PLEASE HELP!!!!! x^2 + 12xy + 35y^2

2 answers:

7 0

The answer is = (x + 5y) (x + 7y)

Break the expression into two groups.

x^2 + 12xy + 35y^2
(x^2 + 5xy) (7xy + 35^2)

Factor out x from x^2 + 5xy: x(x + 5y)
Factor out 7y from 7xy + 35y^2: 7y(x + 5y)
=x(x + 5y) + 7y(x + 5y)

Next, factor out the common term (x+ 5y).

Answer = (x + 5y) (x + 7y)

By grouping, the answer is (x+5y)(x+7y)

If five numbers are selected at random from the set {1,2,3,...,20}, what is the probability that their minimum is larger than 5?

Zanzabum

Answer:

the probability that their minimum is larger than 5 is 0.2373

Step-by-step explanation:

For calculate the probability we need to make a división between the total ways to selected the 5 numbers and the ways to select the five numbers in which every number is larger than 5.

So the number of possibilities to select 5 numbers from 20 is:

20 * 20 * 20 * 20 * 20

First number 2nd number 3rd number 4th number 5th number

Taking into account that a number can be chosen more than once, and the order in which you select the numbers matters, for every position we have 20 options so, there are $20^{5}$ ways to select 5 numbers.

Then the number of possibilities in which their minimum number is larger than 5 is calculate as:

15 * 15 * 15 * 15 * 15

First number 2nd number 3rd number 4th number 5th number

This time for every option we can choose number from 6 to 20, so we have 15 numbers for every option and the total ways that satisfy the condition are $15^{5}$

So the probability P can be calculate as:

$P=\frac{15^{5} }{20^{5} } \\P=0.2373$

Then the probability that their minimum is larger than 5 is 0.2373

(Geometry HELP) The perimeter of WXY is ___ cm?

jeka57 [31]

I hope this helps you

QR=WS=2.93

RS=QW =2.04

QS=XR =2.28

RS=XQ=2.04

SY=QR =2.93

RY=QS =2.28

XY=XR+RY=2.28+2.28=4.56

XW=XQ+QW=2.04+2.04=4.08

WY=WS+SY=2.93+2.93=5.86

Perimeter of XYW=XW+WY+XY

Perimeter of XYW=4.08+5.86+4.56

Perimeter of XYW =14.5

Helpppppp!!!!!!!!!!!!!

The outlier would be 28 because it is much lower than the rest of the numbers in the group and removing it would make the mean increase.
