What is the answer ?

Answer:

2⁹

Step-by-step explanation:

Using the rule of Indices:

aⁿ x aˣ = aⁿ⁺ˣ

Hence: 2²⁺³⁺⁴

= 2⁹

Answer:

9

Step-by-step explanation:

Since it is a multiplication problem you would add all of the exponents up.

2^2 * 2^3 * 2^4

2^(2+3+4)

Given :

A company currently has an advertisement that covers a bill board that is 30 ft wide by 70 ft high. The company wants to reduce the same advertisement to fit on a new billboard that is 25 ft wide by 40 ft high.

To Find :

The dimensions of the largest advertisement that will fix on the billboard without cropping the advertisement.

Solution :

Area of original bill board :

[tex]A_i=30\times 70 = 2100\ ft^2[/tex]

Area of new bill board :

[tex]A_f=25\times 40 = 1000\ ft^2[/tex]

Since, new bill board can be completely fitted in original bill board as its length and breadth both are smaller than that.

So, the dimensions of the largest advertisement that will fix on the billboard without cropping the advertisement is equal to 1000 ft².

Hence, this is the required solution.

Answer:

[tex] \huge \: x = - 5417.33[/tex]

Step-by-step explanation:

[tex]0.75 (x + 200) = 150.5 (2 – 28) \\ [/tex]

Expand the terms and simplify

That's

[tex]0.75x + 150 = 301 - 4214 \\ 0.75x + 150 = - 3913[/tex]

Subtract 150 from both sides of the equation

[tex]0.75x + 150 - 150 = - 3913 - 150 \\ 0.75x = - 4063[/tex]

Divide both sides by 0.75

[tex] \frac{0.75x}{0.75} = - \frac{4063}{0.75} \\ x = - 5417.333333[/tex]

We have the final answer as

Answer:

x = 2

Step-by-step explanation:

-4/5(-8x + 6) = 1 + 7 (distribute first)

6.4x -4.8 = 8 (add 4.8 on both sides)

6.4x = 12.8 (divide by 6.4)

x = 2

PLUG IN

-4/5(-8(2) + 6) = 1 + 7

-4/5(-16 + 6) = 8

-4/5(-10) = 8

8 = 8

Step-by-step explanation:

After all 3 different transformations, the angle measures of the triangle will stay the same, at 45, 45, and 90 degrees.

This is because these 3 transformations do not change the shape of the triangle. They only change the orientation and placement of the triangle.

So, the angle measures will still be 45, 45, and 90 degrees after each transformation.

Yes, the correct answer to this question is Yes.

Answer:

The scale factor is 1/4

Step-by-step explanation:

Here, we are interested in finding the scale factor that helped convert the first point to the second.

Hence, what turned (8,12) to (2,3)

What we shall do here is to simply divide term 2 by term i.e

That would be 2/8 or 3/12 = 1/4

The scale factor was 1/4.

Given that,

The point (8, 12) was dilated to become point (2, 3).

We have to determine,

What was the scale factor?

According to the question,

Scale factors are closely related to the concepts of ratio and proportions.

In ratio and proportions, we multiply or divide a given amount to form a new quantity.

The point (8, 12) was dilated to become point (2, 3).

Therefore,

The scale factor was,

[tex]\rm Scale\ factor = \dfrac{New \ point \ lies \ on \ axis}{Old \ point \ lies \ on \ axis}[/tex]

Substitute the points in the formula for the x-axis,

[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ x-axis}{Old \ point \ lies \ on \ x-axis}\\\\Scale\ factor = \dfrac{2}{8}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]

And substitute the points in the formula for the y-axis,

[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ y-axis}{Old \ point \ lies \ on \ y-axis}\\\\Scale\ factor = \dfrac{3}{12}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]

Hence, The scale factor was 1/4.

After solving (11x-28)=(7x-8) the value of x is 5

Given:

(11x-28) = (7x-8)

11x - 28 - 7x + 8 = 0

(11x - 7x) - 28 + 8 = 0

4x - 28 + 8 = 0

4x - 20 = 0

4x = 20

Dividing by 4 on both sides we get,

4x/4 = 20/4

x = 20/4

x = 5

Therefore after solving (11x-28)=(7x-8) the value of x is 5.

Answer:

I guess that the purchase is at random, then let's see the possible options:

5 diet drinks.

10 regular drinks.

Total drinks = 15

6 bags of fat-free chips

10 bags of regular chips.

