Rasek [7]

Answer:

0.6604

Step-by-step explanation:

Given that a market  research firm knows from historical data that telephone surveys have a 36% response rate.

Sample size of random sample = 280

We know for samples randomly drawn of large size sample proportion follows a normal distribution with mean= sample proportin and std error

= \sqrt{\frac{pq}{n} }

Substitute p = 0.36 and q = 1-0.36= 0.64

p follows N with mean = 0.36 and std dev = \sqrt{\frac{0.36*0.64}{\sqrt{280} } } \\=0.0287

Using normal distribution values we can find\

P(33.5p.c. < p < 39pc)\\= P(0.335

sammy [17]

Answer:

The slant height is 13m

Step-by-step explanation:

The slant height of the cone, l , can be found using Pythagoras Theorem.

l^2=12^2+(\frac{10}{2})^2

l^2=12^2+(5)^2

l^2=144+25

l^2=169

l=\sqrt{169}

l=13m
