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:

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.

Miles : 3/5
Hours : 1/3
_____ miles in 1 hour

Answers

Answer:

9/5 miles in 1 hour

Step-by-step explanation:

As we are finding here the miles distance in 1 hour so we have to use here the formula which is

Rate = Distance / Time

Rate = 3/5 divided by 1/3

SO using third proportion rule we have to change the Numerator of second fraction with denominator and denominator with numerator  and division sign will be change into Multiplication so this one will be

3/5 x 3/1

9/5 will be the answer

Brianna went into a bakery and bought 2 cookies and 3 brownies, costing a total of $9.50. Nevaeh went into the same bakery and bought 10 cookies and 6 brownies, costing a total of $20.50. Write a system of equations that could be used to determine the price of each cookie and the price of each brownie. Define the variables that you use to write the system.

Answers

Answer:

Variable x = cost of cookies

Variable y = cost of brownies

System of equations:

2x + 3y = 9.50

10x + 6y = 20.50

Step-by-step explanation:

Variable x: $ cookies

Variable y: $ brownies

2x + 3y = 9.50

10x + 6y = 20.50

Which of the following are accurate assessments of trends displayed in this graph?
I. Sales of teddy bears decreased by about 2.9% between September and October.
II. The change in sales of rabbits is roughly equal to the change in sales of all toys.
III. Roughly 24.1% fewer horses were sold in October than in September.

a. I and II
b. II only
c. I and III
d. III only

Answers

Answer:

✅ D. III only

got it right on the test⬇️

The correct statement is

Roughly 24.1% fewer horses were sold in October than in September.

What is Data?

Data refers to any information, regardless of how it is presented or represented. A data can be a numeric expression, a piece of text like a name or address, or it can be a number.

We have,

                       September         October      Trend

Teddy bears         346                   308       -10.98%

Rabbits                  297                    260       -12.46%    

Cats                       199                     285        +43.22%

Horses                  245                     186        -24.08%

Others                  225                     275         +22.22%

Total                     1,312                    1,314         +0.15

Now, Sales of teddy bears decreased by about 2.9% between September and October.

That reduced by around 11%, thus it is untrue.

II. The change in sales of rabbits is roughly equal to the change in sales of all toys.

It is untrue because variations in the sales of rabbits do not correspond to variations in the sales of all toys.

III. Roughly 24.1% fewer horses were sold in October than in September.

Yes, this is correct.

Find the perimeter of this semi-circle with diameter, d = 45cm. Give your answer rounded to 1 DP.

Answers

Answer:

P = 70.6 cm

Step-by-step explanation:

Given that,

The diameter of the semicircle, d = 45 cm

Radius, r = 22.5 cm

We need to find the perimeter of the semicircle. The formula for the perimeter of a semicircle is given by :

[tex]P=\pi r\\\\P=\pi \times 22.5\\\\P=70.6\ cm[/tex]

So, the required perimeter is 70.6 cm.

A parking lot costs $1300 a month to operate, and it spends $260 each
month for every car that parks there. The parking lot charges a monthly fee of
$450 to park a car. If n is the number of cars, which equation represents the
profit function of the parking lot?
A. p= 710n+ 1300
B. p = 710n- 1300
c. p= 190n - 1300
D. p= 190n + 1300
SUBMIT
A

Answers

Answer:

[tex]p = 190n - 1300[/tex]

Step-by-step explanation:

Given

[tex]Monthly = 1300[/tex]

[tex]Expenses = 260[/tex] per car

[tex]Charges = 450[/tex] per car

Required

Determine the profit

Let the number of cars be n. So:

Express on n cars is: 260n

Charges on n cars is 450n

The profit (p) is then represented as:

[tex]p = Charges - Expenses - Monthly\ Expenses[/tex]

[tex]p = 450n - 260n - 1300[/tex]

[tex]p = 190n - 1300[/tex]
