Answer:

a)

The probability that an individual distance is greater than  210.00 cm is 0.1056

b)

The probability that the mean for  25  randomly selected distances is greater than  198.70 cm is 0.7917

c)

The normal distribution be used in part​ (b), even though the sample size does not exceed​ 30 since the parent population from which the sample has be obtained is Normal.

Step-by-step explanation:

a)

We let the random variable X denote the overhead reach distances of individual adult females. This implies that X is normally distributed with a mean of 200 cm and a standard deviation of 8 cm.

The probability that an individual distance is greater than 210 can be written as;

Pr(X>210)

We standardize the value to obtain the associated z-score;

[tex]P(X>210)=P(Z>\frac{210-200}{8})=P(Z>1.25)[/tex]

Using the standard normal tables, the area to the right of 1.25 is 0.1056. Therefore, the probability that an individual distance is greater than  

210.00 cm is 0.1056.

b)

The first step will be to determine the sampling distribution of the sample mean given that the variable overhead reach distance is normally distributed with a mean of  200 cm and a standard deviation of  8 cm.

In this case, the sample mean will also be normally distributed with a mean of 200 cm and a standard deviation of;

[tex]\frac{sigma}{\sqrt{n} }=\frac{8}{\sqrt{25} }=1.6[/tex]

The probability that the mean for  25  randomly selected distances is greater than  198.70 cm;

Pr(sample mean >198.70)

We standardize the value to obtain the associated z-score;

[tex]=P(Z>\frac{198.70-200}{1.6})=P(Z>-0.8125)[/tex]

Using the standard normal tables, the area to the right of -0.8125 is 0.7917. Therefore, the probability that the mean for  25  randomly selected distances is greater than  198.70 cm is 0.7917.

c)

The normal distribution be used in part​ (b), even though the sample size does not exceed​ 30 since the parent population from which the sample has be obtained is Normal.

A decrease by 30%, means that the price is now 70% of the original price ( 100% - 30% = 70%)

To find the original price divide the new price by the percent of the original price it is now.

147 / 0.70 = 210

The original price was £210

The price before the decrease is £210.

Given that,

Based on the above information, the calculation is as follows:

[tex]= 147 \div 70\%[/tex]

=  £210

Therefore we can conclude that the price before the decrease is £210.

width of the crate = 2 units

Height of the crate = 4 units

Since the crate has been packed packed with the unit cubes.

Therefore, shape of the crate will be in the form of a rectangular prism.

Volume of the prism = Length × width × height

                     crate     = 4 × 2 × 4

Answer:

[tex]\frac{dy}{dx} = \frac{cos(x+y)}{1-cos(x+y)}[/tex]

Step-by-step explanation:

We have the function [tex]y=sin(x+y)[/tex]

We need find the derivative of y with respect to x

Note that the function [tex]y = sin (x + y)[/tex] depends on the variable x and the variable y. Therefore the derivative of y with respect to x will be equal to the derivative of [tex]sin (x + y)[/tex] by the internal derivative of  [tex]sin (x + y)[/tex]

[tex]\frac{dy}{dx}= cos(x+y)*\frac{d}{dx}(x+y)[/tex]

[tex]\frac{dy}{dx}= cos(x+y)*(1+\frac{dy}{dx})\\\\\frac{dy}{dx}= cos(x+y)+\frac{dy}{dx}cos(x+y)\\\\\frac{dy}{dx} -\frac{dy}{dx}cos(x+y)=cos(x+y)\\\\\frac{dy}{dx}(1-cos(x+y))=cos(x+y)\\\\\frac{dy}{dx} = \frac{cos(x+y)}{1-cos(x+y)}[/tex]

Answer:

Step-by-step explanation:

Note that y=sin(x+y) is an implicit function; y appears on both sides of the equation, which makes it difficult or impossible to solve for y.

However, our job here is to find the derivative dy/dx.

