3 x $37.25 = $111.75
$229.25 - $111.75 = $117.50
$117.50 ÷ 5 = $23.50
So the answer is B

Matthew made slightly larger blanket that was 8 Ft long. Its area is 64 sq ft what is its perimeter?

Andreas93 [3]

Answer:

32 ft

Step-by-step explanation:

Given data

Length= 8ft

Area= 64 f^2

Let us find the width

Area= Length*Width

64= 8* Width

Width= 64/8

Width= 8ft

Hence the perimeter= 2L+2W

P= 2*8+2*8

P= 16+16

P= 32 ft

The probability that a student has a Visa card (event V) is .63. The probability that a student has a MasterCard (event M) is .1

Aleksandr-060686 [28]

Answer:

a) The probability that a student has either a Visa card or a MasterCard is 0.71.

b) V and M are not independent.

Step-by-step explanation:

Given : The probability that a student has a Visa card (event V) is 0.63. The probability that a student has a MasterCard (event M) is 0.11. The probability that a student has both cards is 0.03.

To find :

a) The probability that a student has either a Visa card or a MasterCard ?

b) In this problem, are V and M independent ?

Solution :

The probability that a student has a visa card(event V) is P(V)= 0.63

The probability that a student has a MasterCard (event M) is P(M)= 0.11

The probability that a student has both cards is $P(V \cap M)=0.03$

a) Probability that a student has either a Visa card or a Master Card is given by,

$P(V \cup M) = P(V) + P(M) - P(V\cap M)$

$P(V \cup M) = 0.63+ 0.11- 0.03$

$P(V \cup M) =0.74- 0.03$

$P(V \cup M) =0.71$

The probability that a student has either a Visa card or a MasterCard is 0.71.

b) Two events, A and B, are independent if $P(A\cap B)=P(A)P(B)$

For V and M to be independent the condition is satisfied,

$P(V\cap M)=P(V)P(M)$

Substitute the values,

$0.03=0.63\times 0.11$

$0.03\neq 0.0693$

So, V and M are not independent.

What are the zeros of the function f(x)=x^2-2x-15?

valkas [14]

To find the zeros of this function, we must first set the entire function equal to 0

f(x) = x² - 2x - 15 = 0

Since this is a quadratic function, we must use the quadratic formula, which is:

$\frac{-b +/- \sqrt{b^{2} - 4(a)(c) } }{2a}$

Let's assign a, b, and c using our first function
x² means a = 1 (because it could be written as 1x²)
-2x means b = -2
-15 means c = -15

Now let's plug those in:

$\frac{-(-2) +/- \sqrt{(-2)^{2} - 4(1)(-15) } }{2(1)}$

which simplifies to:

$\frac{2 +/- \sqrt{(4 + 60} }{2}$

Simplified further:

$\frac{2 +/- \sqrt{(64} }{2}$
$\frac{2 +/- 8 }{2}$
And divide it by the 2 on the bottom gives us:

$2 +/- 4$

2+4 = 6
2-4 = -2

So the zeros of this function are -2 and 6
