write 91.4 million in both standard form and in scientific notation

Answers

Answer 1

91.4 million in standard form is 91400,000.

To express 91.4 million in standard form,

We simply write the number as it is: 91,400,000.

In this form, each place value is clearly represented by its corresponding digit.

In scientific notation, we express the number as a product of a decimal number between 1 and 10, multiplied by a power of 10. For 91.4 million,

It can be written as 9.14 x 10⁷.

In this notation, the decimal point is placed after the first digit, and the power of 10 represents the number of places the decimal point should be moved to the right to obtain the original value.

Suppose the number 1155 is written as the product of three positive integers. What is the smallest possible value of the sum of those three integers?

Answers

3. the equation I used is: 3×5×77

My first thought when I read this problem was "11 is a factor of 1155." Indeed,
1155 equals 11 times 105. Next, determine factors of 105. I see that 5 is a divisor of both 10 and 5, so that 105 equals 5 times 21.

Adding together these three integers: 11+5+21 = 37

But wait! 21 can be factored (e. g., into 7 times 3).

You'll need to identify all of the several sets of 3 positive integers each and find the sum of each set. Only after you've done this can you choose the set whose sum of the three integers is the smallest. Please show your work, so that others can give you feedback on it.

What raw score is at the 34th percentile (34.13 to be exact) when the mean of the distribution is 50 and the standard deviation is 4?

Answers

Let x = the raw score at the 34th percentile.

Given:
μ = 50, the mean
σ = 4, the standard deviation

The z-score is
z = (x - μ)/σ = (x - 50/4

From the normal tables, obtain z = -0.41 for 34% of the area.
Therefore
(x - 50)/4 = -0.41
x - 50 = -1.64
x = 48.36

Answer: 48.36

For the data in the table does Y very directly with X

Example:

Table:

x          y

16        4

32      16

48      36

Direct relation means that the ratio y / x is constant.

So, let's examine this ratio:

Ratio y / x

4/16 = 1/4

16/32 = 1/2

36/48 = 3/ 4

Given that the ratio y/x is not constant, the conclusion is that y does not vary directly with x.

How many faces has an icosahedron?

Final answer:

An icosahedron is a symmetrical, solid shape with 20 triangular faces and 12 corners.

Explanation:

An icosahedron is a symmetrical, solid shape that has 20 faces. Each of these faces is an equilateral triangle. The structure of an icosahedron also includes 12 corners, where the faces meet. This geometric shape is an example of a regular polyhedron, one of the five Platonic solids, which are convex polyhedra with faces made of congruent regular polygons.

The fuel efficiency in miles per gallon of all bmw 320i's is (approximately) normally distributed with a mean of 25 and a standard deviation of 2. a dealer receives a shipment of a random sample of 320i's (random with respect to m.p.g., that is) from the factory. find the probability that average fuel efficiency for this shipment is less than 24 miles per gallon if the dealer receives (i) one car, (ii) four cars and (iii) sixteen cars. explain briefly why these three answers differ.

Answers

Given:
μ = 25 mpg, the population mean
σ = 2 mpg, the population standard deviation

If we select n samples for evaluation, we should calculate z-scores that are based on the standard error of the mean.
That is,
[tex]z= \frac{x-\mu}{\sigma / \sqrt{n} } [/tex]

The random variable is x = 24 mpg.

Part (i): n = 1
σ/√n = 2
z = (24 -25)/2 = -0.5
From standard tables,
P(x < 24) = 0.3085

Part (ii): n = 4
σ/√n = 1
z = (24 -25)/1 = -1
P(x < 24) = 0.1587

Part (iii): n=16
σ/√n = 0.5
z = (24 - 25)/0.5 = -2
P(x < 24) = 0.0228

Explanation:
The larger the sample size, the smaller the standard deviation.
Therefore when n increases, we are getting a result which is closer to that of the true mean.

Show how to multiply 6 x 298 using friendly numbers and then using properties and mental math.Write about which method you like better and why

Answers

Final answer:

To multiply 6 x 298 using friendly numbers, you multiply 6 by 300 and then subtract 12, getting 1788. Using properties and mental math, you break 298 into 200 + 90 + 8, multiply each by 6, and add the results together to get the same answer, 1788. The second method is preferred for its accuracy and reinforcement of the associative property.

Explanation:

To multiply 6 x 298 using friendly numbers, we can adjust 298 to a number that is easier to multiply, such as 300. This method involves approximation for ease of calculation. Here's how it would look:

First, multiply 6 by 300 to get 1800 (since 6 x 3 = 18, and then we add two zeros because we're multiplying by 300).Since we multiplied by 2 more than the original number (298 + 2 = 300), we subtract 2 times 6 from the result (which is 12) to correct for our approximation.Therefore, the final result is 1800 - 12 = 1788.

Using properties and mental math, we can use the distributive property to break 298 into more manageable numbers. Here's the step-by-step process:

Break 298 into 200 + 90 + 8.Multiply each part by 6: (6 x 200) + (6 x 90) + (6 x 8).Calculate each multiplication separately: 1200 + 540 + 48.Add the results together: 1200 + 540 + 48 = 1788.

I prefer the second method because it guarantees accuracy and still takes advantage of the associative property to simplify calculations without approximations. Additionally, this type of mental math helps to reinforce an understanding of multiplication as a series of simpler, added-together parts.

To solve the system of equations, set the demand and supply equation equal to each other and solve for the unknown. Substitute Qd with Qs and solve for P.

Explanation:

We now have a system of three equations and three unknowns (Qd, Qs, and P), which we can solve with algebra. Since Qd = Qs, we can set the demand and supply equation equal to each other:

Qd = 16 - 2PQs = 2 + 5P

By substituting Qd with Qs, we get:

16 - 2P = 2 + 5P

From here, we can solve for P to find the value of the unknown.

Explanation:

First, calculate the total number of ways the books can be arranged on the bookshelf. Since there are 22 books in total, the number of arrangements is 22!.

Next, calculate the number of ways the math books can be arranged together. Since there are 5 math books, the number of arrangements is 5!.

Finally, divide the number of arrangements of the math books by the total number of arrangements to find the probability. So the probability is 5! / 22!.

there are 4 bears. some are black and some are brown. there are fewer than 2 black bears. how many bears are Brown?

Answers

there are 3 brown bears

There are either three or four brown bears, and brown bear > 2 is the inequality that best describes the circumstance.

What is inequality?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

given, there are 4 bears. some are black and some are brown. there are fewer than 2 black bears.

Since,

Black bear < 2

mathematically it can be 0 or 1

the inequality that represents the number of brown bears> 4 - 2

brown bear > 2

theoretically, it could be 3 or 4

therefore, there are either 3 or 4 brown bears, and the inequality that represents the situation is brown bear > 2.
