Answer:

A. 2, 3, and 4

B: 4

Step-by-step explanation:

Average mass is defined as, adding masses of all bodies and then divide by number of bodies.

(a). Kilograms, grams and milligrams

(b) Randomly pick 42 fish from the entire pond and weigh each of them.

(a). Since we are interested in the masses of the fish and not the time

so that, only unit of mass is to be considered.

Therefore,  Kilograms, grams and milligrams  are used to find the average mass.

(b). Since,  Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen

Therefore, Randomly pick 42 fish from the entire pond and measure their masses. This will provide a representative sample with no bias.

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:

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.

Step-by-step explanation:

Answer: 3(500+x)=1800

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

Solution Set:

(2,3)

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.

Step-by-step explanation:

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:

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 & 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.

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:

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:

B

Step-by-step explanation:

The distributive property states that:

a(b + c) = ab + ac

Look at the choices:

A: 39 + 9 = 45

There's nothing of this form; in fact, there aren't even any parentheses, so eliminate A.

C: 36 times 9 = 9 times 36

This is saying 36 * 9 = 9 * 36. Again, there aren't any parentheses. Actually, this demonstrates the commutative property.

D: (12 + 3)3 = 3(12 + 3)

There are parentheses, but they're on both sides, so this can't be right, either. In fact, this is the associative property.

By elimination, the answer is thus B.

The rule of distributive property states that [ a(b + c) = ab + ac ].

So, we need to find an answer choice that contains that specific format.

Option A is incorrect because there is nothing to solve for on the right side.

Option B is correct because it contains the same format as the rule stated above.

Option C is incorrect because its the same as [ 36 * 9 = 9 * 36 ] and it's not in the same format as the rule.

Although Option D has half of the format in the rule, it doesn't have the other half containing what it looks like after the distributive property is appplied. So, this is incorrect as well.

Therefore, the answer is B.

Best of Luck!
