Answer:

16-[tex]x^{2}[/tex]

Step-by-step explanation:

Take the area of the whole square (4x4=16) and subtract the area of the smaller square ([tex]x^{2}[/tex])

Answer:

Step-by-step explanation:

we can start with process of elimanation.

f) wrong. this is because 12 is the second smallest number out of the four with ranch being the smallest with 8.

g) wrong. this is because 8x2=16, which means its not twice as likely it would end up. being more than twice as likely.

h) wrong. all of these numbers are different, so are smaller and bigger than others, so the rate of probability is going to be different for each chip type.

j) right. this is because if we do 8x2=16, that is still smaller than 20 so it is MORE than 2x as likely since 20 is a greater number than 16.

CORRECT ANSWER: J.

hope this helped!!

The statement which best supported is J) The flavor is more than twice as likely to be cheese as it is to be ranch.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Total number of chips = 12 + 18 + 8 + 20 = 58

Probability of finding Plain chips = 12/58 = 0.2069

Probability of finding Jalapeno chips = 18/58 = 0.3103

Probability of finding Ranch chips = 8/58 = 0.1379

Probability of finding Cheese chips = 20/58 = 0.3448

The flavor is least likely to be Ranch, not plain.

Twice the probability of Ranch = 0.2759

Hence the correct option is The flavor is more than twice as likely to be cheese as it is to be ranch.

Step-by-step explanation:

The percent decrease in Julia's monthly driving would be 35.9%. This is calculated by taking the difference between the two months (120 - 78 = 42) and dividing it by the initial amount (120) and then multiplying the result by 100. (42/120)*100 = 35.9%.

I want to know about exponent and surds

Explanation:

Let's rewrite each given fraction with a common denominator of 5*7 = 35.

1/5 = (1/5)*(7/7) = 7/35

1/7 = (1/7)*(5/5) = 5/35

Then we can see that 6/35 is between 5/35 and 7/35, since 6 is between 5 and 7.

Put another way:  5/35 < 6/35 < 7/35 since 5 < 6 < 7

This then means 1/7 < 6/35 < 1/5

Therefore, Maria's claim is incorrect.

Answer:

A) -$1,275/yr

Step-by-step explanation:

The value of the car in 2015 was a third of its original value in 2006, which means that the value of the car decreased by 2/3.

To find the rate of change, we can use the formula:

rate of change = (final value - initial value) / (time elapsed)

In this case, the initial value is $28,350, the final value is a third of that value, which is $28,350 * (2/3) = $18,900. The time elapsed is 2015 - 2006 = 9 years.

So the rate of change is:

rate of change = ($18,900 - $28,350) / 9 = -$9,450 / 9 = -$1,050/yr

Therefore, the rate of change in the value of the car from 2006 to 2015 is -$1,050/yr.

The correct option is A) -$1,275/yr

The rate of change in the value of the car from 2006 to 2015 is -$1,800/yr, the correct option is D

The average Rate of Change of the function f(x) can be calculated as;

[tex]f(x) = \dfrac{f(b) - f(a)}{b-a}[/tex]

f(x) represents the function x

Given;

Its worth in 2006= $28,350

In 2015 it was worth a third of its original value

Now,

Car value in 2015= 1/3 x 28,350

=9450

Number of years from 2006 to 2015

=8

Rate of change in value per year= 9450/8

=1181

Therefore, the rate of change will be -$1,800/yr
