Answer: a) Unimodal and symmetric
b) 0.26
c) 0.038
Step-by-step explanation:
Given: Sample size of investors (n)= 131
True proportion of smartphone users(p) =26%
a) Since sampling distribution for the sample proportion is approximately normal when n is larger.
Normal distribution is Unimodal and symmetric.
So correct option : Unimodal and symmetric
b) mean of this sampling distribution = p = 0.26
c) standard deviation of the samplingdistribution =
Y/6 - 5 = 2. First add 5 to both sides. Then multiply both sides by 6. The answer to y is 42. To check plug in 42 for y. 42/6 -5 = 2 ==> 7-5 = 2 ===> 2=2. Therefore it is correct. ANSWER: y=42.
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:
x=22
Step-by-step explanation:
Rule states diagonals = same so 6x-36 = 96 in which x=22 cause 6(22)=132
132-36 = 96
Answer:
its commutative property. you just switch the letters and they will still have the same value
