Count the length of each side then divide it by 2, then draw those sides, and you will have the 1/8 in.:4ft scale
The length of the actual room, assuming each square is 1/4 in. long, is 40ft and the width is 24ft
And then the area would be 40 * 24 = 960 sqft.

Kamila [148]

Answer:

Step-by-step explanation:

This is because when two angles of a traiangle are equal, it is obvious that the third angle of the triangles is equal too. Therefore, when all three angles of a triangle are equal, they are similar with the third-angle theorem.

If a CONE has a DIAMETER of 10 centimeters and a Volume of 225 cubic centimeters, what is its approximate HEIGHT

ch4aika [34]

Answer:

The approximate height is 8.9 cm

Step-by-step explanation:

To find the height of a cone with a diameter of 10 cm and a volume of 225 cubic centimeter, we will follow the steps below;

first, write down the formula for finding the volume of a cone

v=πr² $\frac{h}{3}$

where v is the volume of the cone

r is the radius and h is the height of the cone

from the question given,

diameter = 10 cm but d=2r this implies that r= $\frac{d}{2}$ r= 10/2 = 5cm

hence r= 5cm

Also v= 225 cm³

π is a constant and is ≈ 3.14

We can now proceed to insert the values into formula and then solve for h

v=πr² $\frac{h}{3}$

225 ≈ 3.14 × 5² × $\frac{h}{3}$

225 ≈ 78.5 × $\frac{h}{3}$

225 ≈ $\frac{75.8 h}{3}$

cross-multiply

675 = 75.8 h

divide both-side of the equation by 75.8

8.9 ≈ h

h≈ 8.9

Therefore, the approximate height is 8.9 cm

Assume that a procedure yields a geometric distribution where the probability of success is 19%. Use the geometric probability f

Rudiy27

The probability that the first success occurs on the third trial is 0.125.

Answer: Option C

<u>Step-by-step explanation:</u>

The probability of success is given by the geometric distribution formula:

$P(X=x)=p \times q^{x-1}$

Where,

p = probability of success for single trial.

q = probability of failure for a single trial (1-p)

x = the number of failures before a success.

P(X = x) = Probability of x successes in n trials.

<u>Given: </u>

p = 19% = 0.19

q = 1 – p = 1 – 0.19 = 0.81

x = 3

We want to find the probability that the first success occurs on the third trial so,

$P(X=3)=0.19 \times 0.81^{(3-1)}$

$P(X=3)=0.19 \times 0.81^{2}$

$P(X=3)=0.19 \times 0.6561=0.125$

M and n are both integers. Select all the statements that are true if m and n are also equal to each other.

telo118 [61]

The question is incomplete. The complete question is :

M and n are both integers. Select all the statements that are true if m and n are also equal to each other.

A. m - n = n - m

B. 0 = m - n

C. m + (-n) = m - n

D. m + n = 0

Answer :

A. m - n = n - m

B. 0 = m - n

C. m + (-n) = m - n

Explanation :

It is given that m and n are integers and they both are equal to each other.

i.e. m = n

Therefore for option (A),

m - n = n - m

m - m = m - m (since m and n are equal)

0 = 0

Therefore, the statement (A) is true.

For option (B),

0 = m - n

0 = m - m (since m and n are equal)

0 = 0

Therefore, the statement (B) is true.

For option (C),

m + (-n) = m - n

m + (-m) = m - m (since m and n are equal)

m - m = m - m

0 = 0

Therefore, the statement (C) is true.

Now for option (D),

m + n = 0

m + m ≠ 0 (since m and n are equal)

2m ≠ 0

Therefore, the statement (D) is false.

Hence, the options (A), (B) and (C) are true.
