Given that the measure of angle 6 is 1/8 of measure of angle 4. Find the measures of these two angles if a∥b.
vredina [299]

Answer:

see explanation

Step-by-step explanation:

Let ∠4 be x then ∠6 is \frac{1}{8} x

∠4 and ∠6 are same side interior angles and are supplementary, thus

x + \frac{1}{8}x = 180

Multiply through by 8 to clear the fraction

8x + x = 1440, that is

9x = 1440 ( divide both sides by 9 )

x = 160

Hence ∠4 = 160° and ∠6 = 160° ÷ 8 = 20°

The standard deviation is  4 games

A standard deviation (or σ) is a measure of how dispersed the facts are in relation to the mean. Low general deviation method statistics are clustered around the imply, and excessive trendy deviation indicates facts are more unfold.

Don't forget the statistics set: 2, 1, 3, 2, four. The mean and the sum of squares of deviations of the observations from the mean will be 2. 4 and 5.2, respectively. as a consequence, the same standard deviation could be √(5.2/5) = 1.01.

In data, the same old deviation is a degree of the quantity of variant or dispersion of a set of values. A low preferred deviation indicates that the values tend to be close to the mean of the set, while a high general deviation shows that the values unfold out over a much broader variety.

Given that,

mean = μ = 18

standard deviation = Σ =  6

n = 2

μ  x =  μ = 18 games

√  x = Σ / √ = 6  

√2 = 4 games

4vir4ik [10]

Answer:

23.5(to the nearest tenth)

Step-by-step explanation:

pythagoras theorem states

c^2= a^2+ b^2

a= 23

b=5

c^2= 529+25

c^2= 554

c= square root of 554

c = 23.5 (approximately)

Answer:

0.3 galloons of water.

Step-by-step explanation:

We know that 1/5 galloons of water fills 2/3 of the bin.

So, we can write the following fraction:

\frac{\frac{1}{5}\text{ galloons}}{\frac{2}{3}\text{ bin}}

We want to find how many galloons will fill the entire bin or 1 whole bin. So, we can write the following proportion:

\frac{\frac{1}{5}\text{ galloons}}{\frac{2}{3}\text{ bin}}=\frac{x\text{ galloons}}{1\text{ bin}}

To find our answer, we need to solve for x.

So, let's cross-multiply. This yields:

\frac{2}{3}x=\frac{1}{5}

Multiply both sides by 3:

3(\frac{2}{3}x)=3(\frac{1}{5})

The left side simplifies. Multiply on the right:

2x=\frac{3}{5}

Now, multiply both sides by 1/2:

\frac{1}{2}(2x)=\frac{1}{2}(\frac{3}{5})

Simplify the left. Multiply on the right:

x=\frac{3}{10}

So, 3/10 of 0.3 of a gallon of water will fill the entire bin.

And we're done!
