madreJ [45]

Answer: 2:3.

Step-by-step explanation:

$\displaystyle\\\frac{The\ height\ of\ a\ model \ of \ a\ famous \ statue }{The\ height\ of\ the\ actual \ statue} =\frac{2\frac{1}{2} }{3\frac{3}{4} } \\\\\frac{\frac{5}{2} }{\frac{15}{4} } =\\\\\frac{5*4}{15*2} =\\\\\frac{2}{3}=2:3.$

Answer:

m < -18/19

Step-by-step explanation:

8m + 95 < -87 m +5

Add 87m to each side

8m+87m + 95 < -87 m+87m +5

95m + 95 < 5

Subtract 95 from each side

95m + 95-95 < 5-95

95m < -90

Divide each side by 95

95m/95 < -90/95

m < -18/19

In a given region, the number of tornadoes in a one-week period is modeled by a Poisson distribution with mean 2. The numbers of

klio [65]

Answer:

0.1512 = 15.12% probability that fewer than four tornadoes occur in a three-week period.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

In a given region, the number of tornadoes in a one-week period is modeled by a Poisson distribution with mean 2

Three weeks, so $\mu = 2*3 = 6$

Calculate the probability that fewer than four tornadoes occur in a three-week period.

This is:

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

In which

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-6}*6^{0}}{(0)!} = 0.0025$

$P(X = 1) = \frac{e^{-6}*6^{1}}{(1)!} = 0.0149$

$P(X = 2) = \frac{e^{-6}*6^{2}}{(2)!} = 0.0446$

$P(X = 3) = \frac{e^{-6}*6^{3}}{(3)!} = 0.0892$

Then

$P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0025 + 0.0149 + 0.0446 + 0.0892 = 0.1512$

0.1512 = 15.12% probability that fewer than four tornadoes occur in a three-week period.

C subtracted from the sum of x and y

Rashid [163]

Answer:

c - (x + y)

Step-by-step explanation:

c subtracted from the sum of x and y

sum means total in addition

so the subtraction would come second

to show priority, use parenthesis

c - (x + y)
