Volgvan3 years ago
8 0

Answer:

1 is 11

3 is 12

5 is the same answer as 3

Step-by-step explanation:

for #1 the angle is 90 degrees and its asking to find x you can set up the equation by sayin 46+4x=90 you substract 46 by 46 and subtract 90 by 46 then you will get 4x=44 dived 4 on each side and you will get x = 11

for #3 the angle is equal to 180 you set up the eqation by saying 36+12x=180 you subtract 36 by itself and 180 by 36 then you will get 144 now your equation is 12x = 144 now divide 12x by  12 and 144 by 12 and you will get x = 12

the weight of an object on mars varies directly as the weight of the object on earth a 90 pound object on earth weighs 34 pounds
Mariulka [41]

We have been given that the weight of an object on the mars varies directly as the weight of the object on earth.  

Let y be weight of an object on Mars and x be weight of an object on Earth.

\\
y=kx

We have been given that the weight of an object on Mars is 34 pounds and weight of the same object on Earth is 90 pounds.

Putting the given values in equation we get

\\
34=k(90)\\
\\
k=\frac{34}{90}=\frac{17}{45}

Therefore, our equation now becomes

\\
y= \frac{17}{45}x

Now we have been given that the weight of an object on Earth is 135 pounds and we have to find the weight of the same object on Mars,

We have been given that \\
x=135

Putting the given values in our equation we get

\\
y= \frac{17}{45}(135)=\frac{17\cdot 135}{45}=17\cdot 3 = 51

Therefore weight of the object on Mars will be 51 pounds.

Brad is looking out his window daydreaming. The number of people who pass by outside his window per hour is a Poisson random var
11Alexandr11 [23.1K]

Answer:

(a) The probability of 7 people passing by the window in the first hour is 0.000034.

(b) The probability of Y = 17 is 0.1144.

(c) The value of E (Y) and V (Y) is 24.

Step-by-step explanation:

Let <em>Y</em> = number of people who passes by Brad's window per hour.

The random variable <em>X</em> follows a Poisson distribution with parameter, <em>λ </em>= 24.

The probability mass function of a Poisson distribution is:

P(Y=y)=\frac{e^{-24}24^{y}}{y!};\ x=0,1,2,...

(a)

Compute the value of P (Y = 7) as follows:

P(Y=7)=\frac{e^{-24}24^{7}}{7!}=\frac{0.17315}{5040} =0.000034

Thus, the probability of 7 people passing by the window in the first hour is 0.000034.

(b)

It is provided that 5 people have already passed by the window in the first 30 minutes.

This implies that in the next 30 minutes 12 people will pass.

The average number of people passing Brad's window in 30 minutes is,\lambda=\frac{24}{2}=12

Compute the probability of Y = 17  as follows:

P (Y = 17) = P (12 people passing in the nest 30 minutes)

=\frac{e^{-12}12^{12}}{12!}=\frac{54782414.52}{479001600} =0.114368\approx0.1144

Thus, the probability of Y = 17 is 0.1144.

(c)

The expected value and variance of a Poisson distribution are same as λ.

So,

E (Y) = 24

V (Y) = 24

Thus, the value of E (Y) and V (Y) is 24.
