Answer: The sequence does not have common ratio.

Step-by-step explanation:

By definition, a sequence with a constant ratio (common ratio) between terms is called a "Geometric sequence". In order to find the common ratio, it is necessary to divide any term in the sequence by the previous term.

In this case, given the sequence:

2,4,8,-16, 32, 64,

We get:

4\div2=2\\\\8\div4=2\\\\-16\div8=-2\\\\32\div(-16)=-2\\\\64\div32=2

Since the ratios between the terms are not constant, we can conclude that <em>the sequence does not have common ratio.</em>

A part selected for testing is equally likely to have been produced on any one of six cutting tools.
JulijaS [17]

Answer:

a)S= (1,2,3,4,5,6)

b) 1/6 or 16.67%

c) 1/3 or 33.33%

d) 5/6 or 83.33%

Step-by-step explanation:

a) Sample space is the list of all the possible sample in this its either tool 1,2,3,4,5 or 6

b) probability of selecting from tool 1 is equally likely to picking from any cutting tool therefore it

1/6 or 16.7%

c) probability of selecting from any tool is 16.7% so probability of selecting from 3 or 5 = 16.67% + 16.67% = 33.3%

d) if the part is not from tool 4 then its from tool 1, or tool 2 or tool 3 or tool 5 or tool 6 therefore its

1/6+1/6+1/6+1/6+1/6 = 5/6 or 8.33%

What is the surface area of a cone that has a radius of 8 feet and a slant height of 12 feet? (Use 3.14 for π.)
kodGreya [7K]

Answer:

Surface area of cone is 502.4\ ft^2

Step-by-step explanation:

Given:

radius of a cone (r) = 8 feet

slant height of cone (l) = 12 feet

We need to find the surface area of cone.

Total surface area of cone = Area of circle + Area of curved surface

Now we know that,

Area of circle = \pi r^2

Area of curved surface = \pi rl

Hence Total surface area of cone = \pi r^2+\pi rl=\pi r(r+l) = 3.14 \times 8 (8+12)=3.14\times8\times20= 502.4 \ ft^2

Surface area of cone is 502.4\ ft^2.

Solve for the value of v.
DanielleElmas [232]

Answer:

V=14

Step-by-step explanation:

Well its a supplementary angle if you add everything together.

We know theres a 90 degrees angle and a 34 degree angle.

90+34=124

124+4v=180

Since if you add everything up its a straight line

Solve the equation normally

56=4v

14=v
