Answer:
p ( x > 2746 ) = p ( z > - 1.4552 )
= 1 - 0.072806
= 0.9272
This shows that there is > 92% of a republican candidate winning the election hence I will advice Gallup to declare the Republican candidate winner
Step-by-step explanation:
Given data:
51% of male voters preferred a Republican candidate
sample size = 5490
To win the vote one needs ≈ 2746 votes
In order to advice Gallup appropriately lets consider this as a binomial distribution
n = 5490
p = 0.51
q = 1 - 0.51 = 0.49
Hence 
> 5 while 
< 5
we will consider it as a normal distribution
From the question :
number of male voters who prefer republican candidate ( mean ) ( u )
= 0.51 * 5490 = 2799.9
std = 
= 
= 37.0399 ---- ( 1 )
determine the Z-score = (x - u ) / std ---- ( 2 )
x = 2746 , u = 2799.9 , std = 37.0399
hence Z - score = - 1.4552
hence
p ( x > 2746 ) = p ( z > - 1.4552 )
= 1 - 0.072806
= 0.9272
This shows that there is > 92% of a republican candidate winning the election hence I will advice Gallup to declare the Republican candidate winner
Answer:
In the expression of 7xy, if x is negative, then y must also be negative for the product to be positive.
Let me know if this helps!
Answer:
Rational
Step-by-step explanation:
okay so a natural number is anything like 1,2,3,4...etc.
a whole number is like a natural number but includes 0's
an integer is numbers that can have both positive and negative numbers
but keep in mind all of these are whole numbers or can be made into a whole number (not including natural numbers)
this leaves...
Rational
now here is a word of advice every mixed number and fraction is rational because its already in a solved and complete form but a decimal that could be solved like 0.77777 or 0.345 with a line over it or 64 squared
Irrational
a number that has no end and cant be solved like 0.86866968..... or 38 squared
Answer: B.) <em>The cost of a pizza with no toppings is $6 </em>
Step-by-step explanation:
<em>The y-intercept shown on the graph is (0,6)</em>
<em>Meaning with 0 toppings, the pizza cost </em><em>$6</em>
