Mathematics

Answer:

See explanation.

Step-by-step explanation:

An expression is a set of terms that are combined using addition, subtraction, multiplication, or division. The following are examples of expressions:

$2x-1$

$5y+8$

$2$

Note: expressions do not equal anything.

In contrast, equations are expressions that equal at least one term. The following are examples of equations:

$2y-4=26$

$4x-4=0$

$x=10$

$y=x+2$

Note: equations do equal a term, as shown in the examples.

The plans were made too hastily, without enough

Talja [164]

The answer is (C). By referring to the plural word "plans" with a plural pronoun ("them"), it avoids the error of the original.

The reason was given for Wrong Answer A: Choice (A) contains an agreement mistake. It is incorrect to use the singular pronoun "it" to refer to the plural noun "plans."

The reason given for Wrong Answer B: In option (B), the alteration is done incorrectly. Hasty should be changed to "hastily" to modify the verb "manufactured."

Justification for Wrong Answer D: Improper alteration is involved in Option (D). Hasty should be changed to "hastily" to modify the verb "manufactured."

Justification for Wrong Answer E: Choice (E) has an agreement mistake. It is incorrect to use the singular pronoun "it" to refer to the plural noun "plans."

On a track and field team, 8% of the members run only long-distance, 32% compete only in field events, and 12% are sprinters onl

kondor19780726 [428]

Answer:

0.40

Step-by-step explanation:

Members who run only long distance = 8%

So, probability that a member will run only long distance = P(A) = 0.08

Members who compete only in field events = 32%

So, probability that a member will compete only in field events = P(B) 0.32

Members who are sprinters = 12%

So, probability that a member is sprinter = P(C) 0.12

We have to calculate the probability that a randomly chosen team member runs only long-distance or competes only in field events. i.e we have to find P(A or B). Since these events cannot occur at the same time, we can write:

P(A or B) = P(A) + P(B)

Using the values, we get:

P(A or B) = 0.08 + 0.32 = 0.40

Thus, the probability that a randomly chosen team member runs only long-distance or competes only in field events is 0.40
