Answer:

Explanation:

P(skip or seven) = P(skip) + P(seven)

P(skip) = 8/108
P(seven) = 2/108

P(skip or seven) = 8/108 + 2/108
P(skip or seven) = 10/108 = 5/54

Therefore, the probability of drawing a skip or a seven is 5/54

How quickly do synthetic fabrics such as polyester decay in landfills? A researcher buried polyester strips in thes oil for diff
ad-work [718]

Answer:

no enough evidence to draw up a conclusion

Step-by-step explanation:

Data:

let: \mu _{1} = decay after 2 weeks

    \mu _{2} = decay after 16 weeks

Making the hypotheses:

Null hypothesis; H_{o} = \mu _{1}  - \mu _{2} = 0

the deviation = 0.05

the standard difference  = 4

Conditions:

The normal distribution curve can be plotted on a graph and the plot shows that the distribution is a skewed distribution.

Then,

t = \frac{(123.8-16.4)-0}{\sqrt{\frac{4.6^{2} }{5}+\frac{16.09^{2} }{5}   } } \\  = 0.989

Therefore, it can be concluded that 0.1983 > 0.05. This presents our failure to reject the null hypothesis.

Thus, there is not enough evidence to conclude that polyester decays more in less than 2 weeks.

Rewrite the following in the form log(c).<br> log(10) – log(5)
Svet_ta [14]

Answer:

log(2)

Step-by-step explanation:

In order to combine log(10) and log(5), you need to look at the sign that's combining them. In this example, it is a subtraction sign. When two logs are being subtracting from each other, it's the same as dividing the two. You would rewrite it like this:

log(10/5)

You would then solve 10/5, and get 2. You would rewrite the log as:

log(2)

Melanie has a piece of cloth 12 and 1/3 yards long. How many 3/4 yard-long pieces can be cut from the cloth?
Harrizon [31]
This is a division problem. First, get 12 1/3 into fraction form instead of mixed number form to make your life easier;  
12  \frac{1}{3} =  \frac{36}{3} +  \frac{1}{3} =  \frac{37}{3}  &#10;  
Now, divide the two fractions. Since this is fraction division, the reciprocal is flipped and the two fractions multiplied.  
\frac{37}{3} *  \frac{4}{3} =  \frac{148}{9} = 16  \frac{4}{9}  &#10;  
The answer from the fraction division is 16 and four-ninths, but because you need a whole number as an answer,  
the answer is 16 pieces.

102,119,107,113,110, x; mean 114
Rom4ik [11]

Answer:

x = 133

Step-by-step explanation:

First, determine what total sum would be needed for the mean to be 114. Do this by multiplying 114 by 6 (bc total number of values in data set includes the variable <em>x</em>).

114 x 6 = 684

Next, add the five known values to get a sum of 551.

Now, just: 684 - 551 = 133

For the mean to be 114, x must equal 133.
