All you wanna do is divide-
490/3 1/2= 140
they make 140 buttons per hour
You plug in 2x + 4 into the y for the other equation (3x +y ) and solve for it
You take the number of the colored pencils and divides it with the people in the class.
350/14 = 25
Answer:
Test statistic = -2.44
There is enough evidence to support the strategist's claim.
Step-by-step explanation:
H0 : p = 0.41
H1 : p < 0.41
pˆ = 0.38
Test statistic :
z=pˆ−p/√p(1−p)/n
Z = (0.38 - 0.41) / √(0.41(1 - 0.41) / 1600
Z = - 0.03 / √0.0001511875
Z = - 0.03 / 0.0122958
Z = - 2.4399
Test statistic = -2.44
The Pvalue :
P(Z < -2.44) = 0.0073436
α - level = 0.02
If Pvalue < α ; Reject H0
0.0073436 < 0.02 ; We reject H0
Since Pvalue < α ; Hence, There is enough evidence to support the strategist's claim.
Answer:
548
Step-by-step explanation:
1) Divide 137 by 0.25 (25%)
137/0.25 = 548.
To check, find 25% of 548.
(548 x 25)/100 = 137
