What is the main cause of tides?

1 answer:

I'm not exactly sure on this one but please bare with me haha

High tides and low tides are caused by the moon and tides are really all about gravity(hence why all of these answers have gravitational in them). And, when we are talking about "daily tides" it's the moon that causes them.

The moon's gravity draws in various areas of our world as it rotates. Since the moon is just 1/100th the mass of the Earth, it has enough gravity to shift objects about. The ocean on the moon's far side is still trying to bulge out against it. A high tide is what we term this bulge. (Water is easy to move around too)

This is tidal force, and there are differences between high tides and low tides.

Answer:

Step-by-step explanation:

$\boxed{slope = \frac{y1 - y2}{x1 - x2} }$

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate

Thus, using the above formula,

$slope = \frac{2 - ( - 1)}{5 - ( - 3)}$

$slope = \frac{2 + 1}{5 + 3}$

$slope = \frac{3}{8}$

Suppose that the mean and standard deviation of the scores on a statistics exam are 78 and 6.11, respectively, and are approxima

kiruha [24]

Answer:

0.7422 = 74.22% of scores are above 74.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 78, \sigma = 6.11$

Calculate the proportion of scores above 74.

This is 1 subtracted by the pvalue of Z when X = 74. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{74 - 78}{6.11}$

$Z = -0.65$

$Z = -0.65$ has a pvalue of 0.2578

So 1-0.2578 = 0.7422 = 74.22% of scores are above 74.
