Maryam had to sail 4 2⁄3 miles to reach her destination. At the end of the day, she had sailed 3 1⁄3 miles. How far was she from her destination?

Answers

Answer 1

This question is kind of tricky. To make sure, she has to sail 4 2/3 miles but she sailed 3 1/3, how far is she from her destination? Is that what you are saying? If that's what you are saying, then you have to convert both mixed fractions to improper fractions. 4 2/3 will convert to 14/3 (you multiply the whole number times the denominator (the bottom number of the fraction) plus the numerator (the number on the top)) and for 3 1/3 is going to be equal to 10/3. Now that you have both numbers in improper fractions, you can subtract. So 14/3-10/3 is going to give you an equal of 4/3, which would be 1 1/3 in a mixed fraction. YOU'RE WELCOME :D

Answer 2

subtract the distance she traveled from the total distance she has to go

4 2/3 - 3 1/3 = 1 1/3 miles to go

Final answer:

The norms and the inner product of f and g can be calculated using the given inner product definition and the knowledge that the norm of a vector (here, function) is the square root of its inner product with itself. Then, the cosine of the angle between f and g can be found by dividing their inner product by the product of their norms.

Explanation:

The problem is asking us to compute certain components in the context of a vector space of continuous functions, namely inner product ⟨f,g⟩, norms ‖f‖, ‖g‖, and angle between them for f(x) and g(x). Since the functions are given as f(x)=10x^2-3 and g(x)=6x-9, these can be used in the provided inner product definition ⟨f,g⟩=∫from 0 to 1f(x)g(x)dx.

The norm of a vector, in this case, the function f or g, is the square root of the inner product of the function with itself. The cosine of the angle α between the functions f and g is given by the ratio of the inner product of f and g to the product of their norms.

You anticipate that a $2000 investment in a local business will pay an average of 4% interest in each of the next 5 years. Determine to the nearest dollar the amount of the investment at the end of 5 years.

Answers

Since this is a problem in exponential growth/decay, y = ab^x is the formula that will be used to solve this problem.

The initial value, "a", is the value you start out with and in this case, it is $2000.

The growth/decay factor is what "b" represents, and it is 4%. We need to change the percentage into a decimal, so we will take the percent symbol, change it into a decimal, and move it two places to the left. This is make it 0.04. The problem also mentions interest, implying an exponential growth. Therefore, you will add 0.04 by 1: 1+0.04 = 1.04.

The "x" represents an amount of time. It is 5 years. The equation should be written like this:

y = 2000(1.04)^5
y = 2433.30. When rounded to the nearest dollar, it is $2433.

Answers

Given:
μ = 68 in, population mean
σ = 3 in, population standard deviation

Calculate z-scores for the following random variable and determine their probabilities from standard tables.

x = 72 in:
z = (x-μ)/σ = (72-68)/3 = 1.333
P(x) = 0.9088

x = 64 in:
z = (64 -38)/3 = -1.333
P(x) = 0.0912

x = 65 in
z = (65 - 68)/3 = -1
P(x) = 0.1587

x = 71:
z = (71-68)/3 = 1
P(x) = 0.8413

Part (a)
For x > 72 in, obtain
300 - 300*0.9088 = 27.36

Answer: 27

Part (b)
For x ≤ 64 in, obtain
300*0.0912 = 27.36

Answer: 27

Part (c)
For 65 ≤ x ≤ 71, obtain
300*(0.8413 - 0.1587) = 204.78

Answer: 204

Part (d)
For x = 68 in, obtain
z = 0
P(x) = 0.5
The number of students is
300*0.5 = 150

Answer: 150

Final answer:

The student can use the normal distribution and z-scores to estimate the number of students in different height ranges. The heights were estimated to be: about 28 students over 72 inches, 28 students less or equal to 64 inches, roughly 205 students between 65 and 71 inches, and it is statistically impossible to determine exactly 68 inches from the data given.

