Answer:
<em>The perimeter of the green cross is 32 cm</em>
Step-by-step explanation:
<u>Perimeter</u>
It's the sum of all the external side lengths of a given shape.
The green cross formed by two rectangles is shown in the figure below.
We have outlined the dimensions of the external sides of the resulting cross.
Note there are four corners of 2 cm by 2 cm and four sides of 4 cm each.
The total perimeter is:
8 * 2 cm + 4 * 4 cm = 16 cm + 16 cm = 32 cm
The perimeter of the green cross is 32 cm

Answer:
Option 2) 2x3 – 6x2 – 14x + 24 square centimeters
Step-by-step explanation:
We know the Parallelogram Area is given by
Eqn. (1)
where
: is the base
: is the height
We are also given that the base is
and the height is
So we can plug these two expressions in Eqn. (1), simplify and find our Area equation as follow:
Which matches Option 2. from the available ones.
The value that is 2 standard deviations from the mean is; 130
<h3>What is Empirical Rule?</h3>
For this question, we will use Z-score and as such whether the value is below or above mean (shown by positive or negative sign) and by how much (times the standard deviation).
Thus;
Calculated value = μ + zσ
where;
μ is mean
σ is standard deviation
Hence, the value that would be +2 standard deviations from the mean is;
Calculated value = 100 + 2(15)
Calculated value = 130

Answer:
30 days.
Step-by-step explanation:
22 1/2 = 45/2 since 22*2+1 = 45, then divide that by 3/4 which, in reality, means multiply by 4/3. I then cross-multiplied by finding the GCF of the diagonal pairs. I hope this helped! Please mark Brainliest if it did.
