Answer:

Null hypothesis: There is no significant difference in aging time of old methods of culturing cheese and the new method of culturing cheese.

Or

H0:μ1=μ2.

Alternative hypothesis: The new method of culturing cheese reduces aging time as compared to old method of culturing cheese

Or

Ha:μ1>μ2.

Step-by-step explanation:

We are interesting in investigating that whether the the new method of culturing cheese significantly reduces aging time compared to old method of culturing cheese. Null hypothesis always contain equality so, in null hypothesis we make the statement of no difference among both methods of culturing cheese. So, null hypothesis can be written as

Null hypothesis: There is no significant difference in mean aging time of old methods of culturing cheese and the new method of culturing cheese.

Or symbolically it can be written as

H0:μ1=μ2

whereas μ1 represents mean aging time for old method and μ2 represents mean aging time for new method.

Alternative hypothesis includes difference in methods which in this case is the claim about new method of culturing cheese reduces aging time. So, it means that mean aging time of old method will be greater than mean aging time of new method. So, the alternative hypothesis can be written as

Alternative hypothesis: The new method of culturing cheese reduces mean aging time as compared to old method of culturing cheese

Or symbolically it can be written as

Ha:μ1>μ2

whereas μ1 represents mean aging time for old method and μ2 represents mean aging time for new method.

Answer:

The weighted average for the following score is   [tex]W = 85.72[/tex]

Step-by-step explanation:

From the question we are told that

  The worth of the lab score is  23% of  total grade  i.e 0.23

   The worth of each major test is 22.5% of the total grade  0.225

   The  worth of the final  exam is  32% of the total  grade 0.32

   The  score on lab is 85  

    The score on first major test is 95

    The score on the second major test is 91

     The score on the final exam is  76

Generally the weighted average is mathematically represented as

     [tex]W  =  [0.23 *  85 ]+ [0.225 * 95] +  [0.225 * 91 ]+ [0.32 *76  ][/tex]

=>  [tex]W = 85.72[/tex]

Answer:

1/2x+7

Step-by-step explanation:

seven more than half of a number is  (x/2) + 7.

The correct option is (C).

Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.

We have to find an algebraic expression which represents the phrase "seven more than half of a number".

Consider a number x,

half of x = (x/2)

seven more than half = (x/2) + 7

Hence, seven more than half of a number is  (x/2) + 7.

Answer:

5c+4p = 18.50

2c+4p = 11.20

Cost of cup = $2.4

cost of pretzels = $1.625

Step-by-step explanation:

Note:

2 cups of hot cocoa and 4 pretzels for $11.30

Computation:

5c+4p = 18.50........eq1

2c+4p = 11.30........eq2

Where c = cost of cup

p = cost of pretzels

From eq1 - eq2

3c = 7.20

c = 2.4

Cost of cup = $2.4

5c+4p = 18.50

5(2.4) + 4p = 18.50

p = 1.625

cost of pretzels = $1.625

The given histogram is uniform histogram.

Since we know that,

A histogram is a graphical depiction of data distribution in statistics. The histogram is represented by a series of neighboring rectangles, with each bar representing a different type of data.

Statistics is a branch of mathematics that is used in a variety of areas. When numbers are repeated in statistical data, this repetition is known as Frequency, and it may be put down in the form of a table, which is known as a frequency distribution.

A Frequency distribution may be represented graphically using several types of graphs, one of which is a Histogram.

Based on the frequency distribution of the data, the histogram may be categorised into distinct categories. Normal distribution, skewed distribution, bimodal distribution, multimodal distribution, comb distribution, edge peak distribution, dog food distribution, heart cut distribution, and so on are all examples of distributions. These many sorts of distributions can be represented by the histogram.

A histogram can be of several types:

Histogram that is uniform

Histogram with symmetry

Histogram with two modes

Probability distribution histogram

A uniform distribution demonstrates that the number of classes is too small, with the same amount of components in each class. It might involve a distribution with many peaks.

Since we can see in the given histogram,

The average frequency  is 5

And almost all the bars are ending at 5

Hence,

This histogram is uniform histogram.

Step-by-step explanation:

Answer:

3 miles

Step-by-step explanation

Distance = rate x time

d=rt

rate = 9

time= 20 minutes but we need this in terms of hours since the rate is 9 miles per hour

t = 20/60 = 1/3

so d = 9(1/3) = 3 miles

Step-by-step explanation:

the volume of a box is always

length × width × height

in our first case here :

11 × 6.4 × 3 = 211.2 cm³

the volume of the small boxes is

3 × 2 × 1 = 6 cm³

the volume of the large box is

15 × 12 × 10 = 1,800 cm³

so,

1800/6 = 300 small boxes will fit into the large box.

because the dimensions of the small boxes are factors of the dimensions of the large box (3 is a factor of 15, 2 is a factor of 12, 1 is a factor of 10), it will be a perfect fill without any unused leftover pockets of space.

so, truly 300 small boxes will fit into the large box.
