Answer:
75% bigger
Step-by-step explanation:
Let the first number be x and the second be y.
So:
And:
-----30% less than x
Substitute in
Cross multiply
Collect like terms
Make x the subject
So, the average is:
Rewrite as:
Express as percentage
This means that the average is 75% bigger than the second number

Note: All triangles, by definition, have 3 (three) sides and 3 (three angles).
The triangle shown (in the "image attached") has three EQUAL side lengths. Therefore, the triangle shown is an "equilateral triangle" and has 3 (three) equal angles, as well.
All triangles by, definition, have 3 (three) angles that add up to "180° " .
Since each of the 3 (three) angles is equal; and the three angles are:
"∠A" , "∠B" , and "∠C" ;
We can find the measure of "∠A" ; denoted as: "m∠A" ; as follows:
______________________________________________________
m∠A = 180° ÷ 3 = 60° .

The answer is: " 60° " .
______________________________________________________
m∠A = " 60° " .

Answer:
0.11069
Step-by-step explanation:
We will assume that the trains pass by his house following a uniform distribution with values between 0 and 24. The probability of a train passing on a 9-hour time period is 9/24 = 3/8 = 0.375. Lets call Y the amount of trains passing by his house during that 9-hour period. Y follows a Binomail distribution with parameters 22 and 0.375.
P(Y ≤ 5) = P(Y = 0) + P(Y=1) + P(Y=2) + P(Y=3) + P(Y=4) + P(Y=5) =
I hope that works for you!
25% of 180 is 45.
You do the equation 25%*180 which equals to 45. The word of means multiply and the word is means equal
