Answer:

The answer is "35,868,500 people".  

Step-by-step explanation:

In this question, the chance of people that have traveled above 50 miles is calculated. The chance of success is the probability.

[tex]n=50000\\\\ p=15595[/tex]

[tex]\to P(x\geq 50)=\frac{15595}{50000}=0.3119[/tex]

The population of the United States is at 1150000.

Let's determine that portion of the current population has gone more than 50 miles:

[tex]\to E(X)=np,N=115000000,p=0.3119\\\\=0.3119\times 115000000\\\\=35868500[/tex]

Answer:

= -11/4

Step-by-step explanation:

To find the slope given two points

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

   = (6 - -5)/(-2 -2)

   = (6+5)/(-2-2)

    = 11/-4

    = -11/4

Answer:

-2.75 (-2 3/4)

Step-by-step explanation:

you can do rise of a run whenever you have two points so you have 6-(-5)/-2-2 and solve so -11/4 and that equals -2.75.

Answer:

AB ≈ 3.14 in

Step-by-step explanation:

arc AB is calculated as

AB = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{30}{360}[/tex]

     = 2π × 6 × [tex]\frac{1}{12}[/tex]

     = 12π × [tex]\frac{1}{12}[/tex]

     = π ≈ 3.14 in ( to the nearest hundredth )

Answer:

(3,5)

Step-by-step explanation:

For this equation, you need to solve it like simultaneous equations. Both of these have a 4y, so that is relatively easy to do, once you know how to.

The signs in front of the 4y are different, so you add the 2 equations (to remove the ys all together).

This should be (2x+-8x)+(-4y+4y)=(-14+-4), or (2x-8x)+(4y-4y)=(-14-4).

This can be expanded to -6x+0=-18, or -6x=-18.

Dividing both sides by -6 leaves you with x=3.

To find y, substitute this x value into either equation (I picked equation 1 as it is simpler). This gives you 2(3)-4y=-14, expanded to 6-4y=-14.

From there, you subtract the 6 from both sides, to get the y alone (giving -4y=-20).

By dividing both sides by -4, you get y=5.

This means the answer is (3,5).

**This question involves simultaneous equations, so you might want to look at that. I'm always happy to help!

Answer:

3:2

Step-by-step explanation:

The circumference is a distance.  The ratio of the distance is the same as the scale factor.  The ratio of the areas is the ratio of the scale factor squared and the volume is the scale factor cubed.

Answer:

Option 3 and 4.

Step-by-step explanation:

The z score shows by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation[/tex]

Given that mean (μ) = 82, standard deviation (σ) = 5

1) For x = 74:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{74-82}{5} =-1.6[/tex]

Option 1 is incorrect

2) For x < 87

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{87-82}{5} =1[/tex]

From the normal distribution table, P(x < 87) = P(z < 1) = 0.8413 = 84.13%

Option 2 is incorrect

3) For x = 95:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{95-82}{5} =2.6[/tex]

Option 3 is correct

4) For x < 77

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{77-82}{5} =-1[/tex]

From the normal distribution table, P(x < 77) = P(z < -1) = 0.16 = 16%

Option 4 is correct

5) For x > 92

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{92-82}{5} =2[/tex]

From the normal distribution table, P(x > 92) = P(z > 2) = 1 - P(z < -2) = 1 - 0.9772 = 0.0228 = 2.28%

Option 5 is incorrect

Step-by-step explanation:

The given data is :

195, 194, 191, 190, 238, and 192

Mean = (sum of observations)/(total no. of observations)

[tex]\text{Mean}=\dfrac{195+194+191+190+238+192}{6}\\\\=200[/tex]

So, the mean is the best measure. Also, w can find median as follows.

arranging in order : 190,191,192, 194, 195,238

Here, n = 6

[tex]\text{Median}=\dfrac{\dfrac{n}{2}^{th}+(\dfrac{n}{2}+1)^{th}}{2}\\\\\text{Median}=\dfrac{\dfrac{6}{2}^{th}+(\dfrac{6}{2}+1)^{th}}{2}\\\\=\dfrac{3^{th}+4^{th}}{2}\\\\=\dfrac{192+194}{2}\\\\=193[/tex]

Hence, this is the required solution

Answer:

x = 1, y = 1/4

Step-by-step explanation:

Step-by-step explanation:

Given:

Cards labelled 1, 3, 5, 6, 8 and 9.

A card is drawn and not replaced. Then a second card is drawn at random.

To find:

The probability of drawing 2 even numbers.

Solution:

We have,

Even number cards = 6, 8

Odd numbers cards = 1, 3, 5, 9

Total cards =  1, 3, 5, 6, 8 and 9

Number of even cards = 2

Number of total cards = 6

So, the probability of getting an even card in first draw is:

[tex]P_1=\dfrac{\text{Number of even cards}}{\text{Number of total cards}}[/tex]

[tex]P_1=\dfrac{2}{6}[/tex]

[tex]P_1=\dfrac{1}{3}[/tex]

Now,

Number of remaining even cards = 1

Number of remaining cards = 5

So, the probability of getting an even card in second draw is:

[tex]P_2=\dfrac{\text{Number of remaining even cards}}{\text{Number of remaining total cards}}[/tex]

[tex]P_2=\dfrac{1}{5}[/tex]

The probability of drawing 2 even numbers is:

[tex]P=P_1\times P_2[/tex]

[tex]P=\dfrac{1}{3}\times \dfrac{1}{5}[/tex]

[tex]P=\dfrac{1}{15}[/tex]

Therefore, the probability of drawing 2 even numbers is [tex]\dfrac{1}{15}[/tex]. Hence, the correct option is (b).

Answer:

See below.

Step-by-step explanation:

2a. E = 8.25h + 1.2n

2b. E = 8.25 * 3.5 + 1.2 * 10 = $40.88

2c. 8.25 * 8 + 1.2n = 91.2

66 + 1.2n = 91.2
