Is it possible to construct a triangle with its sides as 9.1 cm 8.3 cm and 17.5 cm?

The total distance travelled on the cycle is 30.46m and the acceleration  is the last 8 seconds is 0.85 m/s².

"Acceleration is the measure of the speed at which velocity changes."

OR "Acceleration depends upon the velocity if the velocity continously increases or decreases the acceleration will be produced."

Positive acceleration results from continuously increasing velocity.

Negative acceleration will be negative if the velocity is continuously decreasing.

FORMULA

Acceleration is defined as a change in velocity divided by time, or a = (Vf-Vi)/t UNIT.

Meter/second+square, or m/S², is the SI unit of velocity in the MKS system.

a. Total distance = Hypotenuse₁ + mid distance + Hypotenuse₂

Hypotenuse₁ = [tex]$ \sqrt{10^2 + 6^2} $[/tex]

Hypotenuse₁ = 11.66m

mid distance = 12 - 6

                      = 6m

Hypotenuse₂ = [tex]$ \sqrt{10^2 + (20-12)^2} $[/tex]

Hypotenuse₂ = [tex]$ \sqrt{10^2 + (8)^2} $[/tex]

Hypotenuse₂ = 12.80m

Total distance = 11.66m + 6m + 12.80m

Total distance = 30.46m

b. Acceleration  [tex]{\displaystyle ={\frac { \text{v - u} }{t}}[/tex]

[tex]\displaystyle = {\frac { \text{12.80 - 6} }{8}[/tex]

[tex]\displaystyle = {\frac { 6.80 }{8}[/tex]

0.85 m/s²

Thus, the total distance travelled on the cycle is 30.46m and the acceleration  is the last 8 seconds is 0.85 m/s².

The area of the region enclosed by the inner loop of the curve can be calculated by integrating the function r = 6 + 12 sin θ over the interval of θ.

The area of the inner loop is given by Area = 1/2 ∫r^2 dθ = 1/2 ∫(6 + 12 sin θ)^2 dθ

We can solve this integral by breaking it into two parts: Area = 1/2 (∫(6 + 12 sin θ)^2 dθ) = 1/2(∫36 + 72sin θ + 144sin^2 θ dθ)

The first integral is simple and equals to 36*θ and the second one is equal to 48θ - 48cos(2θ)

The limits of integration are [0, 2π]

So the area of the inner loop is 1/2(36*2π + 48(2π) - 48(2)) = 72π

So the area of the region enclosed by the inner loop of the curve is 72π square units.

P( X < 9.85 or X > 10.15 ) ≈ 0.3171 up to four decimal places.

P( X < 9.85 or X > 10.15 ) ≈ 0.0027 up to four decimal places.

The simple definition of probability is the likelihood that something will occur. We can discuss the probabilities of different outcomes, or how likely they are if we are unclear about how an event will turn out. Statistics refers to the study of occurrences subject to probability.

According to the question

a) Assuming that X is the random variable that takes the place of the number of defectives and has a normal distribution with a mean of 10 ounces and a standard deviation (σ) of 0.15.

The random variable's values deviate from the mean by 1, causing them to either exceed or fall short of (10 + 0.15) and (10-0.15)

= 10.15 or 9.85.

The following formula may be used to determine the likelihood that there will be either more or lesser defects than the range of 10.15 to 9.85:

P( X < 9.85 or X > 10.15 ) = 1 - P[tex](\frac{9.85-10}{0.15} < \frac{X - 10}{0.15} < \frac{10.15-10}{0.15} )[/tex]

P( X < 9.85 or X > 10.15 ) = 1 - φ(1) - φ(-1)

Now we calculate the value of z for z = 1 and z = -1; we have: 0.841345 and 0.158655 respectively

P( X < 9.85 or X > 10.15 ) = 1 - (0.841345 - 0.158655)

P( X < 9.85 or X > 10.15 ) = 0.31713

P( X < 9.85 or X > 10.15 ) ≈ 0.3171 up to four decimal places.

b) It is possible to lower the process standard deviation to 0.05 by making modifications to the process design.

The following formula may be used to determine the likelihood that the number of defectives is either larger than 10.15 or lesser than 9.85:

P( X < 9.85 or X > 10.15 ) = 1 - P[tex](\frac{9.85-10}{0.15} < \frac{X - 10}{0.15} < \frac{10.15-10}{0.15} )[/tex]

P( X < 9.85 or X > 10.15 ) = 1 - φ(3) - φ(-3)

Now we calculate the value of z for z = 3 and z = -3; we have: 0.99865 and 0.00135 respectively

P( X < 9.85 or X > 10.15 ) = 1 - (0.99865 - 0.00135)

P( X < 9.85 or X > 10.15 ) = 0.00271

P( X < 9.85 or X > 10.15 ) ≈ 0.0027 up to four decimal places.

(c) What is the benefit of increasing the number of standard deviations from the mean for process control limits by minimizing process variation?

As we can see from the reduction from a to b above, the key benefit of minimizing process variance is that it will decrease the likelihood of receiving a defective item.

Step-by-step explanation:

f(1) = 5 = 4*1 +1

f(9) = 37 = 4*9+1

f(6) = 4*6+1 = 25

f(f(6)) = f(25) = 4*25+1 =101

Answer:

  101

Step-by-step explanation:

Given the values of a linear function f(1) = 5 and f(9) = 37, you want the value of f(f(6)).

The given ordered pairs are (1, 5) and (9, 37). Using these, we can find the slope of the function to be ...

  m = (y2 -y1)/(x2 -x1)

  m = (37 -5)/(9 -1) = 32/8 = 4

The y-intercept is ...

  b = y -mx

  b = 5 -4(1) = 1

So the function in slope-intercept form is ...

  y = mx +b

  f(x) = 4x +1

The value of f(6) is ...

  f(6) = 4·6 +1 = 25

The value of f(f(6)) is ...

  f(f(6)) = f(25) = 4·25 +1 = 101

The value of f(f(6)) is 101.

