The mean length of 9 childrens' big finger is 6.8cm.
The mean length of 3 adults' big finger is 11cm.
What is the mean length (rounded to 2 DP) of these 12 people's big finger?

Answers

Answer 1

Answer:

The mean length of these 12 people's big finger is of 7.85 cm.

Step-by-step explanation:

Mean value:

Sum of the values of all observations divided by the number of observations.

In this question:

9 + 3 = 12 total observations

Sum:

[tex]9*6.8 + 3*11 = 94.2[/tex]

So

[tex]M = \frac{94.2}{12} = 7.85[/tex]

The mean length of these 12 people's big finger is of 7.85 cm.

Ticket sales for the next two days are 55 tickets and 68 tickets. Which statement about the data is true?



a
The range stays the same.
b
The range increases by two.
c
The range decreases.
d
The range doubles.

Answers

B cuz it says the answer

Ticket sales for the next two days are 55 tickets and 68 tickets. The range doubles. The correct option is d.

What is Range?

The range of a dataset is the difference between the highest and lowest values. The highest value here is 68, and the lowest value is 55. As a result, the range is 68 - 55 = 13.

The range in statistics refers to the difference between the highest and lowest values in a dataset. It is a measure of dispersion that indicates how dispersed the data is.

The range is a quick and simple way to determine how much variability exists in a dataset. It is, however, influenced by outliers or extreme values in the dataset.

The range doubles because the highest and lowest values are the same on both days.

Thus, the correct option is d.

The perimeter of qudrilateral ABCD, to the nearest tenth is: 14.6 units.

What is the Perimeter of a Quadrilateral?

Perimeter of a quadrilateral = sum of all its four sides.

Given the qudrilateral with the vertices:

A (3, 5)B (1, 3)C (3, -1)D (5, 3)

Use the distance formula, [tex]d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex] to find AB, BC, CD, and AD.

AB = √[(1−3)² + (3−5)²]

AB = √8 = 2.8 units

BC = √[(1−3)² + (3−(−1))²

BC = √20 = 4.5 units

CD = √20 = 4.5 units

AB = √8 = 2.8 units

Perimeter of qudrilateral ABCD = 2.8 + 4.5 + 4.5 + 2.8 = 14.6 units.

Horatio recorded the daily high temperatures. On 66 days, the high temperature was greater than 88°F. This was 75% of the days that Horatio recorded. How many days was the high temperature less than or equal to 88°F?

Answers

Answer:

The answer is 22

Step-by-step explanation:

The total number of days recorded by Horatio was 88,

The number of days with high temperatures less than or equal to 88°F is 22 days.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We know that the high temperature was greater than 88°F on 75% of the days, which means it was less than or equal to 88°F on the remaining 25% of the days.

So we can set up an equation to solve for the number of days the high temperature was less than or equal to 88°F:

So,

25% x total number of days = number of days with high temperature less than or equal to 88°F

Or in other words:

0.25 x total number of days = number of days with high temperature less than or equal to 88°F

We are given that the number of days with high temperatures greater than 88°F is 66.

Let's use x to represent the total number of days:

0.25x = number of days with high temperature less than or equal to 88°F

0.25x = x - 66

(since the number of days with high temperatures less than or equal to 88°F is the remainder)

0.25x - x = -66

-0.75x = -66

x = 88

The total number of days recorded by Horatio was 88,

The number of days with high temperatures less than or equal to 88°F.

= 0.25 x 88

= 22 days.

Thus,

The total number of days recorded by Horatio was 88,

The number of days with high temperatures less than or equal to 88°F is 22 days.
