A student says that the function shown by the table below can be represented by the rule y=x2-1. Describe and correct the error

Answer:

[tex]\mathbf{x=\frac{1}{2}}[/tex] is the solution to the equation: [tex]4x+12-8x=-1+2x+10[/tex]

The statement is true.

Option A is correct.

Step-by-step explanation:

We need to determine if [tex]x=\frac{1}{2}[/tex] is the solution to the equation: [tex]4x+12-8x=-1+2x+10[/tex]

Solving the equation first to find value of x

[tex]4x+12-8x=-1+2x+10[/tex]

Combining like terms:

[tex]4x-8x+12=2x+10-1\\-4x+12=2x+9[/tex]

Subtracting 2x on both sides

[tex]-4x+12-2x=2x+9-2x\\-4x-2x+12=9\\-6x+12=9[/tex]

Now, subtracting 12 on both sides

[tex]-6x+12-12=9-12\\-6x=-3\\[/tex]

Divide both sides by -6

[tex]\frac{-6x}{-6}=\frac{-3}{-6}\\x=\frac{1}{2}[/tex]

So, we get  [tex]\mathbf{x=\frac{1}{2}}[/tex]

Therefore we can say that [tex]\mathbf{x=\frac{1}{2}}[/tex] is the solution to the equation: [tex]4x+12-8x=-1+2x+10[/tex]

The statement is true.

Option A is correct.

Answer:

Input value/x = 9

Step-by-step explanation:

The output value means y and the input value means x.

So they've told us the output value y = 4.5

Sub this into the function they gave us to get x

y=x/2

4.5=x/2

9=x

The probability that the product of the numbers spun is 12 is [tex]4\div 36[/tex]

Since The spinner shown has six equal-size sections and is spun twice.

So, here there are 6 numbers and if spines twice other 6, if these are multiplied with each other there will be a total of 36 products or probabilities.

And, On total, there are four 12

Step-by-step explanation:

rise over run

Answer:

-1/3

Step-by-step explanation:

1/3 - 2/3 = -1/3

An easier way to do this is keep the denominator the same (3), and then subtract the numerator. 1 - 2 = -1, and the "-1" is the numerator, and the 3 will be the denominator. So....

-1/3

Check

-1/3 + 2/3 = 1/3 CORRECT

Answer:

d

Step-by-step explanation:

the answer is d 17 miles/gallon

Answer: B) 11 miles/gallon

This can be written as 11 miles per gallon and shortened to 11 mpg

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

Explanation:

The odometer reads 143,986 miles when the gas tank is full.

Then it reads 144,261 miles when the gas tank is empty (when all the gas is used up).

This is a difference of 144,261-143,986 = 275 miles.

The truck's gas tank has a capacity of 25 gallons, so this means

(275 miles)/(25 gallons) = 11 miles/gallon = 11 miles per gallon

is the gas mileage of the truck.

----------------

Put another way:

We know the truck traveled 275 miles on 25 gallons. We can form this ratio

275 miles : 25 gallons

Divide both parts by 25 to get the "25 gallons" to turn into "1 gallon"

275 miles : 25 gallons

275/25 miles : 25/25 gallons

11 miles : 1 gallon

Therefore, each gallon of gas will let the truck drive 11 miles. So the truck gets 11 mpg.

Answer:

1. Each class would have 105 pencils with 2 remaining

2. x = 114 persons

3. 912 marbles

4. 27 children

Step-by-step explanation:

1. If Miss Johnson has 737 new pencils and wants to share them out

equally between the 7 classes, how many would each class get?

Are there any left over?

Let the number of pencils = x

7 × x = 737 pencils

x = 737/7

x = 105 2/7 pencils

Therefore, each class would have 735 pencils, with a remainder of 2 pencils

2. A tour driver has £342 at the end of his shift, if all tickets were £3, how

many people have ridden on his tour today?

Let the number of people = x

£3 × x = £342

x = £342/£3

x = 114 persons

3. 24 children all collect marbles. They each have 38 marbles.

How many do they have in total?

The total number of marbles is calculated as:

1 child = 38 marbles

24 children = x

x = 24 × 38 marbles

x = 912 marbles

4. There are 135 children in a school and 5 houses. How many

children are in each house?

5 houses = 135 children

1 house = x children

5x = 135 children

x = 135/5

x = 27 children

Answer:

0.6826

Step-by-step explanation:

The high temperatures for days in January are Normally distributed with a mean of 38 degrees Fahrenheit and a standard deviation of 5 degrees . How many days in January will have temperatures between 33 degrees Fahrenheit and 43 degrees Fahrenheit ? Round your answer to two decimal places.

Solution:

The z score is a score used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by the formula:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ \mu=mean,s=raw\ score \ and\ \sigma=standard\ deviation\\\\Given\ that\ \mu=38^oF,\sigma=5^oF\\\\For\ x=33^oF\\\\z=\frac{x-\mu}{\sigma}=\frac{33-38}{5}= -1\\\\For\ x=43^oF\\\\z=\frac{x-\mu}{\sigma}=\frac{43-38}{5}= 1\\\\[/tex]

From the normal distribution table, P(33 < x < 43) = P(-1 < z < 1) = P(z < 1) - P(z < -1) = 0.8413 - 0.1587 = 0.6826

Step-by-step explanation:

Before we find the amount Mr Stubbert paid, we'll have to find the value of the coupon.

To do this, we will have to multiply the Original Price with the Rate of Discount.

A Rate of Discount is your coupon into decimal form. In this case, it would be [tex]\multiply {0.15}[/tex]

So now we will multiply.

[tex]\text{520 x 0.15 =} \underline {78}[/tex]

So [tex]78[/tex] is going to be our discount.

Now that we've found the discount, let's subtract [tex]78[/tex] from [tex]520[/tex].

[tex]\text{520 - 78 = 442}[/tex]
