Answer:
At an interest rate of 4.5% compounded annually, it will take 16.17 years to reach $17,323.-
Step-by-step explanation:
Giving the following information:
Present Value (PV)= $8,500
Future value (FV)= $17,323
Interest rate (i)= 4.5%
To calculate the time required for the investment to reach the objective, we need to use the following formula:
n= ln(FV/PV) / ln(1+i)
n= ln(17,323/8,500) / ln(1.045)
n= 16.17 years
At an interest rate of 4.5% compounded annually, it will take 16.17 years to reach $17,323.-

Fine the perimeter and the area of this.
Answer:
p = 18 in
a = 25 in²
Step-by-step explanation:
perimeter = sum of the sides
p = 4 1/3 + 5 1/3 + 8 1/3
p = 18 in
Area = 1/2 * base * height
a = 1/2 * 8 1/3 * 6
a = 1/2 * 50
a = 25 in²
Answer:
[tex]p=18\:\mathrm{in},\\A=25\:\mathrm{in^2}[/tex]
Step-by-step explanation:
The area of a triangle is given by [tex]A=\frac{1}{2}\cdot b\cdot h[/tex]. By definition, the base and height must intersect at a [tex]90^{\circ}[/tex] angle.
In this diagram, we notice that the lengths [tex]8\frac{1}{3}[/tex] and [tex]6[/tex] intersect at a [tex]90^{\circ}[/tex], so we can use them as the base and height of the triangle, respectively.
Therefore, the area of the triangle is equal to:
[tex]A=\frac{1}{2}\cdot 6\cdot 8\frac{1}{3}=3\cdot \frac{25}{3}=\boxed{25\:\mathrm{in^2}}[/tex].
The perimeter is simply the sum of all sides of the triangle. Thus, we have:
[tex]p=4\frac{1}{3}+8\frac{1}{3}+5\frac{1}{3}=4+8+5+1=\boxed{18\:\mathrm{in}}[/tex]
A coin is tossed twice. Let Z denote the number of heads on the first toss and W the number of heads on the second toss. If the coin is unbalanced and a head has a 40% chance of occurring, find
Answer:
0.64
Step-by-step explanation:
Prob ( Head ) = 40% = 0.4 , Prob ( Tail ) = 1 - 40% = 60% = 0.6
4 outcomes = (Head Tail) , (Tail Head) , (Head Head) , (Tail , Tail)
Prob (Atleast one head) = Pr (Head Tail) + Pr (Tail Head) + Pr (Head Head)
(0.4) (0.6) + (0.6) (0.4) = 0.24 + 0.24 + 0.16 = 0.64
A chemist mixes 25 milliliters of a solution that is 44% acid with 225 milliliters of pure acid.
(a) How many milliliters of acid are in the resulting
mixture?
milliliters
(b) What percentage of the resulting mixture is acid?
Answer: a) 236 ml b) 94.4 %
Step-by-step explanation: a) in 44 % solution there is 0.44 · 25 ml = 11 ml.
Total volume of acid is 225 ml + 11 ml = 236 ml
b) vol-% of acid is 236 ml /(225 ml + 25 ml) · 100 % = 94.4 %
The milliliters of acid that are in the resulting mixture is 236 millimeters and the percentage of the resulting mixture is acid is 94.4%.
a. The milliliters of acid are in the resulting mixture will be:
= 225 ml + (44% × 25ml)
= 225ml + (0.44 × 25ml)
= 225ml + 11ml
= 236ml
b. The percentage of the resulting mixture that is acid will be:
= [(236ml / (25ml + 225ml)] × 100
= (236ml/250ml) × 100
= 94.4%

Gail works for Ice Cream To-Go. She needs to fill the new chocolate dip cones completely with vanilla ice cream, so that it is level with the top of the cone. Gail knows that the radius of the inside of the cone top is 25 millimeters and the height of the inside of the cone is 129 millimeters.
Using 3.14 for , how much vanilla ice cream will one chocolate dip cone hold when filled to be level with the top of the cone?
Answer:
In other words, they want you to find the volume of the cone.
Volume of a cone=1/3 (pi * radius^2 *h)
Volume=1/3 [3.14* (22)^2 * 120]
Volume=1/3 (3.14*484*120)
Volume=1/3 (182371.2)
Volume= 182371.2/3
Volume=60790.4
The volume of the cone is 60790.4mm^3
But that is not the final answer. Since liquid is measured in litres, You need to convert it to millilitres. So the answer is that one chocolate dip cone can hold a maximum of 60.9704 milliliters

5. Jon Metcalf signed a 253-day simple interest note for $7700 with a bank that uses exact interest. If the rate is 10 3/4% find the maturity value.
Answer:
8281.72
Step-by-step explanation:
Given:
Principal, P = 7700
Rate, r = 10 3/4 % = 43/4 % = 0.1075
Time, t = 253 days = 253/ 360
Using the relation :
A = P(1 + rt)
A = maturity value
A = 7700(1 + 0.1075*253/360)
A = 7700(1 + 0.0755486)
A = 7700(1.0755486)
A = 8281.7243
A = 8281.72

