Y = 3x + 13
You can get this by using the same slope and then plugging into the equation to find the intercept. <span />
Answer:
0.9544
Step-by-step explanation:
We are given that mean=18 and standard deviation=1 and we have to find P(16<X<20).
P(16<X<20)=P(z1<Z<z2)
z1=(x1-mean)/standard deviation
z1=(16-18)/1=-2
z2=(x2-mean)/standard deviation
z2=(20-18)/1=2
P(16<X<20)=P(z1<Z<z2)=P(-2<Z<2)
P(16<X<20)=P(-2<Z<0)+P(0<Z<2)
P(16<X<20)=0.4772+0.4772=0.9544
The probability that the height of a tree is between 16 and 20 feet is 95.44%
Website 1 : y = 1.50x + 30
website 2 : y = 2x + 0...or just y = 2x
=======================
y = 4x - 4
y = -4x + 4
4x - 4 = -4x + 4
4x + 4x = 4 + 4
8x = 8
x = 1
y = 4x - 4
y = 4(1) - 4
y = 4 - 4
y = 0
so this is a consistent system because it has one solution (1,0)
Answer:
7, 27, 28, 63
Step-by-step explanation:
The possible values of xy are
3 × 4 = 12
3 × 9 = 27
7 × 4 = 28
7 × 9 = 63
