b bell-shaped
c skewed right
d uniform
The skewness of a graph is a function of how much the random variable deviates from the normal distribution.
The shape of the distribution is (c) skewed right
From the attached image, we can see that:
The points are concentrated on the left-hand side of the graph, and the points decreases as it approaches the right-hand side.
The above highlight means that:
The shape of the distribution is skewed right.
Hence, the correct option is (c)

Answer:
The value of cosA = (√3)/2 and tanA = 1/√3 or (√3)/3.
Step-by-step explanation:
Firstly,youhavetofindthevalueofadjacentusingPythogoras'Theorem,a²=b²+c²:
Let a = 2, b = 1
2² = 1² + c²
c² = 2² - 1²
= 4 - 1
= 3
c = √3
NowwehavefoundtheadjacentsowecanfindcosAandtanAusingTrigonometricfunction,cosθ=adj./hypo.andtanθ=oppo./adj.:
adj. = √3
oppo. = 1
hypo. 2
cosA = (√3)/2
tanA = 1/√3 OR (√3)/3
(Enter answer in decimal form.)
