divide the total distance he hiked by the number of days spent. That is:

54000 / 6 = 9000 metres

He walked 9000 metres each day.

Answer:

150 feet

Step-by-step explanation:

Assuming the deck is a rectangle, you need to multiply each side by 2 and add them together.

Answer:

50 yards

Step-by-step explanation:

Let l = length, w = width, and P = perimeter in feet. Let x equal perimeter in yards.

To solve this problem, we first need to find the perimeter of the deck.

To do so, use the formula 2l + 2w = P.

Since the deck is 49 feet long and 26 feet wide, plug in 49 for l and 26 for w.

2(49) + 2(26) = P

Evaluating 2*49 and 2*26, the equation becomes 98 + 52 = P.

Evaluating 98 + 52, the equation becomes 150 = P.

The next step in this problem is to convert feet to yards. We know that Robert needs 150 feet of lights. Since there are three feet in a yard, we can use the formula P = 3x to find the amount of yards of lights Robert needs.

Plugging in 150 for P, the equation becomes 150 = 3x.

Dividing both sides by 3, the equation becomes 50 = x.

Therefore, the final answer is 50 yards.

Answer:

$24,890.46, $25,109.59

Step-by-step explanation:

Given:

n = 48, the sample size

m = $25,000, th sample mean

σ = $3000, the maximum variance

The standard deviation is

s = √σ = √(3000) = 54.772

As a rule of thumb, the range is 4 times the standard deviation. Therefore the range is

R = 4*54.772 = 219.09

Half the range is

R/2 = 219.09/2 = 109.45

The required  range is

(25000-109.45, 25000+109.45) = (24890.46, 25109.54)

Answer: $24,890.46, $25,109.54

Answer:

Some probability situations involve more than one event. When the events do not affect one another, they are known as independent events. Independent events can include repeating an action like rolling a die more than once, or using two different random elements, such as flipping a coin and spinning a spinner. Many other situations can involve independent events as well. In order to calculate probabilities accurately, we need to know if one event influences the outcome of other events.

Answer:

The outcome of the first roll does not affect the probabilities of the outcomes for the second roll. Therefore, these events are independent.

Step-by-Step Explanation:

The events are independent since the person rolling had rolled a number cube twice, not switching it for the two events.

Answer:

Domain: All real numbers, Range: All real numbers greater or equal to 0.

Step-by-step explanation:

A second order polynomial is a continuous function and therefore, domains is the set of all real numbers. Lastly, the range of the function according to the graph is all values of x greater or equal to 0. The positive leading coefficient of the polynomial indicates the existence of an absolute minimum.

The graph of function is attached below.

Domain of function is, (-∞ ,∞ )

Range of function is (-∞, 0)

The domain of function is defined as all input values to a function, for which function is defined.

Range of the function is output values to a particular input value.

Step-by-step explanation:

Proportional means that it will have a constant rate of change.  If we divide 4/0.8 in the first example, we get 5.  In the second example, we need to find x/3.2=5.  16/3.2=5.  In the third example, we need to find 2 numbers divided by each other that equals 5.  64/12.8=5

a) [tex]\hat p =\frac{Upper+Lower}{2}= \frac{0.47+0.63}{2}= 0.55[/tex]

b) [tex] ME = \frac{Upper-Lower}{2}= \frac{0.63-0.47}{2}= 0.08[/tex]

c) For this case in order to find the number of people who would support the bike lanes we just need to multiply the estimated proportion by the total size and we got:

[tex] X = 0.55* 75783= 41680.65 \approx 41681[/tex]

Step-by-step explanation:

For this case we have an interval for the true proportion of adults in a certain town who want to add bike lanes to a major roadway:

[tex] 0.47 \leq p \leq 0.63[/tex]

Part a

For this case the point of estimate is given by:

[tex]\hat p =\frac{Upper+Lower}{2}= \frac{0.47+0.63}{2}= 0.55[/tex]

Part b

We can estimate the margin of error with this formula:

[tex] ME = \frac{Upper-Lower}{2}= \frac{0.63-0.47}{2}= 0.08[/tex]

Part c

For this case in order to find the number of people who would support the bike lanes we just need to multiply the estimated proportion by the total size and we got:

[tex] X = 0.55* 75783= 41680.65 \approx 41681[/tex]

Answer:

78

Step-by-step explanation:

The median of a set is the middle number.

First, we have to put the numbers into numerical order.

42, 55, 69, 74, 78, 83, 83, 97, 99

Then, count the number of numbers, which is 9

Then, the middle of 9 is 5, because:

1, 2, 3, 4, 5, 6, 7, 8, 9

There are four numbers on either side of 5.

Lastly, find the 5th number in the set.

It is 78. So, the median of the set is 78.

Answer:

78

Step-by-step explanation:

to know the median you should first order the numbers from the smallest to the largest. that is

42,55,69,74,78,83,83,97,99

you take the number in the middle or if the number found in the middle are 2 then you add them up and divide them by 2 because they are 2. so in this case the number is only one which is 78 so that is the median.

Answer:

a₁₁ = -3/2

Step-by-step explanation:

                       3.5; 3 ; 2.5; 2 ; 1.5..............aₙ

                            aₙ = -n/2  +  4

         a₁₁ = (-0.5)(11) + 4

         a₁₁ = -3/2

numbers 3x + 2y = 12

y = x + 1

Substitution Method

Since y is already isolated in the second equation we can use that value, to substitute for y in the first equation.

3x + 2 (x + 1) = 12

3x + 2x + 2 = 12

5x = 12 − 2

5x = 10

x = 2

Substitute the computed value of x to the second equation to determine the value of y.

y = 2 + 1

y = 3

Elimination Method

3x + 2y = 12

x − y = −1

Multiply the second equation by 2 to eliminate

x or you can also multiply the second equation by 3 to eliminate y. However since it is easier to multiply by 2, I will follow the first method.

3x + 2y = 12

2x − 2y = −2

Adding the two equations eliminates the y variable.

5x = 10

x = 2

Substitute the computed value of x to the second equation to determine the value of y.

y = 2 + 1

y = 3

Answer & Step-by-step explanation:

For this problem, we will use the distance formula.

[tex]d=\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

For our (x1, y1), we will use (-3, 1). For our (x2, y2), we will use (1, 5). Now let's plug in our numbers and solve the problem.

[tex]d=\sqrt{(1-(-3))^2+(5-1)^2}[/tex]

[tex]d=\sqrt{4^2+4^2}[/tex]

[tex]d=\sqrt{16 + 16}[/tex]

[tex]d=\sqrt{32}[/tex]

[tex]d=5.657[/tex]

So, the distance between (-3,1) and (1,5) is 5.657 units.
