Answer: OPTION A.

Step-by-step explanation:

You have the folllowing fraction given in the problem:

$\frac{5}{7}$

To find an equal fraction, you must multiply the numerator and the denominator by the same number.

OPTION A. The product is obtained by multiplyin 5 by 9 and the produc 63 is obtained by multiplyin 7 by 9. Then, you obtain:

$\frac{5*9}{7*9}$ = $\frac{45}{63}$

The fraction of OPTION B is not obtained by multiplying the numerator and the denominator of originl fraction by the same number.

The fraction of OPTION C is not obtained by multiplying the numerator and the denominator of originl fraction by the same number.

The fraction of OPTION D is not not obtained by multiplying the numerator and the denominator of originl fraction by the same number.

Trey evaluated 12/15 + 1/10 and got the answer of 13/25. which statement is true about this answer?

Ganezh [65]

Answer:

Option C. His answer is not correct, because the same can not be less than either attend

Step-by-step explanation:

we have

$\frac{12}{15}+\frac{1}{10} =\frac{13}{25}$

we know that

$\frac{12}{15}=0.8$

$\frac{1}{10}=0.10$

$\frac{13}{25}=0.52$

substitute

$0.80+0.10=0.52$ ----> is not true

therefore

His answer is not correct, because the same can not be less than either attend

A corporation has 11 manufacturing plants. Of these, seven are domestic and four are outside the United States. Each year a perf

nikdorinn [45]

Answer:

The probability that a performance evaluation will include at least one plant outside the United States is 0.836.

Step-by-step explanation:

Total plants = 11

Domestic plants = 7

Outside the US plants = 4

Suppose X is the number of plants outside the US which are selected for the performance evaluation. We need to compute the probability that at least 1 out of the 4 plants selected are outside the United States i.e. P(X≥1). To compute this, we will use the binomial distribution formula:

P(X=x) = ⁿCₓ pˣ qⁿ⁻ˣ

where n = total no. of trials

x = no. of successful trials

p = probability of success

q = probability of failure

Here we have n=4, p=4/11 and q=7/11

P(X≥1) = 1 - P(X<1)

= 1 - P(X=0)

= 1 - ⁴C₀ * (4/11)⁰ * (7/11)⁴⁻⁰

= 1 - 0.16399

P(X≥1) = 0.836

The probability that a performance evaluation will include at least one plant outside the United States is 0.836.
