Answer:

1/6

Step-by-step explanation:

Out of these four card choices, for the first pick there are two even cards and four cards in total. This means that on the first pick there is a 2/4=1/2 chance that you pick an even card. On the second pick, if you do not replace the card, then there is 1 even card remaining, and 3 cards in total, leaving a probability of 1/3. Multiplying these two probabilities together, you get an overall chance of 1/6. Hope this helps!

A rectangle is 12 cm long and 9 cm wide. Its diagonal is labeled 2x - 11. What is the value of x?

shusha [124]

Answer: The value of x is 13 cm.

Explanation:

It is given that the length and width of the rectangle are 12 cm and 9 cm.

Use pythagoras to find the value of the diagonal.

$Hypotenuse=\sqrt{(base)^2+(perpendicular)^2}$

$D=\sqrt{(12)^2+(9)^2}$

$D=\sqrt{144+81}$

$D=\sqrt{225}$

$D=15$

It is given that the diagonal is labeled as 2x-11.

$2x-11=15$

$2x=15+11$

$2x=26$

Divide both side by 2.

$x=13$

Therefore, x = 13cm.

Answer:

Yes, Fiona is correct

Step-by-step explanation:

WHen the pythagorean theorem is applied to the side lengths (2^2 + 4^2 = c^2), the result for c^2 is 20. The correct answer would be sqrt.20. But Fiona is also correct becuase sqrt of 20 can be simplified to sqrt.4 * sqrt.5; which equals 2*sqrt.5
