In order to check for regional bias in a widely used standardized test, researchers checked for a difference in the means of random samples of scores from two regions. the sample mean of the 110 scores from region 1 was 497 with standard deviation 112. the sample mean of the 100 scores from region 2 was 511 with standard deviation 114. let μ1 be the population mean score from region 1, and let μ2 be the population mean score from region 2. the researchers assumed the population standard deviations are equal and used the alternative hypothesis ha: μ1−μ2≠0. if the test statistic is t≈−0.90 and the number of degrees of freedom is 208, what is the p-value for this hypothesis test?

7

step-by-step explanation:

the answer would be 7

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
