The results of a poll show that between 74% and 82% of consumers prefer Chip A to Chip B. What is the point estimate for the percent of consumers that prefer Chip A to Chip B?

74%

78%

82%

8%

Answers

Answer 1

Answer:

78%

Step-by-step explanation:

First of all, the point estimate is a value located in between the upper confidence limit and the lower confidence limit, it identifies a point in some parameter space.

This question provides us with an interval estimate which is a range of values used to estimate a population parameter.

Interval Estimate = 74% to 82%

74% = Lower confidence limit

82% = Upper confidence limit

Point estimate = middle value

= [tex]\frac{74+82}{2}=\frac{156}{2}[/tex]

= 78%

1 hour 38 minutes

The team’s overall score is the average number of minutes it takes for its members to complete the course. What is this team’s score?

Answers

Step-by-step explanation:

the average is the sum of all data points divided by the number of data points (5).

2 hours 17 minutes

2 hours 48 minutes

1 hour 53 minutes

2 hours 19 minutes

1 hour 38 minutes

------------------------------

8 hours 175 minutes

175 minutes = 2 hours 55 minutes

so, we need to add this to the 8 hours and get

10 hours 55 minutes

this we need to divide by 5 for the average time

(10 hours 55 minutes) / 5 = 2 hours 11 minutes =

= 2×60 + 11 = 120 + 11 = 131 minutes.

so, their score is 131.

Step-by-step explanation:

Answer:

Julie travels 1.35 miles on the same path every day.

Area = 1.35 miles

Step-by-step explanation:

What we know so far:

- It takes 2.4 miles to walk from house to school.

- The distance from the park to school is 2.1 miles.

- It takes 1.5 miles to walk from your house to the park.

The area of a triangle is 0.5 or 1/2 x base x height.

As a result, 1.5 x 1.8 divided by two equals 1.35.

So, Julie walks 1.35 miles every day on the same route.

Area = 1.35 miles

The length of the line segment AM, which is a part of line segment AB when it is divided into two equal parts by Midpoint M is 14 units.

What is midpoint?

For a line segment, mid-point is the middle point of it which divides the line segment into the two equal parts.

Let assume "M" is the midpoint of the segment AB. The value of has to be found out. It is given that,

[tex]AM= x+7 \\MB=2x[/tex]

In this line segment AB, M is midpoint. Thus, it divide the line segment into two equal parts of AM and MB.  Thus,

[tex]x+7=2x\\2x-x=7\\x=7[/tex]

Put the value of x in AM,

[tex]AM=x+7\\AM=7+7\\AM=14\rm\; units[/tex]

A two-variable inequality is shown in the graph.



Which point is not included in the solution set for the inequality?

(–1, 3)

(1, 5)
(2, 4)

Answers

The point which is not included in the solution set for the inequality of the two-variable inequality shown in the graph is (-1,3).

How to graph the inequality?

Inequality of a graph is represented with the greater then(<), less then(>) or with the other inequity signs. The inequality line on the graph is represented with the dotted lines.

A two-variable inequality is shown in the graph. It is a parabola.  The vertex form of parabola is the equation form of quadratic equation which is used to find the coordinate of vertex points at which the parabola crosses its symmetry.

The standard equation of the vertex form of parabola is given as,

[tex]y=a(x-h)^2+k[/tex]

Here, (h, k) is the vertex point. In the graph, vertex points are (1,2). Thus, the equation become,

[tex]y=a(x-1)^2+2\\[/tex]

By the point of graph (0,3), find the value of a,

[tex]3=a(0-1)^2+2\\3=a+2\\a=3-2\\a=1[/tex]

Thus, the equation become,

[tex]y=1(x-1)^2+2\\y=x^2-2x+1+2\\y=x^2-2x+3\\[/tex]

The graph of this line is attached below. In this graph only point (-1,3), does not fall hence, does not satisfy the equation.

Thus, the point which is not included in the solution set for the inequality of the two-variable inequality shown in the graph is (-1,3).
