Answer:
x = 12.77 cm
Step-by-step explanation:
In this problem, we will use trigonometry to find the missing value. I will use the 70 degree angle to find it.
12cm is the opposite value for 70, and x is the hypotenuse. We will use Sine to solve this problem.
Since we are missing the hypotenuse, we set up the equation like this -
x = 12/Sin(70)
This leads us to our answer, x=12.77 cm (rounded)
Algebraic Equation:
1/2p = 150
Solution:
150 ÷ 1/2 = 300
p = $300
The original price was $300
Answer: 25 computers will be selected
Step-by-step explanation:
Where: Z -value at 95% confidence = 1.96; SD = Standard deviation = 10 minutes; N = Sample size; Margin error = 4 minutesSubstituting;4 = 1.96*10/Sqrt (N)Sqrt (N) = (1.96*10)/4 = 4.9N = 4.9^2 = 24.01 ≈ 25
Answer:
i think the answer is -18x^(2)+9x+5
-18x^(2)+9x+5
Subtract 4x^2 from −14x^2
Answer:
1/22
Step-by-step explanation:
assuming that the marbles drawn are not replaced:
P(red) = 3/12 or 1/4
P(green) = 4/11
P(blue) = 5/10 or 1/2
multiply the probabilities together:
1/4 x 4/11 x 1/2 = 1/22
