Answer: y = 17x
Step-by-step explanation:
Note that the equation that will be used is: y = mx + b,in which m = slope and b = y-intercept.
Solve for b:
0 = 17(0) + b
Simplify:
0 = 0 + b
b = 0
Equation: y = 17(x)

The Isosceles triangle has two equal side
So 35 + 35 + the another angle = 180
The another angle = 110
The straight angle = 180 - 110 = 70
The Isosceles triangle = 70 + 70 + x = 180
So x = 40

2,-2 because it goes by the coordinate x,y.
Answer:
C
Step-by-step explanation:
Firstly, we set up the null and alternative hypothesis as follows;
The null hypothesis is;
H0: μ ≥ 12
The alternative hypothesis is;
Ha : μ < 12
Next step is to calculate the test statistic z
Mathematically;
z = (x - μ )/ σ /√n
= (11.58 - 12) /1.93/√(80
Test statistic z = -1.92
Now we proceed to find the probability value that is equal to the value of the test statistic. We can find this by using the standard normal table or NORMSTD function on excel
P(z < -1.92) = 0.0274
P-value = 0.0274
alpha = 0.05
From the above, we can see that
P-value < alpha
And because of this, we are going to reject the null hypothesis and therefore accept the alternative.
We then conclude that there is sufficient evidence to conclude that "The average battery life (between charges) of this model of tablet is at least 12 hours."