The equation of the line that passes through the points (-6,4) and (-2,2) is y - 4 = -1/2(x + 6)

What is the equation of the line?

To find the equation of a line that passes through two given points, we can use the point-slope form of the equation of a line, which is:

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line, and m is the slope of the line.

The slope of the line can be found by using the two points:

m = (y2 - y1) / (x2 - x1)

So,

m = (2 - 4) / (-2 - (-6)) = -2/4 = -1/2

We know that the line passes through the point (-6,4) so we can substitute the values into the equation:

y - 4 = -1/2(x + 6)

Hence, the equation of the line that passes through the points (-6,4) and (-2,2) is y - 4 = -1/2(x + 6)

remember, to transform an equation we need to apply any operation to both sides of the equation. otherwise the equality relation is destroyed.

we want to get the equating to look like " x = ..."

so, the "+ 39" is in the way.

we need to subtract 39, but as mentioned, we need to do this on both sides.

x + 39 = 74

x + 39 - 39 = 74 - 39

x = 35 in

the fig tree is therefore 35 in. that is 39 in shorter than 74 in (the orange tree).

The area of the part of the plane 5x + 3y + z = 15 that lies in the first octant is 15x^3/6 + 45x^2y/2.

Area is a measure of the size of a surface or the amount of space it takes up. It can be measured in square units such as square feet, square meters, or acres. Area is used to describe the size of a two-dimensional object or shape, and is often used when discussing the size of a plot of land, a room, or other geographical area.

The first octant is defined as the area in the three-dimensional Cartesian coordinate system where all the coordinates are positive. In this case, the equation 5x + 3y + z = 15 can be rearranged to solve for z: z = 15 - 5x - 3y. This new equation can then be used to find the area of the plane that lies in the first octant by integrating the equation over the area of the octant.

To solve for the area, we must first find the boundaries of the octant. Since all coordinates must be positive, the boundaries of the octant are x = 0, y = 0, and z = 0. The area of the plane that lies in the first octant is then computed using the triple integral:

Area = ∫∫∫ 0 0 0 15-5x-3y dzdydx

= ∫∫ 0 0 (15x + 45y)dydx

= ∫ 0 (15x^2/2 + 45xy)dx

= 15x^3/6 + 45x^2y/2

Therefore, the area of the part of the plane 5x + 3y + z = 15 that lies in the first octant is 15x^3/6 + 45x^2y/2.

The distance between the two people is changing at a rate of 3.2 mi/hr.

The distance between the two people can be calculated by using the Pythagorean theorem.

Let one person be at the origin (0, 0) and the other person be at (x, y). After 15 minutes, the first person will be at (3*15, 0) and the second person will be at (2*15*cos45, 2*15*sin45).

Using the Pythagorean theorem, the distance between them can be calculated as:

d = sqrt((3*15 - 2*15*cos45)^2 + (2*15*sin45)^2) = sqrt(225 + 225) = sqrt(450) = 21.213

The rate of change of distance is given by the formula d/t, where d is the distance and t is the time.

Step-by-step explanation:

In order to have negative correlation between two variables the covariance must be negative.

What is correlation?

The degree to which two variables are linearly related is expressed by the statistical concept of correlation (meaning they change together at a constant rate). It is a typical technique for outlining straightforward connections without stating cause and effect.

The correlation between two variables x and y is,

[tex]r = \frac{Cov(x, y)}{S_x*S_y}[/tex]

where,

Cov(x, y) is the covariance between x and y.

[tex]S_x[/tex] and [tex]S_y[/tex] respectively denotes the standard deviation of x and y.

If the correlation is negative then  r < 0.

Now r < 0

[tex]\frac{Cov(x, y)}{S_x*S_y} < 0\\Cov(x, y) < 0\\Sx > 0, S_y > 0[/tex]

If r < 0 the Cov(x, y) < 0.

For the given data the mean is 180.28 and the modal class is 177 - 185.

First finding mean:

For the class of 150 - 158, the class boundaries are 149.5 - 158.5.

Middle value = (150 + 158)/2 = 154

Frequency = 5

mean= 154 × 5 = 770

For the class 159 - 167, the class boundaries are 158.5 - 167.5

Middle value  = (159 + 167)/2 = 163

Frequency = 16

middle value.  frequency = 163 × 16 = 2608

For the class 168 - 176, the class boundaries are 167.5 - 176.5

Middle value = (168 + 176)/2 = 172

Frequency = 20

middle value.  frequency = 172 × 20 = 3440

For the class 177 - 185, the class boundaries are 176.5 - 185.

Middle value = (177 + 185)/2 = 181

Frequency = 21

middle value.  frequency  = 181 × 21 = 3801

For the class 186 - 194, the class boundaries are 185.5 - 194.5

Middle value (x_m) = (186 + 194)/2 = 190

Frequency = 20

middle value.  frequency  = 190 × 20 = 3800

For the class 195 - 203, the class boundaries are 194.5 - 203.5

Middle value  = (195 + 203)/2 =199

Frequency = 15

middle value.  frequency  = 199 × 15 = 2985

For the class 204 - 212, the class boundaries are 203.5 - 212.5

Middle value  = (204 + 212)/2=208

Frequency = 3

middle value.  frequency  = 208 × 3 = 624

Now in order to determine the mean of this group data all values calculated separately through the product of middle value and frequency will be added together and divided by the total frequency count (i.e 100).

That is

Mean =  ( 770 + 2608 + 3440 + 3801 + 3800 + 2985 + 624 ) = 18028 / 100

Mean  =   180.28
