Based on the graph, estimate (to one decimal place) the average rate of change f

Answer:

  the cost function is defined as a step function

Step-by-step explanation:

You want to know why a cost graph has steps.

In the US, current first class postage rates for appropriately sized envelopes are 60¢ for the first ounce, and 24¢ for each additional ounce.

Envelopes below a certain weight cannot be mailed, and above that minimum (up to at most one ounce), the cost will be 60¢. That is, the first step is at cost=60¢, and extends from some minimum weight up to 1 ounce at that cost.

Above one ounce -- even very slightly above, the cost is 84¢. There is no weight where the cost is 61¢ or 62¢ or any other number between 60¢ and 84¢.

For the purpose of determining cost, the weight is rounded up to the next higher ounce. This guarantees that cost values will be a discrete set of values.

The weight can take on any real value. This is reflected in the continuous horizontal line at each level of cost.

The hollow circle at 1 ounce on the second step means that the cost for one ounce is not the value of that second step. The filled circle indicates the cost for one ounce is the value of the first step. The hollow circle also indicates that weights arbitrarily close to 1 ounce, but greater, will cost the same as for 2 ounces.

Additional comment

The minimum weight envelope that can be mailed first class will be a function of its size. Outside a certain size and weight range, the envelope will not be "machinable," so will incur an extra charge.

Answer:

120

Step-by-step explanation:

consider
1st angle= a
2nd angle = b
3rd angle = c

now,
b=5a ............. equation 1
c = a+12 ........ equation 2

as we know in a triangle, sum of all angle is 180.

so
a+b+c = 180
=> a +5a + (a+12 ) = 180
=> 7a = 180-12 =168
=> a = 168/7 = 24

so a= 24
b = 5(24) = 120
c = a+12 = 24+12 =36

so b = largest = 120

The point of intersection of the given two lines y = 4x - 1 and y = -2x + 5  is (1, 3).

According to the given question.

We have two equations

y = 4x - 1 ..(i)

and

y = -2x + 5 ..(ii)

As we know that, the point at which two lines intersect is called point of intersection.

Therefore, the point of intersection for the two lines y = 4x - 1 and y = -2x + 5  is given by

Subtracting equation ii from i

y - y = 4x - 1 + 2x -5

⇒ 0 = 6x - 6

⇒ 6x = 6

⇒ x = 1

Substitute the value of x in (i).

y = 4 - 1 = 3

Hence, the point of intersection of the given two lines y = 4x - 1 and y = -2x + 5  is (1, 3).

Improper fraction - 7/6

Step-by-step explanation:

The goal of the question is to get you to add the 2 distances the beetle crawled together.

First you have to give the fractions the same denominator.

5/6 & 2/6 (to change 1/3 to 2/6 multiply the top and bottom by 2)

Then you simply add the numerators.

The volume of aggregate that she needs to build the patio is 13.18 ft^3

We know that the backyard is 14ft long, 6 feet wide and 4 inches deep.

Rememeber that:

1ft = 12 in

Then:

4 in = (4/12) ft = (1/3) ft

Then the volume of the backyard is:

V = (14ft)*(6ft)*(1/3 ft) = 28ft^3

Now we know that we have a mix of 4 parts aggregate to 4.5 parts loose cement that need to fill these 28 cubic feet.

Note that:

4 + 4.5 = 8.5

How many times we have 8.5 in 28?

28/8.5 = 3.294

Now for each of these we have 4 parts of aggregate, then the volume of aggregate that we need is:

4*3.294 ft^3 = 13.18 ft^3

C. 12/1 > 1 is the inequality which is true as 12/1 is 12 and 12 is obviously greater than 1.

Inequality, A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to. Inequality issues can be expressed as either questions or theorems, and both can be resolved using techniques that are similar to those used to resolve equations.

The triangle inequality, for instance, stipulates that the length of the remaining side of a triangle is more than or equal to the sum of the lengths of any two of its sides. Many of these inequalities are used in the proofs of mathematical analysis' most significant theorems.

The number of cockroaches in Chandler in the year 2025 will be 3237500 or 3.23 million approx

Approx number of cockroaches in the year 2020 in Chandler = 3500000 or 3.5 million

Percentage decrease in cockroaches every 12 years = 18%

Percentage decrease in cockroaches every year = 18/12 = 1.5%

So, in 5 years the percentage decrease in cockroaches will be = Percentage decrease every year*No. of years = 1.5*5 = 7.5%

The number of cockroaches in 2025 will be: 3500000 - 7.5% of 3500000

= 3500000 - 7.5/100*3500000

Answer:

34%

Step-by-step explanation:

In the sample of 300 voters, 102 said they would vote for brown. The sample statistic is just the percent given by the sample. Find the percent by dividing the voters who said they'd vote for brown by the entire sample group:

[tex]\frac{102}{300}=0.34[/tex]

Convert this to a percentage:

34%

the sample statistic for the percentage of voters surveyed who said they would vote for Brown is  34%.

we  start by divide the number of voters who said they will  vote for Brown by the total number of voters surveyed and then multiply by 100.

Number of voters surveyed (n) = 300

Number of voters who said they'd vote for Brown = 102

The Sample statistic for the percentage of voters who said they would vote for Brown:

Percentage of voters for Brown = (Number of voters for Brown / Number of voters surveyed) * 100

Percentage of voters for Brown = (102 / 300) * 100

x+y+z = 3064

(y-79) + (y) + (y+377) = 3064

3y + 298 = 3064

3y = 3064-298
