-273/90 in simplest form

The probability that a randomly selected woman will be 60 inches or less is approximately 0.0139, or 1.39%.

To find the probability that a randomly selected woman will be 60 inches or less, we need to calculate the area under the normal distribution curve up to the value of 60 inches. We can do this by standardizing the value using the z-score formula and then looking up the corresponding probability from a standard normal distribution table or using a calculator.

First, we calculate the z-score:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

z = (60 - 65.5) / 2.5 = -2.2

Next, we find the probability associated with the z-score using the standard normal distribution table or calculator. From the table or calculator, we find that the probability of having a z-score less than -2.2 is approximately 0.0139.

Answer: 3.5

Step-by-step explanation:  33.20-29.7

She was initially at a depth of 90.9 feet before she dropped.

We have,

A scientist was in a submarine below sea level, studying ocean life.

And, Over the next ten minutes, she dropped 62 feet.

To get her initial depth, we need to understand how many feet she sank and dropped.

Let us say she was initially at a depth which we can call  = x feet.

After 10 minutes she dropped for 62 feet.

This means her new depth will be x - (- 62) = (x + 62) ft.

We are also told that this new depth is actually 157.9 feet below sea level.

This means

x + 62 = 157.9

Now that we have this equation we can simply make x the subject of the formula and solve for x

x = 157.9 - 67

x = 90.9

Thus, She was initially at a depth of 90.9 feet before she dropped.

There are 120 apples in each basket and 2 leftovers

From the question, the given parameters are:

Number of apples = 482

Number of baskets = 4

the number of apples in each basket is calculated as

Apples in each basket = Number of apples/Number of baskets

Substitute the known values in the above equation

So, we have the following equation

Apples in each basket = 482/4

Evaluate

Apples in each basket = 120.5

Remove the decimal

Apples in each basket = 120

In (a), we have

Apples in each basket = 120.5

The decimal part is

Decimal = 0.5

The number of leftover is then calculated as

Leftover = Decimal * Baskets

So, we have

Leftover = 0.5 * 4

Evaluate

Leftover = 2

Hence, there are 2 leftovers

The number of each type of coins are as follows:

q = 15 quarters.

d = 30 dimes.

n = 25 nickels.

In order to solve this word problem, we would assign a variables to the unknown numbers and then translate the word problem into algebraic equation as follows:

Let d represent the number of dimes.

Let q represent number of quarters.

Let n represent number of nickels.

Let T represent total number of coins.

Note: 1 quarter is equal to 0.25 dollar, 1 nickel is equal to 0.5 dollar, and 1 dime is equal to 0.1 dollar.

Translating the word problem into an algebraic equation, we have;

Dimes; d = 2q     .....equation 1.

Nickels; (70 - (q + 2q)) = (70 - 3q)     .....equation 2.

Total coins; T = n + d + q

0.5(70 - 3q) + 2q(0.1) + q(0.25) = 8.00

Multiplying all through by 100, we have:

5(70 - 3q) + 2q(10) + q(25) = 800

350 - 15q + 20q + 25q = 800

350 + 30q = 800

30q = 800 - 350

30q = 450

q = 450/30

q = 15 quarters.

For the number of dimes, we have:

Dimes, d = 2q

Dimes, d = 2(15)

Dimes, d = 30 dimes.

For the number of nickels, we have:

Nickels, n = (70 - 3q)

Nickels, n = (70 - 3(15))

Nickels, n = (70 - 45)

Nickels, n = 25 nickels.

3+6p≥25  is the inequality  to represent this situation, where p represents the number of packages of shirts and The minimum number of whole packages of shirts that Ms. Clark needs to buy are 4.

a relationship between two expressions or values that are not equal to each other is called 'inequality.

Given that Each student in Ms. Clark's class is decorating a shirt for a school program

The number of students in the Clarks class are 25.

Ms. Clark already has 3 shirts. She will buy shirts In packages of 6 shirts. She cannot buy part of a package.

we need to Create an inequality using only the given numbers to represent this situation, where p represents the number of packages of shirts.

3+6p≥25 is the required inequality.

