The probability of scoring exactly four out of the given six shots is 0.311, calculated using the concept of binomial distribution in probability theory.
What is a Binomial Distribution?
Binomial Distribution in probability theory is defined as getting x number of successes on repetition of trial n times, the formula for binomial distribution is C(n,r) × (p)x × (q)n - r, where p denotes the probability of success and q denotes the probability of failure.
Calculation of the probability of scoring exactly four shots out of six
Let p denote the probability of success and q denote the probability of failure, which is equal to 1 - p.
Using Binomial Distribution, we get,
P(x = r) = C(n,x) × (p)x × (q)n - x
Taking r = 4,
P(x = 4) = C(6,4) × (0.6)4 × (0.4)2
= 6! / (4! 2!) × (0.6)4 × 0.16
= 0.31104
~ 0.311
Hence, the required probability using binomial distribution is 0.311.

If I want to buy 3 packages of 10 cans it will cost me around $1.4 per can.
It is given that the price of a package of 10 cans of soup = $14
and the price of an individual can = $2
Now, if I want to purchase at least 25 individual cans there can be two possible ways to do this:
I Purchase 2 packages of the can and then purchase the rest individual cans. Thus, if I have to purchase 25 cans it will cost around: 14 × 2 + 5 × 2 = $38.I Purchase 3 packages of cans. It will cost me around: 3 × 14 = $42. Also, it will give me extra 5 cans.Therefore, if I decided to buy 3 packages of 10 cans it will cost me $42 and I will pay $1.4 for each can.

Find the partial sum sn of the geometric sequence that satisfies the given conditions. a3 = 36, a6 = 288, n = 5
The value of the partial sum of geometric sequence with terms a3 = 36 and a6 = 288 is given by 297. This is obtained by using the concept of partial sum of a geometric progression.
What is geometric progression?
Geometric progression is defined as a series of numbers having a fixed ratio between each term and its preceding term. It is also known as a geometric sequence or G.P., and is exemplified as a1, a2, a3, ….., an
Here, the first term is denoted by a1 and its common ratio is shown by r, which is calculated using the formula a2 by a1. The partial sum of a G.P. is given by a1 ( rn - 1 ) / ( r - 1 ), when r > 1 and a1 ( 1 - rn ) / ( 1 - r ), when r < 1
Calculation of the partial sum of the geometric sequence that satisfies the given conditions. a3 = 36, a6 = 288, n = 5
Given:
Value of a3 = 36
Value of a6 = 288
n = 5
a3 = ar2 — 1
a6 = ar5
Now, a6 / a3 = ar5 / ar2 = 288 / 36
r3 = 8
Taking cube root both sides, we get,
r = 2
Putting the value of r in equation 1,
a3 = a(2)2
36 = 4a
a = 9
As r > 1, using the formula for Sn as a(rn - 1) / (r - 1)
Sn = 9(2n - 1) / (2 - 1)
Sn = 9(2n - 1)
Using n = 5, we have,
Sn = 9[(2)5 - 1]
Sn = 9(32 - 1)
Sn = 9 × 33
Sn = 297
Hence, the value of the partial sum of a G.P. is 297

Solve the following system of equations.
5 a-b=17
3 a+2 b=5
Answer:
a = 3 , b = - 2
Step-by-step explanation:
5a + b = 17 → (1)
3a + 2b = 5 → (2)
multiplying (1) by 2 and adding to (2) will eliminate b
10a + 2b = 34 → (3)
add (2) and (3) term by term to eliminate b
13a + 0 = 39
13a = 39 ( divide both sides by 13 )
a = 3
substitute a = 3 into either of the 2 equations and solve for b
substituting into (1)
5(3) + b = 17
15 - b = 17 ( subtract 15 from both sides )
- b = 2 ( multiply both sides by - 1 )
b = - 2
then solution is a = 3 , b = - 2

Stanley bought 16 bags of white rice and 7 bags of brown rice. each bag of rice weighed 13 kilograms. he also bought 17 bags of potatoes. how many kilograms of rice did stanley buy in all?
Stanley bought total 299 kilograms of rice.
To find the amount of rice in kilograms, bought by Stanley, we will perform multiplication and addition.
Weight of 1 bag = 13 kilograms
Weight of white rice = 16 × 13
Performing multiplication to calculate the weight
Weight of white rice = 208 kilograms
Weight of brown rice = 7 × 13
Performing multiplication to calculate the weight
Weight of white rice = 91 kilograms
Total amount of rice bought by Stanley = 208 + 91
Performing addition to calculate the weight
Total amount of rice bought by Stanley = 299 kilograms
Hence, Stanley bought total 299 kilograms of rice.

the degree of correlation among independent variables in a regression model is called . a. multicollinearity b. the coefficient of determination c. interaction d. the sum of squared errors (sse)
Multicollinearity refers to the degree of correlation among independent variables in a regression model.
What is Multicollinearity?In a multiple regression model, one predictor variable can be predicted linearly from the others using a high degree of accuracy when there is a phenomenon known as multicollinearity (also known as collinearity). In this case, minor adjustments to the model or the data may cause the multiple regression's coefficient estimates to fluctuate unpredictably. Multicollinearity only impacts calculations pertaining to specific predictors; it has no impact on the predictive capability or reliability of the model as a whole, at least within the sample data set. In other words, a multivariate regression model with collinear predictors can show how well the complete set of predictors predicts the outcome variable, but it could not provide accurate information about any particular predictor or which predictors are redundant in relation to others.

We wish to test the hypothesis that the mean weight of a population of fish is 140g. With sigma=15 g and alpha= 0.05, and a sample of 36 fish, find a) the mean values which would lead to a rejection of the hypothesis and Use a two-tailed test.
Using the z-distribution, it is found that mean weights less than 135.1g and more than 144.9 would lead to a rejection of the hypothesis.
What is the critical value of the test?We have a two-tailed test, with a significance value of α = 0.05, hence, using a z-distribution calculator, the critical value is given by:
|z| = 1.96 -> z < -1.96 or z > 1.96.
What is the test statistic?The test statistic is given as follows:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which:
X is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.[tex]\sigma[/tex] is the standard deviation of the population.n is the sample size.For this problem, the parameters are given as follows:
[tex]\mu = 140, \sigma = 15, n = 36[/tex]
The lower bound of acception is found as X when z = -1.96, hence:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
-1.96 = (X - 140)/(15/6)
-1.96 = (X - 140)/(2.5)
X - 140 = -1.96 x 2.5
X = 135.1.
The upper bound of acception is found as X when z = 1.96, hence:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
1.96 = (X - 140)/(15/6)
1.96 = (X - 140)/(2.5)
X - 140 = 1.96 x 2.5
X = 144.9.
Hence:
Mean weights less than 135.1g and more than 144.9 would lead to a rejection of the hypothesis.
