Answer:

? = 3×8/12 = 24/12 = 2

Step-by-step explanation:

Here it is, it is correct.

Answer: (2) /3

Step-by-step explanation:

#1 Way: Solve by a proportion

Let x be the unknown number

Given

8/12=x/3

Cross-multiply

12x=24

x=2

Ans: (2)/3

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

#2 Way: Look at the product between numbers

Given

8/12=?/3

From this, we can see the difference (quotient) between the known value 3 and 12 is 4, meaning 12÷3=4.

Applying the same factor, 8÷4=2

Ans: (2)/3

Answer:

  x = 50

Step-by-step explanation:

The sum of exterior angles of a convex polygon is 360°.

  130° + x° + 30° + 100° + x° = 360°

  2x° = 100° . . . . . . . . . subtract 260° and collect terms

  x = 50 . . . . . . . . divide by 2°

_____

Additional comment

If you reduce each side length to nothing, then you find the angles are measured around a central point. It becomes more clear that their sum is 360°.

Answer: 40 unit²

Step-by-step explanation:

A square pyramid is composed of 1 square and 4 congruent triangles

STEP ONE. Find the area of the square.

A=b²

b=base

A=b²=4²=14

STEP TWO. Find the area of the triangle

A=(1/2)bh

b=base

h=height

A=(1/2)bh

A=(1/2)(4)(3)

A=(1/2)(12)

A=6

There are 4 congruent triangles, so 6×4=24

The surface area of whole=24+16=40 unit²

Answer:

  25 km/h

Step-by-step explanation:

The relation between speed, time, and distance is ...

  speed = distance/time

  distance = speed × time

__

The distance relation is used to find the distance on the first line of the table. The problem statement tells you all of the distances are the same.

The speed relation is used to find the speed on the remaining lines of the table. For the average speed, the total distance and total time are used in the computation.

The average speed is 25 km/h.

Hence, the study would require at least 385 more adult Americans to be sampled as the degree of inaccuracy is E. (e.g., 0.05).

In mathematics, proportionality is the connection between two factors that maintains a fixed ratio called scale factor. Or, to put it another way, if one variable is increased or divided by a specific number, the second variable will also be doubled or divided by that identical number, maintaining their proportionality. Calculus, algebra, and geometry are three areas of mathematics where this idea is frequently applied.

given

(a) If 20% of adult Americans favour the suggested reforms, the sample size needed at the very least is:

n = [(zα/2)² * p * (1-p)] / E²

where z/2 is the standard normal distribution's critical value for the chosen degree of confidence (e.g., 1.96 for a 95% confidence level).

The population proportion is p. (0.2 in this case)

The degree of inaccuracy is E. (e.g., 0.05)

When we enter the values, we obtain:

n = [(1.96)² * 0.2 * (1-0.2)] / 0.05²

n = 1536.64

Thus, the study would require at least 1537 more adult Americans to be sampled.

(b) The minimal sample size needed if the proposed modifications are

supported by 25% of all adult Americans is:

n = [(zα/2)² * p * (1-p)] / E²

where:

The standard normal distribution's critical value, z/2, depends on the desired level of confidence (e.g., 1.96 for a 95% confidence level).

The population proportion is p. (0.25 in this case)

The degree of inaccuracy is E. (e.g., 0.05)

When we enter the values, we obtain:

n = [(1.96)² * 0.25 * (1-0.25)] / 0.05² \sn = 384.16

Hence, the study would require at least 385 more adult Americans to be sampled as the degree of inaccuracy is E. (e.g., 0.05).

Answer:

b = 10

Step-by-step explanation:

P = 2 (l + b)

l = 15

P = 50

Substitute

50 = 2 (15 + b)

multiply

50 = 30 + 2b

subtract

20 = 2b

divide

b = 10

P = 2 (l + b) when l = 15 and P = 50

To find b

P = 2 (l + b) [Given]

Putting the value of P = 50 and l = 15 we get,

50 = 2(15 + b)

[tex] \frac{50}{2} [/tex] = 15 + b

25 = 15 + b

25 - 15 = b

10 = b

So, b = 10

You can try to show this by induction:

• According to the given closed form, we have [tex]S_1=3\times2^{1-1}+2(-1)^1=3-2=1[/tex], which agrees with the initial value S₁ = 1.

• Assume the closed form is correct for all n up to n = k. In particular, we assume

[tex]S_{k-1}=3\times2^{(k-1)-1}+2(-1)^{k-1}=3\times2^{k-2}+2(-1)^{k-1}[/tex]

and

[tex]S_k=3\times2^{k-1}+2(-1)^k[/tex]

We want to then use this assumption to show the closed form is correct for n = k + 1, or

[tex]S_{k+1}=3\times2^{(k+1)-1}+2(-1)^{k+1}=3\times2^k+2(-1)^{k+1}[/tex]

From the given recurrence, we know

[tex]S_{k+1}=S_k+2S_{k-1}[/tex]

so that

[tex]S_{k+1}=3\times2^{k-1}+2(-1)^k + 2\left(3\times2^{k-2}+2(-1)^{k-1}\right)[/tex]

[tex]S_{k+1}=3\times2^{k-1}+2(-1)^k + 3\times2^{k-1}+4(-1)^{k-1}[/tex]

[tex]S_{k+1}=2\times3\times2^{k-1}+(-1)^k\left(2+4(-1)^{-1}\right)[/tex]

[tex]S_{k+1}=3\times2^k-2(-1)^k[/tex]

[tex]S_{k+1}=3\times2^k+2(-1)(-1)^k[/tex]

[tex]\boxed{S_{k+1}=3\times2^k+2(-1)^{k+1}}[/tex]

which is what we needed. QED
