The number of large boxes of porridge that William bought, using a system of equations, was of:

8.

A system of equations is a set of equations involving multiple variables that are related, and then operations are made to solve these equations and identify the numeric value of each variable in the context of the problem.

For this problem, the variables are defined as follows:

William buys 5 small boxes of oat porridge, hence:

x = 5.

The total weight of his purchase is of 6825 grams, hence, considering the weight of each box, the following equation is built:

325x + 650y = 6825.

It is already stated on the problem that x = 5, hence the value of y can be obtained as follows:

325(5) + 650y = 6825.

y = (6825 - 325(5))/650

y = 8 large boxes.

the sum of two odd integers will always be resulted in an odd digit.

Odd numbers are entire numbers that can't be isolated precisely into matches. Odd numbers, when separated by 2, leave a rest of 1. , 3, 5, , 9, 11, , 15  are consecutive odd numbers.

These are added together to get n + n+1, or 2n+1. Since +1 make it odd, 2n is even. Any two successive integer sums are hence odd. According to the solution is "2n + (2n + 1) = 4n +1."

Even numbers result from the addition of two fractions, but still only digits result from the addition of one odd number with one even number. In order to only receive an odd number, add one odd as well as one even.

Answer:

see explanation

Step-by-step explanation:

using the cofunction identities

cos x = sin(90 - x)

sin x = cos(90 - x)

then

cos76° = sin(90 - 76)° = sin14°

sin66° = cos(90 - 66)° = cos24°

sin53° = cos(90 - 53)° = cos37°

cos49° = sin(90 - 49)° = sin41°

The  Matched values are

cos(76) —> sin (14)

sin(66)—> cos (24)

sin(53)—> cos (37)

cos(49)—> sin (41)

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

For complementary angle,

a+ b= 90

So, sin (14)

= cos (90 - 76)

= cos 76

and, cos (37)

=sin (90 - 53)

= sin (53)

and, sin (49)

= cos (90- 41)

= cos 41

and, cos (66)

= sin (90 - 24)

= sin 24

Then, the Matched values are

cos(76) —> sin (14)

sin(66)—> cos (24)

sin(53)—> cos (37)

cos(49)—> sin (41)

Steven battling average for the whole season he played was 0.45

An equation is an expression showing the relationship between two or more numbers and variables.

Steven hit the ball 12 times out of 26 at bats in the first half of the season and 6 times out of 14 at bats in the second half of the season.

Hence:

Batting average = (total number of time he hit the ball in both season half) / (total number of balls thrown)

Therefore:

Battling average = (12 + 6)/ (26 + 14) = 18 / 40 = 0.45

The synthetic division (x²+9) by (x-3) has a quotient of x+3 and the remainder of 18

Synthetic division is a way of performing the division of polynomials, with less writing and fewer calculations than the long division method

Given: (x²+9) ÷ (x-3)

The numerator can be written as p(x)= x²+9

The zero of the denominator g(x) is 3         (Note: the sign changed)

The coefficients of p(x) are arranged as follows, with the zero of g(x) on the left:    

           3 |   1   0    9    

              |________

The first coefficient after the bar is "dropped" to the last row.

           3 |   1    0    9      

              |___________

              | 1  

The dropped number is multiplied by the number before the bar, and placed in the next column

          3  |   1     0    9  

              |          3  

              |___________

              | 1  

An addition is performed in the next column

           3 |   1     0    9  

              |          3  

              |___________

              | 1        3

The previous two steps are repeated and the following is obtained:

           3 |   1    0    9  

              |         3    9

              |___________

              | 1      3    18

Here, the last term (18) is the remainder while the rest are the coefficients of the quotient

The terms are written with increasing degree from right to left beginning with degree zero for the remainder and the result

1x + 3 | 18

Where the quotient q(x) = x+3 and the remainder r(x) = 18

Therefore, the quotient is  x+3 and the remainder is 18

The fraction of a mile that Evan has to hike and the fraction he has hiked, gives the completed statement as follows;

[tex]\frac{5}{6}[/tex] is closest to 1 and [tex]\frac{2}{5}[/tex] is closest to [tex]\frac{1}{2}[/tex]. So the difference is closest to [tex]\frac{1}{2}[/tex]

A fraction is a representation of the part of a whole of an item or collection of items. The distance Evan's hiking trail of [tex]\frac{5}{6}[/tex] miles is a fraction of a mile.

