Answer 8.17

Step-by-step explanation:

1.divide 98 by twelve, since there are 12 inches in a foot

98 \ 12

2.then round to the nearest tenth. 8.16 is rounded to 8.17

Tasya [4]

Answer:

The correct option is 1.

Step-by-step explanation:

Two triangles are called similar if all the corresponding angles are congruent or all corresponding sides are in same proportion.

In triangle MNO and triangle RTS.

$\angle M\cong\angle R=54.4^{\circ}$ (Given)

$\angle N\cong\angle T=71.2^{\circ}$ (Given)

According to the angle sum property, the sum of all interior angles of a triangle is 180 degree. Since two corresponding angles are congruent, therefore third angle is also congruent.

$\angle O\cong\angle S=54.4^{\circ}$

Since all corresponding angles are congruent, therefore the triangles MNO and RTS similar.

The triangle are congruent by AA rule of similarity. Each triangle has two congruent angles, therefore both triangles are similar. Option 1 is correct.

stiks02 [169]

Answer:

a. Yes

b. 0.35

c. 0.5

E(x)=34.25

V(x)=73.1875

SD(x)=8.555

Step-by-step explanation:

x 20 25 30 35 40 45 50

f(x) 0.05 0.2 0.25 0.15 0.15 0.1 0.1

This will be valid probability distribution if

1. All probabilities are between 0 and 1 inclusive.

2. Sum of probabilities must be 1.

Condition 1 is satisfied in this distribution. Now, we will check second condition

sum(f(x))=0.05+0.2+0.25+0.15+0.15+0.1+0.1=1.

As the both conditions are satisfied, thus the given distribution is a valid probability distribution.

P(x≥40)=P(X=40)+P(X=45)+P(X=50)

P(x≥40)=0.15+0.1+0.1

P(x≥40)=0.35

So, the probability that Backens and Hayes LLC will obtain 40 or more new clients is 0.35.

P(x<35)=P(X=20)+P(X=25)+P(X=30)

P(x<35)=0.05+0.2+0.25

P(x<35)=0.5

So, the probability that Backens and Hayes LLC will obtain fewer than 35 new clients is 0.5.

Expected value of x=E(x)= sum[x*f(x)]

E(x)= 20*0.05+25*0.2+30*0.25+35*0.15+40*0.15+45*0.1+50*0.1

E(x)=1+5+7.5+5.25+6+4.5+5

E(x)=34.25

Variance of x=V(x)=sum[x²*f(x)]-(sum[x*f(x)])²

sum[x²*f(x)]= 20²*0.05 +25²*0.2 +30²*0.25 +35²*0.15 +40²*0.15 +45²*0.1 +50²*0.1

sum[x²*f(x)]=20+1255+225+183.75+240+202.5+50

sum[x²*f(x)]=1246.25

V(x)=1246.25-(34.25)²

V(x)=73.1875

Standard deviation of x=SD(x)=√V(x)

SD(x)=8.555

Find the approximate volume of this prism.

musickatia [10]

Answer:

62m³

Step-by-step explanation:

The question is incomplete. Find the diagram of the prism attached below.

Volume of a Prism = Base area × Height

Given height = 9m

Since the prism is a triangular based prism,

Base area = area of the equilateral triangle = 1/2bh

base of the triangle = 4m

Height can be gotten using Pythagoras theorem.

Slant side of the triangle is the hypotenuse = 4m

Adjacent = 1/2 of the base = 1/2(4)= 2m

Height = √4²-2²

Height = √16-4

Height of the triangle= √12 m

Base Area = 1/2×4×√12

Base Area = 2√12 m

Volume of the prism = 2√12 × 9

= 2×2√3×9

= 36√3 m³

= 62.2m³

Volume of the prism is approximately 62m³
