Answer: 0.4255

Step-by-step explanation:

Given:  IQ scores of adults, and those scores are normally distributed

Mean: \mu=100

Standard deviation: \sigma= 15

Let X denotes the IQ of a random adults.

The area between 102 and 130 = P(102

=P(0.13

Hence, area between 102 and 130 = 0.4255

Thr four angles of a quadrilateral L are in the ratio 5:2:3:8find the angle
Anuta_ua [19.1K]
Ratio = 5:2:3:8
Sum of all internal angles = 360°
5x + 2x + 3x + 8x = 360°
18x = 360°
x = 20°
Therefore,
5x = 100°
2x = 40°
3x = 60°
8x = 160°
5:2:3:8 :: 100:40:60:160.

Let angle G be an acute angle and tan G = 0.43 . Use technology to approximate the measure of angle G to the nearest 10th of a d
klasskru [66]

We need to use the calculator, using the tan⁻¹ function:

\begin{gathered} \tan(G)=0.43 \\ \tan^{-1}(\tan(G))=\tan^{-1}(0.43) \\ G=\tan^{-1}(0.43) \end{gathered}

Using the calculator:

G=\tan^{-1}(0.43)=23.26770481

To the nearest tenth:

G=23.3º

Rachel rode her bike for seven -quarters of a mile on Monday and nine-fifths of a mile on Tuesday. How many miles did she ride a
Romashka [77]

Answer:

3 11/20 miles

Step-by-step explanation:

Monday = seven -quarters of a mile

= 7/4 miles

Tuesday = nine-fifths of a mile

= 9/5 miles

How many miles did she ride altogether?

Total miles she rode altogether = Monday + Tuesday

= 7/4 + 9/5

= (35+36)/20

= 71/20

= 3 11/20

Total miles she rode altogether = 3 11/20 miles

a mechanical engineer designs a robotic rm to be used in an assembly line. one portion of the arm is 5/12 yard long, and the len
Amanda [17]

Answer:

  8/12 yard or 2/3 yard

Step-by-step explanation:

The sum of the two lengths is ...

  5/12 yd + 3/12 yd = (5+3)/12 yd = 8/12 yd

This fraction can be reduced by removing a factor of 4 from numerator and denominator.

  8/12 yd = 2/3 yd

If the arm portions are end-to-end, the total length is 2/3 yard.
