A. 2(pi) in.
B. 4(pi) in.
C. 16(pi) in.
D. 24(pi) in.

Answer:

-64

Step-by-step explanation:

4 times 10=40

+4times 6=24

Times by -1

=-64

Answer:

36 units

Step-by-step explanation:

3x + 3 + 11 x + 6 = 166  Combine like terms

14x +9 = 166  Subtract 9 from both sides

14x = 157  Divide both sides by 14

x = 11.2142857143  Round to the nearest whole number

x = 11

Now that we know x = 11 we can solve for AG

3x + 3

3(11) + 3

33 + 3

E(HHH)=14; E(H^N)=2 (2N–1).

Let's examine the possibilities for getting three consecutive heads on a fair coin. Let E(HHH) represent the predicted number of flips before three straight heads.

Getting three heads in a row has a 1/8 chance in scenario one. In order to simulate this situation, we would use the formula: (1/8) × 3 = 3/8. This point was reached after three flips.

The first flip is a tails in scenario two. This just increases the expected value of flips by one flip (+1), following the same rationale we used to calculate the expected number of flips with two heads. There is a 50% chance that something will happen. Therefore, we would simulate this event as:

1/2(E(HHH)+1)

Situation 3: The HT sequence appears. Because we should be thinking about occurrences that are mutually exclusive, each of these sequences is distinct from the ones that came before it. With a 1/4 chance of occurring, this particular sequence will increase the estimated number of flips by two. Thus, we would model this situation as follows:

1/4(E(HHH)+2)

Final scenario: Assume that HHT is mentioned. The probability that this particular sequence will occur is 1/8, and it increases the expected number of flips by three (we had the first two heads but then the tails requires us to start over again). Thus, we would model this situation as follows:

1/8(E(HHH)+3)

The total number of potential outcomes at this time is 1 (=(1/8) + (1/2) + (1/4) + (1/8). When we combine all of these possibilities, we get:

E(HHH)=1/8⋅3+1/2⋅(E(HHH)+1)+1/4(E(HHH)+2)+1/8(E(HHH)+3)

As a result, when we solve for E(HHH), we obtain E(HHH)=14.

I'll give a straightforward explanation of how I arrived at the general formula. If we started with just one tails in the prior scenarios, the chance was 1/2 and it would always add 1 to the anticipated number of flips. The chance of a certain sequence would change by an order of (1/2) [independent flips, each element occurring with probability 1/2] each time there was a heads before the tails, and the anticipated number of flips would rise by 1. Finally, if we got all n consecutive heads, that would equal the probability of getting HHH….T (all heads except for the tail at the end). The final word denotes the order of receiving all N heads at once.

Therefore, we can interpret this formula as equal to:

E(HN)=∑(1/2)^i⋅(E(H^N)+i)+(1/2)^N⋅(N) (from i = 1 to N)

This can be condensed to: E(HN)=2 (2N–1).

After a 90° rotation counterclockwise the co-ordinate of the image is

( 7 , - 2 ).

A transformation in which the figure is rotated around a fixed point is called rotation of a graph.

When a given point on a graph is rotated counter clockwise 90° then the co-ordinate of the point will change accordingly.

When A( x , y) is rotated 90° the resulting image will become A'( -y , x ).

∴( - 2 , - 7 ) → ( 7 , - 2 )

Therefore the co-ordinate of the image is ( 7 , - 2 ).

Among the 4,229,138 residents of Indiana aged 25 and older, the percentage of the residents aged 25 and older that have a degree is 31 %.

Percentage, which was adapted from the Latin word "per centum", which means "by the hundred", is a fraction or a ratio in which the value of whole is always 100. It is represented by the symbol "%".

The formula to get the percentage is:

Percentage = (Value / Total Value) × 100

Getting first the total value of the degree holders: 326,036 have an associate's degree, 623,200 have a bachelor's degree, and 348,807 have either a graduate or professional degree

residents with degree = 326,036 + 623,200 + 348,807

residents with degree = 1,298,043

If the total value of the residents aged 25 and older is 4,229,138 and among them, 1,298,043 have a degree, getting its percentage using the formula:

Percentage = (Value / Total Value) × 100

Percentage = (1,298,043 / 4,229,138) × 100

Percentage = (0.3069285041) × 100

Percentage = 30.69 %

Rounding off to the nearest whole number,

Percentage = 31 %

The area of the composite figure is 32 mm²

The area of a composite figure can be found by summing the area of the whole shape.

Therefore, the composite figure is a parallelogram and a triangle.

area of the composite figure = area of the triangle + area of the parallelogram

area of the triangle = 1 / 2 bh

area of the triangle = 1 / 2 × 8 × 2

area of the triangle = 16 / 2

area of the triangle = 8 mm²

area of the parallelogram = bh

area of the parallelogram  = 6 × 4

area of the parallelogram = 24 mm²
