Answer:
- Mode-The most repetitive number.
- Median:The number in the MIDDLE when they are IN ORDER.
- Mean- The AVERAGE OF ALL NUMBERS: You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS.
- Range - THE BIGGEST minus the Smallest.
Step-by-step explanation:
;)
Answer:
mean: average of all the numbers, so add all numbers, divide by the amount of numbers you added
median: sort all the numbers from least to greatest, then the middle is the answer, if there are 2 in the middle, both are the answer
mode: the number that appeared most
range: the largest number minus the smallest number
Con k expresion decimal se corresponden los siguientes porcentajes a.Pequeños agricultores :45 b.Pasto para ganado :25 c.Agricultora a gran escala :20 d.Explotacion forestal:10
Respuesta:
0,45
0,25
0,20
0,10
Explicación paso a paso:
Para convertir un porcentaje dado a decimal; el valor dado se divide por 100;
Es decir ; el equivalente decimal de x% será: x / 100
Por lo tanto, convertir los porcentajes dados a decimal:
una. Pequeños agricultores: 45/100 = 0,45
B. Pasto para ganado: 25/100 = 0,25
C. Granjero: 20/100 = 0,20
D. Explotación forestal: 10/100 = 0,10
When a plant or animal dies, it stops acquiring carbon-14 from the atmosphere. The amount y (in grams) of carbon-14 in the body of an
organism after t years is y = a(0.5)
t/5730
where a is the initial amount (in grams). What percent of the carbon-14 is released each year? Round
your answer to the nearest hundredth.
his
about
%
Answer:
0.01 %
Step-by-step explanation:
The given model is;
y = a (0.5)^t/5730
Which is;
y = a(2^-1(t/5730)
Then;
y = a (2^-1/5730)^t
y = a(0.999879)^t
Hence;
Given that the general model is;
y(x)= a(1-r)^x
Where r is the rate percent
Since 1-r =0.999879
r = 0.00012096
y = a(1 - 0.00012096)^t
So;
r= 0.00012096* 100 = 0.01 %

What is the volume of a rectangular prism with a height of 1.5 feet and a base area of 4.5 square feet use the formula V=Bh
Step-by-step explanation:
you can use that same formula to answer that same question
The volume of the rectangular prism is [tex]6.75ft^{3}[/tex]
Diagram of a rectangular prism is shown in the attachment below.
Given that:
the height (h) = 1.5 ft
base area (B) = 4.5 sq ft
Volume of rectangular prism (V) [tex]= Bh[/tex]
Plug in the known values into the formula:
[tex]V = 4.5 \times 1.5\\V = 6.75 ft^{3}[/tex]

Q7.
There are 15 children at a birthday party.
The mean age of the 15 children is 7 years.
9 of the 15 children are boys.
The mean age of the boys is 5 years.
Work out the mean age of the girls.
Answer:
10
Step-by-step explanation:
Let c = sum of ages of all children.
mean age of all children = c/15 = 7
c = 15 * 7 = 105
The sum of the ages of all children is 105.
Let b = sum of ages of the 9 boys.
mean age of boys = b/9 = 5
b = 9 * 5 = 45
The sum of the ages of the boys is 45.
The sum of the ages of the girls is c - b.
c - b = 105 - 45 = 60
The number of girls is 15 - 9 = 6
mean age of girls = (sum of ages of the girls)/(number of girls) =
= 60/6 = 10
The area of a square is 50 square meters. Find the length of a side. LABEL answer!!
Answer:
12.5
Step-by-step explanation:
50÷4=12.5

Step-by-step explanation:
Let the length of a side of a square
= a metre
a² = 50 m²
[tex] \sf{a = \sqrt{50m {}^{2} }}[/tex]
[tex] \sf{ = \sqrt{2 \times 5 \times 5m {}^{2} }}[/tex]

At the beginning of every year, Molly deposits $200 in a savings account that offers an interest rate of 20%, compounded annually. The total
amount that Molly will have in her account at the end of 3 years is $
Answer:
$345.60
Step-by-step explanation:
From the above question,
P = Principal = $200
R = Interest rate = 20%
T = Time in years = 3 years
n = Number of times interest is compounded = Annually = 1
First, convert R as a percent to r as a decimal
r = R/100
r = 20/100
r = 0.2 rate per year,
Then solve the equation for A
The formula =
A = P(1 + r/n)^nt
A = 200.00(1 + 0.2/1)^(1×3)
A = 200.00(1 + 0.2)^(3)
A = $345.60
Therefore, the total amount that Molly will have in her account at the end of 3 years is $345.60
