The correct question is given below:
A health and fitness company is testing a newly designed exercise and weight loss program. It is suspected that the new program is more effective in assisting weight loss. A group of 220 volunteers is first separated into 6 groups, labeled A to F, based upon age and weight such that these qualities are similar within each group. The age and weight of the volunteer is initially measured. Within each group, participants are randomly assigned to either undergo the new exercise program or undergo a conventional exercise program. In addition, the daily calorie intake is set to a particular amount, either low, moderate or high, and maintained at that level for the duration of the program. At the end of six months, the percentage of weight lost is measured for each unit and the results are collected and compared.

Al must score 96 in his final test to get an average of 81.

An average or mean is one number chosen to represent a group of numbers; it is often the sum of the numbers divided by the number of numbers in the group.

If every number in a list is the same number, then the average of the numbers in the list is also this number. Every one of the diverse varieties of average shares this characteristic.

The sum of the  of the numbers 2, 3, 4, 7, and 9 is 25, the average of the numbers is equal to 25 divided by 5=5.

Let Al scores x on final test.

Average score on first 3 tests=76

Total score on first 3 tests=76×3=228

Total score in 4 tests=228+x

Average score of 4 tests=(228+x)÷4

Average to be obtained in 4 tests=81

therefore we can equate the two expressions to calculate x.

(228+x)÷4=81

or, 228+x=324

or,x=324-228

or, x=96

Hence Al needs to get 96 on his final test so that his average is 81.

Answer:

[tex]y = 120x [/tex]

Step-by-step explanation:

Equation of a straight line is

[tex]y = mx + b[/tex]

m= slope of line = rise/run which can be computed by taking two points on the line, finding the difference I the y coordinate values and dividing by the correspoding difference in their x coordinate values

b is the y-intercept where the line crosses the y-sxis

Looking at the graph we can see that the line crosses the y-sxis at the origin (0, 0) so the y-intercept is at y=0

The slope is determined by examining the two highlighted points (3, 360) and (2, 240)

Slope =

[tex] \frac{360 - 240}{3 - 2} = \frac{120 }{1} = 120[/tex]

So equation of line is

[tex]y = 120x + 0[/tex]

or

[tex]y = 120x[/tex]

The cliff is 98.89 feet tall.

In the attached diagram, we can there are two triangles forming. Small triangle involves Juan and tent and larger triangle involves Juan and cliff. As per the known fact, tan theta = perpendicular ÷ base. So, tan theta will be common for both the triangles. Hence, relating the components of tan theta, of both the triangles.

Smaller triangle :

tan theta = 10/45

Larger triangle :

tan theta = h/(400 + 45)

tan theta = h/445

Relating both the triangles as follows -

10/45 = h/445

Performing cross multiplication

10×445 = h×45

h = 4450÷45

h = 98.89 feet

Hence, the cliff is 98.89 feet tall.

The complete arithmetic sequence is 1, .25, -0.5, -1.25, -2

The arithmetic sequence is given as:

1, .25, blank, -1.25, blank

Replace the blanks in the arithmetic sequence with x and y

So, we have:

1, .25, x, -1.25, y

An arithmetic sequence has a common difference (d)

The common difference is calculated using

d = T2 - T1

So, we have

d = 0.25 - 1

d = x - 0.25

d = y + 1.25

Substitute d = x - 0.25 in d = 0.25 - 1

x - 0.25 = 0.25 - 1

This gives

x = 0.25 + 0.25 - 1

Evaluate the sum

x = -0.5

Substitute d = 0.25 - 1 in d = y + 1.25

0.25 - 1  = y + 1.25

This gives

y = 0.25 - 1 - 1.25

Evaluate

y = -2

Answer:

my result is 0 = -7 It has no solutions though since it is a contradiction

Using the percentage concept, it is found that:

a) Her tolerance is of (60 ±  6 minutes).

b) As a percentage, her tolerance times are of 60 minutes (± 10%).

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

[tex]P = \frac{a}{b} \times 100\%[/tex]

For this problem, the interval is between 54 and 66 minutes, that are both within 6 minutes of the mean of 60 minutes, thus:

a) Her tolerance is of (60 ±  6 minutes).

For item b, we want to find the tolerance as a percentage, that is, the percentage that the tolerance of 6 minutes is from the time of 60 minutes, hence:

P = 6/60 x 100% = 0.1 x 100% = 100%.
