Answer:
f = 19.0
Step-by-step explanation:
By applying sine rule in the triangle given in the figure,
By applying triangle sum theorem,
m∠F + m∠G + m∠H = 180°
110° + m∠G + 40° = 180°
m∠G + 150° = 180°
m∠G = 30°
[tex]\frac{sin(\angle F)}{GH}= \frac{sin(\angle G)}{HF}=\frac{sin(\angle H)}{FG}[/tex]
[tex]\frac{sin(\angle 110^0)}{f}= \frac{sin(\angle 30^0)}{g}=\frac{sin(\angle 40^0)}{13}[/tex]
[tex]\frac{sin(\angle 110^0)}{f}= \frac{sin(\angle 40^0)}{13}[/tex]
[tex]\frac{0.9397}{f}= \frac{0.6428}{13}[/tex]
f = [tex]\frac{13\times 0.9397}{0.6428}[/tex]
f = 19.0

Answers
Answer: 70, 130
Step-by-step explanation:
In the given normal distribution with a mean of 100 and standard distribution of 15, 95% of values will fall between 70 and 130 using the Empirical rule of 95%.
Step-by-step explanation:
A normal distribution with a mean of 100 and a standard distribution of 15 is given.
We will find where 95% of data fall in the given normal distribution.
What is the Empirical rule of 95%?It states that in a normal distribution approximately 95% of observations fall within two standard deviations from the mean on both sides of the normal curve.
The mean in a normal distribution is the center of the normal curve.
The standard deviation in a normal distribution is the distance from the mean to the required point on either side.
We have,
Mean = 100
Standard deviation = 15
Applying the 95% rule we get,
On the right side of the normal curve
Mean + 2 x standard deviation = 100 + 2x 15 = 100 + 30 = 130.
On the left side of the normal curve,
Mean - 2 x standard deviation = 100 - 2x15 = 100 - 30 = 70.
Thus, we see that by using the Empirical rule of 95%, 95% values will fall between 70 and 130.

C. 3/5
D. 1/8
Answers
Answer:
A, B, D
Step-by-step explanation:
Answer:
A, B, D
Step-by-step explanation:
40% is the same as the fraction 4/10.
Compare 4/10 with 3/20 (A):
LCM of 10 and 20 is 20, so make the denominators of all fractions to 20
We now have 8/20 and 3/20
Now you can just simply look at the numerators. 3 is obviously less than 8 so option A is less than 40%
Compare 4/10 with 23/100 (A):
LCM of 10 and 100 is 100, so make all denominators 100
Now compare 40/100 and 23/100
40>23 so 23/100 is less than 40%
Compare 4/10 with 3/5 (C):
We can further reduce 4/10 to 2/5, and conveniently it has the same denoninator as 3/5. 3 is NOT less than 2, so C is ruled out.
Compare 4/10 with 1/8 (D):
LCM of 10 and 8 is 40, so we'll use that as our denominator
We now have 16/40 and 5/40.
5 is less than 16, so we include D in our answer.

What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:

Newton’s law of cooling states that the temperature of an object changes at a rate proportional to the difference between its temperature and that of its surroundings. Suppose that the temperature of a cup of coffee obeys Newton’s law of cooling. If the coffee has a temperature of 200◦F when freshly poured, and 1 min later has cooled to 190◦F in a room at 70◦F, determine when the coffee reaches a temperature of 150◦F.
Answers
Answer:
6 mins
Step-by-step explanation:
Given that;
T(t) = Ce^-kt + T(s)
Since T(t) = 200◦F, and T(s) = 70◦F where t = 0
200= Ce^-k(0) + 70
C= 200 - 70
C = 130
Then when T(t) = 190◦F and t= 1s ;
190 = 130e^-(k *1) + 70
190 - 70 = 130e-^(k *1)
120/130 = e^k
0.923 = e^-k
-k = ln(0.923)
k = 0.08
To determine the time taken to reach a temperature of 150◦F
150 = 130e^-(0.08t) + 70
150 - 70/130 = e^-(0.08t)
0.6154 = e^-(0.08t)
-(0.08t) = ln 0.6154
0.08t = 0.4855
t = 0.4855/0.08
t = 6 mins
