5) Abhasra invests $7,053 in a savings
account with a fixed annual interest rate of
3% compounded quarterly. What
will the account balance be after 4 years?
Answer:
After 4 years the account balance will be $ 7,948.67.
Step-by-step explanation:
Given that Abhasra invests $ 7,053 in a savings account with a fixed annual interest rate of 3% compounded quarterly, to determine what the account balance will be after 4 years, the following calculation must be performed:
7.053 x (1 + 0.03 / 4) ^ 4x4 = X
7,053 x 1.0075 ^ 16 = X
7.053 x 1.12699211 = X
7,948.67 = X
Therefore, after 4 years the account balance will be $ 7,948.67.

A company makes wax candles in the shape of a cylinder. Each candle has a radius of 3 inches and a height of 2 inches. How much wax will the company need to make 270 candles?
Use 3.14 for pie and do not round your answer.
Answer:
[tex] 15,260.4 \: {in}^{3} [/tex]
Step-by-step explanation:
Radius of candle = 3 inches
Height of candle = 2 inches
Wax needed to make one candle = Volume of one cylindrical candle
[tex] =\pi r^2 h[/tex]
[tex] =3.14(3)^2 (2)[/tex]
[tex] =56.52\: in^3 [/tex]
Volume of wax needed to make 270 candles
[tex] = 270 \times wax\: needed \: to\:make \: one \: candle \\ \\ = 270 \times 56.52 \\ \\ = 15,260.4 \: {in}^{3} [/tex]
find the value of X round to the nearest 10th
Answer:
x ≈ 80.4
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan15° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{300}[/tex] ( multiply both sides by 300 )
300 × tan15° = x , then
x ≈ 80.4 ( to the nearest tenth )

One method for straightening wire before coiling it to make a spring is called "roller straightening." The article "The Effect of Roller and Spinner Wire Straightening on Coiling Performance and Wire Properties" (Springs, 1987: 27–28) reports on the tensile properties of wire. Suppose a sample of 16 wires is selected and each is tested to determine tensile strength (N/mm2 ). The resulting sample mean and standard deviation are 2160 and 30, respectively. a. The mean tensile strength for springs made using spinner straightening is 2150 N/mm2 . What hypotheses should be tested to determine whether the mean tensile strength for the roller method exceeds 2150? b. Assuming that the tensile strength distribution is approximately normal, what test statistic would you use to test the hypotheses in part (a)? c. What is the value of the test statistic for this data? d. What is the P-value for the value of the test statistic computed in part (c)? e. For a level .05 test, what conclusion would you reach?
Answer:
We accept H₀, we don´t have enough evidence to claim that the procedure improves the tensile strength above the peviuos average
Step-by-step explanation:
Information:
μ = 2150
Sample size n = 16
Sample mean x = 2160
Sample standard deviation s = 30
a) Test Hypothesis
Null Hypothesis H₀ x = μ
Alternative Hypothesis Hₐ x > μ
b) If Tensile strength is approximately normal distribution we should use t-student statistic for testing the above hypothesis.
t(s) = ?? with df = n - 1 df = 15
c) t(s) = ( x - μ ) / s/√n
t(s) = ( 2160 - 2150 ) / 30/√16
t(s) = 10*4 / 30
t(s) = 1,33
d) In t-student we look for p-vale for 1,33 and df = 15
p-value = 0,1
e) If the level of significance is 0,05, then α/2 = 0,025
we compare p-value and level of significance
p-value 0,1 > 0,025
Then p-value is bigger than the significance level, we should accept H₀

Christopher is taking a multiple choice test with a total of 100 points available. Each question is worth exactly 2 points. What would be Christopher's test score (out of 100) if he got 10 questions wrong? What would be his score if he got xx questions wrong?
Answer:
If im not wrong, if every question is 2 points of 100 points in total means that are 50 questions, so if he gets 10 wrong then he would be losing 20 points which his final grade would be 80!
Answer:
Score with 10 questions wrong: 80
Score with x questions wrong: 100−2x
Step-by-step explanation:
each point is deducted by 2 pts and so, with 10 question, he got an 80.
100 is the availability of the points and 2x means which the points were lost

Step-by-step explanation:
To find CB, apply trigonometric function.
Reference angle = 60°
Hypotenuse = 18
Adjacent = CB
Apply CAH:
Cos 60 = Adj/Hyp
Cos 60 = CB/18
Cos 60 × 18 = CB
CB = Cos 60 × 18
CB = 9
