A bakery sells cakes, cookies, and pastries. They wonder if customers are equally likely to buy each product
They take a sample of 200 recent purchases and record what was purchased (they are willing to treat this as
a random sample). Here are the results:
Product
Observed purchases
Cakes
65
Cookies Pastries
68
67
They want to perform a x' goodness-of-fit test to determine if these results suggest that one type of
product is more popular than the others.
What is the expected count of cake purchases?
You may round your answer to the nearest hundredth.
Expected:

Answers

Answer 1

Answer: The expected count of cake purchases is 66.67 (rounded to the hundreths).

Step-by-step explanation:  Hypothesis the bakery is trying to find is if customers are equally likely to buy each product and since the sample is 200, we would have to equally split that between the 3 categories, so the expected counts for Cakes, cookies, and pastries would all be 66.67 (rounded to the hundreths).

Answer 2

The expected count of cake purchases would be 66.67 (rounded to the hundredths).

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The results are given as:

Product   Observed purchases

Cakes        65

Cookies    68

Pastries     67

To find if customers are equally likely to buy each product and since the sample is 200,

we would have to equally split that between the 3 categories,

The expected count of cake purchases = 200/3

= 66.67

Thus, the expected counts for Cakes, cookies, and pastries would be 66.67 (rounded to the hundredths).

Answers

Answer:

opposite angle of trapezoid is supplementary

<Z+<X=180°

<X=180°-72°

<x=108°

is your answer

The required value of the measure of the angle x is 108°. Option A is correct.


The following image is a trapezoid. if XW is congruent to YZ and measure of m = 72 degrees. calculate the measure of X is to be determined.

What is angle?

The angle can be defined as the one line inclined over another line.

What is a trapezoid shape?

A trapezoid is defined as a quadrilateral with one couple of opposite sides parallel. the sum of the opposite angles is 180. Only one pair of opposite sides should be parallel not all the sides if all sides are parallel then the shape became a rectangle or rhombus.



Since the sum of the opposite angles in trapezoids is 180°
so,
x + 72° = 180°
x = 180° - 72°
x = 108°

Thus, the required value of the measure of the angle x is 108°.

UV
and \text{m}\angle V = 71^{\circ}.m∠V=71

. Find \text{m}\angle U.m∠U.

Answers

Answer:

m∠U = 54.5°

Step-by-step explanation:

ΔUVW is an isosceles triangle.  The angles opposite UV and VW are congruent.

That means m∠U = m∠W

Since the measures of the angles of a triangle have a sum of 180, then

m∠U + m∠W + m∠V = 180

m∠U + m∠U + 71 = 180

2 m∠U = 109

m∠U = 54.5°

A certain map scale in which 1/2 inch on the map represents an actual distance of 10 miles. A distance of x miles is represented by how many inches on this map?

A certain map scale in which 1/2 inch on the map represents an actual distance of 10 miles. A distance of x miles is represented by how many inches on this map?

From the above question:

1/2 inch = 10 miles

x inches = m

Cross Multiply

1/2m = 10x

m = 10x ÷ 1/2

m = 10x × 2

From an angle of depression of 61 degrees, John

What is the distance between John's friend and the
building?
10.6
34.3
5.5
10.5

Answers

Answer:

10.53

Step-by-step explanation:

Given :

Height of building = 17m

John's eye level = 2 m

Total height (including eye level) = 17+2 = 19m

Angle of depression, θ = 61°

Let distance between John's friend and building = d

Using trigonometry :

Tan θ = opposite / Adjacent

Tan 61° = 19 / d

1.8040477 = 19 / d

d = 19 / 1.8040477

d = 10.53

Answers

Answer: 2x=74

Step-by-step explanation:

Every triangle is 180 degrees.

so you will take 180-32= 148

then with that you will add up the x's and there are 4...

so then you will take 148/4 and get the answer of...

148/4=37

x=37

A circle has a radius of 6 feet. Calculate the area of the
sector formed by a central 30° angle

Answers

Answer:

The area of the sector is 9.43 ft^2

Step-by-step explanation:

Here, we want to find the area of the sector with a central angle of 30 degrees

To do this, we use the formula below;

Area of sector = theta/360 * pi * r^2

theta = central angle = 30 degrees

r = radius = 6 ft

Thus, we have it that;

Area of sector = 30/360 * pi * 6^2

= 30/10 * pi = 3 * 3.142 = 9.43 ft^2
