How many ways can the letters in the word 'Momentum' be arranged in a row with the 'M's occupying alternate positions?

Let the coordinates of the points be P(h,k). Also, k = 3h + 1. The distance of point P from the origin is equal to the distance of P from (-3, 4). By setting these distances equal to one another and solving, we arrive at the solution.

Answer:

Using a scale of 2" means "will take the original and enlarge it to twice its size".

Thus, the resulting photocopy will be double the dimensions of the original.

Step-by-step explanation:

Answer:

A Type I error could occur if the test shows that the proportion is above 90%, while in reality, the actual proportion is 90%.

Step-by-step explanation:

Machines in a factory produce circular washers that meet a specific diameter.

The quality control manager routinely assesses samples of washers to ensure that more than 90% conform to the specified diameter.

Let p represent the proportion of washers that meet the specified diameter

Thus, Null hypothesis: p = 90%

Alternative Hypothesis: p > 90%

Here, the null hypothesis posits that the proportion is exactly 90%. In contrast, the alternative hypothesis suggests that the proportion exceeds 90%.

Now, a Type I error indicates the probability of rejecting the null hypothesis while it is actually true or, in simple terms, the likelihood of incorrectly rejecting a valid hypothesis.

Thus, based on our question, a Type I error would declare that the test convincingly indicates the proportion is over 90%, while in truth, it remains 90%.

There are 28 combinations. Step-by-step explanation: Initially, each of the seven bins holds one ball, leaving two remaining. If both are placed in the same bin, that offers 7 options. Conversely, if each remaining ball is positioned in different bins, the combination comes down to: 21 + 7 = 28 ways.

Answer:

13%

Detailed breakdown:

Information provided:

• MP = 2080
• Discount = d%
• VAT = (d-2)%
• Cost = 1997.84

Applying the discount:

• 2080 - d% = 2080*(1 - 0.01d)

Including VAT:

• 2080*(1 - 0.01d) + (d - 2)%
• 2080*(1 - 0.01d) * (1 + (d -2)/100)
• 2080*(1 - 0.01d) * (0.98 + 0.01d) = 1997.84
• (1 - 0.01d)(0.98 + 0.01d) = 1997.84/2080
• 0.98 + 0.01d - 0.0098d - 0.0001d² = 0.9605
• - 0.0001d² + 0.0002d + 0.98- 0.9605 = 0
• 0.0001d²- 0.0002d - 0.0195 = 0
• d² - 2d + 195 = 0

Solving this quadratic equation yields:

• d = 15

Therefore

• VAT rate = 15 - 2 = 13%
