Answer:

68 degrees

Step-by-step explanation:

The straight horizontal line is a straight angle with 180 degrees it is split in a way that you know under the right angle, is another right ange making up part of the 180° line, add 22 and then subtract what you get from 180 to get 68.

A simpler way, add the angles in the X and 22 degree things and there is a right angle, 90 degrees, subtract 22 from 90 and get 68

Two different ways, either will work

Hope this helps!

Musya8 [376]

Answer:

a) P(NP/L) = 0.1

b) P(P/L) = 0.9

c) P(P) = 0.666

d) P(L/P) = 0.945

e) P(NL U NP) = 0.37

Step-by-step explanation:

given that;

P = passing the course, NP = Not passing the course, L = Using lab, NL = not using Lab

P(L) = 70% = 0.7, P(NL) = 30% = 0.3

P(P/L) = 90% = 0.9

P(P/NL) = 12% = 0.12

the probability of not passing the course given that the student went to the Learning Lab

P(NP/L) = 1 - P(P/L)

P(NP/L) = 1 - 0.9

P(NP/L) = 0.1

the probability of using the Learning Lab and passing the course

P(P/L) = 0.9

the probability of passing the class

P(P) = P(P/L) * P(L) + P(P/NL) * P(NL)

= (0.9 * 0.7) + (0.12 * 0.3)

P(P) = 0.666

the probability that a student utilized the Learning Lab given the condition that the student passed the class

P(L/P) = [P(P/L) * P(L)] / P(P)

P(L/P) = (0.9 * 0.7) / 0.666 = 0.63/0.666

P(L/P) = 0.945

the probability of not using the Learning Lab or not passing the class

P(NL U NP) = P(NL) + P(NP) - P(NP n NL)

= 0.3 + 0.334 - (0.88 * 0.3 )

= 0.634 - 0.264

P(NL U NP) = 0.37

Use the equation m Subscript PQ Baseline equals StartFraction f left parenthesis x 1 plus h right parenthesis minus f left paren

babunello [35]

Answer:

m = 12

Step-by-step explanation:

For f(x) = 2x² you want to find the slope m using ...

m = (f(x+h) -f(x))/h

at x=3.

Filling in the function definition and its arguments, we have ...

m = (2(x+h)² -2x²)/h = (2x² +4hx +2h² -2x²)/h = 4x +2h

The value of this as h goes to zero is ...

m = 4x

At x=3, the slope is ...

m = 4·3 = 12

_____

The attached graph shows a numerical estimate of the slope (f'(3)=12) and the line with that slope through the point P(3, 18). The line certainly appears to be tangent to the curve at that point.
