Answer:
19.57
Step-by-step explanation:
100% of 19 is 19.
In order to find out what 1% of 19, move the decimal point two place to the left. 1% of 19= 0.19. To find 3% of 19, multiply .19 x 3. add 0.19 x 3 to 19, aka add 0.57 to 19 to get 19.57= 103% of 19
We can find a and b using inverse trig functions,
Hope this helps.
The "x" intercept is found when you plug in "0" for "y"
-6x + 3(0) = 18.9
-6x = 18.9 (Divide both sides by -6)
x = - 3.15
(-3.15, 0) is your x-intercept
Now plug in "0" for the x
-6(0) + 3y = 18.9
3y = 18.9 (Divide both sides by 3)
y = 6.3
(0, 6.3) is your y - intercept
In order to find the slope of line that passes through 2 points, use the equation slope=rise/run
rise = 5-(-4) =9
run = 2- 0 =2
slope = rise/run = 9/2
Answer:
106.34%
Step-by-step explanation:
hay 24 personas en total (11 mujeres+13 hombres)
la probabilidad para que uno de los alumnos es un hombre es 13/24 (porque hay 13 hombres en la clase)
Entonces, si uno hombre está elegido, quedan 12 hombres, así que, la probabilidad si es un hombre es 12/23 (porque una persona ya está elegido y quedan 23 personas)
la probabilidad es 13/24+12/23=587/552=106.34% (Redondeado a la décima más cercana)
