Convert 26.7% to an
equivalent decimal.

Answers

Answer: 26.7

First, you must remove the percentage sign, then you will get a equivalent decimal.

When we remove the % sign, we get 26.7.

The answer is 26.7. Hope this helps!

It is found that 26.7% as an equivalent decimal is 0.267.

LEt the value of which a thing is expressed in percentage is "a' so the percent that considered thing is of "a" is b%

However percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

To convert 26.7% to an equivalent decimal, we simply divide it by 100:

26.7% ÷ 100

26.7/ 100 x 100 = 0.267

Therefore, WE can conclude that 26.7% as an equivalent decimal is 0.267.

Fill in the blank. The critical value tα/2 that corresponds to a ________% confidence level with 1000 degrees of freedom is 2.33.

Answers

Answer:

The critical value tα/2 that corresponds to a 98% confidence level with 1000 degrees of freedom is 2.33.

Step-by-step explanation:

From the question we are told that

The critical value is [tex]t_{\frac{\alpha }{2} } = 2.33[/tex]

From the student's t distribution table the probability of [tex]( t > 2.33)[/tex] at a degree of freedom of 1000 is

[tex]\frac{\alpha }{2} = (t > 2.33 ) = 0.01[/tex]

Hence the level of significance is mathematically evaluated as

[tex]\alpha = 2 * 0.01[/tex]

=> [tex]\alpha = 0.02[/tex]

Generally the confidence level is mathematically represented as

[tex]C = 1- \alpha[/tex]

=> [tex]C = 1- 0.02[/tex]

=> [tex]C = 0.98[/tex]

Converting to percentage

=> [tex]C = 0.98 * 100[/tex]

=> [tex]C = 98\%[/tex]

parallelogram ABCD has the following vertices A(0,8) B(8,4) C(2,-8) D(-6,-4) is parallelogram ABCD a rectangle, and why

Answers

Answer:

Yes, because BC is perpendicular to AB, and ABCD is a parallelgram.

Yes the parallelogram is a rectangle.

What is distance formula?

The distance between coordinate P(x1 , y1) and coordinate Q(x2 , y2) is calculated using the distance formula: d = √[(x2 - x1)² + (y2 - y1)²]

Given:

ABCD is parallelogram, so its opposite sides are equal in length.

i.e., AB= CD and AD= BC

Now,

d=√(8−0)²+(4−8)

d=√(8)²+(−4)²

d=√64+16

d=√80

d=√(−6−2)²+(−4−(−8))²

d=√(−8)²+(4)²

d=√64+16

d=√80

so, AB = CD

Similarly, AD= BC = √180

Hence, a quadrilateral whose opposite side are equal called as rectangle.

A student has started a lawn care business. He charges $15 per hour to mow lawns and $20 per
hour for gardening. Because he is still in school, he is only allowed to work for at most 20 hours per
week. His goal is to make at least $300 per week.
1. Create a system of equations or inequalities that models the situation. Define the variable you use

Answers

Answer:

15x20/300

Step-by-step explanation:

you multiply 15 and 20 then didvide that answer to 300

These are the points (20,0), (0,20), (20,5) are a few points which represent the number of hours a student can work each job to meet his goal.

Let ;

The hour spent in mow lawns is represent by x,

And represent the hour spent for gardening by y.

According to the question;

He charges $15 per hour to work mow lawns .

And $20 per hour to gardening .

Total no. of hours allowed to work = 20 hours per week

Then the inequality to represent the cost constraint will be,

15x+20y ≥ 300

Since,

He cannot work for more than 15 hours per week, the inequality to represent the time constraint will be,

x + y ≤ 20

On solving the inequalities,

15(20-y) + 20y = 300

300 - 15y + 20y = 300

5y= 0

y = 0

For value of x put y = 0

x + 0 = 20

It states if he work only in mows law for 20 hours he can earn $15 =(15)(20) =$300

All pairs of positive numbers whose sum is less than 20, are solutions to the given system of inequalities.

A pair of negative numbers will also solve both constraints, but is not applicable in this situation because a student, cannot work for negative hours, or for a negative amount of money.

So, (20,0), (0,20), (20,5) are a few points which represent the number of hours a student can work each job to meet his goal.

A man earned wages of $36,300, received $2200 in interest from a savings account, and contributed $2700 to a tax-deferred retirement plan. He was entitled to a personal exemption of $4050 and a standard deduction of S6300. The interest on his home mortgage was $7800, he contributed $2900 to charity, and he paid $1750 in

state taxes. Find his gross income, adjusted gross income, and taxable income Base the taxable income on the greater of a standard deduction or an itemized

deduction

Answers

Answer:

Gross income = $38500

Adjusted gross income = $35800

Taxable income = $13000

Step-by-step explanation:

1. Gross income = wages + interest received

Gross income = $36,300 + $2200

Gross income = $38500

2. Adjusted gross income = Gross income - adjustments

Adjusted gross income = $38500 - $2700

Adjusted gross income = $35800

3. Taxable income = adjusted income - (exemption + deductions)

Taxable income = $35800 - ($4050 + $6300 + $7800 + $2900 + $1750)

Taxable income = $35800 - $22800

Taxable income = $13000
