Hey, heres some homework I have no idea on.
Tems11 [23]
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>

If two lines intersect and one of the angles formed has a measure of 67º, which of the following statements are true? Explain yo
Karo-lina-s [1.5K]

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°

1. Suppose you have just received a shipment of 100 iPads where 7 iPads are defective. To determine whether or not you will acce
Lyrx [107]

Answer:

p(x\geq 1)=0.1975

Step-by-step explanation:

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

p(x)=\frac{kCx*((N-k)C(n-x))}{NCn}

Where aCb=\frac{a!}{b!(a-b)!}

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:

p(x)=\frac{7Cx*((100-7)C(3-x))}{100C3}

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

p(x\geq 1)=p(1)+p(2)+p(3)

Then:

p(1)=\frac{7C1*((100-7)C(3-1))}{100C3}=0.1852\\p(2)=\frac{7C2*((100-7)C(3-2))}{100C3}=0.0121\\p(3)=\frac{7C3*((100-7)C(3-3))}{100C3}=0.0002

Finally, the probability of rejecting the shipment is:

p(x\geq 1)=0.1852+0.0121+0.0002=0.1975
