Answer:
204
Step-by-step explanation:
Square of 14 = 14 × 14 = 196
Cube of 2 = 2 × 2 × 2 = 8
So sum of square of 14 & cube of 2= 196 + 8 = 204
Answer:
No
Step-by-step explanation:
To estimate population proportion from a sample, we must ensure that the sample data is random. Though a simple random sample of college students from a particular college was used as the sample data. However, selection of the college should have been randomized as well, a stratified random sample would have been a better sampling method whereby certain colleges are selected based on region or other criteria and then a random sample of it's statistics students selected. The sample proportion Obtian from a sample of this nature will be more representative of the population proportion of all college statistic student.
4x+2(3-2x)=10, 4x+6-4x=10, x+6=10, x=4
8x² - 4 = 28
8x² = 28 + 4
8x² = 32
x² = 32/8
x² = 4
x = <span>±2
