geniusboy [140]

Answer:

0.995 P(at least 2) = 1 – P(X = 0) – P(X=1)

1 – 15C0 * 0.40 *0.615- 15C1*0.41*0.614

1 – 0.0000 – 0.005

= 0.995

Connor has a collection of dimes and quarters with a total value of $6.30. The number of dimes is 14 more than the number of qua
Anarel [89]

Connor has 14 quarters and 28 dimes.

Step-by-step explanation:

Given,

Worth of coins = $6.30 = 6.30*100 = 630 cents

We know that,

1 quarter = 25 cents

1 dime = 10 cents

Let,

Quarter = x

Dime = y

According to given statement;

25x+10y=630    Eqn 1

The number of dimes is 14 more than the number of quarters

y = x+14    Eqn 2

Putting value of y from Eqn 2 in Eqn 1

25x+10(x+14)=630\\25x+10x+140=630\\35x=630-140\\35x=490

Dividing both sides by 35

\frac{35x}{35}=\frac{490}{35}\\x=14

Putting x=14 in Eqn 2

y=14+14\\y=28

Connor has 14 quarters and 28 dimes.

Gnoma [55]
13x+6y = -30................y = -5 -13x/6
x−2y=−4...................... y = x/2 +2 <span>

If we graph both lines we can get the solution of the system (point of intersection)

The best estimate is (x,y) = (-2.625, 0.688)</span>
