Answer:
B. [0.802], [0.978]
Step-by-step explanation:
n=49
p=.89
confidence level of 95% has a z value of 1.960
z*= 1.960
z*=qnorm(1.95/2)
p+/-z* multiplied by sqrt[ P * ( 1 - P ) / n ]
p+/-z*times(√(p)(1-p)/n)
.89+/-1.960* (square root of (.89)(.11)/49))

Answer:
96 cm squared
Step-by-step explanation:
A rhombus has 4 edges of equal length. If it has perimeter of 40cm, then each length would be
40cm
4 = 10cm
Divide the rhombus into 4 right-angle triangle by cutting along the 2 diagonals.
Each right-angle triangle will have a hypotenuse of 10cm and one other edge with length
12cm
2 = 6cm
Use Pythagoras Theorem to find the length of the remaining edge.
√(10cm) squared − (6cm) squared = 8cm
Now find the area of the triangle.

2 × 6cm ×8cm =24cm squared
Since the original rhombus was made up of four such triangles, the area of the rhombus would be
24cm squared × 4 = 96cm squared
