Hello, and thank you for posting your question here on brainly.

This fraction needs to be simplified to be able to figure it out.

The greatest common divisible is 2.

Divide the numerator and denominator by 2.

6/4 = 3/2

Now, do the division.

3/2 = 1.5

1.5 is rational.

Hope this helps! ☺♥

It is rational because when you try to devide fraction and the answer stop ( like 3 or 3.45 or 3.4576 etc) and not go on forever ( like 3.098766557.......) that means its rational..
Im not really good at explaining but I hope it helps a even little

Naddika [18.5K]

Answer:

112

Step-by-step explanation:

Given that in a study of the stability of IQ scores, a large group of individuals is tested once at age 18 and again at age 35.

Age 18: average score = 100, SD = 15

Age 35: average score = 100, SD = 15, r = 0.80

Let us obtain regression equation of y on x.

Let y be the scores at age 35 and x at age 18

Slope = r(s_y/s_x) = 0.8(\frac{15}{15} )=0.80

The line passes through (100,100) being average of x and y

Hence regression line would be

y-100=0.8(x-100)\\y = 0.8x+20

a) Here given that x =115

Hence y=0.80(115)+20\\=112

the average score at age 35 for all the individuals who scored 115 at age 18, would be 112.

b) Prediction also would be the same 112.

Suppose that Stephen is the quality control supervisor for a food distribution company. A shipment containing many thousands of
kondaur [170]

Answer: 0.8031

Step-by-step explanation:

Binomial distribution:

For a binomial variable x,

The probability of getting success in x trials = P(X=x)=^nC_xp^x(1-p)^{n-x}

, where n = Total trials .

p= Probability of getting success in each trial.

For the given situation , we take x as the number of damaged apple .

Given : The proportion of damaged apples : p=0.15

n= 10

Then, the probability that his sample will contain at least one damaged apple.  :-

P(x\geq1)=1-P(x

Hence, the required probability = 0.8031
