Answer:

r·sin Ф = 5(r·cos Ф) - 2

Step-by-step explanation:

y = r·sin Ф and x = r·cos Ф, and so

y = 5x - 2 becomes

r·sin Ф = 5(r·cos Ф) - 2

Which set of absolute values is compared correctly?

stepan [7]

I would say D because, it makes sense the most, absolute values make the negatives positive, so the order that D goes in is correct.

Hey there! :)

Answer:

r ≈ 4.38 cm.

Step-by-step explanation:

Find the radius by working backwards using the equation A = πr²:

Given:

A = 60.24 cm²

π = 3.14

Plug these into the equation:

60.24 = 3.14r²

Divide both sides by 3.14:

19.185 = r²

Take the square root of both sides:

r ≈ 4.38 cm.

Assume that random guesses are made for seven multiple choice questions on an SAT test, so that there are nequals7 trials, eac

Ket [755]

Answer:

$P(X < 4)=0.1335+0.3115+0.3115+0.1730=0.9295$

Step-by-step explanation:

Question assumed: Find the probability that the number x of correct answers is fewer than 4.

1) Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

2) Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=7, p=0.25)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want to find this probability:

$P(X < 4)=P(X=0)+P(X=1)+P(X=2)+P(X=3)$

$P(X=0)=(7C0)(0.25)^0 (1-0.25)^{7-0}=0.1335$

$P(X=1)=(7C1)(0.25)^1 (1-0.25)^{7-1}=0.3115$

$P(X=2)=(7C2)(0.25)^2 (1-0.25)^{7-2}=0.3115$

$P(X=3)=(7C3)(0.25)^3 (1-0.25)^{7-3}=0.1730$

$P(X < 4)=0.1335+0.3115+0.3115+0.1730=0.9295$
