Answer:

\(5820\) square inches

Step-by-step explanation:

For the rectangular prism in the middle:

\(24*30=720*2=1140\)

\(10*30=300*2=600\)

\(1140+600=1740\)

For the left triangular prism:

\(10*24=240\)

\(26*30=780\)

\(24*30=720\)

\(10*30=300\)

\(240+780+720+300=2040\)

For the other right triangular prism, it's the same.

Let's add now to find the surface for the whole ramp.

\(1740+2040+2040=5820\)

Hope this is helpful to you

log 72 to the base 2n is equal to log 18 to the base n if n is equal to \(2^{1/10}\).

We can use the change-of-base formula to convert both logarithms to a common base, such as base 10:

log 72 / log 2n = log 18 / log n

We can simplify log 72 as follows:

\(log 72 = log (2^3 * 3^2) = 3 log 2 + 2 log 3\)

Similarly, we can simplify log 18 as:

\(log 18 = log (2 * 3^2) = log 2 + 2 log 3\)

Substituting these expressions into the original equation, we get:

(3 log 2 + 2 log 3) / log 2n = (log 2 + 2 log 3) / log n

Multiplying both sides by log n * log 2n, we get:

(3 log 2 + 2 log 3) log n = (log 2 + 2 log 3) log 2n

Expanding the logarithms using the power rule, we get:

\(3 log (n^3) + 2 log (n^2) = log (2n) + 2 log (n^3)\)

Simplifying and rearranging terms, we get:

\(3 log (n^3) - 2 log (n^3) = log (2n) - 2 log (n^2)\)

\(log (n^9) = log (2n / n^2)\)

\(log (n^9) = log (2/n)\)

Taking the exponential of both sides, we get:

\(n^9 = 2/n\)

Multiplying both sides by n, we get:

n^10 = 2

Taking the 10th root of both sides, we get:

\(n = 2^{1/10}\)

Therefore, log 72 to the base 2n is equal to log 18 to the base n if n is equal to \(2^{1/10}\)

Step-by-step explanation:

Answer:

A.) -3.396

Step-by-step explanation:

On edg ;)

The order from least to greatest is:

⇒ 3/2, 117/1.

To compare fractions, we want to make sure they all have the same denominator.

117 is already a whole number, so we can write it as a fraction with a denominator of 1:

⇒ 117/1.

For the mixed number 2'2'2, we can convert it to an improper fraction by multiplying the whole number (2) by the denominator (2) and adding the numerator (2), then placing that result over the denominator:

2'2'2 = (2 x 2) + 2 / 2

         = 6/2

         = 3

So now we have:

117/1, 3/2

We can see that 117/1 is the larger fraction because it is a whole number, and 3/2 is the smaller fraction.

So, the order from least to greatest is:

⇒ 3/2, 117/1.

The procedure for revising probabilities based on additional information is referred to as Bayesian updating

The procedure for revising probabilities based on additional information is referred to as Bayesian updating. Bayesian updating is a fundamental concept in Bayesian statistics, which allows for the incorporation of new evidence or data to update and refine prior beliefs or probabilities.

In Bayesian updating, the process begins with an initial prior probability, which represents the initial belief or knowledge about an event or hypothesis before any evidence is observed. As new evidence or data becomes available, it is used to update the prior probability and generate a posterior probability. The posterior probability represents the revised belief or probability after incorporating the new information.

Bayesian updating follows the principles of Bayes' theorem, which mathematically describes the relationship between prior probabilities, likelihoods, and posterior probabilities. It involves combining the prior probability with the likelihood of observing the data given the hypothesis and then normalizing the result to obtain the posterior probability.

The beauty of Bayesian updating is that it allows for a flexible and iterative process of continuously updating beliefs and probabilities as new information emerges. It provides a framework for incorporating both subjective prior beliefs and objective data to make more informed decisions and predictions. Bayesian updating has applications in various fields, including machine learning, decision-making, and scientific research.

The closest solution to this total among the available possibilities is 0.68, indicating that the portfolio is likely to surpass its benchmark in three or fewer quarters over the course of a year.

The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms.

Here,

The probability that the portfolio outperforms its benchmark in three or fewer quarters over the course of a year is the sum of the probabilities of outperforming the benchmark in exactly 0 quarters, 1 quarter, 2 quarters, and 3 quarters.

Since the probability of outperforming the benchmark in any quarter is 0.75, the probability of not outperforming the benchmark in a quarter is 1 - 0.75 = 0.25.

The probability of not outperforming the benchmark in exactly 0 quarters is 0.25⁰ = 1

The probability of not outperforming the benchmark in exactly 1 quarter is 0.25¹= 0.25

The probability of not outperforming the benchmark in exactly 2 quarters is 0.25² = 0.0625

The probability of not outperforming the benchmark in exactly 3 quarters is 0.25³ = 0.015625

So, the probability of outperforming the benchmark in exactly 0 quarters, 1 quarter, 2 quarters, and 3 quarters is 1 - 0.25⁰, 1 - 0.25¹, 1 - 0.25², and 1 - 0.25³, respectively.

The sum of these probabilities is the probability of outperforming the benchmark in three or fewer quarters over the course of a year:

P(outperform in three or fewer quarters) = 1 - 0.25⁰ + 1 - 0.25¹ + 1 - 0.25² + 1 - 0.25³

This expression can be calculated to get an exact answer, but to get the closest answer to the options given, we can round off the intermediate results to 2 decimal places:

P(outperform in three or fewer quarters) = 1 + 0.75 + 0.94 + 0.98

The closest answer to this sum among the options given is 0.68, so the probability that the portfolio outperforms its benchmark in three or fewer quarters over the course of a year is closest to 0.68.

