Step-by-step explanation:

Deepa would need 6 hours to travel 96 miles at the current speed.

Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.

Since Deepa traveled 32 miles in 2 hours,

her average speed is :

⇒ 32/2

⇒ 16 miles per hour.

To travel 96 miles at this speed, it would take Deepa :

⇒ 96/16

Apply the division operation to get time

⇒ 6 hours.

Therefore, she would need 6 hours to travel 96 miles at the recent speed.

Step-by-step explanation:

Answer:

Simplifying the expression \((3\:.\:2)^5\div (3^2\:.\:2^3)\) so, there is only one power of each base we get \(\mathbf{3^3\:.\:2^2}\)

Option D is correct answer.

Step-by-step explanation:

We need to simply the expression \((3\:.\:2)^5\div (3^2\:.\:2^3)\) so, there is only one power of each base.

Solving:

\((3\:.\:2)^5\div (3^2\:.\:2^3)\)

We can write it as:

\(\frac{(3\:.\:2)^5}{3^2.2^3}\)

Now using exponent rule: \((a\:.\:b)^m=a^m\:.\:b^n\)

\(\frac{3^5\:.\:2^5}{3^2.2^3}\)

Now using the exponent rule: \(\frac{a^m}{a^n}=a^{m-n}\) the bases should be same

\(3^{5-2}\:.\:2^{5-3}\\=3^3\:.\:2^2\)

So, simplifying the expression \((3\:.\:2)^5\div (3^2\:.\:2^3)\) so, there is only one power of each base we get \(\mathbf{3^3\:.\:2^2}\)

Option D is correct answer.

The smallest standard normal quantile value represents the threshold at which a certain proportion of data falls under the normal curve. This quantile value corresponds to the area to the left of it on the curve.

In a standard normal distribution, which has a mean of 0 and a standard deviation of 1, the quantiles represent the values that divide the distribution into equal areas. The quantile value determines the percentage of data that falls below it.

Since the standard normal distribution is symmetric, the smallest quantile value corresponds to the leftmost point on the curve, which is the mean. As the distribution approaches negative infinity, the area under the curve to the left of this point approaches 0.

Therefore, the smallest standard normal quantile value covers an area of 0 under the normal curve. This means that no data falls below this value. In other words, any observation smaller than this quantile value is extremely rare in the standard normal distribution.

Answer:

5 hours

Step-by-step explanation:

If he drove 360 miles in 6 hours, that means he drives 60 miles per hour.

300 divided by 60 is 5, so he will need to drive for 5 more hours

Answer:

5 hours

Step-by-step explanation:

Find his speed in miles per hour:

360/6

= 60

So, his speed is 60 mph

To find how many more hours he would have to drive another 300 miles, divide 300 by 60:

300/60

= 5

So, he would have to drive 5 hours

Therefore, the supplies travel approximately 6.928 feet horizontally on the conveyor belt.

To determine how far the supplies travel horizontally on the conveyor belt, we can use trigonometry.

Given that the second floor is 12 feet higher and the belt makes a 60-degree angle with the ground, we can consider the vertical distance (rise) as the opposite side and the horizontal distance (run) as the adjacent side of a right triangle.

Using the trigonometric function tangent (tan), we can calculate the horizontal distance:

tan(60 degrees) = opposite/adjacent

tan(60 degrees) = 12 feet/run

Rearranging the equation to solve for run:

run = 12 feet / tan(60 degrees)

run ≈ 12 feet / 1.732 (rounded to three decimal places)

run ≈ 6.928 feet (rounded to three decimal places)

The statement "all the curves are concave up" is true.

To show that all the curves are concave up, we first need to find their second derivative.

Here's how we can do that:

4₁60=x³L₂60) = 2³h -1and7L3(x) = ban (2x) ib

Differentiating once with respect to x: x² = L'₁(x)6x² = L'₂(x) = 6h²

Differentiating again with respect to x: 2x = L''₁(x)12x = L''₂(x)

Since the second derivative is always positive, we can conclude that all three curves are concave up.

Answer:

1/4

Step-by-step explanation:which is 2/8 simplified

If the probabilities of their outcomes are 20%, 60%, and 20% respectively, the expected value of these outcomes is $346.

To calculate the expected value of the outcomes, we multiply each outcome by its corresponding probability and then sum up the results.

In this case, the projected outcomes are $240, $310, and $560, with probabilities of 20%, 60%, and 20% respectively.

To calculate the expected value, we use the formula:

Expected value = (Outcome 1 * Probability 1) + (Outcome 2 * Probability 2) + (Outcome 3 * Probability 3) + ...

Expected value = ($240 * 0.20) + ($310 * 0.60) + ($560 * 0.20)

Expected value = $48 + $186 + $112

Expected value = $346

The expected value represents the average value or the long-term average outcome we can expect from the given probabilities and outcomes. It provides a summary measure that helps in understanding the central tendency of the distribution of outcomes.

In this case, the expected value indicates that, on average, we can expect the project's outcome to be around $346.

The exact values of sin(θ), cos(θ), and tan(θ) are -4/5, -3/5 and 4/3 respectively.

The exact values of sin(θ), cos(θ), and tan(θ) is calculated as follows;

sec(θ) = 1/cos(θ)

1/cos(θ) = -5/3

cos(θ) = -3/5

The value of sin (θ) is calculated as follows;

sin²(θ) + cos²(θ) = 1

sin²(θ) + (-3/5)² = 1

sin²(θ) + 9/25 = 1

sin²(θ) = 1 - 9/25

sin²(θ) = 16/25

sin(θ) = ±√(16/25)

sin(θ) = - 4/5

The value of tan(θ) is calculated as follows;

tan(θ) = sin(θ)/cos(θ)

tan(θ) = (-4/5)/(-3/5)

tan(θ)   = 4/3