Total chips = 16.

Probability of buying at random, a regular drink is equal to the number of regular drinks divided the total number of drinks:

p1 = 5/15 = 1/3

Probability of buying at random a regular bag of chips, we use the same reasoning as before.

p2 = 6/16 = 3/8

The joint probability will be equal to the product of the individual probabilities:

P = p1*p2 = (1/3)*(3/8) = 1/8.

B.The weather pattern in City 2 is more consistent than the weather pattern in City 1

explanation:

Range and interquartile range (IQR) measures the spread of data. Range measure the overall spread and IQR measures spread in 50% of data.

Range is calculated by differencevof maximum and minimum value whereas IQR is calculated by difference of First quartile and third quartile.

Since, the range and IQR is less for City 2 as compared to City 1.

Thus ,weather pattern of City 2 is more consistent as compared to City 1.

Answer:

a)0.976

b)0.00926

c)0.2402

d)0.35

Step-by-step explanation:

Let [tex]X_i[/tex] be an item passed by inspector i

Let Y be the event that there is a fault in an item

The probability that an item has a flaw is 0.1 i.e. P(Y)=0.1

If a flaw is present ,it will be detected by the first inspector with probability 0.92 i.e.[tex]P(\bar{X_1}|Y)=0.92[/tex]

So, [tex]P(X_1|Y)=1-0.92=0.08[/tex]

If a flaw is present ,it will be detected by the second inspector with probability 0.7 i.e.[tex]P(\bar{X_2}|Y)=0.7[/tex]

So,[tex]P(X_2|Y)=1-0.7=0.3[/tex]

If an item does not have a flaw, it will be passed by the first inspector with probability 0.95 i.e. [tex]P(X_1|\bar{Y}) = 0.95[/tex]

So, [tex]P(\bar{X_1}|\bar{Y}) = 1-0.95=0.05[/tex]

If an item does not have a flaw, it will be passed by the second inspector with probability 0.8 i.e. [tex]P(X_2|\bar{Y}) = 0.8[/tex]

So, [tex]P(\bar{X_2}|\bar{Y}) = 1-0.8=0.2[/tex]

a)P(found by atleast one inspector | It has flaw )=1-P(found by none inspector | It has flow )

P(found by atleast one inspector | It has flaw )=[tex]1-P(X_1|Y) P(X_2|Y)[/tex]

P(found by atleast one inspector | It has flaw )=[tex]1-0.08 \times 0.3[/tex]

P(found by atleast one inspector | It has flaw )=0.976

Hence the probability that it will be found by at least one of the two inspectors if it has flaw is 0.976

b)[tex]P(Y|X_1)=\frac{P(X_1|Y) P(Y)}{P(X_1|Y) P(Y)+P(X_1|\bar{Y}) P(\bar{Y})}[/tex]

[tex]P(Y|X_1)=\frac{0.08 \times 0.1}{0.08 \times 0.1+0.95 \times 0.9}=0.00926[/tex]

C)P( two inspectors draw different conclusions on the same item)=[tex]P(X_1 \cap \bar{X_2} \cap Y)+P(\bar{X_1} \cap X_2 \cap Y)+P(X_1 \cap \bar{X_2} \cap \bar{Y})+P(\bar{X_1} \cap X_2 \cap \bar{Y})[/tex]

P( two inspectors draw different conclusions on the same item)=0.2402

D)

[tex]P(Y|(X_1 \cap X_2))=\frac{P(Y \cap X_1 \cap X_2)}{P(X_1 \cap X_2)}\\P(Y|(X_1 \cap X_2))=\frac{P(Y \cap X_1 \cap X_2)}{P(X_1 \cap X_2 \cap Y)+P(X_1 \cap X_2 \cap \bar{Y})}\\P(Y|(X_1 \cap X_2))=0.35[/tex]

Answer:

10 [tex]\frac{1}{8}[/tex] = [tex]\frac{81}{8}[/tex]

Step-by-step explanation:

Given

(m - 10)(8m - 1) = 0

Equate each factor to zero and solve for m

m - 10 = 0 ⇒ m = 10

8m - 1 = 0 ⇒ 8m = 1 ⇒ m = [tex]\frac{1}{8}[/tex]

Thus sum of roots = 10 + [tex]\frac{1}{8}[/tex] = 10 [tex]\frac{1}{8}[/tex] = [tex]\frac{81}{8}[/tex]
