Answer:
$17.28.
Step-by-step explanation:
In the expression, d represents the number of drinks she orders and t represents the number of toppings.
In this case, she orders 4 drinks and 3 toppings, so d = 4 and t = 3.
0.90(2.25d + 1.40t + 6)
= 0.9(2.25 * 4 + 1.4 * 3 + 6)
= 0.9(9 + 4.2 + 6)
= 0.9 * 19.2
= 17.28
So, the total cost for Lindy and her friends will be $17.28.
Hope this helps!

Answer:
Step-by-step explanation:
I assume you are talking about square roots when you say root...
Sqrt(-9) = 3i
Sqrt(-12) = 2Sqrt(3)i
Complex number is 3 + 2Sqrt(3) i
Answer:
Step-by-step explanation:
a) The null hypothesis states that
The production line operation fills cartons with laundry detergent to a mean weight of 32 ounces.
H0 : µ = 32
The alternative hypothesis states that
The production line operation overfills or under fills cartons with the laundry detergent to a mean weight of above or below 32 ounces.
Ha : µ ≠ 32
b) when the calculations are done and the p value is determined, then it would be compared with the level of significance
When the significance level is lesser than the p value, we do not reject H0 because there is no sufficient evidence to conclude that the production line operation overfills or under fills cartons.
c) When the significance level is greater than the p value, we would reject H0 because there is sufficient evidence to conclude that the production line operation overfills or under fills cartons.
2y - 3y + y = 0
-y + y = 0
0 = 0
Hence, y has infinite possibilities of value since the equation is true without there being any use of y in it.
Hence, y could be any value.<span />
