Answer:

a)0.099834

b) 0

Step-by-step explanation:

To solve for this question we would be using , z.score formula.

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

A candy maker produces mints that have a label weight of 20.4 grams. Assume that the distribution of the weights of these mints is normal with mean 21.37 and variance 0.16.

a) Find the probability that the weight of a single mint selected at random from the production line is less than 20.857 grams.

Standard Deviation = √variance

= √0.16 = 0.4

Standard deviation = 0.4

Mean = 21.37

x = 20.857

z = (x-μ)/σ

z = 20.857 - 21.37/0.4

z = -1.2825

P-value from Z-Table:

P(x<20.857) = 0.099834

b) During a shift, a sample of 100 mints is selected at random and weighed. Approximate the probability that in the selected sample there are at most 5 mints that weigh less than 20.857 grams.

z score formula used = (x-μ)/σ/√n

x = 20.857

Standard deviation = 0.4

Mean = 21.37

n = 100

z = 20.857 - 21.37/0.4/√100

= 20.857 - 21.37/ 0.4/10

= 20.857 - 21.37/ 0.04

= -12.825

P-value from Z-Table:

P(x<20.857) = 0

c) Find the approximate probability that the sample mean of the 100 mints selected is greater than 21.31 and less than 21.39.

Answer:

6.7 %

which agrees with answer A in your list.

Step-by-step explanation:

If the standard volume is 1.5 cubic cm, and the measured volume is 1.6 cubic cm, then the difference between these two is :

1.6 - 1.5 = 0.1 cubic cm. and therefore the percentage error is given by:

0.1/1.5 = 0.066666...which corresponds to a rounding of 6.7%

Recall as well that percent error is always expressed as a positive number.

Answer:

-14

Step-by-step explanation:

The answer is -14 because:

1)  First, we need to know that:

negative x negative = positive

negative x positive = negative

positive x negative = negative

positive x positive = positive

2) -9 - 5 is negative times negative which makes it 9 + 5 = 14

3) Since the number with the negative sign is greater, the answer is -14

Answer:

6.7 * 10^7

Step-by-step explanation:

$4.15n - ($250 + $2.45n)

Now that we have our expression, let's set it greater than or equal to 0

$4.15n - ($250 + $2.45n) >= 0

Let's simplify the left side.

$4.15n - $250 - $2.45n >= 0.

Combine like terms.

$1.7n - $250 >= 0

Add $250 to both sides.

$1.7n >= $250

Divide both sides by $1.7

n >= 148

You would need to make 148 light sabers to make a positive profit.

Answer:

8000

Step-by-step explanation:

198 and 42 rounded to the nearest hundreths are 200 and 40. the product of 200 and 40 is 8000

The product of 198 and 42 rounded both numbers to the nearest ten

is 8000.

We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, Use rounding to estimate the product of 198 and 42.

Now, 198 rounded to the nearest ten is 200, and 42 rounded to the nearest ten is 40.

Therefore, The multiplication of 198 and 42 rounded to the nearest 10 is,

= 200×40.

= 8000.

We know that TV = TU + UV. Let's plug the values from the picture into our equation.

x + 25 = 9 + 2x + 28.

Let's combine like terms on the right side.

x + 25 = 2x + 37

Subtract 37 and x from both sides.

-12 = x

TV = x + 25 = -12 + 25 = 13

UV = 2x + 28 = 2(-12) + 28 = -24 + 28 = 4

Answer:

width= 20

length= 44

Step-by-step explanation:

we can say the width is x and the length is  2x+4 and there are 2 widths and two lengths. so 2x+4+2x+4+x+x=128, 6x+8 = 128 which means x=20 s0 the width is 20 and the length is 44

The length of the pickleball is 44 feet while the width is 20 feet.

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Pickleball is a shape of a rectangle.

Let's say the length of the pickleball is L and the width is W

Given that,

The length of a standard pickleball court is 4 feet more than twice the width.

So,

L = 2W + 4

Perimeter 2(L + W) = 128

By substitution,

2(2W + 4 + W) = 128

3W + 4 = 64

W = 20

And L = 2(20) + 4 = 44

Hence "The length of the pickleball is 44 feet while the width is 20 feet".

Step-by-step explanation:

Answer:

205.599 yards

Step-by-step explanation:

1 meter = 1.09361 yards

Multiply 188 meters by 1.09361 yards

188 meters = (1.09361 yards) x (188 meters)

                   = 205.599 yards

Answer:

Step-by-step explanation:

L is the midpoint of KM. So, length of KL = length of LM

KL = LM = 14x

KL + LM = KM

14x + 14x = 26x + 14 {add the like terms}

28x = 26x + 14   {subtract 26x form both sides}

28x - 26x = 14

          2x = 14   {divide both side by 2}

        2x/2 = 14/2

             x = 7

KL = 14x = 14*7

KL = 98

Answer:

[tex]\boxed{\tt m=0}[/tex]

Step-by-step explanation:

The slope formula is:

[tex]m=\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]

where (x₁, y₁) and (x₂,y₂) are the points on the line.

The points given are (-2,8) and (-22,8). Therefore,

[tex]x_{1}=-2\\y_{1}=8\\x_2=-22\\y_2=8[/tex]

Substitute the values into the formula.

[tex]m=\frac{8-8}{-22--2}[/tex]

Solve the numerator. Subtract 8 from 8.

[tex]m=\frac{0}{-22+2}[/tex]

Zero divided by any number is zero, so we automatically know the slope is zero.

[tex]m=0[/tex]

The slope of the line is 0

Answer: 0

Step-by-step explanation:

To find the slope, you need to use the formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. You use the given points to plug in and solve.

[tex]m=\frac{8-8}{-22-(-2)} =\frac{0}{-20}=0[/tex]

Now, we know that the slope is 0 meaning this is a horizontal line.

Answer:

Option C.

Step-by-step explanation:

We have the following inequality :

[tex]3d+6<A[/tex] (I)

In which :

[tex]d[/tex] : '' The daily temperature in degrees Fahrenheit ''

[tex]A[/tex] : '' The average temperature for the year ''

We first need to find the solution (the inequality related to the value of [tex]d[/tex]) given that we set [tex]A=54[/tex] °F ⇒

Using the equation (I) :

[tex]3d+6<54\\3d<48\\d<16[/tex]

We find that the ''[tex]d[/tex]'' variable (daily temperature in degrees Fahrenheit) is less than [tex]16[/tex] °F.

The option B and the option D give us an interpretation about the [tex]''A''[/tex] variable.

Only the options A and C give us an interpretion about the [tex]''d''[/tex] variable

Between A and C, the option C is a more accurate option (because 72°F is closer to 16°F).

We answer that the option C best interprets the solution.
