Answer:
The tree is 28 feet tall.
Step-by-step explanation:
It is given that:
Height of flag pole = 8 feet
Shadow of flag pole = 6 feet
Ratio of height to shadow = 8 : 6
Shadow of nearby tree = 21 feet
Height of nearby tree = x
Ratio of height to shadow = x : 21
8 : 6 :: x : 21
Product of means = Product of extremes
6x = 8*21
6x = 168
Dividing both sides by 6
Therefore,
The tree is 28 feet tall.
Answer:
range is 515, mode:All values are equal, Median is 243 and the mean is 311.18
mean:to find the mean you need to add up all you numbers so all of these add up to be 3423 and then you divide by the amount of numbers which it 11 so 11 / 3423 = 311.18 so the answer is the mean is 311.18
median: to find it you need to put all the numbers smallest to biggest so it would be in the order 155, 175, 190, 210, 213, 243, 340, 380, 390, 457, 670 and then you pick the one in the middle and that would be 243
mode:All values appeared just once so there is not one
range: to find the range to need to find the differences in the smallest to the biggest number so smallest one is (155) biggers (670) so 155 - 670 = 515 so the range is 515

Answer:
C. The data is skewed to the left and shows that she never scored fewer than 2 points or more than 12 points in a game.
Step-by-step explanation:
In the given image that is representing the number of points that Shira scored, each basketball game so far this season we can observe that the data is skewed to the left.
Lets consider the definition of skewness of a data set:
A left-skewed distribution has a long left tail. Left-skewed distributions are also known as negatively-skewed distributions. That’s because there is a long tail in the negative direction on the number line. So in this case peak remains on the right side.
A right-skewed distribution has a long right tail. Right-skewed distributions are also called positive-skew distributions because there is a long tail in the positive direction on the number line. So in this case peak remains on the left side.
In our case it can be see that the data has peak on to the right side and hence it is left skewed. Also it can be seen from the dot plot that Shira has never scored fewer than 2 points and the maximum she has scored in a game is 12 points.
Therefore, the data is skewed to the left and shows that she never scored fewer than 2 points or more than 12 points in a game
