How do yo slove the problem

maksim [4K]

4) In triangle, angle opposite to perpendicular is 90-60 = 30
So, tan Ф = P/B
tan 30 = a / 6
1/√3 = a/6
a = 6/√3
a = 2√3

Now, cosФ = B/H
cos 30 = 6/b
√3/2 = 6/b
b = 6*2/√3
b = 12/√3
b = 4√3

In short, Your Answer would be a = 2√3 and b = 4√3

Hope this helps!

Answer:

a. C= 5/9(F-32)

Step-by-step explanation:

Answer:

(0.1392,0.1466)

Step-by-step explanation:

Given that a survey given to consumers leaving a supermarket three days before Thanksgiving asked whether turkey would be part of the Thanksgiving meal

People surveyed = 182

claimed not eating turkey = 26

Sample proportion = $\frac{26}{182} \\=0.1429$

Std error = $\sqrt{\frac{pq}{n} } \\=0.0260$

Margin of error = 1.96*SE= $0.00378$

Confidence interval = $(0.1429-0.0037,0.1429+0.0037)\\=(0.1392,0.1466)$
