I’ll be happy to help!
Since a right angle is equal to 90 degrees, we can add the 67+90 which equals 157, so since a triangle is equal to 180, we can subtract 180-157.
180-157= 23
The answer for x is 23!
Answer:
0.651%
Step-by-step explanation:
using Binomial expansion: nCr*p^n*(1-p)^(n-r)
probability he will get at least 5 hits in the game = probability he will get 5 hits in the game + probability he will get 6 hits in the game + probability he will get 7 hits in the game = 7C5*0.215^5*(1-0.215)^2 + 7C6*0.215^6*(1-0.215)^1 +7C7*0.215^7*(1-0.215)^0 = 21* 0.0004594*0.616225 + 7*0.00009877*0.785 + 1*0.000021235 = 0.00651 = 0.651%
Answer:
32
Step-by-step explanation:
To compare how much more Lola hiked we need the miles that each one hiked.
Elton hiked 16 miles each day for 12 days, the total amount of miles he hiked we can found by multiplying 16 by 12:
16miles(12) = 192 miles
Lola hiked 14 miles each day but for 16 days, so the total amount of miles she hiked can be found by multiplying 14 by 16:
14miles(16days) = 224
The difference of miles we found by subtracting 192 (elton's miles) from 224 (lola's miles)
224 - 192 = 32
Answer: Yes, it will be enough.

I will answer this in English:
We have 27 students and 81 units, we want to give 3 units to each student.
This is only possible if the quotient betwen 81 and 3 must be bigger than 27.
Lets do it:
81/3 = 27
So we have exactly enough for the 27 students.
Answer:
19/30
Step-by-step explanation:
If the probability of an event happening is 11/30, then you simply subtract 11 from 30 to find the remaining "possibilities"
30 - 11 = 19
So- this means that the probability of the event NOT happening, is...
19/30
Hope this helps!
