Let x represent the dollar amount spent on supermarket impulse buying in a 10-minute (unplanned) shopping interval. Based on a newspaper article, the mean of the x distribution is about $34 and the estimated standard deviation is about $7. A button hyperlink to the SALT program that reads: Use SALT. (a) Consider a random sample of n = 80 customers, each of whom has 10 minutes of unplanned shopping time in a supermarket. From the central limit theorem, what can you say about the probability distribution of x, the average amount spent by these customers due to impulse buying
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Population mean (Mp) = 34
Population standard deviation (sd) = $7
Number of customers (n) = 80 customers
According to the central limit theorem:
If the number of samples is large (usually ≥ 30), then the distribution will be normal and mean of sample will be the same as the mean of population.
Population mean(Mp) = sample mean(Ms)
Mp= Ms
$34 = $34
Sample standard deviation = standard error
Standard Error(SE) = (population standard deviation / √n)
SE = 7 / √80
SE = 7 / 8.9442719
SE = 0.7826237 = $0.78
Hence, sample distribution is Normally distributed with a mean of $34 and standard deviation of $0.78

Calculate the density of a rock that has a mass of 454 g and a volume of 100.0 cm3.
Answer:
4.54 g/cm^3
Step-by-step explanation:
d = m/v
d = 454 g ÷ 100.0 cm^3
d = 4.54 g/cm^3

Mia is mixing nuts and cereal squares to make 12 pounds of trail mix. Nuts cost $8 a pound, and cereal squares cost $3 a pound. If Mia wants her cost for the trail mix to be $5.50 a pound, how many pounds of nuts and how many pounds of cereal squares should she use?
Step-by-step explanation:
If n is pounds of nuts, and c is pounds of cereal squares, then:
n + c = 12
8n + 3c = 5.5(12)
Solve with substitution:
8n + 3(12 − n) = 5.5(12)
8n + 36 − 3n = 66
5n = 30
n = 6
c = 12 − n
c = 6
So Mia should use 6 pounds of nuts and 6 pounds of cereal squares.

Answer: C) f(-4) = 54
GIVE ME A THANKS
Step-by-step explanation:
f(x) = 7 ( 3 - x ) + 5
f(-4) = 7 ( 3 - (-4)) +5
f(-4) = 7 ( 7 ) + 5
f (-4) = 49 + 5
f (-4) = 54

Find the y-intercept of a line that passes trough (-7,9) and has a slope of 3
Answer:
(0,30)
Step-by-step explanation:
y=mx+b
9=3(-7)+b
9=-21+b
30=b
y-intercept (0,30)
Answer:
y = 3x + 30
Step-by-step explanation:
Slope intercept form [ y = mx + b ] where m = slope and b = y-intercept.
Solve for the y-intercept with the gaven variables.
y = 3x + b
9 = 3(-7) + b
9 = -21 + b
30 = b
y = 3x + 30

The midpoint of a segment has coordinates (–7, 4). If one endpoint of the segment has coordinates (6, –2), what are the coordinates of the other endpoint? Write the ordered pair in the blanks below.
Answer:
(-20, 10)
Step-by-step explanation:
(6, -2) -> (-7, 4)
left 13 and up 6
-7 left 13 is -20
4 up 6 is 10
(-20, 10)
If one endpoint of the segment has coordinates (6, –2),
the coordinates of the other endpoint is (-20,10)
Explanation :
The midpoint of a segment has coordinates (–7, 4). If one endpoint of the segment has coordinates (6, –2)
Let (x2,y2) be the other end point
First end point (x1,y1) is (6,-2)
Lets apply midpoint formula to find other endpoint
[tex](\frac{x_1+x_2}{2} ,\frac{y_2+y_2}{2} )[/tex]
Plug in the values inside the formula and make it equal to (-7,4)
[tex](\frac{x_1+x_2}{2} ,\frac{y_2+y_2}{2} )\\(\frac{6+x_2}{2} ,\frac{-2+y_2}{2} )=(-7,4)\\\frac{6+x_2}{2} =-7\\6+x_2=-14\\x_2=-14-6\\x_2=-20\\\\\\\\\frac{-2+y_2}{2}=4\\-2+y_2=8\\y_2=8+2\\y_2=10[/tex]
Other endpoint is (-20,10)
