Given: y=x^3 and y=343
So, 343=x^3
Cube root both sides which will get rid of the cube on the right side of the equation
You are left with the cube root of 343. Which equals 7.
7*7*7=343
X=7

Suppose that Matthew can choose to get home from work by car or bus.

Verizon [17]

Answer:

B-91%

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)}$

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: arriving home after 7 p.m.

Event B: getting home by bus.

When he chooses to get home by bus, he arrives home after 7 p.m. 25 percent of the time.

This means that $P(A|B) = 0.25$

Because the bus is cheaper, he uses the bus 70 percent of the time.

This means that $P(B) = 0.7$

Probability of getting home after 7 p.m.

70% of the time he uses bus, and by bus, he arrives arrives home after 7 p.m. 25 percent of the time.

100 - 70 = 30% of the time he uses the car, and by car, he arrives home after 7 p.m. 6 percent of the time.

So

$P(A) = 0.7*0.25 + 0.3*0.06 = 0.193$

What is the approximate probability that Matthew chose to get home from work by bus, given that he arrived home after 7 p.m.?

$P(B|A) = \frac{0.7*0.25}{0.193} = 0.9067$

Rouding up, 91%.

So the correct answer is:

B-91%

Pyramid P is similar to pyramid Q. The volume of pyramid P is 980 c m cubed, and the volume of pyramid Q is 3307.5 c m cubed. Wh

jeka57 [31]

Answer:

The scale factor is $\frac{3}{2}$

Step-by-step explanation:

The volume of the original prism is $V_P=980cm^3$

The volume of the dilated prism is $V_Q=3307.5cm^3$

Let the scale factor be $k$ .

To find the volume of the dilated prism, we multiplied by $k^3$ .

$\Rightarrow 980k^3=3307.5$

$\Rightarrow k^3=\frac{3307.5}{980}$

$\Rightarrow k^3=\frac{27}{8}$

$\Rightarrow k=\sqrt[3]{\frac{27}{8}}$

$\Rightarrow k=\frac{3}{2}$
