A) Since there are 3 (3,5,7) odd primes between 0-9 and there are 10 blocks from 0-9, the probability is 3/10

B) Since there are 3 (1,4,9) perfect squares above 0 and there are a totally 10 blocks from 0-9, the probability is 3/10.

Answer:P(Prime number) = 0.4

P(Perfect Square>0) =0.1

Step-by-step explanation:There is 10 numbers in the box.

Out of the 10 numbers 4 are prime numbers (2 3 5 7) the probability to pick a prime number is thus 4/10=0.4

The only number greater than zero that is a perfect square is 4. The probability of picking a perfect square bigger than zero is thus 1/10=0.1

Answer:

Step-by-step explanation:

$\dfrac{a^{m}}{a^{n}}=a^{m-n}\\\\\dfrac{-8y^{10}}{2y^{5}}=\dfrac{-4y^{10}}{y^{5}}=-4*y^{10-5}= -4y^{5}$

Answer: D

Multiplying the x^3 term by 4 means it’s stretching it vertically, adding the minus sign means it’s flipping it about the x-axis, and subtracting 5 means it’s moving it down by 5 units.
