Answer:
The ratio is 1:2, since there are half as many red markers as there are blue.

Answer:
6 mm
Step-by-step explanation:
So, the area he needs to fill isn't really important, you don't need to calculate it. What is necessary is the individual dimensions of that area (width/length). The width and the length must be divisible by the lengths of the tiles. This is so you don't need to cut anything. For example let's say the area needed to be filled was 15 mm (width) by 10 mm (length). If I chose 3mm square tiles, it could perfectly fill up the width, but when it came to the length there would be a small 1 mm gap. And you would need to cut one of the square tiles, so it would have a length of 1 mm. In this case the 15mm was divisible by 3, but the 10 mm wasn't. So using this logic, it can't be the 4 mm square tile since 150mm / 4 mm = 37.5. It can be the 6m since 150mm / 6mm = 25 and 180 mm / 6mm = 30. It can't be the 8 mm since 150 mm / 8mm = 18.75 mm
Green Grapes:
1 pound = $1.85
3 3/5 pounds = $1.85 x 3 3/5
3 3/5 pounds = $6.66
Red Grapes:
1 pound = $2.30
3 3/5 pounds = $2.30 x 3 3/5
3 3/5 pounds = $8.28
Total = $6.66 + $8.28 = $14.94
Answer:
The margin of error is 30.22
Step-by-step explanation:
Sample size 19(lesser than 30), and we only have the sample standard deviation. So we use the t-distribution.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 19 - 1 = 18
Now, we have to find a value of T, which is found looking at the t table, with 18 degrees of freedom(y-axis) and a confidence level of 0.995(
). So we have T = 2.878
The margin of error is:
M = T*s = 10.5*2.878 = 30.22
Answer:
d
Step-by-step explanation:
because a - b is minus 1. and a - b is plus 2. rise over run equals -1 / 2. ur welcome
