Mrs. Stevens deposited $4,500 in a college savings account for her grandson that earns an annual simple interest rate of 6.5%. How much interest will be paid in 10 years?
The interest that will be paid in 10 years is = $2,925
The total amount of money deposited as savings (p)

The annual simple interest rate (r) = 6.5%.
The time to collect the interest expected (t) = 10 years.
There the simple interest generated =

An advertisement for a popular weight-loss clinic suggests that participants in its new diet program lose, on average, more than 10 pounds. A consumer activist decides to test the authenticity of the claim. She follows the progress of 18 women who recently joined the weight-reduction program. She calculates the mean weight loss of these participants as 10.8 pounds with a standard deviation of 2.4 pounds. It may be assumed that the weight loss of participants to the weight-reduction program is normally distributed.
a) set up the competing hypotheses to test the advertisement's claim
b) at the 5% significance level, what is the critical value(s)? specify the decision rule
c) what does the consumer activist conclude?
Testing the hypothesis, it is found that:
a)
The null hypothesis is: [tex]H_0: \mu \leq 10[/tex]
The alternative hypothesis is: [tex]H_1: \mu > 10[/tex]
b)
The critical value is: [tex]t_c = 1.74[/tex]
The decision rule is:
If t < 1.74, we do not reject the null hypothesis.If t > 1.74, we reject the null hypothesis.c)
Since t = 1.41 < 1.74, we do not reject the null hypothesis, that is, it cannot be concluded that the mean weight loss is of more than 10 pounds.
Item a:
At the null hypothesis, it is tested if the mean loss is of at most 10 pounds, that is:
[tex]H_0: \mu \leq 10[/tex]
At the alternative hypothesis, it is tested if the mean loss is of more than 10 pounds, that is:
[tex]H_1: \mu > 10[/tex]
Item b:
We are having a right-tailed test, as we are testing if the mean is more than a value, with a significance level of 0.05 and 18 - 1 = 17 df.
Hence, using a calculator for the t-distribution, the critical value is: [tex]t_c = 1.74[/tex].
Hence, the decision rule is:
If t < 1.74, we do not reject the null hypothesis.If t > 1.74, we reject the null hypothesis.Item c:
We have the standard deviation for the sample, hence the t-distribution is used. The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean. [tex]\mu[/tex] is the value tested at the null hypothesis. s is the standard deviation of the sample. n is the sample size.For this problem, we have that:
[tex]\overline{x} = 10.8, \mu = 10, s = 2.4, n = 18[/tex]
Thus, the value of the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{10.8 - 10}{\frac{2.4}{\sqrt{18}}}[/tex]
[tex]t = 1.41[/tex]
Since t = 1.41 < 1.74, we do not reject the null hypothesis, that is, it cannot be concluded that the mean weight loss is of more than 10 pounds.

Given that, Kathy is baking 3 apple pies. Each pie requires 2 3/4 pounds of apples. Apples cost $2.49 a pound.
We need to find out how much will Kathy spend on apples.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the amount spent on apples be x.
Now, 2 3/4=11/4
The total number of apples required to make 3 apple pies=3 × 11/4
=33/4 pounds
Apples cost $2.49 a pound.
So, the amount spent on apples=x=33/4 × 2.49
=$20.5425
Therefore, the total amount spent on apples is $20.5425.

Step-by-step explanation:
The distance formula applies in 3 dimensions as well as 2.
d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)
d = √((-2)² +6² +3²) = √(4 +36 +9) = √49

