Carlos need to score 95

Step-by-step explanation:

<u>Let the score is x. The average is:</u>

(83 + 56 + 94 + x)/4 = 82
x + 233 = 4*82
x = 328 - 233
x = 95

If Sally can paint a house in 4 hours, and John can paint the same house in 6 hour, how long will it take for both of them to pa

astraxan [27]

Sally can paint a house in 4 hours; Which means in 1 hour she can paint 1/4th of the house.

John can paint the same house in 6 hours. Which means in 1 hour she can paint 1/6th of the house.

Together in 1 hour they can paint: - 1/4 + 1/6 = 5/12th of the house.

Total Hours for painting the house together will be 12/5 = 2.4 Hours.

So the answer is 2 hours and 24 minutes

Suppose cos(O) = 12/13, Quadrant I. Find sin(O).<br> A:13/12<br> B:5/13<br> C:13/5<br> D:5/12

noname [10]

Answer:

B: 5/13

Step-by-step explanation:

pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = 5

sin = opp/hyp

sin 5/13

The volume of soda a dispensing machine pours into a 12-ounce can of soda follows a normal distribution with a mean of 12.30 oun

LiRa [457]

Answer:

The correct answer is "0.9332".

Step-by-step explanation:

Given that:

$\mu=12.30$

$\sigma=0.20$

So,

= $P(X>12)$

= $1-P(X$

= $1-P(\frac{X-\mu}{\sigma} < \frac{12-12.30}{0.20} )$

= $1-P(Z$

= $1-P(Z$

= $1-0.0668$

= $0.9332$
