Answer:
a=10 students because there are 10 answers.
b=5
Step-by-step explanation:
a=10 students because there are 10 answers.
b, you need to list the numbers all out and rearrange them from smallest to largest.
0, 0, 1, 2, 3, 7, 9, 10, 13, 15
The median means the middle which is 3 and 7
Because we have two numbers, we need to find the middle number of 3 and 7 which is <u><em>5</em></u>
B would be the correct answer
Answer:
48
Step-by-step explanation:
60% of 80 is 48
Answer:
See below for an explanation
Step-by-step explanation:
I'm unsure of your answer choices, so I'll show you how to solve for the remainder of the whole triangle:
Since we are given a hypotenuse of 5 and a side length of 4 which is adjacent to ∅, the trig function to solve for ∅ would be cosine because cos∅=adjacent/hypotenuse (SOHCAHTOA). This means cos∅=4/5 and taking the arccos (the inverse of cosine aka. cos^-1) of both sides gets us ∅=36.87°
Side AC can be solved by using the Pythagorean Theorem since a²+b²=c² can be turned into 4²+b²=5². We would then have 16+b²=25 which is also b²=9, thus taking the square root of both sides gives us b=3 (since distance is positive). Thus, side AC has a length of 3 units.
∠A can be found by using the Triangle Angle-Sum Theorem. Since all the interior angles of a triangle must add up to 180°, then ∠A+∠B+∠C=180°. We know that since ∠B=36.87° and ∠C=90°, then we have the equation ∠A+36.87°+90°=180°. Combining like terms on the left side gets us ∠A+126.87°=180° and subtracting on both sides get us ∠A=53.13°
<u>Final sides and angles of the triangle:</u>
∠A=53.13°
∠B=36.87°
∠C=90°
BC=4
BA=5
AC=3
According to rules of logs, ln(x+1) - ln 3 = ln [(x+1)/3].
x+1
Then your equation becomes ln [ ------------- ] = 8
3
Write the new exponential equation e = e.
Raise the "e" on the left to the power ln [(x+1)/3]. Raise the "e" on the right to the power 8. We get:
x+1
--------- = e^8
3
Then x+1 = 3e^8, and x = 3e^8 - 1 (answer)
