D) moderate negative association

Answers

Answer 1

Answer:

Answer:

C) weak negative association

Step-by-step explanation:

As X increases, Y generally decreases. So this is a negative association. Because the points are widely scattered, it is also a weak association. So the answer is C.

Answer 2

Answer:

the answer is c because the graph is going down

470 + how many tens = 1000? Tick the correct option A) 530 B) 430 C) 53

Answers

Answer: A) 530

Step-by-step explanation:

1000-470=530

Final answer:

To find out how many tens are needed to add to 470 to equal 1000, subtract 470 from 1000 and divide the difference by 10.

Explanation:

To find out how many tens are needed to add to 470 in order to equal 1000, we need to subtract 470 from 1000. This will give us the difference, which is 530. Since each ten is worth 10, we divide the difference by 10 to find out how many tens are needed. So, 530 divided by 10 equals 53. Therefore, the correct option is C) 53.

Write the statement for the problem in mathematical language. Use x for the tens digit and y for the unit digits in the two digit numbers. Find the two-digit number which is 2 times the sum of its digits

Answers

Answer:

Step-by-step explanation:

A two-digit number (xy) will have the value 10x+y. The sum of its digits is x+y.

You want ...

10x +y = 2(x +y)

1 ≤ x ≤ 9

0 ≤ y ≤ 9

The equation can be simplified to ...

8x = y

The only single-digit values for x and y that satisfy the requirements are ...

x = 1, y = 8

The two-digit number of interest is 18.

_____

Check

Its sum of digits is 1+8 = 9. 2×9 = 18.

_____

Comment on the relationship in the problem

What is the simplified expression for 2(x - 5)?

Answers

If you would like to know the simplified expression for 2 * (x - 5), you can find this using the following steps:

2 * (x - 5) = 2 * x - 2 * 5 = 2 * x - 10

The correct result would be 2 * x - 10.

The answer would be 2x-10

Urgentthe area of a square field is 60025m square.a man cycles along its boundary at 18 km per hour
in how much time will he return at starting point

Answers

Area of square field = 60025 m

Thus, side = √60025 = 245 m.

Perimeter = 245 * 4 = 980 meters

Speed = 18 kmph = 5m/s

Time = Distance / speed

= 980 / 5

= 196.

Thus, it will take 196 seconds for the man to return at the starting point.

$Area=60025\ m^2\ \ \ and\ \ \ Area=a^2\n\n\ \ \ \Rightarrow\ \ \ a^2=60025\ m^2 \ \ \Rightarrow\ \ \ a=245\ m\n\n\ \Rightarrow\ \ \ the\ perimeter\ of\ a\ square:\n\n.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ P=4a=4\cdot245\ m=980\ m=0.98\ km\n\n Speed=18 (km)/(h) \ \ \ and\ \ \ Speed= \frac{\big{P}}{\big{time}} \n\n18= \frac{\big{0.98}}{\big{time}}\n\n\ \ \ \Rightarrow \ \ \ time= \frac{\big{0.98}}{\big{18}}\ hr=\frac{\big{0.98}}{\big{18}}\ \cdot3660\ s=196\ s=3\ min\ 16\ s\n$
