The dimensions on the scale drawing would be 1 inch by 0.8 inches.
The scale is 1 in: 10 ft; since the actual width of the deck is 10 ft, then it will be 1 inch on the scale. To find the width:
1/10 = x/8
Cross multiply:
1*8 = 10*x
8 = 10x
Divide both sides by 10:
8/10 = 10x/10
0.8 = x
The width on the scale drawing will be 0.8 inches.
Segment WT and DG are congruent which means that the shape and size, but we are allowed to flip, slide or turn. In this example the shapes are congruent (you only need to flip one over and move it a little). Angles are congruent when they are the same size (in degrees or radians). Sides are congruent when they are the same length.
Answer:
64
Step-by-step explanation:
<u>ASSUMING WE STARTED WITH ONE BACTERIA</u>
there are 3 20 minute marks in an hour.
3 x 2 = 6
So are going to do the following
1 x 2 = 2
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
...
So in two hours a bacteria that increases two times every twenty minutes would multiply into sixtyfour bacteria in 2 hours.
Options :
a) np ≥ 10
b) n(1-p ) ≥ 10
c) n ≥ 30
d) The data is a random sample from the population of interest.
e) The sample is less than 10% of the population.
Answer:
d) The data is a random sample from the population of interest.
Step-by-step explanation:
To construct a confidence interval, certain conditions has to be met before the validity of the confidence interval could be established, this include a sufficiently large sample, (n > 30)
n (1- p) ≥ 10 = 132(1 - 104/132) = 132 * 0.2121 = 28 (condition is met).
The condition which the data fail to meet is the randomization condition, whereby the method of selection isn't completely random with some participants having a much more chances of being selected ahead of others. A better random sampling procedure should be is d in the population to draw out the required sample.
