Answer:
<em>* Siobhan's profit at the grocery store ⇒ $ 10.8 *</em>
Step-by-step explanation:
See below;
Priya's 40% profit in the grocery store ⇒ 40/100 * 9 = 2/5 * 9 = 18/5 ⇒ $ 3.6,
Priya's profit at the grocery store ⇒ 9 + 3.6 ⇒ $ 12.6,
Siobhan's 15% of Priya's profit from the store ⇒ 15/100 * 12.6 = $ 1.8
Siobhan's profit at the grocery store ⇒ 12.6 - 1.8 = $ 10.8
<em>* Siobhan's profit at the grocery store ⇒ $ 10.8 *</em>
800 different sets of digits
Since the first digit is a factor of 20, the factors of 20 are 1,2,4,5,10,20. We only need the single digit factors which are 1,2,4 and 5. These 4 numbers can be permuted in 1 way for the first digit, so we have ⁴P₁.
For the second digit, we have 10 digits permuted in 1 way, ¹⁰P₁ and also for the third digit, we have 10 digits permuted in 1 way, ¹⁰P₁ and for the last digit, which is divisible by 5, it is either a 0 or 5, so we have two digits permuted in 1 way, ²P₁.
So, the number of different 4 digit number that Zara'2 4-digit PIN code could be is ⁴P₁ × ¹⁰P₁ × ¹⁰P₁ × ²P₁ = 4 × 10 × 10 × 2 = 800 different sets of digits
I believe the answer would be: 4+y<15
Answer:
Independent variable: C
Dependent Variable: M
Step-by-step explanation:
Lets begin with the Independent variable, C. C is moreover a result, so it remains as a dormant number that is yet to be known. M which is the dependent variable, contributes to the corresponding number we call the cost. When M , a quantity that is being manipulated the number 0.6, multiplies "per mile" plus 25. The actual expression is 25 + 0.6m, and the indpendent variable is known as the numerical coefficient.
