sin45=5/x so x is 5/(sin45)

y is 5/(tan45)

question 5 then you just go x= (9sqrt(2)/2)/sin45

i don’t have a calculator rn so just plug it into it

A population of voters contains 46% Republicans, 45% Democrats and the rest are Independents. Assume 50% of Republicans, 40% of

ICE Princess25 [194]

Answer:

The probability is 0.18

Step-by-step explanation:

Here, we are interested in calculating a conditional probability;

Let the event that a voter is a Republican be R , the event that a voter is a Democrat be D and that a voter is an independent is I

Let the event that the election issue is favored be F

We have the following probabilities;

P(R) = 46% = 0.46

P(D) = 45% = 0.45

P(I) = 1-0.45-0.46 = 0.09

The conditional probability we want to calculate is;

P(D | F) which can be read as probability of event D given event F

From the question, we can identify the following conditional probabilities;

P(F|R) = 0.46 * 0.5 = 0.23 (0.5 is gotten from 50% = 50/100)

P(F | D) = 0.45 * 0.4 = 0.18

P( F | I) = 0.09 * 0.6 = 0.054

P(F) = 0.054 + 0.18 + 0.23 = 0.464

Mathematically; From Baye’s theorem

P( D | F) ={ P ( F | D) * P(D) }/ P(F)

P( D | F) = (0.18 * 0.45)/0.464 = 0.1745

A sphere has a surface area of 80 square feet. Which choice is the closest to its radius? Use 3.14 to approximate pi.

solniwko [45]

Answer: 2.524 ft
----
The equation for the surface area of a sphere is $SA = 4 \pi r^2$ .
SA = surface area
r = radius

You're told that the surface area, SA = <span>80 square feet. Plug that into the equation and solve for r:
</span> $80 = 4 \pi r^2\\
20 = (3.14) r^2\\
 r^2 = \frac{20}{3.14} \\
r = \sqrt{ \frac{20}{3.14}}\\
r \approx 2.524 \: ft$ <span>
</span>
