7 x 14 = 98, 100 - 98 = 2.

She gives 14 cubes to each group, and there are 2 cubes leftover.

Hope this helps!

Answer:

<em>The approximate percentage of cars that remain in service between 73 and 84 months</em>

<em>P( 73 < x < 84 ) = 0.02145 = 2.1 %</em>

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

<u><em>Explanation</em></u>:-

Given mean of the Population 'μ ' = 51 months

Standard deviation of the Population 'σ' = 11 months

Let 'X' be the random variable of Normal distribution

<em>Let 'X' = 73</em>

<em></em> $Z = \frac{x-mean}{S.D} = \frac{73-51}{11} = 2$ <em></em>

<em>Let 'X' = 84</em>

<em></em> $Z = \frac{84-51}{11} = 3$ <em></em>

<em>The approximate percentage of cars that remain in service between 73 and 84 months</em>

<em>P( 73 < x < 84 ) = P( 2 < Z < 3)</em>

<em> = P( Z<3) - P( Z <2)</em>

<em> = 0.5 + A(3) - ( 0.5 + A(2))</em>

<em> = A(3) - A( 2)</em>

<em> = 0.49865 - 0.4772 ( From Normal table)</em>

<em> = 0.02145</em>

<em> P( 73 < x < 84 ) = 0.02145</em>

<em>The approximate percentage of cars that remain in service between 73 and 84 months</em>

<em>P( 73 < x < 84 ) = 0.02145 = 2.1 %</em>

AB is a diameter of a circle, center O. C is a point on the circumference of the circle, such that

Solnce55 [7]

Given:

AB is the diameter of a circle.

m∠CAB = 26°

To find:

The measure of m∠CBA.

Solution:

Angle formed in the diameter of a circle is always 90°.

⇒ m∠ACB = 90°

In triangle ACB,

Sum of the angles in the triangle = 180°

m∠CAB + m∠ACB + m∠CBA = 180°

26° + 90° + m∠CBA = 180°

116° + m∠CBA = 180°

Subtract 116° from both sides.

116° + m∠CBA - 116° = 180° - 116°

m∠CBA = 64°

The measure of m∠CBA is 64°.
