Service time for a customer coming through a checkout counter in a retail store is a random variable with the mean of minutes and standard deviation of minutes. Suppose that the distribution of service time is fairly close to a normal distribution. Suppose there are two counters in a store, customers in the first line and customers in the second line. Find the probability that the difference between the mean service time for the shorter line and the mean service time for the longer one is more than minutes. Assume that the service times for each customer can be regarded as independent random variables. Round your answer to two decimal places (e.g. 98.76).

Step-by-step explanation:
A mouse is moving through a maze and must make four turns where it can go either left or
right. The mouse will escape the maze if it makes three lefts and one right, in any order.
(a) To the right, draw a tree diagram
of all possible routes the mouse
could take.
(b) Using your tree diagram, create
an organized list of the routes. For
example, a route of right, left, left,
right could be listed as RLLR.
(C) What is the probability the mouse
escapes the maze if all turns are
randomly made?

Some researchers have conjectured that stem-pitting disease in peach-tree seedlings might be controlled with weed and soil treatment. An experiment is conducted to compare peach-tree seedling growth when the soil and weeds are treated with one of two herbicides. In a field containing 20 seedlings, 10 are randomly selected throughout the field and assigned to receive herbicide A. The remainder of the seedlings is assigned to receive herbicide B. Soil and weeds for each seedling are treated with the appropriate herbicide, and at the end of the study period, the height in centimeters is recorded for each seedling. The following results are obtained: Herbicide A = 94.5 cm s1 = 10 cm Herbicide B = 109.1 cm s2 = 9 cmWhat is a 90% confidence interval (use the conservative value for the degrees of freedom) for μ2 – μ1?
a. 14.6 ± 7.00
b. 14.6 ± 7.38
c. 14.6 ± 7.80
d. 14.6 ± 9.62
Answer:
A. 14.6 ± 7.00
Step-by-step explanation:
Formula for the confidence interval between the two mean is;
CI = (μ2 - μ1) ± z√[((s1)²/n1) + ((s2)²/n2)]
We are given;
μ1 = 94.5
μ2 = 109.1
s1 = 10
s2 = 9
n1 = 10
n2 = 10
The z-value at confidence interval of 90% is 1.645
Thus;
CI = (109.1 - 94.5) ± 1.645√[(10²/10) + (9²/10)]
CI = 14.6 ± 7.00
David can type a 50-page paper in 8 hours. Last month, David and Andy together typed a
50-page paper in 6 hours. How long would Andy take to type a 50-page paper by himself?
Answer:
12.5pages
Step-by-step explanation:
50pages ×6hours=300 and then we divide by 8 to get 37.5(the number of pages printed by david in 6 hours)
subtract 37.5 from 50 to find the number of pages printed by andy

5B. Using the balanced seesaw shown, find the ratio of lengths a/b in lowest terms.
Answer:
Lowest terms is 7:6
Step-by-step explanation:
A = 63
B = 54
Ratio is a:b = 63:54
63:54
Reduce 63 to lowest terms to get 7 by dividing 9.
63 ÷ 9 = 7
Reduce 54 to lowest terms to get 6 by dividing 9.
54 ÷ 9 = 6
So the reduced form 63:54 in ratio is 7:6.
7:6
I hope this helped!
Answer:
6:7
Step-by-step explanation:
weight * distance = weight * distance,
so 63 * d1 = 54 * d2
LCM(63,54) = 378
378÷63 = 6
378÷54 = 7
so the answer is 6:7

Solve the equation in two different ways. Choose one method of solving in detail 5x+7(x+1) = 5x - 21
Answer:
METHOD 1:
5x+7(x+1)=5x-21
5x+7x+7=5x-21
12x+7=5x-21
12x-5x=-21-7
7x=-28
x=28/7
x=4
METHOD 2:
5x+7(x+1)=5x-21
5x+7(x+1)=5x-21-5x
7(x+1)=-21
7x+7=-21
7x=-28
x=4
Step-by-step explanation:
METHOD 1:
5x+7(x+1)=5x-21
5x+7x+7=5x-21
12x+7=5x-21
12x-5x=-21-7
7x=-28
x=28/7
x=4
METHOD 2:
5x+7(x+1)=5x-21
5x+7(x+1)=5x-21-5x
7(x+1)=-21
7x+7=-21
7x=-28

Solve the equations
2^x – 5^y = 3 and 2^x-3 + 5 ^y-2 =21
You can substitute a = 2ˣ and b = 5ʸ to make both equations linear.
The first equation becomes
a - b = 3
In the second equation, first simplify the exponents:
2ˣ ⁻³ = 2ˣ × 2⁻³ = 1/8 × 2ˣ
5ʸ ⁻² = 5ʸ × 5⁻² = 1/25 × 5ʸ
so the second equation changes to
a/8 + b/25 = 21
Multiply both sides of this by 200 (the LCM of 8 and 25) to eliminate the fractions:
25a + 8b = 4200
Multiply both sides of the first equation by 8, then add the corresponding sides of both equations. This eliminates b and you can solve for a :
8 (a - b) + (25a + 8b) = 8 (3) + 4200
(8a - 8b) + (25a + 8b) = 24 + 4200
33a = 4224
a = 128
Plug this into the first equation to solve for b :
128 - b = 3
b = 125
Now solve for x and y. Notice that
128 = 2⁷
and
125 = 5³
so it follows that x = 7 and y = 3.
Alternatively, you can use logarithms. For example,
a = 2ˣ → log₂(a) = log₂(2ˣ ) → x = log₂(128) = 7
