If today it was sunny in the morning and raining in the afternoon, and Laura traveled a total of 24 km in 40 minutes, then she is calculated to have rode the electric scooter for  24 minutes in the afternoon.

Let's assume that Laura rode her scooter for x minutes in the morning and for (40 - x) minutes in the afternoon.

In the morning, she traveled a distance of 45 × (x/60) km.

In the afternoon, she traveled a distance of 30 × ((40-x)/60) km.

The total distance traveled is 24 km, so we can set up the equation:

45 × (x/60) + 30 × ((40-x)/60) = 24

Multiplying both sides by 60, we get:

45x + 30(40-x) = 1440

Simplifying and solving for x, we get:

15x + 1200 = 1440

15x = 240

x = 16

Therefore, Laura rode her scooter for (40-16) = 24 minutes in the afternoon.

Step-by-step explanation: your hot

This person has walked a total of 22 miles. The total displacement vector for this walk is 10.06 miles at an angle of 12.58°. If this person walked straight home, they'd have to walk 10.06 miles.

To find the total displacement vector for this walk, we can use the Pythagorean Theorem to find the magnitude of the displacement vector and the direction of the displacement vector.

First, let's find the magnitude of the displacement vector:

d = √((Δx)² + (Δy)²)

Where Δx is the change in the x-direction and Δy is the change in the y-direction.

Δx = 5 + 4cos(45°) + 0 + 3cos(225°) + 4 = 9.83 miles
Δy = 0 + 4sin(45°) + 6 + 3sin(225°) + 0 = 2.17 miles

d = √((9.83)² + (2.17)²) = √(96.58 + 4.71) = √(101.29) = 10.06 miles

So, the magnitude of the displacement vector is 10.06 miles.

Next, let's find the direction of the displacement vector:

θ = tan⁻¹(Δy/Δx) = tan⁻¹(2.17/9.83) = 12.58°

So, the direction of the displacement vector is 12.58°.

Therefore, the total displacement vector for this walk is 10.06 miles at an angle of 12.58°.

If this person walked straight home, they'd have to walk 10.06 miles.

So it will take 20 years for High School R and High School T to have the same enrollment.

Enrollment is the process of registering for classes at a college or university. The process usually involves submitting an application and providing transcripts and other documents to the school.

The enrollment at High School R is increasing by 15 students per year while High School T is decreasing by 10 students per year. To figure out how many years it will take for both schools to have the same enrollment, we need to calculate the difference between the two schools.
High School R currently has 200 students and High School T has 400 students. The difference between the two schools is 200 students (400-200 = 200).
Since High School R is increasing by 15 students per year and High School T is decreasing by 10 students per year, it will take 20 years for the two schools to have the same enrollment.
To calculate this, we divide the difference between the two schools (200 students) by the difference between the two schools' enrollment growth (15 students - 10 students = 5 students). This gives us 200/5 = 40. Since 40 years is too long, we divide 40 by 2 and get 20, which is the answer. So it will take 20 years for High School R and High School T to have the same enrollment.

Answer:

To predict the number of people whose favorite snack is brownies, we need to use the proportion of people in the sample who said brownies were their favorite and apply it to the total number of people attending the reception.

The total number of people in the sample is:

27 + 19 + 74 + 60 = 180

The proportion of people in the sample who said brownies were their favorite is:

27/180 = 0.15

To predict the number of people at the reception whose favorite snack will be brownies, we can multiply the total number of people attending the reception by the proportion of people in the sample who said brownies were their favorite:

3200 x 0.15 = 480

Therefore, we can predict that approximately 480 people at the reception will have brownies as their favorite snack.

Answer: You have to simplify divide by x

Step-by-step explanation:

The slope-intercept form of the equation of the line that has a slope of -1/6 and passes through the point (8,0) is y = -1/6x + 4/3.

To find the slope-intercept form of the equation of the line that has the given slope m and passes through the given point, we can use the point-slope form of a linear equation and then rearrange it to the slope-intercept form.

The point-slope form of a linear equation is given by:

y - y₁ = m(x - x₁)

Where m is the slope and (x₁, y₁) is the point that the line passes through.

In this case, m = -1/6 and the point is (8, 0).

Plugging these values into the point-slope form, we get:

y - 0 = -1/6(x - 8)

To find all zeros for the function f(x) = x3 - 12x? - 13x + 24.

To find all zeros for the function f(x) = x3 - 12x? - 13x + 24, we can use the Rational Root Theorem to find the list of possible rational zeros.

The Rational Root Theorem states that if a polynomial f(x) = anxn + an-1xn-1 + ... + a1x + a0 has integer coefficients, then any rational zero of f(x) must be of the form p/q, where p is a factor of the constant term a0 and q is a factor of the leading coefficient an.

