Westfalls is 7 miles south of edenville and Concord is 13 mile west of westfalls. What is the distance from edenville to Concord

Lelu [443]

Answer:

$D_x\approx14.8mile$

Step-by-step explanation:

From the question we are told that

Distance between Edenville and Westfalls $D_1=7$

Distance between Westfalls and Concord $D_2=13$

Generally the equation for Pythagoras is mathematically given by

$D_x^2=D_1^2+D_2^2$

$D_x^2=7^2+13^2$

$D_x=\sqrt{ 7^2+13^2}$

$D_x=14.76482306mile$

The distance b/w Edenville to Concord is

$D_x\approx14.8mile$

Three coins are flipped

RUDIKE [14]

Answer:

probability of getting no heads: 1/ 8

probability of at least two tails: 1/4

Step-by-step explanation:

To calculate the probability of getting no heads, multiply the probability of not getting heads for each coin. A coin has two sides: heads and tails; the probability of not getting heads would be 1/2.

1. Multiply the probabilities for each coin

1/2 · 1/2 · 1/2 = 1/8

To calculate the probability of getting at least two tails, multiply the probability of getting tails for two coins and the probability of flipping either heads or tails for the remaining coin. Because it is at least two tails, the remaining coin can flip to either heads or tails.

1. Multiply the probabilities for each coin

1/2 · 1/2 · 2/2 = 1/4

Write the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x y = -5.

Alik [6]

Y=2x-5 because parallel means keep the slope the same and the formula is y=mx+b b is y and y is -5 so your answer is y=2x-5

Richard’s store sells pineapples and grapefruits. Pineapples originally cost $5.15 apiece, and grapefruits originally cost $2.25

sveta [45]

Answer:

c. The price of grapefruits experienced a reduction 6.01 percentage points greater than the price of pineapples.

Step-by-step explanation:

The original price of Pineapples=$5.15

New price of Pineapples=$3.88

Find change in price of Pineapples

Change in price=original price- new price

$=5.15-3.88=1.27$

The price of Pineapple was reduced by $1.27

% reduction in price

(reduction value/original value) × 100

$=\frac{1.27}{5.15} *100=24.66$

=24.66%

The original price of grape fruits=$2.25

New price of grape fruits=$1.56

Change in price of grape fruit

Change in price= original price -new price

$=2.25-1.56=0.69$

% reduction in price of grape fruits

(reduction value/original value)×100

$=\frac{0.69}{2.25} *100=30.67$

=30.67%

Answers

The fruit that has its price reduced by a greater percentage is grape fruit

How many percentage points greater = 30.67%-24.66% = 6.01 points

Use the linear regression feature on a graphing calculator to find the correlation coefficient for the data. Round your answer t

Lerok [7]

Answer:

0.9769

Step-by-step explanation:

Given the data :

X : 7.5, 9.9, 4.8, 9, 8.1, 1.7, 3.1

Y : 35, 6, 45, 18, 20, 89, 84

The Correlation Coefficient obtained by using a graphing calculator to model the data above is : 0.9769, this means a strong positive correlation exists between the two variables.