Now the  minimum number of whole packages of shirts that Ms. Clark needs to buy.

The probability of a bulb lasting for between 557 and 561 hours is roughly 0.0382 or 3.82%

Able to utilize the standard ordinary dissemination to discover the likelihood of a bulb enduring for between 557 and 561 hours. To do this, we ought to standardize the values utilizing the equation:

z = (x - μ) / σ

where x is the bulb lifetime we're fascinated by

, μ is the cruel(mean) lifetime,

and σ is the standard deviation.

For 557 hours:

z1 = (557 - 530) / 15 = 1.8

For 561 hours:

z2 = (561 - 530) / 15 = 2.07

Employing a standard ordinary conveyance table or a calculator with a typical dissemination work, we are able to discover the probabilities corresponding to these z-scores:

P(z1 < Z < z2) = P(1.8 < Z < 2.07)

This speaks to the likelihood of a bulb enduring between 557 and 561 hours, where Z could be a standard ordinary variable.

Employing a standard ordinary dispersion table or a calculator, we discover:

P(1.8 < Z < 2.07) ≈ 0.0382

Therefore, the likelihood of a bulb enduring for between 557 and 561 hours is roughly 0.0382 or 3.82% (adjusted to four decimal places).

The statement, if function, (x,y) = f(x) ·f(y) for all (x,y) such that f(x,y) > 0, then x ⊥⊥y is true.

By definition, two random variables x and y are said to be independent (denoted as x ⊥⊥ y) if the joint probability distribution function f(x, y) can be expressed as the product of the marginal probability distribution functions f(x) and f(y) for all values of x and y.

In this case, if we have f(x, y) = f(x) · f(y) for all (x, y) such that f(x, y) > 0, it implies that the joint probability distribution function can be factorized into the product of the marginal probability distribution functions. Therefore, x and y are independent, and we can conclude that x ⊥⊥ y.

Thus, Brian's average speed for the whole journey from Ashton to Oldham is 34.29 mph.

Average, also known as mean, is a measure of central tendency in statistics that represents the typical value of a set of numbers. It is calculated by adding up all the numbers in the set and then dividing the sum by the total number of values in the set. For example, if you want to

Given by the question.

To calculate the average speed of Brian's whole journey, we need to use the formula:

average speed = total distance ÷ total time

We know the distance between Ashton and Lees is 12 miles, and we also know the speed at which Brian drove this part of the journey: 40 mph. Using the formula:

time taken = distance ÷ speed

we can calculate that it took Brian:

time taken from Ashton to Lees = 12 miles ÷ 40 mph = 0.3 hours

We also know the distance between Lees and Oldham is 12 miles, and the speed at which Brian drove this part of the journey: 30 mph. Again using the formula:

time taken from Lees to Oldham = 12 miles ÷ 30 mph = 0.4 hours

So, the total distance Brian covered from Ashton to Oldham is:

total distance = distance from Ashton to Lees + distance from Lees to Oldham

total distance = 12 miles + 12 miles = 24 miles

The total time Brian spent on the journey is:

total time = time taken from Ashton to Lees + time taken from Lees to Oldham

total time = 0.3 hours + 0.4 hours = 0.7 hours

Now we can use the formula for average speed:

average speed = total distance ÷ total time

average speed = 24 miles ÷ 0.7 hours

average speed = 34.29 mph

The correct statement is B. For all b, the equation Ax=b has a solution.

Since the columns of A are linearly independent, then the matrix A has full rank, and its column space is equal to the entire vector space in which it resides. This means that for any given vector b, we can find a linear combination of the columns of A that is equal to b, and therefore the equation Ax=b has a solution for all b.

Option A is incorrect, as there may be certain b vectors for which Ax=b has a solution.

Option C is incorrect, as the equation Ax=b may have a solution even when A has fewer columns than rows.

Option D is incorrect, as we can determine whether or not the equation Ax=b has a solution for all b by checking the rank of A.

Option E is incorrect, as the equation Ax=b may have a solution even when A has more columns than rows.

Option F is incorrect, as a square matrix may or may not have linearly independent columns, and therefore may or may not have a solution for all b.
