Answer:
135.39
Step-by-step explanation:
The solid consist of 4 triangles and a 5 rectangles.
Formula to calculate area of triangle is
1/2 (height) (base)
Formula to calculate area of rectangle is
length x width
so
Total surface area of the composite solid is
2( 4(4) + 6(4) + 1/2(√13)(4) + 1/2(2√2)(6) ) + 6(4)
111.39 + 24
135.39
Answer: A.) Critical values: r= ± 0.514, no significant linear correlation
Step-by-step explanation:
r = 0.105
n = 15
The level of significance for a two-tailed test is 0.05
The degrees of freedom = n - 2 = 15 - 2 = 13
Using the pearson product moment correlation Coefficient table ; The critical value for the correlation Coefficient is ±0.513977
When the correlation coefficient (for a sample of 15 drawn from the same population) is less than ±0.514 (critical value), that means no significant linear correlation exists.
3/6 6/12 2/4 is a few of them
Answer:
<h2>192 inches ²</h2>
Step-by-step explanation:
P= (l+w)
56 = 2(l+8)
56=2l+8
56-8= 2l
48=2l
Length=24
Area = ?
A = l×w
A=24×8
Area= 192inches²
A census is where you poll everybody; a sample is where you choose a group of people to poll. Taking a census is inefficient because you can get almost completely accurate information from a large sample, but a sample would take significantly less time than a census since you wouldn't have to poll absolutely everybody in a population.
