In triangle STU the measure of angle U ie 90°. TU=6.6 US=2.3 find the measure of angle S
Mazyrski [523]

Answer:

70.8 to one decimal place,

or to be exact : 70.7873

Step-by-step explanation:

In right angle triangles, trigonometry functions can be used

here tan out of sin, cos ,tan seems the most appropriate

tan(x) = opposite/adjacent

tan(x) = 6.6/2.3

x = tan^-1 (6.6/2.3)

x = 70.7873

Which statement best describes the association between variable X and variable Y?
Maksim231197 [3]

Answer:

Perfect positive association

Step-by-step explanation:

Definition: A perfect positive association means that a relationship appears to exist between two variables, and that relationship is positive 100% of the time. Two variables have a positive association when the values of one variable tend to increase as the values of the other variable increase. (+1 indicates a perfect positive linear relationship)

Definition: A perfect negative association means that a relationship appears to exist between two variables, and that relationship is negative 100% of the time. Two variables have negative association when the values of one variable tend to decrease as the values of the other variable increase. (-1 indicates a perfect negative linear relationship)

Values between 0.3 and 0.7 (-0.3 and -0.7) indicate a moderate positive (negative) linear relationship.

From the graph we can see that this relationship shows perfect positive association (both variables increase and we can plot the straight line which will include all points)

What is the slope of the line that passes through the points (48, 10) and (-36, 17)?
schepotkina [342]

Answer:

y = m x + b      equation of a straight line

m = (y2 - y1) / (x2 - x1)     slope of line

m = (17 - 10) / (-36 - 48) = 7 / -84 = -1 / 12

y = -x / 12 + b     equation of line

Or b = y + x / 12

If y =  10 and x = 48 then    b = 10 + 48 / 4 = 14

if  y = 17 and x = -36 then b = 17 - 36 / 12 = 14

So b = 14 and   y = -x / 12 + 14

Carmen worked more than 40 hours last week and earned $352.95. Her regular hourly pay rate is $7.80. After 40 hours, she is paid
posledela

She worked 50.5 hours last week.

7.80x40=312

352.95-312=40.95

40.95/4.90=10.5

10.5+40=50.5

3x + 4 = 8x – 11 does anyone know how to do this ​
Nataly [62]

Answer:

x = 3

Step-by-step explanation:

Subtract 8x from both sides.

3x+4−8x=8x−11−8x

−5x+4=−11

Subtract 4 from both sides.

−5x+4−4=−11−4

−5x=−15

Divide both sides by -5.

−5x

−5

=

−15

−5

x=3
