Divide the difference between 1,200 and 700 by 5

Answer:

2(n + 3) - 6 is the expression that represents the final number.

Step-by-step explanation:

Answer: the expression becomes 2(x +3) - 6.

Let the number be x. Then according to the question,

Step 1 :- Adding 3

=> x + 3

Step 2 :- Multiply the sum by 2

=> 2×(x + 3)

Step 3 :- Subtract 6

=> 2(x +3) - 6

Thus the expression becomes 2(x +3) - 6.

Answer:

D. 2:1 & 6:3

Step-by-step explanation:

Proportion means equal so we need to see which ratios are equal.

To do that we need to make one fo the numbers in the ratio equal the corresponding number in the other ratio, then see if the other matches.

A:

1:2 & 4:2

The second number is already the same but the first isn't, therefore it is not proportional.

B:

1:2 & 6:3

To get 1 to equal 6 we must multiply it by 6, and what you do to one side you must do to the other so we have to multiply 2 by 6 as well

6:12 & 6:3

The first numbers are the same but the second isn't, therefore it is not proportional.

C:

2:1 & 2:4

The first numbers are the same but the second isn't, therefore it is not proportional

D:

2:1 & 6:3

to get 2 to equal 6 we need to multiply it by 3, which means we have to multiu 1 by 3 too

6:3 & 6:3

These are equal so this is proportional.

Answer:

Step-by-step explanation:

27370 - 26986.82 = 383.18ft

0.2% = 0.2/100 = 0.002

27370*0.002 = 54.74

each year the montain reduce your elevation

Answer:

they cost the same after 2 months

Step-by-step explanation:

Since we're looking for these two gyms cost the same, we need to make the equation compare the two together:

35x + 80 = 75x (the 1st gym with a joining fee $80 and 35 monthly equals $75 monthly)

Subtract 35x from both sides:

35x - 35x + 80 = 75x - 35x

80 = 40x

Divide by 40:

80 / 40 = 40x / 40

2 = x

So they cost the same after 2 months

35 * 2 + 80 = 75 * 2

150 = 150

And you'll be spending $150 in total.

a) We can write 23,50,000,000 as 2350 million in standard form.

b) 25,000,000. c) The number 9 × 10⁴ is a square number.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

a) We have to write 2350 million in standard form.

⇒ 23,50,000,000

b) We have to write 25 × 10⁶ in standard form.

⇒ 25,000,000

c)

A. 4 × 10⁵  = 4,00,000

B. 9 × 10⁴ = 90,000 = 3² × (10²)²

This number is a square number.

C. 4 × 10³ = 4,000

D. 9 × 10³ = 9,000

Complete Question

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 143 millimetres, and a standard deviation of 5. If a random sample of 47 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 0.2 millimetres? Round your answer to four decimal places.

Answer:

The probability is [tex]P(|\= x - \mu | \ge 0.2 ) = 0.78394[/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  47

    The mean diameter is [tex]\mu = 143[/tex]

    The standard deviation is [tex]\sigma = 5[/tex]

Generally the standard error of the mean is mathematically represented as

       [tex]\sigma_{x} = \frac{\sigma }{\sqrt{n} }[/tex]

=>     [tex]\sigma_{x} = \frac{5 }{\sqrt{47} }[/tex]

=>     [tex]\sigma_{x} = 0.7293[/tex]

Generally the probability that the sample mean will differ from the population mean by more than 0.2 milli meters is mathematically represented as

       [tex]P(|\= x - \mu | \ge 0.2 ) = P(\frac{|\= x - \mu|}{\sigma_{x}} \ge \frac{0.2}{0.7293} )[/tex]

[tex]\frac{|\= x - \mu | -\mu}{\sigma }  =  |Z| (The  \ standardized \  value\  of  \ {|\= x - \mu |  )[/tex]

=>      [tex]P(|\= x - \mu | \ge 0.2 ) = P(|Z| \ge 0.2742 )[/tex]

=>     [tex]P(|\= x - \mu | \ge 0.2 ) = P(Z < - 2742) + P(Z > 0.2742)[/tex]

From the z table  the area under the normal curve to the left corresponding to   -2.742  is

    [tex]P(Z < -0.2742) =0.39197[/tex]

From the z table  the area under the normal curve to the right corresponding to   2.742  is        

    P(Z > 0.2742)   =  0.39197

So

      [tex]P(|\= x - \mu | \ge 0.2 ) = 0.39197 + 0.39197[/tex]

      [tex]P(|\= x - \mu | \ge 0.2 ) = 0.78394[/tex]

Answer:

16.86 ft/s

Step-by-step explanation:

Given that

Speed of the carousel, s = 14 rpm

Distance from the carousel, d = 23 ft

To start with, we convert the given speed to revolution per second, so that

s = 14/60 rev/sec

To find the needed speed, we use the formula

v =2πnR, remember that Diameter = 2R, so we substitute D for 2R and get πnD

v = πnD, and we use this to find our needed velocity

v = 3.142 * 14/60 * 23

v = 72.266 * 14/60

v = 16.86 ft/s

Therefore the boy must run at a speed of 16.86 ft/s in order to be able to match the carousel and jump on it
