Find The Slope Of The Line Of Best Fit Shown In The Figure

Answers

Answer 1

Answer:

Slope of the line of best fit = -0.34868

Step-by-step explanation:

From the figure attached,

Coordinates of the points lying on the given line are (2, 3), (2, 5), (2, 6), (3, 5), (4, 3), (5, 4) and (7, 3)

By using the linear regression calculator,

Equation of the line of best fit → y = -0.34868x + 5.38816

Comparing this equation with, y = mx + b

Slope of the line of best fit → m = -0.34868

If Rihanna deposite 1500 rupees in the school fund at 9 p.C.P.A for 2 years, what is the total amount she will get?

Answers

Answer: 1770 rupees

Step-by-step explanation:

To solve this, we first calculate the simple interest which will be:

= (P × R × T) / 100

= (1500 × 9% × 2) / 100

= (1500 × 0.09 × 2) / 100

= 270

The total amount tha she'll get will be:

= 1500 + 270

= 1770 rupees

Step-by-step explanation:

Remainder theorem says that when p(x) is divided by (x – a) the remainder is given

by p(a)

Let p(x) = ax³ + bx²+ c

P(x) when divided by (x – 3)

Using Remainder theorem, we have

A loan requires that the 4% interest be compounded monthly for five years find the number of compounding periods

Answers

Answer:

60 compounding periods

Step-by-step explanation:

The proper formula for compound interest is A = P(1 + r/n)^(nt), where r is the interest rate as a decimal fraction, n is the number of times that interest is compounded in 1 year, and t is the number of years.

In this problem, we don't need to calculate the Amount, but only the number of compounding periods.  That is nt, which here is 12*5, or 60.

Answer:

x = 44

Step-by-step explanation:

You can rewrite logarithm equations like so:

[tex]log_{b}(x) = y\\\\x = b^y[/tex]

A way to remember this is the base in the logarithm is also the base in the exponent - then remember this base b is to the power of what's on the other side - and all this is equal to whatever's in the parentheses.

In this case,

[tex]log_3(2x-7) = 4\\2x - 7 = 3^4\\x = (3^4 + 7)/2 = 44[/tex]

the answer is 63.62 for 1 circle then multiply by 24 which gets 1526.88

Step-by-step explanation:

A circle with a radius of r units is dilated by a scale factor of 7 to create a new circle. Which statement about the area of the new circle is true?

A. The area of the new circle is 7 times the area of the original circle.

B. The area of the new circle is 14 times the area of the original circle.

C. The area of the new circle is 49 times the area of the original circle.

D. The area of the new circle is squared root 7 times the area of the original circle.

Answers

Answer:

A

Step-by-step explanation:

The scale factor can be defined as the ratio of new dimension of an object after scaling to the original  dimension. The are of the new circle is 49 times the area of the original circle. The correct answer is option C.

What is Scaling factor ?

Scaling factor is a conversion factor used to change the size of a figure without changing its shape. When the size of a figure is increased, it called scaled up and when it decreases it is called as scaled down.

Given that, Scale factor of circle = 7.

Since, the scale factor of a circle is the ratio of new radius to original radius.

The new radius of circle can be written as,

r' = 7r

Thus, the area of new circle is π × (r')^2= π × (49r^2).

Hence, the area of new circle is 49 times the original circle.

A ceiling fan manufacturer claims that 89% of homes in the South have ceiling fans. A random sample of 100 Southern homes was surveyed, and 85 had ceiling fans. Let p hat = the proportion of the sample homes that have ceiling fans.

The probability that 85% or fewer homes in the South have ceiling fans is 0.098. Does this result provide convincing evidence against the manufacturer’s claim?

Options:

Yes, it is expected that at least 85 homes have ceiling fans.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.
No, the difference between the sample result and what is expected is not extreme enough.

If you start with 7,152 grams of a radioactive kind of lanthanum and the half-life is 93 minutes, how much will be left after 186 minutes

Answers

Answer:

1788 grams

Step-by-step explanation:

If you start with 7,152 grams of a radioactive kind of lanthanum and the half-life is 93 minutes, how much will be left after 186 minutes

We are to find Nt

The formula is given as:

Nt = No(1/2)^t/t½

Where

No = Initial amount = 7,152 grams

t = time elapsed = 186 minutes

t½ = Half life = 93 minutes

Nt = Amount of substance left

Nt = 7152(1/2)^186/93

= 1788 grams

A grocery store sells a bag of 6 oranges for $3.84. What is the cost of oranges, in
dollars per orange?

Answers

Answer:

Each orange would cost $0.64.

Step-by-step explanation:

If you do 3.84 and divide that by 6, you would get the answer of $0.64 for each orange.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

The cost of one orange is $0.64

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

6 oranges = $3.84

Divide both sides by 6.

1 orange = $3.84/6

1 orange = $0.64

Thus,

The cost of one orange is $0.64.

The expression represents the distance in feet an object falls after seconds. The object is dropped from a height of 906 feet.


What is the height in feet of the object 2 seconds after it is dropped?


Write an expression representing the height of the object in feet seconds after it is dropped.

Answers

Answer:

[tex]842\ \text{ft}[/tex]

[tex]y(t)=906-16t^2[/tex]

Step-by-step explanation:

Let [tex]y[/tex] be the height the object from the ground.

[tex]s[/tex] be the initial height of the object = 906 ft

[tex]u[/tex] = Initial velocity = 0

[tex]g[/tex] = Acceleration due to gravity = [tex]32\ \text{ft/s}^2[/tex]

[tex]t[/tex] = Time

The expression would be

[tex]y(t)=s-ut-\dfrac{1}{2}gt^2\\\Rightarrow y(t)=906-16t^2[/tex]

The required expression is [tex]y(t)=906-16t^2[/tex]

At [tex]t=2\ \text{s}[/tex]

[tex]y(2)=906-16\times 2^2\\\Rightarrow y(2)=842\ \text{ft}[/tex]

The height of the object after 2 seconds of falling is [tex]842\ \text{ft}[/tex].
