Answer:
Step-by-step explanation:
<u>The gray triangles have</u>
- Base of 20 cm and added height of 60 cm for 2 triangles in each section of AMND and MNCB
<u>The grey area in total is</u>
- 1/2*20*60 + 1/2*20*60 = 20*60 = 1200 cm²
Answer:
a. The sampling distribution of the sample mean will have a smaller standard deviation than the population.
b. The sampling distribution of the sample mean will have a different standard deviation than the population.
c. The shape of the sampling distribution of the sample mean will be skewed right.
Step-by-step explanation:
Answer:
x=-34.6
Step-by-step explanation:
(x)tan12= 22/x(x)
tan12\xtan12=22/tan12
x= -34.6
Answer:
The lateral area = 450 mm²
Step-by-step explanation:
The lateral area of any prism is equal to the areas of the sides faces
∵ The base of the prism is triangle
∴ It has 3 side faces
∵ The lengths of the side faces are 5 , 12 , 13 and their height is 15
∴ The lateral area = (5 × 15) + (12 × 15) + (13 × 15)
= 75 + 180 + 195 = 450 mm²
Answer:
The probability it is greater than or equal to 0.95 and less than or equal to 0.96
Step-by-step explanation:
In order to calculate the probability that weekly demand exceeds 4,044 we would have to calculate the z value as follows:
Z= (X-mean)/standard deviation
Z= (4044 - 3211)/484
Z=1.721
So, looking for standard normal distribution table 1.7 from row, we get values from 0.9554 till 0.9633, for column 0.02 it is 0.9573
Therefore, the probability it is greater than or equal to 0.95 and less than or equal to 0.96
