Answer:

b = 1

Step-by-step explanation:

Given

8 = b - 1 + 8b, that is

8 = 9b - 1 ( add 1 to both sides )

9 = 9b ( divide both sides by 9 )

1 = b

Answer:

b = 1

Step-by-step explanation:

8 = b - 1 + 8b

<em>combine like terms</em>

8 = 9b - 1

<em>add 1 to both sides of the equation</em>

<em>8 + 1 = 9b - 1 + 1</em>

<em>8 + 1 = 9b</em>

9 = 9b

<em>divide both sides of the equation by 9</em>

9/9 = 9b/9

1 = b

Ground beef is packaged in small trays, intended to hold 1 pound of meat. A random sample of 45 packages in the small tray produ
user100 [1]

Answer:

There is sufficient statistical evidence to suggest that the average weight of the ground beef packaged in small trays is 1 pound

Step-by-step explanation:

Here we have to perform a t-test

Mean = Sample mean = 1.04 lb

μ = Population mean = 1 lb

s = Standard deviation of 0.19

n = Sample size = 45

Null hypothesis H₀ = 1

Alternative hypothesis Hₐ > 1

Therefore from

t=\frac{\bar{x}-\mu }{\frac{\sigma }{\sqrt{n}}} we have

t = 1.412

Critical t at 5% confidence level  = 1.68

at 5 % confidence level we obtain the probability P is;

P = 0.0825 > 0.05 Therefore we accept our null hypothesis that the average weight of ground beef per pack is 1 pound.

m_a_m_a [10]
In the given question, there are several information's of immense importance. using these given information's the required answer can be easily deduced. It has already been given that Tom has a total amount of $240. He bought 22 boxes of drinks at $4 per box. rest he spent on buying the 8 boxes of sandwiches.
A. The amount of money the drinks cost in total = (22 * 4) dollars
                                                                             = 88 dollars
So Tom spent $88 on the drinks
B. Now we have to first find the amount spent by Tom on the box of sandwiches.
Total amount spent by Tom on sandwiches = (240 - 88) dollars
                                                                     = 152 dollars
Then the amount of money spent by Tom for buying 1 box of sandwich = (152/8) dollars
                                                                                                                   = 19 dollars
So Tom had to pay $19 for buying a single box of sandwich.
