Answer: 13,000 lb

Step-by-step explanation:

6 x 2,000 = 12,000

1/2 * 2,000 = 1,000

12,000 + 1,000 = 13,000

Answer:

--

Step-by-step explanation:

so basically when we write all three of the expressions in one fraction we get the same answer for all three multiplications.

a. (3/4)*7=(3*7)/4

b. 7*(3/4)=(7*3)/4

c. 3*(7/4)=(3*7)/4

when we change the place of the values that are being multiplied the value of the multiplication does not change, that's why they will be have the same answer and when we multiply all the operations, we get the same value as the answer.

Answer:

A. y = -⅓x + 3

Step-by-step explanation:

Find the equation of the graph bin slope-intercept form, y = mx + b. Where,

m = slope = ∆y/∆x

Using two points on the line, (0, 3) and (3, 2),

Slope (m) = (2 - 3)/(3 - 0) = -1/3

m = -⅓

b = y-intercept = 3 (the y-coordinate of the point where the line crosses the y-axis)

✅To write the equation, substitute m = -⅓ and b = 3 into y = mx + b

Thus:

y = -⅓x + 3

Answer:

There is a 40% chance that she will choose a can of beef soup, a 20% chance that she will choose a can of chicken soup, and a combined 60% chance that she will choose a can of beef or chicken soup.

Step-by-step explanation:

Since Ms. Vellejo has 1 can of tomato soup, 4 cans of chicken soup, 3 cans of cheese soup and 2 cans of beef soup in her cabinet, and she will randomly choose one can of soup, to determine what is the probililty that she will choose a can of beef or chicken soup, the following calculation must be performed:

1 + 4 + 3 + 2 = 10

Beef soup = 2 cans = 2/10 = 0.2 = 20%

Chicken soup = 4 cans = 4/10 = 0.4 = 40%

20 + 40 = 60

Thus, there is a 40% chance that she will choose a can of beef soup, a 20% chance that she will choose a can of chicken soup, and a combined 60% chance that she will choose a can of beef or chicken soup.

Answer:

5 lbs

Step-by-step explanation:

90 - 53.10 = 36.90

She spent $36.90 on coffee. Since it cost $7.38 per pound, we can divide the total cost by 7.38 to figure out how many pounds she bought:

36.90 / 7.38 = 5

Raina bought 5 pounds of coffee.

Answer:

1. -12x^8

2. 8x^6

3. 16x^11

Step-by-step explanation:

The required values for the given table are -12x⁸, 8x⁶ and 16x¹¹ respectively. To understand the calculations, check below.

The given table represents the Multiplication table.

To fill the table we need to multiply the corresponding elements of that cell of the table.

For drop-down 1,

[tex](-4x^{11})\times (3x^{-3})=(-4\times 3)x^{11-3}[/tex]

[tex](-4x^{11})\times (3x^{-3})=-12x^{8}[/tex]

For drop-down 2,

[tex](-4x^{11})\times (-2x^{-5})=(-4\times (-2))x^{11-5}[/tex]

[tex](-4x^{11})\times (-2x^{-5})=8x^{6}[/tex]

For drop-down 3,

[tex](-4x^{11})\times (-4)=(-4\times (-4))x^{11}[/tex]

[tex](-4x^{11})\times (-4)=16x^{11}[/tex]

Therefore, the required values are -12x⁸, 8x⁶ and 16x¹¹ respectively.

Answer:

7. [tex]c = 15.81[/tex]

8. [tex]b = 16[/tex]

Step-by-step explanation:

Required

Determine the third sides

(7): We have

[tex]b = 5[/tex]

[tex]a = 15[/tex]

[tex]c=??[/tex]

To find c, we make use of Pythagoras theorem

[tex]c^2 = a^2 + b^2[/tex]

[tex]c^2 = 5^2 + 15^2[/tex]

[tex]c^2 = 250[/tex]

[tex]c = \sqrt{250[/tex]

[tex]c = 15.81[/tex]

(8): We have

[tex]c = 20[/tex]

[tex]a = 12[/tex]

[tex]b = ??[/tex]

To find c, we make use of Pythagoras theorem

[tex]c^2 = a^2 + b^2[/tex]

[tex]20^2 = 12^2 + b^2[/tex]

[tex]400 = 144 + b^2[/tex]

[tex]b^2 = 400 - 144[/tex]

[tex]b^2 = 256[/tex]

[tex]b = \sqrt{256[/tex]

[tex]b = 16[/tex]

Answer:

I. x = -1

II. y = 1

Step-by-step explanation:

Given the following algebraic expressions;

9x + 10y = 1 .......equation 1

9x - 6y = -15 ......equation 2

To solve using the elimination method, we would subtract eqn 1 from eqn 2.

