Each morning there is a probability of 3/4 that Julie will catch her bus. Over 2 consecutive days, the probability that she will
krek1111 [17]
The probability is 3/16.

The probability that she catches the bus on one of the days is 3/4; the probability she does not on the other day is 1/4.  Together we have
3/4(1/4) = 3/16

Please help I’m confused math is hard!
Butoxors [25]

Answer:

Step-by-step explanation:

basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.

first, you need to factor out the equation.

start with the original equation.

V=4x^3+10x^2+4x

factored form:

V= 2x(2x^2+5x+2)

next, you're going to want to plug in the values.

the answer asks for x=4, but you should do both.

v=2(3)(2(3)^2+5(3)+2)

do not forget to do the exponents before!

v=6(18+15+2)

v=6(35)

v=210 ft^2

that's the answer for if x was equal to 3.

V= 2x(2x^2+5x+2)

<em>don't forget to write the original equation first. </em>

V=2(4)(2(4)^2+5(4)+2)

<em>V=8(36+20+2)</em>

<h2><u><em>V=464 ft^2  </em></u></h2>

⬆is your answer! hope this helped!!

Which equation does NOT represent direct variation? A. Y=x/21 B. y/x=5/8 C. y-3= 3x D. y-5x=0
Serjik [45]
The gradient of the function is constant s the independent variable (x) varies The graph passes through the origin. That is to say when x = 0, y = 0. Clearly A and D pass through the origin, and the gradient is constant because they are linear functions, so they are direct variations. The graph of 1/x does not have a constant gradient, so any stretch of this graph (to y = k/x for some constant k) will similarly not be direct variation. Indeed there is a special name for this function, inverse proportion/variation. It appears both B and C are inverse proportion, however if I interpret B as y = (2/5)x instead, it is actually linear. I believe the answer is C. Hope I helped!
