Answer:
(-14,0)
Step-by-step explanation:
lets find the equation of the line first
so lets take two points (-74,18) and (-54,12)
so slope is rise/run= -6/ 20 or -3/10
plugging into the equation
y= mx+b
we get
12= 5.4*3+b
12= 16.2+b
b= -4.2
so equation is y= -.3x-4.2
simplyfying we get
10y= -3x-42
3x= -10y-42
x= -10y-14
so we see that the x intercept is (-14,0)

Answer:
The value of 27, because it’s greater than 26.7 and less than 29.3.
Step-by-step explanation:
You should find the confidence Interval at 95%
The formula to apply is;
C.I= x±z*δ/√n
where C.I is the confidence interval, x is the mean of the sample, z is the z* value from the standard normal distribution for 95% confidence interval, δ is the standard deviation and n is the sample size
Substitute values in the formula
Find δ/√n
Calculate z*δ/√n
C.I= 28±1.2652
Upper limit is = 28+1.2652=29.2625
Lower limit is =28-1.2652=26.7348
Solution
The value 27 is within 95% confidence interval because it is greater than 26.7 and less than 29.3
Answer: 11.3 minutes
Step-by-step explanation: <u>Exponential</u> <u>Distribution</u> is a distribution with function of the form:
often related to an amount of time until an event occur.
The greek letter λ is decay parameter and have a relationship with the mean:
and x is the amount of time
Probability in exponential distribution is given by
<u>Percentile</u> is a value below which a percentage of the data falls.
For the waiting line in a Piggly Wiggly checkout, 80th percentile will be
h = 11.3
<u>The 80th percentile of waiting times is </u><u>11.3 minutes.</u>
Answer:
b) -2/3
Step-by-step explanation:
2X + 3Y = - 12
3Y = -2X - 12
Y = - 2/3X - 6
SLOPE = - 2/3
