Answer:
11
Step-by-step explanation:
duh add 1 and 1 merge it together to get 11
53). 100 servings / 20 people = (100/20) (svngs/ppl)
= 5 servings per person.
Each person gets 1/20 = 5% = 0.05 of the pan.
54). 100 servings / 40 people = (100/40) (svngs/ppl)
= 2.5 servings per person.
Each person gets 1/40 = 2.5% = 0.025 of the pan.
55). 100 servings / 30 people = (100/30) (svngs/ppl)
= (3 and 1/3) servings per person.
Each person gets 1/30 = (3 and 1/3) % = 0.0333... of the pan.
Answer:
C
Step-by-step explanation:
The problen asks for 5 more than two times n. 2 times n suggests multiplication. So we start out with 2n. When it says 5 more it suggests addition. So we end up with 2n+5
Answer:
x=7
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
x+30−4x=4x+9−4x
−3x+30=9
Step 2: Subtract 30 from both sides.
−3x+30−30=9−30
−3x=−21
Step 3: Divide both sides by -3.
−3x
−3
=
−21
−3
<u><em>The sides of a rhombus are all congruent (the same length.)</em></u>
Answer:
option B
Step-by-step explanation:
![P(x =x) [{\frac{1}{6} ;x =1,2,3...6]](https://tex.z-dn.net/?f=P%28x%20%3Dx%29%20%5B%7B%5Cfrac%7B1%7D%7B6%7D%20%3Bx%20%3D1%2C2%2C3...6%5D)
Given random experiment of tossing of 6 sided dice is follow above distribution
Therefore, suppose x₁, x₂ ...x₁₀ are 10 independent and indentical random variable which represent first 10 rolls
Average of first 10 rows equals
now suppose ,
x₁₁,x₁₂, ...x₁₅ are 5 independent and identical random variable which represent last 5 roll
average of last 5 roll is
Therefore,
3.5 - 3.5 = 0
