Opposite angles are equal.

Opposite sides are equal and parallel.

Sum of any two adjacent angles is 180°

Doss [256]

Answer:

Step-by-step explanation:

a³-b³=(a-b)(a²+ab+b²)

6³-1=6³-1³=(6-1)(6²+6*1+1²)=5×43

Using the graph, what does f(8) equal?<br> PLEASE I NEED SO MUCH HELP!!
Shtirlitz [24]

Answer:

Step-by-step explanation:

The question is not terrifically worded. What it means is "What is the y value when x = 8" That's what f(8) conveys to you.

The answer (though zero is not marked and should be) is 1 unit above 0.

The answer is f(8) = 1 He's heading back.

1. Undeliverable Mail Pieces. Of the 155 billion mailpieces the U.S. Postal Service (USPS) processed and delivered in 2017, 4.3%
Juli2301 [7.4K]

Answer:

The sampling distribution is, p = center = 0.043

The standard deviation of the sample, s = 6.0015×10⁻⁴

The shape is normal

Step-by-step explanation:

Here we have the standard deviation of a sample proportion, given by the following relation;

Standard \ deviation \ of\ \hat p = \sqrt{\frac{p(1-p)}{n} } =  \sqrt{\frac{0.043 \times (1-0.043)}{114250} } = 6.0015 \times 10^{-4}

The center = p = 4.3% or 0.043

The shape is found by the value of n×p hence;

114250 × 0.043 = 4912.75 > 10 and

n(1 - p) = 114250 × (1 - 0.043) = 109337.25 also > 10 hence the shape is normal.
