A home business has an average income of $900.00 per month with a standard deviation of $15.00 if the income given month is $930.00 what z-score corresponds to this value
Answer:
Z score is a statistical that corresponds to the standarization of the regular score to a normal dsitribution
The formula for Z score is Z = [X - mean ]./ (standar deviation)
Here X = 930.00; mean = 900.00; and standard deviation = 15.00
Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00
Answer: 2.00

A fashion designer wants to know how many new dresses women buy each year. A sample of 683 women was taken to study their purchasing habits. Construct the 95% confidence interval for the mean number of dresses purchased each year if the sample mean was found to be 4.6. Assume that the population standard deviation is 2. Round your answers to one decimal place.
The required confidence interval is (5.5<<5.7) for the mean number of dresses purchased each year.
As per the question, the given data as
[tex]\bar{x}[/tex] = 5.6
σ = 1.3
n = 650
The Z-critical value at the 95% confidence level is 1.960.
To determine the 99% confidence interval for the mean number of dresses purchased each year.
95% CI = [tex]\bar{x}[/tex] ± Z(Cr)(s/√n)
⇒ -5.6 ± 1.960(1.3/√650)
⇒ 5.6±0.100
⇒ (5.500,5.700)
Round to near 1 decimal place
⇒ (5.5,5.7)
Therefore, the required confidence interval is (5.5<<5.7)

Find the value of f(4) for the function
Answer:
f(4) = 7
Step-by-step explanation:
The notation for these type of problems is very confusing. Just remember that f(x) is the same thing as y (or some variable). Even if there is a number or something on the inside of the parentheses, it's still just a variable.
In our case
f(a) = 2(a + 4) -9
could be rewritten as
y = 2(a + 4) - 9
the thing on the inside of the parentheses signifies what the equation is dependent on.
so when is says f(4), it just want's you to trade out a for a 4, but the equation is still the same.
f(4) = 2((4) + 4) - 9
Now, just follow the order of operations
f(4) = 2(8) - 9
f(4) = 16 - 9
f(4) = 7

Convert 38,338,856 seconds to days. Round to 1 decimal.
Answer:
443.736759 day
Step-by-step explanation:
To convert a seconds to days, divide the time by the conversion ratio.
So.....
One day is equal to 86,400 seconds, you can use this formula to convert:
days = seconds ÷ 86,400
The time in days is equal to the seconds divided by 86,400.
Example: Convert 50,000 seconds to days (use the formula above)
50,000 sec = (50,000 ÷ 86,400) = 0.578704 day
Select all the roots of the following equation.
Solve (x−5)(x+9)=0
Select 2 correct answer(s)
14
5
-9
5
9
-14
Answer:
5, -9
Step-by-step explanation:
(x - 5)(x + 9) = 0 These are factors, to get the roots, just set each one equal to zero
x - 5 = 0
x = 5
x + 9 = 0
x = -9
Answer:
Postive 5 and negative 9.
Step-by-step explanation:
So remember, all we have to do is set each of the parethese to zero and solve. It should look like this:
x-5=0 and x+9=0
For the first equation we have made, jsut add 5 to both sides so x is alone. This will get you:
x=5
So the first answer for x is 5.
Now lets solve our second equation and find the second answer for x.
So all we have to do for this one is subtract 9 from both sides. This should get you:
x=-9
So now we know that our two answers for x is 5 and -9.
These two answers seem to be on your list as #2 answer and #3 answer.

Answer:
7)Bagel costs $3.5 and muffin cost $1.25
8) Ticket is $9 while snacks are $2
9) Correct because left hand side is zero
10) Correct because they both have same slope and same y-intercept
Step-by-step explanation:
7) Let bagel be x and muffin be y.
Thus;
For Aaron;
x + 3y = 7.25 - - - (1)
For bee;
x + 2y = 6 - - - (2)
Subtract eq 2 from eq 1 to get;
y = 1.25
Put 1.25 for y in eq 2;
x + 2(1.25) = 6
x + 2.5 = 6
x = 6 - 2.5
x = 3.5
Bagel costs $3.5 and muffin cost $1.25
8) Let movie ticket be x and snacks be y.
Thus;
2x + 3y = 24 - - - (1)
3x + 4y = 35 - - - (2)
Multiply eq(1) by 3 and eq(2) by 2 to get;
6x + 9y = 72 - - - (3)
6x + 8y = 70 - - - (4)
Subtract eq 4 from eq 3 to get;
y = 2
Put 2 for y in eq 3;
6x + 9(2) = 72
6x + 18 = 72
6x = 72 - 18
6x = 54
x = 54/6
x = 9
Ticket is $9 while snacks are $2
9) using elimination, subtract eq 1 from eq 2, we will see that the entire left hand side is equal to zero.
Thus, no solution exists because we can't isolate the variable to get an answer.
10) The answer is correct because for a system of 2 simultaneous equations to have infinite solutions, they both have to have the same y-intercept and also same slope.
In this case, their y-intercept which is when x is 0 is;
3(0) + y = 9
y = 9
Their slope is also the same equal to 3.

Answer:
30 ft is the answer.
Step-by-step explanation:
a = 24 ft
b = 18 ft
c = ?
According to the Pythagoras theorem,
a² + b² = c²
24² + 18² = c²
576 + 324 = c²
c² = 900
c = 30 ft
∴ The opposite corners of the living room are 30 ft apart.
Find the present worth ofRS.2040 due 4 years hence reckoning interest at 5%p.a.
Answer: 408
Step-by-step explanation:
The present worth of Rs 2040 is due 4 years hence reckoning interest at 5% per annum will be Rs 2448.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.
Simple interest has a constant principal amount, as opposed to compound interest, which multiplies the interest from the principal of previous years to calculate the interest of the subsequent year.
Given,
Principle amount = Rs 2040
Time period = 4 years
Rate of interest = 5 %
Simple interest = PRT/100
Simple interest = 2040 × 5 × 4/100 = Rs408
Present worth = Principle amount + Interest
Present worth = 2040 + 408
Present worth = Rs 2448.
Hence present worth of the amount of Rs2040 in 4 years will be Rs 2448.

Please the the working. A car bought for $200 and sold for $250, what was the percentage gain of the cost price?
9514 1404 393
Answer:
25%
Step-by-step explanation:
A percentage change is calculated using the formula ...
pct change = ((new value) - (old value))/(old value) × 100%
For your numbers, this is ...
pct change = (250 -200)/200 × 100% = 50/200×100% = 25%
The selling price was 25% more than the cost price.
