Lisa is in charge of planning a reception for 3600 people. She is trying to decide which snacks to buy. She has asked a random s

Olenka [21]

Answer:

The expected number of the people at the reception whose favorite snack will be chips is 1152

Step-by-step explanation:

Given

The data in the above table and

Reception = 3600

Required

Predict the number of the people at the reception whose favorite snack will be chips.

The first step is to determine the total number of samples;

$Total = Brownies + Cookies + Chips + Other$

$Total = 32 + 22 + 56 + 65$

$Total = 175$

The next step is to determine the fraction of people whose favorite is chips

$Fraction = \frac{Chips}{Total}$

$Fraction = \frac{56}{175}$

The product of the above fraction and the expected number of people in the reception is the solution to this question;

$Expected\ Number = \frac{56}{175} * 3600$

$Expected\ Number = \frac{56* 3600}{175}$

$Expected\ Number = \frac{201600}{175}$

$Expected\ Number = 1152$

<em>Hence, the expected number of the people at the reception whose favorite snack will be chips is 1152</em>

In triangle ABC, if an exterior angle drawn at vertex C

Lorico [155]

Answer:

Part 1) Option D. must be an acute angle

Part 2) m∠A=70°

Step-by-step explanation:

Part 1) In triangle ABC, if an exterior angle drawn at vertex C measures 45, then angle B...

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles

The measure of an exterior angle at C is equal to the sum of the interior angles at A and B

we have that

45°=m∠A+m∠B

therefore

m∠B < 90°

Angle B must be an acute angle

Part 2)

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles

The measure of an exterior angle at B is equal to the sum of the interior angles at A and C

m∠A+m∠C=2m∠C+5

m∠C=m∠A-5 ----> equation A

m∠C=65° ----> equation B

substitute equation B in equation A

65°=m∠A-5

m∠A=(65+5)°=70°
