Mathematics

Ainat [17]3 years ago

To solve this equation you need to solve for the variable x. There are more than one way you can to this but I find substitution method to be viable.

x=10, we know this because 10/2= 5 and 5-1=4. Also 10/5=2 and 2+2=4.

please vote my answer brainliest. thanks!

Suppose that each time Diana Taurasi takes a 3-point shot, she has a 37% probability of success, independent of all other attemp
stepan [7]

Answer:

The variance of the total number of points she scores from these shots is 4.8951.

Step-by-step explanation:

For each 3-point shot that she takes, there are only two possible outcomes. Either she makes it, or she misses. This means that we can solve this problem using concepts of the binomial probability distribution.

Binomial probability distribution:

Probability of exactly x sucesses on n repeared trials, with p probability.

Has the variance given by:

Var(X) = np(1-p)

In this problem, we have that:

She takes 7 shots, each one with a 37% probability of success. So n = 7, p = 0.37. So:

Var(X) = np(1-p) = 7*0.37*0.63 = 1.6317

This is the Variance of the number of shots that she makes. Each shot is worth three points. So the variance of the total number of points she scores from these shots is 3*1.6317 = 4.8951.

Answer:

70

Step-by-step explanation:

we have the angle of vertex in the isosceles triangle = 180-2*bottom coner= 180-65/2=50

3 angles in the equilateral triangle are equal to 60

we have 50 + 60 +h =the angle of PQR =180

h=70

Which of the following scales of measurement lacks numeric properties?
Rus_ich [418]

Answer: A

Step-by-step explanation:

The nominal scale by definition only deals with non-numeric or non-quantitative variables or where numbers have no numerical value. The nominal scale uses tags or labels instead of number to classify or identify an object being measured.
