F(-3) = 4(-3) - 3 = -12 - 3 = -15.
H(2) = -5(2) + 7 = -10 + 7 = -3.
F(-3) + H(2) = -15 + -3 = -18.
The solution is -18.
Answer:
The sample size is 4
Step-by-step explanation:
Null hypothesis: The mean is 2
Alternate hypothesis: The mean is less than 2
Mean = 3
sd = sqrt(variance) = sqrt(4) = 2
At 95% confidence level, t-value is 1.960
Assuming the lower bound of the mean is 1.04
Lower bound = mean - (t×sd/√n)
1.04 = 3 - (1.96×2/√n)
3.92/√n = 3 - 1.04
3.92/√n = 1.96
√n = 3.92/1.96
√n = 2
n = 2^2
n = 4
. The sum of angels in the triangle must be 180
Therefore
1) 180 - (40+85)= 55
2)180-(14+30)= 136
Answer:
See attached graph.
Step-by-step explanation:
To graph the equation, use its form y = mx+b to guide you.
Since y = 7x + 1 then m = 7 and b=1. Start on the y-axis at 1. Plot this points. From this point go up 7 units and over 1 units. Plot this point (1,8). Connect the points.
