Answer:

24° and 66°

Step-by-step explanation:

Complementary angles sum to 90°

let the larger angle be x then the smaller angle is x - 42 and their sum is

x + x - 42 = 90, that is

2x - 42 = 90 ( add 42 to both sides )

2x = 132 ( divide both sides by 2 )

x = 66 and x - 42 = 66 - 42 = 24

The smaller angle is 24° and the larger angle is 66°

Sums of series, Maths. Any help appreciated.

Andrej [43]

Answer:

Step-by-step explanation:

Well, a series in math is simply the sum of the various numbers, or elements of a sequence. For example, to make a series from the sequence of the first five positive integers 1, 2, 3, 4, 5, just add them up. So, 1 + 2 + 3 + 4 + 5 = 15 is a series.

Solve for x 3x + 3 − x + (−7) > 6 A. x > (−5) B. x > 2.5 C. x > 5 D. x < 5

denpristay [2]

ANSWER

C. x>5

EXPLANATION

The given inequality is:

3x + 3 − x + (−7) > 6

Deal with the parenthesis first to obtain;

3x + 3 − x −7 > 6

Group similar terms to get:

3x − x> 6-3+7

Combine similar terms to get,

$2x \: > \: 10$

Divide both sides by 2 to obtain:

$x \: > \: 5$

The correct choice is C. x>5

Answer:

The most appropriate inference procedure for the investigation is;

a. A linear regression t-interval for the slope

Step-by-step explanation:

Given that the slope of an horizontal line is zero, we have that there is no change in the y (dependent) variable when there is a change in the x-variable, therefore, it is important to find the true relationship between the two variables, 'x', and 'y'

The confidence interval of the slope is calculated and analyzed to determine if it excludes or includes, 0, such that, if the confidence interval exclude 0, then, it is unlikely that the slope is 0, therefore, there the relationship between the variables, 'x', and 'y' is significant

Therefore, a linear regression t-interval for the slope is most appropriate.
