21
therefore, CM + MQ = CQ
17 + MQ = 21
MQ = 21 - 17
MQ = 4 <===
Answer:
0.1513
Step-by-step explanation:
mean= 15.4
SD=4.5
P(20<X<28)
P((20-15.4)/4.5 < Z < (28-15.4)/4.5)
P(1.022 < Z< 2.8 )
From Z distribution table,
P(Z<2.8)= 0.99744
P(Z<1.022)= 0.84614
P(1.022 < Z< 2.8 )= P(Z<2.8)- P(Z<1.022)
= 0.99744-0.84614
= 0.1513
For first pound it is = $2.41
For next six, = 0.41 * 6 = $2.46
Remaining = 7.99 - (2.41 + 2.46) = 7.99 - 4.87 = 3.12
Now, additional pounds = 3.12 / 0.39 = 8
Total weight = 1 + 6 + 8 = 15
In short, Your Answer would be 15 pounds
Hope this helps!
Answer:
a)4x ≤30 where x is the quantity of muffins b) The greatest amount of muffins you can purchase is 7. c) 2dollars
Step-by-step explanation:
a) 4x ≤30 where x is the quantity of muffins
b) 4x≤30
x≤7.5
It means that you can buy only 7.5 muffins or less. But you can buy only whole muffin, so you can buy 7 muffins or less. The greatest amount of muffins you can purchase is 7.
c) If you purchase 7 muffins you spend 7*4= 28 dollars
And then you will have 30-28=2dollars
