You can use y = {-1, x ≤ 0 and y = {x - 1, x > 0 as two functions for your piecewise function. The first function will be a horizontal line. The second function will be a straight line with a slope of 1 and y-intecept of -1. Messaged you the graph.
answer:
we reject null and conclude that this manufacturers claim is false
Step-by-step explanation:
p = 30% = 0.30
p^ = 93/150 = 0.62
we state the hypothesis
H0: p = 0.30
h1: p not equal to 0.30
we find the z test stattistics




z = 8.5538
at alpha = 0.05
z-critical = Z₀.₀₅/₂ = Z₀.₀₂₅
= 1.96
we compare z critical with the test statistic
z statistic > z critical so we have to reject H₀ and conclude that the manufacturers claim is not valid at 0.05 level of significance.
Answer:
A.) 52%
Step-by-step explanation:
14+12=26
26/5=5.2
you now have 5.2, then you take the decimal and move it over to make a percentage.
Answer:
562
Step-by-step explanation:
you take 13 times 2 times 2 then 17 times 2 times 2 then 13 times 17 times 2 then add those numbers together
