1st find rate from the given

D = RT

315 = 5R

63 = R miles/hour so,

then find distance for 7 hours

D = RT

D = 63 * 7

D = 441

3. If mZEFH = (5x + 1), mZHFG = 62°, and<br> mZEFG = (18x + 11), find each measure.

arsen [322]

Answer/Step-by-step explanation:

Given:

m<EFH = (5x + 1)°

m<HFG = 62°

m<EFG = (18x + 11)°

Required:

1. Value of x

2. m<EFH

3. m<EFG

SOLUTION:

1. Value of x

m<EFH + m<HFG = m<EFG (angle addition postulate)

(5x + 1) + 62 = (18x + 11)

Solve for x using this equation

5x + 1 + 62 = 18x + 11

5x + 63 = 18x + 11

Subtract 18x from both sides

5x + 63 - 18x = 18x + 11 - 18x

-13x + 63 = 11

Subtract 63 from both sides

-13x + 63 - 63 = 11 - 63

-13x = -52

Divide both sides by -13

-13x/-13 = -52/-13

x = 4

2. m<EFH = 5x + 1

Plug in the value of x

m<EFH = 5(4) + 1 = 20 + 1 = 21°

3. m<EFG = 18x + 11

m<EFG = 18(4) + 11 = 72 + 11 = 83°

Consider a bag that contains 218 coins of which 6 are rare Indian pennies. For the given pair of events A and B, complete parts

Afina-wow [57]

Answer: (a) Independent events , (b) 0.00075

Step-by-step explanation:

Since we have given that

Number of coins = 218

Number of rare Indian pennies = 6

Let Event A: When one of the 218 coins is randomly selected, it is one of the 6 Indian pennies.

Event B : When another one of the 218 coins is randomly selected (with replacement), it is also one of the 6 Indian pennies.

As we know that

$P(A)=\dfrac{6}{218}=0.0275\\\\and\\\\P(B)=\dfrac{6}{218}=0.0275$

(a) so, they are independent events as there is a condition of 'with replacement'.

(b) P(A and B) is given by

$P(A\cap B)=P(A).P(B)=0.0275\times 0.0275=0.00075$

Hence, (a) Independent events , (b) 0.00075
