Answer:
- City A was the warmest
- City B was the coolest
Step-by-step explanation:
If we list the temperatures from lowest to highest, they are 58, 60, 64, 68. The highest temperature was the warmest. It was recorded in City A.
The lowest temperature was the coolest. It was recorded in city B.
City A was the warmest; city B was the coolest.
Answer: the equations are
0.02x + 0.07y = 156
y = 300 + x
Step-by-step explanation:
Let x represent the total dollar amount of phone sales that she makes.
Let y represent the the total dollar amount of computer sales that she makes.
Josiah earns a 2% commission on the total dollar amount of all phone sales he makes, and earns a 7% commission on all computer sales. She earned a total of $156 in commission. This means that
0.02x + 0.07y = 156 - - - - - - - - - - -1
Josiah had $300 more in computer sales than in phone sales. This means that
y = 300 + x
The mode is 4 and 9 (if two different numbers appear twice then they are both the mode)
The median is 4 as it is the middle number (put the numbers in order to find this out and cancel each number out from both sides, if there are two numbers left add them both and divide by two)
The mean is 4.3 because if you add them all up and divide by how many there are then you will get 4.285. Round this to one decimal point and 4.3 should be the answer. Mean is another word for average
From all the information given, you're going to have to create two equations and solve accordingly.
If x=cost for one day at hotel; and y=cost for one day at amusement park then,
eq1 : 450=3x+2y ; eq2: 700=5x+3y
The total cost of the trip will be number of days spent at each location multiplied by the cost.
If you multiply equation 1 by 3 and equation 2 by 2 and subtract equation 2 from 1, than you will be able to isolate x.
1400=10x+6y
1350=9x+6y
x=$50; then plug back into any equation to find y.
450=3*50 + 2y
y=$150
Answer:
0+7i
Step-by-step explanation:
![\sqrt{-49}=\sqrt{49}\sqrt{-1}=7i=\boxed{0+7i}](https://tex.z-dn.net/?f=%5Csqrt%7B-49%7D%3D%5Csqrt%7B49%7D%5Csqrt%7B-1%7D%3D7i%3D%5Cboxed%7B0%2B7i%7D)
The real part of the expression ('a') is zero. We have shown that, so it will be in the required form. Ordinarily, 0 would not be shown when writing this number.

We have taken the question to mean the principal square root. -7i is also a root of -49.
