Complete Question
The projected worth (in millions of dollars) of a large company is modeled by the equation w =256(1.09)^t .
The variable t represents the number of years since 2000. What is the projected annual
percent of growth, and what should the company be worth in 2008?
Answer:
a) The projected annual percent growth = 9%
b) The company's worth in 2008 = 510.09603627(in million dollars) or $510,096,036.27
Step-by-step explanation:
a) The projected annual percent growth
From the formula of company's worth =
w = 256(1.09)^t
1.09 - 1 = 0.09
Converting decimal to percentage
= 0.09 × 100
= 9%
b) The projected worth of the company is represented as:
w= 256(1.09)^t
t = 2000 - 2008 = 8 years
w = 256(1.09)^8
w = 510.09603627(in million dollars)
or 510.09603627 × 1,000,000
= $510,096,036.27

Use a t-test to test the claim about the population mean at the given level of significance using the given sample statistics. Assume the population is normally distributed. Claim: ; Sample statistics: , s, n What are the null and alternative hypotheses? Choose the correct answer below. A. H0: Ha: B. H0: Ha: C. H0: Ha: D. H0: Ha: What is the value of the standardized test statistic? The standardized test statistic is nothing. (Round to two decimal places as needed.) What is the P-value of the test statistic? P-value nothing (Round to three decimal places as needed.)
Complete question is;
Use a t-test to test the claim about the population mean μ at the given level of significance α using the given sample statistics. Assume the population is normally distributed.
Claim: μ ≥ 8300,α= 0.10
Sample statistics: ¯x = 8000, s = 440, n = 24
a. What are the null and alternative hypotheses?
b. What is the value of the standardized test statistic? (Round to 2 decimal places as needed.)
c. What is the p-value? (Round to three decimal places as needed.)
d. Decide whether to reject or fail to reject the null hypothesis.
Answer:
A) Null hypothesis:H0: μ ≥ 8300
Alternative Hypothesis:Ha:μ < 8300
B) t = -3.34
C) p-value = 0.001
D) we will reject the null hypothesis
Step-by-step explanation:
A) We are told that the claim is: μ ≥ 8300. Thus, the null hypothesis would be the claim. So;
Null hypothesis:H0: μ ≥ 8300
Also, alternative hypothesis would be;
Alternative Hypothesis:Ha:μ < 8300
B)Formula for standardized test statistic with a t-test is;
t = (¯x - μ)/√(s/n)
Plugging in the relevant values, we have;
t = (8000 - 8300)/√(440/24)
t = -3.34
C) From online p-value from t-score calculator attached using t = -3.34, n = 24, significance level = 0.01, DF = 24 - 1 = 23 and a one - tailed test, we have;
p-value = 0.001421 ≈ 0.001
D) The p-value of 0.001 is less than the significance value of 0.01,thus we will reject the null hypothesis

how to find amount of ammonia gas in mole if the question gives
- ammonia gas is kept in a 10.0-L tank at 1 atm and 25°C
Answer:
0.409 mol
Step-by-step explanation:
Use ideal gas law:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is universal gas constant,
and T is absolute temperature.
PV = nRT
(1 atm) (10.0 L) = n (0.0821 L·atm/mol/K) (25 + 273) K
n = 0.409 mol
You are offered an investment that pays simple interest and will earn $200 interest on a $2000 investment over 5 years. What interest rate is the investment paying? A) 1.5% B) 2% C) 2.5% D) 3%
Answer:
B) 2%
Step-by-step explanation:
The simple interest formula is ...
I = Prt
Interest I is earned on principal P when it is invested at rate r for t years.
Filling in the given values, we can solve for r:
200 = 2000r(5)
200/10000 = r = 2/100 = 2%
The interest rate is 2%.

