One number is 23 more than another number. The sum of the two numbers is 83. Find the two numbers

X + (x+23) = 83

2x + 23 = 83

2x = 83 - 23 = 60

x = 60 / 2 = 30

30 +23 = 53

one is 53 another 30

2x + 23 = 83

2x = 83 - 23 = 60

x = 60 / 2 = 30

30 +23 = 53

one is 53 another 30

One number is 58, the other is 25.

Find the equation of the line that passes through the points (2,16) and (-1,7)

Use your slope formula (y2-y1)/(x2-x1) to get a slope of 3. Next you can use y=mx+b and fill in using one point and the slope and solve for b. 16=3(2)+b. b=10 y=3x+10

The correlation coefficient of the data on chick survival vs. Clutch size is –0.93. How would you interpret that correlation coefficient?

The correlation coefficient of the data on chick survival vs. Clutch size is –0.93. How would you interpret that correlation coefficient?

Answer: The correlation coefficient of the data on chick survival vs. Clutch size is –0.93. It means there is strong downhill (negative) linear relationship between chick survival and clutch size.

Correlation coefficient examines the strength and direction of the linear relationship between two continuous variables. The value of the correlation coefficient lies between -1 and 1.

Answer: There is strong negative correlation between chick survival and Clutch size.

Step-by-step explanation:

Given : The correlation coefficient of the data on chick survival vs. Clutch size is -0.93.

We know that when the correlation coefficient has value close to -1 or belongs to range -0.7 to -1, then we call it as strong correlation coefficient.

Since -0.93 is very close to -1, so it means that there is strong negative correlation between chick survival and Clutch size.

It means if chick survival increases then clutch size decreases or vica versa.
