Answer:

Step-by-step explanation:

The number of defective laptops = 6/145 * 100 as a percent.

The number of defective laptops = 4.13% in a sample of 145

A: False. The percentage should be the same for 290 laptops. The % does not change. The number of defective laptops will change (12)

B: True. It is a reason assertion that about 4% of all laptops will be defective.

C: True. It is not reasonable to assume that only 0.5 laptops will be defective. .5% is too small.

D: True. 10% is too high.

E: False. The variation should not be much.

If a is the average (arithmetic mean) of 4x and 7, b is the average of 5x and 6, and c is the average of 3x and 11, what is the
Debora [2.8K]

Answer:

2x+4

Step-by-step explanation:

Given that a is the average (arithmetic mean) of 4x and 7, b is the average of 5x and 6, and c is the average of 3x and 11

By definition of arithmetic mean,

we have a=\frac{4x+7}{2} \\b=\frac{5x+6}{2} \\c=\frac{3x+11}{2}

Let us calculate sum of a,b,c in terms of x

a+b+c = \frac{4x+7+5x+6+3x+11}{2} \\=6x+12

Average = sum/3 = \frac{6x+12}{3} =2x+4

The quadratic function f(x) has a vertex at (9, 8) and opens upward. If g(x) = 4(x − 8)2 + 9, which statement is true?
IrinaVladis [17]
G(x) would involve a translation left 1 and up 1.

g(x) is written in vertex form, which is

g(x) = a(x-h)²+k, where (h, k) is the vertex.  Since
g(x) = 4(x-8)²+9, the vertex is at (8, 9).  Comparing this to the vertex of f(x), which is at (9, 8), it is left 1 and up 1.
