Answer:
Shape of sampling distribution of sample mean being approx normal or not depends upon sample size.
Step-by-step explanation:
'The shape of the sampling distribution of the sample mean is approximately normal' might be true or false, depending on sample size.
If the sample size satisfies the condition of being sufficiently large, the shape of sampling distribution of sample mean becomes more bell shaped normally distributed (even more normally distributed than actual population).
Central Limit theorem also states this - Larger the sample size, shape of sampling distribution of sample mean becomes more normally distributed around population mean.

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
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
Convert 26.7% to an
equivalent decimal.
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.

Answer:
x i a 90 degree anglt
Step-by-step explanation:
Answer:
80
Step-by-step explanation:
Sum of all angles = 360°
85° + x + 35° + 2x = 360°
3x + 120° = 360°
3x = 360° - 120°
3x = 240°
x = 80°

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
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.

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
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.

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