simplify the equation to solve it, remove unnessecary parentheses and spaces.
Answer:
62%
Step-by-step explanation:
8/ 13=61.54 round to 62%
Answer:
68 is what I'm getting for x
70 is the correct length of DH
Step-by-step explanation:
You can set up the proportion for this question.
99.2 / 62 = 112/(x + 2) Cross multiply
99.2 ( x + 2) = 62 * 112 Combine the right side
99.2(x + 2) = 6944 Use the distributive principle to remove the brackets.
99.2*x + 2*99.2 = 6944 Combine the factors on the left
99.2x + 198.4 = 6944 Subtract 198.4 from both sides
99.2x = 6944 - 198.4 Combine the terms on the right
99.2x = 6745.6 Divide both sides by 99.2
x = 6745.6/99.2
x = 68
DH = 70
Answer:
3
Step-by-step explanation:
Volume of sphere:
4/3 * pi * r^3
Surface Area of Sphere:
4 * pi * r^2
So if V = SA
4/3 * pi * r^3 = 4 * pi * r^2
<u>4</u>/3 * <u>pi</u> * r^3 = <u>4</u> * <u>pi</u> * r^2
1/3 * r^3 = r^2
1/3 * r = 1
r = 3
Answer:
0.035547
Step-by-step explanation:
We would be using z score formula to solve for this question
The formula for calculating a z-score is is
z = (x-μ)/σ
where x is the raw score = 18 in
μ is the population mean = 10.6 in
σ is the population standard deviation = 4.1 in
z score = 18 - 10.6/ 4.1
z score = 7.4 /4.1
z score = 1.80488
Using the normal distribution table to find the probability for the z score of 1.80488
Probability value from Z-Table:
P(z = 1.80488) = 0.96445
The probability that a fish caught there will be longer than 18 in is calculated as:
P(x>18) = 1 - P(z = 1.80488)
= 1 - 0.96445
= 0.035547
