Given :

Two numbers 25 and 17.

How much larger is the sum of the numbers 25 and 17 compared to their difference? (Two small brackets will be used.)

To Find :

How much larger is the sum of the given numbers as compared to their difference.

Solution :

Sum of given numbers, S = 25 + 17 = 42 .

Difference of given numbers, D = 25 - 17 = 8 .

The difference between S and D is, S - D = 42 - 8 = 34 .

Therefore, sum of the numbers is larger by 34 than in difference.

Write the equation of a line, in SLOPE INTERCEPT FORM, that is perpendicular to the given equation and passes through the given

adoni [48]

Step-by-step explanation:

slope interception formula is

y-y1=m(x-x1)

where m is m=y-y1/x-x1 in this case m=-2 because the line we are trying to find is parallel to the given one y=-2x-6 where slope k=-2

so the final equation would be

y-1=-2(x-(-4))

y-1=-2x-2*4

y=-2x-8+1=-2x-7

Is it possible to construct a triangle with the given lengths? 17, 37, 53

kvv77 [185]

Answer:

Yes

Step-by-step explanation:

In any triangle, the sum of any two sides must be larger than the third side. To test this, we only actually need to pick the two shorter sides. In this case, the following inequality is true:

$17+37>53,\\54>53,\\\text{True}\:\checkmark$

Can u guys PLEASE explain the difference between 2 x 10 to the power of 4 and 2 to the power of 4

Alexxx [7]

Answer:

see explanation

Step-by-step explanation:

2 × $10^{4}$

= 2 × 10 × 10 × 10 × 10

= 2 × 100 × 100

= 200 × 100

= 20000

And

$2^{4}$

= 2 × 2 × 2 × 2

= 4 × 4

= 16

Write a polynomial function in standard form with zeros at 1, 2, and 3.

nadezda [96]

The polynomial whose zeroes are 1, 2 and 3 is given by,
(x-1)(x-2)(x-3) = 0
(x-1)[x²-3x-2x+6]=0
(x-1)[x²-5x+6]=0
x[x²-5x+6] -1[x²-5x+6]=0
x³-5x²+6x-x²+5x-6=0
x³-6x²+11x-6=0

Therefore, the required polynomial is,
x³ - 6x² + 11x -6 = 0

1500 customers hold a VISA card; 500 hold an American Express card; and, 75 hold a VISA and an American Express. What is the pro

alex41 [277]

Answer:

There is 15% probability that a customer chosen at random holds a VISA card, given that the customer has an American Express card.

$P(VISA \:| \:AE) = 15\%\\$

Step-by-step explanation:

Number of customers having a Visa card = 1,500

Number of customers having an American Express card = 500

Number of customers having Visa and American Express card = 75

Total number of customers = 1,500 + 500 = 2,000

We are asked to find the probability that a customer chosen at random holds a VISA card, given that the customer has an American Express card.

This problem is related to conditional probability which is given by

$P(A \:| \:B) = \frac{P(A \:and \:B)}{P(B)}$

For the given problem it becomes

$P(VISA \:| \:AE) = \frac{P(VISA \:and \:AE)}{P(AE)}$

The probability P(VISA and AE) is given by

P(VISA and AE) = 75/2000

P(VISA and AE) = 0.0375

The probability P(AE) is given by

P(AE) = 500/2000

P(AE) = 0.25

Finally,

$P(VISA \:| \:AE) = \frac{P(VISA \:and \:AE)}{P(AE)}\\\\P(VISA \:| \:AE) = \frac{0.0375}{0.25}\\\\P(VISA \:| \:AE) = 0.15\\\\P(VISA \:| \:AE) = 15\%\\$

Therefore, there is 15% probability that a customer chosen at random holds a VISA card, given that the customer has an American Express card.
