The simplified form of the exponential expression \(64^{\frac{1}{4} }\) is  \(2\sqrt{2}\)

The given expression = \(64^{\frac{1}{4} }\)

The exponential function is the function in the form of f(x)= \(a^{x}\), where x is the variable and a is the constant. The constant term is the base of the exponential function.

The given expression = \(64^{\frac{1}{4} }\)

Here we have to use the power rule of the exponents

\((a^{m})^{n}=a^{mn}\)

To increase a number with an exponent to the power, we have to multiply the exponent times the power

We know

64 = \(2^{6}\)

Then

\(64^{\frac{1}{4} }\) = \((2^{6})^{\frac{1}{4} }\)

Apply the power rule of the exponent

\((2^{6})^{\frac{1}{4} }\) = \(2^{(6)(\frac{1}{4} )}\)

= \(2^{\frac{3}{2} }\)

= \(2\sqrt{2}\)

Hence, the simplified form of the exponential expression \(64^{\frac{1}{4} }\) is  \(2\sqrt{2}\)

The value of the yakubu and bello business is N80,000.

Let's start by determining the original value of Yakubu and Bello's shares in the business before the sale took place.

The ratio of their shares is given as 3:5, which means Yakubu owns 3 parts and Bello owns 5 parts out of a total of 3+5 = 8 parts.

Now, let's assume the value of the business is represented by "V" (to be determined).

Since Yakubu later sold 3/4 of his share to Bello, this means he sold 3/4 * 3 = 9/4 parts of the business to Bello.

The value of 9/4 parts of the business is N180,000, so we can set up the following equation:

(9/4) * V = N180,000

To solve for V, we multiply both sides of the equation by 4/9:

V = (4/9) * N180,000

V = N80,000

Therefore, the value of the business is N80,000.

The dimension of the column space of A is 3.

How the dimension of the column space of A is 3?

The rank-nullity theorem states that for any matrix A, the sum of the dimensions of the null space and the column space is equal to the number of columns in A, i.e.,

dim Null A + dim Col A = number of columns in A

In this case, we have a 8 × 7 matrix A, so the number of columns in A is 7. We are also given that the null space of A is 4-dimensional, i.e., dim Null A = 4. Using the rank-nullity theorem, we can find the dimension of the column space of A:

dim Col A = number of columns in A - dim Null A

dim Col A = 7 - 4

dim Col A = 3

Therefore, the dimension of the column space of A is 3.

Answer:

1. 4\(\frac{2}{3}\)

Step-by-step explanation:

For question 1, you need to know the ratio between the recipe and the amount in question.

So if in the recipe, it says it uses 3/4 cup of diced ham, and the question uses 1 cup of diced ham, you can divide 1 by 3/4 to get 4/3. This is how many times bigger the amount used in the question than the recipe.

Then it asks for how many cups of potatoes, to do this, you look at the recipe and how many potatoes it uses: 3.5 cups

To solve it then, you just do 3.5 x 4/3 to get 4\(\frac{2}{3}\) cups of potatoes

There's your answer.

In 1927 charles lindberg had his first solo flight across the atlantic ocean, then the he fly each hour 107.76 miles/hour.

Based on the given conditions,

In 1927 charles lindberg had his first solo flight across the atlantic ocean.

He flew 3610 miles in 33.5 hours

So,

We can write,

To find out the unit rate, divide the total distance by the total time

Then,

33.5 hours = 3610 miles

1 hour = x miles

Cross Multiply

33.5 hours × x miles = 3610 miles × 1 hour

x miles = 3610 miles × 1 hour/33.5 hours

x miles = 107.76119403 miles

Approximately = 107.76 miles per hour

Therefore,

(a) The mean is expected to be less than the median. (b) Approximately 1.98% of individuals live between 65.38 years and 83.04 years. (c) The smallest interval guaranteed to capture at least 92% of all life expectancies is approximately 5.43 years.

(a) In a skewed-left distribution, the tail of the distribution is elongated to the left, meaning that there are some low values that pull the mean towards the left side of the distribution. In such cases, the mean is usually less than the median.

