Answer:
Step-by-step explanation:
to go from (4, 3/4 ) to (6, 0) you need
a line with slope m= (y2-y1)/(x2-x1) = -0 / 4-6 =
use the quation of a line point-slope
(y-y1)=m(x-x1)
substitute m= -3/8 and (x1,y1) with (6,0)
Now does point (10,4) where is the aim is verified by this equation?
substitute x=10, y=4 in the equation to check
4= -3(10-6)/8
4= -3*4/8
4=-3/2 this is never true so you do NOT make the shot
Answer:
x = 6.3375
Step-by-step explanation:
sin53 = 4/5 (roughly) = 5.07/x
=> 4x = 25.35
=> x = 6.3375
Answer:
Yes
Step-by-step explanation:
We can test this claim using the one proportion z test :
x = 25 ; n = 100
Phat = x / n = 25 / 100 = 0.25
H0 : P = 0.15
H0 : P > 0.15
The test statistic :
Z = (phat - p) ÷ √p(1-p)/n
Z = (0.25-0.15) ÷ √(0.15*0.85)/100
Z = 2.8
Using the Pvalue from Zscore calculator :
α = 0.05
Pvalue (Z < 2.8) =0.0026
Pvalue < α ; We reject the Null