(9x - 9x) + (-6y - 10y) = (-15 - 1)

0x - 16y = -16

-16y = -16

16y = 16

y = 16/16

y = 1

Next, we would find the value of x;

From eqn 1;

9x + 10y = 1

Substituting the value of y, we have;

9x + 10(1) = 1

9x + 10 = 1

9x = 1 - 10

9x = -9

x = -9/9

x = -1

Answer:

Population after 16 year = 927 people (Approx.)

Step-by-step explanation:

Given:

Decrease rate = 10% per year

Current population = 5,000

Find:

Population after 16 year

Computation:

A = P[1-r]ⁿ

A = 5,000[1-0.1]¹⁶

A = 5,000[0.9]¹⁶

A = 5,000[0.1853]

A = 926.51

Population after 16 year = 927 people (Approx.)

Answer:

The answer is "0.0023 and Choice a"

Step-by-step explanation:

In point a:

The central limit theorem:

[tex]\mu_{X}= 250\\\\\sigma_{X}=\frac{\sigma}{\sqrt{n}}=\frac{6}{\sqrt{100}} =0.6\\\\P(\bar{X}>251.7)\\\\=P(z>\frac{251.70-250}{0.6})\\\\=P(z>2.83)\\\\=1-0.9977\\\\=0.0023[/tex]

In point b:

The chance is lower than 0.05. This means that it is very rare to see the average sample above 251.8 if the argument is valid, that is why the means of the sample is far away from the common claimed and casts doubt on the actual mean.

Answer:

We can use ratios for solve this problem

Cross multiply to get:

Lastly, divide both sides by 2 to isolate x

Answer:

Vertical/ x = 25.

Step-by-step explanation:

Vertical angles are self-explanatory; vertical angles are angles that are vertical from each other.

Vertical angles are also congruent (equal), meaning that both angles equal 75°.

4x - 25 = 75.

To solve this expression, we must first add 25 to 75. This is because there is a subtraction sign in front of 25, so we must do the opposite.

25 + 75 = 100

Lastly, divide 100 from 4.

4x = 100

100 / 4 = 25

x = 25

1) Rotation    

2) Reflection

3)Dilation

4) Rotation

5) Reflection

6) Translation

7) Rotation

Step-by-step explanation: :

 Reflection is a flip.

Rotation turns a figure through an angle about a fixed point called the center.

Translation "slides" an object a fixed distance in a given direction.

Dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

Answer:

1. The facts are;

[tex]\overline x _1[/tex] = 95 days

s₁ = 32 days

n₁ = 18 SUV's

[tex]\overline x _2[/tex] = 48 days

n₂ = 38 small cars

s₂  = 24 days

The confidence level = 95%

The confidence interval is (29.55,  64.45)

Step-by-step explanation:

The facts of the problem are;

The number of SUV's he sold, n₁ = 18 SUV's

The average number it took to sell the 18 SUV's, [tex]\overline x _1[/tex] = 95 days

The standard deviation of the time it took to sell the 18 SUV's, s₁ = 32 days

The number of small cars he sold, n₂ = 38 small cars

The average number it took to sell the 38 small cars, [tex]\overline x _2[/tex] = 48 days

The standard deviation of the time it took to sell the 38 small cars, s₂  = 24 days

The 95% confidence interval is given as follows;

Using a graphing calculator, we get, the critical-t, [tex]t_c[/tex] = 2.055529

[tex]\left (\bar{x}_1-\bar{x}_{2} \right ) \pm t_{c} \cdot\sqrt{\dfrac{s _{1}^{2}}{n_{1}}+\dfrac{s _{2}^{2}}{n_{2}}}[/tex]

[tex]\left (95-48 \right ) \pm 2.055529 \times \sqrt{\dfrac{32^{2}}{18}+\dfrac{24^{2}}{38}}[/tex]

We get C.I. = 29.55259 < μ₁ - μ₂ < 64.44741

∴ C.I. ≈ 29.55 < μ₁ - μ₂ < 64.45

Answer:

Step-by-step explanation:

2 x 11=22

22/2=11

Answer:

Yes, it's true

Step-by-step explanation:

A fraction is a part of a whole number for example 1/2. 1/2 is a half of one whole piece and if you multiply it into any whole number whether it's 2,4,6,8,10...... basically, if you multiply a fraction less than one with a non-zero whole number, it will always be less than the whole number it's being cut into smaller pieces. However, if the fraction is greater than 1, we would technically have an answer greater than the whole number product, just something to remember.
