7 0

Answer:

Step-by-step explanation:

(9.72 × $10^{8}$ ) + (1.93 × $10^{7}$ )

Take out $10^{7}$ as a common factor

= $10^{7}$ (9.72 × 10 + 1.93)

= $10^{7}$ (97.2 + 1.93)

= $10^{7}$ × 99.13

= $10^{7}$ × 9.913 × $10^{1}$

= 9.913 × $10^{8}$ → B

Answer:

11/306

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that there are 4 red, 8 yellow, and 6 blue socks in a drawer where the probability of picking a red, yellow and blue socks be p(r), p(y), and p(b) respectively.

The probability of reaching into the drawer without looking and drawing out 2 blue socks

= 6/(4 + 8 + 6) * 5/(4 + 8 + 5)

= 6/18 + 5/17

= 11/306

The variables X, Y, and Z represent polynomials where X = a, Y = 3a – 5, and Z = a^2 + 2. What is X^2Y – Z in simplest form?

klasskru [66]

$X=a \\
Y=3a-5 \\
Z=a^2+2 \\ \\
X^2Y-Z=a^2(3a-5)-(a^2+2)=3a^3-5a^2-a^2-2=3a^3-6a^2-2$

The answer is b.
