A basketball is thrown with an initial upward velocity of 30 feet per second from a height of 6 feet above the ground. The equat
Elena L [17]
For this case we have the following equation:
 h = -16t ^ (2) + 30t + 6
 We substitute the value of h = 10 in the equation:
 10 = -16t ^ (2) + 30t + 6
 Rewriting we have:
 0 = -16t ^ (2) + 30t + 6-10
 0 = - 16t ^ (2) + 30t - 4
 We look for the roots of the polynomial:
 t1 = 0.144463904
 t2 = 1.730536096
 "the ball passes its maximum height, it comes down and then goes into the hoop". Therefore, the correct root is:
 t = 1.730536096
 Answer:
 
It goes into the hoop after:
 t = 1.73 seconds

The population of algae in an
Westkost [7]

Given:

Initial population = 100 algae

Growth rate = 30% per day.

Time = 5 days

To find:

The future amount of population.

Solution:

The exponential growth model is

y=a(1+r)^t

where, a is the initial value, r is the rate of interest in percent and t is time period.

Substituting the given values, we get

y=100(1+\dfrac{30}{100})^5

y=100(1+0.30)^5

Now, solve this.

y=100(1.30)^5

y=100(3.71293)

y=371.293

Therefore, the future value is 371.293 algae.

A chi-square test for independence is used to evaluate the relationship between two variables. If both variables are classified
Len [333]

Answer:

df = (r - 1) * (c - 1)

Step-by-step explanation:

Chi square is calculated when simple random sampling is known and variable are categorical.

Four steps are included in chi-square:

(1) state the hypotheses

(2) formulate an analysis plan

(3) analyze sample data

(4) interpret results.

State the hypothesis is

null  hypothesis: Variable a and variable b are independent.

H 1: Variable a and variable bare not independent.

Formulate analysis plan:

This plan describe the significance level and test statistic.

Analyze the sample data

We analyze the degree of freedom and expected frequencies.

The degree of freedom formula is

df = (r - 1) * (c - 1)

r = number of levels for one categorical variable

c = number of levels for the other categorical variable
