Any one that knows this please help thanks!

Replace the x with 9, and the y with 1.

(x · y²)/-5 becomes (9 · 1²)/-5

1² is just 1, so you're doing 9 × 1 (which is = 9) over -5.

Therefore, your final answer is -9/5.

A normal distribution has a mean of 10 and a standard deviation of 1. What is the probability of selecting a number that is at m
Len [333]

Answer: 0.500

Step-by-step explanation:

Given : A normal distribution has a mean(\mu) of 10 and a standard deviation(\sigma) of 1.

Let x be a random variable that represents numbers .

The probability of selecting a number that is at most 10 will be

P(x\leq10)=P(\dfrac{x-\mu}{\sigma}\leq\dfrac{10-10}{1})\\\\=P(z\leq0)=0.500

As the area occupied by standard normal curve less than equal to 0 = 0.500

So, required probability = 0.500

How to solve this plss frac{(\sqrt{(3)})^{5}}{((\sqrt{(3)})^{-4})}=(\sqrt{(3)})^{(2k+1)​
dusya [7]

Answer:

k = 4

Step-by-step explanation:

Given equation:

\dfrac{(\sqrt{3})^{5}}{(\sqrt{3})^{-4}}=(\sqrt{3})^{(2k+1)}

\textsf{Apply exponent rule} \quad \dfrac{a^b}{a^c}=a^{b-c}:

\implies (\sqrt{3})^{(5-(-4))}=(\sqrt{3})^{(2k+1)}

\implies (\sqrt{3})^{9}=(\sqrt{3})^{(2k+1)}

\textsf{Apply exponent rule} \quad a^{f(x)}=a^{g(x)} \implies f(x)=g(x):

\implies (\sqrt{3})^{9}=(\sqrt{3})^{(2k+1)}

\implies 9=2k+1

\implies 2k=8

\implies k=4
