Answer:
The approximate error of weight is 6.241 - 6 = 0.241 lbs
The approximate error of the given weight is 0.241 lbs
How to find the approximate error of weight?The approximate error of weight is the difference between the claimed weight and the actual weight, which is:
Approximate error = Actual weight - Claimed weight
As per the question, we have
Actual weight = 6.241 lbs
Claimed weight = 6 lbs
Substitute the values in the formula and we get:
Approximate error = 6.241 lbs - 6 lbs
Approximate error = 0.241 lbs
Therefore, the approximate error of weight is 0.241 lbs.
This means that the claimed weight is off by 0.241 lbs, which could be significant depending on the context.

68 times the difference between a number and 45 is equal to the number plus −98
Answer:
The number can be expressed in multiple forms
Fraction form \(x=\frac{2962}{67}\) or decimal form \(x=44.21\)
Step-by-step explanation:
Lets break the problem down
"times" is multiplication *
The difference between 2 numbers is subtraction \((x-y)\)
A number plus a number is addition \(x+y\)
\(68(x-45)=x+-98\)
Lets solve for \(x\).
Lets start on the left side.
Distribute 68 to the terms inside the parenthesis.
\(68x-3060=x+-98\)
A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign.
\(68x-3060=x-98\)
Subtract \(x\) from both sides of the equation.
\(68x-3060-x=-98\)
Subtract \(x\) from \(68x\).
\(67x-3060=-98\)
Add 3060 to both sides of the equation.
\(67x=2962\)
Divide both sides of the equation by 67.
\(x=\frac{2962}{67}\) or as a decimal \(x=44.21\)

how many miles could he ride in 3 hr
In case whereby Jake rides his bicycle 6 miles in 3/5 of an hour. At this rate, the number of miles could he ride in 3 hours is 30 miles
How can the number of miles be calculated?The distance = bicycle 6 miles
number of hours =3/5 of an hour
then the rate = 6/ (3/5)
Then we can calculate the number of miles with the 6milesi n 3/5 hours as;
= (6 * 5/3 )
=30/3
=10
Then the rate will be 10 miles in 1 hour , hence the number of miles he will ride in 3hrs
=10 * 3 hours

The map shows an obstacle course at a school fair. The units are given in yards.
What is the total distance of
the obstacle course?
? yards
Start
(-40, -10)
Tire
Race
(-40, -30)
Finish
(10, 20)
Monkey
Bars
(40,20)
Rope
Climb
(40,-30)
The total distance of the obstacle course can be calculated by finding the distance between each pair of consecutive points and adding them up. The distance between two points (x1, y1) and (x2, y2) can be calculated using the formula: distance = sqrt((x2 - x1)^2 + (y2 - y1)^2).
Using this formula, we can calculate the distances between each pair of consecutive points as follows:
Start to Tire Race: distance = sqrt((-40 - (-40))^2 + (-30 - (-10))^2) = 20 yards
Tire Race to Rope Climb: distance = sqrt((40 - (-40))^2 + (-30 - (-30))^2) = 80 yards
Rope Climb to Monkey Bars: distance = sqrt((40 - 40)^2 + (20 - (-30))^2) = 50 yards
Monkey Bars to Finish: distance = sqrt((10 - 40)^2 + (20 - 20)^2) = 30 yards
Adding up all these distances, we get a total distance of 20 + 80 + 50 + 30 = 180 yards for the obstacle course.

Find the exact value of each of the remaining trigonometric functions of θ. Rationalize denominators when applicable.
secθ=−8, given that sinθ>0
The exact values of the remaining trigonometric functions of θ are:
sin(θ) = √(1/64)
cos(θ) = -8
tan(θ) = -8√(1/64)
csc(θ) = 1
cot(θ) = -√(1/64) / 8
Given that sec(θ) = -8 and sin(θ) > 0, we can find the exact values of the remaining trigonometric functions using the Pythagorean identity:
sec^2(θ) = 1/sin^2(θ)
Substituting the value of sec(θ), we have:
(-8)^2 = 1/sin^2(θ)
64 = 1/sin^2(θ)
sin^2(θ) = 1/64
sin(θ) = ±√(1/64)
Since sin(θ) > 0, we take the positive square root:
sin(θ) = √(1/64)
Next, we use the reciprocal identity for cosecant:
csc(θ) = 1/sin(θ)
Substituting the value of sin(θ), we have:
csc(θ) = 1/√(1/64) = 8√(1/64) = 8/√(64) = 8/8 = 1
Next, we use the reciprocal identity for cotangent:
cot(θ) = 1/tan(θ)
We can find the value of tan(θ) using the definition:
tan(θ) = sin(θ) / cos(θ)
Substituting the values of sin(θ) and cos(θ), we have:
tan(θ) = √(1/64) / (-8) = -√(1/64) / 8
Finally, we use the reciprocal identity for a tangent:
tan(θ) = 1/cot(θ)
Substituting the value of cot(θ), we have:
tan(θ) = -8√(1/64)
Therefore, the exact values of the remaining trigonometric functions of θ are:
sin(θ) = √(1/64)
cos(θ) = -8
tan(θ) = -8√(1/64)
csc(θ) = 1
cot(θ) = -√(1/64) / 8

Which value of m makes this equation true? m - 8 = -1
m = 9
m=7
m= -9
m = -7
Answer:
The answer is 7 because if we write 7 - 8 = -1, then we could see that the answer would be -1 since 7 is 1 value lower than 8, and 8 - 8 = 0, so if 7 is lower than 8 by 1, then you would go one value lower from 0, which is -1. You can also figure this out by looking at a number line and starting from 7 and then going backwards 8 times and whatever number you land on after going back 8 times is your answer.

