Answer:
4
Step-by-step explanation:
This is an isosceles and right triangle at the same time
In fact, this triangle is called 45-45-90 special right triangle and the side lengths for this special triangle is as follows:
The sides that see the angle with measure 45 is represented with x
and
The side that sees the angle with measure 90 is represented with x
one of the sides that has angle measure 45 is given as 4
to find the length of BC we we need to multiply 4
with
4
*
= 4
Answer:
34 and 38
Step-by-step explanation:
A fraction can compare the small parts of a whole, while it could also identify a division problem
Step 1: Simplify 0.02 x 0.789 to 0.01578
0.01578 ÷ 3.0999
Step 2: Simplify 0.01578 ÷ 3.0999 to 0.0051
0.0051
Done! :) Decimal Form Would Be 0.0051
Answer:
The margin of error increases as the level of confidence increases because the larger the expected proportion of intervals that will contain the parameter, the larger the margin error.
Step-by-step explanation:
Margin of Error is a statistical measure of random sampling error insurvey results.
Level of confidence reflects percentage range around sample mean, that can be expected to contain population actual parameter.
High level of confidence means larger range band of confidence interval, supposed to contain the population parameter. This further implies high expected variation between sample statistic & actual parameter i.e Margin Error increases.
