Answer:
sqrt. 65
Step-by-step explanation:
assuming that it is a right angle
7^2 + 4^2 = c^2
c=sqrt. 65
Answer:
(1) Parallelogram A parallelogram is a quadrilateral with two
sets of parallel sides. The opposite or facing sides of a
parallelogram are of equal length, and the opposite angles of a
(2) Square
A square is a regular quadrilateral. This means that is has four
equal sides and four equal angles.
(3) Rhombus A rhombus is a quadrilateral whose four sides all have the same
length. Opposite angles of a rhombus have equal measure. The two
diagonals of a rhombus are perpendicular.
(4) Rectangle
A rectangle normally refers to a quadrilateral with four right
angles.
Parallelogram
Step-by-step explanation:
the height of the poster must be multiplied by the ratio which is 1 to 2.5 which is 40 cm.
Answer:
See explanation below
Step-by-step explanation:
Since each time after the person gets off the scale, the reading is 2 lb the person's weight must be near the mean of
148-2, 151-2, 150-2, 152-2; that is to say, near the mean of 146, 149, 148, 150 = (146+149+148+150)/4 = 148.25
We could estimate the uncertainty as <em>the standard error SE
</em>
where
<em>s = standard deviation of the sample
</em>
<em>n = 4 sample size.
</em>
Computing s:
So, the uncertainty is 1.479/2 = 0.736
<em>It is not possible to estimate the bias, since it is the difference between the true weight and the mean, but we do not know the true weight.
</em>
