Which is the equation of a line that has a slope ot 1/2 and passes through the point 2, -3​
mamaluj [8]

Answer:

y=1/2x-4

Step-by-step explanation:

You are given the slope, 1/2. So you can plug it into the equation (y=mx+b)

You also need to plug in the x and y coordinate your given so you'll have

-3=1/2(2)+b. Then you solve for b, which is -4. You now have your answer, y=1/2x-4.

How is 3 divided by 1.4 ...2.14? Working please!
musickatia [10]
Turn 1.4 into a whole number. Which makes 1.4 to 14. We know that 3 has a decimal point at the end. So move the decimal point of 3 to the right, making it 30. Now do 30/14. You will get...

30/14 = 2.14

Which of the following are solutions to the equation sinx cosx = 1/4? Check all that apply.
N76 [4]
The solution is <span>B. π/12+nπ

</span>proof 
sinx cosx = 1/4 is equivalent to  2 <span>sinx cosx = 1/2 or sin2x =1/2
so 2x = arcsin(1/2) = </span>π/6 + 2nπ,  so x = π/12+nπ

Below is the normal distribution curve for height (inches) of NBA basketball players.
VladimirAG [237]

Answer:  standard deviation = 8

This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".

Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.
