[ Explanation ]
--------------------------------
1 Triangle
1 Triangle
1 Square
Area Of Triangle - · Height
Area Of Square - Base · Height
Triangle:
Height - 12
Base - 9
4.5 · 12 = 54
54 + 54 = 108
2 Triangles = 108
--------------------
Square:
Base - 9
Height - 9
9 * 9 = 81
--------------------
81 + 108 = 189
Answer:
c
Step-by-step explanation:
you should divide the distance on time
so
33/6=5.5
26/4=6.5
60/8=7.5
17/2=8.5
you can see answer in this order in c
Answer:
33 plants
Step-by-step explanation:
6 x 550 = 3300
3300/100 = 33
Using the normal distribution, there is a 0.2148 = 21.48% probability that the sum of the 40 values is less than 7,100.
<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.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation .
For this problem, these parameters are given as follows:
A sum of 7100 is equivalent to a sample mean of 7100/40 = 177.5, which means that the probability is the <u>p-value of Z when X = 177.5</u>, hence:
By the Central Limit Theorem:
Z = -0.79
Z = -0.79 has a p-value of 0.2148.
There is a 0.2148 = 21.48% probability that the sum of the 40 values is less than 7,100.