This happens because the mean is sensitive to extreme values, and when there are a few very low values, they can significantly affect the mean. On the other hand, the median represents the middle value of the data, so it is less affected by extreme values and is generally a better measure of the central tendency in skewed distributions.

Therefore, in this case, we would expect the mean (74.21 years) to be less than the median.

(b) To find the percentage of individuals living between 65.38 years and 83.04 years, we can calculate the z-scores for these values and use the standard normal distribution table. The z-score is calculated as (x - mean) / standard deviation.

For 65.38 years:

z1 = (65.38 - 74.21) / 3.87 = -2.27

For 83.04 years:

z2 = (83.04 - 74.21) / 3.87 = 2.27

Using the standard normal distribution table or a calculator, we can find the area under the curve between these two z-scores. Since the standard normal distribution is symmetric, the area between -2.27 and 2.27 is the same as the area between -2.27 and -(-2.27), which is 2 * P(z < 2.27).

Using the standard normal distribution table or a calculator, we find that P(z < 2.27) is approximately 0.9884.

Therefore, the percentage of individuals living between 65.38 years and 83.04 years is approximately 2 * 0.9884 = 1.9768, which is approximately 1.98% (rounded to two decimal places).

(c) To find the smallest interval guaranteed to capture at least 92% of all life expectancies, we need to find the z-score corresponding to the cumulative probability of 0.92.

Using the standard normal distribution table or a calculator, we find that the z-score corresponding to a cumulative probability of 0.92 is approximately 1.4051.

We can then calculate the interval using the formula:

Interval = z * standard deviation

Interval = 1.4051 * 3.87 = 5.43 (rounded to two decimal places)

Therefore, the smallest interval guaranteed to capture at least 92% of all life expectancies is approximately 5.43 years.

The probability that neither of other two studied calculus is 0.36. The probability that both have taken at least one semester is 0.0759. The probability that at least one has had more than one semester) 0.4782

Let's first find the probability that one of your other two groupmates has studied calculus and the other has not. We can do this by multiplying the probabilities of the two events:

P(one studied calculus, one did not) = P(at least one studied calculus) * P(neither studied calculus)

P(one studied calculus, one did not) = (1 - 0.6) * 0.6

P(one studied calculus, one did not) = 0.24

Since we are dealing with three students in the group, there are three ways that one person could have studied calculus and the other two have not. So we need to multiply the above probability by three:

P(neither of other two studied calculus) = 3 * 0.24

P(neither of other two studied calculus) = 0.72

Therefore, the probability that neither of your other two groupmates has studied calculus is 0.36 (as given), and the probability that at least one has studied calculus is:

P(at least one studied calculus) = 1 - 0.36

P(at least one studied calculus) = 0.64

Now let's find the probability that both of your other two groupmates have studied at least one semester of calculus. This is given to be 0.16. We can break this down into two cases: either both of the other two have taken exactly one semester of calculus, or both have taken two or more semesters. So:

P(both have taken exactly one semester) + P(both have taken two or more semesters) = 0.16

Let's use x to represent the probability that a given student has taken two or more semesters of calculus. Then:

P(both have taken exactly one semester) = 0.29 * 0.29 = 0.0841 (since the two events are independent)

P(both have taken two or more semesters) = x^2

So we have:

0.0841 + x^2 = 0.16

x^2 = 0.0759

x = 0.2758 (taking the positive root since we're dealing with probabilities)

Therefore, the probability that both of your other two groupmates have taken two or more semesters of calculus is approximately:

P(both have taken two or more semesters) = 0.2758^2

P(both have taken two or more semesters) = 0.0759

Finally, we can find the probability that at least one of your other two groupmates has had more than one semester of calculus by subtracting the probability that both have taken exactly one semester from the probability that at least one has studied calculus:

P(at least one has had more than one semester) = P(at least one studied calculus) - P(both have taken exactly one semester)

P(at least one has had more than one semester) = 0.64 - 0.0841

P(at least one has had more than one semester) = 0.5559

P(at least one has had more than one semester) = 0.4782 (rounded to four decimal places)
