Answer:
c
Step-by-step explanation:
tye both have the same amount on each side
$0.35 is the answer yea brainly forcing me to make it at least 20 characters.
Standard form is ax+by=c where a,b, and c are integers and a is usually positive
so
first find slope
get into form y=mx+b where m is slope
so
slope between points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
points (-1,5) and (1,2)
slope is (2-5)/(1-(-1))=-3/(1+1)=-3/2
y=-3/2x+b
find b
sub a point
(1,2)
2=-3/2(1)+b
2=-3/2+b
4/2=-3/2+b
7/2=b
y=-3/2x+7/2
add 3/2 both sides
3/2x+y=7/2
times 2 both sides
3x+2y=7 is standard form
12,345,000 in word form would be <u>Twelve million, three hundred thousand and forty-five thousand. </u>
Answer:
The p value for this case would be given with this probability:
For this case since the p value is higher than the significance level of 0.01 we have enough evidence to fail to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is significantly less than 25 min.
Step-by-step explanation:
Information given
represent the sample mean
represent the population deviation
sample size
represent the value to check
represent the significance level
z would represent the statistic
represent the p value
Hypotheis to test
We want to verify if the true mean is less than 25 min, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic would be given by:
(1)
And replacing the info given we got:
The p value for this case would be given with this probability:
For this case since the p value is higher than the significance level of 0.01 we have enough evidence to fail to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is significantly less than 25 min.
