To answer this question you would start by finding the angle measure of either XYW or ZYV. To do this you would set up the equation 3x+23=7x-37. Start by adding 37 to both sides, getting a new equation of 3x+60=7x. The subtract 3x from both sides, getting 60=4x. Finally, divide both sides by 4, getting x=15. You would then plug 15 in for x in either (3x+23) or (7x-37). I'm using (3x+23). 3(15)+23, multiply 3 by 15, getting 45+23, then add 45 and 23, getting 68 as your angle measure. Finally, subtract 68 from 180 to get your answer, 112.

The function f(x) varies inversely with x and f(x)=2 when x = 16.<br><br> What is f(x) when x = 4?
andrew-mc [135]

Answer: The correct answer is:  [D]:  "8" .

Step-by-step explanation:f y varies inversely with x;  then y = k/x ; with "k" being the "constant" in this equation.  

You can find the constant by substituting the values given: x = 16,  f(x) = y = 2 ;

So, f(x) = y = 2  = k/16 ;

→  2 = k / 16 ;

Solve for the constant; "k" ;

Multiply EACH SIDE of the equation by "16"

→  16* (2) = (k / 16) * 16 ;

→  32 = k ;

 ↔  k = 32 ;  

As such, we can write the equation:

y = k/ x ; as:

→  y = 32/ x ;

Since we are given:  "x = 4" ;  Plug in that value; and solve for "y" ;

y = 32/4 = 8 .

y = 8 .

y = f(x) ;

So;  f(x) = 8 ;  which is:  Answer choice:  [D]:  "8" .

Mekhanik [1.2K]

Answer: 0.8413

Step-by-step explanation:

Given : Henry has collected data to find that the typing speeds for the students in a typing class has a normal distribution.

Mean : \mu=47

Standard deviation : \sigma= 4

Let x be the random variable that represents the typing speeds for the students.

The z-score :-

z=\dfrac{x-\mu}{\sigma}

For x= 51

z=\dfrac{51-47}{4}=1

Using the standard normal distribution table ,the probability that a randomly selected student has a typing speed of less than 51 words per minute :-

P(x

Hence, the probability that a randomly selected student has a typing speed of less than 51 words per minute = 0.8413
