Answer:

0.98732

Step-by-step explanation:

Given that :

Mean = 10 minutes

Variance = 2 minutes

For less than equal 40 jobs

Mean (m) = 40 * 10 = 400 minutes

Variance = 2 * 40 = 80 minutes

Standard deviation (s) = √variance = √80

Converting hours to minutes

X = 60 * 7 = 420 minutes

P(X≤ 420) :

Z = (x - m) / s

P(X≤ 420) :

Z = (420 - 400) / √80

Z = 20 / √80 = 20 / 8.9442 = 2.236

P(Z ≤ 2.236) = 0.98732

The probability that the machine processes less than or equal should be 0.98732

Since

Mean = 10 minutes

Variance = 2 minutes

For less than equal 40 jobs

Mean (m) = 40 ( 10) = 400 minutes

Variance = 2 (40) = 80 minutes

Now

Standard deviation (s) = √variance = √80

Now here we Converting hours to minutes

So,

X = 60 (7) = 420 minutes

Now

P(X≤ 420) :

Z = (x - m) / s

Z = (420 - 400) / √80

Z = 20 / √80

= 20 / 8.9442

= 2.236

Now finally

P(Z ≤ 2.236)

= 0.98732

Hence, The probability that the machine processes less than or equal should be 0.98732

Answer:

Step-by-step explanation:

UW is the midsegment of ΔVXY,

By midsegment theorem of a triangle,

"Segment joining the midpoints of two sides of a triangle is parallel to the third side and measure of midsegment is half of the length of the third side."

UW = [tex]\frac{1}{2}(XY)[/tex]

Since, XY = 30 units

UW = [tex]\frac{1}{2}(30)[/tex]

      = 15 units

Therefore, length of the midsegment UW = 15 units will be the answer.

Step-by-step:

The sum of all multiples of 6 between 12 and 87 is equal to 624.

The multiples of 6 are of the form: 6*n

Where n is an integer.

The multiples between 10 and 87 are:

6*2 = 12

6*3 = 13

...

6*14 = 84

Then the sum of all these multiples can be written as:

[tex]6*2 + 6*3 + 6*4 + ... + 6*14\\\\= 6*(2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14) = 624[/tex]

The sum of all multiples of 6 between 12 and 87 is equal to 624.

Hey there!

“x – 3 < 2”

Let’s change your current question into a(n) equation to make it EASIER to solve (this is for temporary purposes ONLY)

• Temporary question

x – 3 = 2

• First: ADD BOTH SIDES by 3

x – 3 + 3 = 2 + 3

• CANCEL: –3 + 3 because that gives you 0

• KEEP: 2 + 3 because that helps solve for x

• New temporary question: 2 + 3 = x

2 + 3 = 5

The temporary question answer is: x = 5 ✅

NOW LETS SOLVE FOR YOUR ACTUAL EQUATION (just saying it REQUIRES the SAME steps as the temporary question just a TAD bit differently!)

x – 3 < 2

• FIRST: ADD both SIDES BY 3

x – 3 + 3 < 2 + 3

• CANCEL: –3 + 3 because that gives you 0

• KEEP: 2 + 3 because that helps us compare the answer with x

• New equation: x < 2 + 3

2 + 3 = 5

x < 5

Answer to your given question is: x < 5 ☑️

Answer:

Step-by-step explanation:

Given that :

Standard deviation (σ) = 5 minutes = (5 *60) = 300 seconds

Margin of Error, E = 78

Assume a confidence interval of 95%;

Using the relation :

((Zα/2 * σ) / E)²

(1 - α)/2 = (1 - 0.95)/2 = 0.05 /2 = 0.025

Z0.025 = 1.96

Sample size = ((1.96 * 300) / 78)²

Sample size = (588 / 78)^2

Sample size = 7.5384615^2

Sample size = 56.828

= 57 samples

Answer:

There are 56 ways to choose 5 from 8 varieties.

Step-by-step explanation:

a) Choosing 5 out of 8

This is a combination problem, given by the formula below:

C(n,r)=?

C(n,r)=C(8,5)

=8!/(5!(8−5)!)

= 56

b) A combination is the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed. The result of this combination of 5 out of 8 varieties shows that there 56 ways one can choose.  The formula is given by 8 factorial divided by (5 factorial by 3 factorial).
