Answer:

Odds in Favor = 1 / 5

Step-by-step explanation:

odds \: in \: favour  =  \frac{ number \: of \: observation \: satisfying \: given \: condition \: }{number \: of \: observation \: not \: satisfying \: given \: condition}

odds  =  \frac{1(observation -5)}{5(observations - 1,2,3,4,and \: 6}

Answer:

1/6 or 16.7% chance

Step-by-step explanation:

A die has 6 sides, and there is only one side with a number divisible by 5, which is the number 5.

So, the probability of rolling a number divisible by 5 is 1/6.

= 1/6 or 0.167

Triangle ABC has been reflected over the x-axis to create triangle A'B'C'. Which of the following statements is true?
Leto [7]

Answer:

A ' = (-2, -3)

B ' = (0, -3)

C ' = (-1, 1)

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

Explanation:

To apply an x axis reflection, we simply change the sign of the y coordinate from positive to negative, or vice versa. The x coordinate stays as is.

Algebraically, the reflection rule used can be written as

Applying this rule to the three given points will mean....

Point A = (-2, 3) becomes A ' = (-2, -3)

Point B = (0, 3) becomes B ' = (0, -3)

Point C = (-1, -1) becomes C ' = (-1, 1)

The diagram is provided below.

Side note: Any points on the x axis will stay where they are. That isn't the case here, but its for any future problem where it may come up. This only applies to x axis reflections.

Find area of parallelogram multiple choice
alina1380 [7]

In ∆ABD

\\ \sf\longmapsto Area=\dfrac{1}{2}bh=\dfrac{1}{2}(7\times 4)

In ∆BCD

\\ \sf\longmapsto Area=\dfrac{1}{2}(7\times 4)

Now

IN PARALLELOGRAM ABCD

\\ \sf\longmapsto Area=\dfrac{1}{2}(7\times 4)+\dfrac{1}{2}(7\times 4)

Let XXX and YYY be the following sets: X = \{9, 25\}X={9,25}X, equals, left brace, 9, comma, 25, right brace Y = \{1, 4, 9,16,25
Dmitry_Shevchenko [17]

Answer:

The answer is "\bold{ \{\phi\}}"

Step-by-step explanation:

Given value:

\ Set\ X  = \{9, 25\} \\\\\ Set \ Y = \{ 1,4,9,16,25 \}\\\\Find: \\\\Set (X- Y) \\\\

When we subtract set X - Y it means, that it will give only, that value which is not available on the set Y.

\{X-Y\} = \{\phi\}

In an auditorium, there are 21 seats in the first row and 29 seats in the second row. The number of seats in a row continues to
eimsori [14]

Step-by-step explanation:

a) The 3rd row has 37 seats, the 4th row has 45 seats and the 5th row has 53 seats.

b) This is an arithmetic sequence because the values differ by a constant quantity.

c) You need to find the nth term of the sequence:

    21 = 1×8+x

    x=13

So the nth term is 8x +13.

The 100th term would be 813.
