Answer:

I can conclude that Sally went down the slide. I used deductive reasoning to get my answer. Sally said that if it was sunny, she would go to the park. She also said that if she does go to the park, she will go down the slide. Since Sally did go to the park, I know that she did go down the slide. Based on the information I have, I can use deductive reasoning to get to my answer.

Tom [10]

Answer:

the probability that the sample variance exceeds 3.10 is 0.02020 ( 2,02%)

Step-by-step explanation:

since the variance  S² of the batch follows a normal distribution , then for a sample n of  20 distributions , then the random variable Z:

Z= S²*(n-1)/σ²

follows a χ² ( chi-squared) distribution with (n-1) degrees of freedom

since

S² > 3.10 , σ²= 1.75 , n= 20

thus

Z > 33.65

then from χ² distribution tables:

P(Z > 33.65) = 0.02020

therefore the probability that the sample variance exceeds 3.10 is 0.02020 ( 2,02%)

Jose has 1000$ in his savings account. it pays out 5% interest what is his balance after 1 year
NARA [144]

The most appropriate choice for simple interest will be given by- Balance of Jose after 1 year is $1050

What is simple interest?

Simple interest is the interest applied on the principal value after charging some certain percentage of rate for some certain amount of time.

If the principal value is p, rate is r % per annum and time is t years

Simple interest is calculated as

SI = p ₓ r ₓ t / 100

Here,

Principal for Jose = $1000

Rate = 5%

Time = 1 year

Simple interest = 1000x5x1/100

                         = $50

Amount = $(1000+50)

             = $1050

Balance of Jose after 1 year is $1050