Solve by completing the square:
x2 + 3x – 9 = 0
Answer:
\(x=\dfrac{-3\pm3\sqrt{5}}{2}\)
Step-by-step explanation:
Given equation:
\(x^2+3x-9=0\)
Completing the square
Move the constant to the right side by adding 9 to both sides:
\(\implies x^2+3x=9\)
Add the square of half the coefficient of x to both sides:
\(\implies x^2+3x+\left(\dfrac{3}{2}\right)^2=9+\left(\dfrac{3}{2}\right)^2\)
\(\implies x^2+3x+\dfrac{9}{4}=\dfrac{45}{4}\)
Factor the trinomial on the left side:
\(\implies \left(x+\dfrac{3}{2}\right)^2=\dfrac{45}{4}\)
Square root both sides:
\(\implies x+\dfrac{3}{2}=\pm\sqrt{\dfrac{45}{4}}\)
\(\implies x+\dfrac{3}{2}=\pm\dfrac{\sqrt{45}}{\sqrt{4}}}\)
\(\implies x+\dfrac{3}{2}=\pm\dfrac{\sqrt{9 \cdot 5}}{2}\)
\(\implies x+\dfrac{3}{2}=\pm\dfrac{\sqrt{9} \sqrt{5}}{2}\)
\(\implies x+\dfrac{3}{2}=\pm\dfrac{3\sqrt{5}}{2}\)
Subtract 3/2 from both sides:
\(\implies x=\pm\dfrac{3\sqrt{5}}{2}-\dfrac{3}{2}\)
\(\implies x=\dfrac{-3\pm3\sqrt{5}}{2}\)

Range:
Variance:
Std Deviation:
The required statistical parameters has been computed as follows:
Range = 15.
Standard deviation, SD = 4.4441.
Variance = 19.75.
How to calculate the range?Mathematically, the range of a data set can be calculated by using this formula;
Range = Highest number - Lowest number
Range = 36 - 21
Range = 15.
How to calculate the mean?Mathematically, the mean for these data sets would be calculated by using this formula:
Mean = [F(x)]/n
F(x) = 22 + 29 + 21 + 24 + 27 + 28 + 25 + 36
F(x) = 212.
Mean = 212/8
Mean = 26.5
Next, we would calculate the standard deviation by using this formula:
SD = √(1/n × ∑(xi - u₁)²)
SD = √(1/5 × ∑(22 - 26.5)² + 1/5 × ∑(29 - 26.5)² + 1/5 × ∑(21 - 26.5)² + 1/5 × ∑(24 - 26.5)² + 1/5 × ∑(27 - 26.5)² + 1/5 × ∑(28 - 26.5)² + 1/5 × ∑(25 - 26.5)² + + 1/5 × ∑(36 - 26.5)²)
Standard deviation, SD = 4.4441.

express 2 cos 35 sin 67 as a sum
2 cos 35 sin 67 can be expressed as the sum of sin(102) and -sin(32).
To express 2 cos 35 sin 67 as a sum, we can use the trigonometric identity for the product of two sine or cosine functions.
Specifically, the identity states that 2 cos A sin B can be written as
sin(A + B) + sin(A - B).
Applying this identity, we have:
2 cos 35 sin 67 = sin(35 + 67) + sin(35 - 67)
Simplifying the expressions inside the sine functions:
sin(102) + sin(-32)
Since the sine function is an odd function,
sin(-x) = -sin(x),
so we can rewrite the equation as:
sin(102) - sin(32)
Therefore, 2 cos 35 sin 67 can be expressed as the sum of sin(102) and -sin(32).

Peter had 208 Canadian stamps and 186 Mexican stamps for sale. The stamps were mixed up and sold in packets of 6. How many packets of stamps were there? How many stamps were left over?
Answer:
65 packets and 4 stamps
Step-by-step explanation:
The first thing we see is that the stamps are mixed... which means they must be added.
208 + 186 = 394 stamps total
Now we see that each packet has 6 stamps. So we divide the number of stamps in total by 6.
394/6= 65.66667
Now we see from that number that the stamps can't quite make 66 packets, so there are 65 packets.
Now we find the number of stamps left over by multiplying the number of packets by 6.
65 x 6= 390
Now we take the total number of stamps minus the number of stamps in packets.
394 - 390 = 4
Therefore, there are four stamps left over.

The length of a rectangle is six times its width. If the perimeter of the rectangle is 126 in, find its length and width.
Answer:
Length = 54 inches and width = 9 inches.
Step-by-step explanation:
Let the width be x in , then the length is 6x in.
So 2*x + 2*6x 126
14x = 126
x = 9 in.
So L = 6*9 = 54 in, and W = 9 in.
Step-by-step explanation:
Perimeter = 2l + 2w
but;
Perimeter = 126
lenght = 6w ( let the width be the variable w)
126 = 2(6w) + 2(w)
126 = 12w + 2w
126 = 14w
126/14 =w
w = 9
Therefore width is 9
and length = 6× 9 = 54
