Answer:

The researchers think that 65% of college students will graduate with debt when, in fact, more or less than 65% of college students will graduate with debt.

Step-by-step explanation:

A Type II error is the decision not to reject the null hypothesis when, in fact, it is false. In this case, the Type II error is when the researchers think that 65% of college students will graduate with debt when, in fact, more or less than 65% will graduate with debt.

<h2>Answer with explanation:</h2>

We know that in statistics, the Type II error happens when the null hypothesis is false but fails to get rejected.

Given : The null hypothesis, H_0, is: researchers claim that 65% of college students will graduate with debt.

Then , Type II error in this scenario will be when the researcher claim 65% of college students will graduate with debt is false but fails to be rejected.

x-3

Step-by-step explanation:

(x^2-9)(x^2-9)/x^2*(x+3)+9(x+3)

(x+3)*(x^2+9)/(x+3)*(x^2+9) cross multiply

(x^2+9)*(x+3)/(x^2+9) cross multiply

Use the identity (x^2+y^2)^2=(x^2−y^2)^2+(2xy)^2 to determine the sum of the squares of two numbers if the difference of the squ
marissa [1.9K]

Answer:

Step-by-step explanation:

(x^2+y^2)^2=(x^2)^2+2x^2y^2+(y^2)^2

Adding and substracting 2x^2y^2

We get

(x^2+y^2)^2=(x^2)^2+2x^2y^2+(y^2)^2 +2x^2y^2-2x^2y^2

And we know a^2-2ab+b^2=(a-b)^2

So we identify (x^2)^2 as a^2 ,(y^2)^2 as b^2 and -2x^2y^2 as - 2ab. So we can rewrite (x^2+y^2)^2=(x^2 - y^2)^2 + 2x^2y^2 + 2x^2y^2= (x^2 - y^2)^2+4x^2y^2= (x^2 - y^2)^2+2^2x^2y^2

Moreever we know (a·b·c)^2=a^2·b^2·c^2 than means 2^2x^2y^2=(2x·y)^2

And (x^2+y^2)^2=(x^2 - y^2)^2 + (2x·y)^2

What is the answer to this maths watch question? Look at screenshot attached. Thank you.
forsale [732]

14-x=9

14=x+9

x=14-9

x=5

14+5=19

x+y=19

x-y=(-5)

Adding both equations,

We get,

x+y=19

x-y=(-5)

2x=14

x=7

x+y=19

7+y=19

y=12
