Answers

Answer 1

Based on the four scenarios of statistical studies given, a study which uses a sample statistic is: D. As part of her senior project, Kaisa asked 84 of her classmates if they voted in the last presidential election, 39 said yes.

What is a sample statistic?

In Mathematics and Statistics, a sample statistic can be defined as a small piece of statistical information that is obtained by a researcher or scientist from the sample of a population.

This ultimately implies that, a sample statistic simply refers to any numerical quantity (figure) or data that is generated from the sample of a population by a researcher or scientist.

In this context, we can reasonably infer and logically deduce that 84 of Kaisa's classmates represent the sample of the total population while the 39 classmates who answered yes represent the sample statistic.

In conclusion, the statistical study that was conducted by Kaisa is a study that represent the sample statistic.

write an equation for a line parallel to y = − 2 x − 3 and passing through the point (3,-3)

Answers

Equation of line parallel to y = − 2 x − 3 and passing through the point (3,-3) is y = -2x + 3.

When two lines are called parallel?

Two lines are parallel lines if they do not intersect.

The slopes of the lines are the same.

f(x)= mx + b and g(x)= nx + c are parallel if m = n.

According to the given question:

Given equation of line is y = −2x − 3

If the new line is parallel, then it will have the same slope.

y = -2x + b

Now this line passes through the point (x,y) = (3,-3) so put in the x and y values into the equation above, solve for b

-3 = -2(3) + b

b = 3

Therefore the required equation of line is

y = -2x + 3

The investments arranged from the least to the greatest amount of interest are:

Investment of $1600 at 5% interest rate for 8 years.

Investment of $1600 at 7% interest rate for 8 years.

Investment of $1600 at 7% interest rate for 12 years.

What is simple interest?

Simple interest is the formula that is used to determine the interest that is earned when an amount is investment at an interest rate over a number of years.

Interest earned with simple interest increases linearly over the investment period. This means that the interest earned each year of the investment period is a constant amount.

Simple interest = amount invested x interest rate x year

Simple interest = $1600 x 0.07 x 8 = $896

Simple interest = $1600 x 0.05 x 8 = $640

Simple interest = $1600 x 0.07 x 12 = $1344

How long will it take 2000 dollars to double if it is invested at 8% interest compounded semi-annually?

Answers

The time it will take the 2000 dollar invested at 8% is t= 9.006468342 years

Compound Interest

Compound interest can be define as the addition of interest on the loan to the principal sum of the deposit.

2 = (1+8%) ^t

where t is the time of the year

2= (1 +8%)^t

2 = (1+8/100)^t

2 =   ( 1 0.8)^t

Take the log of both sides

log 2 = log 1.08^t

log 2 = t log 1.08

Divide both sides by log 1.08

log 2/ log 1.08 = t

t= 9.006468342 years

Therefore, the time it will take the dollar invested at 8% is t= 9.006468342 years

Find equation of plane pass through points (-2,1,3), (0,4,8) and (-1 ,-1,0)​

Answers

The equation of plane is x + 11y + 7z - 30 = 0

What is equation?

An equation is said to be a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for example, the two expressions 3x + 5 and 14 are separated by the symbol "equal."

Let  ( x₁, y₁, z₁ ) ( x₂, y₂, z₂ ) ( x₃, y₃, z₃ ) be the coordinates,

we know that equation of plane is:

[tex]\left[\begin{array}{ccc}x-x1&y-y1&z-z1\\x2-x1&y2-y1&z2-z1\\x3-x1&y3-y1&z3-z1\end{array}\right][/tex] = 0

( -2, 1, 3 )  ( 0, 4, 8 )  ( -1, -1, 0 )

[tex]\left[\begin{array}{ccc}x+2&y-1&z-3\\0+2&4-1&8-3\\-1+2&-1-1&0-3\end{array}\right][/tex] = 0

[tex]\left[\begin{array}{ccc}x+2&y-1&z-3\\2&3&5\\1&-2&-3\end{array}\right][/tex] = 0

On solving this determinant,

(x+2) (-9+10) - (y-1) (-6-5) - (z-3) (-4-3) = 0

(x+2) - (y-1) (-11) - (z-3) (-7) = 0

x + 2 + 11y - 11 + 7z - 21 = 0

x + 11y + 7z - 30 = 0

Therefore, this is the required equation.

a. Find the bearing from O to A.
b. Find the bearing from O to B.
c. Find the bearing from O to C.
d. Find the bearing from A to O.

Answers

Answer:

a.  335°

Step-by-step explanation:

Bearing: The angle (in degrees) measured clockwise from north.

a.  The bearing from O to A

Measure the angle from the positive y-axis, clockwise to point A.

Angles on a straight line sum to 180°, so the angle between the negative x-axis and point A is (180° - 115°).

Bearing = 270° + (180° - 115°) = 335°

b.  The bearing from O to B

Measure the angle from the positive y-axis, clockwise to point B.

Bearing = 270° - 48° = 222°

c.  The bearing from O to C

Measure the angle from the positive y-axis, clockwise to point C.

Bearing = 180° - 27° = 153°

d.  The bearing from A to O

Measure the angle clockwise from north of point A to point O.

Bearing = 180° - 25° = 155°

The expression which represents the function evaluation (f -g)(x) according to the task content is; (f -g)(x) = 2x³ +5x² -8x -4.

Which expression represents (f-g)(x) according to the functions given?

It follows from the task content that the required function evaluation required is; (f -g)(x).

Given;

f(x) = 2x³ +5x² - 6x - 7

g(x)=2x-3

To find;

(f-g)(x).

Since; (f -g)(x) = f(x) - g(x), the resulting expression for (f -g)(x) is;

(f -g)(x) = 2x³ +5x² -6x -7 -2x +3

(f -g)(x) = 2x³ +5x² -6x -2x -7 +3

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

Kiran has $191254 more amount than Isaac.

What is compound interest?

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

Kiran:

P = $1500

r = 81%

n = continuously

t = 6 years

A = P [tex]e^{rt}[/tex]

[ e = 2.71828 }

A = 1,500.00 x [tex]2.71828^{0.81\times6}[/tex]

A = $193,536.30

Isaac:

P = $1,500

r = 7%

n = 360

t = 6 years

A = 1500 [tex](1 + 0.07/360)^{360\times6}[/tex]

A = $2,282.85

Now,

The difference between Kiran's and Isaac's amount.

= $193,536.30 - $2,282.85

= $191253.45

= $191254

Thus,

Kiran has $191254 more amount than Isaac.

b) The estimate for the percentage of the bill left as a tip with a bill of $50 is a non-reasonable -4.5%.

What is the line of best fit?

The line of best fit in this problem is defined as follows:

y = -0.632x + 27.1.

In which the variables are defined as follows:

x is the total bill, in dollars.y is the percentage of the total bill left as a tip.

Hence, for a bill of $15, the estimate is found replacing x by 15, as follows:

y = -0.632(15) + 27.1 = 17.62%.

Which is reasonable, as it is a positive number.

For a bill of $50, the estimate is obtained as follows:

y = -0.632(50) + 27.1 = -4.5%.
