Solve for the value of each letter.
creativ13 [48]

Answer:

Step-by-step explanation:

1] 6x + 10 = 28  {subtract 10 from both sides}

6x + 10 -10 = 28 - 10

6x = 18  {Divide both sides by 6}

6x/6 = 18/6

x = 3

2]  -2m - 4 = 8 {Add 4 to both side}

 -2m - 4 + 4 = 8 + 4

-2m = 12  {Divide both sides by -2}

-2m/-2 = 12/-2

m = -6

3] x + x + 2x = 48  {add the like terms}

  4x = 48  {divide both sides by 4}

4x/4 = 48/4

x = 12

4] 3y +4 +3y  - 6 = 34 {add the like terms}

   6y - 2 = 34  {Add 2 to both side}

6y - 2 + 2 = 34 +2

6y = 36 {divide both sides by 6}

6y/6 = 36/6

y = 6

5]9(w - 6) = 36 {divide both sides by 9}

[9(w - 6)]/9 = 36/9

w - 6 = 4  {Add 6 to both sides}

w - 6 + 6 = 4 + 6

w = 10

The ages of a group of 135 randomly selected adult females have a standard deviation of 18.3 years. Assume that the ages of fema
NeTakaya

Answer:

Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student is 3625 female statistics student

Step-by-step explanation:

Here, we have

n = \left (\frac{(z_{\alpha/2}) (\sigma) }{E}   \right )^{2}

Where:

n = Required sample size

σ = Standard deviation = 18.3

E = Margin of error = 1/2 year

z_{\alpha /2} = Critical score from the confidence level = 1.645

Therefore,

n = \left (\frac{(1.645) (18.3) }{\frac{1}{2} }   \right )^{2} = 3624.88

Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student = 3625 female statistics student.

What is this please help I need this completed
Arturiano [62]

Answer:

angles 3 and 4 both equal a 90 degree angle or bisect a 90 degree angle.

angle 5 is 44-degrees because it is complementary or vertical to the 44 degree angle.

x=32 because it is on the same line as the 44-degree angle and a line is 180 so 180-44=136 and to get the rest of x you would do the equation backwards so 136 divided by 4 is 34 and 36-2=32

angle a is 136 described above.

angle b, because it is on the same line as the 46 degree angle is 180-46=134

now im pooped :(
