Answer:
[tex]\triangle LKJ \sim \triangle LHG[/tex]
Step-by-step explanation:
Let suppose that JK and GH are parallel to each other and the length of JK is a multiple of the length of GH ([tex]JK = m\cdot GH[/tex]), then we know that [tex]\angle H \cong \angle J[/tex] and [tex]\angle G \cong \angle K[/tex] by alternate internal angles and [tex]\angle L_{1} \cong \angle L_{2}[/tex] by opposite angles, then [tex]KL = m\cdot GL[/tex] and [tex]HL = m\cdot JL[/tex]. Lastly, we conclude that [tex]\triangle LKJ \sim \triangle LHG[/tex]

Complete question :
Cyber Monday Shopping A survey of 1000 U.S. adults found that 33% of people said that they would get no work done on Cyber Monday since they would spend all day shopping online. Find the 95% confidence interval of the true proportion.
Answer:
(0.301 ; 0.359)
Step-by-step explanation:
Sample size, n = 1000
Phat = 0.33
(1 - phat) = 1 - 0.33 = 0.67
Zcritical at 95% = 1.96
Confidence interval :
Phat ± margin of error
Margin of Error = Zcritical * sqrt[(phat(1 - phat)) /n]
Margin of Error = 1.96 * sqrt[(0.33 * 0.67) / 1000]
Margin of Error = 1.96 * 0.0148694
Margin of Error = 0.0291440
Lower boundary = (0.33 - 0.0291440) = 0.300856
Upper boundary = (0.33 + 0.0291440) = 0.359144
(0.301 ; 0.359)

[tex]\dfrac{-79}{126}[/tex]
Step-by-step explanation:
The given expression is :
[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}[/tex]
The LCM of 3,7,9 and 14 is 126
So,
[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}=\dfrac{42(-2)+18(5)+14(-8)+9(3)}{126}\\\\=\dfrac{-79}{126}[/tex]
So, the value of the given expression is equal to [tex]\dfrac{-79}{126}[/tex].