The length of the trail = [tex]\frac{5}{6}[/tex] mile

The distance Evan has hiked = [tex]\frac{2}{5}[/tex] mile

The distance Evan has left to hike is given by the difference between the length of the trail and the distance Evan has hiked as follows;

Distance remaining = [tex]\frac{5}{6} -\frac{2}{5} = \frac{13}{30}[/tex]

Representing the numbers in decimal form, we have;

[tex]\dfrac{5}{6} = 0.8\overline 3[/tex]

The value of [tex]\frac{5}{6}[/tex] is close to 1

[tex]\dfrac{2}{5} = 0.4[/tex]

The value of [tex]\frac{2}{5}[/tex] is closest to 0.5

[tex]\dfrac{13}{30} = 0.4\overline 3[/tex]

The difference between [tex]\frac{5}{6}[/tex] and [tex]\frac{2}{5}[/tex], which is [tex]\frac{13}{30}[/tex] is therefore closest to [tex]\frac{1}{2}[/tex]

The completed statement is therefore;

[tex]\frac{5}{6}[/tex] is closest to 1 and [tex]\frac{2}{5}[/tex] is closest to [tex]\frac{1}{2}[/tex] so the difference is closest to [tex]\frac{1}{2}[/tex]

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

The given scenario can be modelled as a right triangle (see attachment).

Therefore, the bearing is 90° + θ (shown in green on the attached diagram).

To find angle θ, use the cosine trigonometric ratio:

[tex]\implies \cos{\theta}=\dfrac{A}{H}[/tex]

[tex]\implies \cos{\theta}=\dfrac{624}{927}[/tex]

[tex]\implies \theta=\cos^{-1}\left(\dfrac{624}{927}\right)[/tex]

[tex]\implies \theta=47.69018863...[/tex]

[tex]\implies \theta=48^{\circ}\; \; \sf (nearest\;degree)[/tex]

Therefore, the bearing of the drawbridge from the tower is:

[tex]\begin{aligned}\implies \sf Bearing&=90^{\circ}+\theta\\&=90^{\circ}+48^{\circ}\\&=138^{\circ} \end{aligned}[/tex]

Answer:

Let s, c, y and t represent the ages of Sofia, Carlos, Lily and Tony respectively.

c + y = 2s ------ equation (1)

t + 4 = c ------ equation (2)

6t + 1 = y ------ equation (3)

Since Sofia is 38 years old, substitute s = 38 into equation (1):

c + y = 2(38)

        = 76 ------ equation (4)

Substitute equations (2) and (3) into equation (4):

t + 4 + 6t + 1 = 76

          7t + 5 = 76

                7t = 71

∴ t = 10 (to the nearest whole number)

∴Tony is 10 years old (to the nearest whole number).

a.  I would rather compound annually at 5 % interest

b.  I would increase the simple interest rate if i were to change my answer

Since you have $200 to invest for 10 years, would you rather invest your money in a bank that pays 7% simple interest or 5% interest compounded annually, we need to determine the amount of each type of interest after 10 years.

Since  you have $200 to invest for 10 years at  7% simple interest, using the simple interest formula for the amount, we have

A = P(1 + rt) where

Substituting the values of the variables into the equation, we have

A = P(1 + rt)

A = 200(1 + 0.07 × 10)

A = 200(1 + 0.7)

A = 200(1.7)

A = 340

Also, since  you have $200 to invest for 10 years at  5% interest compounded annually, using the compound interest formula for the amount, we have

A' = P(1 + r)ⁿ where

Substituting the values of the variables into the equation, we have

A' = P(1 + r)ⁿ

A' = 200(1 + 0.07)¹⁰

A' = 200(1.07)¹⁰

A' = 200(1.9672)

A' = 393.43

Since A' = $393.43 > A = $340, i would rather compound annually at 5 % interest

To change my answer, I would increase the simple interest rate if i were to change my answer

Systematic random sampling

Systematic sampling is a form of probability sampling technique in which sample members are chosen from a wider population using a defined, periodic interval but a random beginning point. By dividing the population size by the desired sample size, this interval, also known as the sampling interval, is computed.

If the periodic interval is predetermined and the starting point is random, systematic sampling is still regarded as random even though the sample population has been chosen in advance.
