Answer:

x = 34 (btw my friend helped me with this one)

Step-by-step explanation:

X+(3X+r)+R=180 right? Basic math (r is the small angle that form up PSR with 3X, R is just angle SRP)

x+(3X+r)+R=180

Put that to aside, next we have (3x+r)+T=180(T being TSP) yes?

But T+4x also=180

=>4x+(3x+r)

Next we have 68+3x+R=180 (smaller triangle)

Now we have all that, cramp them all together

We have two equations 68+3x+R=180 and x+(3x+r)+R=180

But 4x=3x+r sooo

Now we have 68+3x+R=180 or 3x+R=180-68

And 4x+x+R=1800 or 5x+R=180

Use the formula that i dont know the name of and calculate

x= 34 and R=10 how to check? 3x+R+68=3*34+10+68=180

Answer:

34=x

Step-by-step explanation:

180-68 =112 so angle PQS is 112 4x-3x is x so PSQ is x and now you can do x +x + 112 = 180 2x-68 x=34

I probably got it wrong tho, so sorry if it is incorrect

The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift.

NeX [460]

Answer:

0.674

Step-by-step explanation:

If the random variable X is exponentially distributed and X has an average value of 25 minutes, then its probability density function (PDF) is

$\bf f(x)=\frac{1}{25}e^{-x/25}\;(x\geq 0)$

and its cumulative distribution function (CDF) is

$\bf P(X\leq t)=\int_{0}^{t} f(x)dx=1-e^{-t/25}$

So, <em>the probability that X is less than 28 minutes is </em>

$\bf P(X\leq 28)=1-e^{-28/25}=1-e^{-1.12}=0.674$

A standard deck of has 52 cards, and contains 13 cards of each of the four suits: diamonds, spades, hearts, and clubs. What is t

Verizon [17]

Answer: $\frac{13}{51}$

Step-by-step explanation:

Given: Number of cards in a standard deck = 52

If we already chosen a diamond card, then the number of cards left in the deck =52-1=51

The number of spades remains same = 13

Now, the probability that you choose a spade, given that you have already chosen a diamond is given by :-

$P(Spade|diamond)=\frac{13}{51}$

Hence, the the probability that you choose a spade, given that you have already chosen a diamond $=\frac{13}{51}$
