Answer:
the denominator of each fraction is 2
Step-by-step explanation:
The numerator of a fraction is the number above the fraction bar; the denominator is the number below the fraction bar. In the fraction ...

The denominators of both of these fractions are 2. Since they are both the same, that value (2) can be used as the common denominator of the sum or difference of these fractions:

(b) What is the probability that all bits are 0s? Round your answer to six decimal places (e.g. 98.765432). Enter your answer in accordance to the item b) of the question statement
(c) What is the probability that exactly 7 bits are 1s and 7 bits are 0s? Round your answer to three decimal places (e.g. 98.765). Enter your answer in accordance to the item c) of the question statement
Answers
Answer:
(a) 0.000061
(b) 0.000061
(c) 0.209
Step-by-step explanation:
An array of 14 bits is equally likely to be 0 or 1.
That is, P (0) = P (1) = 0.50.
(a)
Compute the probability that all bits are 1s as follows:
[tex]P(\text{All bits are 1s})=[P(1)]^{14}[/tex] ∵ the bits are independent
[tex]=(0.50)^{14}\\=0.00006103515625\\\approx 0.000061[/tex]
Thus, the probability that all bits are 1s is 0.000061.
(b)
Compute the probability that all bits are 0s as follows:
[tex]P(\text{All bits are 0s})=[P(0)]^{14}[/tex] ∵ the bits are independent
[tex]=(0.50)^{14}\\=0.00006103515625\\\approx 0.000061[/tex]
Thus, the probability that all bits are 0s is 0.000061.
(c)
Compute the probability that exactly 7 bits are 1s and 7 bits are 0s as follows:
Define X as the number of bits that 1s.
Then the random variable X will follows a binomial distribution with parameters n = 14 and p = 0.50.
The value of P (X = 7) is:
[tex]P(X=7)={14\choose 7}(0.50)^{7}(1-0.50)^{14-7}[/tex]
[tex]=\frac{14!}{7!\times 7!}\times (0.50)^{14}\\\\=3432\times 0.000061\\\\=0.209352\\\\\approx 0.209[/tex]
Thus, the probability that exactly 7 bits are 1s and 7 bits are 0s is 0.209.

Answers
Answer:
-5/9
Step-by-step explanation:
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(518×11)−(56×33)=?
Complete the multiplication and the equation becomes
518−1518=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
5−1518=−1018
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 10 and 18 using
GCF(10,18) = 2
−10÷218÷2=−59
Therefore:

According to one source, the average cumulated college student loan debt for a graduating senior is $29,400. Assume that such debt is normally distributed and that the standard deviation is $5,684. Thirty percent of these graduating seniors owe more than what amount?
Answers
Answer:
$32378.416
Step-by-step explanation:
We are asked to find: Thirty percent of these graduating seniors owe more than what amount.
More than 30% = Finding the z score of the 70% percentile.
The z score = 0.524
Hence, using z score formula:
z = (x-μ)/σ
0.524 = x - $29,400/$5,684
0.524 × 5684 = x - 29400
2978.416 = x - 29400
x = 29400 + 2978.416
x = $32378.416
Therefore, Thirty percent of these graduating seniors owe more than what amount $32378.416.

Can anyone help me solve for x and y
Answers
x = 24, y = 120
if you disagree tell me, I just substituted values.
Step-by-step explanation:
10. (6x - 7)° + (3x - 29)° = 180°
i.e they are co-interior angles:
6x + 3x - 7 - 29 = 180°
9x - 36° = 180°
9x = 216°
x = 24.
(6x - 7)° = (8y + 17)°
i.e they are vertically opposite angles;
but x = 24.
6(24) - 7 = 8y + 17
144 - 7 = 8y + 17
120 = 8y
y = 15
11. (9x + 25)° = (13x - 19)°
i.e they are corresponding angles;
25 + 19 = 13x - 9x
44 = 4x
x = 11
(13x - 19)° + (17y + 5)° = 180°
i.e they are adjacent angles;
but x = 11
13(11) - 19 +5 + 17y = 180
17y = 180 - 129
17y = 51
y = 3

students at Freeman Middle School have a choice of water milk or juice for breakfast from a survey it was determined that 50 students prefer water 100 prefer juice and 150 prefer milk. you want to know the probability that exactly 3 of 4 randomly selected students do not prefer water how could you model the scenario? This scenario can be simulated by Rolling a six-sided die (A 3 B 4 C 5 D 6 E 7 times). The (A numbers 0 to 3 B numbers 0 to 6 C number 1 D numbers 7 to 9 ) would represent students who prefer water if a number (A 0 to 3 B 0 to 6 C 1 D 7 to 9) appears only once in a set of outcomes then it will mean that three of four randomly picked students do not prefer water in that set .
Answers
Answer:
The probability that exactly three of four randomly selected students that do not prefer water is; P=125/1296= 0.096
Step-by-step explanation:
Hope this helps
The required probability that exactly 3 of 4 randomly selected students do not prefer water is 0.096.
Given that,
Students at Freeman Middle School have a choice of water milk or juice for breakfast.
From a survey, it was determined that 50 students prefer water 100 prefer juice, and 150 prefer milk.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
the probability that selected students to prefer water.
Total sample space = 300
Total desired events = 50
Pw = 50 / 300 = 1/6
the probability that selected students do not prefer water
Total sample space = 300
Total desired events = 100+150 = 250
Pmj = (250)/300
= 5/6
The probability for exactly 3 of 4 randomly selected students do not prefer water can be given as,
Preq = Pmj.Pmj.Pmj.Pw
Preq = (5/6)^3 × 1/6
Preq= 125/1296
= 0.096
Thus, the required probability that exactly 3 of 4 randomly selected students do not prefer water is 0.096.

Answer:
Step-by-step explanation: !!DISCLAIMER IM NOT ALWAYS THE SMARTEST BUT IM PRETTY SURE THIS IS RIGHT!
!well what I did. You know that 60 minutes=one hour. So I put 2 & 1/2 over 60.
Make 2 & 1/2 a improper fraction=5/2.
So 5/2 over 60
Then divide. 5/2 divided by 60 ( which is 60/1)
Then leave change flip, meaning leave the 5/2 change the division sign to multiplication, and flip, which you would flip 60/1 to 1/60
So we have 5/2 times 1/60. Multiply across. 5 times 1= 5. 2 times 60=120
So we have 5/120
Now we simplify 120 divided by 5 = 24. And 5 divided by 5 = 1
So 1/24
