Answer:

From a standard deck of cards, one card is drawn. What is the probability that the card is black and a jack? P(Black and Jack) P(Black) = 26/52 or ½ , P(Jack) is 4/52 or 1/13 so P(Black and Jack) = ½ * 1/13 = 1/26 A standard deck of cards is shuffled and one card is drawn. Find the probability that the card is a queen or an ace.

Answer:

$\frac{2 \: + \: 3 \sqrt{5} }{3}$

Step-by-step explanation:

$\frac{2}{3} + \sqrt{5} =$

$= \frac{2}{3} + ( \sqrt{5} \times \frac{3}{3} )$

$= \frac{2}{3} + \frac{3 \sqrt{5} }{3}$

$= \frac{2 \: + \: 3 \sqrt{5} }{3}$

In ΔEFG, the measure of ∠G=90°, EF = 95 feet, and FG = 26 feet. Find the measure of ∠F to the nearest degree.

Firdavs [7]

Answer:

74.4°

Step-by-step explanation:

Given

∠G=90° => ΔEFG is a right triangle
EF = 95 feet
FG = 26 feet

Use sine law to find ∠F

As we know:

Sin(GEF)/ GF = Sin(EGF)/EF

<=> Sin(GEF) / 26 = Sin(90)/95

<=>Sin(GEF) / 26 = 1/95

<=> Sin(GEF) = 26/95

<=> ∠GEF ≈ 15.8°

=> ∠F = 180° - ∠G - ∠GEF

∠F = 180° - 90° - 15.8° = 74.4°
