A shelf is designed so it will fit in a 90º corner between two walls. The shelf has dimensions, rounded to the nearest tenth, as

den301095 [7]

Answer:

Yes, it will fit snugly in a 90º corner

Step-by-step explanation:

To do this, we simply need to check if the given sides of the shelf is right-angled.

So, we have:

$Hypotenuse = \sqrt{242$

$Side\ 1 = Side\ 2 = 11$

To check for right-angle triangle, we make use of:

$Side\ 1^2 + Side\ 2^2 = Hypotenuse^2$

This gives:

$11^2 + 11^2 = \sqrt{242}^2$

$121 + 121 = \sqrt{242}^2$

$242 = \sqrt{242}^2$

$242 = 242$

This shows that the given sides of the shelf is a right-angled triangle.

Hence, it will fit the wall

Alla [95]

Answer:

The point estimate for this problem is 0.48.

Step-by-step explanation:

We are given that a University wanted to find out the percentage of students who felt comfortable reporting cheating by their fellow students.

A survey of 2,800 students was conducted and the students were asked if they felt comfortable reporting cheating by their fellow students. The results were 1,344 answered "Yes" and 1,456 answered "no".

Let $\hat p$ = proportion of students who felt comfortable reporting cheating by their fellow students

Now, point estimate ( $\hat p$ ) is calculated as;

$\hat p=\frac{X}{n}$

where, X = number of students who answered yes = 1,344

n = number of students surveyed = 2,800

So, Point estimate ( $\hat p$ ) = $\frac{1,344}{2,800}$

= 0.48 or 48%

given a polynomial and one of its factors, find the remaining factors of the polynomial. some factors may not be binomials. use

Alenkinab [10]

This is easy to do because you can factor
example
6/2=3 because 6=2*3 so 6/2=3/1 times 2/2 or 3

2x^3+17x^2+23x-42 can be factored out to equal
(x-1)(x+6)(2x+7)

so [(x-1)(x+6)(2x+7)]/(2x+7)=[(x-1)(x+6)] times (2x+7)/(2x+7)=(x-1)(x+6)=x^2+5x-6

the answer is (x-1)(x+6) or x^2+5x-6

20 points! Thank you

$HEY THERE !!$

Factorization of the trinomial
3x^3 +6x^2 -24x
will be :-

taking common 3x

=>3x(x^2+2x-12)......1️⃣

now the factorization of (x^2+2x-12) will be
(x-2)(x+4).......2️⃣

so your answer from 1️⃣and 2️⃣ is (A) 3x(x-2)(x+4).

Hope it helped you.
