If B equals 7 what is the value of the expression 2 + (10 - B )?

avanturin [10]

We just need to <u>plug in 7 for B! </u>

Let's do it !

2 + (10 - 7)

<em>We always start with the parenthesis first ! It's just a rule in math :) </em>

10 - 7 = ?

10 - 7 = 3

Now we have ...

2 + 3

2 + 3 = 5

Your final answer is 5!

If I am adding one positive number and one negative number, will the answer be positive or negative? What does it depend on?

maxonik [38]

It depends on which number has the greatest absolute value.

Think about it as money

If you owe me $10, this is shown as -10

Now if I give you back 2 dollars (+2), How much money do I still owe you.

The equation is -10+2

I still owe you 8 dollars which is portrayed as -8

Hope this helps :)

The standard deviation for a set of data is 6.5. The mean is 255. What is the Margin of Error?

HACTEHA [7]

Answer: The margin of error is 12.74.

Step-by-step explanation:

Since we have given that

Standard deviation = 6.5

Mean = 255

Let 95% level of significance,

So, z value = 1.96

We need to find the "Margin of error":

So, it becomes :

Margin of error = Standard deviation × z-value

Margin of error = $6.5\times 1.96=12.74$

Hence, the margin of error is 12.74.

The radius of the circle below intersects the unit circle at (Three-fifths, four-fifths). What is the approximate value of Theta

Fudgin [204]

The measured value of Theta is 53.1 degrees.

Given

The radius of the circle below intersects the unit circle at (3/5, 4/5).

<h3>What is tan theta?</h3>

The measure of the tan angle is defined as the ratio of perpendicular by the base.

The measure of the tan theta is;

$\rm Tan\theta=\dfrac{x}{y}$

Where the value of x is 3/5 and y is 4/5.

Substitute all the values in the formula

$\rm Tan\theta=\dfrac{x}{y}\\\\\rm Tan\theta=\dfrac{\dfrac{4}{5}}{\dfrac{3}{5}}\\\\\\Tan\theta = \dfrac{4}{5} \times \dfrac{5}{3}\\\\Tan \theta=\dfrac{4}{3}\\\\\theta=tan{-1}(\dfrac{4}{3})\\\\\theta=53. 1 \ degrees\\\\$

Hence, the measured value of Theta is 53.1 degrees.
