Answer:
The correct answer will be X = 4
Step-by-step explanation:
Using Pythagoras
AB^2 + BC^2 = AC^2
2^2 + (2√3)^2 = AC^2
4 + (4*3) = AC^2
4+12 = AC ^ 2
AC ^2 = 16
AC = √16 = 4
Answer:
P (x≥ 57) = 6.7789 e^-8
Step-by-step explanation:
Here n= 100
p = 31/100 = 0.31
We formulate the null hypothesis that H0: p= 0.31 against the claim Ha: p≠0.31
The significance level is chosen to be ∝= 0.05
The test statistic x to be used is X, the number U.S. residents is to be taken which is at least 57
The binomial calculator gives the
P (x≥ 57) = 6.7789 e^-8
IF ∝= 0.05 then ∝/2 = 0.025
We observe that P (x≥ 57) is less than 0.025
Hence we reject H0 and conclude that p ≠0.31
This is true because for normal distribution the median = mean which is usually the 50 % of the data.
Answer:
alright so your first line is correct but now you want to graph another line with to do that plot the points (0,3),(-1,-1,) and (-2,-4) and put a line through those points.
Step-by-step explanation:
Answer:
So, Time taken to make 120 tarts is 2.5 hour
Step-by-step explanation:
We are given
Rovan can make 48 tarts per hour
rate of making tarts = 48 tarts / hour
we have to find time
total number of tarts =120
Total time = ( Total number of tarts)/( rate of making tarts)
now, we can plug value
and we get
So, Time taken to make 120 tarts is 2.5 hour
