Here is your answer

\bold{x=12}

REASON:

Concept used: The opposite sides of a parallelogram are equal.

So, in above given figure

3x+7=5x-17 (measures of opposite sides)

5x-3x= 17+7

2x= 24

x= 24/2

x= 12

rectangle A has a length of 24 meters and a width of 20 meters. rectangle B has the same area as rectangle A. the width of recta
blagie [28]
To solve this, first we'll find the area of the rectangle A,

Area=length × width
?=24m×20m
480m=24m×20m
480m squared=area of the rectangle A

now we'll find the width of rectangle B,
"the width of rectangle B is 12 meters less than the width of rectangle A",
20m-12m= 8m
8m=width of rectangle B

finally we'll find the length of rectangle B,
area of the rectangle B= 480msquared
width= 8m
length=? (to find this divide the area by the width)
480÷8=60m
length of the rectangle B=60m

A blind taste test will be conducted with 9 volunteers to determine whether people can taste a difference between bottled water
Aloiza [94]

Answer:

The answer is \frac{1}{256}

Step-by-step explanation:

If we assume that people cannot taste a difference between bottled water, then the probability of identifying tap water is 0.5

Thus, P(identify tap water)=0.5

The probability that at least 8 of the 9 people identify the tap water correctly is the sum of the probabilities

  • 8 of 9 people identified correctly or
  • 9 of 9 people identified correctly

Since P(identify tap water)=0.5 each probabilities are the same and equal to

0.5^9 =\frac{1}{512}

So we have 2*\frac{1}{512} = \frac{1}{256}
