"A construction company has a number of trucks designed to haul different amounts. The line plot displays the weight each truck can haul. If all the trucks are working at the same time, how many tons can the trucks carry?" I would also like a explanation too please

Answers

Answer 1

The line plot shows that the construction company has a number of trucks, each of which is designed to haul different amounts of weight.

If all of these trucks are working at the same time, we can calculate how many tons the trucks can carry in total. In order to do this, we need to look at the range of weight each truck is capable of carrying, and then add all of these numbers together.
In order to determine how many tons the trucks can carry, we need to use the information provided by the line plot. The line plot displays the weight each truck can haul, which is given in pounds. We need to convert the weight in pounds to tons in order to find the total weight that the trucks can carry.

To do this, we can use the following conversion factor:1 ton = 2000 poundsWe can use this conversion factor to convert the weight of each truck from pounds to tons. Once we have done this, we can add up the weights of all the trucks to find the total weight that the trucks can carry. Here are the steps:

Step 1: Convert the weight of each truck from pounds to tons Truck 1: 6,000 pounds ÷ 2,000 pounds/ton = 3 tons Truck 2: 9,000 pounds ÷ 2,000 pounds/ton = 4.5 tons Truck 3: 8,000 pounds ÷ 2,000 pounds/ton = 4 tons Truck 4: 10,000 pounds ÷ 2,000 pounds/ton = 5 tons Truck 5: 11,000 pounds ÷ 2,000 pounds/ton = 5.5 tons Truck 6: 9,500 pounds ÷ 2,000 pounds/ton = 4.75 tons

Step 2: Add up the weights of all the trucks3 + 4.5 + 4 + 5 + 5.5 + 4.75 = 26.75 tons. The trucks can carry 26.75 tons in total.

Question 7 Find the area of the region that is inside the rectangle and outside the circles (blue region ). The circles have a diameter of 3cm

Answers

The area of the blue region is 28.93 cm²

How to find the area of the blue region?

To find the area of the blue region, we need to subtract the area of the four circle from the area of the rectangle.

Since the diameter of the circle is 3cm. The radius (r) = 3/2 = 1.5 cm.

Length of the rectangle (L) = 4 * diameter of circle (we have 4 circles)

Length of the rectangle = 4 * 3 = 12 cm

Width of the rectangle (W) = diameter of circle = 3 cm

Area of rectangle = L * W

Area of rectangle = 12 * 3 = 36 cm²  

Area of circle = πr²

Area of circle = π * 1.5² = 2.25π cm²  

Area of the blue region = Area of rectangle - Area of circle

Area of the blue region = 36 - 2.25π

Area of the blue region = 36 - (2.25* 22/7)

Area of the blue region = 28.93 cm²

Given: ABCD pyramid All edges congruent AB = 4. 5 Find: V

Answers

The volume of the pyramid is found to be approximately 18.046 cubic units.

To find the volume (V) of the pyramid, we need to use the formula for the volume of a pyramid, which is V = (1/3) × Base Area × Height.

In this case, the base is a square, so we can find the area of the base by squaring one of the sides: Base Area = AB² = 4.5² = 20.25.

To find the height of the pyramid, we need to use the Pythagorean theorem to find the slant height, and then use that to find the height. Let h be the height of the pyramid and s be the slant height. We have:

s² = AB² + (1/2) DC² (Pythagorean theorem for triangle ABC)

s² = 4.5² + (1/2) DC²

Since all edges of the pyramid are congruent, we have DC = AB = 4.5. Substituting this into the equation above, we get:

s² = 4.5² + (1/2) × 4.5²

s² = 30.375

s ≈ 5.509

To find the height h, we can use the Pythagorean theorem again for triangle ABD:

h² = AB² - (1/4) s²

h² = 4.5² - (1/4) × 30.375

h² ≈ 7.875

h ≈ 2.807

Now that we have found the base area and the height, we can use the formula for the volume of a pyramid to find V:

V = (1/3) × Base Area × Height

V = (1/3) × 20.25 × 2.807

V ≈ 18.046

Therefore, the volume of the pyramid is approximately 18.046 cubic units.

Find the median of first 15 odd numbers 

Answers

Answer:

15

Step-by-step explanation:

The first 15 odd numbers are: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29

The formula to find the median of a set of numbers is:

Median = [(n + 1) / 2]th term

where n is the total number of terms in the set.

In this case, we have 15 terms in the set of the first 15 odd numbers. So, substituting n = 15 in the formula, we get:

Median = [(15 + 1) / 2]th term

Median = 8th term

To find the 8th term, we can simply list the first 15 odd numbers in ascending order and count 8 numbers from the beginning of the list. The 8th term is 15.

Therefore, using the formula, we get:

Median = 8th term = 15.

So, the median of the first 15 odd numbers is 15.

you sold 6 student tickets and 2 guest tickets for a total
of $105. What is the price of each ticket?

