Answer:

3 cents

Step-by-step explanation:

First you have to find the price of the 3 pounds of ground beef. Which is 3 • 5.53= 11,06 and then you are going to divide that by 4. Which is 11,06 ÷ 4 = 2,765

Answer:

x = 46

Step-by-step explanation:

64-18=46

Answer:

x=46

Step-by-step explanation:

Subract the 18 from both sides, canceling the 18 from the 'x + 18' and leaving you to subtract 18 from 64, resulting in 46.

Answer:

81[tex]x^{4}[/tex] + 216x³ + 216x² +96x + 16

Step-by-step explanation:

Using the binomial theorem

With coefficients from Pascal's triangle for n = 4

1  4  6  4  1

with decreasing powers of 3x from [tex](3x)^{4}[/tex] to [tex](3x)^{0\\}[/tex]

and increasing powers of 2 from [tex](2)^{0}[/tex] to [tex](2)^{4}[/tex]

Thus

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

= 1[tex](3x)^{4}[/tex][tex](2)^{0}[/tex] + 4[tex](3x)^{3}[/tex][tex](2)^{1}[/tex] + 6(3x)²(2)² + 4[tex](3x)^{1}[/tex][tex](2)^{3}[/tex] + 1[tex](3x)^{0}[/tex][tex](2)^{4}[/tex]

=1.[tex]81x^{4}[/tex].1 + 4.27x³.2 + 6.9x².4 + 4.3x.8 + 1.1.16

= 81[tex]x^{4}[/tex] + 216x³ + 216x²+ 96x + 16

Answer

The answer will be 8⁰

Step-by-step explanation:

Complementary angles always add up to 90⁰ degrees

Answer:

8 degrees (see explanation below)

Step-by-step explanation:

A complimentary angle is when 2 angles are added together to make a 90 degree angle. So if the measure of the current angle is 82, then the other measure is 8.

Answer:

The correct option is D

Step-by-step explanation:

From the question we are told that

   The sample size for male car occupant is  [tex]n_1 = 2450[/tex]

   The number that wear seat belt is [tex]k_1 = \frac{76}{100} * 2450 = 1862[/tex]

   The sample size for female car occupant is [tex]n_2 = 2900[/tex]

   The number that wear a seat belt is   [tex]k_2 = \frac{74}{100} * 2900 = 2146[/tex]

Generally the population proportion is mathematically represented as

       [tex]p = \frac{x_1 + x_2 }{n_1 + n_2 }[/tex]

=>    [tex]p = \frac{1862 + 2146 }{2450 + 2900 }[/tex]

=>  [tex]p = 0.7492[/tex]

The sample proportion for male  car occupant is  

        [tex]\^ p_1 = \frac{k_1}{n_1}[/tex]

=>     [tex]\^ p_1 = \frac{1862}{2450}[/tex]

=>     [tex]\^ p_1 = 0.76[/tex]

The sample proportion for female car occupant is  

        [tex]\^ p_2 = \frac{k_2}{n_2}[/tex]

=>     [tex]\^ p_2 = \frac{2146}{2900}[/tex]

=>     [tex]\^ p_1 = 0.74[/tex]

The null hypothesis is  [tex]H_o : p_1 = p_2[/tex]

The alternative hypothesis is  [tex]H_a : p_1 \ne p_2[/tex]

Generally the standard error is mathematically represented as

        [tex]SE = \sqrt{\frac{p(1 -p )}{ n_1 + n_2} }[/tex]

=>    [tex]SE = \sqrt{\frac{0.7492 (1 -0.7492 )}{ 2450 + 2900} }[/tex]  

=>    [tex]SE = 0.005926[/tex]

Generally the test statistics is mathematically represented as

     [tex]z = \frac{\^ p_1 - \^ p_2}{SE}[/tex]    

=>   [tex]z = \frac{0.76 -0.74}{0.005926}[/tex]

=>   [tex]z = 3.37[/tex]

From the z table  the area under the normal curve to the right  corresponding to  3.37 is  

       [tex]P(Z > 3.37) = 0.00037584[/tex]

Generally the p-value is mathematically represented as

      [tex]p-value = 2 * P(Z > 3.37)= 2* 0.00037584 = 0.0007 5[/tex]

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

The decision rule is  

  Reject the null hypothesis

The conclusion is

 There appears to be a gender gap because there is a significant difference in the proportions

Answer:45.167

Step-by-step explanation:

So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you don't have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167. Hope that Helped! :)

Answer: 64 and 81

Step-by-step explanation: I used my brain. :)

The number 72 lies between the perfect squares  64 and 81 . So, the square root of 72 lies between the numbers  7 and 8 , which means the square root of 72 is  a rational  number.

Answer:

Mean, median, mode is 7 and the range is 4

The value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10

The equation is given as:

[tex]\frac 1x + \frac{1}{x + 18} = \frac{1}{40}[/tex]

Take the LCM

[tex]\frac{x + 18 + x}{x(x + 18)} = \frac{1}{40}[/tex]

This gives

[tex]\frac{2x + 18}{x(x + 18)} = \frac{1}{40}[/tex]

Cross multiply

[tex]40(2x + 18) =x(x + 18)[/tex]

Expand

[tex]80x + 720 =x^2 + 18x[/tex]

Collect like terms

[tex]x^2 + 18x - 80x -720 = 0[/tex]

[tex]x^2 - 62x -720 = 0[/tex]

Using a graphing calculator, we have:

[tex]x = 72\ or\ x =-10[/tex]

The value of x cannot be negative, because of the context.

So, the value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10

Answer:

233.8 Yards

Step-by-step explanation:

Given that,

Length of a rectangular field, l = 227 yards

Breadth of a rectangular field, l = 56 yards

Let x is the distance from one corner of the field to the opposite corner. It can be calculated using Pythagoras theorem,

[tex]x=\sqrt{l^2+b^2} \\\\x=\sqrt{(227)^2+(56)^2} \\\\x=233.8\ \text{Yards}[/tex]

So, the distance from one corner of the field to the opposite corner is 233.8 Yards.
