elect the correct answer from each drop-down menu. A system of linear equations is given by the tables. x y -5 10 -1 2 0 0 11 -2

sergeinik [125]

Answer:

First equation: y = -2x

Second equation: y = 3 - x

Solution: (1, -2)

Step-by-step explanation:

Assuming the ordered pairs of the tables are:

Table 1

(-5, 10) (-1, 2) (0, 0) (11, -22)

Table 2

(-8, -11) (-2, -5) (1, -2) (7, 4)

To create a linear equation, pick 2 ordered pairs. Calculate the slope by using the slope formula, then use the points-slope form of the linear equation to form the equation.

$\textsf{slope }m=\dfrac{\textsf{change in }y}{\textsf{change in }x}$

$\textsf{point-slope form : }y-y_1=m(x-x_1)$

Equation 1

$\textsf{slope }m=\dfrac{2-10}{-1+5}=-2$

$y-0=-2(x-0)\\\\\implies y=-2x$

Equation 2

$\textsf{slope }m=\dfrac{-5+11}{-2+8}=1$

$y+11=1(x+8)\\\\\implies y=x-3$

Solution to the System

Equate the equations and solve for x:

-2x = x - 3

⇒ 0 = 3x - 3

⇒ 3x = 3

⇒ x = 1

Substitute found value of x into one of the equations and solve for y:

y = 1 - 3 = -2

Therefore, the solution is (1, -2)

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

The average of six numbers is 4. If the of two of those numbers is 2, what is the average of the other four numbers?

matrenka [14]

Answer:

Step-by-step explanation:

total sum of the 6 numbers

= 4 ×6

= 24

sum of numbers without the two 2s

= 24 - 2(2)

= 20

average of other 4 numbers

= 20 ÷ 4

= 5
