Lorraine threw a football 9.89 meters. Belinda threw the football 12.20 meters. How many meters farther did Belinda throw the football than Lorraine?

Answers

Answer:

Belinda threw the ball 2.31 meters farther than Lorraine.

Step-by-step explanation:

To find how many meters farther Belinda threw the ball, we subtract Belinda's distance from Lorraine's distance.

We have that:

Lorraine threw a football 9.89 meters.

Belinda threw the football 12.20 meters.

12.20 - 9.89 = 2.31

Belinda threw the ball 2.31 meters farther than Lorraine.

Suppose that mean retail price per gallon of regular grade gasoline is $3.45 with a standard deviation of $0.10 and that the retail

Lololo

b. What percentage of regular grade gasoline sells for between $3.35 and $3.65 per gallon (to 1 decimal)?

%

c. What percentage of regular grade gasoline sells for less than $3.55 per gallon (to 1 decimal)?

%

Answers

The percentage of regular grade gasoline sells for between $3.35 and $3.55 per gallon is 64%

The percentage of regular grade gasoline sells for between $3.35 and $3.65 per gallon is 81.5%

The percentage of regular grade gasoline sells for less than $3.55 per gallon is 84%

Given :

Mean retail price is $3.45

Standard deviation is 0.10

Empirical rule states that 99.7% of data is observed in normal distribution that lies within 3 standard deviations.

68% of data lies under 1 standard deviation

95% lies under 2 standard deviations

99.7% lies under 3 standard deviations

there are 3 standard deviations on the left and right of mean . The graph is attached below

Mean is 3.45. standard deviation is 0.1

3.45+0.1=3.55

3.45-0.1=3.35

So 3.35  and 3.55 lies under first standard deviation

The percentage between $3.35 and $3.55 is 68%

3.45 +0.1+0.1=3.65

3.35 lies on 1 standard deviation on left and 2 deviations on the right of mean

So , 34+34+13.5=81.5%

The percentage between $3.35 and $3.65 is 81.5%

For gasoline sells for less than 3.55 , there are 3 standard deviation on the left of mean and 1 standard deviation on the right

0.15+2.35+13.5+34+34=84%

Find 50% of 36:
Find 25% of 36:
Find 75% of 36:

Answers

Answer:

18, 9, 27

Step-by-step explanation:

36 ÷ 2 = 18. Dividing by 2 is the same as multiplying by 50%.

36 ÷ 4 = 9. Dividing by 4 is the same as multiplying by 25%.

Since 25% • 3 = 75%, you can do 9 (from previous) • 3 to get 27.

Angelo the Alligator is laying out next to a perfectly circular pond. He is 25 feet from the edge of the pond and 45 feet from the point of tangency. Determine the radius of the pond.

Answers

9514 1404 393

Answer:

  28 feet

Step-by-step explanation:

Let r represent the radius of the pond. Then the Pythagorean theorem gives us the relation ...

  (25+r)² = r² + 45²

  625 +50r +r² = r² +2025

  50r = 1400 . . . . . . . . . . . . . subtract r²+625 from both sides

  r = 28 . . . . . . . . . . . divide by 50

The radius of the pond is 28 feet.

Question 1: What is the solution to the system of equations? ( Look at the picture) Answer part A and Part B. ( Will Mark Brainliest). ​

Answers

Answer:

x-2y= -8

Step-by-step explanation:

Answer:

Step-by-step explanation: Part A:

3x−6y=−12;x−2y=−8

Rewrite equations:

x−2y=−8;3x−6y=−12

Step: Solvex−2y=−8for x:

x−2y=−8

x−2y+2y=−8+2y(Add 2y to both sides)

x=2y−8

Step: Substitute2y−8forxin3x−6y=−12:

3x−6y=−12

3(2y−8)−6y=−12

−24=−12(Simplify both sides of the equation)

−24+24=−12+24(Add 24 to both sides)

Rita charged $126 for a DVD player at an interest rate of 15.9%. How much will Rita have to pay for the DVD player after 3 years if she makes no payments?

Answers

Answer:

$ 129.34 will be the total payment made after two months if she made no initial payment

Step-by-step explanation:

annual interest rate = 15.9 %

initial charge = $126

to get the annual interest paid = 15.9% of $126

                                                  = 0.159 * $126 = $20.03

monthly interest paid would be = annual interest  / 12 months

                                                    = 20.03 / 12 = $1.67

hence in 2 months Rita will pay = initial charge + monthly interest * 2

                                                    = $126 + $ 1.67 *2 = $ 126 + $3.34

                                                    = $ 129 .34

Interest rates are always given an annual interest rate.

You have a bag with 10 pennies, 10 quarters, and 10 dimes. You draw 2 coins without replacement. Which action, performed before the draws, increases the probability of drawing 3 quarters in a row? O removing pennies and dimes from the bag O adding dimes to the bag O adding pennies to the bag o adding pennies and dimes to the bag ​

Answers

Answer:

Removing pennies and dimes from the bag

Step-by-step explanation:

From the beginning, we have a 1 in 3 chance of drawing a quarter. If we were to add dimes and/or pennies to the bag, this would make us more likely to draw a dime or a penny, and less likely to draw a quarter. Proportionally, we want the most quarters in the bag to get the highest probability of drawing a quarter from the bag.

What is a Fraction?

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Given that Jamal spent 1 1/2 hours studying for his science test, while Ruby studied for 1/3 the amount of time that Jamal studied. Therefore, we can write,

[tex]\rm \text{Time for which Ruby studied} = 1\dfrac12 \times \dfrac13\\\\\text{Time for which Ruby studied} = \dfrac32 \times \dfrac13 = \dfrac12\ hours[/tex]

Hence, the fraction of an hour for which Ruby studied is (1/2).
