Answer:
100 points
Step-by-step explanation:
-75 + 200 = 125
125 - 25 = 100
So, the problem is 2x - 3x - 2 • 1/7x ?
2x - 3x - 2 • 1/7x
So, combine like terms.
-1x - 2 • 1/7x
-1/7x • 2
The answer would be about -0.3x ?
If I’m understanding correctly.
Answer:
A) 34.13%
B) 15.87%
C) 95.44%
D) 97.72%
E) 49.87%
F) 0.13%
Step-by-step explanation:
To find the percent of scores that are between 90 and 100, we need to standardize 90 and 100 using the following equation:
Where m is the mean and s is the standard deviation. Then, 90 and 100 are equal to:
So, the percent of scores that are between 90 and 100 can be calculated using the normal standard table as:
P( 90 < x < 100) = P(-1 < z < 0) = P(z < 0) - P(z < -1)
= 0.5 - 0.1587 = 0.3413
It means that the PERCENT of scores that are between 90 and 100 is 34.13%
At the same way, we can calculated the percentages of B, C, D, E and F as:
B) Over 110
C) Between 80 and 120
D) less than 80
E) Between 70 and 100
F) More than 130
The pro<span>bability of randomly pulling out a pineapple candy would be 5 over 8. Because there are 8 candies total (this is the denominator) and only 3 flavors, you just simply add the two given candies, which is 2 + 1 = 3, and subtract the sum (which is 3) by 8. Therefore, 8 - 3 = 5 and you put that as the numerator and the total number of candies, 8, as the denominator. </span>

Step-by-step explanation:
x cos θ + y sin θ = x cos β + y sin β
<em>Let's say x = cos A, and y = sin A.</em>
cos A cos θ + sin A sin θ = cos A cos β + sin A sin β
<em>Use angle sum formula.</em>
cos(A − θ) = cos(A − β)
A − θ = ±(A − β)
A − θ = β − A
2A = θ + β
A = (θ + β) / 2
cot A = cot((θ + β) / 2)
x/y = cot((θ + β) / 2)
