Since a is parallel to c and c is perpendicular to b, than a is also perpendicular to b.

perpendicular lines create right angles, so angle 1, 2, 3, 4, 5, 6 .7 & 8 are all right angles.
A right angle = 90 degrees.

Angle 2 = 90 degrees.

The weights of 1,000 men in a certain town follow a normal distribution with a mean of 150 pounds and a standard deviation of 15

uysha [10]

Z = ( 135 - μ ) / σ = -1
z = ( 165 - μ ) / σ = 1
P (x < 135) = P (z < -1) = 0.1587
P (165 < x) = P (1 < z) = 0.1587
.187 * 1000 = 187 more than 165
<span>.187 * 1000 = 187 less than 135</span>

What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?

The value of n in given proportion is 16

<u><em>Solution:</em></u>

We have to find the value of "n" in the proportion

<em><u>Given proportion is:</u></em>

<em><u></u></em> $\frac{n}{28} = \frac{4}{7}$ <em><u></u></em>

We can solve the above proportion by cross-multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable

$->\frac{n}{28} = \frac{4}{7}$

$-> 7 * n = 4 * 28$

$-> n = \frac{4 * 28}{7}$

$-> n = 4 * 4 = 16$

Thus the value of n in given proportion is 16
