Evaluate √x^2 + y^2 when x^2 =20 and y^2 =10

schepotkina [342]

Answer:

5.477

Step-by-step explanation:

Here we have to get the value √ ( x²+y² ) in this question where the values of x² and y² are given to be 20 and 10 respectively.

Let A = √ ( x²+y² ) =√(20+10) {Since the value of x² =20 and that of y² =10}

⇒ A= √30 =5.477

Therefore, the value of √ ( x²+y² ) is 5.477. (Answer)

Customers are used to evaluate preliminary product designs. In the past, 95% of highly successful products received good reviews

maks197457 [2]

Answer:

Step-by-step explanation:

The given information can be tabulated as follows.

Success type High Moderate Low Total

0.40 0.35 0.25 1

Good reviews 0.95 0.60 0.10

Combined prob 0.4*0.95 0.35*0.6 0.25*0.1

0.38 0.21 0.025 0.6125

A) the probability that a product attains a good review

=Prob it it successful and gets good review + Prob it is moderate successful and gets good review +Prob it it low successful and gets good review

= 0.6125

B) If a new design attains a good review, the probability that it will be a highly successful product= $\frac{0.38}{0.6125} \\=0.6204$

C) Prob that does not attain a good review =(0.40*0.05)+0.35(0.4) +(0.25)*0.9

= 0.385

Prob for successful not getting good review = 0.40(0.05) = 0.02

Reqd prob = $\frac{0.02}{0.385} \\=0.05195$

a piece of luggage sells for $225.00 it is on sale this week for $195.00 what is the percent decrease to the nearest whole perce

viktelen [127]

Answer: 13%

Step-by-step explanation:

Given : A piece of luggage sells for $225.00 it is on sale this week for $195.00 .

Decrease in price = $225.00-$195.00= $30.00

Formula to find the percent decrease :-

$\dfrac{\text{Decrease in price}}{\text{Previous price}}\times100\\\\=\dfrac{30}{225}\times100=13.3333333333\approx13\%\ \ [\text{Rounded to the nearest whole percent.}]$

Hence, the percent decrease = 13%
