Answer:

It's neither

Step-by-step explanation:

The only factor of 1 is 1.

A prime number has exactly two factors so 1 isn't prime.

A composite number has more than 2 factors, so 1 isn't composite either.

so... it's a neutral number.

Hope this helps!

Choose the graph which represents the solution to the inequality. 12x + 4 ≤ -8

user100 [1]

Answer:

Step-by-step explanation:

Steps:

$12x+4-4\leq -8$

Subtract 4 from both sides:

$12x+4-4\leq -8-4$

Simplify:

$12x\leq \frac{-12}{12}$

Divide both sides by 12:

$\frac{12x}{12} \leq \frac{-12}{12}$

Simplify:

$x\leq -1$

A popcorn company builds a machine to fill 1 kg bags of popcorn. They test the first hundred bags filled and find that the bags

ELEN [110]

Answer:

Step-by-step explanation:

Given that a popcorn company builds a machine to fill 1 kg bags of popcorn. They test the first hundred bags filled and find that the bags have an average weight of 1,040 grams with a standard deviation of 25 grams.

i.e. Sample mean = 1040 and

Sample std dev s = 25 gm

Sample size n = 100

Hence by central limit theorem we have the sample mean follows a normal distribution with mean =1040 and std dev = s = 25 gm

$\bar X = N(1040,25)$

Normal curve would be with mean 1040 and std deviatin 25

b) P(X>1115)

= 1-0.9987

=0.0013

i.e. 0.13% would receive a bag that had a weight greater than 1115 grams

A coat cost $ 131.61 with 9.5% sales tax

marysya [2.9K]

Calculating Total Cost. Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost. Multiply retail price by tax rate

Let's say you're buying a $100 item with a sales tax of 5%. Your math would be simply: [cost of the item] x [percentage as a decimal] = [sales tax]. That's $100 x .
