Of the 13,955,000 Asians age 25 and over in the U.S.,8,107,000have completed at least a bachelors degree. What percentage is this?

Answer:

Option C

Step-by-step explanation:

The distributive property states that:

[tex]a(b+c)=ab+ac[/tex]

You have to multiply 'b' and 'c' by 'a' to completely distribute.

Example using Distributive Property:

[tex]4(3+5)\\\\\rightarrow\text{Distribute: }4(3+5)=4(3)+4(5)\\\\4(3+5)=12+20\\\\4(3+5)=32[/tex]

Hope this helps.

Answer:

I'm pretty sure its C.

Step-by-step explanation:

cause a would be distributed into b and c. so

a(b+c)

ab +ac

which will then become ab+ac

Answer:

1. The mean of the data summarized in the given frequency distribution is 51.81 degrees

2. Comparing the computed mean (51.81 degrees) to the actual mean(56.6) degrees, the computed mean is lesser than the actual mean.

Step-by-step explanation:

1) We are given a Frequency distribution.

Mean of a frequency distribution = Fx/F

Where

Fx = Frequency × midpoint

Low Temperature ​(◦​F) Frequency

40−44 2

45−49 7

50−54 9

55−59 6

60−64 2

F =Total Frequency

= 2 + 7 + 9 + 6 + 2

= 26

a)For low temperature 40 - 44

Frequency = 2

Midpoint (x) = 40 +44/2 = 42

Fx =42 × 2 = 84

b) For low temperature 45 - 49

Frequency = 2

Midpoint (x) = 45+49/2 = 47

Fx =47 × 7 = 329

For low temperature 50 - 54

Frequency = 2

Midpoint (x) = 50 + 54/2 = 52

Fx =52 × 9 = 468

For low temperature 55 - 59

Frequency = 6

Midpoint (x) = 55 + 59/2 = 57

Fx =57 × 6 = 342

For low temperature 60 - 64

Frequency = 2

Midpoint (x) = 60 +64/2 = 62

Fx =62 × 2 = 124

Total Fx =84 + 329 + 468 + 342 + 124

= 1347

Mean =Total Fx/ Total Frequency

= 1347/26

= 51.807692308

Approximately = 51.81 degrees

Therefore, mean of the data summarized in the given frequency distribution is 51.81 degrees

2. Comparing the computed mean (51.81 degrees) to the actual mean(56.6) degrees, the computed mean is lesser than the actual mean.

Answer:

10.2% chance

Step-by-step explanation:

There are 12 peaches and 8 bananas for a total of 20 pieces of fruit.

So we can write it:

[tex]\frac{12}{20} * \frac{11}{19} * \frac{10}{18} * \frac{9}{17}[/tex] =  [tex]\frac{11880}{116,280}[/tex] = .102 or 10.2% chance

For ease multiply all numerators (top numbers) together, then multiply the denominators (bottom numbers) together, and then divide.

12 * 11 * 10 * 9 = 11880

20 * 19 * 18 * 17 = 116,280

We start with 12 peaches and 20 total fruit, as we select a peach the number of peaches and total fruit goes down by one. We do this 4 times because you draw 4 fruits. If you select 1 fruit your chances of it being a peach are 12/20, each time you select a fruit the chances of it being a peach go down because you have 1 less total fruit, and 1 less peach. This is why you multiply each probability together.

Answer:

w = 48

w = 196

Step-by-step explanation:

Width = w

Length = l = 4 + 4w

Use the values for length and width above along with the given value for perimeter in the formula for perimeter.

P = 2l + 2w

488 = 2(4 + 4w) + 2w

488 = 8 + 8w + 2w

488 = 8 + 10w

488 - 8 = (8 + 10w) - 8

480 = 10w

(480)/10 = (10w)/10

48 = w

w = 48

The width is 48 yards.  Use this value to solve for length.

l = 4 + 4w

l = 4 + 4(48)

l = 4 + 192

l = 196

The length is 196 yards.

