Answer:
2x-17
Step-by-step explanation:
-3(x + 5) + 5(x – 2) + 8
Lets begin:
What is -3(x+5)? I do -3×x+(-3)×5=-3x-15.
So 5(x-2) is 5×x+5×(-2)=5x-10.
Now lets sum it:
-3x-15+5x-10=2x-25
And we have 8:
2x-25+8=2x-17
Answer:
Step-by-step explanation:
For the null hypothesis,
H0 : p = 0.63
For the alternative hypothesis,
Ha : p < 0.63
This is a left tailed test
Considering the population proportion, probability of success, p = 0.63
q = probability of failure = 1 - p
q = 1 - 0.63 = 0.37
Considering the sample,
Sample proportion, P = x/n
Where
x = number of success = 478
n = number of samples = 800
P = 478/800 = 0.6
We would determine the test statistic which is the z score
z = (P - p)/√pq/n
z = (0.6 - 0.63)/√(0.63 × 0.37)/800 = - 1.76
From the normal distribution table, the area below the test z score in the left tail 0.039
Thus
p = 0.039
Answer:
Step-by-step explanation:
Note that the expression is the difference of squares.
36 - 9m² = 6² - (3m)²
6² - (3m)² = (6 + 3m) (6 - 3m)
Your answer would be y = 4x + 3.
Since we are already given the slope, we just need to find the y-intercept. We can do this by writing the equation as y = 4x + b, and then substituting in the coordinates that we are given. This gives us:
-5 = (4 × -2) + b
-5 = -8 + b
b = 3
So now we can write the whole equation as y = 4x + 3.
I hope this helps!
