Answer:
c
Step-by-step explanation:
It has a constant value.
First, let’s start off by removing the two that don’t a a brother or sister. That leaves 10 people who do. The we calculate the access answers. They go in the middle. It’s 6. Then we have one more that has only a sister, put that at the S side. Then we have 3 more left that have only a brother, put them on the B side. Then you have 10 dots on the diagram for the 10 peoples that have a brother and/or a sister.
To conclude:
3 on B
6 in between
1 on S
Answer:
acute angle
Step-by-step explanation:
<h2><em><u>Finding the angle </u></em></h2>
an obtuse angle is an angle which is more than 90° but less than 180°
a right angle is 90°
a straight angle is 180°
an acute angle is less than 90°
is you look at the picture and the definitions you can notice that the angle is less than 90 ° hence its an <u>acute angle </u>
The statements that are true are:
A : Vertical angles are congruent, therefore, another angle must equal 67°
F: Two of the angles formed will have a sum of 180°
What happens when two lines intersect?
When two lines intersect, their vertical angles are always the same and the sum of the two angles on a straight line is 180°

Answer:

Step-by-step explanation:
the probability that x iPads are defective in the sample follows a hypergeometric distribution, so it is calculated as:

Where 
Because we have a N elements with k elements that are defective and we are going to take a sample of n elements. So, replacing N by 100, k by 7 and n by 3, we get:

Now, the probability of rejecting the shipment is the probability that at least one iPad of the sample is defective, so:

Then:

Finally, the probability of rejecting the shipment is:
