Answer:
<h2><em><u>7d + 4f - 15</u></em></h2>
Explanation:
-3 + 4d - 2f + 3d + 6f - 4 - 8
= −3 + 4d + −2f + 3d + 6f + −4 + −8
= −3 + 4d + −2f + 3d + 6f + −4 + −8
(4d + 3d) + (−2f + 6f) + (−3 + −4 + −8)
7d + 4f + −15
= 7d + 4f - 15
Answer:
34% of lightbulb replacement requests numbering between 47 and 52
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 52
Standard deviation = 5
Between 47 and 52:
52 is the mean and 47 is one standard deviation below the mean.
By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean.
Since the normal distribution is symmetric, of those, 34% are within 1 standard deviation below the mean and the mean(47 and 52) and 34% are within the mean and one standard deviation above the mean(52 and 57).
So
34% of lightbulb replacement requests numbering between 47 and 52
Answer:
acute angle measure less than 90 degrees, right angle measure 90 degrees, Obtuse angle measure more than 90 degrees, straight angle equal to 180 degrees, reflex angle is an angle greater than 180° and less than 360°, complementary angle either of two angles whose sum is 90°, supplementary angle either of two angles whose sum is 180°
Step-by-step explanation:
f(x) = + 8
x = 10?
f(10)= +8
no change
Answer:
B is equal to 10
Step-by-step explanation:
You can add those two numbers together and set equal to 90. This would allow you to solve for B
B + 3B + 50 = 90
4B + 50 = 90
4B = 40
B = 10
