Answer:
184
Step-by-step explanation:
SA = 2LW + 2LH + 2WH
SA = 2(5 × 4) + 2(5 × 8) + 2(4 × 8)
SA = 2(20) + 2(40) + 2(32)
SA = 40 + 80 + 64
SA = 184

The Jefferson Valley Bank once had a separate customer waiting line at each teller window, but it now has a single waiting line that feeds the teller windows as vacancies occur. The standard deviation of customer waiting times with the old multiple-line configuration was 1.8 min. Listed below is a simple random sample of waiting times (minutes) with the single waiting line. Use a 0.05 significance level to test the claim that with a single waiting line, the waiting times have a standard deviation less than 1.8 min. What improvement occurred when banks changed from multiple waiting lines to a single waiting line?
Answer:
There will be sufficient evidence to conclude. A further explanation is provided below.
Step-by-step explanation:
The given values are:
[tex]\sigma=1.8[/tex]
[tex]\alpha=0.05[/tex]
[tex]n=10[/tex]
As we know,
[tex]\bar{x}=\frac{\Sigma x_i}{n}[/tex]
[tex]=\frac{71.5}{10}[/tex]
[tex]=7.15[/tex]
The standard deviation will be:
⇒ [tex]s=\sqrt{\frac{1}{n-1} \Sigma(x_i- \bar{x})^2 }[/tex]
On substituting the values, we get
⇒ [tex]=\sqrt{\frac{1}{10-1} [(6.5-7.15)^2+...(7.7-7.15)^2]}[/tex]
⇒ [tex]=\sqrt{\frac{1}{9} [(6.5-7.15)^2+...(7.7-7.15)^2]}[/tex]
⇒ [tex]=0.477[/tex]
According to the question,
Hypotheses:
[tex]H_o: \sigma=1.8[/tex]
[tex]H_a: \sigma<1.8[/tex]
The test statistic will be:
⇒ [tex]X^2=\frac{(n-1)s^2}{\sigma^2}[/tex]
⇒ [tex]=\frac{(10-1)\times 0.477^2}{1.8^2}[/tex]
⇒ [tex]=\frac{2.0477}{3.24}[/tex]
⇒ [tex]=0.632[/tex]
Thus the above is the correct response.
Mary bought 2 large popcorn buckets and 4 small drinks for $20. Linda bought 2 large popcorn buckets and 2 small drinks for $14. What was the cost for the large popcorn and the small drink?
Answer:
the cost for the large popcorn and the small drink is $4 and $3 respectively
Step-by-step explanation:
The computation of the cost for the large popcorn and the small drink is shown below:
Let us assume the cost of the large popcorn be x
ANd, the small drink cost be y
Now as per the question
2x + 4y = $20
2x + 2y = $14
Now subtract equation 2 from equation 1
2y = $6
y = $3
Now for x it is
2x + 12 = $20
2x = $8
x = $4
Hence, the cost for the large popcorn and the small drink is $4 and $3 respectively
4x + 8 - 9x = -17 what is x\
and the x has to be the same for each
Answer:
x = 5
Step-by-step explanation:
4x + 8 - 9x = -17
combine like terms:
-5x = -25
divide both sides of the equation by -5:
x = 5
Answer:
x=5
Step-by-step explanation:
4x-9x+8=-17
-5x+8=-17
subtract 8 from both sides and you get:
-5x=25
divide 5 from both sides, and you get x=5! :)

The weight of a bucket of fish was more than 23 pounds. Doria wants to write an inequality for the weight of the bucket of fish. She uses the variable w to represent the weight. Which inequality should Doria write? w greater-than negative 23 w greater-than 23 w less-than 23 w less-than negative 23
Answer:w is greater than 23
Step-by-step explanation:
Given
The weight of the bucket was more than 23 pounds i.e.

Step-by-step explanation:
200.00 / 25.50 = 7 games
how do you multiply add and divide fractions?
Answer:
If the denominators are not the same: First, make them the same. Then add or subtract like fractions with the same denominators.
Step-by-step explanation:
the first step when multiplying fractions is to multiply the two numerators. the second step is to multiply the two denominators. simplify the new fractions. the fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator.
to add or subtract fractions they must have the same denominator. if the denominators are already the same then it is just a matter of either adding or subtracting the numerators if the denominators are difrent then a common denominator needs to be found.

What is the distance from -7 to 5 on a number line?
2
4
-12
12
Answer:
12 units
Step-by-step explanation:
Find the absolute value of the difference , that is
d = | - 7 - 5 | = | - 12 | = 12 or
d = | 5 - (- 7) | = | 5 + 7 | = | 12 | = 12
The distance from -7 to 5 on a number line is 12 units. This distance between two integers is calculated by using a number line and the absolute value of the difference between those two integers.
What is a Number line?A number line is a graph for the real numbers.It is used to represent the integers on it at a regular interval. It is also used for finding arithmetic operations like the addition and subtraction of integers.The positive integers lie on the right side of the number line and the negative integers lie on the left side of the line The zero lies at the center of the line which separates the positive and negative integers.How to calculate the distance between two integers on a number line?For calculating the distance between two integers, count every integer in between themA faster way of finding the distance between the two integers is by taking the absolute value of their differenceIf A and B are two integers, then the distance between them is given by |B - A|Calculating the distance from -7 to 5 on the number line:
⇒ | 5 - (-7) |
⇒ | 12 |
= 12 units
Therefore, there are 12 units in between the given two integers -7 and 5 on a number line which is shown below

Answer:

Step-by-step explanation:
In this diagram we are given the hypotenuse (39) and the side adjacent to the angle x. The cosine function relates the hypotenuse and adjacent side as follows:
cos x = 28/39
Using the inverse cosine function on a calculator, we get x = 0.7699 radian, which converts to degrees if we multiply this result by 180/π:
Angle x, in degrees, is 44.1 degrees, which is to the nearest tenth.

Answer:
(a) She is 280m from her starting position
(b) 200m west then 80m south
Step-by-step explanation:
(a) 80m + 200m
= 280m
(b) First she walked 80m north n 200 east
If she want to get back to her starting position she will have to travel the same distance in the opposite direction
Opposite of East is West n opposite north is south
so she will have to go 200m west n then 80m south
