What's the probability a dealer deals himself an ace on the first deal?

1 answer:

8 0

There are 52 cards in a deck. There are four aces.

Therefore,

Probability of dealing an ace = P(A)

$P(A) = \frac{4}{52} = 0.07692307692 = 7.692307692 \%$

Determine if the relation is a function if so state the domain and range

Sedaia [141]

Answer:

Function - Yes

Domain - [-3,0,3,4]

Range - [1,2,2,5]

Step-by-step explanation:

In a function, x-values cannot repeat and in this relation, x's do not repeat, therefore it is a function. The domain is the x-values on the graph from least to greatest; so to find the domain, simply take the first value of each coordinate and order them from least to greatest. Then, the range is the y-values, so to find the range take the second value from each coordinate and order them from least to greatest.

Difine complex fraction . give two example of a complex fraction

marin [14]

If in a fraction, the numerator or the denominator or both are fractions, then it is called a complex fraction.

Example 1:

$\frac{\frac{3}{4} }{7}$

Here, since the numerator is a fraction, it is a complex fraction.

Example 2:

$\frac{\frac{1}{2} }{\frac{3}{7} }$

Here, since the numerator and the denominator are fractions, it is a complex fraction.

Cos theta=8/17. Find tan theta A. 15/8 B. 15/17 C. 17/15 D. 8/15

Natalija [7]

Answer:

A) $\frac{15}{8}$

Step-by-step explanation:

remember Soh Cah Toa!!

$sin=\frac{opposite}{hypotenuse}\\ cos=\frac{adjacent}{hypotenuse} \\tan=\frac{opposite}{adjacent} \\\\cos=\frac{8}{17}\\\\a^2+b^2=c^2\\8^2+b^2=17^2\\64+b^2=289\\b^2=225\\\sqrt{b^2} =\sqrt{225}\\b=15=opposite\\\\tan=\frac{15}{8}$

. Solve for x 5x – 7 = 19 Give your answer as an

kipiarov [429]

5x - 7 = 19

Add 7 to both sides:

5x = 26

Divide both sides by 5:

x = 26/5
