How many groups of 1/3 in 9? Evaluate. 9÷ 3 7 ​

Answer: Height = 20 inches, Width = 36 inches

Step-by-step explanation:

Let the height be [tex]h[/tex] and the width be [tex]h+16[/tex].

Using the formula for the perimeter of a triangle,

[tex]2(h+h+16)=112\\\\2(2h+16)=112\\\\2h+16=56\\\\2h=40\\\\h=20 \implies h+16=36[/tex]

The z-score for a weight of 10.7 kg is 1.50, which means that the weight is 1.50 standard deviations above the mean of 10.4 kg.

Height and weight are two measurements used to track a childs development an organization measures child development by comparing the weights of children who are the same height and the same gender in a certain year weights for all 80 cm girls in the reference population had a mean

μ = 10.4 kg

and standard deviation

σ = 0.2 kg.

Weights are normally distributed.

X ~ N(10.4, 0.2). Calculate the z-scores that correspond to the following weights and interpret them. (Round your numerical answers to two decimal places.)

Weight = 10.7 kg

Z-score = 1.50

This means that the weight of 10.7 kg is 1.50 standard deviations above the mean of 10.4 kg.

First, calculate the difference between the weight (10.7 kg) and the mean (10.4 kg):

x - μ = 10.7 - 10.4 = 0.3

Then, divide the difference by the standard deviation:

(x - μ)/σ = 0.3/0.2 = 1.50

The z-score is 1.50, which means that the weight of 10.7 kg is 1.50 standard deviations above the mean of 10.4 kg.

The z-score for a weight of 10.7 kg is 1.50, which means that the weight is 1.50 standard deviations above the mean of 10.4 kg.

The sample proportion based on the question that we have here is 0.85

What is sample proportion?

The sample proportion (p) indicates the percentage of people in a sample who exhibit a particular quality or attribute. Divide the number of individuals (or items) who have the desired attribute by the overall sample size to obtain the sample proportion.

P=X/N, where X represents the number of successes and N represents the sample size, yields the sample proportion.

Hence from the question, we see that 85% of the passengers booked for flights actually show up.  hence the proportion is 0.85.

Answer:

Step-by-step explanation:

Bob would take 5 hours to mow the law by himself.

Let us consider, the area of the lawn to be mowed to be x inch².

It is given that the law can be mowed by Abe alone in 3 hours.

We know that,

Rate of work = Work/Time

⇒ rate of work of Abe = area to be mowed(work)/time taken

                                     = (x/3) inch²/hour

Now,

Abe has been working alone for 1/3 hour

⇒work done by Abe alone = rate of work of Abe x time

                                             = (x/3) inch²/hour x 1/3 hour

                                             = x/9 inch²

Remaining work = x - x/9 = 8x/9 inch²

Let, the rate of work of Bob be y inch²/hour.

It is given that the time taken by Abe and Bob to complete the remaining work together is  1 and 2/3 hours, i.e, 5/3 hours.

Therefore,

The rate of work of Abe and Bob when working together

= work ÷ time

=(8x/9) ÷ (5/3)

=8x/15 inch²/hour

⇒ Rate of work of Abe + Rate of work of Bob = 8x/15

⇒ x/3 + y = 8x/15

⇒ y = (8x/15) - (x/3)

⇒ y = 3x/15 = x/5 inch²/hour

Thus, the time taken by Bob to mow the law by himself

= work ÷ rate of work

= x inch² ÷ (x/5) inch²/hour

= 5 hours

So, it would take 5 hours for Bob to mow the lawn alone.

At x = 2, there is an inflection point and a change in trend (from increasing to decreasing).

The function can change from being "concave up" to "concave down" or vice versa at points known as inflection points. Where the second derivative changes signs can be used to locate them. A point of inflection is defined as the location where the second derivative of a function, f′′, equals zero. To make the geometric significance of this clearer, we must wait a moment. If the curve "bends" upward, a portion of the graph of f has a concave upward slope. For instance, the entire popular parabola y=x2 is concave upward.

Answer:

a= 17

Step-by-step explanation:

Since all sides are equal length, all angles must be equal. Since all of the angles of every triangle sum to 180*, 180/3= 60*. Therefore, (4a-8)*=60*

From there, we can solve for a by adding 8 to both sides:

(4a-8)+8=60+8

4a=68

Then we can divide both sides by 4 to get

(4a)/4= 68/4

a=17

Answer:

a = 17

Step-by-step explanation:

This seems to be an equilateral triangle, so the angle is 60 degrees. 68 - 8 is 60. 4a represents 4 × a, and we know 4 × a has to be 68. 68 / 4 is 17, meaning a = 17.

A linear function in the form of (y = mx + b) to represent the situation is y = 1.5x + 4.

The equation y = 4 + 1.5x is a mathematical representation of the relationship between the two factors that determine the cost of the taxi ride. It is a linear equation, where y is the total cost of the taxi ride, x is the number of miles driven, and the numbers 4 and 1.5 are the coefficients.

In this equation, y is the dependent variable, and x is the independent variable.

The cost of the taxi ride is determined by two factors: the flat fee for the pickup and the additional cost per mile driven.

Let y be the total cost of the taxi ride, measured in dollars.

Let x be the number of miles driven, measured in miles.

The flat fee for the pickup is $4, and the additional cost per mile driven is $1.50.

So, the total cost of the taxi ride, y, is equal to the flat fee plus the additional cost per mile driven multiplied by the number of miles driven.

y = 4 + 1.5x

This can also be written in the form of (y= mx+b) where y is the total cost of the taxi ride, x is the number of miles driven, m is the cost per mile and b is the flat fee or initial cost.

So, the function in the form of (y= mx+b) is y = 1.5x + 4

This is a linear function because the variable x is raised to the power of 1, and the relationship between x and y is a straight line.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given, Rousey Incorporated, had a cash flow to creditors of $16,830 and a cash flow to shareholders of $7,370 over the past year.

Cash flow from assets:

= Cash flow to creditors + Cash flow to shareholders

= $16,965 + $7,559

= $24,524

Since

Net capital spending = Net fixed assets at the end - Net fixed assets at the beginning + Depreciation expense

Cash flow from financial assets = Operating cash flow - Net capital spending - Change in working capital

$24,524 = $51,136 - ($57,130 - $49,705 + $12,252) - Change in working capital

$24,524 = $51,136 - $19,677 - Change in working capital

$24,524 = $31,459 - Change in working capital

Change in working capital = $31,459 - $24,524

Yes, xk/yk converges to x/y. This can be proven mathematically using the definition of a limit.

If xk converges to x and yk converges to y, then the limit of xk/yk as k approaches infinity is equal to the limit of x/y. This can be expressed algebraically as limk→∞xk/yk = limk→∞x/y, which is equal to x/y. Thus, xk/yk converges to x/y.

To calculate this, we can take a sequence of xk an yk values, and divide every xk by its corresponding yk. For example, if xk = {2, 4, 8, 16, 32} and yk = {1, 2, 4, 8, 16}, then the sequence xk/yk = {2/1, 4/2, 8/4, 16/8, 32/16} = {2, 2, 2, 2, 2}. This sequence converges to 2, which is equal to x/y.
