Answer:
6/7.
Step-by-step explanation:
The sum of the 2 numbers is greater than 5 in 6 out of 7 throws.
So the required experimental probability is 6/7.
Answer: 42
Step-by-step explanation:
Here given numbers : 28 and 63
so Mean = √x * y
let x = 28 and y = 63
<em>So mean proportion between them is:</em>
M = √63 * 28
M = √1764
M = 42
- therefore the mean proportion between 28 and 63 is 42

Answer:
A = 139.25 cm^2
Step-by-step explanation:
The composite shape is made up of a square with side 10 cm and a semicircle with diameter 10 cm. The area of the composite shape is the sum of the two areas. The diameter of the semicircle is the side of the square, and the radius of the circle is half of the diameter.
A = s^2 + (1/2)(pi)r^2
r = d/2 = s/2
A = (10 cm)^2 + (1/2)(3.14)(10 cm/2)^2
A = 100 cm^2 + (1/2)(3.14)(25 cm^2)
A = 139.25 cm^2
Answer:
A. It will definitely be a t-test
Step-by-step explanation:
T-test is a type of inferential statistic test which used to determine whether there is a significant difference between mean of two group sets or variables.The t-test technique is widely used in hypothesis testing in statistics. When the model building for game play is determine through regression analysis, it will require t-test to be conducted to reach a conclusion.
