Which expression can go in the blank to make the equation true? 60 – 31.2 + ? = 0 a. 60 – 31.2 b. -60 + (-31.2) c. 31.2 - 60 d.

Ne4ueva [31]

Answer:

Step-by-step explanation:

Given that

60 – 31.2 + ? = 0

$\Rightarrow ?=31.2-60$

This is the same as the expression in option (c) 31.2-60.

Hence, option (c) is correct.

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

Solve the system of equations by substitution. X + y = 32 y = 7x The solution of the system is (Simplify your answer. Type an or

sweet-ann [11.9K]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

The given equations are :

$\qquad \sf \dashrightarrow \:x + y = 32$

and

$\qquad \sf \dashrightarrow \:y = 7x$

Now, plug in the value of y from equation 2 into equation 1 to find out the value of x ~

$\qquad \sf \dashrightarrow \:x + y = 32$

$\qquad \sf \dashrightarrow \:x + 7x = 32$

$\qquad \sf \dashrightarrow \:8x = 32$

$\qquad \sf \dashrightarrow \:x = 32 \div 8$

$\qquad \sf \dashrightarrow \:x = 4$

Now, plug the value of x in equation 2 to find y

$\qquad \sf \dashrightarrow \:y = 7x$

$\qquad \sf \dashrightarrow \:y = 7 \times 4$

$\qquad \sf \dashrightarrow \:y = 28$
