Answer:

0.50

Step-by-step explanation:

There are two outcomes when flipping a coin, heads or tails, and one of them is heads so the probability is 1/2 = 0.50.

A coin has two sides. The probability of getting either side would be 1/2

1/5 as a decimal is 0.5

The probability of getting heads would be 0.5, place the x on 0.5

topjm [15]

Answer:

The answer is "0.142466".

Step-by-step explanation:

Using the p formula for the proportion of nonconforming units through the subgrouping which can vary in sizes:

$p =\frac{np}{n}\\\\$

$\bar{p}=\frac{\Sigma np}{\Sigma n}\\\\$

Defects $= \frac{5}{100} \times 50 \\\\$

$p = \frac{5}{100} \times \frac{50}{50}=0.05\\\\$

It calculates the controls limits through the p-chart that is:

$UCL_{p},LCL_{p}=\bar{p} \pm \sqrt{\frac{\bar{p}(1-\bar{p})}{\bar{n}}}\\\\$

So, the upper control limits:

$= 0.05 + 3 \times \sqrt{(\frac{0.05\times(1-0.05)}{50})} \\\\= 0.142466$

The 16th term of an AP is three times the 5th term.If the 12th term is 20 more the 7th term.Find the first term and the common d

Vlad1618 [11]

<h3>Answer:</h3>

First term = 6
Common difference= 4

<h3>Solution:</h3>

Let's take the first term as a and the common difference be d

The formula to find the nth term of an arithmetic progression is given by :

an = a + ( n - 1 ) d

According to question, we have :

16th term of an AP is three times the 5th term.

➝ a16 = 3 ( a5 )

➝ a + ( 16 - 1 )d = 3 ( a + ( 5 - 1 )d )

➝ a + 15d = 3 ( a + 4d )

➝ a + 15d = 3a + 12d

➝ 15d - 12d = 3a - a

➝ 3d = 2a

➝ 2a = 3d

➝ a = 3d/2‎ㅤ‎ㅤ‎ㅤ⸻ ( 1 )

And, the 12th term is 20 more the 7th term.

➝ a12 - ( a7 ) = 20

➝ a + ( n - 1 )d -( a + ( n - 1 )d ) = 20

➝ a + ( 12 - 1 )d - + a + ( 7 - 1 )d ) = 20

➝ a + 11d - ( a + 6d ) = 20

➝ a - a + 11d - 6d = 20

➝ 5d = 20

➝ d = 20/ 5

➝ d = 4

Using equation ( 1 )

➝ a = 3d / 2

➝ a = ( 3 × 4 ) / 2

➝ a = 12 / 2

➝ a = 6

Find the midpoint of the line on the coordinate plane with the given endpoints below.

tigry1 [53]

Answer:

Then the midpoint is (2, -2)

Step-by-step explanation:

We treat the x- and y-coordinates separately, first finding the average (mean) of the x-coordinates and then the average of the y-coordinates:

xm = (-1 + 5)/2 = 2

ym = (1 - 5)/2 = -2

Then the midpoint is (2, -2)

Hello can you please help me posted picture

shutvik [7]

First taking into account the if he buys in order.

Brian has 10 choices for the first selection of fish, 9 for the second selection and 8 for the third selection.

Thus you have 10*9*8 = 720 possible ways

However the question did not specify if it is in order. Now counting how many possible orders for each selection you can have

fish 1 , fish 2 , fish 3 or
fish 1 , fish 3 , fish 2 or
fish 2 , fish 1 , fish 3 or
fish 2 , fish 3 , fish 1 or
fish 3 , fish 1 , fish 2 or
fish 3 , fish 2 , fish 1 or

We have 6 order.

dividing the possible ways by the order we have 720 / 60 = 120

The answer is B. 120
