Answer:
<h2>b=-4</h2>
Step-by-step explanation:
<h3>-1/2b+3=5</h3><h3>-1/2=5-3</h3><h3> -1/2b=2×-2</h3><h2> b=-4</h2>
The probability that a randomly chosen person from this group has type B is <u>3/25</u>
The probability that a randomly chosen person from this group has type AB is <u>1/25</u>
The probability that a randomly chosen person from this group has type B or type AB blood is <u>4/25</u>
They square root of 0.64 is 0.8
The perimeter of the rectangle is equal to the doubled sum of the sides, and the area is equal to the product of the sides. So we have the following equation
3 x 2x = 2(3 + 2x)
6x = 6 + 4x
2x = 6
x = 3
