You will find the area the square and then find out what 4/5 of that area is.
A = bh
6 cm x 6 cm
A = 36 square cm
4/5 of 36 square cm
4/5 x 36
28 4/5 square cm
The area of the rhombus is 28 4/5 square cm. Use this to solve for the height of the rhombus.
A = bh
<u>28 4/5</u> = <u>6 x h</u>
6 6
h = 4 4/5 cm
The height of the rhombus is 4 4/5 cm.
Answer:
-1
Step-by-step explanation:
If i = √-1, then i^2 = -1.
Using the normal distribution, it is found that 1851 people would have an IQ less than 115.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The proportion of IQ scores less than 115 is the <u>p-value of Z when X = 115</u>, hence:
Z = 1
Z = 1 has a p-value of 0.8413.
Out of 2200 people:
0.8413 x 2200 = 1851.
