The question provides the following information;

Money at hand = 73.50

Money earned = x

Purchases made = 99.99

Money left over = 23.51

These sets of numbers can be put into an equation as shown below;

(73.5 + x) - 99.99 = 23.51

This equation means what you had at the beginning plus what earned from mowing lawns is a total of 73.5 + x. Subtract the cost of shoes purchased from this total and you'll now have a balance of 23.51

We can now solve for the money earned from mowing lawns as follows;

(73.5 + x) - 99.99 = 23.51

Add 99.99 to both sides of the equation (in order to isolate the 73.5 + x on the left side of the equation). You now have;

73.5 + x = 123.5

Next you subtract 73.5 from both sides of the equation (in order to isolate the x on the left hand side)

x = 50

This means the money earned from mowing lawns is $50

The graph of the equation and the table is attached below.

Graph:

Graph means the pictorial representation of the given set of data or the equation.

Given,

Here we have the equation

y = -4.

Now, we need to plot the graph for this equation and we have also draw the table for that.

Here we have the equation y = -4. This one can't take any value for the calculation,

Which means it we take any value on the x coordinate, the given equation will result only the value of y as -4.

Which means, if we take x as -2, the value of y is -4.

If we take x as -1, it will also have the value of y as -4.

If we take x as 0, then again we will get the value of y as -4.

Therefore, it will continuous at infinity.

Answer

The sum of the sequence = -30072

Explanation

We are given a sequence of numbers and asked to find the sum of the terms up until the last term given. The sequence given is

9, 4, -1,.............., -546

On careful observation of this sequence, we can see that it is an arithmetic progression with a common difference of -5 between consecutive terms.

Common difference = (n + 1)th term - nth term

= 4 - 9 Or -1 - 4

= -5

For an arithmetic progression, the formula for the last term is given as

Last term = a + (n - 1)d

where

L = last term = -546

a = first term = 9

n = number of terms in the sequence = ?

d = common difference = -5

So, we can solve for the number of terms

-546 = 9 + (n - 1)(-5)

-546 = 9 - 5n + 5

-546 = 14 - 5n

14 - 5n = -546

-5n = -546 - 14

-5n = -560

Divide both sides by -5

(-5n/-5) = (-560/-5)

n = 112

We can now use the formula for the sum of an arithmetic progression to find the sum of this sequence.

We know all of these parameters now

Sum of this AP = (112/2) [(2 × 9) + (112 - 1)(-5)]

= 56 [18 + (111 × -5)]

= 56 [18 - 555]

= 56 [ -537]

= -30072

The final price of gas per gallon after number of reduction and increment is $12.74.

Given,

The price of gas at store = 4.29 per gallon

The increased amount of gas = 0.55

The new price of gas = 4.29 + 0.55 = 4.84 per gallon

Then decreased 0.25. So, the price of gas = 4.84 - 0.25 = 4.59 per gallon

Again the price increases 8.30 and the new price become, 4.59 + 8.30 = 12.89 per gallon

Then, the price of gas finally went down to .15.

Therefore, the price of gas now is:

12.89 - 0.15 = 12.74

That is, the final price of gas per gallon after number of reduction and increment is $12.74.

a. 74.99% probability of getting 746 or more peas with red flowers.

b. Since Z < 2, 746 peas with red flowers is not significantly high.

c. Since 746 peas with red flowers is not a significantly high result, we cannot conclude that the scientist's assumption is wrong.

Given,

953 peas in sample with 746 of them having red flower

Scientist's assumption;

Since there is a 3/4 chance that a pea will have a red blossom, we would anticipate 714.75 (or roughly 715) of the peas to do so; hence, the finding of 746 peas with red flowers is higher than we had anticipated.

Here,

Binomial distribution:

Probability of x successes on n trials, with p probability.

Normal distribution:

In a normal distribution with mean μ and standard deviation σ, the z-score of a measure X is given by:

Z = (X - μ) / σ

If  np ≥ 10 and n (1 - p) ≥ 10 , the binomial distribution can be approximated to the normal with:

μ = np

σ = [tex]\sqrt{np(1-p)}[/tex]

Here,

n = 953 and p = 3/4 = 0.75

Lets see,

μ = np = 953 x 0.75 = 714.75

σ = [tex]\sqrt{np(1-p)}[/tex] = [tex]\sqrt{714.75 . (1 - 0.75)}[/tex] = √714.5 = 26.73

a. The probability of getting 746 or more peas with red flowers.

Using continuity correction, this probability is P(X ≥ 746 - 0.5) = P(X ≥ 745.5) , which is 1 subtracted by the p-value of Z when X = 745.5.

Then:

Z = (X - μ) / σ = (745.5 - 714.75) / 26.73 = 30.75 / 26.73 = 1.150

The p value of z score 1.150 is 0.2501

1 -0.2501 = 0.7499

0.7499 = 74.99% probability of getting 746 or more peas with red flowers.

b. Is 746 red-flowering peas noticeably high

Since Z < 2, 746 peas with red flowers is not significantly high.
