Answer:
- parth
- anna
- elaina
- ben
- jack
Step-by-step explanation:
- so, ben votes= 20+x [from the statement : Ben received 20 more votes than Jack]
[ben got 40 less than anna. so, anna's votes -40 = ben's votes = 20+x.
so, anna's votes =60+x ( addind 40 on both sides)]
- elaina = 50+x[from the statement:Elaina received 50 votes more than jack]
- parth=70+x [ as elaina got 20 less than parth, parth's votes -20=50+x.so, part's votes=70+x]
- as x is obviously positive, now we can rank them as shown(most to least) :
- parth
- anna
- elaina
- ben
- jack
Answer: the answer is C because it is the only one that matches with one pair on the table wich is (4,2)
The value of x is -0.01.
<h2>Linear system</h2>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
<h3>Simplification</h3>
Simplification is to make something easier to do or understand and to make something less complicated.
Given
The equation is 102x + 11 = (x + 6)2 – 2.
<h3>To find </h3>
The value of x.
<h3>How to find the value of x?</h3>
The equation is 102x + 11 = (x + 6)2 – 2.
On simplifying,
102x + 11 = 2(x + 6) - 2
102x + 11 = 2x + 12 - 2
102x + 11 = 2x + 10
102x - 2x = 10 - 11
100x = -1
x = -0.01
Thus, the value of x is -0.01.

Answer:
I think the answer is repeating because it'd be
0.55
Answer: 0.9192433
Step-by-step explanation:
Given : A nationwide study of American homeowners revealed that 65% have one or more lawn mowers.
i.e. Population proportion :
A lawn equipment manufacturer, located in Omaha, feels the estimate is too low for households in Omaha.
Then, his hypothesis will be :-
Since, the alternative hypothesis is left tailed , so the test is a left-tailed test.
Sample size : n= 497
The sample proportion of people ad one or more lawn mowers=
Test statistic for proportion :-
i.e.
Now, by using the standard normal table for z , we have
P-value (left tailed) =
