Answer:

The solution to these question can be defined as follows:

Step-by-step explanation:

H_0: \mu = 33 \ versus\\\\ H_a: \mu > 33\\\\\bar{X} = 33.11\\\\S = 4.7468\\\\n = 47\\\\df = n - 1 = 46\\\\\alpha = 0.05\\\\

Testing statistic:

t = \frac{(\bar{X} - \mu)}{[\frac{S}{\sqrt{(n)}}]}

= \frac{(33.11 – 33)}{\frac{4.7468}{\sqrt{47}}}\\\\= \frac{0.11}{0.6924}\\\\= 0.1589\\\\P-value = 0.4372\\\\P-value > \alpha = 0.05

Therefore the null hypothesis we do not deny, it is not clear enough so that the median age once British men get engaged is higher than in 2013.

Deborah has two paintings in her portfolio and paints three more each week.Kai has twelve paintings in her portfolio and paints
elena-14-01-66 [18.8K]
Well, we can set up these equations like this-
Deborah- 2+3w
Kai- 12+2w
w=number of weeks that pass
Now, we set them equal to each other:
2+3w=12+2w

Solve for w
2-12=2w-3w
-10 = -1w
w = 10
10 weeks. Hope this helped!

((2t+10) / 2) + ((3t-15) / 2) + (3s) = 180 
((2t+10) / 2) + ((3t-15) / 2) + (4r) = 180
((2t+10) / 2) + ((3t-15) / 2) + (3s) = ((2t+10) / 2) + ((3t-15) / 2) + (4r) 
(2t+10) = (3t-15)   t=25
2*25+10= 60  ,   3*25-15=60
60+60= 120 ,   This rectangle has a total of 360 degrees 
360 - 120 = 240
240/2 =120
120/ 4 = 30  ,  120/3 = 40
r=30    s=40
