katen-ka-za [31]

Answer: The explanation is correct.

Step-by-step explanation:

The interpretation of 95% confidence interval for population mean is that "A person can be 95% sure that the true population mean lies in it."

Given : The admissions director from Big City University found that (107.8, 116.2) is a 95% confidence interval for the mean IQ score of all freshmen.

Interpretation: The admissions director can be 95% sure that the true population mean IQ score of all freshmen lies in (107.8, 116.2).

i.e. There is a 95% probability (chance) that the interval from 107.8 to 116.2 contains μ.

Hence, the explanation is absolutely "correct" .

X^2-8x+16=5 what are the solutions?

svp [43]

Hey!

The first step to solving this equation would be to subtract 5 from both sides of the equation.

Original Equation :
$x^{2}$ - 8x + 16 = 5

New Equation {Added Subtract 5 to Both Sides} :
$x^{2}$ - 8x + 16 - 5 = 5 - 5

Now we solve our new equation.

Old Equation :
$x^{2}$ - 8x + 16 - 5 = 5 - 5

Solution {Old Equation Solved} :
$x^{2}$ - 8x + 11 = 0

The next step would be to solve with the quadratic formula.

Quadratic Equation ( 1 ) :
$x = \frac{-(-8) + \sqrt{(-8)^{2} -4 * 1 * 11 } }{2*1}$

Quadratic Equation ( 1 ) {Solved} :
4 + $\sqrt{5}$

Quadratic Equation ( 2 ) :
$x = \frac{-(-8) - \sqrt{(-8)^{2}-4 *1*11 } }{2*1}$

Quadratic Equation ( 2 ) {Solved} :
4 - $\sqrt{5}$

So, our final solutions for the equation $x^{2}$ - 8x + 16 = 5 are...

x = 4 + $\sqrt{5}$

and 

x = 4 - $\sqrt{5}$

Hope this helps!

PLS SOLVE RIGHT NOW WILL GIVE BRAINIEST 5 STARS AND THANKS 3 1/8 ÷(x−4 7/28 )= 17/18 +1 5/6

rusak2 [61]

Answer:

5 3/8

Step-by-step explanation:

3 1/8 ÷(x−4 7/28 )= 17/18 +1 5/6

Get a common denominator for the right side

3 1/8 ÷(x−4 7/28 )= 17/18 +1 15/18

Combine like terms

3 1/8 ÷(x−4 7/28 )= 1 32/18

3 1/8 ÷(x−4 7/28 )= 2 14/18

3 1/8 ÷(x−4 7/28 )= 2 7/9

We have a ÷ b = c

Rewriting as a ÷c = b

3 1/8 ÷ 2 7/9 = (x−4 7/28 )

Changing from mixed numbers to improper fractions

25/8 ÷ 25 /9 = (x−4 7/28 )

Copy dot flip

25/8 * 9/25 = (x−4 7/28 )

9/8 = (x−4 7/28 )

Add 4 7/28 to each side

9/8 + 4 7/28 = (x−4 7/28 )+ 4 7/28

Simplifying the fractions

9/8 + 4 1/4 = x

Getting a common denominator

9/8 + 4 2/8 =x

4 11/8 =x

4 + 8/8+3/8 =x

5 3/8
