Answer:

a ( copper and nickel

b ( 1034.9

Step-by-step explanation:

Add all the values of melting points

2,651 + -37.89 = 2613.11

2613 + -458 = 2155.11

2155.11 + 1984.32 = 4139.43

Divide the number by the number of numbers: 4139.43/4 = 1034.8575

1034.8575 rounded to the nearest tenth is 1034.9, thats how you find the mean, or the average.

The admissions office of a private university released the following admission data for the preceding academic year: From a pool

lina2011 [118]

Answer: Our required probability is 0.1695.

Step-by-step explanation:

Since we have given that

Number of male applicants = 4200

Number of female applicants = 3800

So, total number of applicants = 4200+3800 = 8000

Probability of male entered and subsequently enrolled is given by

$0.4\times 0.4=0.16$

Probability of female entered and subsequently enrolled is given by

$0.4\times 0.45\\\\=0.18$

Number of male entered and subsequently enrolled is given by

$0.16\times 4200\\\\=672$

Number of female entered and subsequently enrolled is given by

$0.18\times 3800\\\\=684$

So, Probability that a student who applied for admission will be accepted by the university and subsequently will enroll is given by

$\dfrac{672+684}{8000}\\\\=\dfrac{1356}{8000}\\\\=0.1695$

Hence, our required probability is 0.1695.
