Answer:

Yes, the mean cycle time is greater than 3.5 hours

Step-by-step explanation:

Let us try to calculate the mean cycle time here. Consider the given cycle times. To obtain the mean cycle time, we have.

3.45 + 3.47 + 3.57 + 3.52 + 3.40 + 3.62/6 = 3.505 hours

Hence the difference 3.505 -3.5 = 0.005

Hence mean cycle time is greater than 3.5 by 0.005

Answer: 0.023

Step-by-step explanation:

Given that:

Number of green balls = 9

Number of white balls = 8

Total number of balls = 9 + 8 = 17

Drawing with replacement :

Probability of white :

First draw = 8/17

2nd draw = 8/17

3rd draw =. 8/17

4th draw = 8/17

5th draw = 8/17

P(all 5 are white) = 8/17 * 8/17 * 8/17 * 8/17 * 8/17 = 32768/1419857

= 0.0230783

= 0.023

Answer: m=3 radical 2 and n=3

Answer:

The answer is 4(3x² + 1)(x - 5).

Step-by-step explanation:

First, you have to take out all the common ratios :

12x³ - 60x² + 4x - 20

= 4(3x³ - 15x² + x - 5)

Next, you have to factorize the inner brackets :

3x³ - 15x² + x - 5

= 3x²(x - 5) + (x - 5)

= (3x² + 1)(x - 5)

Answer:

4(3x² + 1)(x - 5)

Step-by-step explanation:

Given

12x³ - 60x² + 4x - 20 ← factor out 4 from each term

= 4(3x³ - 15x² + x - 5)

Factor the first/second and third/fourth terms inside the parenthesis

= 4[ 3x²(x - 5) + 1(x - 5) ] ← factor out (x - 5) from each term

= 4(3x² + 1)(x - 5)

Answer:

She paid for 8 classes

Step-by-step explanation:

Take away $35 from $155 because it was a one time custom fitting. And they’re asking for how many classes. So 35-155=120. Now you didvide 15 (charge per class) by 120 (total for all classes). And your answer is 8 classes. Hope this helped :)

Answer: Answer:

True

Step-by-step explanation:

No need for explanation

Answer:

it doesn't because there are places where there are two y values which just doesn't work out.

Dilation involves changing the size of a shape.

The true statement is that the locations of E' and F' are E' (−12, 0) and F' (0, 6), and lines g and g' are parallel.

The given parameters are:

[tex]k =3[/tex] --- the scale factor

[tex]E = (-4,0)[/tex]

[tex]F =(0,2)[/tex]

Multiply the coordinates of point E and F by the scale factor (k), to determine the new coordinates of E and F.

[tex]E' = E \times k[/tex]

[tex]E' = (-4,0) \times 3[/tex]

[tex]E' = (-12,0)[/tex]

[tex]F' = F \times k[/tex]

[tex]F' = (0,2) \times 3[/tex]

[tex]F' = (0,6)[/tex]

Given that line g is represented by points E and F; line g' would be represented by points E' and F'

So, both lines would be parallel.

Hence, the true option is (d)

Step-by-step explanation:

The solution to the inequality -3( 2j - 11 ) ≥ 8j - 9 can be represented in an inequality form or interval notation form as j ≤ 3 and (-∞,3] respectively.

Given the inequality in the question;

-3( 2j - 11 ) ≥ 8j - 9

First, we simplify using distributive property.

-3( 2j - 11 ) ≥ 8j - 9

-3×2j -3×-11 ≥ 8j - 9

-6j + 33 ≥ 8j - 9

Next, move all terms containing j to the left and all constant to the right.

-6j + 33 ≥ 8j - 9

-6j - 8j ≥ - 9 - 33

-14j ≥ -42

Divide both sides by -14.

Note that, when multiplying or dividing both sides of an inequality by a

negative value, the inequality sign flips directions.

-14j/-14 ≤ -42/-14

j ≤ -42/-14

j ≤ 3

Therefore, The solution to the inequality -3( 2j - 11 ) ≥ 8j - 9 can be represented in an inequality form or interval notation form as j ≤ 3 and (-∞,3] respectively.

Answer:

t = 15825.11 years

Step-by-step explanation:

From the given information:

We can make use of the activity of the sample present after time "t" to determine the age of the sample.

This can be expressed by the formula:

[tex]A = A_o e^{-\lambda t}[/tex] --- (1)

where;

[tex]A_o[/tex]= activity of the sample at time t = 0

[tex]\lambda[/tex] = disintegration constant

[tex]\lambda = \dfrac{0.693}{T_{1/2}}[/tex]

If we replace the value of [tex]\lambda[/tex]  into equation (1), we have:

[tex]A = A_o e^{ \Bigg [ -{ \dfrac{0.693}{T_{1/2}} \Bigg ] } t}[/tex]

[tex]\dfrac{A}{A_o} = e^{ \Bigg [ -{ \dfrac{0.693}{T_{1/2}} \Bigg ] } t}[/tex]

By rearrangement:

[tex]t = \dfrac{-T_{1/2} In (\dfrac{A}{A_o})}{0.693}[/tex]

[tex]t = - \dfrac{\left(5730\ \cdot\ \ln\left(\frac{\left(1770\right)}{0.8\cdot10^{3}\cdot15}\right)\right)}{0.693}[/tex]

t = 15825.11 years

Answer:1

Step-by-step explanation:x=1/2 , y =-1/2

X-y = 1/2-(-1/2)=1

Answer:

x-y = 1

Step-by-step explanation:

Question: Given x = 1/2 and y = -x, what is the value of x - y​?

Step-by-step:

We know that x = 1/2 and y = -x but we need to find out what -x is equal to.

To find the value of -x, we need to multiple -1 on both sides of the equation: x = 1/2

(You can think of it like -1 acts like an invisible number)

x*-1 = 1/2*-1 which is -x = -1/2

Since y is equal to -x, y = -1/2

We need to find x - y which is 1/2 - (-1/2)

Because the negative and subtraction signs cancel out, we add instead. The equation becomes 1/2 + 1/2

One half + half = 1

Therefore, x-y = 1

Answer:

The m<PML + m<PMQ + m<QMN = 180° since they are supplementary

therefore,

45°+(6x-5)+x=180°

45+7x-5=180

40+7x=180

7x=140

x=20

To test it we should plug in x for each equation and the sum of those answers should equal 180

45+(6x20-5)+20=180?

45+115+20=180?

160+20=180?

180=180

x=20 is valid

Answer:

88.88% or 8/9 of the yard is mowed

Step-by-step explanation:

First step is to get the denominator to the same number. Both denominators have a least common multiple of 12.

3/4 * 3/3 = 9/12

2/3 * 4/4 = 8/12

9/12 hours is how long it takes Evan to mow his backyard. He has 8/12 hours of work already done. If we divide the time already passed by the time still needed to mow the backyard, we can get how much of the yard is already mowed.

(8/12) / (9/12)

8/12 * 12/9  

96/108 = 88.88
