Answer:
Concept: Rectangular Figures
- We want the perimeter, we are missing side AB
- We are told AB= CD+EF+GH
- Hence: 2cm+2cm + 2 cm= 6 cm = AB
- Hence: BC= 2+3+2=7 cm
- So we have everything we need: 6+7+2+2+2+3+2+2= 25 units
Answer: 10cm^3 equals density please give briainliest
Step-by-step explanation: formula D=M/V
so D=20/2
D=10cm^3
Answer: 4
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that a simple random sample of 40 ten-gram portions of the food item is obtained and results in a sample mean of x overbarequals2.5 insect fragments per ten-gram portion.
a) By central limit theorem for samples randomly drawn with large sample sizes (atleast 30) the sample mean follows a normal distribution irrespective of the original distribution it belonged to.
b) Mean of X bar = Sample mean = 5
Std error of x bar = s/sqrt n =
c) P( x bar >5.8) = P(Z>)
=0.4930
-x^4 + x^3 - 9x + 3
The ^ are raising it to the powers
