Answer:
7
Step-by-step explanation:
7+2= 9
16-9=7
First add 90 to both sides) -mk>85+90simplify 85+90 to 175) -mk>175divide both sides by K) -m>175/kmultiply both sides by -1) m<-175/k
YOUR ANSWER IS
M<-175/K

Answer:
<em>C. 94</em>
Step-by-step explanation:
Take in account for PEMDAS: Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.
First is to find the answer within the innermost parenthesis:
(4²+1).
Find the exponent of 4², which is 16, leaving you the equation of
16+1, which equals to 17.
Next you multiply 3 by 17 (since the parenthesis of 17 borders 3):
17×3=51.
Next, multiply 51 by 2 (same rule as 3×17).
51×2=102.
After this you get 102-2³. Now, find 2³=2×2×2=8
This gets you to 102-8, ending up with your answer of 94.
Answer:
The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.
P(6.8 ≤X≤9.3) = 0.5932
Step-by-step explanation:
Step 1:-
by using normal distribution find the areas of given x₁ and x₂
Given The average watermelon weighs 8 lbs
μ = 8
standard deviation σ = 1.5
I) when x₁ = 6.8lbs and μ = 8 and σ = 1.5
ii) when x₂ = 9.3 lbs and μ = 8 and σ = 1.5
<u>Step2</u>:-
The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.
P(6.8 ≤X≤9.3) = A(z₂) - A(-z₁)
= A(0.866) - A(-0.8)
= A(0.866)+ A(0.8)
check below normal table
= 0.3051 + 0.2881
= 0.5932
<u>Conclusion</u>:-
The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.
P(6.8 ≤X≤9.3) = 0.5932
Answer:
The tree was 40 in tall when planted
The tree's growth rate is 10in per year
Ten years after Planting, it is 140 inches tall
Step-by-step explanation:
original(slope intercept form) : y = 10x + 40
y = 10(10) + 40
y = 100 + 40
y = 40
