if not I'm sorry
Answer: 11.667
Step-by-step explanation:
The formula to find the test statistic for chi-square test is given by :-
Given : Claim : 
Then , the standardized test statistic will be :-
Hence, the standardized test statistic 
16, Rewrite 64 as 4 to the 3 power, apply the power rule and multiply the exponents, cancel the common factor and rewrite the equation and get 4 to the 2 power, which is equal to 16!
Answer:
x ≥ 1 (how to graph is listed below)
Step-by-step explanation:
To find where we need to plot the line, we first need to solve the inequality for x:
-2x - 3 ≤ -5
(Add three to both sides)
-2x ≤ -2
(Divide both sides by -2, but we can't forget that whenever we multiple or divide by a negative number, the sign flips!)
x ≥ 1
To graph this on the number line, you would put a dot on the 1 and fill it in completely (you fill in the dot for a "___ and equal to" sign. ex. ≥, ≤)
Then you would make an arrow from the dot to the right on the number line (this is because x must be greater than or equal to 1, so it must be facing in that direction)
