Explanation:

In an equilateral triangle, all angles and edges are congruent, so with that, you have your answer.

I am joyous to assist you at any time.

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

Answer:

a triangle witih side lengths of 12,16,20

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 speed of the jet is 1302 miles per hour.

Since a private jet can fly 1134.6 miles against a 27-mph headwind in the same amount of time it can fly 1469.4 miles with a 27-mph tailwind, to find the speed of the jet you must perform the following calculation:

Answer: 198cm

Step-by-step explanation:

We are given the dimensions of a rectangular prism;

3cm 9cm and 6cm

We are required to determine its surface area;

We need to know that;

Surface area of a rectangular prism is given by;

A = 2(WL+HL+WH)

Where L, W and H are length , width and height respectively;

Assuming;

Width is 3 cm

Length is 9 cm, and

Height is 6 cm

Then;

Area = 2 ( (3×9) + (6×9) + (3×6))

       = 2(99)

      = 198 cm²

Therefore, the area of the rectangular prism is 198 cm²

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:

i am pretty sure its B..............

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].

Now

Coterminal angle:-

Option C is correct

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

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]

Rearranging the equation and solving for the z-values;

[tex]p(z < 1.8-p < z < -1.4)[/tex]

This becomes
