Solve the equation. First estimate using the perfect square closest to 78 . Then use a calculator. Estimate. n2=78 (the 2 is meaning squared)

The mass of the second box is 4.00 kg.

We can use conservation of momentum to solve this problem. The total momentum before the collision is:

P_before = m₁ × v₁ + m₂ × v₂

where m₁ and v₁ are the mass and velocity of the first box, and m₂ and v₂ are the mass and velocity of the second box. Since the first box is moving west and the second box is moving east, we need to use opposite signs for their velocities:

P_before = 3.00 kg × (-2.00 m/s) + m₂ × 1.50 m/s

Simplify this equation, we get:

P_before = -6.00 kg m/s + 1.50 m/s × m₂

After the collision, both boxes come to a stop, so their final velocities are zero. The total momentum after the collision is therefore:

P_after = 0

By conservation of momentum, the total momentum before the collision must equal the total momentum after the collision:

P_before = P_after

-6.00 kg m/s + 1.50 m/s × m₂ = 0

Solving for m₂, we get:

m₂ = 4.00 kg

in an election debate, two candidates for governor are debating about whether to raise the general sales tax from 5 to 7 percent, so candidate a assumes that the price effect would be larger than the quantity effect.

When a tax is added on a good or service at the point of sale and is financed by the client, it is known as general sales tax. The store is then obligated to transmit, or remit, the tax to the government.

Candidate a contends that revenue will rise along with the sales tax as it rises from 5 to 7 percent. This suggests that the price impact is greater than the quantity effect since, when the tax is raised, the price would rise and the quantity would fall. As a result, the tax revenue would only rise if the price effect is more than the quantity effect.

Additionally, Candidate b claims that the tax will harm consumers and merchants, slow the economy, and reduce tax revenue. However, this claim can only be supported if the quantity effect outweighs the price effect.

Candidate a assumes that the price effect would be larger than the quantity effect.

The approximate area between y=3x^(2)+1 and the x-axis on the interval -1 to 5 is 136.6875.

We can approximate the area between y=3x^(2)+1 and the x-axis on the interval -1 to 5 using a Riemann sum with 4 rectangles of equal width. The left-hand endpoint of each subinterval will be used.

The width of each rectangle is the length of the interval (5-(-1)) divided by the number of rectangles (4). Therefore, the width of each rectangle is

(5-(-1))/4 = 6/4 = 1.5.

Since we are using the left-hand endpoint of each subinterval, the x-values of the left-hand endpoints of the rectangles are

-1, -1+1.5

-1+1.5+1.5

-1+1.5+1.5+1.5 = -1+4.5=3.5

The height of each rectangle is determined by the value of y at the corresponding x-value.

Therefore, the heights of the rectangles are

3(-1)^2+1=2

3(-1+1.5)^2+1=7.125

3(3.5)^2+1=35.125

3(3.5+1.5)^2+1=46.875

The area of each rectangle is the product of its width and height, so the areas of the rectangles are

2*1.5=3

7.125*1.5=10.6875

35.125*1.5=52.6875

46.875*1.5=70.3125.

Therefore, the approximate area between y=3x^(2)+1 and the x-axis on the interval -1 to 5 is 136.6875.

The differences in average flower length among the three Heliconia varieties can be attributed to variations in both mean lengths and standard deviations.

The average flower lengths for the three Heliconia varieties show some differences. Based on the given data, the Bihai variety has the highest mean length of 43.20, followed by the Red variety with a mean length of 39.88, and the Yellow variety with the lowest mean length of 36.68.

To investigate the source of differences in average flower length, we can compare the means and standard deviations for each pair combination:

Bihai vs. Red: The Bihai variety has a higher mean length compared to the Red variety. The difference between their means is 43.20 - 39.88 = 3.32. However, the standard deviation of the Bihai variety (1.213) is smaller than that of the Red variety (1.599), indicating less variability in flower lengths within the Bihai variety.

Bihai vs. Yellow: The Bihai variety also has a higher mean length compared to the Yellow variety. The difference between their means is 43.20 - 36.68 = 6.52. The standard deviation of the Bihai variety (1.213) is again smaller than that of the Yellow variety (1.051), suggesting less variability in flower lengths within the Bihai variety.

Red vs. Yellow: The Red variety has a higher mean length compared to the Yellow variety. The difference between their means is 39.88 - 36.68 = 3.20. The standard deviation of the Red variety (1.599) is larger than that of the Yellow variety (1.051), indicating more variability in flower lengths within the Red variety.

The Bihai variety consistently exhibits the highest mean length, while the Red and Yellow varieties show some differences in mean length and variability.

Given the marginal willingness to pay for oil, the constant marginal cost of extraction, and a discount rate of 1%, the oil reserve will last for approximately 10.8 periods.



To determine how long the oil reserve will last, we need to find the point at which the marginal cost of extraction equals the marginal willingness to pay for oil. In this case, the marginal cost is constant at $4 per unit. The marginal willingness to pay is given by the equation P = 7 - 0.40q, where q represents the quantity of oil extracted.

Setting the marginal cost equal to the marginal willingness to pay, we have:4 = 7 - 0.40q

Simplifying the equation, we get:0.40q = 3

q = 3 / 0.40

q ≈ 7.5So, at q ≈ 7.5, the marginal cost and marginal willingness to pay are equal. We can interpret this as the point at which the country would extract the oil until the quantity reaches 7.5 units. To determine how long this would last, we need to divide the total oil reserve (5 units) by the extraction rate (7.5 units per period):5 / 7.5 ≈ 0.67

Since the extraction rate is less than 1 unit per period, it means that the oil reserve will last for approximately 0.67 periods. However, the discount rate of 1% needs to be taken into account. To calculate the present value of the oil reserve, we discount each period's value. Using the formula for present value, we find that the oil reserve will last for approximately 10.8 periods.

To use the splitpts function in Matlab, you will first need to define two sets of points with different arrays for each set. Then, you can use the syntax newSetOfPoints = splitpts(originalSetOfPoints) to split the original set of points into two new sets.

The "splitpts" function in MATLAB is used to split a set of points into two sets based on a specified split point. Here are the steps to use this function:

1. Define the set of points you want to split. For example:
```
points = [1 2 3 4 5 6 7 8 9 10];
```

2. Specify the split point. This can be any number between the minimum and maximum values of the set of points. For example:
```
splitPoint = 5;
```

3. Use the "splitpts" function to split the set of points into two sets. The first set will contain all the points less than or equal to the split point, and the second set will contain all the points greater than the split point. For example:
```
[set1, set2] = splitpts(points, splitPoint);
```

4. The resulting sets will be stored in the variables "set1" and "set2". You can display these sets using the "disp" function:
```
disp(set1);
disp(set2);
```

The output will be:
```
1 2 3 4 5
6 7 8 9 10

The percent of attendance figures that differs from the mean by 1500 persons or more is 6.68%.

From the question above, Mean μ = 10,000

Standard Deviation σ = 1,000

The formula for z-score is :

z = (x-μ) / σ

Where, x = observation

z = z-score

Mean μ = 10,000

Standard Deviation σ = 1,000

From the above formula, let's calculate z-score for x = 11,500

z = (x-μ) / σ

z = (11,500 - 10,000) / 1000

z = 1.5

Now, find the probability of attendance figures that differs from the mean by 1500 persons or more.

P(z ≥ 1.5) = 0.0668
