what is a multiplication expression that is equal to 2/3 divided by 6
Answer:
1/9
Step-by-step explanation:
On each trial of an experiment, a participant is presented with a constant soft noise, which is interrupted at some unpredictable time by a slightly louder sound. The time it takes for the participant to react to the louder sound is recorded. The following list contains the reaction times (in milliseconds) for 8 trials of this experiment:
486, 358, 395, 759,496, 692, 353, 306 0
(a) What is the mean of this data set? If your answer is not an integer, round your answer to one decimal place.
(b) What is the median of this data set? If your answer is not an integer, round your answer to one decimal place.
(c) How many modes does the data set have, and what are their values?
Answer:
480.6 ; 440.5, 8 mode values
Step-by-step explanation:
Given that :
Given the data :
486, 358, 395, 759,496, 692, 353, 306
Rearranged data: 306, 353, 358, 395, 486, 496, 692, 759
The mean:
Σx/ n
n = sample size = 8
Σx = sum of all data values = 3845
Mean = 3845 / 8
Mean = 480.6
The median :
0.5(n + 1)th term
0.5(8 + 1) th term
0.5(9)th term
= 4.5term
(4th + 5th term) / 2
(395 + 486) / 2
= 440.5
The mode = most frequently occurring data value ; since all the data values have a frequency of 1, then the number of modes = 8.

Find the probability of rolling divisors of 24
Answer:
5/6 is the probability
Step-by-step explanation:
Factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24 and rolling a 6-sided die you can get 1, 2, 3, 4, 5, 6 so 5 is the only thing you can roll that isn't a factor of 24 so

Ariana invested $400 in an account paying an interest rate of 3.8% compounded monthly. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 11 years?
Answer:
After 11years there'll be$602.880
Step-by-step explanation:
Amount after 11years
=$400(1+3.8/100)¹¹
=$602.880
The after 11 years the amount will be $602.880
We have given that,
Ariana invested $400 in an account paying an interest rate of 3.8% compounded monthly.
What is the formula for the future value on simple interest?[tex]A=p(1+r)^n[/tex]
Amount after 11 years,
[tex]P=$400r=3.8[/tex]

Imagine a researcher posed a null hypothesis that in a certain community, the average energy expenditure should be 2,100 calories per day. He randomly sampled 100 people in that community. After he computed the t value by calculating a two-tailed t-statistic, he found that the probability value was 0.10. Thus, he concluded:
Answer: I fail to reject the Null Hypothesis H₀ and conclude that average energy expenditure is 2100 calories per day.
Step-by-step explanation:
Null Hypothesis H₀ : average energy expenditure is 2100 calories per day
Alt Hypothesis H₁: average energy expenditure is NOT 2100 calories per day
now since
P-value (0.10) > ∝ (0.05),
then he should say;
i fail to reject the Null Hypothesis H₀ and conclude that average energy expenditure is 2100 calories per day.

What is the unit rate for meters per second if a car travels 450 meters in 25 seconds?
Answer:
18m/s
Step-by-step explanation:
Formula = 450 meters in 25 seconds
Average speed = 450m/25s
The unit rate is equivalent to 18m/s.
[Basically, just divide 450 meters by 25 seconds to get 18 meters per second. 18 is the unit rate :) ]
