Im going to guess its 5/12. i havent learnt this but check my working. so the chances of getting multiple of 3 on first roll is 2/6 = 1/3. the posibility of getting total of 8 on both rolls is 5/6×1/6 = 5/36. so 5/36÷1/3=5/12? im really not very sure on this
The 3 terms are 1, -1, and -3.
Recursive= Previous - 2.
Explicit= -2n+ 13
To solve the question we proceed as follows:
mean=142
standard deviation=14
a] Find the interval in which 68% of the data lies:
P(x<X)=68%=0.68
the z-score associated with this probability is:
P(z<Z)=0.47
but :
z=(x-mu)/sig
thus;
0.47=(x-142)/14
solving for x we get:
x=148.58
thus 68 percent of the data lie below 148.58
b]<span>what is the probability that a man picked at random from the unit will weigh more than 170 pounds?
</span>x=170
thus
P(x>170) will be:
z=(170-142)/14
z=2
Thus
P(x>170)=1-P(z<2)
=1-0.9772
=0.0228
c] <span>that he will weigh less than 128 pounds?
P(x<128)
z=(128-142)/14
z=(-14/14)=-1
Thus
P(z<-1)=0.1587</span>
Answer:
The fractions you make from the coordinates on the graph is equal. If it is then the graph is proportional

Answer:
Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
The general form of an equation of a circle:
We have the center (-2, 1). Substitute to the equation in the standard form:
Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:
Therefore we have the equation:
Convert to the general form.
