What is the slope of the line that passes through the points (2, 3)

Komok [63]

Slope is found when you put y2-y1/x2-x1. So your equation would be (-2)-2/6-3.
That answer would be -4/3. Nothing can be simplified further, so that is your answer

A house cleaning service claims that it can clean a four bedroom house in less than 2 hours. A sample of n = 16 houses is taken

Vera_Pavlovna [14]

Answer:

Option B is right

Step-by-step explanation:

$H_0: x bar =2\\H_a: x bar$

(One tailed test at 5% significance level)

n =16 and x bar =1.97

s =0.1

Std error of mean = $\frac{s}{\sqrt{n} } \\=0.025$

Mean diff = $1.97-2 =-0.03$

t statistic =Mean diff/se =-1.2

df =16-1=15

p value =0.124375

(B) do not reject the null because the test statistic (-1.2) is > the critical value (-1.7531).

Work out the perimeter of this semicircle take pie to be 3.142 radius in image attached thanks (:

inna [77]

Answer:

$\boxed{P = 56.55751919 cm}$

Step-by-step explanation:

Perimeter of semicircle = $\frac{2\pi r}{2} + 2r$

Where r = 11 cm

=> P = $\frac{2(3.142)(11)}{2} + 2(11)$

=> P = $34.55 + 22$

=> P = 56.55751919 cm
