Answer:
3
Step-by-step explanation:
because 3 times 5 is 15 - 12 is 3
Answer:
<u>16.75 cu. in.</u>
Step-by-step explanation:
Volume = 1/3πr²h
= 1/3 x 3.14 x 4 x 4
= 50.24 / 3
= <u>16.75 cu. in.</u>
There are 100 cm in 1 meter. the dimensions are 400cm by 250cm. depending on which way you turn them, they will fit better. if you take 400 divided by 16, you will have a row of 25 wide and if you divide 250 by 10, you will have a length of 25. you now have 25 rows of 25. 25x25 is 625 tiles.
Answer:
The margin of error for this confidence interval is of 7.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
The margin of error is the subtraction between these bounds, divided by 2.
In this question:
The bounds are 32 and 46.
(46 - 32)/2 = 14/2 = 7
The margin of error for this confidence interval is of 7.
Answer:
The value of x is 5 units ⇒ C
Step-by-step explanation:
In the given figure
∵ Δ ABC is a right triangle at vertex B
∵ AC is its hypotenuse
∵ BD ⊥ AC
∴ (BD)² = AD × DC
∵ BD = 10 units
∵ AD = x units
∵ DC = 4x units
→ Substitute them in the rule above
∴ (10)² = x × 4x
∴ 100 = 4x²
→ Divide both sides by 4
∵ 
= 
∴ 25 = x²
→ Take √ for both sides
∴ 5 = x
∴ The value of x is 5 units
