Answer:

The bottom is  11

The median is  12

Step-by-step explanation:

The median is the average of the top and bottom

(13+ 2x-3) /2 = 4x-16

Combine like terms

(10+2x)/2 = 4x-16

Divide by 2

5+x = 4x-16

Subtract x from each side

5+x-x = 4x-16-x

5 = 3x-16

Add 16 to each side

5+16 = 3x-16+16

21 = 3x

Divide by 3

21/3 = 3x/3

7 =x

The bottom is 2x-3 = 2*7-3 = 14-3 = 11

The median is 4x-16 = 4*7-16 = 28 -16 = 12

Answer:

YZ =  12, ML = 11

Step-by-step explanation:

The median is half the sum of the parallel bases, that is

YZ = [tex]\frac{KN+LM}{2}[/tex]

4x - 16 = [tex]\frac{13+2x-3}{2}[/tex] ( multiply both sides by 2 to clear the fraction )

8x - 32 = 10 + 2x ( subtract 2x from both sides )

6x - 32 = 10 ( add 32 to both sides )

6x = 42 ( divide both sides by 6 )

x = 7

Then

YZ = 4x - 16 = 4(7) - 16 = 28 - 16 = 12

ML = 2x - 3 = 2(7) - 3 = 14 - 3 = 11

Answer:

1:3

Step-by-step explanation:

Divide both numbers by the same value to get the ratio

6/6=1

18/6=3

To get the smallest numbers you can get by dividing using the same value

So the ratio would be 1:3

Answer:

He gets 42 visitors 4 weeks after starting to build his website.

He gets 10 new visitors per week.

Step-by-step explanation:

Equation for the number of visitors:

The equation for the number of visitors Timmy's new website receives after t weeks is:

[tex]v(t) = 10t + b[/tex]

In which b is the number of visitors rightly after he starts.

Timmy is building a new website. Right after he starts, he has 2 visitors.

This means that [tex]b = 2[/tex], so:

[tex]v(t) = 10t + 2[/tex]

How many visitors does he get 4 weeks after starting to build his website?

This is v(4). So

[tex]v(4) = 10(4) + 2 = 40 + 2 = 42[/tex]

He gets 42 visitors 4 weeks after starting to build his website.

How any new visitors does he get per week?

After 0 weeks:

[tex]v(0) = 10(0) + 2 = 0 + 2 = 2[/tex]

After 1 week:

[tex]v(1) = 10(1) + 2 = 10 + 2 = 12[/tex]

2 weeks:

After 2 week:

[tex]v(2) = 10(2) + 2 = 20 + 2 = 22[/tex]

22 - 12 = 12 - 2 = 10

He gets 10 new visitors per week.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Then,

(i) Breadth of upper rectangle = 2 units

Length of upper rectangle = 8 - 1 = 7 units

Therefore,

Area of the upper rectangle = 7 × 2 = 14 units2

(ii) Breadth of lower rectangle = 1 unit

Length of lower rectangle = 5 units

Therefore,

Area of the lower rectangle = 5 × 1 = 5 units2

Since,

Area of the figure is = Area of upper rectangle + Area of lower rectangle

= 14 units2 + 5 units2

= 19 units2 (Ans) (4th option)

Answer:

  y = 2(x -2)^2 +1

Step-by-step explanation:

Start by factoring the leading coefficient from the x-terms.

  y = 2(x^2 -4x) +9

Now identify the coefficient of x, -4, and figure half of that: -2. Square this number and add it inside the parentheses. At the same time, subtract the equivalent value outside parentheses. (The leading coefficient must be taken into account.)

  y = 2(x^2 -4x +4) +9 -2(4)

Put in the desired form.

  y = 2(x -2)^2 +1

This matches vertex form ...

  y = a(x -h)^2 +k . . . . . . . . . vertical scale factor 'a'; vertex (h, k)

EXAMPLE:

2/4 simplified is 1/2

1/2 is equal to 0.50

Answer:

[tex]x = 2[/tex]

Step-by-step explanation:

Let's solve:

[tex]4x+22=6(x+3)[/tex]

Step 1: Simplify both sides of the equation.

[tex]4x+22=6(x+3) \\ 4x+22=(6)(x)+(6)(3)\\ (Distribute) \\ 4x+22=6x+18[/tex]

Step 2: Subtract 6x from both sides.

[tex]4x+22−6x=6x+18−6x\\ −2x+22=18[/tex]

Step 3: Subtract 22 from both sides.

[tex]−2x+22−22=18−22 \\ −2x=−4[/tex]

Step 4: Divide both sides by -2.

[tex] \frac{ - 2x}{ - 2} = \frac{ - 4}{ - 2} \\ x=2[/tex]

Answer:

96 km

Step-by-step explanation:

60 / 0.62137 = 96.56064 km

Answer:

No solution

Step-by-step explanation:

Unfortunately your screenshot has cut off the final answer choice, if it says "no solution" you should choose that because these two lines are parallel. Meaning they will never intersect, and the point of intersection is usually the solution.

Answer:

mean

Step-by-step explanation:

1. The mean is always one of the data values. 3. The mode is always one of the data values.

Answer: The mode.

Step-by-step explanation: The answer to this question is the mode, the answer is mode because there might be some numbers that show up the same amount of times like a different number. So there might be TWO modes :’).

Here are the definitions for mean, median, mode, and range:

Mean (the “average”) —> the sum of the numbers in the data set divided by the amount of numbers in the data set.

Median (the “middle”) —> the number in the middle of the data set, when the numbers are placed in numerical order.

Mode (the “most”) —> the number in the data set that shows up the most often.

Range —> the difference between the data set’s largest number and the data set’s smallest number.

Answer:

By the Central Limit Theorem, it is approximately normal with mean 650 and standard deviation 4.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of 650 and a standard deviation of 24.

This means that [tex]\mu = 650, \sigma = 24[/tex].

Sample of 36:

This means that [tex]n = 36, s = \frac{24}{\sqrt{36}} = 4[/tex]

What is the shape of the sampling distribution you would expect to produce?

By the Central Limit Theorem, it is approximately normal with mean 650 and standard deviation 4.
