Answers

Answer 1

The correlation coefficient for the data in the given table is 0.28.

What is the correlation coefficient?

Correlation coefficients are used to measure how strong a relationship is between two variables.

Number of flowers X   Total cost(in$) Y

          8                          12

          12                        40

          6                          15

         20                        20

       ∑X=46                  ∑X=87

The image of the correlation coefficient formula has been attached.

X mean = 11.5

Y mean = 21.75

Using the attached formula

Correlation coefficient r = 0.28

Therefore, the correlation coefficient for the data in the given table is 0.28.

What is the hourly rate necessary to earn $68,120 a year ? How much is her weekly salary?

Maura is planning to buy a new car, she wants to save $4000 for the down payment. How many weeks does she need to work before she gets that amount?

Answers

Mayra weekly salary is $1310 and she would need 4 weeks salary in order to afford a $4000 down payment on that car.

Data;

Total number of weeks = 52Weekly hours = 40Yearly target = $68,120

Weekly Salary

To calculate her weekly salary, let's divide her annual target by 52 week which the number of weeks present in a year.

Her weekly salary will be

[tex]x = \frac{68120}{52} \\x = 1310[/tex]

Her weekly salary is $1310

To be able to afford a $4000 down payment, she has to work at least 4 weeks.

What is the formula for low of cosine?

The Law of Cosines, which tells us

[tex]a^{2}=b^{2} +c^{2} -2bccosA[/tex]

giving us a quadratic equation for b we can solve.  But let's do it with the Law of Sines as asked.

[tex]\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}[/tex]

We have c,a,A so the Law of Sines gives us sin C

[tex]sinC=\frac{csina}{a} =\frac{5.4sin20}{3.3} =0.5597[/tex]

There are two possible triangle angles with this sine, supplementary angles, one acute, one obtuse

[tex]C_{a}=arcsin(0.5597)=34.033^{0}[/tex]

[tex]C_{0}=180-C_{a} =145.96^0[/tex]

Both of these make a valid triangle with A=20°.   They give respective B's:

[tex]B_{a}=180-A-C_{a} =125.96^0[/tex]

[tex]B_{0}=180-C_{0} =14.033^0[/tex]

So we get two possibilities for b:

[tex]b=\frac{asinB}{sinA} \\\\b_{a} =\frac{3.3sin125.96}{sin 20} \\\\b_{a}=7.8\\\\ b_0=2.3[/tex]

Answers

Measurements are the metric units of an item, quantity or object

The length of the beetle is 0.5 inchThe length of the ladybug is 0.25 inchThe length of the butterfly is 1 inch

How to measure the insects

Beetles

The beetle covers two marks in a total length of 1 inch of 4 marks

So, the measurement of the beetle is:

[tex]Beetle = \frac{2\ inch}{4}[/tex]

Evaluate the quotient

[tex]Beetle = 0.5\ inch[/tex]

Ladybugs

The ladybug covers one mark in a total length of 1 inch of 4 marks

So, the measurement of the ladybug is:

Evaluate the quotient

[tex]Ladybug = 0.25\ inch[/tex]

Butterfly

The butterfly covers four marks in a total length of 1 inch of 4 marks

How to calculate intrest

Answers

Answer:

You can calculate Interest on your loans and investments by using the following formula for calculating simple interest: Simple Interest= P x R x T ÷ 100, where P = Principal, R = Rate of Interest and T = Time Period of the Loan/Deposit in years.

Formula: Simple Interest=P×r×t where: P=Principal amount; r=Annual interest rate; t=...

Principal Amount: Principal Amount remains constant on Simple Interest

Meaning: Simple Interest is calculated on the Principal Amount for the entire tenure

Calculation: It is easy to calculate Simple Interest

Answer:

To calculate simple interest, you can use a specific formula:

I (interest) = p (principal) x r (rate) x t (time)

Important: Rate is always a decimal, and time must be a compatible unit that matches with the rate (months, years, etc.).

Answers

A sinusoidal equation can be used to describe the height because the height depends on a periodic motion, and the equation can be written as:

h(t) = 13ft*sin(pi*t) + 24ft

Why a sinusoidal equation can be used?

Remember that the sine function has a periodicity, such that:

sin(x + 2pi) = sin(x).

So, for a circle where if you do a complete rotation you end in the initial place, so there can be a relation between the height and a sinusoidal equation.

Notice that the initial position is 24ft above the ground, so we can write this, at the moment, as:

h(x) = Asin(n*t) + 24ft

A is the amplitude, it defines the maximum height and minimum height, both depend on the radius (the maximum height is 24ft plus the radius, the minimum height is 24ft minus the radius) then we write:

h(t) = 13ft*sin(kt) + 24ft

k depends on how much time takes to do a full rotation. We know that the sine function does a "complete cycle" in 2pi, while the wheel does a full rotation in 2 seconds, then we have that:

k*2 = 2pi

k = (2pi)/2s = pi

Then the sinusoidal equation that represents the height is:

h(t) = 13ft*sin(pi*t) + 24ft
