Answer:
3.5/1
Step-by-step explanation:
Answer:
x=26
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
(2x-5)° +(4x-1)° + 30° = 180
Combine like terms
6x +24 =180
Subtract 24 from each side
6x+24-24 =180-24
6x = 156
Divide by 6
6x/6 =156/6
x =26
Answer: line XZ
Step-by-step explanation:
In geometry, a line is a straight mark without getting bend. It is has no thickness, hence it is one dimensional . It does not have any end . It extends in both directions up to infinity without.
From the given picture the only line XZ is extending in both directions up to infinity.
Therefore, the line shown in the figure is line XZ.
Pytharorean therum...can only be used on right triangles
a^2 + b^2 = c^2...a and b r ur legs and c is ur hypotenuse
10^2 + 24^2 = c^2
100 + 576 = c^2
676 = c^2
sqrt 676 = c
26 = c <== ur hypotenuse is 26 cm
The correct conclusion is Diver 2 had scores that were less spread out around the mean than Diver 1.
The question has to do with mean deviation
<h3>What is mean deviation?</h3>
The mean deviation is the measure of the spread or the difference between the mean and the standard deviation d = |X - σ| where
- X = mean and
- σ = standard deviation
<h3>How to find out which conclusion is true?</h3>
Since the mean diving score for Diver 1 was X₁ = 8.1 with a standard deviation of σ₁ = 1.07. The spread or deviation ,d₁ = |X₁ - σ₁|
= |8.1 - 1.07|
= |7.03|
= 7.03
Since the mean diving score for Diver 2 was X₂ = 8.8 with a standard deviation of σ₂ = 2.24. The spread or deviation ,d₂ = |X₂ - σ₂|
= |8.8 - 2.24| =
|6.56|
= 6.56
Since d₂ = 6.56 < d₁ = 7.03, we see that Diver 2 had scores that were less spread out than Diver 1.
So, the correct conclusion is Diver 2 had scores that were less spread out around the mean than Diver 1.
