Answer:
c = 77
b = 77
Step-by-step explanation:
c and b are equal because they are vertically opposite.
In addition, they both form a supplementary pair with 103 (but not at the same time).
c + 103 = 180 c and 103 form a supplementary pair.
c = 180 - 103
c = 77
c = b = 77

Answer:
Step-by-step explanation:
The formula for determining the confidence interval for the difference of two population means is expressed as
z = (x1 - x2) ± √(s²/n1 + s2²/n2)
Where
x1 = sample mean of group 1
x2 = sample mean of group 2
s1 = sample standard deviation for data 1
s2 = sample standard deviation for data 2
For a 95% confidence interval, the z score is 1.96
From the information given,
x1 = 25 pounds
s1 = 9 pounds
n1 = 78
x2 = 14 pounds
s2 = 7 pounds
n2 = 43
x1 - x2 = 25 - 14 = 11
√(s²/n1 + s2²/n2) = √(9²/78 + 7²/43) = √1.038 + 1.1395)
= 1.48
The upper boundary for the confidence interval is
11 + 1.48 = 12.48 pounds
The lower boundary for the confidence interval is
11 - 1.48 = 9.52 pounds
For the eradication of malignancies like the aggressive type of human brain tumour known as glioblastoma multiforme (GBM), 3D platforms are crucial for tracking tumour growth and assessing treatment candidates.
<h3>What is Glioblastoma Multiforme (GBM)?</h3>
Glioblastoma (GBM), commonly known as a grade IV astrocytoma, is an aggressive brain tumour that grows quickly. The local brain tissue gets invaded, but it typically does not spread to distant organs. GBMs can develop from lower-grade astrocytomas or develop from new brain tumours.
Some characteristics of GBM are-
- We explore cellular behavior, expression profiles of malignancy, and apoptosis-related genes within this novel network using suspension and spheroid-based models of GBM.
- In-depth research is also done on the sensitivity to the anticancer medication Digitoxigenin.
- According to the research, GelMA hydrogels contain high levels of prosurvival Bcl-2 gene expression and sparse or spheroid U373 cells, which have much lower expressions of apoptosis-activating genes like Bad, Puma, and Caspase-3.
- The up regulation of matrix-metalloproteinase genes within GelMA suggests that gels have a beneficial effect on the extracellular remodelling of cancer cells.
- Through the investigation of 3D malignant cancer cell behavior, this special photo curable gelatin shows significant promise for the practical translation of cancer research and, consequently, for more effective treatment techniques for GBM.
