Answer:
<h2>c = √130</h2>
Step-by-step explanation:
To solve for c we use the formula for Pythagoras theorem
That's
a² = b² + c²
Where a is the hypotenuse
From the question above
c is the hypotenuse
So we have
c² = 9² + 7²
c ² = 81 + 49
c² = 130
Find the square root of both sides
<h3>c = √130</h3>

Answer:
15 inches
Step-by-step explanation:
12 inches = 1ft
12ft = 144 inches
144/9 = 16

240/16 = 15 inches
Answer:
Step-by-step explanation:
The null and alternative hypothesis that would seek to challenge this belief would be
Null hypothesis: u = 0.75
Alternative hypothesis: u =/ 0.75
The type of test to be used would be a one sample z test where one sample is drawn from the population and the mean engagement of students who become knowledgeable in the material is measured and tested in an experiment against the null hypothesis.
Answer:
x = 32
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x
/2 −7=9
1
/2
x + (−7) = 9
1
/2
x − 7 = 9
Step 2: Add 7 to both sides.
1
/2x − 7 + 7 = 9 + 7

/2
x = 16
Step 3: Multiply both sides by 2.
2*(

/2
x) = (2) * (16)
x = 32