After 2.94 Hr. or approximately 3 Hr. both cars will be 250 miles apart.

We have,

The value of the speed of the car moving in the north direction =35 mph

The value of the speed of the car moving in the south direction=50 mph

From above, we can conclude that both are going in the opposite direction

So, the value of the net speed/ relative speed of both the car will be =35+50=85 mph

As we know,

The value of distance can be determined by using the relationship:

Distance = speed * time

So, for determining the value of time, we will put the value of total distance covered and the value of relative speed in the above expression.

Thus, we will get it as:

250=85*t

So, the value of the time taken = t=250/85=2.94 hours approx 3 hours

To determine the optimal order quantity for Rocky Mountain Tire Center, you must consider ordering costs, storage costs, and the purchase price of the tires. The order quantity should minimize the total cost including both ordering cost and storage cost.

The EOQ formula is given by: EOQ = √((2DS) / H)

Where: D = Annual demand (7,000 go-cart tires)

S = Ordering cost per order ($40) H = Holding cost - percentage of the purchase price (40% of the purchase price)

we need to determine the purchase price per tire based on the quantity ordered.

EOQ = √((2 * 7,000 * 40) / (0.4 * 15))

=118 tires

they should order approximately 118 tires.

Yolanda is shopping for a used car in a city where the sales tax is 10% and the title and license fee is \($300\). If the maximum that she can spend is \($8000\), then she should look at cars in a price range of more than \($6,970.70\).

Solution:

The cost of the title and license fee is $300.The sales tax is 10%.This means that she must leave 10% of the price for sales tax.Therefore, the equation for the total amount that Yolanda should spend on a car can be written as:

\($8000 = x + 0.10x + $300\)

where x is the original cost of the car before taxes and fees.

$8000 = 1.10x + $300Solve for x:

Subtract $300 from both sides:

\($8000 - $300\)

= 1.10xDivide both sides by 1.10:

\($7,700 = x\)

Therefore, she should look at cars that cost more than \($6,970.70 ($7,700 + 10% tax = $8,470.00 + $300\) fees

= \($8,770.00)\).

Step-by-step explanation:

To determine whether the ice cream scoop will fit in the cone or overflow, we need to compare the volume of the scoop to the volume of the cone. If the volume of the scoop is less than or equal to the volume of the cone, the scoop will fit in the cone. If the volume of the scoop is greater than the volume of the cone, the scoop will overflow.

The formula for the volume of a sphere is:

V_sphere = (4/3)πr³

where r is the radius of the sphere. In this case, the radius of the ice cream scoop is 3 cm, so:

V_sphere = (4/3)π(3 cm)³ ≈ 113.1 cm³

The formula for the volume of a cone is:

V_cone = (1/3)πr²h

where r is the radius of the base of the cone and h is the height of the cone. In this case, the radius of the cone is also 3 cm and the height of the cone is 5 cm, so:

V_cone = (1/3)π(3 cm)²(5 cm) ≈ 47.1 cm³

Therefore, the volume of the ice cream scoop is greater than the volume of the cone, and the ice cream will overflow when it melts.

To explain this result, we can note that the volume of the ice cream scoop is determined by its shape and size, which cannot be changed. However, the volume of the cone is determined by both its shape and size, as well as the amount of space available inside it. When the ice cream melts, it will fill up the cone and displace the air inside, increasing the volume of the cone. However, the volume of the ice cream scoop will not change, so it will overflow the cone.

The estimates of the statistical measures are given as follows:

a) Variance: 132.84 kg².

b) Mean: 32 kg.

c) x = 42.5.

Before calculating the mean, the absolute frequencies are given as follows, considering the midpoint of each class:

The number of observations is: 7 + 12 + 13 + 10 + 8 = 50.

Hence the relative frequencies are given as follows:

The estimate of the mean is given by the sum of each outcome multiplied by it's relative frequency, hence:

E(X) = 14 x 0.14 + 23 x 0.24 + 32 x 0.26 + 41 x 0.2 + 50 x 0.16 = 32.

For item c, the mean of the 42 non fragile boxes is of 30 kg, and the mean of the fragile boxes is of x, hence the measure x is calculated as follows:

32 = (42 x 30 + 8x)/50

1260 + 8x = 1600

8x = 340

x = 340/8

x = 42.5.

The variance is given by the sum of the differences squared between each observation and the mean, multiplied by their relative frequencies., hence:

V(X) = (14-32)² x 0.14 + (23-32)² x 0.24 + (32-32)² x 0.26 + (41-32)² x 0.2 + (50-32)² x 0.16 = 132.84 kg².

Answer:

1.75 gallons

Step-by-step explanation:

First, we need to calculate how far the hike is going up the trail. They first hike 2 miles and then another 1.75 miles after resting so...

2 + 1.75 = 3.75 miles

The trail is 3.75 miles long, the question states that the return path is 0.5 miles shorter, therefore...

3.75 - 0.5 = 3.25 miles

Leaving us with a total hiking distance of

3.75 + 3.25 = 7 miles.

Since each hiker will carry 0.25 gallons for each mile we simply need to multiply this amount by the total number of miles in the hike.

7 * 0.25 = 1.75 gallons

Finally, we can see that each hiker will carry a total of 1.75 gallons of water for the entire hike.