Answer:

6000

Step-by-step explanation:

6 people paid for 5 days= 6000

1 person paid for 1 day= 6000/6

                                    =1000

6 people paid for 12 days= 1000x 12

                                         = 12000

12000- 6000= 6000

Answer:

Option (2)

Step-by-step explanation:

To solve this question we will use the property of tangents drawn to a circle.

"Tangents drawn from an external point to a circle are equal in length"

From the figure attached,

In ΔDEF,

DA = DC = 14 units [Equal tangents]

EA = EB = 13.7 units [Equal tangents]

FB = FC = 9 units [Equal tangents]

Therefore, DE = DA + AE = 14 + 13.7 = 27.7 units

EF = EB + BF = 13.7 + 9 = 22.7 units

DF = DC + FC = 14 + 9 = 23 units

Perimeter of ΔDEF = DE + EF + DF

                               = 27.7 + 22.7 + 23

                               = 73.4 units                            

Option (2) will be the answer.

= 1

Answer:

Step-by-step explanation:

Given the set A = {x | x ∈ N and 20 < x} , from the set it can be seen that the element of the set are natural numbers where  20< x.

If 20< x

reciprocating both sides will change the sense of the inequality

1/20>1/x

cross multiply

x > 20

This means that the values of x are values grater than 20.

The smallest three values will be the smallest three natural numbers greater than 20 and they are 21, 22 and 23. Note that natural numbers are whole numbers.

Answer:

Option (4)

Step-by-step explanation:

D = {x| x is a whole number}

D = {1, 2, 3, 4..........}

E = {x | x is a perfect square between 1 and 9}

E = {4}

F = {x | x is an even number greater than 2 and less than 9}

F = {2, 4, 6, 8}

(E ∩ F) = Set of common numbers of E and F

           = {4}

D ∩ (E ∩ F} = Set of common numbers in the sets of D and (E ∩ F)

                   = {4}

Therefore, Option (4) will be the answer.

Answer:

[tex]\Huge \boxed{y=\frac{3}{4} x+1}[/tex]

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

We can find the slope through two points.

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

m = (4 - -5)/(4 - -8)

m = 9/12 = 3/4

The slope of the line is 3/4.

Slope-intercept form of a line is y=mx+b. Where m is the slope and b is the y-intercept.

y = 3/4x + b

A point on the line is (4, 4). x = 4 and y =4.

4 = 3/4(4) + b

4 = 3 + b

b = 1

The y-intercept is 1.

[tex]\rule[225]{225}{2}[/tex]

Answer:

[tex]\huge\boxed{y = \frac{3}{4}x+1}[/tex]

Step-by-step explanation:

Finding the slope (m) first:

Given the coordinates (-8 , -5) and ( 4 , 4 )

Slope = [tex]\sf \frac{Rise}{Run}[/tex]

Slope = [tex]\sf \frac{y2-y1}{x2-x1}[/tex]

Slope = [tex]\frac{4 + 8}{4+5}[/tex]

Slope = [tex]\frac{12}{9}[/tex]

Slope = m = [tex]\frac{3}{4}[/tex]

Finding y - intercept (b) :

Taking a coordinate say (4,4)

And putting it in slope intercept form along with b

y = mx+b

Where y = 4 , m = 3/4 and x = 4

4 = (3/4)(4) + b

4 = 3+b

4-3 = b

1 = b

So,

b = 1

Putting m and b now in slope-intercept equation:

y = mx+b

[tex]y = \frac{3}{4}x+1[/tex]

Answer:

39 meters

Step-by-step explanation:

We know the bottom distance  ( 20-13) = 7

And we know the height 15-0 =15

We can use the Pythagorean theorem to find the hypotenuse

a^2 + b^2 = c^2

7^2 + 15^2 = c^2

49+225 = c^2

274 = c^2

Taking the square root of each side

sqrt(274) = c

We want the perimeter

a+b+c

7+15+sqrt(274)

22+sqrt(274)

22+16.55294536

38.55294536

Rounding to the nearest meter

39 meters

Answer:

[tex]\huge \boxed{\mathrm{39 \ meters}}[/tex]

Step-by-step explanation:

The perimeter of the right triangle is required.

The base of the triangle is 7 units.

