a. Diego's mistake was that he multiplied the exponents rather than adding them.

b. His answer should be 2^5 which is 32.

In mathematics, an exponent refers to the number of times a base number is multiplied by itself. It is a way of expressing repeated multiplication. The exponent is usually written as a superscript to the right of the base number.

For example, in the expression 2³, 2 is the base and 3 is the exponent. This means that 2 is multiplied by itself three times: 2 × 2 × 2 = 8. So, 2³ is equal to 8.

Diego's mistake was that he multiplied the exponents rather than adding them. The answer should be 32.

the greatest possible product of a four-digit number and a three-digit number obtained from seven distinct digits is 2,463,534.

To find the greatest possible product of a four-digit number and a three-digit number obtained from seven distinct digits, we can start by considering the largest possible values for each digit.

Since we need to use seven distinct digits, let's assume we have the digits 1, 2, 3, 4, 5, 6, and 7 available.

To maximize the product, we want to use the largest digits in the higher place values and the smallest digits in the lower place values.

For the four-digit number, we can arrange the digits in descending order: 7, 6, 5, 4.

For the three-digit number, we can arrange the digits in descending order: 3, 2, 1.

Now, we multiply these two numbers to find the greatest possible product:

7,654 * 321 = 2,463,534

The estimated probability of the total sum being at least 360 is approximately 8%.

To estimate the probability using a normal approximation with a continuity correction, we first need to find the mean and standard deviation of the sum of the numbers on the 50 dice.
For a single 12-sided die, the mean is (1+2+...+12)/12 = 6.5. For 50 dice, the mean is 50 × 6.5 = 325. The variance for one die is [(1-6.5)²+(2-6.5)²+...+(12-6.5)²]/12 = 11.92. For 50 dice, the variance is 50 × 11.92 = 596, and the standard deviation is √596 ≈ 24.4.
Now, we'll use the normal approximation with a continuity correction to estimate the probability that the sum of the numbers is at least 360. First, find the z-score:
z = (X - μ + 0.5) / σ = (360 - 325 + 0.5) / 24.4 ≈ 1.42
Using a z-table or calculator, the probability of obtaining a z-score greater than 1.42 is approximately 0.0778 or 7.78%. The closest percentage in the options provided is 8%, which corresponds to option g. Therefore, the estimated probability of the total sum being at least 360 is approximately 8%.

Answer:

∠1 = 126°

∠4 = 54°

∠7 = 126°

Step-by-step explanation:

Since line p and line q are parallel lines we can use the angle relations to find the missing angle measures.

∠1 and ∠3 are alternate and congruent, so their measures are equal and 126° each.

∠4 and ∠3 are making a straight line and are supplementary angles, so their sum is adding up to 180°.

To find ∠4 we need to subtract 126 from 180:

180 - 126 = 54°

∠7 and ∠3 are corresponding angles and so they are equal in measurement and 126° each.

The probability of rolling a 5 on a 6-sided die three times in a row is 1/216.

To find the probability of rolling a 5 all three times with a 6-sided die, we need to determine the probability of rolling a 5 once and then raise that to the power of 3.

Step 1: Find the probability of rolling a 5 on a single roll. There is 1 favorable outcome (rolling a 5) and 6 possible outcomes (the numbers 1 through 6). So, the probability is 1/6.

Step 2: Calculate the probability of rolling a 5 three times in a row. Since the rolls are independent events, we can multiply the probabilities together: (1/6) * (1/6) * (1/6) = 1/216.

When rolling a 6-sided die three times, the probability of rolling a 5 all three times is 1/216. This is because the probability of rolling a 5 once is 1/6, and the events are independent, so we multiply the probabilities together.

The probability of rolling a 5 on a 6-sided die three times in a row is 1/216.

The area of the semicircle is approximately 57 square feet.

The arc length of the semicircle can be found using the formula:

arc length = (θ/360) × 2πr

where θ is the angle in degrees, r is the radius, and π is approximately 3.14.

