Answer:
14
Step-by-step explanation:
How many 1/2s are in 7? Then, write a multiplication equation and a division equation that answer the question.
Let the number of 1/2s = x
Hence:
Division Equation =
7 ÷ 1/2
Multiplication Equation =
= 7 × 2/1
= 14
There are 14 1/2s in 7
Answer:
Step-by-step explanation:
Let X be the no of defective components produced by a certain process in one day
X is Poisson with parameter = 20
Y = no of components that can be repaired
Since each component to be repaired is independent of the other Y is Binomial with p =0.60
a) 
b) P(Y = 10)= Binomial prob (15,0.6) for y =10
= 
Here no of repairables X is binomial.
c) Prob for 15 produced and 10 repairable = product of a and b
= 0.009603
Answer:
P=6x+8
A=2x^2+11x-21
Step-by-step explanation:
Perimeter:
P=2(x+7)+2(2x-3)
P=6x+8
Area:
A=(x+7)(2x-3)
A=2x^2+11x-21

<span>Question:
</span>------------------------------------<span>
3n - 7 + 2n = 8n + 11
------------------------------------
Combine like terms:
</span>------------------------------------<span>
5n - 7 = 8n + 11
</span>------------------------------------<span>
subtract 8n from both sides:
</span>------------------------------------<span>
-3n - 7 = 11
</span>------------------------------------<span>
Add 7 to both sides
</span>------------------------------------<span>
-3n = 18
</span>------------------------------------
Divide by -3 on both sides:
------------------------------------
n = -6
------------------------------------
Answer: n = -6

Final value = Initial value × (mutiplier)^n
We have;
Initial value = 9300
Multiplier = 100%+3.2% = 103.2% = 1.032
Number of quarters in a year = 4
Substitute all values into the formula, we have

rounded to two dp
