The difference in the volume of the 2 wardrobes is that she wants a new wardrobe that is a foot wider than her last wardrobe.
Answer:
48 = divider 4 = divisor 54 = divider 6 = divisor
Step-by-step explanation:
Therefore, the answer to 48 divided by 4 calculated using long divison is 12 remanider 0 therefore, the answer to 54 divided by 6 calculated using long divison is 9 remanider is 0
Answer:
There is sufficient evidence to support the claim that the standard deviation of time all women spend washing their hair in the morning is 15 seconds
Step-by-step explanation:
We shall need to formulate the hypotheses but first we need to understand the claim in context of this question. The claim is that the standard deviation of time all women spend washing their hair in the morning is 15 seconds. In mathematical notation, this claim can be written as follows;
σ = 15
Clearly the claim contains an equality sign and thus it qualifies to be our null hypothesis;
H0: σ = 15
The complement of the above hypothesis will be our alternative hypothesis;
Ha: σ ≠ 15
We are then informed that the initial conclusion of the test fails to reject the null hypothesis. In short this implies that we fail to reject the claim that the standard deviation of time all women spend washing their hair in the morning is 15 seconds since this claim is our null hypothesis. If we fail to reject a claim in hypothesis testing, this implies that there is sufficient evidence to support the claim. Therefore, there is sufficient evidence to support the claim that the standard deviation of time all women spend washing their hair in the morning is 15 seconds
Answer:
Step-by-step explanation:
Diameter:
A line passing through the center of the circle touching the circle at two points, is called diameter.
OR
The chord passing through the center is diameter.
It is double of the radius.
so,
Diameter = (2) (Radius of the circle)
Radius:
Diameter divided by 2.
OR half of the diameter is called radius.
So,
Radius = (1/2) (diameter of the circle)
Area of a circle:
Area of a circle =πr^2
Using π=3.14
Area ≈ (3.14) (radius squared)
Circumference of a cricle:
It is equal to 2πr
If π=3.14, then 2π=6.28
Circumference ≈ (6.28) (radius of the circle)
