Answer:  9x - 12 y =32

Step-by-step explanation:

Since, the equation of a line passes through one point (x_1,y_1) and having the slope m is,

y-y_1 = m(x-x_1)

Here, x_1 = 4, y_1 = 1/3 and m= 3/4

Therefore, equation of the line,

y-1/3 = 3/4(x-4)

⇒ 3y -1 = 9/4 (x-4)

⇒ 12 y - 4 = 9x - 36

⇒ 9x - 12y = - 4 + 36

⇒ 9x +12y = 32

Which is required equation of the line.

Y = mx + b
m = slope of the line
b= y-intercept

Since you are given the point (4,1/3), the y-value is 1/3.
So plug in the numbers and solve for b:
(1/3)= (3/4)*(4) + b

After you solve the equation for b, you should get -2 2/3 or -8/3

No rewrite the equation with the y-intercept, b.

y = (3/4 x) - (8/3)

Andrews [41]

Answer:

There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes (P-value=0.009).

Step-by-step explanation:

We have to perform an hypothesis test on the mean.

The null and alternative hypothesis are:

H_0: \mu=10\\\\H_1: \mu \neq 10

The significance level is \alpha=0.05.

The test statistic t can be calculated as:

t=\frac{M-\mu}{s/\sqrt{N} } =\frac{11.2-10}{3.1/\sqrt{50} }=2.737

The degrees of freedom are:

df=N-1=50-1=49

The P-value (two-tailed test) for t=2.737 and df=49 is P=0.00862.

This P-value (0.009) is smaller than the significance level, so the effect is significant. The null hypothesis is rejected.

There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes.