We apply the derivative operator d/dx to both sides.  Here are the results:

dy

---- = cos(x + y)(dx/dx + dy/dx), or

dx                                                         Note:  dx/dx = 1

dy

---- = cos(x + y)(1 + dy/dx), or  = cos(x + y) + cos(x + y)(dy/dx)

dx

We move that cos(x + y)(dy/dx) term to the left side to consolidate dy/dx terms:

dy

----  -  cos(x + y)(dy/dx) = cos(x + y)

dx

or:

 dy

[ ---- ] [ 1 -  cos(x + y) ] = cos(x + y)

  dx

Finally, we divide both sides by [ 1 -  cos(x + y) ], obtaining the derivative:

 dy            cos(x + y)

[ ---- ]  -------------------------

  dx         1 -  cos(x + y)

Find the area of the base B

[tex]B=\frac{1}{2}(3)(4)=6\ yd^{2}[/tex]

we have

[tex]H=7\ yd[/tex]

substitute the values in the formula

[tex]V=BH[/tex]

[tex]V=(6)(7)=42\ yd^{3}[/tex]

Answer:

The answer is 42 yards! Sry im late. :(

For this case we must find the value of the variable "x" of the following equation:

[tex]5x (4-2) = 20[/tex]

We solve the operation within the parenthesis:

[tex]5x (2) = 20[/tex]

We multiply the left side:

[tex]10x = 20[/tex]

We divide both sides of the equation by 10:

[tex]x = \frac {20} {10}\\x = 2[/tex]

ANswer:

[tex]x = 2[/tex]

The solution of the expression given for x is 2.

Given is an expression 5x(4-2) = 20, we need to solve for x.

To solve the expression 5x(4-2) = 20 step by step, follow these steps:

Simplify the expression inside the parentheses:

5x(4 - 2) = 20

5x(2) = 20

Multiply 5x by 2:

10x = 20

Divide both sides of the equation by 10 to isolate x:

(10x)/10 = 20/10

x = 2

Therefore, the solution for x is 2.

$0.13 per ounce.  5 pounds of birdseed cost $10.40, then the price per ounce is $0.13.

The easiest way to solve this problem is using arithmetic operations and unit conversion.

We have to calculate the price per pound. Let's divide $10.40 by 5 pounds.

10.40/5 = 2.08

The price per pound is $2.08

To calculate the price per ounce, with 1 pound = 16 ounces. Let's divide $2.08 by 16 ounces.

2.08/16 = 0.13

The price per ounce is $0.13

sin=√17/7

or sin=sqrt(17)/7

Answer:

[tex]\frac{\sqrt{17} }{7}[/tex]

Step-by-step explanation:

Given

cosΘ = [tex]\frac{4\sqrt{2} }{7}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]

Then the hypotenuse of the right triangle is 7 and the adjacent side is 4[tex]\sqrt{2}[/tex]

To find the opposite side use Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

opp² + (4[tex]\sqrt{2}[/tex] )² = 7²

opp² + 32 = 49 ( subtract 32 from both sides )

opp² = 17 ( take the square root of both sides )

opp = [tex]\sqrt{17}[/tex]

Hence

sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{\sqrt{17} }{7}[/tex]

To find the distance of objects sighted at angles of 29 degrees and 59 degrees, use the function d = 93 sec(theta). Substituting theta values, the distances are 106.87 feet and 166.39 feet, respectively.

To find the distance of an object sighted at angles of 29 degrees and 59 degrees, we can use the function given, d = 93 sec(theta). Substituting theta = 29 degrees, we get d = 93 sec(29) = 93*(1/cos(29)) = 93/0.8714 = 106.87 feet. Similarly, substituting theta = 59 degrees, we get d = 93 sec(59) = 93*(1/cos(59)) = 93/0.5588 = 166.39 feet.

To solve the system of equations x − y = 5 and 2x − 3y = 4, we can use the method of substitution or elimination. By substituting the value of x from the first equation into the second equation, we can find the value of y. Then, substitute the value of y back into the first equation to find the value of x. The solution to the system of equations is (11, 6).

To solve the system of equations x − y = 5 and 2x − 3y = 4, we can use the method of substitution or elimination. Let's use the method of substitution:

From the first equation, we can rearrange it to x = y + 5. Now substitute this value of x into the second equation:

2(y + 5) − 3y = 4

Simplify and solve for y:

2y + 10 - 3y = 4

-y + 10 = 4

-y = -6

y = 6

Now substitute this value of y back into the first equation to find x:

x − 6 = 5

x = 11

Therefore, the solution to the system of equations is (11, 6). So, the correct answer is option D.

Answer:

For number 14, the answer should be 100 degrees. For number 15, the answer is 80 degrees. For number 16, the answer is 120 degrees.

Step-by-step explanation:

For number 14, if a minor arc is 80 degrees, then the major arc should be 100 degrees to add to make 180 degrees. For number 15, you can see the size of the 70 degrees angle, AB. Because DE is bigger than AB, we can conclude that it is probably 80 degrees. For number 16, if XY, YZ, and ZX are all the same, and a circle always adds up to 160 degrees, then 360 divided by the three arcs is 120.
