Can some body check my math on this one(question #6) I think it’s n=26 am I right?

Answer:

well the sum of all the fraction combined are 2.05, so you could fill 2 1/2 drawers. So technically you could use 3 drawers, but the 3rd one won't be full.

Answer:

Leta payed $37.50

Step-by-step explanation:

50% is another way of saying half. So half of 100 is 50. She is down to $50.00 If you take another 25% off then it is $37.50. This is because 25% of 50 is 12.50. If you subtract 12.5 from 50 then you get 37.50. This is how I know it is $37.50. Hope this helps! :)

Answer:

1 standard deviation

Step-by-step explanation:

Given that :

IQs as measured by the Wechsler Adult Intelligence Scale are approximately Normal with:

Mean = 100

Standard deviation = 15

About 84% of people will have IQs below 115 because:

84% = 0.84

From z - table, 0.84 corresponds to a z- score of about 0.995

0.995 = 1. 00

The z-score gives the number of standard deviations by which a raw score is above or below the average or mean value.

Raw score = 115

Mean = 100

Standard deviation (sd) = 15

Mean + number of sd's

100 + 1(sd)

100 + 1(15) = 100 + 15 = 115

Answer: (f+g)(5)=37

Step-by-step explanation:

(f+g) (5) is the same as saying f(5)+g(5). Since we are given f(x) and g(x), we can use them to solve. There are two ways to solve. One is to find f(5) and g(5), and then add them together. Another way is to do (f+g)(x), then plug in x=5. I will show both methods.

Method 1

f(5)=4(5)-7                       [multiply]

f(5)=20-7                         [subtract]

f(5)=13

g(5)=3(5)+9                     [multiply]

g(5)=15+9                        [add]

g(5)=24

(f+g)(5)=13+24                [add f(5) and g(5)]

(f+g)(5)=37

--------------------------------------------------------------------------------------------------------

Method 2

(f+g)(x)=4x-7+3x+9         [combine like terms]

(f+g)(x)=7x+2

(f+g)(5)=7(5)+2                [plug in x=5]

(f+g)(5)=35+2                  [add]

(f+g)(5)=37

--------------------------------------------------------------------------------------------------------

Now, we know that (f+g)(5)=37. We confirmed this with both methods.

Hey there!

(7 * 10^5) ÷ (2 * 10^2)

10^5

Answer:

31/55

Step-by-step explanation:

The LCD is 55.

= 31/55

31 is prime, so the fraction cannot be reduced.

Answer: 31/55

Answer:

  D.)  because it cannot be expressed as a ratio of integers

Step-by-step explanation:

The root of any integer that is not a perfect square is irrational. 5 is not a perfect square, so is irrational—it cannot be expressed as the ratio of integers.

__

Proof

Suppose √5 = p/q, where p and q are mutually prime. Then p² = 5q².

If p is even, then q² must be even. We know that √2 is irrational, so the only way for q² to be even is for q to be even—contradicting our requirement on p and q.

If p is odd, then both p² and q² will be odd. We can say p = 2n+1, and q = 2m+1, so we have ...

  p² = 5q²

  (2n+1)² = 5(2m+1)²

  4n² +4n +1 = 20m² +20m +5

  4n² +4n = 4(4m² +4m +1)

  n(n+1) = (2m+1)²

The expression on the left will be even for any integer n; the expression on the right will be odd for any integer m. This equation cannot be satisfied for any integers m and n, so contradicting our assumption √5 = p/q.

We have shown using "proof by contradiction" that √5 cannot be the ratio of integers.

Answer:

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the perpendicular line we must first find the slope of the original line

We must first write the equation in the general form above in order to find the slope

3x + 2y = - 7

2y = - 3x - 7

Divide both sides by 2

y = - 3/2x - 7/2

Comparing with the general equation above

Slope = - 3/2

Since the lines are perpendicular to each other the slope of the perpendicular line is the negative inverse of the original line

Slope of perpendicular line = 2/3

So the equation of the line using point (-8,7) and slope 2/3 is

[tex]y - 7 = \frac{2}{3} (x + 8) \\ y - 7 = \frac{2}{3} x + \frac{16}{3} \\ y = \frac{2}{3} x + \frac{16}{3} + 7[/tex]

We have the final answer as

[tex]y = \frac{2}{3} x + \frac{37}{3} [/tex]

Answer:

a). 85 people

b). 4362 people

Step-by-step explanation:

The given bar graph shows how many people per 100 spelled each word correctly.

a. From the graph given extreme end of the bar for the word "weird" is between 80 - 90.

Therefore, approximate number of the persons who spelled weird correctly will be 85 (rounded to the nearest 5).

b. The number of people who can correctly spelled word "weird" = 85

The number of people who can correctly spelled word "inoculate" = 35

In 100 people, number of people who can correctly spell "weird" more than "inoculate"

= 85 - 35

= 50

in a group of 8724 randomly selected people, number of people who can spell the word "weird" correctly more than "inoculate"

= [tex]\frac{50}{100}\times 8724[/tex]

= 4362 people

Random selection means each individual has equal chance of being selected.

Given graph has the following information:

Total number of people under survey=100

a. To estimate the number of people per 100 who spelled weird correctly

From the graph it is around 84 and rounding it to nearest 5 will results in 85.

b. From the graph,

Number of people can correctly spell inoculate= 35

Number of people can correctly spell weird than inoculate=85-35

=50 out of 100

Using unitary method as follows:

100-------->50

1------------>1/2

8724------>1/2x8724

=4362

Thus, out of  8724 randomly selected​ people, 4362 people can correctly spell weird than inoculate.