Explanation:

This question is dealing with a concept in statistics known as the normal distribution. In this context, we are asked to find the proportion of students whose heights fall into various ranges, based on a known mean and standard deviation. With a mean of 68 inches and a standard deviation of 3 inches, we can calculate the z-score for each scenario:

Greater than 72 inches: Z = (72-68)/3 = 1.33. Looking at the z-table, the proportion associated with 1.33 is 0.9082, but we want greater than, so we subtract from 1, giving approximately 0.0918, or 9.18%. Multiply this percentage by the total number of students (300) to estimate the number of students taller than 72 inches. This yields an approximate total of 27.54, but since we cannot have fractional students, we would say approximately 28 students.Less than or equal to 64 inches: Z = (64-68)/3 = -1.33. The proportion for -1.33 on the z-table is 0.0918, which we interpret as 9.18%. This would amount to approximately 27 or 28 students.Between 65 and 71 inches: Calculate two z-scores: Z1 = (65-68)/3 = -1.00 and Z2 = (71-68)/3 = 1.00. Using the z-table, we find that the proportions for z-scores of -1.00 and 1.00 are approximately 0.1587 and 0.8413. So, the proportion between these two z-scores is 0.8413 - 0.1587 = 0.6826, or 68.26%. This correlates to roughly 205 students.Equal to 68 inches: It's impossible to exactly determine the number of students who are exactly 68 inches tall from the data given. The normal distribution is a continuous distribution, and the probability of any single, specific value (like exactly 68 inches) is technically zero. However, you can determine the number of students likely to be in a small range around 68 inches.

A rectangle has side lengths of (3x+6) inches and (2x-4) inches. Write an expression to represent the perimeter of the rectangle. Then find the value of x if the perimeter is 94 inches.

Answers

If I understand the problem correctly, here's the answer:
2 (3x+6) + 2 (2x+4)=94
6x+12+4x+8=94
10x+20=94
10x=74
X=74/10
X=37/5

Answer:

Perimeter: 2(3x+6)+ 2(2x-4)

X=9

Step-by-step explanation:

In order to create the expression you just have to remember that the perimeter of a rectangle equals 2 bases plus 2 sides, so the expression would be:

Perimeter: 2(heights)+ 2(bases)

Perimeter: 2(3x+6)+ 2(2x-4)

IN order to solve for X we just have to insert the value of perimeter, which is 94:

Perimeter: 2(3x+6)+ 2(2x-4)

94=2(3x+6)+ 2(2x-4)

94= 6x+12+4x-8

94=10x+4

94-4=10x

x=90/10

x=9

So the value of x would be 9.

The quotient of a number and ten increased by eleven

Answers

Final answer:

The expression 'The quotient of a number and ten increased by eleven' is written as (x/10) + 11 in mathematical terms. Understanding the role of exponents, such as in the expression 10² equals 100, helps in grasping concepts like scientific notation, where large or small numbers are expressed as the product of a number and a power of ten, such as 1.372568 × 10⁶.

Explanation:

The question 'The quotient of a number and ten increased by eleven' translates to a mathematical expression. This expression can be represented as (x/10) + 11, where 'x' is the number in question. It's a simple algebraic expression where you first divide the number by ten and then add eleven to the result.

When discussing multiplication and division by powers of 10, it's important to understand the concept of an exponent. The exponent is a raised number to the right of the 10, indicating the number of factors of 10 in the original number. For example, in the expression 10², the exponent 2 indicates that ten is multiplied by itself once, resulting in 100. This is consistent with the way our numbering system works, with each place value being ten times greater than the one to its right.

The utility of using exponents is highlighted in scientific notation, which simplifies large or small numbers by representing them as a product of a number and a power of ten. This is particularly useful in fields like science and engineering, where very large or very small numbers are common. For example, the number 1,372,568 can be written in scientific notation as 1.372568 × 10⁶, representing the number as a manageable base multiplied by ten raised to the sixth power.
