Answer:

\large\boxed{x=\dfrac{1}{2}=0.5}

Step-by-step explanation:

15-0.5(4x-2)+4x=17\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\15+(-0.5)(4x)+(-0.5)(-2)+4x=17\\\\15-2x+1+4x=17\qquad\text{combine like terms}\\\\(-2x+4x)+(15+1)=17\\\\2x+16=17\qquad\text{subtract 16 from both sides}\\\\2x+16-16=17-16\\\\2x=1\qquad\text{divide both sides by 2}\\\\\dfrac{2x}{2}=\dfrac{1}{2}\\\\x=\dfrac{1}{2}

Solve for x. Round to the nearest hundredth.
Airida [17]

Answer: 32.98^{\circ}

Step-by-step explanation:

Since, By the given diagram,

In quadrilateral ABCD, all angles are right angles ⇒ DC = AB = 15 cm and CB = DA

Also, In triangle DFA,

sin 56^{\circ} = \frac{DA}{DF}

⇒ sin 56^{\circ} = \frac{DA}{16}

⇒ 16\times sin 56^{\circ}=DA

⇒ 13.2646011609\text{ cm} = DA

Now, In triangle, DEC,

tan x = \frac{EC}{DC}

⇒ tan x = \frac{EB-CB}{DC}

⇒ tan x = \frac{EB-DA}{DC}

⇒ tan x = \frac{23-13.2646011609}{15}  

⇒ tanx = \frac{9.73539883912}{15}

⇒ tanx = 0.64902658927

⇒ x = 32.9846428556^{\circ} \approx 32.98^{\circ}

Bezzdna [24]

Answer:

.8

Step-by-step explanation:

S= studies for

B= score of b or higher

we want P(S|B)

Using Bayes' theorem we can solve for the probability

S|B=\frac{B|S*S}{B|S*S+B|S'*S'}=\frac{.55*.6}{.55*.6+.2*.4}=0.80487804878
