1) Debbie has $93 saved up to buy a PS4 on Black Friday. On Black Friday the PS4 will cost $150 dollars, if Debbie babysits and earn two dollars everyday she babysits, how many days left does she have until she can buy the PS4?
2n+93=150
2n=150-93
2n=57
n=
2) What does P equal? P stands for the amount of apples needed for a pie sale. We also need to find Q, which is how much peaches we'll need as well, because it is a peach and apple pie sale.
-----------------------------------------
pq=7*10
pq=70
Hope this helps, have a BLESSED and wonderful day! :-)

Answer:
The mean of the distribution of heights of students at a local school is 63 inches and the standard deviation is 4 inches.
Step-by-step explanation:
The normal curve approximating the distribution of the heights of 1000 students at a local school is shown below.
For a normal curve, the mean, median and mode are the same and represents the center of the distribution.
The center of the normal curve below is at the height 63 inches.
Thus, the mean of the distribution of heights of students at a local school is 63 inches.
The standard deviation represents the spread or dispersion of the data.
From the normal curve it can be seen that values are equally distributed, i.e. the difference between two values is of 4 inches.
So, the standard deviation is 4 inches.
Answer:
12
Step-by-step explanation:
Well, to make things easier, we can first note that 24/4 is equal to 6. This helps because integers are easier to work with compared to fractions. Next, multiplying 2 by 6, we get 12.
4^4square root 2 is the answer
