6 0

Answer:

Step-by-step explanation:

First we find the z-score.

z = (x - μ) / σ

z = (520 - 500) / 60

z = 0.33

Using a calculator or z-score table:

P(z < 0.33) = 0.6293

The probability is approximately 63%. Answer C

In the isosceles trapezoid, m∠S=68∘ .<br><br> What is m∠Q ?

zmey [24]

Answer:

112°

Step-by-step explanation:

Same-side angles of a trapezoid are supplementary.

m∠P = 180° - m∠S = 180° -68° = 112°

The angles of an isosceles trapezoid match their symmetrical counterparts.

m∠Q = m∠P

m∠Q = 112°

Question 6 of 15

umka2103 [35]

Answer:

$LE=5\ units$

Step-by-step explanation:

we know that

In a rectangle, the two diagonals are congruent and each diagonal bisects the other

$LN=2KE$ ----> equation A

$KE=LE$ -----> equation B

step 1

Find the value of x

solve equation A

$LN=2KE$

substitute the given values

$(2x+2)=2(3x-7)$

solve for x

$2x+2=6x-14\\6x-2x=2+14\\4x=16\\x=4$

step 2

Find the value of KE

$KE=3x-7$

substitute the value of x

$KE=3(4)-7=5\ units$

Remember that

$KE=LE$ -----> by each diagonal bisects the other

therefore

$LE=5\ units$
