Answer:
confidence interval using a two sample t test between percents
Step-by-step explanation:
confidence interval using a two sample t test between percents This can be used to compare percentages drawn from two independent samples in this case employees. It is used to compare two sub groups from a single sample example the population on the planet
Answer:
∡ ONQ and ∡ PQN
Step-by-step explanation:
Alternate interior angles are formed by a transversal intersecting two parallel lines . They are located between the two parallel lines but on opposite sides of the transversal, creating two pairs (four total angles) of alternate interior angles. Alternate interior angles are congruent, meaning they have equal measure.So last one is the answerer
Answer:
Length of rectangle: 2n - (1/3) + 9/(3n)
Width of rectangle = 3n
Rectangle area = A = 6 n^2 - n + 9
Step-by-step explanation:
Rectangle area = A = 6 n^2 - n + 9
test what the roots are: b^2 - 4ac = (-1)^2 - 4*6*9 < 0 no real roots
-215 < 0 discriminant
(6 n^2 - n + 9) / (3n) =
2n - (1/3) + 9/(3n)
If the area is divided by 3n, the quotient is 2n - (1/3) and the remainder is 9
Answer:
2.5
Step-by-step explanation:
From the diagram, figure B was enlarged to obtain figure A.
The two figures are therefore similar.
The corresponding sides are in the same proportion. That constant value of the proportion is called scale factor.
It is given by:
Figure B is the image of A
Therefore the scale factor is 2.5
Step 1
Find the area of one equilateral triangle
Applying the law of sines
in this problem
a=b=7 cm
C=60 degrees
so
cm²
Step 2
To calculate the area of the hexagon multiply the area of one equilateral triangle by 
![Area Hexagon=6*[49*\frac{\sqrt{3}}{4}] \\ Area Hexagon=73.5*\sqrt{3}](https://tex.z-dn.net/?f=%20Area%20Hexagon%3D6%2A%5B49%2A%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B4%7D%5D%20%20%5C%5C%20Area%20Hexagon%3D73.5%2A%5Csqrt%7B3%7D%20%20)
cm²
therefore
the answer is the option
73.5 sqrt 3cm²
