The figure below shows the standard normal distribution or "bell-shaped" curve, plotted against the z-score.
The z-score is defined as
z = (x - μ)/σ
where
x = nrandom variable
μ = mean
σ = standard deviation.
As z-values decrease, areas to the left of z decrease as shown by the shaded area.
Answer:
Areas to the left of z decrease.
Answer:
C
Step-by-step explanation:
The rule of an 180⁰ degree rotation is:
(x,y) -> (-x,-y)
Of all the rules of rotation, this is the only one that fits.
Answer:
A
Step-by-step explanation:
m angle b equals 59 now we have to find the arc of angle b.
so use the equation arc AC = 2(59)
arcAC = 118
360 - 118
=242
121/2
= 60.5
Answer: 3.3 × 10⁹
Concept:
When multiplying exponents, add the exponents together.
When dividing exponents, subtract the exponents.
Solve:
<u>Given expression</u>

Hello,
c1=10.9 (in) A1=392.4 (in²)
c2=21.8 (cm) =21.8/2.54 (in)
k=c2/c1=(21.8/(2.54*10.9)=2/2.54
A2=(2/2.54)²*392.4=243,28848...≈243.29 (in²)
