340/25 = 13.6 = 13 hours and 10 min

30 x 13.6 = 408 hours

25x+30y= 340 and y=2x can be used to determine the number of hours cooper worked and the number of hours isaiah worked. Where x Isaiah 's working hours and y is cooper's working hours.

Step-by-step explanation:

Isaiah ironing rate per hour = 25 shirts

Cooper ironing rate per hour = 30 shirts

Total shirts pressed = 340

Let,

Isaiah´s number of hours = x

Cooper's number of hours = y

According to given statement;

25x+30y=340   Eqn 1

Anne is painting her house light blue. To make the color she wants, she must add 3 cans of white paint to every 2 cans of blue p
GuDViN [60]

Answer:

9 cans of white paint

Step-by-step explanation:

To solve this you can set up a ratio.

The ratio right now is 3 : 2, you have 3 cans of white paint for every 2 cans of blue paint. This question is asking how many white paint cans would be needed for 6 cans of blue paint. You can see the relationship between the number of blue paint cans and the new number of blue paint cans, maybe it's multiplying by 4 or 2 for example, and once we find that out we can do the same exact thing to the white cans.

\frac{3}{2}  = \frac{?}{6}

We can see that to get from 2 to 6 you multiply by 3, so now we do that to the other side of the fraction as well, we multiply by 3. 3 multiplied by 3 is 9, so if we were to have 6 cans of blue paint we would need 9 cans of white paint to get that perfect shade of light blue. Anne would need 9 cans of white paint if she had 6 cans of blue paint to make her shade of blue.

Which of the following describes the probability distribution below?
7nadin3 [17]

Answer:

Answer: A.) The mean is greater than the median, and the majority of the data points are to the left of the mean.

It is clear that most of the data (around 75%) is consist of value 1, which is the leftmost part of the data. Since it was more than 50% of the data, the median should be 1.

if 75% data is 1, it need 25% data with value at least 5 to make the means equal to 2. The means would be bigger than 1 but less than 2, so most(75% data is 1) of the data would be on the left of the mean.
