The bird is made of 79 squares each square is 1u^2(u=unit, either cm or inch)

the area of the bird is 79u^2

the perimeter is 64u^2 you count all edges

51/79 squares are green, 51u^2

26/79 squares are blue, 26u^2

Viefleur [7K]

Answer:

3.188

Step-by-step explanation:

Given that :

Sample data: 26.5, 28, 30.2, 29.6, 32.3, 24.7

Sample standard deviation (s) = 2.728

Mean (mu) = 25

Tstatistic formula :

(x - mu) / (s/sqrt(n))

n = sample size = 6 ; s = 2.728 ; mu = 25

Sample mean (x) = (26.5 + 28 + 30.2 + 29.6 + 32.3 + 24.7) / 6

Sample mean (x) = 171.3 / 6 = 28.55

Tstatistic = (28.55 - 25) / (2.728 / sqrt(6))

Tstatistic = 3.55 / 1.1137013

Tstatistic = 3.1875692

Jagan and Mithun calculated the value of 12 - 6 + 4.The steps are given alongside.

san4es73 [151]

Answer:

Step-by-step explanation:

Explanation:

$12 - 6 + 4$

In order to solve this, we must use PEMDAS.

This is because there are more than one operations involved.

PEMDAS is the order in which you must solve the operations.

PEMDAS STANDS FOR:

Parenthesis
Exponential Notation (exponents)
Multiplication/division (do whichever comes first)
Addition/subtraction (do whichever comes first)

Solve.

Now, using PEMDAS, I will solve.

There are no parenthesis.

There are no exponents.

There is no multiplication nor division.

There is addition and subtraction.

$12-6+4$

$12-6=6$

$6+4$

Lastly, there is addition.

$6+4=10$

Conclude:

I, therefore, believe $12-6+4=10.$

You did not clarify the answers of Jagan nor Mithun.

So, whichever person got the answer of 10 is correct.
