Answer:
<h2>11.25min</h2>
Step-by-step explanation:
In this problem, we first need to find the rate at which syn burns calories per minute
so in 15mins, he burns 200 calories
in 1 mins he will burn x
x= 200/15
x=13.33 calories per min this is the rate
So in one minute he will burn 13.33 calories
Now using the idea of rate=quantity/time
the rate=13.33
quantity=15 calories
time=?
time=quantity/rate
time=150/13.33
time=11.25min
Alternatively
(very fast approach)
if syn spend 15min to burn 200 cal
then he will spend x min to burn 150 cal
cross multiply
x=(150*15)/200
x=2250/200
x=11.25mins
Answer:
Step-by-step explanation:
The possible outcomes include 1, 2, 3, etc., up through 25. This in itself is insufficient to specify who will go first. There must be some further criteria.
Suppose each player chooses and announces a number from this set by writing it down on a scrap of paper which is placed face-down on the table. The person who chooses the smaller number goes first. Or, the person who chooses the larger number goes first.
The answer is C. You pay $128 in the third hour for both. Hope this helped
Answer:
x = -2 and y = 3
Step-by-step explanation:
It is given that,
4x + 5y = 7 -----(1)
3x – 2y = –12 ----(2)
<u>To find the value of x and y</u>
eq(1) * 3 ⇒
12x + 15y = 21 ----(3)
eq(2) * 4 ⇒
12x - 8y = -48 ---(4)
eq(3) - eq(4) ⇒
12x + 15y = 21 ----(3)
<u>12x - 8y = -48 </u> ---(4)
0 + 23y = 69
y = 69/23 = 3
Substitute the value of y in eq(1)
4x + 5y = 7 ----(1)
4x + 5*3 = 7
4x = 7 - 15 = -8
x = -8/4 = -2
Therefore x = -2 and y = 3
Answer:

And i fwe look into the normalstandar dtable we can find the desired probability:

And then the The area to the right of z = 1.51 is 0.0655
Step-by-step explanation:
For this case we want to find the following probability:

And for this case we can use the normal standard distribution and the complement rule and we have this:

And i fwe look into the normalstandar dtable we can find the desired probability:

And then the The area to the right of z = 1.51 is 0.0655