Answers

The price of each student ticket is $12.50 and the price of each guest ticket is $15.

What is substitution method?

The substitution method is a technique in algebra for solving systems of equations, which involves solving one equation for one variable, and then substituting that expression into the other equation.

According to question:

Let's start by assigning variables to represent the unknown prices of the student and guest tickets.

Let:

x be the price of a student ticket

y be the price of a guest ticket

Using this information, we can set up two equations based on the given information:

Equation 1: 10x + 5y = 200 (from the first day's sales)

Equation 2: 6x + 2y = 105 (from the second day's sales)

Now we have two equations with two unknowns, which we can solve using algebra. To do this, we can use a method called substitution, which involves solving one equation for one variable, and then substituting that expression into the other equation. Here's how to do it:

Solve Equation 1 for y:

10x + 5y = 200

5y = 200 - 10x

y = (200 - 10x)/5

y = 40 - 2x

Substitute y into Equation 2:

6x + 2y = 105

6x + 2(40 - 2x) = 105

6x + 80 - 4x = 105

2x = 25

x = 12.50

So the price of a student ticket is $12.50.

To find the price of a guest ticket, we can substitute x = 12.50 into Equation 1:

10x + 5y = 200

10(12.50) + 5y = 200

125 + 5y = 200

5y = 75

y = 15

So the price of a guest ticket is $15.

Therefore, the price of each student ticket is $12.50 and the price of each guest ticket is $15.

To find the distance between two points on a number line or in a coordinate plane, we use the distance formula. The distance formula is given by:

d = √((x2 - x1)² + (y2 - y1)²)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

None of the options provided represents the distance formula in its entirety. However, we can use option B as the first part of the distance formula, since it represents the absolute value of the difference between the x-coordinates of the two points:

Answers

The given statement "B ∩ C = C ∩ B" is true, since the intersection of two sets is a commutative operation, which means the order in which we list the sets does not matter.

To find the intersection of two sets, we need to identify the elements that are common to both sets. In this case, we can list the elements of each set and identify their common elements:

B = {a, b, c}

C = {a, c, e, g}

B ∩ C = {a, c}

C ∩ B = {a, c}

As we can see, the intersection of B and C is {a, c}, and the intersection of C and B is also {a, c}. The order in which we list the sets does not affect the result of the intersection operation, since the elements of both sets are the same.

Therefore, we can conclude that B ∩ C = C ∩ B is true, and that the intersection of B and C contains the same elements regardless of the order in which we list the sets.

In summary, the intersection of two sets is a commutative operation, which means that the order in which we list the sets does not affect the result. Therefore, B ∩ C = C ∩ B is true, and the intersection of B and C contains the same elements regardless of the order in which we list the sets.

The value of one currency represented in terms of another is called an exchange rate. It is the cost associated with exchanging one currency for another. The dynamics of supply and demand in the market dictate exchange rates, which are continually changing in response to a variety of political and economic variables including inflation, interest rates, trade balances, and geopolitical events. Currency rates have an impact on the price and profitability of transactions between nations, making them crucial for international commerce and investment. As they govern how much foreign currency can be received for a certain quantity of local currency, they are especially crucial for those who travel or transfer money overseas.

Given that, the exchange rate was £1 = $2.1.

Answers

B has a savings account, into which he must deposit $40 each month.

What's the point of the example?

Interest is frequently calculated as an annual percentage of the amount borrowed. This percentage represents the loan's interest rate. For instance, a bank will pay interest if you deposit money in a high-yield savings account.

From the time he was 11 to the time he was 18, Luke's parents saved for him for 8 years, or 8 years x 12 months every year, or 96 months.

Since they were saving $125 per month throughout this time, Luke had amassed the following sum:

$125/month x 96 months = $12,000

Luke must still pay the following expenses because he needs $12,480 for his first year of technological school:

$12,480 - $12,000 = $480

If he has one year left to save this amount, he will need to save:

Based on past experience, a bank believes that 8% of the people who receive loans will not make payments on time. The bank has recently approved 200 loans.(1) (7 points) What's the probability that over 10% of these clients will not make timely payments?(2) (11 pouts) 45% of the timely payments will not be made by under how many percentages of clients?

Answers

Thus, 45% of timely payments will not be made by under 100 - (165/200)*100% = 17.5% of clients.

what is binomial distribution?

The binomial distribution is a probability distribution that describes the number of successes in a fixed number of independent trials, where each trial can result in either a success or a failure.

The distribution is characterized by two parameters: the number of trials n and the probability of success in each trial p. The probability of exactly k successes in n trials can be calculated using the binomial probability formula:

P(X=k) = (n choose k) * p^k * (1-p)^(n-k)

(1) To find the probability that over 10% of the clients will not make timely payments, we need to use the binomial distribution. Let X be the number of clients out of 200 who do not make timely payments. Then X has a binomial distribution with parameters n = 200 and p = 0.08. We want to find P(X > 0.1*200) = P(X > 20).

