Answer:

B. X + 6 = 40

x = 34 students

Step-by-step explanation:

Just do 40 -6 to get 34 students. You can prove your answer is right by doing this:

X + 6 = 40

X + 6 - 6 = 40 -6

X = 34!

Hope this helped! :)

Aleksandr [31]

Answer:

3x + 2 = 50

Step-by-step explanation:

According to the given situation, the equation to determine the number of friends is shown below:-

We assume the number of friends is x

50 - 3x = 2

-3x = -48

3x = 48

x = 16

So, the equation is

3x + 2 = 50

and the number of friends is 16

Therefore, the equation to determine the number of friends we just solved the above equation.

Important Characteristics Quiz The probability of success in each of the 58 identical engine tests is p = 0.92. What is the mean

Maru [420]

Answer: The mean of this binomial distribution is 53.36.

Step-by-step explanation:

We know that , the mean of this binomial distribution is given by :_

$\mu = np$

, where n = sample size or the number of possible trials .

p = probability of getting success in each trial.

We are given that , the probability of success in each of the 58 identical engine tests is p = 0.92.

i.e. n= 58

p=0.92

Then, the mean of this binomial distribution = $58\times0.92=53.36$

Hence , the mean of this binomial distribution is 53.36.

Convert -3pi/10 to degrees

ipn [44]

we know there are 180° in π radians, how many degrees then in -3π/10 radians?

$\bf \begin{array}{ccll} degrees&radians\\ \cline{1-2} 180&\pi \\\\ x&-\frac{3\pi }{10} \end{array}\implies \cfrac{180}{x}=\cfrac{\pi }{~~-\frac{3\pi }{10}~~}\implies \cfrac{180}{x}=\cfrac{\frac{\pi}{1} }{~~-\frac{3\pi }{10}~~} \\\\\\ \cfrac{180}{x}=\cfrac{\pi }{1}\cdot \cfrac{10}{-3\pi }\implies \cfrac{180}{x}=-\cfrac{10}{3}\implies 540=-10x\implies \cfrac{540}{-10}=x \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill -54=x~\hfill$
