Answer:
Step-by-step explanation:
Let X be a random sample representing the score of a student in the American Chemical Society Examination.
P(450 < x < 500) = P((450 - 500)/(90/sqrt(25)) < z < (500 - 500)/(90/sqrt(25))) = P(-2.778 < z < 0) = P(z < 0) - P(z < -2.778) = P(z < 0) - [1 - P(z < 2.778)] = P(z < 0) + P(z < 2.778) - 1 = 0.5 + 0.99727 - 1 = 0.49727 = 49.7%
Answer:
F,D. C,D
Step-by-step explanation:
This is all I know the F and D make a right angle and the C,D make a 360 degree angle.
Answer:
Thursday
Step-by-step explanation:
We are given the changes in the low temperature compared to the day before.
Now, first we find the difference in temperature occurring on each day.
As, difference = | current value - previous value |.
So, we get the differences as,
Wednesday = | 4.1 - 3.5 | = 0.6
Thursday = | 0 - 4.1 | = 4.1
Friday = | 2.2 - 0 | = 2.2
Now, as we see that the maximum difference i.e 4.1 occurs on Thursday.
Hence, the most change in the temperature occurs on Thursday.
Answer:
No. The ladder is too steep.
Step-by-step explanation:
Length of ladder = 17 feet. This is the hypotenuse.
Side a of a right triangle = 16.6
To answer this, you need one of the trigonometric functions.
Opposite = 16.5
hypotenuse = 17
The function you need is the sine function.
Sin(theta) = opposite / hypotenuse
sin(theta) = 16.5 / 17
Sin(theta) = 0.97059
theta = sin-1(0.07059)
theta = 76.07
No the ladder is too steep.
