loris [4]

Answer:

(1,2.16), (2,4.32) and (3, 6.48).

The solution (1,2.16) means that 1 cubic units of pudding weighs 2.16 pounds.

The solution (2,4.32) means that 2 cubic units of pudding weighs 4.32 lbs.

Step-by-step explanation:

The equation y=2.16x describes the weight y of x cubic pounds of pudding.

The three solutions of this equation are (1,2.16), (2,4.32) and (3, 6.48).

Now, solution (1,2.16) means that 1 cubic unit of pudding weighs 2.16 pounds.

Again, solution (2,4.32) means that 2 cubic units of pudding weigh 4.32 lbs. (Answer)

Are collinear points coplanar?

Anna35 [415]

collinear points are points in the same line, like

●-----------------●------------------------------------------●

and the line will always be contained by a plane, so since the line is in a plane, all points in it will also be in the same plane, and therefore be coplanar.

Find the probability of at least one

zmey [24]

Answer:

99.8% probability of at least one failure.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

Probability of success is 30%.

This means that $p = 0.3$

Five trials:

This means that $n = 5$

Find the probability of at least one failure in five trials of a binomial experiment in which the probability of success is 30%.

Less than five sucesses, which is:

$P(X < 5) = 1 - P(X = 5)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 5) = C_{5,5}.(0.3)^{5}.(0.7)^{0} = 0.002$

$P(X < 5) = 1 - P(X = 5) = 1 - 0.002 = 0.998$

0.998*100% = 99.8%

99.8% probability of at least one failure.
