Answer : 30
Reason : bc 5 x 6 = 30
Hmm
what you do is try to eliminate 1 variable in 2 equaions first
we can elminate x's in first and 2nd equation
add first and 2nd equation
x+3y-2z=10
<u>-x-2y+z=-7 +</u>
0x+y-z=3
y-z=3
multiply 2nd equation by 3 and add to last one
-3x-6y+3z=-21
<u>3x+9y-5z=28 +</u>
0x+3y-2z=7
3y-2z=7
we now have
y-z=3
3y-2z=7
multiply first equation by -2 and add to 2nd
-2y+2z=-6
<u>3y-2z=7 +</u>
y+0z=1
y=1
now we can sub back
y-z=3
1-z=3
minus 1
-z=2
times -1
z=-2
sub baack into any equation
x+3(1)-2(-2)=10
x+3+4=10
x+7=10
minus 7
x=3
x=3
y=1
z=-2

Keep in mind you would need a total of 120 ounces.
A: Corn cereal comes in 12 oz boxes and the person used 5 boxes, thus taking 60 oz away from the total, leaving 60 oz. Next, you’d have to divide 60 oz by 4 (since that’s how many boxes of wheat cereal were used). Resulting in a wheat box being worth 15 ounces!!
B: 12c+ 15w= 120 (c= corn cereal, w= wheat cereal)
C: 5 boxes of corn cereal with 4 boxes of wheat cereal; 0 boxes of corn cereal with 8 boxes of wheat cereal; 10 boxes of corn cereal with 0 boxes of wheat cereal.
Answer:
the lowest passing score would be x = 298
Step-by-step explanation:
School wishes that only 2.5 percent of students taking test pass
We are given
mean= 200,
standard deviation = 50
We need to find x
The area under the curve can be found by:
2.5 % = 0.025
So, 1- 0.025 = 0.975
We need to find the value of z for which the answer is 0.975
Looking at the z-score table, the value of z is: 1.96
Now, using the formula:
z = x - mean/standard deviation
1.96 = x - 200/50
=> 1.96 * 50 = x-200
98 = x - 200
=> x = 200+98
x = 298
So, the lowest passing score would be x = 298
So since you have a lot of numbers in your paragraph I think you’re gonna have to do some type of equation or are you just have to show your work because You have to show your work to define as what value
Because that is like the right function and a graph is a horizontal asked about so if you were moved its discount Tilly
