Answer:

a) drinking caffeinated coffee

b) hyperactivity

c) experimental study

d) Non-Probability Sampling Method

Explanation:

a) An independent variable refers to the object(s) or variable that is been measured which is not affected or changed by other variables. Rather, the independent variable affects or changes other variables. That is why drinking caffeinated coffee falls under the independent variable.

b) The dependent variable on other hand is a variable that can be affected or changed by the independent variable. That is why hyperactivity falls under the dependent variable.

c) Noteworthy is the fact that in an experimental study a researcher usually alters the level of the independent variable [the caffeinated coffee]. This is evident in this case because we are told, "One group received regular coffee and the other received decaffeinated coffee."

d) The kind of sampling method used is the Non-Probability Sampling Method because they [the students] which formed the population were not randomly selected, but "intentionally balanced" into groups by the student’s year, major, and gender.

JK + KL = JL

(4x + 3) + (9x + 5) = 47

4x + 9x = 47 - 3 - 5

13x = 39

x = 39 / 13

x = 3

Answer:

-1

Step-by-step explanation:

I simplified the expression using the definition of an imaginary number i=√1

First I applied the exponent rule: [tex]a^{bc}=\left(a^b\right)^c[/tex]

[tex]i^{82} = \left(i^2\right)^{41}[/tex]

[tex]=\left(i^2\right)^{41}[/tex]

Then, I applied the maginary number rule: [tex]\:i^2=-1[/tex]

[tex]=\left(-1\right)^{41}[/tex]

Then I used the exponent rule again: [tex]\left(-a\right)^n=-a^n,\:\mathrm{if\:}n\mathrm{\:is\:odd}[/tex]

[tex]\left(-1\right)^{41}=-1^{41}[/tex]

[tex]=-1^{41}[/tex]

Sooo, [tex]1^{41}=1,[/tex] which equals =-1.

Answer:

427,786 Flowers

Step-by-step explanation:

135, 643 + 9,756 = 145,399

145, 399 + 1,345 = 146,744

135,643 + 145,399 = 281,042 + 146,744 = 427,786

Answer:

16 months to grow hair to 8 inches

Answer:

16

Step-by-step explanation:

So we know that one month = [tex]\frac{1}{2}[/tex] inch.

As a result, two months = 1 inch.

Double that.

4 months = 2 inches

8 months = 4 inches.

16 months = 8 inches.

It's always a 2:1 ratio.

Step-by-step explanation:

We do the reciprocal of 3/10 because we are dividing fraction. Which would be 10/3. Change the sign to multiplication because we are dividing fractions. And multiply regularly. SO it would be 3/5 times 10/3 = 2

Step-by-step explanation:

The graph that best shows the relationship between the number of days and the number of frozen treats sold will be a straight line with slope of 120 and will pass through origin. the equation representing the scenerio would be y = 120x

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

Equation : y = Kx also represent constant proportionality.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is the owner of a food cart sells an average of 120 frozen treats per day during the summer.

The given situation represents a direct proportionality between the number of frozen treats sold  vs  the number of days. The graph that best shows this relationship between the number of days and the number of frozen treats sold will be a straight line with slope of 120 and will pass through origin. Mathematically, the equation would be -

y = 120x

Therefore, the graph that best shows the relationship between the number of days and the number of frozen treats sold will be a straight line with slope of 120 and will pass through origin. the equation representing the scenerio would be y = 120x

Answer:

Sine of the Angle = opposite / hypotenuse

Sine Angle = 22.8 / 24

Sine Angle = .95

Angle = arc sine (.95)

Angle =  71.805 degrees

Angle = 71.8 (rounded)

Step-by-step explanation:

Answer:

71.8

Step-by-step explanation:

Step-by-step explanation:

S = ∫ 2π y ds

ds = √(1 + (dx/dy)²) dy

ds = √(1 + (8y)²) dy

ds = √(1 + 64y²) dy

S = ∫₁² 2π y √(1 + 64y²) dy

S = π/64 ∫₁² 128y √(1 + 64y²) dy

S = π/64 [⅔ (1 + 64y²)^(³/₂)] |₁²

S = π/96 (1 + 64y²)^(³/₂) |₁²

S = π/96 (1 + 256)^(³/₂) − π/96 (1 + 64)^(³/₂)

S = π/96 (257√257) − π/96 (65√65)

S = π/96 (257√257 − 65√65)

Answer:

(0, 7)

Step-by-step explanation:

Given:

J(-4, 11)

K(8, -1)

JP:JK = 1/3

Required:

Coordinates of P

SOLUTION:

Use the formula, [tex] (x, y) = (x_1 + k(x_2 - x_1), y_1 + k(y_2 - y_1)) [/tex] to find the coordinates of point P, that partition the segment JK into the ratio 1/3.

Let,

[tex] J(-4, 11) = (x_1, y_1) [/tex]

[tex] K(8, -1) = (x_2, y_2) [/tex]

[tex] k = \frac{1}{3} [/tex]

Thus, plug in the values as follows:

[tex] P(x, y) = (-4 + \frac{1}{3}(8 -(-4)), 11 + \frac{1}{3}(-1 - 11) [/tex]

[tex] P(x, y) = (-4 + \frac{1}{3}(12), 11 + \frac{1}{3}(-12) [/tex]

[tex] P(x, y) = (-4 + \frac{12}{3}, 11 + \frac{-12}{3}) [/tex]

[tex] P(x, y) = (-4 + 4, 11 + (-4) [/tex]

[tex] P(x, y) = (0, 7) [/tex]

The coordinates of point P, are (0, 7)
