Answer:
The answer to your question is Perimeter = 8.5 cm; Area = 3.75 cm²
Step-by-step explanation:
Data
base = 3 cm
height = 1.25 cm
Formula
Perimeter = 2(base) + 2 (height)
Area = base x height
Process
1.- Calculate the perimeter
Perimeter = 2(3) + 2(1.25)
Perimeter = 6 + 2.5
Perimeter = 8.5 cm
2.- Calculate the area
Area = 3 x 1.25
Area = 3.75 cm²
Substitute y
3(6x+2)-18x=12
18x+12-18x=12
18x-18x=0
0=0
Solution: Infinitely many solutions

Answer:
112
Step-by-step explanation:
Total students = 840
Number of students surveyed = 60
Number of students of the 60 with siblings > 3 = 8
Number of students of the 840 with siblings > 3 = 840/60*8 = 112
you can use the formula for sample means:
[/tex]
where m stands for a value of the sample mean.
We are looking for the value, specifically for its two borderline values: 70 and 80
and their cumulative probabilities, p(z(80)) and p(z(70)). The difference p(z(80))-p(z(70))
will give the probability that m falls in the interval [70,80]
So let's get cracking at it:
These are very large values of z. You may notice that any z-table online won't even bother covering range that high - the probabilities for these values are virtually 0 (in the neg case) 1 (in the pos case).
This means that numerically the probability of the sample mean of 64 samples falling within the range of 1 standard deviation is very close to 1
So the answer choice should be 1.0
