Answer:
0.705
Step-by-step explanation:
Data:
walks=0.65 and is late=0.4;is not late=0.6
cycles=0.35 and is late=0.1;is not late=0.9
The probability of sheila walking and not being late:
0.65 x 0.6=0.39
AND probability of being not late and cycling:
0.35 x 0.9=0.315
therefore,the probability of sheila walking or cycling and still not being late:
0.39+0.315=0.705
Answer:
The table doesn't display a linear relationship because the slope doesn't stay constant throughout the whole table.
Answer:
Its statistically significant, that Mean monthly apartment rent in town east < $ 750
Step-by-step explanation:
Null Hypothesis [H0] : Mean monthly apartment rent in town east = 750
Alternate Hypothesis [H1]: Mean monthly apartment rent in town east < 750
t = (x' - u) / (s / √n)
x' = sample mean = 737
u = population assumed mean = 750
s = standard deviation = 23
n = no. of units in sample
t = (737 - 750) / (23 / √18) = -13 / 5.4212
= -2.39
t tabulated critical value : for one sided 0.05 significance level, at 17 degrees of freedom = -1.740
t calculated value, -2.39 < t tabulated critical value, - 1.740
We reject the null hypothesis, & state that its statistically significant, that Mean monthly apartment rent in town east < 750
Answer:
The answer to your question is below
Step-by-step explanation:
Data
base = 11 km
height 1 = 7 km
height 2 = 10 km
a) Name of the solid = Triangular prism
b) The base is a triangle
c) Volume
Formula
Volume = 1/2 base x height 1 x height 2
-Substitution
Volume = 1/2 (11) x (7) x (10)
-Simplification
Volume = 1/2(770)
-Result
Volume = 385 km³