The height of the triangle is 15 units.

The hypotenuse can be found through Pythagorean theorem.

a² + b² = c²

7² + 15² = c²

49 + 225 = c²

274 = c²

c = [tex]\sqrt{274}[/tex]

Adding all the three sides of the right triangle to get the perimeter.

P = a + b + c

P = 7 + 15 + [tex]\sqrt{274}[/tex]

P = 38.552945...

The perimeter of the right triangle is 39 meters rounded to nearest meter.

Answer:

The joint probability distribution of X and Y is shown below.

Step-by-step explanation:

The distributions of X and of Y are described as follows:

    X :    0           1

P (X) : 0.23      0.77

     Y :    1            2          3

P (Y) : 0.40     0.22     0.38

It is provided that X and Y are independent.

That is:

P (X ∩ Y) = P (X) × P (Y)

Compute the joint probability distribution of X and Y as follows:

[tex]P(X=0,Y=1)=P(X=0)\times P(Y=1)=0.23\times 0.40=0.92\\\\P(X=0,Y=2)=P(X=0)\times P(Y=2)=0.23\times 0.22=0.0506\\\\P(X=0,Y=3)=P(X=0)\times P(Y=3)=0.23\times 0.38=0.0874\\\\P(X=1,Y=1)=P(X=1)\times P(Y=1)=0.77\times 0.40=0.308\\\\P(X=1,Y=2)=P(X=1)\times P(Y=2)=0.77\times 0.22=0.1694\\\\P(X=1,Y=3)=P(X=1)\times P(Y=3)=0.77\times 0.38=0.2926[/tex]

      X       0                  1

Y                                              

1           0.9200        0.3080

Answer:

x = 1/2 ; x = -3

Step-by-step explanation:

To solve this problem, we first need the quadratic to be set equal to x.  Then, we can use factoring to solve for the values of x.

2x^2 + 5x = 3

2x^2 + 5x + -3 = 3 + -3

2x^2 + 5x + -3 = 0

Note that the first term's coefficient is 2.  This factors into 1 and 2.

Note that the third term's coefficient is -3.  This factors into 3 and -1.

From here, we will simply create the binomial factors for the quadratic.

(2x - 1) (x + 3) = 0

2x - 1 = 0  ;  x + 3 = 0

2x - 1 + 1 = 0 + 1  ;  x + 3 + -3 = 0 + -3

2x = 1  ;  x = -3

2x * 1/2 = 1 * 1/2  ;  x = -3

x = 1/2  ;  x = -3

So our solutions for this quadratic equation are x = 1/2 or x = -3.

Cheers.

Solution:

2x²+5x=3

Using Factorisation method,

Answer:

Step-by-step explanation:

Area of a triangle is given by

[tex]A = \frac{1}{2} bh[/tex]

where

b is the base

h is the height

From the question

Area = 21 m²

The statement

The height of a triangle is 8 m more than the length of the base is written as

h = 8 + b

Make b the subject

That's

b = h - 8

Substitute the expression into the above formula and solve for the height

That's

[tex]21 = \frac{1}{2} (h - 8)h[/tex]

Multiply through by 2

h² - 8h = 48

h² - 8h - 48 = 0

(h + 4)(h - 12) = 0

h + 4 = 0 h - 12 = 0

h = - 4 h = 12

Since the height cannot be a negative number we have the final answer as

Step-by-step explanation:

                                                   The comparison of two independent population means is very common and provides a way to test the hypothesis that the two groups differ from each other. Is the night shift less productive than the day shift, are the rates of return from fixed asset investments different from those from common stock investments, and so on? An observed difference between two sample means depends on both the means and the sample standard deviations. Very different means can occur by chance if there is great variation among the individual samples. The test statistic will have to account for this fact. The test comparing two independent population means with unknown and possibly unequal population standard deviations is called the Aspin-Welch t-test.

In simple terms, The population standard deviation is a parameter, which is a fixed value calculated from every individual in the population. A sample standard deviation is a statistic. This means that it is calculated from only some of the individuals in a population. Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population

Because: reason:

                                   Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population.
