It would be impossible to have ten girls born in succession, without any boys being born there. If a girl is born, then the next birth should be a boy. One would expect an approximately equal number of boys and girls born over an extended period of time. A correct interpretation for the above statement would be: Over the next 100 births, there will be exactly an equal number of boys and girls born at that hospital.

Apply 5. You can calculate the surface area, \( S A \), of a sphere using the formula \( S A=4 \times \pi \times r \times r \), where \( r \) is the radius. a) Rewrite the formula using powers and no multiplication signs. b) Identify the coefficient, variable, and exponent in your formula. c) Use your formula to determine the surface area of a sphere with radius 10 cm .

CCSS Multiple Representations In this problem, explore rates. Abigail left Charlotte, North Carolina, 30 minutes before Juan did, to travel to Greenville, South Carolina. Two and a half hours after Abigail left, she had traveled 155 miles, and Juan had traveled 144 miles. a. Table Make a function table to show how far each person has traveled after Abigail has traveled 1, 2,3, and 4 hours. b. Graph Make a graph of the data. Do the two lines intersect? If so, what does this intersection point represent?

7. A grain silo contains 1,330 tons of corn. The corn will be divided equa among 42 trucks. To find the amount of corn in each truck, Eliot tries solve \( 1,330 \div 42 \). He estimates that the first digit of the whole-numb quotient will be 2 tens. How should he adjust the first digit? \( \begin{array}{ll}\text { (A) adjust it up to } 3 \text { tens } & \text { (C) adjust it up to } 2 \text { hundreds } \\ \text { (B) adjust it down to } 1 \text { ten } & \text { (D) adjust it down to } 2 \text { ones }\end{array} \) Describe the estimated digit in the whole-number quotient as too high
