Answer:

x = 37

Step-by-step explanation:

Vertically opposite angles are equal

Therefore,  2x + 6 = 80

Subtract 6 from both sides:   2x = 74

Divide both sides by 2:   x = 37

2x+6=80

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.

chord ab intersects chord hi at point c.the length of cb is 4 times the length of ac.find the length of ac
Mkey [24]
Chord AB = ?
Chord AB = AC + CB

Chord HI = HC + CI
HC = 7
CI = 28
Chord HI = 7 + 28 = 35

Chord AB = Chord HI

CB is 4 times the Length of AC. Let AC be X.

x + 4x = 35
5x = 35
x = 35/5
x = 7

AC = x = 7
CB = 4x = 4(7) = 28

If a car can travel 250 miles on 10 gallons of fuel, how many gallons are required to travel 1,325 miles?
Varvara68 [4.7K]
1325                      250
-------          =        -------      
    x                           10

1325(10) = 250x

13250/250 = 250x/250

x = 53 

53 gallons are required to travel 1325 miles

hope this helps
