Answer:
Step-by-step explanation:
1) The sample and the population of this study is the friends who replied his email which includes in his contact list. then, the number of the replied to his email are 9 friends.
population: the whole friends include in his contact list.
3) Type I error occurs when one incorrectly rejects the null hypothesis
Here there is possibility of type I error
14 pounds 9 ounces = 233 ounces
9 pounds 14 ounces = 158 ounces
233-158=75 ounces=4 pounds 11 ounces
The ramp will form a triangle with height 2ft and base 6ft.
The length of the ramp will be the hypotenuse of this triangle.
length² = height² + base²
length = √(height² + base²)
length = √(2² + 6²)
length = √(4 + 36)
length = √40
length = 6.3ft
Therefore, the ramp will be 6.3ft long.
To find area you need to multiply
length x width
Since 49 can be square rooted it equals seven
L x W = Area
Area = 7 x 7
Area = 49
Meaning since it’s a square the perimeter is
7 by 7 by 7 by 7 in other words 7 + 7 + 7 + 7 OR 7 x 4(equal sides)
