Answer:
Yes
Step-by-step explanation:
Given that :
CHAIN A:
Sample size n1 = 30
Sample standard deviation of waiting time s1 = 21.2
CHAIN B:
Sample size, n2 = 28
Sample standard deviation of waiting time s2 = 31.4
Null hypothesis H0: s1 = s2
Alternative hypothesis H1: s1 < s2
Test statistic ; Ftest : s1² / s2²
Ftest = 21.2^2 / 31.4^2
= 0.4558399
P value from F statistic : = 0.02 (using p value calculator)
Since the pval < 0.05
Then we reject the Null ; Chain A waiting time is more consistent
Answer:
RS=19
Step-by-step explanation:
Simplify both sides of the equation.
They're asking you to fill in the distance from the sun to the planet in kilometers.
Mercury is 57,900,000 kilometers from the sun.
Venus is 107,477,000 km from the sun at its closet point.
Earth is the third planet closest to the sun, and at it's closest point is about 146,000,000 km away.
Mars, at its closest point to the sun, is 206,000,000 km away.
Jupiter's average distance from the sun is 779,000,000 km.
Saturn's average distance from the sun is 1.4 billion km.
Uranus' average distance from the sun is 2.88 billion km.
Lastly Neptune's average distance from the sun is 4.5 billion km.

Because, well, without them how are you able to add and subtract fractions :D
It is according to the laws of mathematics that you cannot add or subtract fractions that have different denominators to each other. So you need to make your fractions having the same denominator so that they are able to be added or subtracted (hence the equivalent fractions - making the denominators the same are making the fractions equivalent)
Answer:
A. 2
Step-by-step explanation:
Count the steps to get to the both points.
From (-3, -2) to (-1, 2), it gets up by 4 and move to the right by 2.
Rise ÷ Run = 4 ÷ 2 = 2
