Median is one of the measures of center of data points along with mean and mode. This refers to the number of value which appeared in the center when the values are arranged in increasing order. If there are even number of data points, this is the mean of the two centermost values. 
 
In this case, if we are to arrange the values, we have,
  
     89, 90, x, 95

x is the score in the final test. that is placed in between 90 and 95 considering that the median is between these two numbers.

       91.5 = (90 + x) / 2

The value of x from the equation is 93.

The score in the third test is therefore equal to 93.

diamong [38]

Answer:

5, 9, 13, 17, 21, .....

Step-by-step explanation:

To generate the sequence, substitute n = 1, 2, 3, 4, ..... into the rule

a₁ = 4(1) + 1 = 4 + 1 = 5

a₂ = 4(2) + 1 = 8 + 1 = 9

a₃ = 4(3) + 1 = 12 + 1 = 13

a₄ = 4(4) + 1 = 16 + 1 = 17

a₅ = 4(5) + 1 = 20 + 1 = 21

Chuy wants to buy a new television. The television costs $1,350. Chuy decides to save the same amount of money each week, for 27
mars1129 [50]

Answer: option C is the correct answer.

Step-by-step explanation:

The television costs $1,350. Chuy decides to save the same amount of money each week, for 27 weeks. After 8 weeks Chuy saved $440. This means that the amount that she saved per week is

440/8 = $55

If she saves $55 in 8 weeks, the number of weeks left is

27 - 8 = 19 week

Amount that she would save in 19 weeks is

19 × 55 = 1045

Total amount saved in 27 weeks is

1045 + 440 = $1485

Therefore, the conclusion that you can make about Chuy's plan is

C. Chuy will save more than he needs and will meet his goal in less than 27 weeks.

Answer:

The answer is 48.9 cm^2.

Step-by-step explanation:

Let's find the surface areas of the faces other than the base;

triangle area: b x h / 2

4 x 7 = 28, 28/2 = 14

in this case, there are three faces, so 14 x 3 = 42, and we add that with the base to get 48.9
