Distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(-5,8)(10,-7)
d = sqrt (10 - (-5)^2 + (-7 - 8)^2
d = sqrt (10 + 5)^2 + (- 15^2)
d = sqrt (15^2) + (-15^2)
d = sqrt 225 + 225
d = sqrt 450
d = 21.21
Answer:
Mean height of 159
Step-by-step explanation:
Add 153 and 165, then divide by 2 to find the average of 159.
The answer should be 74% probability
35/50+5/50-3/50= 37/50->74%
Because it accurately depicts the distribution of values for many natural occurrences, it is the most significant probability distribution in statistics.
The most significant probability distribution in statistics for independent, random variables is the normal distribution, sometimes referred to as the Gaussian distribution. In statistical reports, its well-known bell-shaped curve is generally recognized.
The majority of the observations are centered around the middle peak of the normal distribution, which is a continuous probability distribution that is symmetrical around its mean. The probabilities for values that are farther from the mean taper off equally in both directions. Extreme values in the distribution's two tails are likewise rare. Not all symmetrical distributions are normal, even though the normal distribution is symmetrical. The Student's t, Cauchy, and logistic distributions, for instance, are all symmetric.
The normal distribution defines how a variable's values are distributed, just like any probability distribution does. Because it accurately depicts the distribution of values for many natural occurrences, it is the most significant probability distribution in statistics. Normal distributions are widely used to describe characteristics that are the sum of numerous distinct processes. For instance, the normal distribution is observed for heights, blood pressure, measurement error, and IQ scores.

Answer:
The mass of cocoa in chocolate candy is 3 g.
Step-by-step explanation:
30gr chocolate candy, mark on its packaging that it contains 10% cocoa, how many grams of cocoa does this represent?
mass of chocolate candy = 30 g
cocoa contains = 10 %
Now the mass of cocoa = 10 % of 30 g = 0.1 x 30 = 3 g
Mass of cocoa in the candy is 3 g.
