Roman55 [17]

Answer:

a. $\frac{1}{17}$

b. $\frac{1}{16}$

Step-by-step explanation:

We are given that two cards are drawn are randomly selected from a standard 52- cards deck.

Total cards=52

Total number of spade cards=13

Probability= $\frac{number\;of\;favourable\;cases}{total\;number\;of cases}$

a.The probability of drawing two cards first card is spade and second card is spade without replacement = $\frac{13}{52}\times \frac{12}{51}$

The probability of drawing two cards first card is spade and second card is spade= $\frac{1}{17}$

b. The probability of drawing two cards first is spade and second card is a spade with replacement = $\frac{13}{52}\times\frac{13}{52}$

The probability of drawing two cards first is spade and second card is a spade with replacement = $\frac{1}{16}$

Kyle is 52 inches tall. The distance from the top of his head to the tip of his shadow is 60 inches. Approximately how long is K

Marizza181 [45]

Using Pythagoras's theorem, we can get that 60 inches is the hypotenuse and 52 inches is one of the legs. 60^2 - 52^2 = b^2, where b is the leg that we are trying to find, aka the length of the shadow. We find that b^2 = 896. The square root of 896 is closest to 30 inches, therefore the answer is A) 30 inches
