Hello!
Experimental probability is the probability in relation to the data that has been collected. In this example, adding up the times spun we get 18 times spun. Where red was spun 6 times, this is 1/3 of what was done.
Our answer is B) 1/3.
Hope this helped!
Answer:
Answer is below
Step-by-step explanation:
x - 3 < 22
If you need to solve for x the equation would be x < 25
Answer:
x = 128 degrees
Step-by-step explanation:
First figure out the angle inside the triangle
1st step: add 55 and 73 together:
⇒ 55 + 73 = 128
2nd step: subtract the sum from 180:
⇒ 180 - 128 = 52
to find x, take 180 again and then subtract 52 from it:
⇒ 180 - 52 = 128
Answer:
(0.0706, 0.1294)
Step-by-step explanation:
Confidence interval of a proportion is:
CI = p ± CV × SE
where p is the proportion,
CV is the critical value (z score or t score),
and SE is the standard error.
The sample is large enough to estimate as normal. For 95% confidence level, CV = z = 1.96.
Standard error for a proportion is:
SE = √(pq/n)
SE = √(0.1 × 0.9 / 400)
SE = 0.015
The confidence interval is:
CI = 0.1 ± (1.96)(0.015)
CI = (0.0706, 0.1294)
Round as needed.
First choice in the upper left corner.
It is the same shape with same proportions, just dilated.
2/5 = 0.4
8/20 = 0.4
