Answer:

I think

"Quadriplegia" would go with a "spinal cord injury".

Quadriplegia is a spinal cord injury that causes you to lose feelings in all four limbs.

A "knee injury" would go with "Limited ability to walk and run."

"Headaches" with "traumatic brain injury."

Hope this helps!

Answer:

Quadriplegia-Spinal cord injury

Headaches-Traumatic brain injury

Limited ability to walk and run-Knee injury

Step-by-step explanation:

Quadriplegia is the state in which a person can´t move any of its extremities, this is often cause by an accident to the spinal cord and it causes the nerves that connect the brain and the muscles in the bosy to stop functioning properly.

Headaches can be the consequence of a traumatic brain injury that didn´t healed well.

A knee injury often has as result the limited ability to walk and run.

Simplify -5 + 9 to 4

ANSWER

C. 145.75 yd²

EXPLANATION

First we need to calculate the area of the four triangular faces.

The lateral surface area

[tex] = 4 \times \frac{1}{2} \times 5.3 \times 11.1[/tex]

[tex] = 117.66 {yd}^{2} [/tex]

The area of the base is

[tex] = 5.3 \times 5.3[/tex]

[tex] = 28.09[/tex]

To find the total surface area, we add the area of the square base to the area of the 4 triangular faces.

Therefore the total surface area is

[tex] = 117.66 + 8.09 = 145.75 {yd}^{2} [/tex]

Answer: Option C.

Step-by-step explanation:

To calculate the surface area of the right square pyramid, you need to use the following formula:

[tex]SA=\frac{1}{2}(4s)(l)+(s^2)[/tex]

Where  "s" is the length of any side of the base and "l" is the slant height.

You can identify in the figure that:

[tex]s=5.3yd\\l=11.1yd[/tex]

Therefore, substituting these values into the formula, you get this result:

[tex]SA=\frac{1}{2}(4(5.3yd))(11.1yd)+((5.3yd)^2)\\\\SA=145.75yd^2[/tex]

Answer: Third option

[tex]P = 0.354[/tex]

Step-by-step explanation:

We have an elevator with 5 men and 7 women. We want to find the probability that 3 women and one man will come down from the elevator.

To calculate this probability we can use combinations.

The formula of combinations is:

[tex]nCr = \frac{n!}{r!(n-r)!}[/tex]

Where you can choose between n people and choose r from them.

First we calculate all the possible results of the experiment.

That is, the amount of ways to select 4 people from a group of 12 people.

[tex]12C4 = \frac{12!}{4!(12-4)!} = 495[/tex]

There are 495 results.

Now we calculate the possible number of ways to obtain the desired result, that is 3 women and one man.

The possible combinations of selecting 3 women from a group of 7 is.

[tex]7C3 = \frac{7!}{3!(7-3)!} = 35[/tex].

The possible combinations of selecting 1 a man from a group of 5 is

[tex]5C1 = \frac{5!}{1!(5-1)!} = 5[/tex]

Then the number of ways in which 3 women and one man can be obtained is:

[tex]7C3 * 5C1 = 35 * 5 = 175[/tex]

Finally the probability is:

P = Number of ways to obtain the desired result ÷ possible number of results

[tex]P = \frac{7C3 * 5C1}{12C4}\\\\P = \frac{175}{495}[/tex]

[tex]P = 0.354[/tex]

Answer:

  10 and 14

Step-by-step explanation:

You need only check the answers to see which one satisfies the problem requirements. The differences between the second and first numbers are ...

  8, 4, 2, -6

Only one pair has the second number 4 more than the first: 10 and 14.

Since you are given variable definitions, perhaps you're expected to write and solve equations.

  a + b = 24 . . . . . the sum of the two numbers is 24

  -a +b = 4 . . . . . . the second number is 4 more than the first

Adding these two equations gives ...

  (a +b) +(-a +b) = (24) +(4)

  2b = 28 . . . . .  simplify; next, divide by 2

  b = 14 . . . . . . .  identifies 10 and 14 as the correct answer

The median of the data set is 6.0.

Complete question:

What is the median of the data set? History Test Scores 5 0 8 6 5 6 8 9 7 0 3 5 8 8 0 6 7 7 7 9 0 1 3 5 6 8 9 9 5 0 = 50 points

The median of the data set is 86

How to find the median

To find the median of a data set, you need to arrange the data in ascending order (from smallest to largest) and then find the middle value.

In the stem and leaf plot, we have to express the numbers as follows

50 53 65 64 75 77 78 82 84 85 86 87 87 90 91 92 93 94 96 97 99

The data set is 21. The meidan is the number in the middle. This will be the 11 position in this case

The number in the 11th positon here is 86

The answer is:

The total time traveled is equal to 9 hours.

To solve the problem, we need to write two equations using the given information about the travel upstream and downstream.

So, we need to write two equations:

Let be "x" the speed of the cabin cruiser (12 mph in still water)

Let be "y" the speed of the current (4 mph).

