Answer:
You can multiply 4 and 5 by a number, and it will be equivalent.
Let's use the number 3.
4 x 3=12
5 x 3=15
So, it will be 12:15
Answer:
-3/2 < x < 5......................
Answer:
A) H1: π < 0.10
Step-by-step explanation:
<u>One tailed test</u>:-
A test of any statistical hypothesis where the alternative hypothesis is one tailed ( right tailed or left tailed) is called a one - tailed test.
H1: μ < μ0 (left tailed test)
H1: μ > μ0 (right tailed test)
<u>two tailed test</u>:-
In a test of statistical hypothesis where the alternative hypothesis is two tailed , we assume that the null hypothesis
H0: μ = μ0 against the alternative hypothesis
H1: μ ≠ μ0
conclusion:-
given data It is claimed that in a bushel of peaches, fewer than 10% are defective so alternative hypothesis
H1: μ < 0.10
Answer:
yes because radius makes 90 degree with it. using Pythagoras theorem, it is seen that 5^2 = 3^2 + 4^2
Answer:
Step-by-step explanation:
Since the outdoor ice skating arena is in the shape of a circle, we would determine its area by applying the formula for determining the area of a circle which is expressed as
Area = πr²
Where
π is a constant whose value is 3.14
r represents the radius of the circle
From the information given,
Diameter = 42 feet
Radius = diameter/2 = 42/2 = 21 feet
Therefore,
Area = 3.14 × 21² = 1384.74 square feet
Rounding up to the nearest whole number, area of the outdoor ice skating arena would be 1385 square feet
