Answer:
-2
Step-by-step explanation:
6i-5=-17
6i=-17+5
6i=-12
i=-12/6
i=-2
Y = 1/4 x - 2
=> a linear function => a straigh line
=> slope = the coefficient of x => slope = 1/4
=> x = 0 => the y-intercept = -2
=> y = 0 => 0 = 1/4 x - 2 =>x = 8 => point (8,0)
With all that information you can identify the graph because it is a straight line that passes through (0,-2) and (8,0), its inclination (slope) is 1/4, and the graph goes through the quadrants I, III and IV (there are no points in the quadrant II)..
Answer:
84.42
Step-by-step explanation:
Put the given value where X is, and do the arithmetic.
Y = 31.72 + 0.62(85) = 31.72 +52.7 = 84.42
The predicted course grade is 84.42.
Answer:
52.5
Step-by-step explanation:
Find inner square (7 * 7 = 49), then find outer triangles (.5*7=3.5 for both) then u get 52.5 plz mark 5 str, helpfull, and brainliest!
In order for the sum to be greater than 7, there are a few possible combinations which are shown below:
The probability for each individual dice to roll a certain number is:
If we want both to roll an exact number we have:
Any of the four probabilities can happen for our requirements to be met, therefore the total probability of at least one of them happening is the sum of all the probabilities:
For the sum of the dices to be not be divisible by 2, the result must be an odd number. The combinatios that could result in that are:
Which gives us a total of 18 possibilities. Since the probability of each of this happening is equal to 1/36, then the total probability is given by 18 times that, which results in the below:
