Answer:
3.75 + 0.15n ≤ 5.25
Step-by-step explanation:
You can not spend more than $5.25 so the inequality sign must be less than or equal to
If you know the shop charges a minimum of $3.75 for a sandwich, you need to include that in your equation
The $0.15 for additional toppings is included as $0.15 multiplied by n (0.15n)
n can be from 0-10, as 10 is the most toppings you can get before you go over your spending limit and you don't have to pay for additional toppings if you don't want to.
The perimeter =14 in
The area =64cm
They are terms<span> that contain the same variables raised to the same power. Only the numerical coefficients are different. In an expression, only </span>like terms<span> can be combined. We combine </span>like terms<span> to shorten and simplify algebraic expressions, so we can work with them more easily.</span>
Answer:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
Step-by-step explanation:
A confidence interval of a proportion p% at the x% level with m% margin of error means that:
We are x% sure that the true mean of the population is in the interval from (p-x)% to (p+x)%.
In this problem, we have that
90% confidence level
44% with a margin of error of 2%
So:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
