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:
t = 34.548
Step-by-step explanation:
Here X₁ = Solid values / n
= 26.3 +25.3+26.1+25.6+26.7+25.9/6
=155.9 / 6
=25.984
X₂ = Liquid values/n
= 16.9 +16.6+16.5+17.4+17.4+17.2 / 6
=102/6 = 17
Formula for the sample standard deviation is

we get
s₁ = 0.49967
s₂ = 0.3949
Construction of hypothesis
H₀ :μ₁ = μ₂
H₁ : μ₁ ≠ μ₂
Apply test statistic formula we get the value

putting all these values
t = 25.984 - 17 / √ (o.49967)²/6 + (0.39497)²/6
t = 34.548
Hope this helps...I couldn't give the exact answer in sig figs because you did not specify how many sig figs you wanted in the answer.
