Answer:
(0.1392,0.1466)
Step-by-step explanation:
Given that a survey given to consumers leaving a supermarket three days before Thanksgiving asked whether turkey would be part of the Thanksgiving meal
People surveyed = 182
claimed not eating turkey = 26
Sample proportion = 
Std error =
Margin of error = 1.96*SE=
Confidence interval = 
To complete the identity, we need these fundamental identities:



Thus, by identity 1 we have:

by identity :

recall the values :


,
so:

Putting all these together, we have:

which is equal to

, by identity 3
Answer: D
This is a parabola which looks like an inverted U. Its will have a maximum value when t = 7 as we see from the vertex form below:-
- t^2 + 14t - 40
= - ( t - 7)^2 + 49 - 40
= -(t - 7)^2 + 9
There is an axis of symmetry at x = 7.
so a is true since 7 is the maximum value of the function and its less at t = 6.
c is also true because of the symmetry about t = 7
Answer:
a) P = 5000(1.014)^y
b) 5,908
Step-by-step explanation:
Here, we want to write an exponential growth model;
a)The model will be represented as;
P = 5000( 1.014)^y
where P is the population at a particular year after 2010
y is the number of years after 2010
b.) For 2022;
y = 2022-2010 = 12
P = 5000(1.014)^12
P = 5,908 approximately
A
7*(1)(14) = 98 Not the right answer. I have done what is inside the brackets first. (5 - 4) = 1; (5 + 9)= 14; 7 * 1 * 14 = 98 which is not 6
B
7 * [1 * 5] + 9 = 44; 7 * 5 + 9 = 35 + 9 = 44 Also not 6
C
7*[5 - 20 + 9] = - 42; Not 6 as well 7*[14-20] = 7*-6 = - 42
D
7*5 - [20 + 9] = 35 - 29 = 6
Answer D
