Answer:
The initial cost of the cell phone was $364
Step-by-step explanation:
Since there was a 30% markup, 70% of the new cost is the initial cost. Multiply 520 by 0.7 on a calculator and you get 364
Tan inverse 28/19 is the answer
Answer: So zero represents the point when locating a point on the number line like negatives and positives
Given:
The table of value of a linear function.
To find:
The linear function in slope intercept form.
Solution:
Slope intercept form:

Where, m is slope and b is y-intercept.
Consider any two points from the given table.
It is clear that the linear function passes through the points (1,0) and (2,5). So, the equation of the linear function is

Using distributive property, we get


Therefore, the slope intercept form of the given linear function is
.
Answer:
The expected number of volunteers in the sample with Genetic condition B is 0.6.
Step-by-step explanation:
The probability of a being born with Genetic Condition B is p = 1/60 = 0.017.
Find the most likely number of the 33 volunteers to have Genetic Condition B.
We can calculate as if it was a binomial distribution, with sample size n=33 and p=0.017.
The expected value of a binomial distribution random variable is calculated as:

The expected number of volunteers in the sample with Genetic condition B is 0.6.
