Answer: this is very hard and i was wondering if there is more info
Step-by-step explanation:
The critical values for a Chi-square distribution with 80% confidence level and sample size of 15 (thus 14 degrees of freedom) are: χ2L = 18.475 and χ2R = 8.897.
The question is asking for the critical values for a Chi-square distribution which can be found using Chi-square tables usually found in statistics textbooks or online. The critical values refer to the boundary values for the acceptance region of a hypothesis test.
When trying to find the critical values for an 80% confidence level with 14 degrees of freedom (since degrees of freedom = n - 1 for sample, thus 15 - 1 = 14), you need the 90th percentile for the χ2L and the 10th percentile for the χ2R (since α = 20%, then α/2 = 10%).
Using a Chi-square table for these percentiles, we get:
χ2L = 18.475
χ2R = 8.897

Answer:
49/144
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 49 and 144 is 1
Divide both the numerator and denominator by the GCD
49 ÷ 1
144 ÷ 1
Reduced fraction:
49
144
Therefore, 49/144 simplified to lowest terms is 49/144.
Answer:
7/12
Step-by-step explanation:
7 goes into 49 7x times
and
12 goes into 144 12x times
So if we simplify this, the answer would be
Answer: 13,879 days
If Joan's father is 38 years old today, that means that he was born in 1982. (2020-38=1982).
If we multiply 38 years by 365 days per year, we get 13,870 days.
But we need to take into account leap years, which happen every 4 years! In a leap year, there's an extra day in February. There have been 9 leap years since Joan's father was born.
So, we add 9 days to 13870 days, to get: 13,879 days.
Please give me Brainliest if this helped! :)
Joan's father, who is 38 years old, would be 13,870 days old. This is calculated by multiplying 38 years by 365 days/year.
To calculate how many days old Joan's father is, you simply need to multiply his age in years by the number of days in a year. Since we typically consider a year to have 365 days, the calculation is as follows: 38 years * 365 days/year. The answer, therefore, is 13,870 days. The main concept here is the conversion of units, in this case converting years to days. Remember to always consider the number of units in one when converting.

Complete the equation for the relationship between the fee and the number of hours.
Answer:
$5/ hour (her hourly wage) and y = 5x + 10 (equation)
Step-by-step explanation:
y = ax + 10
(a = the price per hour, 10 = number added AKA fee)
We plug in the point given (5 hours, $35) = (5, 35) and get:
35 = 5a + 10 -->
25 = 5a -->
5 = a -->
$5/ hour and y = 5x + 10
