The answer is A. The only calculations were doing here are addition and subtraction and it doesn’t matter what order u do them in. If there was any multiplying or division here it would be different. The answer is A. Also can I get brainliest please?

Step-by-step explanation:

Right now, we would solve everything within the parenthesis first.

(8 - 16) + (8 + 6)

(-8) + (14)

14 - 8

6

But if we remove the parenthesis, it doesn't matter what order we do things in.

8 - 16 + 8 + 6

8 + 8 - 16 + 6

16 - 16 + 6

6

The reason why both of these are the same, is because the only calculations we're doing are addition and subtraction, which don't care about parenthesis.

Answer:

A

Find the probability of having 2,3 or 4 successes in five trials of a binomial experiment in which the probability of success is
dexar [7]

Answer:

65.3%.

Step-by-step explanation:

The general formula is:

nCr p^r (1 - p)^(n-r)    where n = number of trials, p =probability of success on one trial , r = the given number of successes

So for 2, 3 or 4 success ;

probability = 5C2 (0.4)^2 (0.60)^(5-2) + 5C3 (0.4)^3 (0.60)^(5-3)

                      +  5C4 (0.4)^4 (0.60)^(5-4)

= 0.3456 + 0.2304 + 0.0768

= 0.6528.

A shock bolt follows a poison curve with an ability to perform 7 shocks every 10 min what are the odds of a random shock bolt be
Serhud [2]
0% chance because there can only be 7 shocks per 10 minutes. Or 7*3 shocks per 10*3 minutes (21 per 30), so it is impossible.

Y=3x+2 is the equation of a straight line graph. Where does it cross the y-axis?
tamaranim1 [39]
The line crosses the y-axis at point (0,2). You know this because the slope intercept form is y=mx+b. y is any point on the y-axis. m is the slope of the line. x is and point on the x-axis. Finally, b is the y-intercept or where the line crosses the y-axis. As a result, your equation has a 2 for b. So, your answer would be: the line crosses the y-axis at point (0,2). 2 being where the line crosses the y-axis.

(0,1),(2,5),(3,7) in an equation
12345 [234]

The equation that gives the coordinates (0,1), (2,5), (3,7) is y =2x + 1.

Step-by-step explanation:

Step 1; We need to determine the equation relating the x to the f(x) values from the given coordinates. y is the dependent value whereas x is the independent value i.e. y's value depends on x's value.

Step 2; If we multiply the x value with 2 and add the resulting answer with 1 we get the y value.

y = 2x + 1 is the equation that relates the values in the table.

Step 3; Now we substitute the values in the equation to see if it's correct.

For x = 0, y = 2(0) + 1 = 0 + 1 = 1,

For x = 2, y = 2(2) + 1 = 4 + 1 = 5,

For x = 3, y = 2(3) + 1 = 6 + 1 = 7.

So the equation that gives the coordinates (0,1), (2,5), (3,7) is y =2x + 1.
