(Sin A/ secA) × ( sec A / cos A) = Sin A / cos A = tan A
Question should be cos A ÷ sec A
Answer:
Use desmos.
Step-by-step explanation:
In the image attached, I graphed the linear function on a graphing calculator. B=7 and the slope is 3.
There are 12 inches in a foot.
Divide 94 by 12.
94 / 12 = 7.8333
So there are 7 feet and a few inches.
Now we multiply 12 to 7.
12 * 7 = 84
Subtract this from 94.
94 - 84 = 10
So there are 7 feet and 10 inches in 94 inches.
The answer to this question is 23. How you get this is by adding all the sides like this: 2n+6+135+151+140+63=540. Then you just solve the equation.
For this Q:
mean=31
st.dev.=0.8
x=32
Calculate z-score:
z=(x-m)/s = (32-31)/0.8=1.25
This z-score value corresponding to the probability of 0.8944
