The study investigated the effect of scratch programming language on students’ academic achievement and interest in probability content of mathematics curriculum. A total of two hundred and eighty-nine (289) senior secondary class two (SSII) mathematics students were involved in the study. Three research questions and hypotheses guided the study. The study employed non-equivalent pretest, post-test control group design. A researcher’s developed Probability Achievement Test (PAT) and Probability Interest Inventory (PII) was used for the study. Data collected were analyzed using mean scores, standard deviation and analysis of co-variance (ANCOVA). Findings from the study shows that students who were taught probability using scratch programming language achieved higher than those taught with conventional approach. The use of scratch programming language favored both male and female students. Finally, the use of scratch programming language increases the interest of students in probability. It was recommended that the use of scratch programming language should be incorporated into the mathematics curriculum and its use be encouraged at all level.

The Burgers-Fisher equation is a non linear partial differential equation that models various phenomena for example fluid dynamics, gas dynamics, heat transfers and etc. In this paper, we presented wavelet based Lifting schemes for the numerical solution of Burgers-Fisher equations using orthogonal and biorthogonal wavelet filter coefficients. The numerical results obtained by this scheme are compared with the exact solution to demonstrate the accuracy and also speeds up convergence in lesser computational time as compared with existing scheme. Some test problems are presented for the applicability and validity of the scheme.

In this work, we focus on the nonlinear p(x)-triharmonic equation without a source term with variable exponents 𝑧𝑡𝑡 − ∆𝑝(𝑥) 3 𝑧 + |𝑧𝑡 | 𝑞(𝑥)−2 𝑧𝑡 = 0. By utilizing by Komornik's lemma, we prove the asymptotic behaviour for the solution under suitable conditions on the variable exponents.

This research investigated and compared regression models to determine if there was equality between federal government capital expenditure and economic growth from 1981 to 2022. This research utilized secondary data obtained from the National Bureau of Statistics and Federal Ministry of Finance, Office of the Accountant General of the Federation, and also utilized multiple regression models to analyze the data. The Durbin method was utilized to identify the important variables in a multiple regression model, and a test was conducted to assess if the models were equal; this revealed that all the models’ parameters estimate were significant at 5% except constant parameter, which seem biased. It was discovered that the most suitable model among the three regression models (Stratocracy, Bureaucracy and Pooled) was the Pooled Model, which has the highest R2 value with 100%, have the smallest HQC value of -408.150 and the highest F-value of 79773673382 respectively.

We consider the problem of finding a pair of functions 𝑝(𝑥) and 𝑤(𝑥,𝑡) that satisfy the equation 𝑤𝑡𝑡(𝑥,𝑡) = 𝑤𝑥𝑥(𝑥,𝑡) + 𝑓(𝑡)𝑝(𝑥) under Cauchy boundary conditions. We will see that an approximate solution can be found using the techniques of generalized inverse problem of moments and find dimensions for the error of the estimated solution.

Malthusian, Verhulst and Richards Growth Models are widely used population growth models. However, in this article, we simulate the future population growth of Federal Capital Territory (F.C.T) using three models: exponential, logistic and Richards; to ascertain the model that has the best fit in modelling population growth of FCT over time. This study is based on the assumption that population growth follows a sigmoid curve that shows the rate of population growth slowing down as the population approaches a certain limit or carrying capacity. Then, a comparative analysis of exponential, logistic and Richards methods is presented. Furthermore, the result of the analysis shows that FCT has a growing population and that Richards growth model with MAPE and RMSE values of 1.39% and 19159.53826 respectively is the most accurate and closely followed by logistic growth model with values 3.18% and63451.47975 respectively. The study concludes that Richards growth model with R squared value of 0.786 has the best fit for population growth projection of FCT. With approximate growth rate at 9.3% per annum, the projected population of the FCT will hit 31,635,270 million by the year 2045 all things being equal. Therefore, the government should invest in massive agricultural revolution to accommodate the growing population.

The work presented the impact of some Foreign Macroeconomic Indicators on the Gross Domestic Product of Nigeria using linear regression method. The study employed linear regression approach with Gross National Product (GNP) and Foreign Domestic Product (FDI) as the predictors while the Gross Domestic Product (GDP) was the response variable. The parameters of the model are estimated alongside the coefficient of determination (R2 ), and its adjusted (R2 adj), variance inflation factor (VIF), P-values and Tvalues were also estimated. This paper revealed the level of significant contributions of both the Foreign Direct Investment (FDI) and the Gross National Product (GNP) to the Gross Domestic Product (GDP) of Nigeria Economy. The research revealed that imports of goods and services had a large positive impact on Nigeria's GDP, whereas other explanatory factors have a significant negative impact on GDP. Based on this finding, it is proposed that local products be improved so that Nigerian-made goods/products may compete well with imported goods and services, hence lowering importation naturally rather than forcibly.
