Answer to question eight: $152.96

Step-by-step explanation:

$14.12 * 8 pages = $112.96

$0.20 * 200 words = $40

$112.96 + 40 = $152.96

Answer: 
Choice A
1/17; no, they are dependent events

============================================

Explanation:

There are 13 spades and 52 cards total. So 13/52 = 1/4 is the probability of drawing one spade

If we do not replace the card we pull out, then the probability of another spade is 12/51 since there are 12 spades left out of 51 total. 

Multiply the fractions 1/4 and 12/51 to get
(1/4)*(12/51) = (1*12)/(4*51) = 12/204 = 1/17

The two events are not independent because the second event (pulling out a second spade) depends entirely on what happens in the first event (pulling out a first spade). The fact that the probability is altered indicates we have dependent events.

Question 5: A car used 1164 gallon of gas to drive ya of a mile. At this rate, how many miles can the car travel using 1
Sergeu [11.5K]

Answer:

Hello! Your answer is BELOW

Step-by-step explanation:

Car will cover 16 miles in 1 gallon of the gas.

We can solve this question by unitary method.

∵ A car used \frac{1}{64} gallons of gas to drive the distance =  \frac{1}{4} miles

∴ Car used 1 gallons to drive the distance = \frac{1}{4} \\\\\frac{1}{64}

= \frac{64}{1}  X    \frac{1}{4}

= \frac{64}{4}

= 16 miles

Therefore, car will cover 16 miles in 1 gallon of the gas.

Hope I helped! Hope you make an 100%.

Choose the polynomial that is written in standard form. (1 point) Group of answer choices xy3 + 4x5y + 10x3 x4y2 + 4x2y + 8x −9x
Goryan [66]

Answer:

No polynomials are in standered form.

Step-by-step explanation:

Given polynmials are,

xy^3+4x^5y+10x^3\hfill (1)

x^4y^2+4x^2y+8x-9x^4y^2+4x^3y^5+10x^2\hfill (2)

x^6y^3+4x^4y^8+x^2\hfill (3)

To find the polynomial of two variable in standered form we have to write the sum of the degree of each exponent in descending or ascending order.

(1) xy^3+4x^5y+10x^3

where sum of degree of exponents are of the form,

Sum of (degree of x+ degree of y)=(1+3)\to (5+1)\to 3=4\to 6\to 3

which is not a descending order or ascending so it is not a standered form.

(2) x^4y^2+4x^2y+8x-9x^4y^2+4x^3y^5+10x^2

where sum of degree of exponents are of the form,

Sum of (degree of x+ degree of y)=(4+2)\to (2+1)\to (1)\to (4+2)\to (3=5)\to 2=6\to 3\to 1\to 6\to 8\to 2

which is not a descending or ascending order so it is not a standered form.

(3)  x^6y^3+4x^4y^8+x^2

where sum of degree of exponents are of the form,

Sum of (degree of x+ degree of y)=(6+3)\to (8+4)\to 2=9\to 12\to 2

which is not a descending or ascending order so it is not a standered form.
