Answer:
Step-by-step explanation:
Let's identify what we are looking for in terms of variables. Sandwiches are s and coffee is c. Casey buys 3 sandwiches, which is represented then by 3s, and 5 cups of coffee, which is represented by 5c. Those all put together on one bill comes to 26. So Casey's equation for his purchases is 3s + 5c = 26. Eric buys 4 sandwiches, 4s, and 2 cups of coffee, 2c, and his total purchase was 23. Eric's equation for his purchases then is 4s + 2c = 23. In order to solve for c, the cost of a cup of coffee, we need to multiply both of those bolded equations by some factor to eliminate the s's. The coefficients on the s terms are 4 and 3. 4 and 3 both go into 12 evenly, so we will multiply the first bolded equation by 4 and the second one by -3 so the s terms cancel out. 4[3s + 5c = 26] means that 12s + 20c = 104. Multiplying the second bolded equation by -3: -3[4s + 2c = 23] means that -12s - 6c = -69. The s terms cancel because 12s - 12s = 0s. We are left with a system of equations that just contain one unknown now, which is c, what we are looking to solve for. 20c = 104 and -6c = -69. Adding those together by the method of elimination (which is what we've been doing all this time), 14c = 35. That means that c = 2.5 and a cup of coffee is $2.50. There you go!
Answer:
It's a bit unclear with the table this way, but I count fifteen points, fifteen lines of the table, each a pair of numbers.
That's 15 degrees of freedom in the data. When modeling, each parameter in the model uses up one degree of freedom, so you'd use a smaller number of degrees of freedom when calculating t statistics, etc.
Answer:
Apple crisp has 10 grams of sugar per serving.
Greek frozen yogurt has 5grams of sugar per serving.
The recipe with the least amount of sugar per serving is the Greek frozen yogurt.
Step-by-step explanation:
Hi, to answer this question we have to divide the amount of grams of sugar by the number of servings for each case.
Apple crisp: 80 grams ÷8 servings =80 /8 = 10 grams of sugar per serving.
Greek frozen yogurt: 60 grams ÷12 servings =60 /12 = 5 grams of sugar per serving.
So, in conclusion:
Apple crisp has 10 grams of sugar per serving.
Greek frozen yogurt has 5grams of sugar per serving.
The recipe with the least amount of sugar per serving is the Greek frozen yogurt, because 5<10.
U didn’t give us the options soooo uhhhh C
