Answer:

4. 72 m

5. 42 m

6. 66 yd

8. 18 yd

9. 200 cm

Step-by-step explanation:

3) 1 × 3 × 8 + [5 × 8 × (4-3)] = 24 + 40 = 64 yd³

4) 9 × 1 × 8 = 72 m³

5) 3 × 7 × 2 = 42 m³

6) 3 × 3 × (6 - 2) + 2 × 5 × 3 = 36 + 30 = 66 yd³

7) (7 - 5) × 7 × 3 + 8 × 7 × 5 = 42 + 280 = 322 mm³

8) 3 × 3 × 2 = 18 yd³

9) 8 × 5 × 5 = 200 cm³

Step-by-step explanation:

Answer:

lateral area is  329.7 and the surface area is 483.56

Step-by-step explanation:

Lateral area = [tex]\pi (7)(15) = 105\pi = 329.7\\[/tex]

Surface area = lateral area + base area

Base area= [tex]\pi r^{2}[/tex] = [tex]\pi (7)^{2}[/tex] = [tex]49\pi[/tex]

Surface area = 105[tex]\pi + 49\pi = 154\pi = 483.56[/tex]

Answer:

29 / 5 = 5.8

Step-by-step explanation:

To round a mixed number to the nearest whole number, simply look at the fraction part.

If the fraction is more than one half, round up.

If this fraction is less than one half, round down.

In the number 29 1/5, 1/5 is LESS than one half, so we round down.

In the number 4 6/7, is 6/7 is MORE than one half, so we round up.

29 1/5 rounded to the nearest whole number is 29.

4 6/7 rounded to the nearest whole number is 7.

And, 29/7 = 5.8

Therefore, the estimated quotient is 5.8.

Answer:

No, it is not.

Step-by-step explanation:

1/5 is equal to 0.2

5/1 is equal to 5 because there are 5 ones.

Answer:

$ ( 3 x  + 75000 / x )

Step-by-step explanation:

Function that models the total inventory cost as a function of x

holding cost = $6

ordering cost ( fixed cost ) = $30

cost of a pair = $6

Total demand = 2500

∴The total inventory cost ( TIC ) is represented as

holding cost + Ordering cost

= 1 / 2 ( x ) ($6 )  + 2500 / x  ( $30 )

= $ ( 3 x  + 75000 / x )

while total cost  = $ ( 3x + 75000 /x + ( 2500 * 6 ) )

Step-by-step explanation:

Answer:

By the Central Limit Theorem, it is approximately normal with mean 0.29 and standard deviation 0.0596

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

According to the U.S. Census Bureau, 29% of Americans age 25 years or older have already earned a bachelor's or more advanced degree.

This means that [tex]p = 0.29[/tex]

You decide to randomly select 58 adults over the age of 25 to ask if they have earned at least a bachelor's degree.

This means that [tex]n = 58[/tex]

Describe the sampling distribution of the proportion of respondents who have earned at least a bachelor's degree.

By the Central Limit Theorem, it is approximately normal with mean [tex]\mu = p = 0.29[/tex] and the standard deviation is [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.29*0.71}{58}} = 0.0596[/tex]

Answer:

Step-by-step explanation:

Simplifying

5(2x + -6) + 20 = 10

Reorder the terms:

5(-6 + 2x) + 20 = 10

(-6 * 5 + 2x * 5) + 20 = 10

(-30 + 10x) + 20 = 10

Reorder the terms:

-30 + 20 + 10x = 10

Combine like terms: -30 + 20 = -10

-10 + 10x = 10

Solving

-10 + 10x = 10

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10' to each side of the equation.

-10 + 10 + 10x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 10x = 10 + 10

10x = 10 + 10

Combine like terms: 10 + 10 = 20

10x = 20

Divide each side by '10'.

x = 2

Simplifying

x = 2

Answer:

x=2

Step-by-step explanation:

Let's solve your equation step-by-step.

5(2x−6)+20=10

Step 1: Simplify both sides of the equation.

5(2x−6)+20=10

(5)(2x)+(5)(−6)+20=10(Distribute)

10x+−30+20=10

(10x)+(−30+20)=10(Combine Like Terms)

10x+−10=10

10x−10=10

Step 2: Add 10 to both sides.

10x−10+10=10+10

10x=20

Step 3: Divide both sides by 10.

