Answer:

X = 60

Step-by-step explanation:

All angles in a triangle have to add up to 180 degrees. Therefore we can set up an equation like this:

40 + (x + 20) + x = 180

Now, all we have to do is solve:

Combine:\\60 + 2x = 180\\Minus:\\2x = 120\\Divide:\\x = 60

Therefore, x is equal to 60.

We can check this by plugging x into the angles and adding all of them up :

40 + (60 + 20) + 60 = 180

40 + 80 + 60 = 180

120 + 60 = 180

180 = 180

The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh, where s is the atmospheric pressure, d is the density of the liquid, and gas the acceleration due to gravity.

p = s + dgh

dgh = p - s

h = (p - s)/dg

Which formula represents h in terms of p, s, d, and g? Formula B is correct.

If the P-value of a test of significance is greater than the level of significance, then which of these conclusions are appropri
VLD [36.1K]

Answer:

Step-by-step explanation:

In general, when the p-value is "high" (ie greater than or equal to the significance level), our sample results could have occurred by random chance alone when null hypothesis H0 is true. So we cannot reject H0 with high p-values. That doesn't mean we can accept H0 as being true. Statistical hypothesis testing is used to determine whether the result of a data set is statistically significant. This test provides a p-value, representing the probability that random chance could explain the result. In general, a p-value of 5% or lower is considered to be statistically significant. If the P-value is less, reject the null hypothesis. If the P-value is more, keep the null hypothesis. 0.003 < 0.05, so we have enough evidence to reject the null hypothesis and accept the claim.A null hypothesis is a hypothesis that says there is no statistical significance between the two variables in the hypothesis. ... In the example, Susie's null hypothesis would be something like this: There is no statistically significant relationship between the type of water I feed the flowers and growth of the flowers.

Find the missing probability.
Westkost [7]

The value of the missing probability is:

P(A) = 1/5

So the correct option is D.

<h3>How to find the missing probability?</h3>

First, we know that:

P(A∩B) = probability that events A and B are true = 3/100

And we also know that:

P(B|A) = probability that event B is true given that event A is true = 3/20

Here we have the rule:

P(A∩B) = P(B|A)*P(A)

Replacing the first two:

3/100 = (3/20)*P(A)

Solving for P(A), we get:

(3/100)*(20/3) = 1/5 = P(A).

So we conclude that the correct option for the missing probability is the one in option D.
