Recall that the binomial distribution with parameters n, p, and r gives the probability distribution of the number of r successe

s in a sequence of n trials, each of which yields success with probability p. Here we can let "success" be defined as "finding a defective syringe." The batch contains 5% defective syringes, so there is a 5% chance that any given syringe will be found to be defective. Therefore, p = .
A random sample of nine syringes are checked for quality, so n = ______.

Answer:

0.05, 9

Step-by-step explanation:

The probability of success, p = chances of finding a defective syringe = 5%

Hence, probability of success p = 5 /100 = 0.05

The sample size, n = 9, (Given kn yhasrina

The length of a banquet table is 4 feet longer than 6 times its width. If the perimeter is 78 feet, what are the dimensions of t
harina [27]
Hello,
2(l+w)=78
Divided 2 from both side
2(l+w)/2=78/2
l+w=39 feet

l=6w+4
Replace l with 6w+4

6w+4+w=39
7w+4=39
Subtract 4 from both side
7w=35
Divided 7 from both side
w=5 feet
l=6w+4
l=6(5)+4
l=30+4
l=34 feet. As a result, the length of the rectangle is 34 feet and the width of rectangle is 5 feet. Hope it help!

brittany wants to make cookies at her school one batch of dough makes 2 dozen cookies she has 68 students at her school is it re
Anna [14]
Yes, it is reasonable for Brittany to think that she will need more than 2 batches of cookies to feed all of the people at her school.


One batch of dough makes 2 dozen cookies, or 24 cookies.
This means that two batches of dough makes 4 dozen cookies, or 48 cookies.

If Brittany only brought 48 cookies to school, some kids wouldn't get cookies.  So, we know that Brittany should probably bake more than 2 batches of cookies.

Draw and label all three side lengths and angle measures of a right triangle that has a 40° angle and a hypotenuse 10 cm long.
Elodia [21]

Answer:

Right Triangles and the Pythagorean Theorem

1.The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.

2.The side opposite the right angle is called the hypotenuse (side c in the figure).

11x+4y=-46<br> 7x-4y=10 <br> Find x and y
UNO [17]

Answer:x=-2 y=-6

Step-by-step explanation:

11x+4y=-46..........(1)

7x-4y=10..............(11)

Add (1) and (11)

11x+7x+4y-4y=-46+10

18x=-36

Divide both sides by 18

18x/18=-36/18

x=-2

substitute x=-2 in (11)

7x-4y=10

7(-2)-4y=10

-14-4y=10

Collect like terms

4y=-14-10

4y=-24

Divide both sides by 4

4y/4=-24/4

y=-6

Which polynomial is a perfect square trinomial? (4 points) 9x2 − 12x + 4 36b2 − 24b + 16 16x2 − 24x − 9 4a2 − 10a − 25
loris [4]
I believe it's 9x2-12x+4 but I'm not quite sure cause we haven't yet gone over this in class.

My friend also believes it is this (she's in a higher level math grade than me). I'm so sorry this isn't more helpful.
