The standard error of mean if o=64 and n=64 will be 8 given the parameters standard deviaion of = 64 and n = 64.

The formula N provides the standard error mean. We must be aware that the standard error means in the given question is denoted by the letter M.

Applying the formula now, we get the following:

σM = 64/√64

64 divided by its square root gives us the number 8.

The standard error means is thus equal to 64 divided by 8, or 8.

We may then conclude that the standard error means will be 8 given the standard error means of = 64 and n = 64.

Answer:

He would have $235

Step-by-step explanation:

If Tom worked 28 hours and earned $9 per hour he would have 252 dollars. Then if he spent $17 dollars he would have $235

Answer:

235

Explanation:

If Tom worked 28 hours last month, and his hourly rate is $9.

Start by multiplying 9 times 28. 9 × 28 = 252

Faster way I do the math is in my head, what is 9*3=27, Add a zero 9×30=270. 30-2=28;2×9=18, Subtract 270-18=252...

Tom spent $17 of his earnings, $252-$17=$235

1. The least number of hours that.Kee can work is 7 hours.

2. The maximum number of miles that Julie will drive will be 272 miles.

1. Lee makes $64 per hour and he wants to make no less than $400 each hours for the trip. The number of hours will be:

Let the number of hours = h

64h >= 400

Divide

h >= 400/64

h >= 6.25

The least hour should be 7 hours.

2. The maximum number of miles that Julie will drive will be:

44(3) + 0.25m = 200

m = number of miles

132 + 0.25m = 200

0.25m = 200 - 132

0.25m = 68

m = 68 / 0.25

= 272

Savannah's grade percentage in the class so far is 92.28%.

Percentage is a measure of frequency that is used in mathematics. The sign that represents percentage is %. In order to convert a number to percentage, multiply the fraction of that amount by 100 or by the given percentage.

Savannah's grade percentage can be determined by adding her percentage score in each component that makes up the total grade.

Percentage score in quizzes = (score obtained / maximum score) x percentage allocated to quizzes

(118 / 150) x 15% = 11.80%

Percentage score in the three exams = (average of the three scores / maximum score) / percentage allocated to exams

Average of the three scores = (73+ 89 + 97) / 3 = 86.33

(86.33 / 100) x 55% = 47.48%

Percentage score in the project = (score in the project / maximum points) x percentage allocated to project

(28 / 25) x 25% = 28%

Percentage score in attendance = 5%

Total grade percentage so far: 5% + 28% + 47.48% + 11.80% = 92.28%

Using the continuity concept, it is found that the function is continuous on the following interval:

C. (0, 1).

A function f(x) is continuous at x = a if it is defined at x = a, and the lateral limits are equal, that is:

[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]

In the context of this problem, the numeric values are especially relevant, as the function not continuous at the zeros of the denominator.

The denominator of the function is given as follows:

(x² - 2)(x + 0.4).

Hence the discontinuity points are:

Hence the only interval in which the function is continuous over the entire interval is given by option C.

The function and the possible options are given by the image at the end of the answer.

) Let us assume that the interest was compounded annually. The formula for calculating compound interest is expressed as

A = P(1 + r/n)^nt

where

A is the amount after t years

P is the principal or initial amount invested

r is the interest rate

n is the number of compounding periods in a year

t is the number of years

From the information given,

P = 130

r = 4% = 4/100 = 0.04

n = 1 because it was compounded once in a year

t = 10

By substituting the values into the formula, we have

A = 130(1 + 0.04/1)^1 * 10

A = 130(1.04)^10

A = 192.43

Rounding to the nearest whole number, the amount after 10 years is $192

We have a random variable, the time it takes to wash the dishes, that is uniformly distributed between 7 minutes and 16 minutes.

We have to calculate the probability that this random variable will have a value between 11 and 15 minutes.

We can calculate this probability as:

We are basically asked to perform the product of expressions that contain complex numbers a s roots of polynomials. So it is essential to identify the complex root in order to facilitate our products that otherwise could be really time consuming.

First product:

(x + 3 + 5i) (x + 3 - 5i) we are going to write as: ((x +3) +5i) ((x+3) - 5i). So this is going to be interpreted as a difference of squares (a + b) ( a - b) = a^2 - b^2:

((x +3) +5i) ((x+3) - 5i) = (x+3)^2 - (5i)^2 = (x+3)^2 - (-25) = (x+3)^2 + 25

We are using the fact that (i)^2 = -1 to convert - 25 (i)^2 = + 25

Now we solve the square of the binomial (x+3) , that is:

(x+ 3)^2 = x^2 + 6x + 9

Now this combined with + 25 gives: x^2 + 6x + 34 This is one of the options in blue background shown at the tops (the fourth one starting from the left)

Second product:

(x - 4i) (x + 4i) which is an easirer product than the one above because we can solve it just using difference of squares: (a - b) (a + b) = a^2 - b^2:

(x - 4i) (x + 4i) = x^2 - (4i)^2 = x^2 - 16 (i)^2 = x^2 +16

This is the second expression in blue background from left to right.

Third product:

(x - 6 + i) (x - 6 - i) for which we apply the same technique as in the first product we solve above:

(x - 6 + i) (x - 6 - i) = ((x - 6) + i) ((x - 6) - i) = (x-6)^2 - (i)^2 = (x-6)^2 - (-1) = (x-6)^2 + 1 = x^2 - 12 x + 36 + 1 = x^2 - 12 x + 37 which is the very first expression in blue background in the image you uploaded.

If we have 45.4 cups of batter, we can make 181 pancakes using unitary method.

The unitary approach is a technique for problem-solving that involves first calculating the value of a single unit, then multiplying that value to figure out the required value.

Given Data

28 cups of batter to make 112 pancakes

To make 1 unit

28 cups of batter = 112 pancakes

1 cup of batter = 4 pancakes

If we have 45.4 cups of batter, we can make,

1 cup of batter = 4 pancakes

45.4 cup of batter = 45.4(4)

45.4 cup of batter = 181 pancakes ( approximately )
