Answer:
2
Step-by-step explanation:
-3x ≤ -5
if we divide for a negative number we have to change the sign of the inequality
x ≥ 5/3
5/3 = 1,666
so the nearest integer number is 2
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
sinx-1 evaluates to s-1
<span>tanx+secx evaluates to t+sHere, you are trying to multiply two binomials together. To work this problem, we'll use the "F.O.I.L." method. First, we'll multiply the two First terms, the s and t together. Second, we'll multiply the two Outer terms, the s and s together. Third, we'll multiply the two Inner terms, the -1 and t together. Lastly, we'll multiply the two Last terms, the -1 and s together. The correct answer is st + s^2 - t - sThank you for posting your question. I hope that this answer helped you. Let me know if you need more help.

Answer:
The intial fee is $5
The equation to represent this is: y=12x+5
12 is the cost per hour x=hours y=total cost
Step-by-step explanation:
77-41=36
36/3=12
12*6=72
77-72=5
The answer is A. -4
It wouldn’t be the other answers bc:
square root of 4 is 2
0.4 is not equal to 4
1/4 is 0.25
