Answer:

[tex]Mean = 20[/tex]

[tex]SD = 2.31[/tex]

Step-by-step explanation:

Given

[tex]a = 16[/tex]

[tex]b = 24[/tex]

Solving (a): The mean

The mean of a uniform distribution is:

[tex]Mean = \frac{1}{2}(a + b)[/tex]

This gives:

[tex]Mean = \frac{1}{2}(16 + 24)[/tex]

[tex]Mean = \frac{1}{2}(40)[/tex]

[tex]Mean = 20[/tex]

Solving (b): The standard deviation

The standard deviation is:

[tex]SD = \sqrt{\frac{(b - a)^2}{12}}[/tex]

This gives:

[tex]SD = \sqrt{\frac{(24 - 16)^2}{12}}[/tex]

[tex]SD = \sqrt{\frac{(8)^2}{12}}[/tex]

[tex]SD = \sqrt{\frac{64}{12}}[/tex]

[tex]SD = \sqrt{5.333}[/tex]

[tex]SD = 2.31[/tex]

Answer:

8.67 dollars per ft squared

Step-by-step explanation:

This is a fraction equal to

130 dollars ÷ 15 ft squared

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 15

130 dollars ÷ 15

15 ft squared ÷ 15

=

8.67 dollars

1 ft squared

=

8.67 dollars

ft squared

= 8.67 dollars per ft squared

Answer:

$8.67

Step-by-step explanation:

you have the the price for 15 square ft

and you are trying to get the price for 1 square ft

just divide the original price by 15

here's the equation format

130 = 15 x

solve for x

Answer:

22.5

Step-by-step explanation:

Set up your proportion. You do 150x15=2,250. 2,250/100=22.5.

Answer:

Correct answers:

$3265$

For this, we can use the formula

A=P0(1+rt).

We know that A=$4,000,r=15%=0.15 and t=1.5, so we can rearrange the formula for A to give

P0=A1+rt,

and substituting the known quantities gives

P0=$4,0001+0.15×1.5=$4,0001.225=$3,265.30..,

which is $3,265 to the nearest dollar.

Answer:

Inequality: [tex]435 + d \geq 815[/tex]

Solution: [tex]d \geq 380[/tex]

Step-by-step explanation:

He has 435 stamps in his collections.

He will collect d stamps, and he wants to collect at least 815 stamps, that is, the sum of 435 and d has to be at least 815.

So the inequality is given by:

[tex]435 + d \geq 815[/tex]

And the answer is given by:

[tex]d \geq 815 - 435[/tex]

[tex]d \geq 380[/tex]

Answer:

It's B.3

Step-by-step explanation:

Substitution. With the equation Y= 9x+28 and Y= 11x+22, you substitute the x-factor with '3'. Which will give you

Y= 9(3)+28         Y= 11(3)+22

Y= 27+28           Y= 33+22

Y= 55                 Y= 55

Let's say we already did the work and found the result of 48*19. That result is 912.

When it comes to multiplying 0.048 and 1.9, we're going to need to do two things to transform those numbers into 48 and 19.

Move the decimal point of 0.048 exactly three spaces to the right. This is the same as multiplying by 1000. So 1000*0.048 = 48

Move the decimal point of 1.9 exactly one space to the right. This is the same as multiplying by 10. So 10*1.9 = 19

Overall, we've multiplied by 1000*10 = 10,000. This means 48*19 = 912 is 10,000 times larger compared to the result of 0.048*1.9

To fix this, we need to divide by 10,000 to get 912/(10,000) = 0.0912

Dividing by 10,000 is the same as moving the decimal point to the left four spaces. Note how 10,000 = 10^4.

I recommend using your calculator to see that 0.048*1.9 = 0.0912 which matches with the previous result we got.

Answer:

14

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

You have to use PEMDAS, so first you do the parentheses, (3+6)=9. Then you multiply 2 times 9=18. The last step is to subtract 4, so 18-4=14

Answer:

In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the Pythagorean equation:[1]

{\displaystyle a^{2}+b^{2}=c^{2},}a^{2}+b^{2}=c^{2},

where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides. The theorem, whose history is the subject of much debate, is named for the Greek thinker Pythagoras, born around 570 BC.

The theorem has been proven numerous times by many different methods—possibly the most for any mathematical theorem. The proofs are diverse, including both geometric proofs and algebraic proofs, with some dating back thousands of years.

The theorem can be generalized in various ways: to higher-dimensional spaces, to spaces that are not Euclidean, to objects that are not right triangles, and to objects that are not triangles at all but n-dimensional solids. The Pythagorean theorem has attracted interest outside mathematics as a symbol of mathematical abstruseness, mystique, or intellectual power; popular references in literature, plays, musicals, songs, stamps, and cartoons abound.-Wikipedia

Step-by-step explanation:

Answer:

d = 1.46 m

Step-by-step explanation:

We'll begin by obtaining the relationship between the force (F) and the distance (d). This can be obtained as follow:

From the question given above,

F is inversely proportional to square of d. This can be written as:

F ∝ 1/d²

F = K/d²

Cross multiply

K = Fd²

But:

Force (F) = 0.006 N

Distance (d) = 4 m

Constant (K) =?

K = Fd²

K = 0.006 × 4²

K = 0.006 × 16

K = 0.096 Nm²

Therefore, the relationship between the force (F) and the distance (d) is:

F = K/d²

F = 0.096 / d²

Finally, we shall determine the distance when the force is 0.045 N. This can be obtained as follow:

Force (F) = 0.045 N

Constant (K) = 0.096 Nm²

Distance (d) =?

F = K/d²

0.045 = 0.096 / d²

Cross multiply

0.045 × d² = 0.096

Divide both side by 0.045

d² = 0.096 / 0.045

Take the square root of both side.

d = √(0.096 / 0.045)

d = 1.46 m.

Answer:

lesser x = -2

greater x = 2

Step-by-step explanation:

The values of a function f(x) are the values of x for which f(x) = 0.

In this question:

[tex]f(x) = 5x^2 - 20[/tex]

So, finding the zeros:

[tex]5x^2 - 20 = 0[/tex]

[tex]5x^2 = 20[/tex]

[tex]x^2 = \frac{20}{5}[/tex]

[tex]x^2 = 4[/tex]

[tex]x = \pm \sqrt{4}[/tex]

[tex]x = \pm 2[/tex]

So

lesser x = -2

greater x = 2

Answer:

it is 112° .. as you will solve it like this (180-44=136) and each angle down there are equal so we will divide 136÷2 so each angle is 68° ,, finally to find x you can do it in two ways 1) (68+44) =112 or you can go with (180-68=112)

2=2

1/2(2)+3=|2|

1+3=2

4=2

1/2(3)+3=|3|

1.5+3=3

4.5=3

1/2(-6)+3=|-6|

-3+3=6

0=6
