Answer:
The answer should be 55
Step-by-step explanation:
All triangles must = 180
70+55+55 = 180
Answer: a) 1082, b) wider.
Step-by-step explanation:
Since we have given that
Margin of error = 0.1 millimeter = E
Standard deviation = 2 mm = σ
Critical value would be
a) Sample size would be
b) Sample size, n = 100
So, the margin of error would be
Since the margin of error in b part is more than a part, as we know that the higher the margin of error, the wider the confidence interval.
So, it would have wider confidence interval.
Hence, a) 1082, b) wider.
Answer:
<h3>50m</h3>
Step-by-step explanation:
Given the dimension
Length of the rectangle = 8cm
Width = 5cm
Note that when the scale was 1:7, syla multiplied the width by a factor of 7 i.e 5*7 = 35m
If syla changes the the scale to 1 cm : 10 m for the rectangle, then the width of the shorter side will be multiplied by a factor of 10 due to the change in scale i.e;
5 * 10 = 50m
Hence the width of the new stage will be 50 m
Plug in 4 for r and 1 for s
r+s^2
4+1^2
Evaluate exponents first (order of operations)
4+1
Add
5
Final answer: 5
<h3>
Answer: Obtuse</h3>
This is because the lower left angle is larger than 90 degrees. This is assuming the triangle is drawn to scale (i.e. drawn accurately).
Any time there's an angle larger than 90, the triangle will be obtuse. If there's one angle exactly 90, then it's a right triangle. Otherwise, the triangle is acute (when all angles are smaller than 90).
