This word problem is another way of saying

How many times can 6/14 go into 49/14

To find this out we divide

(49/14)/(6/14)

We also know that dividing by a fraction is the same as multiplying

=(49/14)(14/6)

=49/6

≈8.16

As we just want how many segments of 6/14 feet rope, we can ignore the decimals/round down getting the answer

Eight pieces of rope can be made our of 49/14 piece of rope.

Answer:

$13.23

Step-by-step explanation:

first, you divide 6 by $11.34 then you multiply 7 by $1.89 to get 13.23.

Answer:

y/2 = 9

In order to find the value of y, we must first isolate y by performing inverse operations.

Right now, y is being divided by 2, so the inverse operation of division is multiplication.

So we multiply by 2 on both sides:

y/2 = 9

*2     *2

2/2y = 18

y = 18

Answer: 346.2yd³

Step-by-step explanation:

Volume = Area of Base x Height

Volume = πr² x 9

Volume = π(3.5)² x 9

Volume = 38.465 x 9

Volume = 346.184 ≅ 346.2yd³

The selection of the basketball players is an illustration of combination

The number of ways the basketball players can be chosen is  78

The given parameters are:

Number of players (n) =13

Players to select (r) = 2

The number of ways the players can be selected is calculated as:

[tex]^nC_r = \frac{n!}{(n -r)!r!}[/tex]

The equation becomes

[tex]^{13}C_2 = \frac{13!}{(13 -2)!2!}[/tex]

Evaluate the difference

[tex]^{13}C_2 = \frac{13!}{11!2!}[/tex]

Evaluate the factorials

[tex]^{13}C_2 = \frac{13 * 12 * 11!}{11! * 2}[/tex]

Evaluate the quotient

[tex]^{13}C_2 = 13 * 6[/tex]

Evaluate the product

[tex]^{13}C_2 = 78[/tex]

Hence, the number of ways the basketball players can be chosen is  78

The probability of randomly selecting a can between 205cm to 210cm is 0.8765

Data;

To solve this problem, we can simply use the formula of probability and substitute the value.

[tex]p\frac{(205-108.5)}{2..5} < \frac{x - 208.5}{2.5} < \frac{210 - 205.5}{2.5}\\p(-1.4 < z < 1.8)[/tex]

Answer:

The base is 14 and the height is 8

Step-by-step explanation:

8 times 14 is 112. 112 divided by 2 is 56.

Answer:

First step : State the null and the alternative hypothesis

   The null hypothesis is  [tex]H_o : \mu = 3.5 \ hours[/tex]

    The alternative hypothesis is  [tex]H_a : \mu > 3.5 \ hours[/tex]

Second Step : Calculate the test statistics

   Generally the test statistics is mathematically represented as

             [tex]z = \frac{\= x - \mu }{\frac{\sigma }{\sqrt{n} } }[/tex]

=>           [tex]z = \frac{3.75 - 3.5 }{\frac{0.7 }{\sqrt{45} } }[/tex]

=>           [tex]z  =  2.11[/tex]

Third Step  : Obtain the p-value

Generally from the z-table the probability of  z  =  2.11 is

    [tex] P(Z  >  2.11) =  0.0174[/tex]

Fourth Step : Compare the p-value with the level of significance and state the decision rule and the conclusion

From the obtained value  the [tex]p-value  <  \alpha[/tex] hence

 The decision rule is  

The null hypothesis is rejected

 The conclusion is

There is sufficient evidence to conclude that average of the laptop batteries is more than 3.5 hours of use per charge

Step-by-step explanation:

From the question we are told that

  The population mean is [tex]\mu = 3.5 \ hours[/tex]

   The sample size is  n =  45

   The standard deviation is  [tex]\sigma = 0.7 \ hours[/tex]

   The sample mean is  [tex]\= x = 3.75[/tex]

    The level of significance is  [tex]\alpha = 0.05[/tex]

First step : State the null and the alternative hypothesis

   The null hypothesis is  [tex]H_o : \mu = 3.5 \ hours[/tex]

    The alternative hypothesis is  [tex]H_a : \mu > 3.5 \ hours[/tex]

Second Step : Calculate the test statistics

   Generally the test statistics is mathematically represented as

             [tex]z = \frac{\= x - \mu }{\frac{\sigma }{\sqrt{n} } }[/tex]

=>           [tex]z = \frac{3.75 - 3.5 }{\frac{0.7 }{\sqrt{45} } }[/tex]

=>           [tex]z  =  2.11[/tex]

Third Step  : Obtain the p-value

Generally from the z-table the probability of  z  =  2.11 is

    [tex] P(Z  >  2.11) =  0.0174[/tex]

Fourth Step : Compare the p-value with the level of significance and state the decision rule and the conclusion

From the obtained value  the [tex]p-value  <  \alpha[/tex] hence

 The decision rule is

 The conclusion is

There is sufficient evidence to conclude that average of the laptop batteries is more than 3.5 hours of use per charge

To solve linear equations, we must perform inverse operations on both sides of the equal sign to cancel values out.

We perform inverse operations to combine like terms. This means to get x to one side and everything else on the other.

[tex]5x+7=15[/tex]

Because 7 is being added to x, subtract it from both sides:

[tex]5x+7-7=15-7\\5x=8[/tex]

Because x is being multiplied by 5, divide both sides by 5:

[tex]\dfrac{5x}{5}=\dfrac{8}{5}\\\\x=\dfrac{8}{5}[/tex]

Therefore. [tex]x=\dfrac{8}{5}[/tex].

[tex]7x+4=5x-18[/tex]

Here, we can group all the x values on the left side of the equation. Subtract 5x from both sides:

[tex]7x+4-5x=5x-18-5x\\2x+4=-18[/tex]

To isolate x, subtract 4 from both sides:

[tex]2x+4-4=-18-4\\2x=-22[/tex]

Divide both sides by 2:

[tex]\dfrac{2x}{2}=\dfrac{-22}{2}\\\\x=-11[/tex]

Therefore, [tex]x=-11[/tex].

[tex] ln({x}^{3} - 4x) - ln(x {}^{2} - 2x ) [/tex]

can be written as;

[tex] ln( \frac{ {x}^{3} - 4x }{ {x}^2 - 2x } ) [/tex]

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

Now all you have to do, is divide the numerator and denominator by x and by (x-2)

to get,

[tex] ln( \frac{x(x - 2)(x + 2)}{x(x - 2)} ) = ln( \frac{x + 2}{1} ) = ln(x + 2) [/tex]

We proved that ln(x³-4x)-ln(x²-2) is equal to ln(x+2) :)