if 2 X + 1 ,2 x-1 and 3 X + 4 are in AP find the value of x
Answer:
x = - 7
Step-by-step explanation:
Given that the terms are in AP , then
a₃ - a₂ = a₂ - a₁ , substitute values
3x + 4 - (2x - 1) = 2x - 1 - (2x + 1) ← distribute and simplify both sides
3x + 4 - 2x + 1 = 2x - 1 - 2x - 1
x + 5 = - 2 ( subtract 5 from both sides )
x = - 7
In a survey of randomly selected 3,900 family-owned businesses with revenues exceeding $1 million a year, it was found that 1,911 of them had no strategic business plan. a) Use a 90% confidence interval to estimate the proportion of family-owned businesses without strategic business plans. Give an interpretation of this interval. (5 Points) b) Would a 99% confidence interval be wider or narrower than the one you calculated in part (a)
Answer:
a) The 90% confidence interval to estimate the proportion of family-owned businesses without strategic business plans is (0.4768, 0.5032). This means that we are 90% sure that the true proportion of all family-owned businesses without strategic business plans is between these two values.
b) Wider
Step-by-step explanation:
Question a:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
In a survey of randomly selected 3,900 family-owned businesses with revenues exceeding $1 million a year, it was found that 1,911 of them had no strategic business plan.
This means that [tex]n = 3900, \pi = \frac{1911}{3900} = 0.49[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.49 - 1.645\sqrt{\frac{0.49*0.51}{3900}} = 0.4768[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.49 + 1.645\sqrt{\frac{0.49*0.51}{3900}} = 0.5032[/tex]
The 90% confidence interval to estimate the proportion of family-owned businesses without strategic business plans is (0.4768, 0.5032). This means that we are 90% sure that the true proportion of all family-owned businesses without strategic business plans is between these two values.
Question b:
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
The higher the confidence level, the higher the value of z, thus the higher the margin of error and the interval is wider. Thus, a 99% confidence interval is wider than a 90% confidence interval.

Step-by-step explanation:
Identify the consequences (i.e., increase, decrease, no change) that the following procedures are likely to have on bias and sampling error in an experimental study. Assigning treatments to subjects alphabetically Increase sample size Calculating power Applying every treatment to every experimental unit in random order Using a sample of convenience instead of a random sample Testing only one treatment group without a control Using a balanced design Informing the human participants of which treatment they will receive
Answer:
A) Bias: Increase
Sampling error: No change
B) Bias: No change
Sampling error: Increase
C) Bias: No change
Sampling error: No change
D) Bias: Increase
Sampling error: No change
E) Bias: Increase
Sampling error: No change
F) Bias: Increase
Sampling error: No change
G) Bias: No change
Sampling error: Decrease
H) Bias: Increase
Sampling error: No change
Step-by-step explanation:
A) Assigning treatments to subjects alphabetically: In this method, treatments are not assigned randomly but alphabetically and thus, it leads to an increase in bias because it's possible that one letter may be favoured over the other. Whereas, sampling error will not change because there's no effect on the sample size.
Thus;
Bias: Increase
Sampling error: No change
B) Increase sample size: In this method, it's only the probability of sampling error that will be increased because the more the sample, the higher the room for error.
Thus;
Bias: No change
Sampling error: Increase.
C) Power is the probability of rejecting the null hypothesis when the alternative hypothesis is true.
Now, this has no effect on the bias or sampling error.
Bias: No change
Sampling error: No change
D) Applying every treatment to every experimental unit in random order: In this there is possibility of an increase in bias because it's possible that some units may or may not have as much treatment as others. But it doesn't affect sampling. Thus;
Bias: Increase
Sampling error: No change
E) Using a sample of convenience instead of a random sample: In this method, there is a high risk of an increase in bias because the sample was selected conveniently instead of randomly. Thus;
Bias: Increase
Sampling error: No change
F) Testing only one treatment group, without a control group; In this method, since there is no control group, there is high probability of an increase in bias but it doesn't affect sampling error.
Thus;
Bias: Increase
Sampling error: No change
G) Using a balanced design; In this method, it means we will not have any bias as the result will be very fair, however it means there would be less of sampling error due to the fair nature of the design. Thus;
Bias: No change
Sampling error: Decrease
H) Informing the human participants of which treatment they will receive; In this method, since the human participants are informed of which treatment they would receive they could alter their responses which would lead to an increase in the bias. Whereas, it would have ko effect on the sampling error. Thus;
Bias: Increase
Sampling error: No change

Answer: B, D, and F
Step-by-step explanation:
Hi, so for this question, the phone bill is in an equation. Before doing this problem, make sure to understand what the 2 and 56 mean. The problem says that c is the monthly charge, and m is the number of minutes. This means that 2 is the number of dollars required to pay when you use the phone for one minute. So 2 dollars per minute. The 56 is basically the fee that is just charged for using the phone bill. Meaning that even if you don't use the phone at all, you will still need to pay 56 dollars.
By understanding those info, it should be easier to answer.
For A, it is not correct. if you look, although 2*4 is 8 dollars, but you need to add 56 for the monthly bill. (I think when they say 'your bill' they mean the monthly bill).
For B, it is correct. Like I said before, the 56 dollars is there no matter how long you use the phone.
For C, it is not correct. This isn't hard to understand since if B is correct, C is probably not, and vise versa. And the 56 dollars is missing.
For D, it is correct. As I said before, the 2 represents the amount of dollars for one minute.
For E, it is not correct. (Contradicts the previous answer and each minute costs 2 dollars).
For F, it is correct. When you use 2 minutes, the equation is 2*2+56 which is 60 dollars.
Hopefully this helps!
