6 0

at most is either that number or less

so x<=72 would be the inequality

Answer:

because either x-6=0 or x+1=0

x-6=0

x=0+6

x=6 OR,

x+1=0

x=0-1

x=-1

What does it mean if a statistic is resistant? choose the correct answer below.

matrenka [14]

When we say a statistic is resistant, we mean the extreme values do not affect the statistic to a large extent or to an extent which makes a major difference. Mean and median are example of such statistics. By changing the extreme values we do not see a substantial difference in the value of mean and median for the data set.

Consider a sample: 1,2,3,4,4,5,6,7,8
The median for this data set is 4.
If we change the extreme values to get this sample: -5,2,3,4,4,5,6,7,100
The median will still be the same i.e. 4. This is what is meant by a resistant statistic.

So option a is the correct ans.

In the circle, m arc BC = 72°. The diagram is not drawn to scale. <br><br>What is m angle BCP

QveST [7]

Answer:

Measure of ∠BCP is 36°

Step-by-step explanation:

Given the circle in which measure of arc BC is 72°

we have to find the measure of angle BCP.

m∠BOC=∠2=72°

By theorem angle subtended at the centre is twice the angle formed at the circumference of circle.

∴ ∠2=2∠1 ⇒ 72=2∠1
