Can someone help me with this?-

Answer:

  8.5 ft

Step-by-step explanation:

We assume that Mr. Simpson can model his construction using a right triangle with leg 7 ft and hypotenuse 11 ft, as shown in the attachment. Then the other leg can be found using the Pythagorean theorem.

__

  a² +b² = c²

  x² +7² = 11²

  x² = 121 -49 = 72

  x = √72 = 6√2 ≈ 8.485 . . . . feet

The slide will be set about 8.5 feet away from the base.

Reason:

Dale is biased toward the two fastest people in the group, but is leaving out the rest of the swimmers who may not be so fast. The people left out may be very distant from the top two swimmers. Therefore, Dale has not picked a representative sample.

As an example with numbers, let's say we had these average speeds in mph: {1, 2, 3, 4, 20, 30}. Of course these are just hypothetical examples and not based on actual realistic speeds; however, the example should still suffice.

That data set shows the average is closer to 2 and 3 than it is to 20 and 30. Dale polling the fastest people greatly skews the mean larger than it should be.

To get a better more representative sample, Dale should randomly pick 2 people regardless if they are the top two swimmers or not. He can pick the names out of a hat, or use a computer program to generate random numbers.

that what I found atleast hope it helps

Answer: x=9

Step-by-step explanation:

Answer:

5x - 6

Step-by-step explanation:

f(x) = 5x + 4

f(x-2) = 5(x -2) + 4

f(x-2) = 5x - 10 + 4

f(x-2) = 5x - 6

I hope this helps!

Answer:

5x - 6

Step-by-step explanation:

Plug in x-2 to the function:

f(x - 2) = 5(x - 2) + 4

= 5x - 10 + 4

= 5x - 6

Answer:

Abdul should have divided by 4, not 6.

Step-by-step explanation:

The first step that we must take before attempting to solve a problem is to understand what the problem statement is asking from us and what is given to us to help accomplish that goal.  Looking at the problem statement, it asks us what the probability of choosing a vegetable is.  We are given information about how many dishes of each type of food there is out of 10 dishes.

The next step that we need to do is to collect the total amount of vegetable dishes that have been listed in the problem statement along with the total amount of dishes.  We know that there are 10 covered dishes and that there are 2 broccoli and 2 carrot which adds up to 4 vegetable dishes.

Now that we have that information we can move onto the final part which is to determine the probability of choosing a vegetable dish.  We can do this by dividing the total amount of vegetable dishes from the total amount of dishes.

Determine the probability

Therefore, looking at the options that best matches the answer that we got we can confidentially say that it is option A, 2/5.

[tex]\huge\text{Hey there!}[/tex]

[tex]\text{Your equation: }\rm{\dfrac{number\ of\ the\ vegetables (the\ carrots\ \& \ the \ broccolis)}{total\ meals\ you\ have\ all\ together} = probability}\\\\\rm{\dfrac{2\ carrots + 2 \ broccolis}{10\ meals} = probability}\\\\\text{2 + 2 = \boxed{\mathbf 4} , right?}\\\\\rm{\dfrac{4}{10} = probability}\\\\\rm{\dfrac{4\div2}{10\div 2} = probability}\\\\\rm{\dfrac{2}{5} = probability}\\\\\\\huge\text{Therefore, your answer should be: \boxed{\mathsf{\dfrac{2}{5}}}}\huge\checkmark[/tex]

Answer:

slope is -5

Step-by-step explanation:

The formula for slope is:

m = (y2 - y1)/(x2 - x1)

m = slope

y2 = y-coordinate of second point

y1 = y-coordinate of first point

x2 = x-coordinate of second point

x1 = x-coordinate of first point

We can choose our first and second points as any points on the table, but we will choose the first andd second points which are (-5,10) and (-3,0).

y2 = 0

y1 = 10

x2 = -3

x1 = -5

m = (0-10)/(-3-(-5))

m = (-10)/(-3+5)

m = (-10)/(2)

m = -5

Answer:

6 square units

Step-by-step explanation:

The area of the base of the triangle is [tex]\sqrt{2^2+2^2}[/tex] which is [tex]2\sqrt{2}[/tex]. The height of the triangle is [tex]\sqrt{3^2+3^2}[/tex] or [tex]3\sqrt{2}[/tex]. The area of the triangle is [tex]\frac{3\sqrt{2} * 2\sqrt{2}}{2}[/tex] which is 6.

Answer:

Assuming you meant 11/5 - √(25/4) The answer is -3/10 or -0.3.

Step-by-step explanation:

Subtract the quantities.

Answer:

x=-5

Step-by-step explanation:

i did 3*x and you get 3x then i did 3*5 and got 15 which now your equation will look like 3x-15=6x then you subtract the 3 with the 6 and you get -15=3x and then you divide the 3 with the -15 and get -5

Hope it helps<33

Answer:

[tex]x = -5[/tex]

Step-by-step explanation:

Step 1:  Distribute

[tex]3(x - 5) = 6x[/tex]

[tex](3 * x) + (3 * -5) = 6x[/tex]

[tex]3x - 15 = 6x[/tex]

Step 2:  Subtract 3x from both sides

[tex]-15 + 3x - 3x = 6x - 3x[/tex]

[tex]-15 = 3x[/tex]

Step 3:  Divide both sides by 3

[tex]-15/3 = 3x/3[/tex]

[tex]-5 = x[/tex]

Answer:  [tex]x = -5[/tex]

Answer: 8.10

Step-by-step explanation: times by each bottle

Answer:

Answer:

It was 88°F hotter in Stockton.

If it was 0°F in New York, Stockton would have been greater by 83°F; as it is -5, add 5 to 83.
As the problem is subtraction, negative.
If the quantity is in negative, like -5, -7, -120; you have to add.
Hope it helps ^_^!

Answer:

yeah it's true

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

It's true that there's 3 ways to write a ratio and those are the 3 ways you can do it.

Answer:

B, C, and E

The reason B, C, and E are the answer's is because the equation of a linear equation is y= mx+b. B, C, and E are written this way. We can eliminate A and D because They are quadratic equations, because the X is squared.

Answer:

9 inches

Step-by-step explanation:

you have to be at least 48 inches so the shortest person that can ride it is 48 and she is 39 so you minus the 39 from 48 and you will get the inches she needs to grow

Answer: The answer to the equation 4,240/8 = 530

Step-by-step explanation:

4,240 divided by 8 = 530

4,000 divided by 8 = 500

4,800 divided by 8 = 600

(For part B 500 would be an underestimate of the answer to 4,240/8 and 600 would be an overestimate of 4,240/8)
