For 70 people i would say ab 445
Answer:
Not true
Step-by-step explanation:
x + (2x + 5) = 3(x – 4)+7
Opening bracket on left and side and distributing 3 over (x-4) on right hand side
x+2x+5=3x-3 x 4 + 7
adding like terms
3x+5=3x-12+7
3x+5=3x-5
Hence
5 = -5
Which is not possible , Hence the equation given to us is false.
Answer:
y= 18
Step-by-step explanation:
Answer: a)
b)
c)
d) 
Step-by-step explanation:
Since f is an exponential function.
So, it is expressed as

Here f is the present value
p is the initial value
r is the rate of growth per time period
t is the time period.
(a) b represents the 1-unit growth factor for f.

(b) c represents the n n-unit growth factor for f.

(c) d represents the m m-unit growth factor for f.

Write a formula that expresses c in terms of b.
Since
Hence, a)
b)
c)
d) 
To find relative frequency of no voters;
p(A)=favourable outcomes/total outcomes
p(A)=100/400
= 1/4 or 0.25
Therefore, the probability a person will respond with a no is 0.25.
Hope I helped :)
