I don't know if there are any options....so I did reasearch I found the question and I believe it is graph 4 because it intersects at (1,5)!
Answer:
1x+ 1y =11
10x + 5y = 80
x = the cost of a taco = $5
y = the cost of a burrito = $6
Step-by-step explanation:
x = the cost of a taco
y = the cost of a burrito
1x+ 1y =11
10x + 5y = 80
rearange 1st equation as y = 11 -x and plug in into the 2nd one for y:
10x + 5( 11-x) = 80 distribute left side
10x + 55 - 5x = 80 combine like terms
10x - 5x = 5x
5x + 55 = 80 subtract 55 from both sides
5x = 80 - 55
5x = 25 divide by 5
x = 5
plug in for y in 1st equation y = 11--x =11-5 = 6
Answer:
There is a 82% probability that th esample mean annual sales per square foot is at least $384.
Step-by-step explanation:
We have a population with mean 390 and standard deviation 45.83.
Samples of size n=49 are taken.
The parameters of the sampling distribution are:
First, we have to calculate the z-score that satisfies:
This z-score, looked up in a standard normal distribution table, is z=-0.915.
Then, we can calculate the sample mean as:
There is a 82% probability that th esample mean annual sales per square foot is at least $384.
Answer:
y=5
Step-by-step explanation:
First, distribute the 2 to the 3y and -7
6y - 14 = 16
Second, add 14 to both sides.
6y = 30
Third, divide both sides by 6
y = 5
As you can see y equals 5!
I hope the explanation helped and have a great day!
Answer:
$6
Step-by-step explanation:
she has $8 now
her parents let her earn $5
so you have to take the $5 from the $8
so $8 - $5 = 3
and she had spent half her allowance so you have to double the $3
$3 * 2 = $6
she has a weekly allowance of $6
