A 6 foot wide painting should be center on a 14 foot wide wall. how many feet X should be on each side of the painting
serious [3.7K]

Answer:

4 feet

Step-by-step explanation:

We start by subtracting the 6 from the 14, to get the leftover space on the wall, 8 feet. We then divide that by two, since if the painting is centered there will be two equally-sized spaces on either side of it. This means that X = 4 feet.

The line passes through the point -4, -8 and has a slope of 3/2 Rewrite an equation in a X plus BY equals C
amid [387]

Answer:

Step-by-step explanation:

(-4,-8)...x = -4 and y = -8

slope = 3/2

in y = mx + b form, the m is ur slope

now sub ur info into y = mx + b......we need to find b, the y intercept

y = mx + b

-8 = 3/2(-4) + b

-8 = -6 + b

-8 + 6 = b

-2 = b

so ur equation is : y = 3/2x - 2.....but u need it in another form

y = 3/2x - 2.....subtract 3/2x from both sides

-3/2x + y = -2 ....then u can multiply by -2 and get 3x - 2y = 4....just in case u dont want fractions

dezoksy [38]

Answer:

The probability that I mist sample 5 12-year-olds to find the first one who can pick out Colorado on a map is 1.  

Step-by-step explanation:

The research suggests that about 24% of 12-year-olds in the US can pick out the state of Colorado on a map. The probability always exceeds the probabilities of picking out 1 over 5 12-year-olds, which is 20%, in a sample is well-represented the 12-year-old population of the US. Hence, the answer is 1 (or 100%).
