Answer:
22
Step-by-step explanation:
3x = x+44(base angle of isosceles triangle are equal)
2x = 44
x = 22
Answer:
6.68% or 0.0668
Step-by-step explanation:
Mean sheet length (μ) = 30.05 inches
Standard deviation (σ) = 0.2 inches
In a normal distribution, for any length X, the z-score is determined by the following expression:
For X = 29.75, the z-score is:
A z-score of -1.5 corresponds to the 6.68th percentile of a normal distribution.
Therefore, the probability that a sheet selected at random will be less than 29.75 inches long is 6.68%.
Answer:
im not sure but just multiply the length times width and height
Step-by-step explanation:
Trini took 74 photos
<em><u>Solution:</u></em>
Given that Trini took some photos
The number of photos she took is a two-digit number
Let the number in unit place be x and the number in tens place be y
Then the two digit number is yx
Given that sum of digits is 11
Therefore,
x + y = 11 ---- eqn 1
The tens digit is 3 more than the ones digit
Therefore, we frame a equation as,
y = 3 + x ---- eqn 2
<em><u>Solve eqn 1 and eqn 2 to get value of "x" and "y"</u></em>
Substitute eqn 2 in eqn 1
x + 3 + x = 11
2x + 3 = 11
2x = 11 - 3
2x = 8
x = 4
Substitute x = 4 in eqn 2
y = 3 + 4 = 7
Thus the two digit number is 74. Thus he took 74 photos
