The answer would be -14 because 9-23=14

To check, subtract 23 from 9, and then add 23 back. :3

If x +23 = 9, then, x = 9-23.

So x = -14

What is the area of this polygon?<br><br><br><br> Enter your answer in the box.<br><br><br> units²
Cloud [144]

To find the area of the given polygon, first we will join P and S .

So we have two figures here, a rectangle GPST, and a triangle , PES .

Area of rectangle is length times width .

For the given rectangle, area is GP times PS .

GP= 2-(-3) = 2+3 =5 \\ PS = 4-(-3) = 4+3=7 \\ Area = 5* 7= 35 square \ units

And for triangle , area is half of the product of height and base.

For the given triangle,

Height = 4-2=2 \\ base=4-(-3)=7 \\ Area=(1/2)2*7 = 7 \ square \ units

Total area of the polygon is the sum of areas of rectangle and triangle , that is

Total \ area = 35+7 = 42 \ square \ units

Using the insurance company's assumptions, calculate the probability that there are fewer than 3 tornadoes in a 14-year period.
11Alexandr11 [23.1K]

Answer:  19.2222

Step-by-step explanation:

given data;

no of tornadoes = 2,1,0 because it’s fewer than 3.

period = 14 years

probability of a tornado in a calendar year = 0.12

solution:

probability of exactly 2 tornadoes

= ( 0.12 )^2 * ( 0.88 )^11 * ( 14! / 2! * 11! )

= 0.0144 * 0.2451 * 1092

= 3.8541

probability of exac one tornado

= ( 0.12 )^1 * ( 0.88 )^12 * ( 14! / 1! * 12! )

= 0.12 * 0.2157 * 182

= 12.7109

probability of exactly 0 tornado

= ( 0.12 )^0 * ( 0.88 )^13 * ( 14! / 0! * 13! )

= 1 * 0.1898 * 14

= 2.6572

probability if fewer than 3 tornadoes

= 3.8541 + 12.7109 +2.6572

= 19.2222

The Rodriguez family and the Hill family each used their sprinklers last summer. The water output rate for the Rodriguez family'
brilliants [131]

Answer:

x = 23.33 hr    Rodriguez sprinkler

y  = 26.66 hr   Hill sprinkler

Step-by-step explanation: INCOMPLETE QUESTION

Requiered information:

the water output rate for both sprinkler families

We assume : Rodriguez family   40 lts/hr

                      Hill family   35 lts/ hr

Total water output  1900 lts

and total combined hours working is 50 hr

Let call  "x"  time in hours sprinkler of Rodriguez family worked

and "y" time in hours sprinkler of  Hill  family worked

Then if total output was 1900 lts

40*x  +  35*y  = 1900    and   x  +  y  =  50

We have a two equation system, solving

y  =  50 - x     ⇒     40*x  +  35 * ( 50 - x )

40x  =  1750 -  35x

75 x  =  1750        ⇒    x  = 1750/75          ⇒    x = 23.33 hr

and   y  =  50  -  23.33     ⇒   y  =  26.66 hr
