The frequency table shows the results of a survey comparing weekly gasoline costs to the average number of miles a car can drive on a gallon of gasoline.

4-column table with 3 rows. First column has no label with entries less than 30 miles a gallon, greater than or equal to 30 miles a gallon, total. The second column is labeled less than 40 dollars a week with entries 33, 27, 60. The third column is labeled greater than or equal to 40 dollars a week with entries 77, 3, 80. The fourth column is labeled total with entries 110, 30, 140.

Marcel converts the frequency table to a conditional relative frequency table by row.

4-column table, 3 rows. First column no label with entries less than 30 miles a gallon, greater than or equal to 30 miles a gallon, total. Second column labeled less than 40 dollars a week with entries W, Y, almost equals 0.43. Third column labeled greater than or equal to 40 dollars a week with entries X, Z, almost equals 0.57.

Answer:

your profit is Double the price that you bought the kits

Step-by-step explanation:

x= cost of kit

you buy it x/2

x/2 + 4.5 .... (1)

x + x/2 +4.5 .... (2)

let x = 40

40/2 + 4.5 = 24.5

40 + 40/2 + 4.5 = 64.5

64.5 - 24.5 = 40

so

you buy it in x/2 = 40/2 = 20

and sell it in x = 40

40/20 = 2

your profit is Double the price that you bought the kits

The profit is Double the price that you bought the kits.

An equation is an expression that shows the relationship between two or more numbers and variables.

We have been given that the cost of the kits on sale for 50% of the original price, plus a shipping fee of $4.50 per kit.

Let x be the cost of kit.

Therefore,

x/2 + 4.5 .... (1)

x + x/2 +4.5 .... (2)

let x = 40

40/2 + 4.5 = 24.5

40 + 40/2 + 4.5 = 64.5

64.5 - 24.5 = 40

Therefore, buy it in x/2 = 40/2 = 20

and sell it in x = 40

40/20 = 2

Hence, the profit is Double the price that you bought the kits.

The total area of the room and the sitting room is 286.93 feet squared

The figure above is a composite figure as it has both rectangle and a semi circle.

The area of the figure(sitting room) is as follows:

total area = area of rectangle + area of semi circle

area of rectangle = lw

where

Therefore,

l = 15 ft

w = 14 ft

area of rectangle = 15 × 14 = 210 ft²

Area of semi circle = πr² / 2

Area of semi circle = 3.14 × 7² / 2

Area of semi circle = 3.14 × 49 / 2

Area of semi circle = 153.86 / 2

Area of semi circle = 76.93 ft²

Area of the sitting room and room= 210 + 76.93 = 286.93 ft²

Answer:  

=====================================================

Explanations:

Part (a)

In this case, the vertex is the highest point, so the vertex of function 1 is (-3, -1)

If the parabola was flipped so that it opened upward, instead of downward, then the vertex would be the lowest point.

----------------------------

Part (b)

We could graph this function to see where the highest or lowest point is, but there's another way we could find the vertex using algebra.

The given equation is in the form y = ax^2 + bx + c where in this case

The a and b values are plugged into the formula below to get

h = -b/(2a)

h = -16/(2*(-2))

h = -16/(-4)

h = 4

This is the x coordinate the vertex since the vertex is (h,k)

To find k, we plug that value of h into the original function to find its corresponding y value.

y = -2x^2 + 16x - 27

y = -2(4)^2 + 16(4) - 27

y = -2(16) + 16(4) - 27

y = -32 + 64 - 27

y = 5

We found that h = 4 leads to k = 5. The vertex is (h,k) = (4, 5)

----------------------------

Part (c)

We'll compare the y values of each vertex

The vertex with the larger y value is the winner, so that would be function 2. This parabola reaches a higher peak compared to the other curve.

The max value here is y = 5. In other words, it's the maximum output the function can produce.

If you graphed functions 1 and 2 together on the same xy grid (see below), you'll see that the curve for function 2 reaches a higher peak.

Answer:

2/4 cup

Step-by-step explanation:

Unsweetened cocoa powder needed = 3/4 cup

Unsweetened cocoa powder borrowed = 1/4 cup

how much of his own cocoa powder did he have?

Let

x = Unsweetened cocoa powder Mr kacanich has

Unsweetened cocoa powder needed = Unsweetened cocoa powder Mr kacanich has + Unsweetened cocoa powder borrowed

3/4 = x + 1/4

Subtract 1/4 from both sides

3/4 - 1/4 = x + 1/4 - 1/4

3/4 - 1/4 = x

x = (3-1)/4

x = 2/4 cup

The probability of not selecting a basketball from the bag is 18/19, or approximately 0.9474 (rounded to four decimal places).

Here, we have,

To find the probability of not selecting a basketball from the bag, we need to calculate the ratio of the number of items that are not basketballs to the total number of items in the bag.

Let's calculate it step by step:

Total number of items in the bag = 8 (tennis balls) + 2 (volleyballs) + 1 (basketball) + 3 (baseballs) + 5 (footballs) = 19.

Number of items that are not basketballs = 8 (tennis balls) + 2 (volleyballs) + 3 (baseballs) + 5 (footballs) = 18.

Therefore, the probability of not selecting a basketball is:

Number of items that are not basketballs / Total number of items in the bag = 18 / 19.

Hence, the probability of not selecting a basketball from the bag is 18/19, or approximately 0.9474 (rounded to four decimal places).
