Step-by-step explanation:

In circle with centre O, TN is tangent at E.

\therefore OE \perp TN\\\\\therefore m\angle OET = m\angle OEN= 90\degree \\\\In\: \triangle OET\\\\\angle OET + \angle OTE +\angle TOE = 180°\\\\\therefore 90\degree + 35\degree+\angle TOE = 180°\\\\\therefore 125\degree+\angle TOE = 180\degree\\\\\therefore \angle TOE = 180\degree-125\degree\\\\\huge \red {\boxed{\therefore \angle TOE = 55\degree}} \\\\In\: \triangle OPE\\\\OP = OE... (radii\: of \:same \: circle) \\\\\therefore \angle OPE = \angle OEP..(1)\\  (\angle s \: opposite \: to \:equal\:sides) \\\\\angle TOE =\angle OPE +\angle OEP.. (2)\\(by\:exterior \:\angle\:theorem) \\\\\therefore 55\degree= \angle OPE +\angle OPE\\\{From\: equations\:(1) \&\:(2)\} \\\\\therefore 55\degree= 2\angle OPE \\\\\therefore \angle OPE = \frac{55\degree}{2}\\\\\huge \orange{\boxed{\therefore \angle OPE =27.5\degree}}

Which is the best buy?
sesenic [268]
3 bottles of juice
6.72/3 = $2.24 < amount paid for each bottle

11 bottles of juice
24.86/11 = $2.26 <amount paid for each bottle

9 bottles of juice
20.25/9 = $2.25 < amount paid for each bottle

16 bottles of juice
35.68/16 = $2.23 < amount paid for each bottle

*the best buy would be to get 16 bottles for $35.68*




10 bars of soap
23.20/10 = $2.32 < amount for each bar of soap

16 bars of soap
36.48/16 = $2.28 < amount for each bar of soap

13 bars of soap
29.51/13 = $2.27 < amount paid for each bar of soap

12 bars of soap
27.60/12 = $2.30 < amount for each bar of soap

*the best buy would be to get 13 bars of soap for $29.51*

hope this helps :)

Mrs. avery is going to randomly select one student from her class to read a poem out loud. there are 151515 boys and 131313 girl
arlik [135]
P(boy) is asking for the probability that a boy will be chosen to read a poem out loud. Since there are 15 boys, we can get the probability by dividing this with the total number of students. This is because out of all the students, there is an equal possibility that each of the 15 boys will be chosen.

\frac{15}{15+13}= \frac{15}{28}=0.5357

ANSWER: The probability that a boy is selected is 0.5357 or 53.57%

Fifteen people have been exposed to a particular disease. Each one independently has a 40% chance of contracting the disease. A
valina [46]

Answer: e. .0950

Step-by-step explanation:

Let X be the number of people that can be cure from disease.

Since each people independently has a 40% chance of contracting the disease.

So , X\sim Binomial(n=15,p=0.40)

A hospital has the capacity to handle at most 8 cases of the disease.

Binomial distribution formula : P(X=x)= ^nC_xp^x(1-p)^{n-x}

Then , the probability that the hospital’s capacity will be exceeded

P(X>8)=1-P(X\leq8)\\\\=1-0.905\ \ [\text{Using Binomial distribution table for n=15 , x=8 and p=0.4.}]

=0.095

Hence, the probability that the hospital’s capacity will be exceeded is e. .0950.

Thus , the correct option is e. .0950.
