Cards are selected from a standard deck of 52, the results are recorded in the table. what is the empirical probability of not s
Cerrena [4.2K]

The table have the following results:

 

Hearts – 7

Diamonds – 4

Clubs – 8

Spades – 5

There is a total of 24

 

The question is asking for the probability of not selecting a heart.

So we need to add the probabilities of the diamonds, clubs, and spades since these suits are different from hearts.

So = 4 + 8 + 5 = 17

And we have a total of 24 cards

<span>Therefore the probability is 17/24. </span>

john scored 15 points his first game. In his last game he scored 20 points. What was his percent of increase?
iVinArrow [24]

\huge\mathrm{ \it{Answer࿐}}

  • Increase = 20 - 15 = 5 points

  • \boxed{ \% \: increase \:  = \frac{5}{15} \times 100  }

  • \% \:  \:increase  =  \frac{100}{3}

  • \% \:  \:increase  = 33.33

Help pls 25 points i don’t understand
Brums [2.3K]

Calm Down this is a nasty proof

CB is parallel to ED (Given)

CB is congruent to ED (Given)

Angle CBF is congruent to Angle EDF (Vertical Angles)

Angle DEF is congruent to Angle BCF (Alternate Interior Angles)

Angle EDF is congruent to Angle CBF (Alternate Interior Angles)

Therefore we now have enough information to solve.  We have a side angle side triangle here so.....

Triangle CBF is congruent to Triangle EDF because of the Side Angle Side Theorem.

Good Luck and Your Welcome
