Answer:
y=2x-1
Step-by-step explanation:
The slope intercept form has a general equation which is expressed as:
y = mx+b
where m is the slope and b is the y-intercept.
The three equations with <span> a y-intercept of –5 would be as follows:
y = 8x - 5
y = 3x - 5
y = -7x -5</span>
Answer:
12
Because:
30 is to 25 as x is to 10.
As an equation: 30/25 = x/10
Do this equation by: look at image
Given the information, we shall proceed as follows:
The given problem is a binomial problem.
n=10 and p=0.48
thus, the probability that the number who consider themselves baseball fans is:
a] exactly five
P(x=5)=10C5(0.48)^5(0.52)^5=0.244
b] at least 6
P(x>=6)=1-P(x<8)
=P(6)+P(7)+P(8)+P(9)+P(10)
=10C6(0.48)^6(0.52)^4+10C7(0.48)^7(0.52)^3+10C8(0.48)^8(0.52)^2+10C9(0.48)^9(0.52)^1+10C10(0.48)^10
=0.1878+0.0991+0.0343+0.0070+0.0007
=0.3289
The answer: 0.3289
c] Less than 6
P(x<6)=1-P(x>=6)
=1-0.3289
=0.6711
Use quadratic formula since we can't factor
for 0=ax²+bx+c
so, for
0=1x²-6x-4
a=1
b=-6
c=-4
the solutions are x=3+√13 and x=3-√13
or aprox
x≈6.61 and x≈-0.61
