Answer:

15 days

Step-by-step explanation:

Since he used both of the weights today, he will only do both on the day they come together.

weights: 3 days, 6 days, 9 days, 12 days, 15 days

machine: 5 days, 10 days, 15 days

Because the numbers both were the same on 15 days, then that is when he will do both of them

Cows and horses cost $250 each and sheep and goats each cost $200 at the county fair. Chickens sell for $50. How much could McDo
IgorC [24]

Answer:

the total amount of animals in McDonald's farm is missing, so I looked for a similar question and found the attached image:

McDonald can earn:

15 cows x $250 = $3,750

2 horses x $250 = $500

20 sheep x $200 = $4,000

25 goats x $200 = $5,000

17 chickens x $50 = $850

total = $14,100

marshall27 [118]

Answer:

No Problem, I know That I personally can't stand it when people just give me the number. So another way to think of this problem is "How many 2/3 are in 3 cups." So try drawing 3 rectangles to represent 3 cups and then draw two lines inside those rectangles so that there are 3 rectangles inside each one and then shade in two of the smaller rectangles in a way that you can tell them all apart preferably different colors and then just count them.

Step-by-step explanation:

Hope this is enough to help you understand it, if not then feel free to ask for more info in the comments. :)

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.9 years with a
Bas_tet [7]

Answer:

5.9 years.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

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

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

In this question:

Mean of the population is \mu = 5.9

If a sampling distribution is created using samples of the ages at which 69 children begin reading, what would be the mean of the sampling distribution of sample means?

By the Central Limit Theorem, the same population mean, of 5.9 years.

A line has a zero slope and passes through the point (-5,4). What is the equation of the line?
zhenek [66]

Answer:

y=4

Step-by-step explanation:The answer is y=4 because the line has no slope so it will not increase or decrease at a constant rate. If we were to plug it in it would be y=0/0+4. this basically means that the y-axis is equivalent to 0/0 (no slope) plus 4, we can then cancel out 0 since it is nothing simplifying the equation to y=4.
