4’1= 4 feet and 1 inch
12 inches= 1 ft.
12(4)= 48 ; 48+ 1inch = 49 inches
1’10= 1 foot and 10 inches
1(12)= 12 + 10 = 22
49-22= 27 inches !

<h3>Answer:  2' 3"</h3>

In other words, it's 2 feet, 3 inches

=================================================

Work Shown:

Convert the 4'1" to purely inches only

4'1" = 4 ft, 1 inch

4'1" = 4 ft + 1 inch

4'1" = 48 inches + 1 inch

4'1" = 49 inches

Note how 4 ft = 4*12 = 48 inches

-------------------

Through similar steps, you should find that 1'10", aka 1 ft 10 inches, is equivalent to 22 inches

Subtracting the two quantities gets us

(4' 1") - (1' 10") = (49 inches) - (22 inches) = 27 inches

Now convert that to the format "feet,inches".

27 in = 24 in + 3 in

27 in = (24/12 ft) + 3 in

27 in = 2 ft + 3 in

27 in = 2 ft, 3 in

27 in = 2' 3"

Answer:

The 95 percent confidence interval for the true mean metal thickness is between 0.2903 mm and 0.2907 mm

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.96\frac{0.000586}{\sqrt{59}} = 0.0002

The lower end of the interval is the sample mean subtracted by M. So it is 0.2905 - 0.0002 = 0.2903 mm

The upper end of the interval is the sample mean added to M. So it is 0.2905 + 0.0002 = 0.2907 mm

The 95 percent confidence interval for the true mean metal thickness is between 0.2903 mm and 0.2907 mm

Consider a regular deck of cards with 52 cards in total. Four of a kind is a poker hand that contains all four cards of one rank
svet-max [94.6K]

Answer:

No.

Step-by-step explanation:

This is because if one event happens before the other, the odds of the other event happening will change due to less cards being left to pick from.

Consider the scenario where 4 of a kind all contained 10's from the deck.

The possibility of a full-house with a 10 in the pile would be zero if there were no 10's left after the four of a kind turn had been made. Thus, since the four of a kind affects the probability of the full house, and vice versa, they are both dependent on each other and hence not exclusive events.