In this case, the diameter of the semicircle is 12 feet, so the radius is half of that, or 6 feet. The angle of the semicircle is 180 degrees, since it is a semicircle. Plugging these values into the formula, we get:

arc length = (180/360) × 2π(6) ≈ 18.85 feet

Therefore, the arc length of the semicircle is approximately 19 feet.

To find the area of the semicircle, we can use the formula:

area = (πr^2)/2

Plugging in the value of the radius from before, we get:

area = (π(6^2))/2 ≈ 56.55 square feet

Therefore, the area of the semicircle is approximately 57 square feet.

In 2013, an Ipsos Global poll conducted for Reuters News found that 63% of 1,000 Canadians supported the legalization of same-sex marriage, who support legalization is 50%, and the alternative hypothesis (Ha: pi not = 0.50) that suggests the population proportion is different from 50%.

a) The standard error measures the variability or uncertainty of the sample proportion compared to the true population proportion. It can be calculated as the square root of (pi * (1 - pi)) divided by the sample size. In this case, the standard error would be computed to estimate the proportion of Canadians who support same-sex marriage.

b) To test the hypothesis, we need to calculate the test statistic. The test statistic for this scenario is the z-score, which is calculated by subtracting the hypothesized population proportion from the sample proportion and dividing it by the standard error. This provides a measure of how many standard errors the observed proportion differs from the hypothesized proportion.

c) By determining the test statistic, we can find the associated p-value. The p-value represents the probability of observing a test statistic as extreme as the one calculated, assuming the null hypothesis is true. If the p-value is less than the significance level (e.g., 0.05), we can reject the null hypothesis. In this context, the p-value would indicate the strength of evidence against the claim that the population proportion is 50%.

The equation  2/(√12-√8) can be written in the form of √a+√b, where a and b are integers whose values are 3 and 2

The given equation is-

2/(√12-√8)

As, it is clear that the denominator part contains the irrational number.

Thus, to eliminate the irrational part, divide and multiply the equation by (✓12 + ✓8).

= 2/(✓12-✓8) × (✓12 + ✓8)/(✓12 + ✓8)

Further simplify;

= 2(✓12+✓8)/(12-8)

= 2(✓12+✓8)/4

= (✓12+✓8)/2

= ✓12/2 + ✓8/2

On further simplification;

✓3 + ✓2

Comparing the result with √a+√b, a is written as 3 while b is found as 2.

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

The number of batch recipe calls for 1 / 2 lb of flour = 1 batch

And to calculate the number of batches , we use

The number of batch recipe calls for 1 lb of flour will be

1 / 2 lb of flours = 1 batch

Multiplying by 2 on both sides , we find the number of batches for 1 lb of flour

Therefore , 1 / 2 x 2 = 1 x 2

1 lb of flour = 2 batches

3 / 4 lb of flour is 1 x 3 / 4 = 2 x 3 / 4

                                          = 3 / 2 batches

                                          = 1.5 batches

1 / 4 lb of flour is 1 x 1 / 4 = 2 x 1 / 4

                                        = 1 / 2 batches

                                        = 0.5 batch

if Mike draws a card randomly, he has a 40% chance of getting a grade of "A".

The probability of an event is a numerical measure of the likelihood that the event will occur. It is expressed as a fraction or decimal between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur. In this case, the event is Mike getting a grade of "A" on the oral exam, and the probability of this event is calculated as the number of favorable outcomes (cards with answers known by Mike) divided by the total number of possible outcomes (all 20 cards).

So, if Mike draws a card randomly from the set of 20 cards, he has a chance of 8/20 = 2/5 = 0.4 or 40% of answering all 3 questions correctly and getting a grade of "A". This means that if the experiment of drawing a card and answering the questions is repeated many times, Mike is expected to get a grade of "A" in 40% of those instances. The probability of Mike getting a grade of "A" is equal to the number of favorable outcomes (cards with answers known by Mike) divided by the total number of possible outcomes (all 20 cards).

Since Mike knows the answers to all 3 questions on 8 cards, the probability of him getting a grade of "A" is:

P(A) = 8/20 = 2/5 = 0.4 or 40%

So, if Mike draws a card randomly, he has a 40% chance of getting a grade of "A".
