Answer:

y = 1/2x - 2

Step-by-step explanation:

Slope intercept form:

y = mx + b

x - 2y = 4

-2y = -x + 4

2y = x - 4

y = 1/2x - 2

Answer: It is not.

Step-by-step explanation:

The salaries paid to the various departments of a company are usually different as some departments get paid more than others. For instance, in a manufacturing company, the R&D department would on average, get paid more than members of the Cleaning department.

Asking members of only one department therefore, about their pay satisfaction would not bring about a reasonable result because it would not be indicative of the thoughts of members of the other departments who are not being paid the same.

Step-by-step explanation:

Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean  and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean.

here, we have,

Given,

In the question:

The times to pop a regular bag of microwave popcorn without burning it are Normally distributed with a mean time of 140 seconds and a standard deviation of 20 seconds. The times to pop a mini bag of microwave popcorn without burning it are Normally distributed with a mean time of 90 seconds and a standard deviation of 15 seconds.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of 140, standard deviation of 20, sample of 4:

By the Central Limit Theorem, the distribution is approximately normal.

Mean is the same, of 140.

n = 4 , σ = 20, thus:

s = σ /√n  

 = 20/√4

 = 10

Thus, the correct answer is:

Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.

Answer:

x=12

Step-by-step explanation:

4x+16=64

to isolate x, take 16 from both sides

4x+ 16(-16)=64-16

4x=48

divide 4 on each side

4x/4=x

48/4=12

x=12

The solution of the equation 4x+16= 64 is x = 12.

The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.

For this case, we've to solve for x, the equation [tex]4x + 16 = 64[/tex]

Subtracting 16 from both the sides:

[tex]4x + 16 - 16 = 64 - 16\\4x + 0 = 48\\4x = 48[/tex]

4x is actually 4 times x, and is written in short, where the multiplication sign is hidden. This is usually done when variables like x,y are there.

Dividing both the sides by 4, we can get x on one side, and rest of the constant values on the other side.

[tex]\dfrac{4x}{4} = \dfrac{48}{4}\\\\1 \times x = 12\\x = 12[/tex]

(since 1 times any number is that number itself, and as x represents a number, so we got 1 times x =x).

Thus, the solution of the equation 4x+16= 64 is x = 12.

Distance cover by Brent in 2 Lap = 104 meter

Step-by-step explanation:

Given:

Length of football field = 14 m

Width of football field = 12 m

Find:

Distance cover by Brent in 2 Lap

Computation:

Distance cover by Brent in 2 Lap = 2 x Perimeter of rectangular field

Perimeter of rectangle = 2[l+b]

Perimeter of rectangular field = 2[14 + 12]

Perimeter of rectangular field = 2[26]

Perimeter of rectangular field = 52 m

Distance cover by Brent in 2 Lap = 2 x Perimeter of rectangular field

Distance cover by Brent in 2 Lap = 2 x 52

Distance cover by Brent in 2 Lap = 104 meter

Answer: Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50

Step-by-step explanation:

Since Sara asked 100 of the students for their favorite lunch but there are 500 students in a school, this means that the items listed will have to be multiplied by 5 (500/100) in order to get the number of students in the whole school that'll need the items listed. This will therefore be:

Pizza = 45 × 5 = 225

Burritos = 15 × 5 = 75

Hamburgers = 30 × 5 = 150

Hot dogs = 10 × 5 = 50

The correct option is A:

Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50

Answer:

Step-by-step explanation:

its d cause there is actually 208 nickles and if u ad 8 more it gives u 216.

Answer: D.

Step-by-step explanation:

52x4=208

Since we know she has 4 times as many nickels as dimes(52), we just have to multiply 52x4 to get 208 nickels

208+8=216

We know that she has 8 more quarters than nickels(208) so we have to add 8 to 208 to get 216 quarters

Answer:

1&(1/2) or 1.5 or 3/2 cups flour needed for 36 cookies

Step-by-step explanation:

Flour : Cookie ratio (Flour needed to make particular cookie) = 1 : 24

1 cup flour make 24 cookies, so 1/2 cup floor make 12 (half) cookies.

So, 1&(1/2) or 1.5 or 3/2 cups would make 24 + 12, ie = 36 cookies

Multiplying numerator & denominator of fractional ratio 1 : 24 with 1.5 each

(1 x 1.5) : (24 x 1.5)

It implies 1.5 : 36 flour cookie ratio
