answer:

explanation:
the area of the larger square is 36 (6*6), and the area of the smaller square is 16 (4*4). to find the ratio of the area, simply just put 16 over 36 and simplify.

Answer:
Step-by-step explanation:
The slope of line u is 9/2; the line perpendicular to that is the opposite reciprocal...opposite sign and the flip of the fraction. The perpendicular slope is -2/9
Answer:
(5h-4t)(5h+4t)
Step-by-step explanation:
25h² - 16t²
adding and subtracting 20ht from it (√25 and √16 = 5x4 = 20):
25h² + 20ht - 20ht -16t²
factor:
(5h-4t)(5h+4t)
Answer:
first put the numbers on the lines then plot the points that are given
Step-by-step explanation:
first with the numbers of the line then plot the points that are given and you will find the slope and y-intercept of the equation
Answer:
The test statistics is 
Step-by-step explanation:
From the question we are told that
The data given is
330 620 1870 2410 4620 6396 7822 81028309 12882 14419 16092 18384 20916 23812 25814
The population mean is 
The sample size is n = 16
The null hypothesis is 
The alternative hypothesis is 
The sample mean is mathematically evaluated as

So

=> 
The standard deviation is mathematically represented as

So



=> 
Generally the test statistic is mathematically represented as


From the z-table the p-value is

From the values obtained we see that
so we fail to reject the null hypothesis
Which implies that the claim of the NarStor is wrong
