_____________________________________________________
Explanation:
__________________________________________________________
From the graph attached, which is "linear", we have 75 minutes (x-axis);
corresponding to 30 km (y-axis);
__________________________________________________________
We notice that all the answer choices are given in units of:
______________________________________________________
→ "km/min" ; that is, "kilometers per minute" ;
______________________________________________________
→ So, 30 km / 75 min = (30/75) km/ min = ? km / min ;
______________________________________________________
→ (30/75) = (30÷15) / (75÷15) = ⅖ km/min ; or 0.4 km/min ;
______________________________________________________
→ or; use calculator: (30/75) = (30÷75) = 0.4 km/min ;
______________________________________________________
→ which corresponds to:
______________________________________________________
→ Answer choice: [B]: 0.40 km/min .

Answer:

August made the recipe using the incorrect ratio

Step-by-step explanation:

* Lets explain how to solve the problem

- Sally's recipe is a combination of lemonade and fruit

- Sally uses 6 cups of lemonade for every 8 cups of fruit

∵ Sally uses 6 cups of lemonade for every 8 cups of fruit

∴ The ratio of sally recipe is 6 : 8

- Simplify the terms of the ratio by divide them by 2

∴ The ratio of sally recipe is 3 : 4

- August made a recipe with 35 cups of liquid total

- He made 15 cups of them lemonade

∵ The total number of cups August made is 35

∵ 15 of them are lemonade

∴ The number of fruit cups = 35 - 15 = 20 cups

∵ August mad 15 cups of lemonade for every 20 cups of fruit

∴ The ratio of August recipe is 20 : 15

- Simplify the terms of the ratio by divide them by 5

∴ The ratio of August recipe is 4 : 3

∵ The ratio of Sally recipe is 3 : 4

∵ The ratio of August recipe is 4 : 3

∵ The ratio 3 : 4 ≠ the ratio 4 : 3

∴ August made the recipe using the incorrect ratio

What is the best estimate for the sum of 3/4 and 1/12

TEA [102]

Well first you would find a common denominator which would be 1w and then since you multiplied 4 by 3 to get to 12 you multiply 3 by 3 which is 9. So then you would have 9/12 + 1/12 which = 10/12

Over [174]

Answer:

Population : all the steaks Tessa can cook

Parameter : minimum internal temperature of 160 degrees Fahrenheit

Sample : two random thermometer readings

Statistic : minimum sample reading of 165 degrees Fahrenheit

Step-by-step explanation:

Let's recall the definitions of these statistical concepts and match it with the information that were provided to us:

Populations can be the complete set of all similar items that exist, in our case, all the steaks that Tessa can cook.
Parameter is is a value that describes a characteristic of an entire population, such as the minimum temperature of the steaks Tessa is cooking in Fahrenheit degrees.
Sample is a subset of the population, in our case, the two random readings of the thermometer Tessa did.
Statistic is a characteristic of a sample, for our problem, it's the minimum reading of 165 degrees Fahrenheit.
