Step-by-step explanation:
3.5 hours for 1 cake means 3.5 hours per cake.
similar : 2 hours for 1 pie means 2 hours per pie.
so, if there are e.g. 3 pies, they take 3×2 = 6 hours.
therefore the general constraint is
3.5x1 + 2x2 <= 70
I think the names "x1" and "x2" are confusing when writing this inequality.
I prefer to use x and y.
and then it would look like
3.5x + 2y <= 70
Answer:
Step-by-step explanation:
We would use the t- distribution.
From the information given,
Mean, μ = 2950
Standard deviation, σ = 115
number of sample, n = 25
Degree of freedom, (df) = 25 - 1 = 24
Alpha level,α = (1 - confidence level)/2
α = (1 - 0.98)/2 = 0.01
We will look at the t distribution table for values corresponding to (df) = 24 and α = 0.01
The corresponding z score is 2.492
We will apply the formula
Confidence interval
= mean ± z ×standard deviation/√n
It becomes
2950 ± 2.492 × 115/√25
= 2950 ± 2.492 × 23
= 2950 ± 57.316
The lower end of the confidence interval is 2950 - 57.316 =2892.68
The upper end of the confidence interval is 2950 + 57.316 = 3007.32
The solution is correct.
8 x 12 = 96 sq ft
<span>4 x 8 = 32 sqft </span>
<span>96 / 32 = 3 panels </span>
<span>3 x 4 = 12 panels. I'm not sure which answer that would be. :-( If any, I would select C.) 6 panels. </span>
Answer:
False
Step-by-step explanation:
36% of 15120 =
36% * 15120 = 36/100 * 15120 = 36 *
false 36% of 15120 is 544.32
Answer:
7x-48
Step-by-step explanation:
we want our equation to look something like this
y=mx+b
let's start by solving for m (the slope) using the slope formula

Which means, so far, our equation looks like this
y=7x+b
now we just need to solve for B
We can do this by plugging in a set of coordinates
-6=7*6+b
-6=42+b
-48=b
which means our equation is
7x-48
