The given geometric series, the first term is a₁ = 2 and the common ratio is r = -1

What are some examples of geometric series?

We are given to find the values of  a₁ and r of the following geometric series

2 - 2 + 2 - 2 + 2 - ........

We know that

a₁ is the first term and r  is the common ratio of the given geometric series.

We can see that the first term of the given geometric series is 2.

So. we must have

            a₁ = 2

Also, common ratio is found by dividing a term by its preceding term.

Therefore, the common ratio r  of the given geometric series is

r = -2/2 = 2 / -2 = ...... = -1

Thus, for the given geometric series, the first term is a₁ = 2 and the common ratio is r = -1.

Carl calculates the z-score corresponding to the weight 255oz= -1.5.

Now, Carl decides to find the percent associated with boxes less then 255 oz, so he rounds to hundred and substract 50% - 7% = 43%.

Given that,

In an orchard, apple weights are typically distributed. Fred the farmer concludes from a sample that the average weight of a box of apples is 270 ounces, with a standard deviation of 10 ounces.

He is interested in knowing what proportion of the apple boxes he has gathered for sale will weigh less than 255 oz.

Mean is 270

Standard deviation is 10

x = 255

Formula for z-score,

z = (x - mean)/SD

z = (255 - 270) / 10

=> z = -15 / 10

=> z = -1.5

Hence, by using z-table,

-1.5 equates to 0.0668, which suggests that 0.07

Therefore, 7% of Apple boxes weigh less than 255 oz.

The ratio of boxes is between 255 oz and 270 oz,

Calculating the proportion

Now,

50% - 7% = 43%.

Therefore, Carl calculates the z-score corresponding to the weight 255oz= -1.5.

Carl decides to find the percent associated with boxes less then 255 oz, so he rounds to hundred and substract 50% - 7% = 43%.

The semester's grade point average for Patty.

The answer to the query is

The student's grade point average is:

multiplying each point by its corresponding credit hour, adding them all up, and then dividing the result by the total amount of credit hours.

Then,

A single point is equal to 5(1) + 3(3) + 1(2) + 5(3), which is 5 + 9 + 2 + 15 = 31.

The numbers outside of the parentheses represent the credit hours while those inside represent the points.

The required value of the standard deviation is 0.04.

Given that,

1 mile ≈ 1.6 kilometers, what is the standard deviation in kilometers is to be determined. Where s = 5

Statistics is the study of mathematics that deals with relations between comprehensive data.

Here,
1 miles = 1.60934 Km
Given
1 mile = 1.6
Standard deviation = 1.60934 - 1.6000
                                = 0.00934
S = 5
Standard deviation = 5 * 0.00934
                                = 0.04670

Thus, the required value of the standard deviation is 0.04.

Answer:

71.62

Step-by-step explanation:

[tex]A = \frac{C^2}{4 \times \pi }\\A = \frac{30^2}{4 \times 3.14 }\\A = 71.62[/tex]

Reason:

32 = 8*4

56 = 8*7

We see that 8 is the largest common factor, aka GCF, of 32 and 56

So this is the greatest number of guests possible.

Each guest will get 32/8 = 4 cookies and 56/8 = 7 slices of pizza.

The set of numbers is S = { x ∈ N ; x > 22 }.

We have the statement:

Set of natural numbers greater than 22.

We need to make the set from it.

A set is a collection of different things objects or elements that are used to represent a situation or a function in a concise form.

For example a set of real numbers can be denoted by x ∈ R.

There can be finite or infinite sets. In finite sets, the number of elements are limited whereas in infinite sets it is not limited.

Here, the set that will be formed can be written as:

S = { x ∈ N ; x > 22 }

The amount taken from Jim's check for FICA taxes is $75.51.

FICA (Federal Insurance Contributions Act) taxes are of two types: Social Security tax and Medicare tax.

FICA taxes simply mean United States federal payroll (or employment) taxes imposed on both employees and employers.  The purpose of FICA taxes is to fund Social Security and Medicare.

These two federal programs benefit retirees, the disabled, and the children of deceased workers.

The rate for the Social Security tax is 6.2% of the taxpayer's gross pay.

The rate for the Medicare tax is 1.45% of the income earner's gross pay.

The FICA taxes rate is 7.65%.

Gross pay for the week = $987

FICA taxes = 7.65%

FICA taxes in dollars = $75.51 ($987 x 7.65%)

Thus, the amount Jim paid in FICA taxes is $75.51.
