I buy a MP3 player for £40 in a sale where it was 20% off. What was the original price

natta225 [31]

20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50

Quick help.<br> Will Mark as Brainliest if my laptop stops acting up.

Vertex is now at (-1,5)

for
y=a(x-h)^2+k
vertex is (h,k)
so veertex is (-1,5)

y=a(x-(-1))^2+5
y=a(x+1)^2+5
a is a constant, we will asssume that it is 1 because all the choices have 1

y=1(x+1)^2+5
y=(x+1)^2+5

2.24 Exit poll: Edison Research gathered exit poll results from several sources for the Wisconsin recall election of Scott Walke

iVinArrow [24]

Answer:

0.4929 = 49.29% probability that he voted in favor of Scott Walker

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)}$

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Having a college degree.

Event B: Voting for Scott Walker.

They found that 57% of the respondents voted in favor of Scott Walker.

This means that $P(B) = 0.57$

Additionally, they estimated that of those who did vote in favor for Scott Walker, 33% had a college degree

This means that $P(A|B) = 0.33$

Probability of having a college degree.

33% of those who voted for Scott Walker(57%).

45% of those who voted against Scott Walker(100 - 57 = 43%). So

$P(A) = 0.33*0.57 + 0.45*0.43 = 0.3816$

What is the probability that he voted in favor of Scott Walker?

$P(B|A) = \frac{0.57*0.33}{0.3816} = 0.4929$

0.4929 = 49.29% probability that he voted in favor of Scott Walker

The table shows the approximate height of an object x seconds after the object was dropped. The function h(x) = –16x2 100 models

gregori [183]

The given model would make the least sense to use for x=-2.75.

the given function is:

$h(x)= -16x^2 +100$

a quadratic relationship,

where

h is the height in feet

x is the time in seconds

<h3>what is kinetic energy?</h3>

Kinetic energy is a form of energy that an object or a particle has by reason of its motion.

as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.

h(-2.75) = $-16*(-2.75)^2+100 = -21\\$

h(0.25) = $-16*0.25^2 +100=99$ $-0.25^2*16+100=99$

h(1.75) = $-16*1.75^2+100=51$

h(25) = $-16*2.25^2+100= 19$

therefore, x=-2.75 this model would make the least sense to use
