Kryger [21]

Answer:

The answer is R

Explanation:

Since there are 4 sides, we divide 360 by 4 to find the amount needed to turn to move from one side to another. So we move P one side, landing on Q, then we move it 3 sides counter-clockwise (270/90=3 sides), landing on R

The claim is that the white blood cell counts of adult females are normally distributed, with a standard deviation equal to 1.6

maxonik [38]

Answer:

78.46

Step-by-step explanation:

Given that

Pop. Standard deviation = 1.61

Sample standard deviation = 2.15

Sample mean = 7.47

Sample size = 45

Recall that

Test stat for chi square

= (n - 1) (sample standard dev/pop standard dev)^2

= 45 - 1 (2.15/1.61)^2

= 44(1.3354)^2

= 44 × 1.78329

= 78.46

Y=f(x) = (1/2)<br> Find f(x) when x = 1

sammy [17]

The value of function on x=1 is 0.5

Step-by-step explanation:

In order to find the value of a function on given input, the input is put at the place of variable in the function.

Given function is:

$f(x) = (\frac{1}{2})^x$

We have to find the value of function on x = 1

Putting x = 1 in function

$f(1) = (\frac{1}{2})^1\\= \frac{1}{2}\\= 0.5$

Hence,

The value of function on x=1 is 0.5

A college student is taking two courses. The probability she passes the first course is 0.67. The probability she passes the sec

andrezito [222]

Answer:

0.58 = 58% probability she passes both courses

Step-by-step explanation:

We can solve this question treating the probabilities as a Venn set.

I am going to say that:

Event A: She passes the first course.

Event B: She passes the second course.

The probability she passes the first course is 0.67.

This means that $P(A) = 0.67$

The probability she passes the second course is 0.7.

This means that $P(B) = 0.7$

The probability she passes at least one of the courses is 0.79.

This means that $P(A \cup B) = 0.79$

a. What is the probability she passes both courses

This is $P(A \cap B)$ .

We use the following relation:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$P(A \cap B) = P(A) + P(B) - P(A \cup B) = 0.67 + 0.7 - 0.79 = 0.58$

0.58 = 58% probability she passes both courses