In this case, the constant term is 24 and the leading coefficient is 1. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 1 are 1. Therefore, the possible rational zeros are:

±1/1, ±2/1, ±3/1, ±4/1, ±6/1, ±8/1, ±12/1, ±24/1

Simplifying these fractions gives us the list of possible rational zeros:

±1, ±2, ±3, ±4, ±6, ±8, ±12, ±24

Now, we can use synthetic division to test each of these possible zeros until we find one that gives us a remainder of 0. Once we find a zero, we can factor it out of the polynomial and continue the process with the remaining polynomial until we have found all the zeros.

For example, if we test the possible zero 2, we get:

2 | 1 -12 -13 24
| 2 -20 -66
-----------------
1 -10 -33 -42

Since the remainder is not 0, 2 is not a zero of the function. We can continue testing the other possible zeros until we find all the zeros of the function.

Once we have found all the zeros, we can write them as a list. For example, if the zeros are 3, -2, and 4, we would write:

The zeros of the function are 3, -2, and 4.

Therefore, to find all zeros for the function f(x) = x3 - 12x? - 13x + 24, we can use the Rational Root Theorem to find the list of possible rational zeros, and then use synthetic division to test each possible zero until we find all the zeros of the function.

-2x = -4

x = -4/-2

x = 2

BC = 3x - 1 = 3(2) - 1 = 6 - 1 = 5

we can reject the null hypothesis

Null Hypothesis (H₀): μ ≥ 50

Alternative Hypothesis (H₁): μ < 50

Assumptions:
- A normal distribution for the population of LCBO stores
- A random sample of 20 stores
- A significance level of 0.05

Critical-value approach:

First, calculate the test statistic using the formula:

Test statistic = (Sample Mean - Population Mean) / (Standard Deviation / √Sample Size)

= (41.3 - 50) / (12.2 / √20)

= -2.6

Then, compare this test statistic to the critical-value.

The critical-value is the value that divides the acceptance and rejection regions of the distribution. The critical-value for a two-tailed test with a significance level of 0.05 is ±1.96.

Since -2.6 is less than -1.96, the test statistic falls into the rejection region and we reject the null hypothesis.

p-value approach:

Calculate the p-value using the formula:

p-value = 1 - CDF(test statistic)

Where CDF is the cumulative distribution function.

= 1 - CDF(-2.6)

= 0.004

Since 0.004 is less than 0.05, we reject the null hypothesis.

In conclusion, based on the critical-value approach and the p-value approach, we can reject the null hypothesis and conclude that the population mean sales increase is less than 50 cases.

Using the subtraction, the result of (29v)−(−13v+59) is 42v - 59

The distributive property is a fundamental property of arithmetic and algebra that involves the distribution of a factor across a sum or difference of two or more terms. The property states that when you multiply a number or term by a sum or difference in parentheses, you can distribute the multiplication to each term inside the parentheses and then simplify.

To subtract (29v)−(−13v+59), we first need to distribute the negative sign in front of the parentheses, which will change the signs of each term inside. So, we have

so it will take him a minimum of 3802.5 gallons to drive 117 miles

Dakota would need at least 3.6 gallons of gasoline to drive 117 miles to his brother's house.

A statement that compares two numbers or expressions using an inequality symbol, such as (less than), > (greater than), (less than or equal to), or, is known as an inequality in mathematics (greater than or equal to).

Let x be the volume of gasoline required for Dakota to travel 117 miles to his brother's home. The minimum value of x can be calculated using the inequality shown below:

x ≥ 117 / 32.5

Here, we calculate the bare minimum amount of gasoline Dakota would require to travel 117 miles by dividing the whole distance (117 miles) by the miles per gallon (32.5 miles/gallon).

The inequality is reduced to: x ≥ 3.6

The probability that a person from the survey who has a tablet also has a laptop is 5.8%.

To calculate this, we can use conditional probability. We know that 62% of respondents have a tablet, and 12% of the respondents who have a laptop also have a tablet. So, the probability that a respondent has a laptop given that they have a tablet can be calculated as follows:

We know that P(laptop and tablet) = 0.12 (since 12% of laptop owners also have a tablet), and P(table) = 0.62 (since 62% of respondents have a tablet). So, plugging these values into the formula gives:

However, this is the probability that a person who has a tablet also has a laptop. The question asks for the probability that a person from the survey who has a tablet also has a laptop, which means we need to consider the overall probability of having a laptop, regardless of whether or not they have a tablet. This can be calculated as follows:

P(laptop) = 0.3

So, the probability that a person from the survey who has a tablet also has a laptop, given that they have a laptop, is:

P(laptop|tablet and laptop) = P(laptop and tablet) / P(laptop) = 0.12 / 0.3 = 0.4 or 5.8%
