Answer:

y=3x+7

Step-by-step explanation:

y=mx+c

m=3 parallel lines have the same gradient

(-2,1)

(x,y)

y=mx+C

1=3x-2+c

1=-6+c

c=7

y=3x+7

A large jar contains a mixture of white and black beans. In a randomly chosen handful of 120 beans 40 were black. Create a 98% c
dusya [7]

Answer:

23%<x<43%

Step-by-step explanation:

The formula for calculating confidence interval is expressed;

Confidence Interval = p ± z√p(1-p)/n

n is the sample size

z is the z score at 98% confidence interval

n is the sample size = 120

z =  2.33

If in a randomly chosen handful of 120 beans 40 were black, then;

p = 40/120

p = 4/12

p = 0.33

CI = 0.33± 2.33√0.33(1-0.33)/120

CI = 0.33± [2.33√0.33(0.67)/120]

CI =  0.33± [2.33√0.2211/120]

CI = 0.33± [2.33(0.04292)]

CI = 0.33±0.100014

CI = (0.33-0.100014, 0.33+0.100014)

CI = (0.229, 0.430014)

CI = (22.9, 43.0014)

Hence 98% confidence interval for the proportion of black beans in the jar is 23%<x<43%.

What is the slope of the line whose equation is 12 = 4x – 6y?
timama [110]
12=4x-6y \\ -4x  -4x \\ 12-4x=-6y \\ /-6   /-6 \\ -2+ \frac{2}{3}x=y
therefore the slope of the line is \frac{2}{3}
