Answer:
blank = 0.985
Step-by-step explanation:
Let's say blank = x.
1 - x = 0.015
x = 1 - 0.015
x = 0.985
Therefore, blank = 0.985.
Answer:

Now we can estimate the population variance with the sample variance given by:

And replacing we got:

And the estimator for the population deviation
is given by :

Step-by-step explanation:
For this case we have the following data given:
1.83,1.85,1.79,1.73,1.69,1.74,1.76,1.70
First we need to calculate the mean with the following formula:

And replacing we got:

Now we can estimate the population variance with the sample variance given by:

And replacing we got:

And the estimator for the population deviation
is given by :

Answer:
80 km/hr
Step-by-step explanation:
This is asking for speed.
Speed=Distance/Time
Speed=720/9
Speed=80 km/hr
Answer:
it aproximatley 7.937 rounded to the nearest tenth its 7.9
Step-by-step explanation:
Answer:
1=163 degrees
2=×=10 degrees
3=×=3
Step-by-step explanation:
54x+1+9x-10=180 we are using this expression because alternate angles add up to 180 degrees
54x+9x+1-10=180
63x-9=180
63×=180+9
63×=189
63×÷63×=189÷63×
X=3
Angle in bold print is (54x+1)
54×3=162
162+1=163 degrees
No.2 Find x
7x+35+x+65 =180
7x+x+35×65=180
8x+100=180
8x=180-100
8x=80
8x÷8x=80÷8
X=10 degrees
No.3 Find x
54x+1+9x-10=180
54x+9x+1-10=180
63x-9=180
63x=180+9
63x=189
63x÷63x=189÷63
X=3
