<h2>Answer:</h2><h2>Area of the kite = 80 
, Area of traingle = 40 and height of the triangle, h = 5 cm</h2>
Step-by-step explanation:
A kite is broken into two triangles
Given the base of the traingle, b = 16 cm
Height of the triangle, h = 5 cm
Area of traingle =
=
= 40
Area of the kite = area of triangle 1 + area of triangle 2
= 40 + 40
= 80
Answer:
Yes, there is sufficient evidence to support the claim that the mean cost is $1.
Step-by-step explanation:
Data Given:
The population standard deviation = $0.2
The sample mean cost = $0.93
The sample size n = 12
From above we can use the Z-test for testing the mean from the above given data.
To check whether the mean cost of newspaper is $1.00
:
= $1
:
$1
The test statistics Z =
Z =
Z = -1.212
The P-value = 2P (Z< - 1.212)
= 2 × 0.1128
= 0.2256
Since the value of P is more than the significance level; do not reject the
Conclusion: We therefore conclude that there is sufficient evidence to support the claim that the mean cost is $1.
