Answer:

Step-by-step explanation:

Please, share the possible answer choices next time!

√3*√12 = √36 = ±6

The simplified version of the resulting product is a rational number (±6)

Neither √3 nor √12 by itself is a rational number.

Answer:

$14.\:\:\overline{RT}=3.3\:ft$

Step-by-step explanation:

Using the definition of similar triangle, we have the equation for problem no. 14 as:

$\frac{\overline{QT}}{\overline{RT}}=\frac{\overline{RT}}{\overline{TS}}\\\\\frac{5}{x}=\frac{x}{2.2}\\\\\Rightarrow x=3.3$

Assume a Poisson random variable has a mean of 5 successes over a 125-minute period.

goldenfox [79]

Answer:

$\mu = 25$

$\lambda =0.04$

$P(X > 65 ) =0.0742$

Step-by-step explanation:

From the question we are told that

The number of success is n = 5

The time duration is N = 125 minutes

Generally the mean of the random variable is mathematically represented as

$\mu = \frac{N}{n}$

=> $\mu = \frac{125}{5}$

=> $\mu = 25$

Generally the rate parameter is mathematically represented as

$\lambda = \frac{1}{\mu}$

=> $\lambda = \frac{1}{25}$

=> $\lambda =0.04$

Generally the cumulative distribution function for exponential distribution function is

$F(x) = \left \{0 \ \ \ \ \ \ x \le 0}} \atop {1 -e^{-\lambda t }\ x>0}} \right.$

Generally the probability that the time to success will be more than 63 minutes is mathematically represented as

$P(X > 65 ) = 1 - P(X \le 65)$

Here

$P(X \le 65) = 1 -e^{-65 * \lambda }$

=> $P(X \le 65) = 1 -e^{-65 * 0.04 }$

=> $P(X \le 65) = 0.92573$

$P(X > 65 ) = 1 - 0.92573$

$P(X > 65 ) =0.0742$

Joanne sells silk-screened t-shirts at community festivals and craft fairs. her marginal cost to produce one t-shirt is $ 5.50

Minchanka [31]

A-y=4.50x ,4.50 is the slope because for each shirt she sells that is how much she makes and she doesn't have an original value for a y-intercept.

B- 1 ,each tee-shirt she makes she will profit 4.50 for a single so she makes money after the first one.

C-129 ,because you need to find how much each tee-shirt costs in the bunch of 70 and divide it from 800 and round to 129.
