Answer:
see below
Step-by-step explanation:
The slope-intercept form of a line is y = mx + b where m and b are the slope and y-intercept respectively. From the graph we see that b = 11 (because it is halfway between 10 and 12) and m = 3 (see 2 marked points on the graph). Therefore our answer is y = 3x + 11.
Answer:
The probability of having exactly two girls is 3/8 or 0.375
Step-by-step explanation:
Since the likelihood is equal, the probability of having a boy = probability of having a girl = 1/2
In written form;
P(g) = P(b) = 1/2
We use the Bernoulli approximation to know the probability of having two girls.
Mathematically, that would be;
3C2 P(g)^2 P(b)^1
Inserting the values , we have;
3 * (1/2)^2 * (1/2)
= 3 * (1/2)^3 = 3/8 = 0.375
Try this solution:
Common view of the equation of the circle is (x-a)²+(y-b)²=r², where point (a;b) is centre of the circle, r - radius.
1. using the coordinates of the centre and point (2;13) it is possible to define the radius of the circle: r=√(5²+12²)=13;
the equation is (x+3)²+(y-1)²=13² or (x+3)²+(y-1)²=169;
2. using the coordinates of the centre and the radius: (x-2)²+(y-4)²=6² or (x-2)²+(y-4)²=36.
Answer:
A. he should subtract 1 1\2 instead of adding it
B. he should subtract 1 1\2 instead
C. the answer should be 3 3\22 instead of 6 3\22
Step-by-step explanation:
so to solve for 3 3\22:
4 7\11 - 1 1\2
4 14\22 - 1 11\22
= 3 3\22
