1 answer:

8 0

59 is a rational number
59 is not a irrational number because simply a irrational number is basically
Pi ,E
Or any imperfect squares
A irrational number is a non repeating decimal and has different numbers in each space

Elis [28]

Answer:

0.9783 = 97.83% probability that a can that gets shipped for use will be of perfect shape

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

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

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Shipped for use

Event B: Perfect shape

Probability of being shipped for use:

Perfect shape(0.9 probability) or unnoticeable dent(0.02 probability). So

$P(A) = 0.9 + 0.02 = 0.92$

Being shipped for use and being in perfect shape.

0.9 probability, so $P(A \cap B) = 0.9$

What is the probability that a can that gets shipped for use will be of perfect shape?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.9}{0.92} = 0.9783$

0.9783 = 97.83% probability that a can that gets shipped for use will be of perfect shape

PLEASE HELP ME WITH THIS

NeX [460]

In this question , we have to use sine law, which is

$\frac{sin \ Q}{PR} = \frac{sin \ P}{QR}$

$\frac{sin73}{68} = \frac{sin \ P }{47.6}$

$sin \ P = \frac{47.6 sin 73}{68}$

$P = sin^{-1} ( \frac{ 47.6 sin73}{68}) = 42$

Correct option is b.

If you multiply a value x by -2 and the product is -14, what sign is the value of x? Explain.

Savatey [412]

The sign of the value of x is positive.

The equation is $\frac{y}{3} = -6$ where $y = -18.$

Step-by-step explanation:

Step 1:

If two positive or negative values are multiplied the resulting number would be positive. Whereas, if two values with different symbols are multiplied, the resulting value will be negative.

$(x) (-2) = -14, x = \frac{-14}{-2} = 7.$

If -2 is multiplied with x and the resulting value is -14, the value of x is positive. the value of x is 7.

Step 2:

Assume the amount is y. If y is divided into three equal groups, there would be three groups of 6.

So $\frac{y}{3} = -6, y = (-6)(3) = -18.$

So there were -18 units to start with which was divided into 3 groups of -6 each.