10x

10

Answer:

[tex]\frac{x^{2} + 19x + 102}{4(x + 5)(x + 7)}[/tex]

Step-by-step explanation:

I have factored and multiplied lwh to get the volumes

Vol. = [tex]\frac{2x - 1}{(2x - 3)(x + 5)}[/tex] [tex]\frac{2(2x - 3)}{3x - 1}[/tex][tex]\frac{(3x - 1)(x + 3)}{(2x - 1)(x + 3)}[/tex] + [tex]\frac{x - 5}{3x + 2}[/tex][tex]\frac{3x + 2}{4}[/tex][tex]\frac{x - 2}{(x + 7)(x - 5)}[/tex]

      = [tex]\frac{4}{x + 5}[/tex] + [tex]\frac{x - 2}{4(x + 7)}[/tex]

      = [tex]\frac{4(4)(x + 7) + (x - 2)(x + 5)}{4(x + 5)(x + 7)}[/tex]

      =  [tex]\frac{16x + 112 + x^{2} + 3x -10}{4(x + 5)(x + 7)}[/tex]

      = [tex]\frac{x^{2} + 19x + 102}{4(x + 5)(x + 7)}[/tex]

If I have done everything correctly, then [tex]\frac{x^{2} + 19x + 102}{4(x + 5)(x + 7)}[/tex] is the total volume

This a real exercise in factoring and multiplying and adding fractions

So i was literally over here trying to big brain this problem, literally stressing like "Oh my gosh why is this so difficult wth is going on rn?!" when all i had to do was find the equation(which has been sitting on my paper for the last 15 minutes) and plug it in.

-_-

Chile anyways so the equation to the problem is 3(x+5) =20. And all you have to do is split the (x+5) into three parts on the tape diagram and it would all equal 20.

Answer:

(a) [tex]Pr = 0.3024[/tex]

(b) [tex]Pr = 0.6976[/tex]

(c) [tex]Pr = \frac{^9P_{n-1}}{10^{n-1}}[/tex]

Step-by-step explanation:

Given

[tex]Start = \{5,6,7,8\}[/tex] i.e. between 4 and 9

[tex]n(Start) =4[/tex]

[tex]Digits = 5[/tex]

Solving (a): Probability that each of the 5 digit are different

Since there is no restriction;

The total possible selection is as follows:

[tex]First\ digit = 4[/tex] (i.e. any of the 4 start digits)

[tex]Second\ digit = 10\\[/tex] (i.e. any of the 10 digits 0 - 9)

[tex]Third\ digit = 10[/tex] (i.e. any of the 10 digits 0 - 9)

[tex]Fourth\ digit = 10[/tex] (i.e. any of the 10 digits 0 - 9)

[tex]Fifth\ digit = 10[/tex] (i.e. any of the 10 digits 0 - 9)

So, the total is:

[tex]Total = 4 * 10 * 10 * 10 * 10[/tex]

[tex]Total = 40000[/tex]

For selection that all digits are different, the selection is:

[tex]First\ digit = 4[/tex] (i.e. any of the 4 start digits)

[tex]Second\ digit = 9[/tex] (i.e. any of the remaining 9)

[tex]Third\ digit = 8[/tex] (i.e. any of the remaining 8)

[tex]Fourth\ digit = 7[/tex] (i.e. any of the remaining 7)

[tex]Fifth\ digit = 6[/tex] (i.e. any of the remaining 6)

So:

[tex]Selection =4 * 9 * 8 * 7 * 6[/tex]

[tex]Selection =12096[/tex]

So, the probability is:

[tex]Pr = \frac{Selection}{Total}[/tex]

[tex]Pr = \frac{12096}{40000}[/tex]

[tex]Pr = 0.3024[/tex]

Solving (b): At least 1 repeated digit

The probability calculated in (a) is the all digits are different i.e. P(None)

So, using laws of complement

We have:

[tex]P(At\ least\ 1) = 1 - P(None)[/tex]

So, we have:

[tex]Pr= 1 - 0.3024[/tex]

[tex]Pr = 0.6976[/tex]

Solving (c): An expression to model the probability.

Using (a) as a point of reference, we have;

[tex]Pr = \frac{Selection}{Total}[/tex]

Where

[tex]Selection =4 * 9 * 8 * 7 * 6[/tex] ---- for selection of 5 i.e. n = 5

[tex]Total = 4 * 10 * 10 * 10 * 10[/tex]

[tex]Selection =4 * 9 * 8 * 7 * 6[/tex]

This can be rewritten as:

[tex]Selection = 4 * ^9P_4[/tex]

4 can be expressed as: 5 - 1

So, we have:

[tex]Selection = (5-1) *^9P_{5-1}[/tex]

Substitute n for 5

[tex]Selection = (n-1) *^9P_{n-1}[/tex]

[tex]Selection = (n-1)^9P_{n-1}[/tex]

[tex]Total = 4 * 10 * 10 * 10 * 10[/tex]

This can be rewritten as:

[tex]Total = 4 * 10^4[/tex]

[tex]Total = (5-1) * 10^{5-1}[/tex]

[tex]Total = (n-1) * 10^{n-1}[/tex]

[tex]Total = (n-1) 10^{n-1}[/tex]

So, the expression is:

[tex]Pr = \frac{(n-1)^9P_{n-1}}{(n-1)10^{n-1}}[/tex]

[tex]Pr = \frac{^9P_{n-1}}{10^{n-1}}[/tex]

Where n represents the digit number
