To model 32%, you would just color in 32 out of 100 blocks. It represents the ratio because out of 100 blocks, 32 are shaded.
Answer:
13 units.
Step-by-step explanation:
units
x = 13 units (answer rounded up to nearest tenth)
Answer:
b) the mean will be off center in the boxplot and above the median
Step-by-step explanation:
First, we must inform that the median is not affected by outlier. Thus, there is possibility that a (some) student(s) score very high than others. This account for the reason why the mean value is higher than the median.
Since the mean is higher than the median, the score is skewed to the left! That is, majority of the students score low. Hence, we can say that the score is not exactly normal distributed.
NB:
Statistically the mean value given by the teacher is not significantly different from what the students obtained from the sample taken. This implies that, the sample is unbiased of the population mean as given by the teacher.
X = 3
Explanation:
In a rhombus, the diagonals are perpendicular, creating four congruent right triangles.
Because the value of all three angles within any given triangle will add up to 180°, we can easily simplify the equation.
First, we’ll need to add our given angles. Which are 32° (as can be seen on the graph) and 90° (because any pair of perpendicular lines create four right angles and this triangle includes one of them).
32° + 90° = 122°
Next, we’ll subtract 122 from 180 to find the remaining angle measure
180 - 122 = 58
Then, we’ll subtract 31 with the subtraction property of equality
58 - 31 = 27
Right now, our equation looks like:
27 = 9x
In order to simplify this equation further, we must use the division property of equality to get x on its own.
27/9 = 9x/9
3 = x
