Answer:
Parallel lines are lines that never meet and are always the same distance apart. Lines X, Y, and Z are all parallel to each other.
Step-by-step explanation:
Answer:
See answers below:
Step-by-step explanation:
Using corresponding angles properties, angles opposed by the vertex, and supplementary angle properties, we get:
<1 = 75 degrees
<2 = 105 degrees
<3 = 44 degrees
<4 = 136 degrees
<5 = 44 degrees
<6 = 90 degrees
<7 = 46 degrees
<8 = 75 degrees
<9 = 105 degrees
<10 = 75 degrees
<11 = 59 degrees
<12 = 46 degrees
<13 = 75 degrees
<14 = 105 degrees
<15 = 44 degrees
<16 = 136 degrees
<17 = 44 degrees
<18 = 136 degrees
The magnitude of the displacement the person traveled is 0.
Solution:
Starts driving and 3 km east to a store.
⇒ Distance = 3 km
Displacement = 3 km
Turns around and travels 1 km west to another store.
⇒ Distance = 1 km
Displacement = -1 km
Person travels 2 km west, back to the starting point.
⇒ Distance = 2 km
Displacement = -2 km
Magnitude of the displacement this person traveled
= 3 km + (-1 km) + (-2 km)
= 3 km - 1 km - 2 km
= 3 km - 3 km
= 0
The magnitude of the displacement the person traveled is 0.
Answer:
<em>The sample mean (x⁻) = 80 hours is a point estimate for the mean lifetime of the batteries</em>
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<u><em>Point Estimate:-</em></u>
The sample mean (x⁻) is a point estimate of the Population mean 'μ'
Given data
mean of the sample (x⁻) = 80 hours
<em>Therefore The sample mean (x⁻) = 80 hours is a point estimate for the mean lifetime of the batteries.</em>
<em>and </em>
The sample standard deviation (s) is a point estimate of the Population standard deviation(σ).
Given data
standard deviation of the sample (s) = 20 hours
<em>Therefore The sample standard deviation (s) = 20 hours is a point estimate of the Population standard deviation(σ).</em>
