Positive numbers are always greater than negative numbers.
Therefore 2 > -13. In words, 2 is greater than -13.
Answer:
y=-4x-2
Step-by-step explanation:
linear function, y = mx+c
the y intercept of the graph,c, is -2
thus y = mx - 2
substitute a point on the graph into the equation, (2,-1)
2 = m(-1) -2
m = - 4
thus equation of graph is y = -4x-2
She needs to earn at least 84 to buy the mp3 player
earnings=earningsperhour times numberofhoursworked
earnings per hour=12 dollars
number of hoursworked=h
therefor
earnings=12 ties h or12h
earnings is at least 84
earnings is greater than or equal to 84
earnings<u>></u>84
12h<u>></u>84
solve
12h<u>></u>84
divide both sides by 12
h<u>></u>7
she needs to work at least 7 hours
to graph, draw a line at x=0 and shade to the right, make the line solid
Answer:

is correct</h3><h3>
The alternate hypothesis for the significance test is </h3>
Step-by-step explanation:
The alternate hypothesis use the sumbol for the population value
Let p be the proportion , Mean be 
and stadard deviation be 
The null hypothesis states that population value is equal to the value mentioned in the given claim.
(by given).
The alternate hypothesis for the significance test states that the opposite of the null hypothesis(based on the claim )
∴
The symbol "<" because we want to test if the maze is completed faster and thus if the time has decreased.
<h3>∴ option c)
is correct.</h3>
Based on the sample results of the population the percentage of population that prefers reading a hard copy i fht e digital copy is 4, the hard copy is 21 and n equas 25 is 84%
Step-by-step explanation:
From the above question we know that .
<u>Total number of population, n = 25</u>
Number of people who prefer to read a digital copy = 4
Number of people who prefer to read a hard copy = 21
As per the question we need to find out the percentage of population who prefer to read hard copy.
So we use the formula
<u>Percent of population preferring hard copy = Hard copy/Total*100</u>
<u></u>
Percent of population that prefers hard copy = 21/25*100
Percent of population that prefers hard copy = 0.84 × 100 = 84%
<u>So , the percent of population who prefers to read a hard copy are about 84%.</u>
<u></u>