Find the angle between u and v, rounded to the nearest tenth degree.
u = (4, 0, 2), v = (6, −3, 0)
Answer:
The angle between vectors u and v is [tex]\theta\approx36.9^\circ[/tex]
Step-by-step explanation:
Recall:
Angle between vectors u and v --> [tex]\theta=cos^{-1}(\frac{u\bullet v}{||u||*||v||})[/tex]Dot product (three-dimensional) --> [tex]u\bullet v=u_1v_1+u_2v_2+u_3v_3[/tex]Magnitude (three-dimensional, vector u) --> [tex]||u||=\sqrt{u_1^2+u_2^2+u_3^2}[/tex]Magnitude (three-dimensional, vector v) --> [tex]||v||=\sqrt{v_1^2+v_2^2+v_3^2}[/tex]Calculation:
Dot product --> [tex]u\bullet v=(4)(6)+(0)(-3)+(2)(0)=24[/tex]Magnitude (u) --> [tex]||u||=\sqrt{4^2+0^2+2^2}=\sqrt{16+0+4}=\sqrt{20}=2\sqrt{5}[/tex]Magnitude (v) --> [tex]||v||=\sqrt{6^2+(-3)^2+0^2}=\sqrt{36+9+0}=\sqrt{45}=3\sqrt{5}[/tex]Plug dot product and magnitudes into formula:
[tex]\theta=cos^{-1}(\frac{u\bullet v}{||u||*||v||})=cos^{-1}(\frac{24}{2\sqrt{5}*3\sqrt{5}})=cos^{-1}(\frac{24}{6*5})=cos^{-1}(\frac{24}{30})\approx36.9^{\circ}[/tex]
Conclusion:
The angle between vectors u and v is [tex]\theta\approx36.9^\circ[/tex]
1% of the parts produced by a factory are defective. Suppose the test for defective parts has a 99.5% accuracy and a 0.6% false positive rate. SUppose you pick a part and receive a positive test result. WHat is the probability that the part is indeed defective
Using conditional probability, it is found that there is a 0.6262 = 62.62% probability that the part is indeed defective.
Conditional Probability
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening.In this problem:
Event A: Positive test result.
Event B: Defective.
For the probability of a positive test result, we consider two scenarios.
99.5% of 1%(defective).0.6% of 100 - 1 = 99%(false positive).Hence:
[tex]P(A) = 0.995(0.01) + 0.006(0.99) = 0.01589[/tex]
The probability of a positive test result and being defective is:
[tex]P(A \cap B) = 0.995(0.01)[/tex]
The conditional probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.995(0.01)}{0.01589} = 0.6262[/tex]
0.6262 = 62.62% probability that the part is indeed defective.

Find the coordinates of point p along the directed line segment AB, from A (-2,-4) to B (6,1), so that the ratio of AP to PB is 3 to 2
Answer:
Step-by-step explanation:
x distance from A to B
6 - (-2) = 8
3/5(8) = 24/5 = 4.8 or 2/5(8) = 16/5 = 3.2
-2 + 4.8 = 2.8 6 - 3.2 = 2.8
y distance from A to B
1 - (-4) = 5
3/5(5) = 3 or 2/5(5) = 2
-4 + 3 = -1 1 - 2 = -1
P = (2.8, -1)
The coordinates of point P (rounded to one decimal place) along the directed line segment AB are approximately (2.8, -1).
Given that the line segment has been divide into ratio 3:2 by a point P, we need to find the coordinates of the point P.
To find the coordinates of point P along the directed line segment AB, such that the ratio of AP to PB is 3 to 2, we can use the concept of section formula in coordinate geometry.
Let's assume the coordinates of point P are (x, y). According to the given information, the ratio of AP to PB is 3 to 2. This means that the distance between A and P (AP) is three times the distance between P and B (PB).
The section formula states that if a point P(x, y) divides the line segment joining points A(x₁, y₁) and B(x₂, y₂) in the ratio m:n, then the coordinates of point P can be calculated as:
x = (mx₂ + nx₁) / (m + n)
y = (my₂ + ny₁) / (m + n)
In this case, m = 3 and n = 2.
Coordinates of A: (x₁, y₁) = (-2, -4)
Coordinates of B: (x₂, y₂) = (6, 1)
Ratio m:n = 3:2
Now, let's plug the values into the section formula to find the coordinates of P:
x = (3 · 6 + 2 · (-2)) / (3 + 2)
= (18 - 4) / 5
= 14 / 5
= 2.8
y = (3 · 1 + 2 · (-4)) / (3 + 2)
= (3 - 8) / 5
= -5 / 5
= -1
So, the coordinates of point P is (2.8, -1).
