In December it snowed 2 days for every 8 days it did not snow what percent of the days in December did it snow

sergey [27]

I think it might be 20%. If in a total of 10 days it only snowed 2, then you could take 2/10, which is .2, then multiply by 100 to make it a percentage... which would be 20%.

Need help with a math question

tatyana61 [14]

ANSWER

$x = 71 \degree$

EXPLANATION

The sum of the exterior angles of a polygon is 360°

The angles were given in terms of x.

We add all and equate to 360° to obtain.

$x + (x - 6) + (x + 4) + (x + 2) + (x + 5) = 360 \degree$

This implies that,

$5x + 5 = 360$

$5x = 360 - 5$

$5x = 355$

$x = \frac{355}{5}$

$x = 71 \degree$

The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000

mel-nik [20]

Answer:

0.018 is the required probability.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 60,000 miles

Standard Deviation, σ = 1500 miles

We are given that the distribution of tread life is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(brand will last between 56,850 miles and 57,300 miles)

$P(56850 \leq x \leq 57300) = P(\displaystyle\frac{56850 - 60000}{1500} \leq z \leq \displaystyle\frac{57300-60000}{1500}) = P(-2.1 \leq z \leq -1.8)\\\\= P(z \leq -1.8) - P(z < -2.1)\\= 0.0359 - 0.0179 = 0.018= 1.8\%$

$P(56850 \leq x \leq 57300) = 1.8\%$

0.018 is the probability a certain tire of this brand will last between 56,850 miles and 57,300 miles.
