You may recall that you can't take the square root of a negative number (if you want a real number). So, the area under the square root, also known as the radicand, must be zero or positive. This is how we restrict the domain.
We write the inequality
.
B
Just know, y=Mx + B is the formula for slope and the M represents slope always
I think that it is -762/(762-721)% or -18.58...% so -18.6%
Answer:
question 1 , area= 42.02 sq meter, circumference=22.98 meter
question 2, area=481.609sq meter, lenght of BC=263.3472 meter
for convience i converted yards to meter.
Step-by-step explanation:
in first question to find area of circle by multiplying value of pi (3.14) and square of radius of circle and to find circumference just multiply 2 with value of pi(3.14) and radius of circle.
in the second question to find area of sector use formula 1/2 r^2 x72 and to find lenght of arc bc use formula length= radius x 72
Answer:
A statistics class with 36 students is arranged so that there are 6 rows with 6 students in each row, and the rows are numbered from 1 through 6. A die is rolled and a sample consists of all students in the row corresponding to the outcome of the die. This is not a simple random sample. It is a random sample only.
For the same class described in part (a), the 36 student names are written on 36 individual index cards. The cards are shuffled and six names are drawn from the top. This is a simple random sample. It is also a random sample.
For the same class described in part (a), the six youngest students are selected. This is not a simple random sample. It is also not a random sample.
