Step-by-step explanation:

By using exactly four 4s it is possible to write a few numbers: at least from 0 - 30.

=> For example, using exactly four 4s, we can write 1 as follows

1 = 44 / 44

The right hand side of the above equation has exactly four 4s and solving it will give 1.

=>Using exactly four 4s, we can write 2 as follows;

2 = (4/4) + (4/4)

Also, there are exactly four 4s in the right hand side of the above equation and solving it gives 2

=> Using exactly four 4s, we can also write 6 as follows;

6 = 4 x .4 + 4.4

The above equation also contains exactly four 4s which will give 6 when solved. i.e

(4 x .4) + 4.4 = (4 x 0.4) + 4.4 = 6

The expressions for numbers 1 through 10 using exactly four 4s have been tabulated and shown in the image attached to this response.

x = 7.5

y = 1.5

x + y = 9.0  => x = 9 - y

0.50x + 0.20y = 4.05

0.5(9 - y) + 0.2y = 4.05

4.5 - 0.5y + 0.2y = 4.05

4.5 - 4.05 = 0.5y - 0.2y

0.45 = 0.3y

y = 0.45 : 0.3

y = 1.5

x = 9 - 1.5

x = 7.5

Answer: The answer is 3.14 (also known as π)

Step-by-step explanation: The formula for the surface area of a sphere is:

A = 4πr^2

A = 4π (0.5)^2

A = 4π (0.25)

A = (4 x 0.25) π

A = 1π

A = π     or      A = 3.14

Answer:

x = 4

Step-by-step explanation:

6/x + 1/2 = 2

x(6/x + 1/2) = 2*x

x*6/x + x*1/2 = 2x

6 + x/2 = 2x

6 = 2x - x/2

6 = 4x/2 - x/2

6 = 3x/2

6*2/3 = x

12/3 = x

x = 4

probe:

6/4 + 1/2 = 2

3/2 + 1/2 = 4/2

Answer:

Step-by-step explanation:

The solution to the equation 144 = m - 98 is m = 242 as per the PEMDAS rule.

To solve for m in equation 144 = m - 98, we can follow these steps:

Start with the given equation: 144 = m - 98.

To isolate the variable m, we need to eliminate the -98 on the right side of the equation. We can do this by adding 98 to both sides of the equation:

144 + 98 = m - 98 + 98.

Simplifying the equation, we get: 242 = m.

Now we have m = 242 as the solution to the equation.

Therefore, m = 242 is the value that satisfies the equation 144 = m - 98. By substituting m with 242 in the equation, we can verify that it holds true:

144 = 242 - 98.

144 = 144.

Answer:

The percentage of students taking exactly one courses is 38.46%.

Step-by-step explanation:

The frequency distribution table provided for the number of courses taken by part-time students is as follows:

# of Courses      Frequency         Relative            Cumulative

                                                     Frequency          Frequency

________________________________________________

             1                    20                 0.3846                     20

             2                    19                 0.3654                     39

             3                    13                 0.2500                     52

        TOTAL               52                 1.0000

The relative frequency is actually the probability or chance of the particular class or category of a frequency distribution.

The probability of students taking exactly one courses is 0.3846.

Then the percentage of students taking exactly one courses is:

0.3846 × 100% = 38.46%

Thus, the percentage of students taking exactly one courses is 38.46%.

Answer:

32 mph

Step-by-step explanation:

We want to find the patrolman's rate in miles per hour during the shift. Since we want to find miles per hour, we must divide the miles he drove by the number of hours.

rate = miles / hours

He drove 272 miles.

rate = 272 miles / hours

He drove for 8 hours and 30 minutes. There are 60 minutes in 1 hour. One half of 60 is 30. Therefore, we can also say he drove eight and a half, or 8.5 hours.

rate= 272 miles / 8.5 hours

rate = 32 miles / hour

rate= 32 mph

His average rate during the shift was 32 miles per hour.

Answer:

32 mph

Step-by-step explanation:

To answer this, find the average rate of change

Answer:10th term: -27

5th term: - 12

d= -27+12/5

a+(n-1)d=-12

a+(5–1)d=-12

a+4d= -12

a=-12–4d

a=-12-(4×-3)

a=-12+12=0

18  term=a + (18–1)d

=0+(17×-3)

a+9d=-27......(1)

a+4d=-12.....(2)

make a the subject of equation 2 and put into equation 1

-12+4d+9d=-27

-12+13d=-27

d=-15\13

put d into equation 1

a+9(-15/13)=-27

a=16.6

a+17d=x

17+16.6(-15/13)

x=-2 is the 18th term

25÷2(16.6+15.6(-15/13)

Answer:

The table represents a function because each input corresponds to exactly one output.

Step-by-step explanation:

A table can be regarded as representing a function if and only if every input can only be mapped to exactly one output. In other words, it means, only 1 exact output can be assigned to an input. In a table of function, an input cannot have two different outputs. Although, two different inputs can be assigned to the same output.

From the table given, we see that every input has exactly one output. Although, we have different inputs that gives the same output.

Therefore, we can conclude that the table represents a function because each input corresponds to exactly one output.

Answer:

7 cm.

Step-by-step explanation:

Area of the 2 bases = total area - area of curved surface

= 408 - 100 = 308cm^2.

So the area of 1 base = 154 cm^2.

If radius of the base  = r:

pi r^2 = 154

r^2 = 154/pi

r =  sqrt (154/pi)

r = 7.0014 cm

The rate is 16.1% and the base is the final portion with the rate added on to it.

Chance the percentage into a decimal.

16.1% / 100 = 0.161

Multiply.

454 * 0.161 = 73.094

Add.

454 + 73.094 = 527.094 or 527.09

Therefore, the final base is roughly 527.09

Answer:

The percentage is  [tex]P(0.09 < \mu < 1.2 ) = 34.9\%[/tex]

Step-by-step explanation:

From the question we are told that

  The random number is  [tex]x_1 = 0.09 \ and \ x_2 = 1.2[/tex]

Generally the mean of standard normal distribution is  [tex]\mu = 0[/tex]

                 The  standard deviation of a standard normal distribution is  [tex]\sigma = 1[/tex]

The percentage of the data in a standard normal distribution lies between

  [tex]x_1 = 0.09 \ and \ x_2 = 1.2[/tex] is mathematically represented as

       [tex]P(x_1 < \mu < x_2 ) = P(\frac{x_1 - \mu}{\sigma } <\frac{X - \mu}{\sigma } < \frac{x_2 - \mu}{\sigma } )[/tex]

      [tex]P(0.09 < \mu < 1.2 ) = P(\frac{0.09 - 0}{1 } <\frac{X - \mu}{\sigma } < \frac{1.2 - 0}{1 } )[/tex]

      [tex]P(0.09 < \mu < 1.2 ) = P(0.09 <\frac{X - \mu}{\sigma } < 1.2 )[/tex]

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

      [tex]P(0.09 < \mu < 1.2 ) = P(0.09 <Z < 1.2 )[/tex]

      [tex]P(0.09 < \mu < 1.2 ) = P (Z < 1.2 )- P( Z<0.09)[/tex]

From the z-table  

      [tex]P (Z < 1.2 )= 0.88493[/tex]

      [tex]P( Z<0.09) = 0.53586[/tex]

So

    [tex]P(0.09 < \mu < 1.2 ) = 0.88493 - 0.53586[/tex]

    [tex]P(0.09 < \mu < 1.2 ) = 0.349[/tex]

Hence the percentage  is  

     [tex]P(0.09 < \mu < 1.2 ) = 34.9\%[/tex]