if point B is the midpoint of points A and C, find the value of x and AC. AB= 5x - 2, BC= 9x -10
Answer:
AC = 6 ÷ 7
x = 2
Step-by-step explanation:
Given that
AB = 5x - 2
BC = 9x - 10
So,
AC = AB + BC
= 5x - 2 + 9x - 10
14x -12 = 0
AC = 6 ÷ 7
As B is the mid point of point A and point C, so the value of x is determined by solving the given equations mentioned in the question
5x - 2 = 9x - 10
5x - 9x = -10 +2
-4x = -8
x = 2
Hence, the value of AC and the X is 6 ÷ 7 and 2 respectively

The town of Tola has a population of 45,000 and produces 6 tons of garbage each week. Express this information in terms of the function f
Complete question:
The amount of garbage, G produced by a city with population p is given by G = f(p). G is measured in tons per week, and p is measured in thousands of people. The town of Tola has a population of 45,000 and produces 6 tons of garbage each week. Express this information in terms of the function f
Answer:
The information of town Tola can be represented in function as 6 = f(45)
Step-by-step explanation:
Given;
population of Tola, p = 45,000
amount of garbage produced in tons per week, G = 6 tons = 6,000 kg
The function is given by;
G = f(p)
where;
G is the amount of garbage produced in tons per week
p is the population of Tola
Substitute in the given values into the function
6000 = f(45,000)
6 = f(45)
Therefore, the information of town Tola can be represented in function as 6 = f(45)
Using fluorescent imaging techniques, researchers observed that the position of binding sites on HIV peptides is approximately Normally distributed with a mean of 2.45 microns and a standard deviation of 0.35 micron. What position, in microns, are 20% of binding sites greater than
Answer:
2.74 microns
Step-by-step explanation:
According to the given situation, the calculation of position, in microns, is shown below:-
Here we will use the standard normal table,
P(Z > z) = 20%
1 - P(Z < z) = 0.2
P(Z < z) = 1 - 0.2
P(Z < 0.84) = 0.8
after solving the above equation we will get
z = 0.84
Now we will use the z-score formula,
[tex]x = z \times \sigma + \mu[/tex]
[tex]x = 0.84 \times 0.35 + 2.45[/tex]
x = 0.294 + 2.45
= 2.744 microns
or
= 2.74 microns
Josie ate 5/8 of a pie and Marge ate 6/10 of a pie. Who ate more and therefore burped louder?
Josie ate more and burped louder because 5/8 is greater than 6/10 and Josie ate 5/8 of the pie.
Given,
Josie ate 5/8 of a pie and Marge ate 6/10 of a pie.
We need to find who ate more and therefore burped louder.
We need to compare the given fraction and see which is greater.
We have,
Josie = 5/8 of a pie.
Marge = 6/10 of a pie.
Now,
We can compare the fraction in three ways:
Case 1. - In terms of %
5/8 x 100 = 62.5 %
6/10 x 100 = 60%
62.5 % > 60%
5/8 > 6/10
Case 2. - In terms of decimals
5/8 = 0.625
6/10 = 0.6
0.625 > 0.6
5/8 > 6/10
Case 3. -In terms of multiplying
5/8 = 6/10
5 x 10 = 6 x 8
50 = 48
50 > 48
5/8 > 6/10
5/8 is greater than 6/10 so the one who eats 5/8 of the pie ate more and burped louder.
Thus Josie ate more and burped louder.

What would the scatter plot show for data that produce a Pearson correlation of r = +0.88?
a. Points clustered close to a line that slopes up to the right
b. Points clustered close to a line that slopes down to the right
c. Points widely scattered around a line that slopes up to the right
d. Points widely scattered around a line that slopes down to the right
Answer:
The correct option is (a).
Step-by-step explanation:
The Pearson's correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.
Positive correlation is an association amid two variables in which both variables change in the same direction. A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.
Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.
In this case, it is provided that the Pearson correlation coefficient is, r = +0.88.
A correlation coefficient between ±0.70 to ±1.00 are considered as strong positive correlation.
The scatter plot for correlation coefficient between +0.70 to +1.00 shows:
A straight and upward moving trend of the pointA straight line can be formed using these points that slopes up to the rightPoints clustered close to this line that slopes up to the rightThus, the correct option is (a).
