Answer:

Move the negative sign to the left.

-x+6/2=-1

Multiply both sides by 2

-x-6=-1 x 2

simplify 1 x 2 to 2

-x-6=-2

add 6 to both sides

-x=-2+6

simplidy -2+6 to 4

-x=4

multiply both sides by -1

x=-4

Multiply both sides with -2
X + 6 = 2
X = 2 - 6
X = -4

You would write your 2 ordered pairs based on the year and the amount of yogurt sold in that year.

The x-value (your first number in the ordered pair) the year and the y-value (the 2nd number in the ordered pair) the amount of yogurt.

(2002, 2133) and (2007, 3478) would be your 2 ordered pairs.

A multiple choice exam has 20 questions. Each question has 3 possible answers; there is no partial credit. Only 1 answer out of
amid [387]

Answer:To find out the theoretical probability of the case given, we need to make certain assumptions.

First, we'll assume that he'll attempt all of the questions, i.e he'll attempt all 10 questions.

Next assumption is that each option in each question is equally likely to be marked by the student.

This pretty much leads us to a binomial probability distribution.

Conditions are:

   Answers 10 questions.

   Each question has 4 options with only one correct answer and all other incorrect answers.

   Student is equally likely to pick any outcome in any given question.

   Hence, probability of choosing correct answer is 1/4 = 0.25. Probability of choosing incorrect answer is 1–1/4 = 3/4 = 0.75.

   The number of trials is 10.

   Total number of success is exactly 8 and failure is 2 amongst the 10 questions in any particular order.

Now, calculation is fairly simple.

Binomial probability distribution is such that…

P(8 correct ; 2 wrong)

= 10C8 × (0.25)^8 × (0.75)²

= 405/1048576 ≈ 3.862380981 × 10^-4 ≈ 0.000386

Which of the following has a value this is less than zero? A:(-6)^2 B:1/3 x 2 C:0.5^2 D:-7^2
solniwko [45]

The value of -7² is less than zero which is the correct answer would be an option (D)

<h3>What is the fraction?</h3>

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

<h3>What are Arithmetic operations?</h3>

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

To determine the value is less than zero

Option A: (-6)² ⇒ 36

So this value is greater than zero

Option B: 1/3 × 2 ⇒ 2/3

So this value is greater than zero

Option C: 0.5² ⇒ 0.25

So this value is greater than zero

Option D: -7² ⇒ -49

So this value is less than zero

ella [17]

Answer:

The standard deviation of the sampling distribution of x overbarx​, denoted sigma Subscript x overbarσx​, is called the​ standard error of the mean . The standard deviation of the sampling distribution of x overbarx​, denoted sigma Subscript x overbarσx​, is called the standard distribution of the sample.

Step-by-step explanation:

The standard error (SE) of a statistic is the standard deviation of its sampling distribution or an estimate of that standard deviation. It is called the standard error of the mean (SEM) if the parameter or the statistic is the mean.
