Jamie is an analyst at an education technology company. She gathered data on the results of a certain type of question. Of the 2,000 responses she looked at, 1,092 responded correctly. What equation could Jamie use to calculate the margin of error at a 90% confidence interval?

Answers

Answer:

1st Square - 1.65

2nd Square - 0.546

3rd Square - 0.546

4th Square - 2000

(got it right on edmentum)

for better understanding of what I mean please take your time to look at the picture below↓

Step-by-step explanation:

The margin of error for the 90% confidence interval with a probability of success of 0.546 is 0.0183.

What is the margin of error?

The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.

Jamie is an analyst at an education technology company. She gathered data on the results of a certain type of question. Of the 2,000 responses she looked at, 1,092 responded correctly.

Then the value of p will be

[tex]\rm p = \dfrac{1092}{2000}\\\\p = 0.546[/tex]

And the z-value for the 90% confidence interval will be

[tex]\rm z = 1.645[/tex]

And N = 2000

Then the margin of error (ME) will be

[tex]ME = z \times \sqrt{\dfrac{p(1-p)}{N}}\\\\ME = 1.645\times \sqrt{\dfrac{0.546(1-0.546)}{2000}}\\\\ME = 0.0183[/tex]

Answer:

x = infinite amount of solutions

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Algebra I

Terms

Step-by-step explanation:

Step 1: Define Equation

10x - 6 + 2x = 4(3x - 1) - 2

Step 2: Solve for x

Combine like terms: 12x - 6 = 4(3x - 1) - 2Distribute 4: 12x - 6 = 12x - 4 - 2Combine like terms: 12x - 6 = 12x - 6Add 6 on both sides: 12x = 12xDivide 12 on both sides; x = x

Here we see that x does indeed equal x.

∴ any value x would work as a solution to the equation, hence we have infinite amount of solutions.

Answer:

The answer is infinite.

Step-by-step explanation:

So if you first simplify the problem you would have:

12x - 6 = 4 ( 3x - 1 ) - 2

I just combined like terms.

Then you distribute the 4 to the 3x and the negative 1.

So you would have 12x - 6 = 12x - 4 - 2

So once again you would combine like terms and get 12x - 6 = 12x - 6

If you simplified it out and subtracted like terms from both sides you would get 0 = 0 which is true so there is infinite solutions.

Answers

Answer:

$37623.04

Step-by-step explanation:

The formula we'll use for this is the simple interest formula, or:

[tex]I=p*r*t[/tex]

Where:

P is the principal amount, $1088.00.

r is the interest rate, 839.5% per year, or in decimal form, 839.5/100=8.395.

t is the time involved, 4....year(s) time periods.

So, t is 4....year time periods.

To find the simple interest, we multiply 1088 × 8.395 × 4 to get that:

The interest is: $36535.04

Usually now, the interest is added onto the principal to figure some new amount after 4 year(s),

or 1088.00 + 36535.04 = 37623.04.

5. The 7th grade has 386 students. There are 32 more girls than boys in the grade.
How many boys are in the 7th grade?

Answers

Answer:

161 boys

Step-by-step explanation:

First you find the even amount of boys and girls out of 386

386 divided by 2 = 193

Then you subtract 32 boys and add the 32 to girls since there are 32 more girls than boys

(boys) 193 - 32 = 161

(girls) 193 + 32 = 225

So there are 161 boys and 225 girls

[tex]Time = 3\frac{1}{2}\ hr[/tex]

Required

Determine the change in temperature per hour

This is calculated as:

[tex]Rate = \frac{T_2 - T_1}{Time}[/tex]

[tex]Rate = \frac{-12\frac{1}{4}^{\circ} - 0^{\circ}}{3\frac{1}{2}\ hr}[/tex]

[tex]Rate = \frac{-12\frac{1}{4}^{\circ} }{3\frac{1}{2}\ hr}[/tex]
