0 read operations and fails 4 times, the empirical probability that a CD drive will fail is %. If the theoretical model is valid, the company would expect the empirical probability to decrease as the number of read operations .

Answer:

Let P= error

n = number of operations

P = .016

n = 250

Multiply P and n

.016 (250) = 4

The number of times it may fail is 4.

What is the midpoint of h(7,10),x(5,-8)
Scorpion4ik [409]
See attachment

then we add 7 and 5 and divide that by 2, which gives you 6 (x-coordinate)
and add 10 and -8 and divide that by 2, which gives you 1 (y-coordinate)

the answer is (6, 1)

justification
so midpoint is basically the middle point of 2 points
that's why we have to add the two x coordinates first then divide it by 2
                               or add the two y coordinates then divide it by 2

What is the 37th term of the arithmetic sequence with the first term -39 and the common difference of 8.
Mrrafil [7]

Answer:

a_{37}=249

Step-by-step explanation:

A sequence that has a common difference is an <em>arithmetic sequence</em>:

a_n=a_1+(n-1)d

where aₙ is the nth term, n is the index, and d is the common difference.

In your question:

  • n = 37
  • a₁ = -39
  • d = 8

Plug those into the formula:

a_{37}=-39+(37-1)8

Then solve:

a_{37}=-39+(36)8\\a_{37}=-39+288\\a_{37}=249
