Answer:
N = 102.306 (There's your answer)
Answer:
1. A. contain a right angle
1. B. opposite sides are parallel
2. (c) 2 pairs of parallel sides
3. (b) 2 sides of equal length
Step-by-step explanation:
Here you are asked to find patterns and to make use of the definitions of different geometric figures.
<h3>1.</h3>
The figures in Circle A do not all have the same number of sides, or sides of the same length. However, they do all have at least one right angle.
The figures in Circle B are rectangles and parallelograms. The attributes listed in question 2 can be used here. They all have two pairs of parallel sides.
<h3>2.</h3>
As we observed in question 1, rectangles and parallelograms share the feature of 2 pairs of parallel sides.
A kite may have 2 pairs of equal-length sides. While a square and a rhombus have 4 sides of equal length, that description is not true of rectangles and parallelograms in general.
Angles in a rectangle are all 90°, while those in a parallelogram may not be. The offered descriptions of angles do not apply to apply to both shapes.
<h3>3.</h3>
An isosceles triangle has two sides equal length and two equal angles. An equilateral triangle is a special case of an isosceles triangle in which all three sides are equal, as are all three angles. The description that applies to both kinds of triangles is 2 sides of equal length.

Answer:
Yes
Step-by-step explanation:
Given,
Population mean Z = 600
Sample mean, µ = 586.50
Size of the sample, n = 10
Standard deviation, σ = 26.77
The testing hypothesis is,
Null hypothesis = µ<600
Alternative hypothesis = µ≥600
The test statistics is the calculated value of Z,
(Z- µ)/(σ/√n)
= (600-586.50)/(26.77/√10)
= (13.5*3.1623)/26.77
= 42.691/26.77
= 1.5947
And at 5% level of significance, the table value of Z = 1.644
Here, calculated Z<Table value of Z, so we accept the null hypothesis.
So, the null hypothesis is accepted. The mean value of the laptop is less than 600.
