Based on historical data, your team knows what proportion of the company's number of orders come from Indiana residents. However, your team would like to expand its orders beyond the state of Indiana. By the end of this year, you think you would like your total proportion of orders from Indiana to be between 0.66 and 0.73. If you took a simple random sample of 99 current orders, what is the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73
This question is incomplete, the complete question is;
Based on historical data, your team knows what proportion of the company's number of orders come from Indiana residents.

If you took a simple random sample of 99 current orders, what is the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73
Note: You should carefully round any intermediate calculations to 4 decimal places to match wamap's approach and calculations. After you round to 4 places, use THAT rounded value in later steps. You may need an appropriate population proportion (which you actually found in a previous problem).
Some data:
Total population: 2327
Indiana residents: 1845
Other: 482
Frequency table results for Total Sales:
Count = 2327
Total Sales Frequency
0 to 200 1960
200 to 400 303
400 to 600 53
600 to 800 9
800 to 1000 2
Answer:
The probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73 is 0.0612
Step-by-step explanation:
Given the data in the question;
p" = Indiana residents / Total population
p" = 1845 / 2327
p" = 0.7929
Now, the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73 will be;
P( 0.66 < p < 0.73 ) = P{ [x1 - p" / √( p"(1-p")/n )] < p < [x2 - p" / √( p"(1-p")/n )] }
we substitute
= P{ [0.66 - 0.7929 / √( 0.7929(1-0.7929)/99 )] < p < [0.73 - 0.7929 / √( 0.7929(1-0.7929)/99 )] }
= P{ [-0.1329 / 0.0407] < p < [-0.0629 / 0.0407] }
= P{ -3.2654 < z < -1.5455 }
= ⊕( -1.5455) - ⊕(-3.2654)
from the standard normal table;
= 0.0618 - 0.0006
P( 0.66 < p < 0.73 ) = 0.0612
Therefore, the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73 is 0.0612
A certain department store keeps track of an age and an annual income of customers who have its credit card. From a sample of 820 of such customers the following descriptive statistics had been obtained: the average age was 41 years with the standard deviation of 16 years and the average annual income was $37,290 with the standard deviation of $2,850. The correlation between the age the annual income was found to be 0.34. Answer the following questions. (Round your answers to 2 places after the decimal point).
Calculate the value of a slope.
a) 309.23 $ per year of age
b) 60.56 $ per year of age
c) 192.43$ per year of age
d) None of the above
Answer: b) $60.56 per year of age
Step-by-step explanation: If the scatterplot of two variables shows a line and the correlation between them is strong, we can calculate a regression line.
Regression line is a line graph that best fits the data. Like any other line, its formula is given by
y = mx + b
with
m being the slope
b the y-intercept
The slope of the line, correlation and standard deviations of the two variables have the following relationship:
[tex]m=r\frac{S_{y}}{S_{x}}[/tex]
where
r is correlation
[tex]S_{y}[/tex] is standard deviation for the y data
[tex]S_{x}[/tex] is standard deviation for the x data
For our problem:
r = 0.34
[tex]S_{y}=[/tex] 2850
[tex]S_{x}=[/tex] 16
Calculating
[tex]m=0.34(\frac{2850}{16})[/tex]
m = 60.56
Slope for the regression line of annual income per year of age is 60.56.

In the measurement of the length of a cylinder, the main scale reading of a vernier caliper is 2.8 cm, the vernier reading is 4, and the least count of the vernier is 0.01 cm. Find the reading of the length of the cylinder.
Answer:
the reading of the length of the cylinder is 2.84 cm
Step-by-step explanation:
Given the data in the question;
the main scale reading = 2.8 cm
the Vernier reading = 4
the least count of the Vernier = 0.01 cm
the reading of the length of the cylinder = ?
To determine the reading of the length of the cylinder, we simply say;
Reading length = main scale reading + ( Vernier reading × least count )
so we substitute in our given values
Reading length = 2.8 cm + ( 4 × 0.01 cm )
Reading length = 2.8 cm + 0.04 cm
Reading length = 2.84 cm
Therefore, the reading of the length of the cylinder is 2.84 cm
A player kicks a soccer ball resting on the ground. The height of the ball, h(t), in feet, after t seconds can be represented by the function h(t) =−16t^2+96t. Use this information to answer the two questions that follow:
Part A: What is the total elapsed time, in seconds, from the time the ball is kicked until it reaches ground level again? ____ seconds
Part B: When will the ball reach its maximum height? After _____ seconds.
Answer:
The correct answer is:
Part A: 6 Seconds
Part B: 3 Seconds
Step-by-step explanation:
The given equation is:
⇒ [tex]h(t) =-16t^2+96t[/tex]
Part A:
When h(t) = 0,
⇒ [tex]-16t^2+96t=0[/tex]
On taking "t" as common, we get
⇒ [tex]t(-16t+96)=0[/tex]
⇒ [tex]-16t+96=0[/tex]
On adding "16t" both sides, we get
⇒ [tex]-16t+96+16t=0+16t[/tex]
⇒ [tex]96=16t[/tex]
⇒ [tex]t=\frac{96}{16}[/tex]
⇒ [tex]t=6 \ Seconds[/tex]
Part B:
When [tex]\frac{dh(t)}{dt} =0[/tex]
⇒ [tex]\frac{d}{dt}(-16t^2+96t)=0[/tex]
⇒ [tex]-32t+96=0[/tex]
On adding "32t" both sides, we get
⇒ [tex]-32t+96+32t=0+32t[/tex]
⇒ [tex]96=32t[/tex]
⇒ [tex]t=\frac{96}{32}[/tex]
⇒ [tex]t=3 \ Seconds[/tex]
To make meatloaf. mix 2 pounds of beef and 0.5 of a cup of breadcrumbs. How many pounds of beef
would you mix with 4.5 cups of breadcrumbs
Answer:
18 pounds of beef.
Step-by-step explanation:
For every 0.5 cups of breadcrumbs there's 2 pounds of beef.
0.5 x 9 = 4.5
9 x 2 = 18 or 2 x 9 = 18
multiples of two: 2 4 6 8 10 12 14 16 18
This shows that when we multiply 2 nine times we get 18!

What is the laws of cosines?The law of cosines, commonly referred to as the cosine rule or the cosine formula, in trigonometry essentially connects the length of the triangle to the cosines of one of its angles. It claims that we can determine the length of the third side of a triangle if we know the length of the first two sides and the angle between them.
Given ΔJKL,
j = 7.9 inches, k = 2 inches, l = 9.8 inches
to find the measure of angle K,
we can calculate the angle by cosine law,
cosK = (j² + l² - k²)/(2.j.l)
cosK = (7.9² + 9.8² - 2²)/(2*7.9*9.8)
cosK = 154.45/154.81
K = cos⁻¹(0.99748)
K = 4.067⁰ ≈ 4°
Hence angle K is 4°.
