Answer:
Report the length as x inches to the nearest quarter of an inch.
See the example below
Step-by-step explanation:
Report the length as x inches to the nearest quarter of an inch.
E.g : If the actual length is 2.4 inches then the reported length would be 2.5 in
Similarly if the actual length is 2.3 inches then the reported length would be 2.25 in
Option (c) is correct according to me I think it’s helpful
Answer: 68
Step-by-step explanation:
Formula for sample size when prior estimate of population proportion (p) is available: 
, where z*= critical-value.
E= Margin of error.
Let p be the population proportion of trees are infected with the citrus red mite.
As per given , we have
E= ± 0.08
The critical z-value corresponding to 90% confidence level = z*=1.645
Substitute all the values in the above formula , we get
Required sample size :
[Rounded to next integer.]
Thus, the minimum sample size should be taken =68
Answer:
Step-by-step explanation:
1 cm=10 km
8 cm=10×8=80 km
a) To find the missing side length on triangle A, we can use the Pythagorean theorem.
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 5 cm
5 and 12 = 5 and 12
b) The two triangles are congruent because they have two side lengths in common. If at least two side lengths are the same on two triangles, then they are congruent. In addition, these triangles have one angle in common as well.
Hope this helps!! :)
