A recipe calls for 5 1/2 cups of flour. Molly only has 3 3/4 cups of flour. Write and solve an equation to find the additional a

Leni [432]

Answer:

1 3/4 cups

Step-by-step explanation

Since the recipe calls for 5 1/2 cups of flower and Molly only has 3 3/4 cups, subtract 3 3/4 from 5 1/2 to get the remaining cups of flour needed to make the recipe.

5 1/2 - 3 3/4 = 1 3/4

Two weeks in a row, the golf course hosts a group of golfers. The second week had 10 more golfers than the first week. Use the d

Trava [24]

Answer:

Option A.

Step-by-step explanation:

From the first dot plot the given data set for week 1 is

62, 68, 68, 68, 69, 70, 70, 72, 72, 72, 75, 75, 76, 78, 78, 80, 80, 80, 89, 89

Divide the data in 4 equal parts.

(62, 68, 68, 68, 69), (70, 70, 72, 72, 72), (75, 75, 76, 78, 78), (80, 80, 80, 89, 89)

$Range=Maximum-Minimum=89-62=27$

$Median=\frac{72+75}{2}=73.5$

$Mean=\frac{\sum x}{n}=\frac{1491}{20}=74.55$

From the second dot plot the given data set for week 2 is

62, 68, 68, 68, 69, 70, 70, 72, 72, 72, 75, 75, 76, 78, 78, 80, 80, 80, 85, 86, 86, 86, 88, 88, 88, 88, 89, 89, 89, 89

Divide the data in 4 equal parts.

(62, 68, 68, 68, 69, 70, 70), 72, (72, 72, 75, 75, 76, 78, 78), (80, 80, 80, 85, 86, 86, 86), 88, (88, 88, 88, 89, 89, 89, 89)

$Range=Maximum-Minimum=89-62=27$

$Median=\frac{78+80}{2}=79$

$Mean=\frac{\sum x}{n}=\frac{2364}{30}=78.8$

The range for Week 1 is equal to the range for Week 2.

The median for Week 2 is more than the median for Week 1.

The mean for Week 2 is more than the mean for Week 1.

Therefore, the correct option is A.

Solve for y, 12x-20y=180

nydimaria [60]

Answer:

y=35x−9

Step-by-step explanation:

Step 1: Add -12x to both sides.

12x−20y+−12x=180+−12x

−20y=−12x+180

Step 2: Divide both sides by -20.

−20y−20=−12x+180−20

y=35x−9
