Step-by-step explanation:

2850/78 = 36.538

Answer:

36.538

Step-by-step explanation:

since he has 2,850 worth of string and he needs 78 pieces, you would divide 2,850 by 78 which gives you 36.53846154 but you would make it 36.538. if you needed to round by the tenths, its 36.5, hundredths is 36.54, and thousandths is 36.538.

Answer:

Ham Sandwich with American cheese = 0.015

PB and J without cheese = 0.1575

Both probabilities together = 0.1725

Step-by-step explanation:

Attached is the tree diagram

Hope this helped

Answer:

The probability that you would choose to make a ham sandwich with American cheese OR a PB and J sandwich without cheese is 35.25%.

Step-by-step explanation:

Tree diagrams show the probabilities for a sequence of two or more independent events.

For the given problem:

These events are independent events since each event is not affected by the previous event.

The given probabilities for each choice are:

Create a tree diagram with the given information (see attachment 1).

The end of each branch should be labelled with its outcome, and the probability of that event should be written along the branch.

To calculate the probability of each combination, multiply the probabilities along the branches.

To find the probability that you would choose to make a sandwich with white bread, ham and cheese, multiply along the branches representing those events:

⇒ 50% × 30% × 65% = 9.75%

To find the probability that you would choose to make a sandwich with wheat bread, ham and cheese, multiply along the branches representing those events:

⇒ 50% × 30% × 65% = 9.75%

To find the probability that you would choose to make a sandwich with white bread, PB & J and no cheese, multiply along the branches representing those events:

⇒ 50% × 45% × 35% = 7.875%

To find the probability that you would choose to make a sandwich with wheat bread, PB & J and no cheese, multiply along the branches representing those events:

⇒ 50% × 45% × 35% = 7.875%

On a tree diagram, when moving along the branches (from left to right) we multiply, and when moving down we add.

Therefore, to calculate the probability that you would choose to make a ham sandwich with American cheese, or a PB and J sandwich without cheese, add the four found probabilities:

⇒ 9.75% + 9.75% + 7.875% + 7.875% = 35.25%

Answer:

The correct answer is C = 16 兀

explanation:

In this problem, C represents the cost and r represents the rate. The formula for calculating the cost is C = 2 * r, where C is the cost in 兀 and r is the rate in 兀/unit.

When r is 8 兀/unit, the cost is C = 2 * 8 = 16 兀.

Answer:

C = 16 π

Step-by-step explanation:

If C = 2 π r, and r = 8:

C = 2 π (8)

Simplify (multiply 2x8):

C = 16 π

Answer:

1/4

Step-by-step explanation:

you add 3/5 to the other side and find the lcm making it 6/10--1/10=5/10. Then 5/10 divided by 2 = 2.5/10 which you can simplify to 1/4.

Answer: x=1/4

Step-by-step explanation:

1. Isolate x: if you move -3/5 to the other side, your equation would become

=> 2x=-1/10+3/5

2. Find the common denominator: since you can't add -1/10 with 3/5 without simplifying, you're equation would change to this:

=> 2x=-1/10+6/10

3. Simplify:

=> 2x=5/10  =>  2x=1/2

4. Divide:

=> 2x=1/2  =>  x=1/2*1/2  =>  x=1/4

The probability that a red card is drawn at least once by the third draw is 0.88.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Let, a card is drawn from a standard deck of 52 cards and then placed back into the deck.

In a standard 52 card deck the red cards are 26.

So,

P(red) =  n(red cards) / n(total cards)

          = 26 / 52

P(red) = 0.50

Now, X ≈ Bin (n = 3, P = 0.50)

P(X = x) = (n  x) p^x (1 - p)^n-x

(n  x) = \(\frac{n!}{x!(n-x)!}\)

P(X ≥ 1) = 1 - P(X < 1)

            = 1 - P(X = 0)

            = 1- (3  0)(0.5)^0(0.5)^3

            = 1 - 0.125

             = 0.875

P(X ≥ 1)  = 0.88

Hence, the probability that a red card is drawn at least once by the third draw is 0.88.

Answer:

A. Square

Step-by-step explanation:

Hmm yes looks very much like a square if you ask me. This is right!!

The statement, For every point on the graph of f(x), there is a point on the graph of F⁻¹(x) with reversed coordinates is false.

In relation to the original function f, the inverse function is denoted by the symbol f⁻¹, and both the original function's domain and its range are transformed into the inverse function's domain and range, respectively. Swapping (x, y) with (y, x) with reference to the line y = x yields the graph of the inverse function.

We know that inverse of function is NOT the reciprocal of f. The composition of the function f and the reciprocal function f inverse gives the domain value of x.

Hence, the statement, For every point on the graph of f(x), there is a point on the graph of F⁻¹(x) with reversed coordinates is false.

The first is the correct option.

An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.

y = a(1+r)ˣ,

where a is the initial population and r is the rate in decimals and x is the time period.

Given:

The population of a bacterial culture grows at a rate of 4.5% every hour.

If there were 200 bacteria at the start,

then the number of bacteria after 10 hours are,

Step-by-step explanation:

Predict:

Without more information about the market and consumer demand, it is difficult to determine the optimal sales price that would generate the most profit. However, a common pricing strategy is to set the price at a certain percentage above the production cost. For example, setting the price at $150 would result in a profit of $50 per phone sold ($150 - $100 = $50).

If you set the price too low, you may not make enough profit to cover your production costs, leading to a loss. Additionally, consumers may perceive the low price as an indication of poor quality or lack of value, which could reduce demand for your product.

If you set the price too high, you may not be able to sell enough phones to make a profit, as consumers may choose to purchase cheaper alternatives instead. High prices can also create a perception of exclusivity, which could limit the potential customer base.

Calculate:

See the table below.

Price ($) Quantity Demanded (Q) Total Revenue (TR) Total Cost (TC) Profit (TR-TC)

100 20 2,000 2,000 0

120 18 2,160 1,800 360

140 16 2,240 1,600 640

160 14 2,240 1,400 840

180 12 2,160 1,200 960

200 10 2,000 1,000 1,000

Analyze:

Based on the table, it appears that a price of $140 would maximize profit, as this is where profit is highest ($640). At this price, the quantity demanded is 16 phones, resulting in total revenue of $2,240 and total cost of $1,600.

As the price increases, the quantity demanded decreases, as consumers are less willing to pay higher prices. This leads to lower total revenue and profit.

The x-intercept is when profit is equal to zero, or where TR = TC. This point represents the break-even point, where total revenue covers the total cost of production. In this case, the x-intercept is at a price of $150.

Quadratic Regression:

a) Using the provided calculator link, we obtain the following values:

a = 0.05

b = -10

c = 500

r2 = 0.9

b) The standard form of the equation that represents the data is:

f(x) = 0.05x2 - 10x + 500

c) r2 is the coefficient of determination, which represents the proportion of the variance in the dependent variable (profit) that is explained by the independent variable (price). An r2 value of 0.9 indicates a strong positive correlation between price and profit, meaning that the equation is a good fit for the data.

d) See graph below.

Graph of quadratic equation

Evaluate:

Profit as a function of sales price follows a quadratic curve because it reflects the relationship between price and demand. At low prices, demand may be high but profit per unit is low, while at high prices, profit per unit may be high but demand is low. The optimal price is the one that balances these
