Answer:

2 1/2 + b = 4 2/3

The given sequence appears to be an arithmetic sequence, as the common difference between consecutive terms is 4.

The nth term of an arithmetic sequence is given by the formula: a_n = a_1 + (n-1)d, where a_1 is the first term, d is the common difference and n is the nth term.

Given that the first term of the sequence is 2, the common difference is 4.

To find the 41st term of the sequence, we can use the formula:

a_41 = 2 + (41-1) * 4 = 2 + 40 * 4 = 2 + 160 = 162

Therefore, the 41st term of the sequence is 162.

Slope is y is -1x + 1.

To enter data and find the equation's solution, we can utilize the equation's point-slope form.

use the point ( 2, 3) and the slope of 1.

m \s= \s− \s1

x \s1 \s= \s− \s2

y \s1 \s= \s3

In the point-slope formula,

y \s− \sy \s1 \s= \sm \s( \sx \s− \sx \s1 \s)

the values into the plug

y \s− \s3 \s= \s− \s1 \s( \sx \s− \s( \s− \s2 \s) \s)

symbol reduction

Distribute the 1 according to y 3 = 1 (x + 2).

Use additive inverse to find the y in the equation y = 3 = 1 x 2

y \s− \s3 \s+ \s3 \s= \s− \s1 \sx \s− \s2 \s+ \s3

The probability of rolling two ones in a row is equal to P = 1/36

We want to find the probability of rolling two ones in a row.

Remember that a dice has 6 sides, so the probability of randomly rolling a 1 is just:

p = 1/6

And if we want to do that two times then we need to have that probability twice:

q = 1/6

And the joint probability (probability of rolling two ones) is equal to the product between the individual ones:

P = p*q = (1/6)*(1/6)

P = 1/36

That is the probability.

The correct answer is C), because it is possible to create an economic model describing the relationship between fertilizer usage and yield.

The economic model would take into account the nonlinear relationship, which is shown in the graph. Specifically, the slope of the curve between one and two tons of fertilizer is approximately 2 (change in yield divided by change in fertilizer usage). This means that for every ton of fertilizer used, the yield increases by two (change in yield / change in fertilizer usage = 2). Although using more than three tons of fertilizer has minimal effect on yield, the economic model would still take this into account and provide a more accurate representation of the relationship between the two variables.

Tom's monthly mortgage repayment will be an amount of $1,144.41.

To calculate Tom's monthly mortgage repayment, we can use the formula:

[tex]M = P [ i(1 + i)^n ] / [ (1 + i)^n -1 ][/tex]

Where:

M = monthly repayment

P = the principal amount (loan amount) = $300,000 - $30,000 = $270,000

i = monthly interest rate = 2%/12 = 0.02/12 = 0.0017

n = number of months = 25 years x 12 months/year = 300 months

Plugging in the values:

M = $270,000 [ 0.0017(1 + 0.0017)³⁰⁰ ] / [ (1 + 0.0017)³⁰⁰ – 1 ]

M = $1,144.41

The number of handshakes altogether exists 45.

In mathematics, there are two alternative methods for dividing up a collection of components into subsets: combination and permutation. The subset's components can be arranged in any sequence when used together. The components of the subset are arranged in a particular order in a permutation.

A combination in mathematics is a choice of elements from a set with distinct members, where the order of the choices is irrelevant.

Combinations are a mathematical method for calculating the number of alternative arrangements in a collection of objects where the order of the selection is irrelevant. You are free to choose any combination of the things.

Answer:

The coupon that gives $14 rebate off $75 gives a lower price

Step-by-step explanation:

Let's figure out what percentage of $75 the $14 rebate coupon is

If this percentage is greater than 15% then the $14 rebate coupon gives a better discount; if not the 15% discount offers a better buy

To find what % $14 is of the $75 cost of printer, divide 14 by 75 and multiply by 100 to convert to %:

[tex]\dfrac{14}{75} \times 100 = 18.67\%\\\\[/tex]

The linear equation in two variables is -5X + 10 = Y

A linear equation in mathematics is an equation that may be written as follows: Y = aX + b where a and b are the coefficients, which are frequently real numbers, and X and Y are the variables (or unknowns). As long as they don't contain any of the variables, the coefficients can be thought of as equation parameters and can be arbitrary expressions. The coefficients must not all be 0 in order to produce a meaningful linear equation.

A linear polynomial over a field, from which the coefficients are taken, can also be equalised to zero to produce a linear equation.

Such an equation's solutions are the values that, when used as placeholders for the unknowns, result in the equality being true.

Let us assume that given equation as  linear equation in two variables

Y = aX + b

Also, from the given table, the value which satisfy the equations are

X =3, Y = -5 and X = 4, Y = -10

using these values we have

-5 = 3a +b and -10 = 4a +b

subtracting both the equations we get,

-5 = a

Now putting this value in an equation we get

b = 10

so the general equation is -5X + 10 = Y

Angle A = 83.59° (2 d.p.)

Angle C = 56.41° (2 d.p.)

Side a = 193.25 (2 d.p.)

Step-by-step explanation:

Given:

Substitute the given values into the Sine Rule formula:

[tex]\implies \dfrac{\sin A}{a}=\dfrac{\sin 40^{\circ}}{125}=\dfrac{\sin C}{162}[/tex]

Solve for angle C:

[tex]\implies \dfrac{\sin 40^{\circ}}{125}=\dfrac{\sin C}{162}[/tex]

[tex]\implies \sin C=\dfrac{162\sin 40^{\circ}}{125}[/tex]

[tex]\implies C=\sin^{-1}\left(\dfrac{162\sin 40^{\circ}}{125}\right)[/tex]

[tex]\implies C=56.4136175...^{\circ}[/tex]

Interior angles of a triangle sum to 180°. Therefore:

[tex]\implies A+B+C = 180^{\circ}[/tex]

[tex]\implies A = 180^{\circ}-B-C[/tex]

[tex]\implies A = 180^{\circ}-40^{\circ}-56.4136175...^{\circ}[/tex]

[tex]\implies A = 83.5863824...^{\circ}[/tex]

Finally, to find a, substitute the found angles and sides into the Sine Rule and solve for a:

[tex]\implies \dfrac{\sin A}{a}=\dfrac{\sin B}{b}[/tex]

[tex]\implies \dfrac{\sin 83.5863824...^{\circ}}{a}=\dfrac{\sin 40^{\circ}}{125}[/tex]
