Answer:

  110 square inches

Step-by-step explanation:

First, recall the formula for the area of a trapezoid:

  A = (1/2)(b1 +b2)h

Next, identify the base and height dimensions on the figure.

  b1 = 13 in; b2 = 9 in; h = 10 in

Next, fill the numbers into the formula and do the arithmetic.

  A = (1/2)(13 in + 9 in)(10 in) = (1/2)(22 in)(10 in) = 110 in^2

Last, answer the question asked.

  The area of the trapezoid is 110 square inches.

The force acting on a beam was measured 5 times under the same operating conditions. This process was repeated by 3 observers, resulting in 3 sets of data. The standard deviations of these data sets were: Standard Deviation 1= 1.11, Standard Deviation 2= 0.99, Standard Deviation 3= 1.15 The corresponding mean values were: 52.3, 51.5, and 52.7, respectively. Compute the Pooled Standard Deviation for these data sets. (Provide your answer using two decimal places)

Answers

Answer:

The Pooled Standard Deviation for these data sets is 1.09

Step-by-step explanation:  

Given that;

Standard Deviation 1 = 1.11

Standard Deviation 2 = 0.99

Standard Deviation 3 = 1.15

pooled standard deviation is given as;

[tex]S_{pooled}[/tex] = (n1 - 1 )s1² + ..... + ( nk - 1 )sk² / n1 + ..... + nk - 1

where n1, n2....., nk are the sample sizes of k groups and s1, s2, ....., sk are the standard deviations of k groups respectively

so for the 3 groups;

[tex]S_{pooled}[/tex]² =   (n1 - 1 )s1² + (n2 - 1 )s2² + ( n3 - 1)s3² / n1 + n2 + n3 - 3

we substitute

[tex]S_{pooled}[/tex]² =   (5 - 1 )1.11² + (5 - 1 )0.99 ² + ( 5 - 1)1.15² / 5 + 5 + 5 - 3

[tex]S_{pooled}[/tex]² =   (4.9284 + 3.9204 + 5.29) / 12

[tex]S_{pooled}[/tex]² =   14.1388 / 12

[tex]S_{pooled}[/tex]² =   1.1782

[tex]S_{pooled}[/tex] = √1.1782

[tex]S_{pooled}[/tex] = 1.08544 ≈ 1.09

Therefore, The Pooled Standard Deviation for these data sets is 1.09

Growth

Step-by-step explanation:

Given

[tex]\frac{2}{3}(2.5)^x[/tex]

Required

Growth or decay

The general form is:

[tex]y = ab^x[/tex]

Such that:

[tex]b = rate[/tex]

For b, we have the following conditions:

[tex]b > 1[/tex] ----- Growth

[tex]0<b <1[/tex] --- Decay

[tex]b = 1[/tex] ---- None

Compare [tex]\frac{2}{3}(2.5)^x[/tex] to [tex]y = ab^x[/tex]

[tex]b = 2.5[/tex]

Because 2.5 > 1, then the first condition applies (growth)

Solve the system of linear equations by elimination. 8x-5y=11 4x-3y=5

Answers

Answer:

(x,y)= ( 5 over 273, - 265 over 273)

Step-by-step explanation:

After solving the obtained equation with the elimination method the obtained value of x and y will be 2 and 1 respectively.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that,

8x-5y=11  ------ (1)

4x-3y=5 --------- (2)

In order to solve the above equation with the elimination method, we have to apply the multiplicative distribution law as,

Multiply by 2 in equation 2

2(4x-3y=5)

8x- 6y = 10  ----- (3)

Subtract equation 3 from equation 1,

(8x- 6y)-(8x-5y) = 10 - 11

8x-8x-6y+5y = -1

-y = -1

y=1

Substitute the value of y in any of the equations 1  to get the value of x

8x-5y=11

8x-5(1)=11

8x-5=11

8x=16

x=2

Thus, after solving the obtained equation with the elimination method the obtained value of x and y will be 2 and 1 respectively.

Which statement is true based on the graph ?

Answers

Answer:

C: The speed increases from A to F

Step-by-step explanation:

Check each node A to F including A and F.

B is higher than A, C is higher than B, ...

This is true for all of them, so it is increasing.

The speed of the car is increasing in the time interval from point A to point F. Option C is correct.

What is speed?

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

What is the graph?

The graph depicts the relationship between the x and y axes through the use of curves.

Here,
The graph shows the speed and time relation of the car,
Where,
The speed of the car is increasing from A to F,
The speed of the car is decreasing from F to G,
The speed of the car is increasing from G to H,
The speed of the car is decreasing from H to K,

Thus, the car's speed increases over the time span from point A to point F. Option C is the right answer.

What is the minimum of the sinusoidal function?

Answers

Answer: The minimum is -4.

Step-by-step explanation:

The minimum of a function:

y = f(x)

will be the smallest value of y that the function gives.

such that, if the minimum is y = m

m ≤ f(x)   ∀ x

In this case, we can see that the smallest value of y is:

y = -4

Then the minimum of the sinusoidal function is -4.

Write a classification essay to describe two types of animal flight​

Answers

Do pidgins and eagles

One of the two basic types of animal locomotion: powered flight, actual flight, or gliding. Real wings are only found in most bird species, most insect orders, and bats.

What are the categories?

A category listing is a list of various product categories, such as children's clothing, women's clothing, and men's clothing. Any form of a category can be simply created

Soaring and gravitational gliding are two distinct types of gliding flight.

In controlled gravitational gliding, a creature propels itself in a precise direction after delaying its descent and relying on the wind for horizontal motion (parachuting).

Adaptations for guided gliding are primarily made to increase glide ratio (the amount of horizontal distance covered per unit descent)

Therefore, powered flight or true flight are the two basic categories of animal locomotion.

A profit of a football club after a takeover is modeled by p(t) = t3 - 14t2 + 20t + 120, which t is the number of years after the takeover. In which years was the club making loss?

Answers

t = 5, so after 5 years
p(t) = t^3 - 14t^2 + 20t + 120

Take derivative to find minimum:
p’(t) = 3t^2 - 28t + 10

Factor to solve for t:
p’(t) = (3t - 2)(t - 5)
0 = (3t - 2)(t - 5)

0 = 3t - 2
2 = 3t
2/3 = t

Plug 2/3 into original equation, this is a maximum. We want the minimum:

0 = t - 5
5 = t

Plug back into original:
5^3 - 14(5)^2 + 20(5) + 120
125 - 14(25) + 100 + 120
125 - 350 + 220
- 225 + 220
p(5) = -5

The club losses during the years 4.89 years<t<11.29 years.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given,

Profit of a football club after a takeover is modeled by p(t) = t³ - 14t² + 20t + 120,

t is the number of years after the takeover

We need to find in which  years was the club making loss

p(t) = t³ - 14t² + 20t + 120,

the profit is negative when the club is in loss.

Plot the cubic equation

The profit p(t) is negative in the interval (4.89,11.29)

The number of years t cannot be a negative number

Hence the club lost during the years 4.89 years<t<11.29 years.

Answers

Answer:

It will take $ 989.59 in Canadian funds to buy $ 800.

Step-by-step explanation:

If one Canadian dollar is equivalent to US $ 0.8150, in order to determine how much money is needed in Canadian funds to buy US $ 800.00 the following calculation must be performed:

0.8150 = 1

800 = X

(800 x 1) / 0.8150 = X

800 / 0.8150 = X

981.59 = X

Therefore, it will take $ 989.59 in Canadian funds to buy $ 800.