Using the normal approximation to the binomial distribution, we can approximate X with a normal distribution with mean μ = np = 2000.08 = 16 and standard deviation σ = sqrt(np(1-p)) = sqrt(2000.08*0.92) = 3.36.

P(X > 20) can be approximated as P(Z > (20 - 16)/3.36) = P(Z > 1.19), where Z is a standard normal variable. Using a standard normal table or a calculator, we can find that P(Z > 1.19) = 0.1179.

Therefore, the probability that over 10% of the clients will not make timely payments is approximately 0.1179.

(2) Let Y be the number of clients out of 200 who make timely payments. Then Y has a binomial distribution with parameters n = 200 and p = 0.92 (since 8% of clients do not make timely payments, 92% do). We want to find the smallest k such that P(Y < k) > 0.45.

We can use a table of the cumulative binomial distribution or a calculator to find that P(Y < 164) = 0.4443 and P(Y < 165) = 0.4658. Therefore, the smallest k such that P(Y < k) > 0.45 is 165.

Thus, 45% of timely payments will not be made by under 100 - (165/200)*100% = 17.5% of clients.

The probability that over 10% of these clients will not make timely payments is approximately 0.03.

What exactly is probability?

Probability is a branch of mathematics that deals with the measurement and analysis of uncertainty. It is used to quantify the likelihood or chance of an event occurring, and is expressed as a number between 0 and 1, with 0 indicating an impossible event and 1 indicating a certain event.

Now,

(1) Let X be the number of clients who will not make timely payments out of 200 loans approved. We are given that the probability of not making timely payments is 8%, or 0.08. Since X follows a binomial distribution with n = 200 and p = 0.08, we can use the normal approximation to the binomial distribution to find the probability that over 10% of these clients will not make timely payments:

First, we need to calculate the mean and standard deviation of X:

mean = n * p = 200 * 0.08 = 16

standard deviation = sqrt(n * p * (1 - p)) = sqrt(200 * 0.08 * 0.92) = 3.19

Now we can use the normal distribution with a continuity correction to find the probability:

P(X > 0.1 * 200) = P(X > 20) = P((X - mean) / standard deviation > (20 - mean) / standard deviation)

= P(Z > 1.88) ≈ 0.03

Therefore, the probability that over 10% of these clients will not make timely payments is approximately 0.03.

(2) Let Y be the number of clients who make timely payments out of 200 loans approved. We are given that 45% of the timely payments will not be made, so the probability of making a timely payment is 1 - 0.45 = 0.55. Since Y also follows a binomial distribution with n = 200 and p = 0.55, we need to find the largest value of k such that the probability of at least k clients making timely payments is at least 0.45.

We can use a cumulative binomial distribution to find the probability:

P(Y ≥ k) = 1 - P(Y < k) = 1 - binom.dist(k - 1, n, p, TRUE)

We can then use trial and error to find the largest value of k such that P(Y ≥ k) ≥ 0.45:

P(Y ≥ 127) ≈ 0.455 > 0.45

P(Y ≥ 128) ≈ 0.426 < 0.45

Therefore, the largest value of k such that the probability of at least k clients making timely payments is at least 0.45 is 127. This means that under 63.5% of clients (127/200) will make timely payments.

The statement that is true regarding the graphed functions is that: B. f(-2) = g(-2).

What is the point-slope form?

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

m represents the slope.x and y are the points.

At point (2, 0), an equation of the line f(x) can be calculated by using the point-slope form:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 0 = (-4 - 0)/(-2 - 2)(x - 2)

y = -x + 2

For line g(x), we have:

y - 4 = (-2 - 4)/(0 + 2)(x + 2)

y = -3(x + 2) + 4

y = -3x - 2

When x = 0, we have:

g(0) = 0 + 2 = 2

f(0) = 0 - 2 = -2.

When x = -2, we have:

g(-2) = -(-2) + 2 = 4

f(-2) = -3(-2) - 2 = 4.

He discussed his findings with the inventory manager who indicated that the sales of the Hayden 2020 GS have been falling since 2020, and none had been sold in 2022, because a newer console, the Hayden 2022 GZ was released in January 2022.Jay researched this issue further and found that the Hayden 2022 GZ has the same applications as the older model, but has more processing power, better graphics, and a lower cost than the 2020 model.Jay emailed this information to Charles Sheen, the Chief Financial Officer, and recommended that the company apply the lower-of-cost-or-market method to the Hayden 2020 GS game consoles in inventory.Later that day, Charles emailed Jay and told him NOT to apply the lower-of-cost-or-market valuation to the Hayden 2020 GS inventory because "the company is under considerable pressure to maintain its track record of earnings growth, and a lower-of-cost-or-market adjustment would result in a significant decline in earnings this quarter."Because Charles was Jay's boss, he followed his instructions.In reviewing this case, answer the following questions (in complete sentences, explaining your answers):a) Who could be harmed by this decision?
