B, is the correct answer.
7% of 450 is 31.5
We add 31.5 to 450 to find out highest possible error, and subtract 31.5 from 450 to find out lowest possible error.

A garden measuring 12 meters by 6 meters is going to have a walkway constructed all around the perimeter, increasing the total a

damaskus [11]

Answer:

x=2

Step-by-step explanation:

Original width = 6

New width 6+x+x

Orignal length 12

New length 12+x+x

A = l*w

160 = ( 6+2x) ( 12+2x)

Factor

160 = 2( 3+x) 2(6+x)

Divide each side by 4

40 = (3+x) (6+x)

FOIL

40 = 18+ 6x+3x+ x^2

40 = 18 +9x+x^2

Subtract 40 from each side

0 = x^2 +9x -22

Factor

0 = (x +11) (x-2)

Using the zero product property

x +11 =0 x-2 =0

x= -11 x=2

Since we cannot have a negative sidewalk

x =2

jay beats terry at table tennis 3 out of 5 games. what is the experimental probability that terry will win their next game

lozanna [386]

Answer:

The experimental probability that terry will win their next game is $\frac{2}{5}$

Step-by-step explanation:

While theoretical probability is the ratio of the number of favourable outcomes to the total number of outcomes, the experimental probability is the ratio of number of times the event is occurring to the total number of trials of the experiment.

Out of 5 games jay wins 3

Now the experimental probability that terry will win their next game

= 1 - Probability of Jay winning the game----------------------(1)

Probability of Jay winning the game = $\frac{\text{number of occurrences of the event}}{\text{total number of trials made}}$
