The rows of small jars of salsa are increased by 4 times.

The rows of ounces of salsa are increased by 32 times.

The pattern in the column of the table is

y = 8x

Therefore x = 4 then y = 8(4) = 32

x = 8 then y = 8(8) = 64

x = 12 then y = 8(12) = 96

x = 16 then y= 8(16) = 128.

x = 20 then y = 8(20) = 160.

The pattern in the column of the table is

y = 8x

Therefore x = 4 then y = 8(4) = 32

x = 8 then y = 8(8) = 64

x = 12 then y = 8(12) = 96

x = 16 then y= 8(16) = 128.

x = 20 then y = 8(20) = 160.

The relationship between ounces of salsa and small jars of salsa using a unit rate is

4 ounces = 1 serving

y = 4x

If x = 1 then y = 4

If x = 2 then y = 4(2) = 8

If x = 3 then y = 4(3) = 12

If x = 4 then y = 4(4) = 16

If x = 5 then y = 4(5) = 20

The relationship using the unit rate is

48 ounces = 4 medium jars of salsa.

For 1 medium jars of salsa = 48/4 = 12 ounces.

1 medium jar of salsa = 12 ounces.

The translation of the given sentence into an equation is: 7(b + 3) = 1.

Variables can be used to represent an unknown quantity when translating statements into equation. The word "times" is represented as or means "×" (multiplication). "Sum" means addition as well.

Thus, the sentence given can be translated as shown below:

The unknown number is represented as variable b.

"The sum of a number (b) and 3" would be translated as: b + 3.

"Seven (7) times the sum of a number and 3 (b + 3)" would therefore be: 7(b + 3).

Therefore, translating the whole sentence into an equation, we would have:

7(b + 3) = 1.

Thus, the translation of the given sentence into an equation is: 7(b + 3) = 1.

The equation in the form y = mx +b, where x is the number of monthly minutes used and y is the total monthly of the A Fee and Fee plan is: y = (3/20)x + 32 and the total monthly cost is $173.75.

a. Equation

Slope = ( $123.5-$86)/(610-360)

Slope=37.5/250

Slope= 3/20

y = mx + b

Solve for "b"

$123.5 = (3/20)610 + b

$123.5  = 91.5 + b

b=$123.5-$91.5

b = 32

Equation:

y = (3/20)x + 32

b. Total cost

Total cost= (3/20)945+32

Total cost= 141.75+32

Total cost= $173.75

Therefore the equation in the form y = mx +b, where x is the number of monthly minutes used and y is the total monthly of the A Fee and Fee plan is: y = (3/20)x + 32 and the total monthly cost is $173.75.

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 %

The area of the given parallelogram is: 9√3 sq. feet.

A parallelogram is a simple quadrilateral with two sets of parallel sides in Euclidean geometry. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

Area of a parallelogram = Base of the Parallelogram * Height

Now, given:

A parallelogram ABCD,

AB = 6 feet, AX = 3√3.   Angle A = 30°

To find: Area of the Parallelogram ABCD.

Finding: Here, AB = 6 feet = base

For height,

Height = perpendicular distance from X to AB

= AX(sinA)

Height = 3√3 (sin30) = 3√3 / 2

Thus, area of the parallelogram = [tex]\frac{3\sqrt{3}}{2}\times6= 9\sqrt{3}sq. feet.[/tex]

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 ).

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).
