Mathematics
1 answer:

Answer:

A. 70°

Step-by-step explanation:

There are two ways to solve this problem:

(1) The sum of all the angles of a quadrilateral equals 360°.

The equation for this problem would be:

110° + 110° + 70° + m∠A = 360°

Simplify:

290° + m∠A = 360°

m∠A = 70°

(2) Trapezoid ABCD is an isosceles trapezoid, because m∠B and m∠C, opposite angles of the same base of the trapezoid, are congruent.

Therefore m∠A and m∠D must also be congruent.

m∠A = m∠D = 70°

Total = 16 marbles
R = 4
B = 7
G = 5

a)
P(R) = 4/17
with replacing it P(B) =  7/17
so 
P(R, then B) = 4/17 x 7/17 = 28/289

b)
P(R) = 4/17
no replacing, P(B) = 7/16
so 
P(R, then B) = 4/17 x 6/17 = 24/289

c)
The answers to parts a and b are not the same. 
Part a (28/289)  with replacing, the probability to select a red then blue is higher then part b (24/289)

predict the attendance for minor league baseball in the year 2005. a. 5,208,000 b. 4,495,000 c. 44,950,000 d. 52,080,000
solong [7]

Answer:

c. 44,950,000

Step-by-step explanation:

The following table is missing:

Year   Attendance (millions)  

1985   18.4  

1990   25.2  

1995   33.1  

2000  37.6  

Using a calculator, the line of best fit is obtained. Equation:

y = 1.31x - 2581.6

where y is attendance (in millions)  and <em>x</em> is the year. Replacing with x = 2005 into the equation, we get:

y = 1.31(2005) - 2581.6

y = 44.95 millions or 44,950,000
