Answer:

See below

Step-by-step explanation:

4k - 3 = 2k + 5 Given

4k - 3 -2k = 2k + 5 - 2k Addition (added -2k to both sides )

4k - 2k - 3 = 2k - 2k + 5 Commutative (changed the order of the terms)

2k - 3 = 0 + 5 Addition/ Identity

2k - 3 = 5 Addition

2k - 3 + 3 = 5 + 3 Addition (added 3 to both sides)

2k + 0 = 8 Addition

2k = 8 Identity

Explain how to find vertical and horizontal asymptotes of a rational<br> equation.

AleksandrR [38]

Answer:

Step-by-step explanation: If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0).

If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

Using property find <br>a.3/5×-2/7+4/5-3/10×2/7

Sedaia [141]

Here the answer is 19/35

Step-by-step explanation:

$\frac{3}{5} X\frac{-2}{7} +\frac{4}{5}-\frac{3}{10} X\frac{2}{7}$

We will apply BODMAS rule

In this rule multiplication comes before add and subtraction

= $\frac{-6}{35} + \frac{4}{5} - \frac{3}{35}$

= $\frac{4}{5} - ( \frac{6}{35}+ \frac{3}{35})$

= $\frac{4}{5} - \frac{9}{35}$

= $\frac{4 X 7}{5 X 7} -\frac{9}{35}$

= $\frac{28}{35} - \frac{9}{35}$

= $\frac{19}{35}$

In a hypothetical study, researchers found that the average donut sold by Krispy Kreme contains 260 calories, with a standard de

VladimirAG [237]

Answer:

Option C) 0.57

Step-by-step explanation:

We are given the following in the question:

Average, $\mu_0$ = 260 calories

Standard deviation, $\sigma$ = 35 calories

$\mu_1$ = 240 calories.

We have to find the Cohen's d effective size.

Formula:

$d = \bigg|\dfrac{\mu_1 - \mu_0}{\sigma}\bigg|\\\\d = \bigg|\dfrac{240-260}{35}\bigg|\\\\d = 0.57$

Thus, the Cohen's d effective size is 0.57

Thus, the answer is

Option C) 0.57
