The term that describes variables that represent the characteristics or attributes of participants and cannot be manipulated is called "non-manipulated variables" or "non-experimental variables".

These variables are typically measured or observed as they naturally exist and are not intentionally changed or controlled by the researcher. Non-manipulated variables are often used in observational studies or correlational research designs where the focus is on examining relationships or associations between variables rather than establishing cause-and-effect relationships through experimental manipulation.

Step-by-step explanation:

The quotient in terms of the two fractions

Determine 2/3 foot that can be gotten from 5 1/3

Divide  5 1/3  by 2/3  ( how to get quotient )

= 5 1/3 / 2/3

= (16 / 3 ) / ( 2/3 )  ( meaning of the quotient )

Answer:

if two Angles have equal measure then the slide opposite to them equal in the length is 6 units

The trigonometric form of the complex number z = -1 - i is z = √2cis(3π/4) and the roots of √z are √2/2cis(3π/8) and √2/2cis(11π/8).

a) Trigonometric form of the complex number z = -1 - i is given by:

r = |z| = √(1²+1²) = √2θ = arctan(-1/-1) + π = 3π/4

Therefore, z = √2cis(3π/4)b)

Since, √z = (√2cis(3π/4))/2

= (√2/2)(cis(3π/4)/2), the roots of √z are given by:

√2/2cis(3π/4 + 2nπ)/2, where n = 0, 1.

Therefore, the roots are √2/2cis(3π/8) and √2/2cis(11π/8) and they are plotted as shown below:

 In summary, the trigonometric form of the complex number z = -1 - i is z = √2cis(3π/4) and the roots of √z are √2/2cis(3π/8) and √2/2cis(11π/8).

After considering all the given data we conclude that approximate percentage of area under the curve is 10.6%, which is approximately 0.106 as a decimal or 53/500 as a fraction

In  case of standard normal distribution, the area under the curve less than 1.25 is 0.894.
Then the standard normal distribution is symmetric about the mean, the area under the curve less than -1.25 is the same as the area under the curve greater than 1.25.
Hence, the approximate percentage of the area under the curve less than -1.25 is approximately
(1 - 0.894) * 100% = 10.6%,

Answer:

8x+5005073

Step-by-step explanation:

Answer:

Step-by-step explanation:

The formula to approach this shall be:

( Final price - Initial price )/ Final price × 100/1 ............. 1

Hence for the snow shovels

Initial price = $241.50 for 7

Each will cost = $241.50/7

= $34.5

Final price for snow shovels

= $105.57 for 3 shovels

Each will cost = $105.57/3

= $35.19

Now considering the bags of salt

Initial price = $6.20 each

Final price = $39.06 for 6 bags

Each bag cost = $39.06/6

= $6.51

Now apply the formula in equation (1)

For snow shovels

($35.19- $34.5)/$34.5 × 100/1

= 0.69/34.5 × 100/1

= 0.02×100/1

= 2%

For bags of salt

($6.51-$6.20)/$6.20 ×100/1

0.31/6.20×100/1

0.05×100/1

= 5%

Hence from the above solution, we can now deduce that shovel increased by 2% while bags of salt went up by 5%.

Answer:

∠ W = 51°

Step-by-step explanation:

Since WX is the diameter , then

∠ WYX = 90° ( angle in a semicircle )

The sum of the 3 angles in a triangle = 180° , then

x + x + 12 + 90 = 180

2x + 102 = 180 ( subtract 102 from both sides )

2x = 78 ( divide both sides by 2 )

x = 39

Then

∠ W = x + 12 = 39 + 12 = 51°

The predicted value of y when x = 15 is given as follows:

15.8.

To find the regression equation, which is also called called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.

The points in this problem are given as follows:

(12, 18), (9, 35), (14, 12), (8, 40), (10, 31), (4, 33), (18,10).

Inserting these points into the calculator, the line of best fit is given as follows:

y = -2.28x + 50.

When the value of y when x = 15 is given as follows:

y = -2.28(15) + 50

y = 15.8.
