Answer:
x=-2
y=-3
Step-by-step explanation:
-9x+4y = 6
9x+5y = -33
We will add these together to eliminate x
-9x+4y = 6
9x+5y = -33
----------------
0x +9y =- 27
9y = -27
Divide by 9
9y/9 = -27/9
y =-3
We still need to find x
9x +5y = -33
9x +5(-3) = -33
9x-15 = -33
Add 15 from each side
9x+15-15 =-33+15
9x=-18
Divide by 9
9x/9 = -18/9
x = -2
Answer:
<u>=14/15</u>
Step-by-step explanation:
distributive property: a(b+c)=ab+ac
product it's must be multiply the numbers, fractions, factors, and multiples.
3/5*14/9
you can also cross out the common factor of 3.
1/5*14/3
multiply the fractions.
1*14/5*3
1*14=14
14/5*3
5*3=15
<u>=14/15</u>
Hope this helps!
Thanks!
(A) 1.18*10^3
When you multiply by 10^3, that means you're moving the decimal 3 places to the right.
1.18 becomes <em>1,180</em>.
(B) 6.701*10^-2
When you multiply by a negative exponent, it moves the decimal to the left. 10^-2 moves the decimal 2 places to the left.
6.701 becomes <em>0.0671</em>
Answer:
Range is 44
mean is 29.7
variance is 289.56
standard deviation is 17.016
Step-by-step explanation:
The data given as follows
3, 24, 30, 47, 43, 7, 47,13, 44, 39
Range = maximum - minimum
= 47 -3 = 44
mean = 
= 297/10 = 29.7
variance = 
= 289.56
SD = 
= 17.016
The standard deviation of the given data is not a good measure as the range and standard deviation are far apart. The standard deviation gives how the given data is dispersed from the mean or expected value, while the range gives a rough idea of variability of the data.
