Answer: 6cm
Step-by-step explanation:
Height of the triangle = 6cm
Area = 18cm
Base = Unknown
Area of a triangle= (base × height)/2
18 = (base × 6)/2
18 × 2 = base × 6
36 = base × 6
Base = 36/6
Base = 6cm
Answer:
P (z) = -1.5094
Step-by-step explanation:
We have to find P-value (that means we have to calculate the test value to evaluate a proportional hypothesis
From problem statement
P₀ = 0,44 44 % from publisher report
The claim :
350 = n random sample
P = 0,40 40 %
To calculate P value
P ( z ) = ( P - P₀ ) / √(P₀*Q₀)/n
then P ( z ) = - 0.04 / √(0,44)(0,56)/350 P(z) = - 0.04/0,02
P (z) = -1.5094
