4 rational numbers between 3/8 and 2/5

Answers

Step-by-step explanation:

3/8 = 15/40= 75/200

2/5 = 16/40 = 80/200

-> 4 rational numbers between 75/200 and 80/200 are 76/200, 77/200, 78/200, 79/200

The scores of the top ten finishers in a recent golf tournament are listed below. find the median score. 67 67 68 71 72 72 72 72 73 76a. 72
b. 71
c. 73
d. 67

Answers

Answer:

(A) 72

Step-by-step explanation:

Find the middle(or middle two) values:

67 67 68 71 72 72 72 72 73 76

1 2 3 4 5 6 7 8 9 10

^ ^

Now find the mean of the two middle values: (72+72)/2 = 72.

Therefore, the median value is 72 or (A).

Final answer:

The median score of the top ten finishers in the golf tournament is 72.

Explanation:

To find the medianscore, we need to arrange the scores in ascending order. The scores are: 67, 67, 68, 71, 72, 72, 72, 72, 73, 76. The middle score is the median. Since there are 10 scores, the middle score is the 5th score in the ordered list, which is 72. Therefore, the median score is 72.

Simplify a - {5b - [a - (3b - 2c) + c - (a - 2b - c)]}.-a - 6b + 4c

a - 6b + 4c

a - 10b + 4c

-a + 10b + 4c

Answers

a - {5b - [a - (3b - 2c) + c - (a - 2b - c)]}
= a - 5b - a - 3b + 2c + c - a + 2b + c
= -a - 6b + 4c

answer is -a - 6b + 4c (first choice)

your answer should be -6b+4c

Using a tape measure Becky Jo found that the circumference of the great redwood was 900cm. She estimated that its diameter was 300cm. Was her estimate a little too large or a little too small? Why?

Answers

The length of the circle - the product of the diameter and the number Pi
l = dπ
l = 900cm
π ≈ 3,1415 przyjmiemy wartość 3
900cm = d* 3 [:3
d = 300cm
Becky rounded value of Pi , hence the difference in result

More accurate calculation

l = d*π
900cm = d*3,1415
d = 900cm : 3,1415 = 286,49cm

Becky overestimated the outcome

Find the equation of the circle whose center and radius are given.center ( 5, 6), radius = 3

Answers

Answer:

$(x-5)^2+(y-6)^2 =9$

Step-by-step explanation:

The equation of circle is given by:

$(x-h)^2+(y-k)^2 = r^2$

where,

(h, k) is the center

r is the radius of the circle.

As per the statement:

Given: center ( 5, 6), radius = 3 units

⇒(h, k) = (5, 6) and r = 3 units

Substitute these in [1] we have;

$(x-5)^2+(y-6)^2 = 3^2$

⇒ $(x-5)^2+(y-6)^2 =9$

Therefore, the equation of the circle is, $(x-5)^2+(y-6)^2 =9$

the general formula of the circle is (x-h)^2 + (y-k)^2 = r^2
where (h,k) the center of the circle and r is the radius
so , the equation is (x-5)^2 + (y-6)^2 = 9
