The probability that the result is a multiple of
2 and a multiple of 5 is; 0.1
We are told that:
-The spinner has 10 equal areas
- Numbers on the spinner are 1 to 10
Thus,
Total available numbers; N = 10 numbers
We want to find the probability that the result
is a multiple of both 2 and 5.
Now,among all the digits from 1 to 10, the
only one that is a multiple of both 2 and 5 is
10.
Thus,
P(result is a multiple of 2 and a multiple of 5)
= 1/10 = 0.1
Answer:
76.
Step-by-step explanation:
Here, a=3, b=-10 and c=2. Substitute the values, Therefore, the discriminant of is 76.
Answer: 8=x+5, x-3=5
Step-by-step explanation: Find the value of ‘x’ by subtracting 5 in the first equation. Add 3 to the second equation.
The mean price goes between $ 41.16 and $ 42.84, so a value of $ 48 is unusually high.
Since the average price of an item is $ 42 with a standard deviation of $ 3, to find a 98% confidence interval about the mean, and determine if a value of X = 48 is unusually high or if it is normal, the following calculations should be done:
- (((42 - 3) + (42 + 3)) / 2) x 0.98 = X
- ((39 + 45) / 2) x 0.98 = X
- 42 x 0.98 = X
- 41.16 = X
- (((42 - 3) + (42 + 3)) / 2) x 1.02 = X
- ((39 + 45) / 2) x 1.02 = X
- 42 x 1.02 = X
- 42.84 = X
Therefore, as the mean price goes between $ 41.16 and $ 42.84, a value of $ 48 is unusually high.

Answer: Option D is correct.
Step-by-step explanation:
Since we have given that
focus = (-5,5)
and a directrix y= -1
Since, equation of parabola in this case will be
Now, here
So equation will be
So, option D is correct .
