Answer:
B. 5(4x+2y)-y
Step-by-step explanation:
Bring the 5 over and multiply
5×4 = 20 + x
=20x (thats the beginning of the expression)
5×2 = 10
10y - y = 9 because the - y is basically telling you to get rid of one of the y values so 10 - 1 = 9y
Answer:
20+24= 2(10+12) = 4(5+6)
Those are two ways to factor 20+24.
Answer:
Event not unlikely
Step-by-step explanation:
Probability is defined as the likelihood of an event occurring.

Total outcome,
=Total responses record which is:


Therefore the probability of 4+ phones is

Since
, the event is not unlikely
Step-by-step explanation:
Since, f(x) is a cosine function, it is periodic.
<u>Maximum : ( - 1 + </u><u>10<em>k</em></u><em><u> </u></em><u>, 28)</u> ; where <em>k</em> belongs to <em>Z</em>
Minimum : (4 + 10<em>k</em> , 22)
<u>Cycle No. 1</u> : k = 1
(A) The first occurrence of highest temperature in the cycle is on <u>day 9</u> after June 1 i.e. ( <u>June 10</u>) with <u>28 °C</u>.
<u>Cycle No. 1</u> : k = 0
(B) The first occurrence of lowest temperature in the cycle is on <u>day 4</u> ( <u>June 15</u>) with <u>22 °C</u>.
Putting the expression in same number into both expression should yield the same answer if they are equivalent.
