Answer:

352 students

Step-by-step explanation:

Given

See attachment for table

n = 400

Required

Attendance of students in this year's show

First, we calculate the mean of the table

Mean= \frac{\sum x}{n}

So, we have:

Mean= \frac{85\% + 91\% + 92\% + 87\% +84\% + 89\%}{6}

Mean= \frac{528\%}{6}

Mean= 88\%}

Multiply the mean by the total students

Expected = Mean * n

Expected = 88\% * 400

Expected = 352

The basal energy rate is the daily amount of energy (measured in calories) needed by the body at rest to maintain body temperatu
katovenus [111]
Given :
A = <span>70 years old
H = 172 cm
W = 55 kg

so calculate the the basal energy rate B
B = </span><span>655.096 + 9.563W +1.85H - 4.676A
</span><span>where B is the basal energy rate (in calories), W is the weight (in kilograms), H is the height (in centimeters), and A is the age (in years)
substitute the given
B = </span>655.096 + 9.563(55) +1.85(172) - 4.676(70)
B = 1171.941 cal is the basal energy rate, since he is prescribed for 1000 cal per day is not enough because basal energy is the calorie needed at rest only how about the calorie needed for the daily acivities.

What are the solutions to the system of equations?
svet-max [94.6K]

Answer:the third option is correct

Step-by-step explanation:

The system of equations are

y = 2x^2 - 5x - 7 - - - - - - - - - - -1

y = 2x + 2 - - - - - - - - - - - - - 2

We would equate equation 1 and equation 2. It becomes

2x^2 - 5x - 7 = 2x + 2

2x^2 - 5x - 2x - 7 - 2 = 0

2x^2 - 7x - 9 = 0

We would find two numbers such that their sum or difference is -7x and their product is - 18x^2. The two numbers are 2x and - 9x. Therefore

2x^2 + 2x - 9x - 9 = 0

2x(x + 1) - 9(x + 1) = 0

2x - 9 = 0 or x + 1 = 0

2x = 9 or x = - 1

x = 9/2 = 4.5

Substituting x = 4.5 or x = -1 into equation 2, it becomes

y = 2 × 4.5 + 2 or y = 2 × - 1 + 2

y = 11 or y = 0

Therefore, the solutions are

(4.5, 11) (- 1, 0)
