2/10, i believe this is pretty self explanatory
Answer:
39.19 yards^2
25.15 yards
Step-by-step explanation:
To determine the squares square yards of carpet needed, we have to determine the area of the room
The room is shaped like a rectangle
area of a rectangle = length x breadth
5.7 x 6 7/8
To multiply, convert 6 7/8 to a decimal
to do this, divide 7 by 8. Add the value gotten to 6
5.7 x 6.875 =39.19 yards^2
To determine the yards needed for the border, calculate the perimeter of the room
Perimeter = 2 x (length + breadth)
2 x(5.7 + 6.875) = 25.15 yards
Answer: c. 3.01
Step-by-step explanation:
The test statistic for difference between two population mean (when population standard deviation is known) is given by :
, where 
= Size of first sample
= Size of second sample
= Difference between two sample mean.
= standard deviation for population 1.
= standard deviation for population 2.
As per given , we have
Substitute these values in formula , we get
Hence, the value of the test statistic is <u>3.01</u>.
Hence, the correct option is c. 3.01 .
27%
65/245 = 0.2653
Multiply 0.2653 by 100 to get the percentage = 26.53%
Rounding to the nearest whole percent = 27%
