Hi there!

\large\boxed{\text{ UVY} = 65^o, \text{ VYZ }= 65^o}

We can begin by finding ∠VUY so we can solve for ∠UVY.

∠VUY is supplementary to ∠TUY, so:

180 = 144 + ∠VUY

∠VUY = 36°

In a triangle, angles sum up to 180°, so:

180 = 36° + 79° + m∠UVY

m∠UVY = 65°

Solve for m∠VYZ by comparing the angle to m∠UVY because the angles are alternating interior angles. Thus:

m∠UVY = m∠VYZ = 65°.

What is 1 standard deviation on a
PilotLPTM [1.2K]

Answer:

  D. The distance from the mean to an inflection point

Step-by-step explanation:

We rarely encounter the actual formula for the normal PDF. It is ...

  p(x)=\dfrac{1}{\sqrt{2\pi}}e^{-\dfrac{x^2}{2}}

In fact, the inflection points are at x = ±1, where the curve changes from being concave downward to concave upward.

So, one standard deviation is the distance from the mean to an inflection point.

Math Problem( that my teacher didn't even teach me to do!): Akio wants to make a scale drawing that is 1/5 the size of an origin
katrin2010 [14]
<span>You are given a scale down of the original painting into 1/5.  The ship in the original painting is 14 inches. You are required to estimate the size of the ship in Akio’s drawing. All you need to do is to multiply 1/5 by 14.</span>  

(1/5) (14 inches) = 2.8 inches  
<span>Therefore, the scale down of the ship from the original painting is 2.8 inches. </span>

Oil is pumped into a tank at a rate of Q(t)=45-t gallons per minute where time is t is measured in minutes how many gallons are
FinnZ [79.3K]

Answer:

15 gallons

Step-by-step explanation:

Given that:

Pumping rate is modeled by the equation :

Q(t)=45-t gallons per minute ; where t is in minutes

Number of gallons in tank after 30 minutes ;

Q(t)=45-t

Q(30) = 45 - 30

Q(30) = 15

Hence, Number of gallons in tank after 30 minutes is 15 gallons

HELP HELP HELP AND EXPLAIN ANSWERS PLEASE. I U PUT A LINK UR GONNA GET REPORTED

9514 1404 393

Answer:

  2)  (b) -7

  3)  (b) 14

Step-by-step explanation:

2) The sum is found by adding the numbers together. Your calculator can help if you can't do it in your head. I usually find it easier to add the positive and negative numbers separately. Of course the 0 can be ignored.

  18 + 0 -4 -12 +6 -15 = (18 +6) -(4 +12 +15) = 24 -31 = -7

__

3) Apparently, we are to assume that George's percentage will apply to the next 40 pitches. Then ...

  (number missed)/(number thrown) = 35%

  missed = (thrown)×0.35 = 40×0.35 = 14

George is expected to miss 14 of the 40 pitches.