Then,

For the travel against the current (upstream), we have:

[tex](x-y)*t_{upstream}=48miles\\\\(x-y)*t_{upstream}=48miles\\\\(x-4mph)*t_{upstream}=48miles[/tex]

For the travel with the current (downstream), we have:

[tex](x+y)*t_{downstream}=48miles\\\\(x+y)*t_{downstream}=48miles\\\\(x+4mph)*t_{downstream}=48miles[/tex]

Also, we know that the speed of the cruise traveling in still water is equal to 12mph.

So,

Calculating the time traveled upstream, we have:

[tex](x-4mph)*t_{upstream}=48miles[/tex]

[tex](12mph-4mph)*t_{upstream}=48miles[/tex]

[tex](8mph)*t_{upstream}=48miles[/tex]

[tex]t_{upstream}=\frac{48miles}{8mph}=6hours[/tex]

Calculating the time traveled downstream, we have:

[tex](x+4mph)*t_{downstream}=48miles[/tex]

[tex](12mph+4mph)*t_{downstream}=48miles[/tex]

[tex](16mph)*t_{downstream}=48miles[/tex]

[tex]t_{downstream}=\frac{48miles}{16mph}=3hours[/tex]

Now that we know the time traveled upstream and downstream, we need to calculate the total time traveled using the following equation:

[tex]TotalTime=t_{upstream}+t_{downstream}\\\\TotalTime=6hours+3hours=9hours[/tex]

Hence, we have that the total time traveled is equal to 9 hours.

Have a nice day!

Answer:

- [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [ - 4, 1 ]

f(b) = f(1) = - 4 ← value from graph

f(a) = f(- 4) = 0 ← value from graph

Hence

average rate of change = [tex]\frac{-4-0}{1-(-4)}[/tex] = - [tex]\frac{4}{5}[/tex]

The average rate of change of a function is -4/5 from x=-4 to x=1 function is decreasing.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a graph of a function shown in the picture.

f(-4) = 0

f(1) = -4

Average rate of change of a function = (-4-0)/(1-(-4))

= -4/5

Thus, the average rate of change of a function is -4/5 from x=-4 to x=1 function is decreasing.

In the first one, only D is rising

In the third, only C is increasing

In the last, d is decreasing while C is increasing.

Which only leaves the second option.

Answer: True

Step-by-step explanation:

 We know that the quadratics polynomials have this form:

[tex]f(x)=ax^2+bx+c[/tex]

You need to remember that the degree of a polynomial is given by its highest exponent.

You can observe in the quadratic polynomial [tex]f(x)=ax^2+bx+c[/tex] that the highest exponent is "2", which is the exponent of the term [tex]ax^2[/tex]

Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.

Then, you can say that a quadradic polynomial has degree 2.

2. Those reading finance only is 7.

3. Those who read marketing and finance only is 4.

4. In total, there are 36 students.

Explanation:

To solve this Venn diagram problem involving students reading different subjects, let's take a methodical approach.

Step-by-step Answer:

Gap must be a maximum of 0.005 inches, and uniform all around.  Round out with a sizing tool if necessary.

When brazing, the clearance gap between pipe and fitting should be between 0.002 and 0.006 inches.

This clearance gap is important to allow the brazing material to flow via capillary action and to create a strong, sealed joint. The exact clearance can vary depending on the materials and the application, but staying within this range is a good practice.

For brazing larger diameter pipes and fittings, a slightly larger gap may be acceptable, but generally it is best to maintain the smallest gap that will still allow for proper capillary action of the filler metal.

The exponential function is defined as y = a(1+r)^x, where "a" represents the original account and "r" the rate of growth or decay.

Then we have the following:

1) 22% grow

y = a( 1 + 22%/100 )^x = a(1.22)^x

So the solution is: 124(1.22)^x

2) 12% decay

y = a( 1 - 12%/100 )^x = a(0.88)^x

So the solution is: y = f(x) = 44(0.88)^x

3) 20% decay

y = a( 1 - 20%/100 )^x = a(0.8)^x

So the solution is: f(x) = 22(0.8)

4) 12% Groth

y = a( 1 + 12%/100 )^x = a(1.12)^x

So the solution is: f(x) = 42(1.12)^x

Final answer:

Each exponential function is matched to its percent rate of change by the base of the exponent; a base greater than 1 indicates growth, while a base less than 1 indicates decay.

Explanation:

The question involves matching each exponential function to its corresponding percent rate of change, which indicates whether there is exponential growth or decay. The base of the exponent in the function represents the rate of change: a base greater than 1 indicates growth, while a base less than 1 indicates decay. Here's how we match the given functions:

f(x) = 44[tex](0.88)^x[/tex] corresponds to 12% decay because 0.88 represents a decay rate of 12%.

f(x) = 124[tex](1.22)^x[/tex] corresponds to 22% growth because 1.22 represents a growth rate of 22%.

f(x) = 22[tex](0.8)^x[/tex] corresponds to 20% decay because 0.8 represents a decay rate of 20%.

f(x) = 42[tex](1.12)^x[/tex] corresponds to 12% growth because 1.12 represents a growth rate of 12%.

By recognizing the base of the exponential function, we can determine the percentage rate of change and appropriately classify each function as either exponential growth or decay.
