Answer:
That would be 175% since in your question or the way you phrased it atleast, 100%=4, so 1 would be 25%, 25% times 3=75 so 175% =4+3=7
Step-by-step explanation:
11/3 divides by 60/11 = 660/33 = 20
Answer:
13, 15, 17
Step-by-step explanation:
Gọi 3 STN lẻ cần tìm là a, a+2, a+4 (a thuộc N*)
Theo đề bài ta có:
(a + 2)(a + 4) - 177 = 6a
=> a^2 + 4a + 2a + 8 = 6a + 177
=> a^2 + 6a + 8 = 6a + 177
=> a^2 + 6a - 6a = 177 - 8 (chuyển vế)
=> a^2 = 169 = 13^2
=> a = 13
=> a+2 = 15, a+4 = 17
Vậy 3 STN lẻ cần tìm là 13, 15, 17
It hard for me too but I think I got it
Answer:
The upper limit for the 95% confidence interval for the population proportion of defective gaming systems is 0.022
Step-by-step explanation:
Upper Limit for 95% Confidence Interval can be calculated using p+ME where
- p is the sample proportion of defective gaming systems (
)
- ME is the margin of error from the mean
and margin of error (ME) around the mean can be found using the formula
ME=
where
- z is the statistic of 95% confidence level (1.96)
- p is the sample proportion (

- N is the sample size (1200)
Using the numbers we get:
ME=
≈ 0.007
Then upper limit for the population proportion is 0.015+0.007 =0.022
