Algebra 1 question : Solve for x : 3 - 5x + 6 = 14x - 32 + 10(2-x)
Zepler [3.9K]
Hi there!

3 - 5x + 6 = 14x - 32 + 10(2 - x)
Work out the parenthesis.

3 - 5x + 6 = 14x - 32 + 20 - 10x
Combine like terms.

9 - 5x = 4x - 12
Subtract 9 from both sides.

- 5x = 4x - 21
Subtract 4x from both sides

- 9x =  - 21
Divide both sides by -9

x =  \frac{ - 21}{ - 9}  =  \frac{21}{9}  = 2 \frac{3}{9}  = 2 \frac{1}{3}

Which of the following statements are true of the hypotenuse of a right triangle? Select all that apply. A.) It is the longest s
kirza4 [7]
<span>True    A.) It is the longest side of a right triangle.
False  B.) It is one of the legs. It is opposite the right angle.
False  C.) Its length is the sum of the lengths of the other two sides.
False  D.) It forms a right angle with an adjacent side.

If option B is a single choice, then it has to be called false.

Look at option B.
B. "It is one of the legs" is false.
"It is opposite the right angle" is true.
Are you sure option B. is not two different choices, and there are really 5 choices instead of 4?

Refer to the accompanying​ TI-83/84 Plus calculator display of a​ 95% confidence interval. The sample display results from using
Darina [25.2K]

Answer:

[22.57 ± 2.776]

Step-by-step explanation:

Hello!

You have the 95% Confidence Z-interval (21.182;23.958), the mean X[bar]= 22.57 and the sample size n=25.

The formula for the Z interval is

[X[bar] ± Z_{1-\alpha /2} *( \frac{Sigma}{\sqrt{n} } )]

The value of Z comes from tha standard normal table:

Z_{1-\alpha /2} = Z_{0.975}= 1.96

The semiamplitude (d) or margin of error (E) of the interval is:

E or d= (Upperbond- Lowerbond)/2 = (23.958-21.182)/2 = 2.776

[X[bar] ± E]

[22.57 ± 2.776]

I hope it helps!
