Answer:

There are six faces for each of two dice, giving 36 possible outcomes. If the two dice are fair, each of 36 outcomes is equally likely.

So far only 3 outcomes sum to 4 which are (1+3), (2+2) and (3+1).

Probability of getting a sum of 4 on one toss of two dice is 3/36, or 1/12.

(note since there isn't a specific # of sides I'm using 6.)

1/12

A gas under 12 pounds per square inch pressure has a volume of 5 liters. What pressure will result in a volume of 4 L?

balu736 [363]

Answer: 15 pounds per inches

Step-by-step explanation:

P1V1 = P2V2

12 ppi × 5L = P2 × 4L

P2 = 12 ppi × 5L / 4L

P2 = 12 ppi × 5 / 4 ( L in denominator is cancelled by L in numerator)

P2 = 3 ppi × 5 ( 12 is cancelled by 4 in denominator)

P2 = 15 ppi

Answer:

$Speed\ of\ car=38\ km/h$

Step-by-step explanation:

Distance Covered by Horse:

$Speed\ of\ horse=50\ km\h=50\times \frac{1000}{60}\ meter/ minute\\\\Speed\ of\ horse=\frac{2500}{3}\ meter/minute\\\\Distance\ covered\ in\ 4\ minutes=speed\times time=\frac{2500}{3}\times 4\\\\Distance\ covered\ in\ 4\ minutes=\frac{10000}{3}\ meters\\\\$

Distance covered by Car:

$Let\ speed\ of\ car=x\ meter/minute\\\\time=4\ minutes\\\\Distance\ covered=speed\times time=4\times x=4x$

$Distance\ covered\ by\ horse=Distance\ covered\ by\ car+800\\\\\frac{10000}{3}=4x+800\\\\4x=\frac{10000}{3}-800\\\\4x=\frac{7600}{3}\\\\x=\frac{7600}{3\times 4}\ meter/minute\\\\x=\frac{7600}{3\times 4}\times \frac{60}{1000}\ km/h\\\\x=38\ km/h$

Goodmorning I need help with this question. And may you explain to me how to get this right step by step. Thank you.

katen-ka-za [31]

Answer:

I think it's "C"

Step-by-step explanation:

Because a function is the independent variable to the dependent variable... Since, the cost relies on the weight, the cost is dependent. While, the weight is independent. I don't know if I'm right, I kinda suck at math
