40% of the apples are not right. Since only 3/5 are right, the that would leave 2/5 to not be right. Since 2/5=40/100, then the answer is 40%. That's just the eay I remember it, hope this helps
(1, 1), 5 + 2 = 7, not that hard!
Answer:c
Step-by-step explanation:
Decide the numbers
Answer:
Slope <em>m</em> = -3
y-intercept (0, 0)
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
y = -3x
<u>Step 2: Break Function</u>
<em>Identify Parts.</em>
Slope <em>m</em> = -3
y-intercept <em>b</em> = 0
Answer:
0.0312
Step-by-step explanation:
Given :
Mean or average time, xbar = 12.25
Standard deviation, s = 3
Sample size, n = 500
The test statistic :
(x - xbar) ÷ (s/sqrt(n))
(12 - 12.25) ÷ 3/sqrt(500)
-0.25 ÷ 0.1341640
Test statistic = - 1.863
The Pvalue :
P(Z < - 1.863) = 1 - P(Z ≤ 1.863)
P(Z < - 1.863) = 0.0312
Hence, the Pvalue = 0.0312
