What is the weekly gross pay?
romanna [79]
You want to multiply 40 hours by the regular hourly pay which would be $9.14,
9.14*40= 365.6

Overtime is generally 1.5 times regular pay so take 9.14*1.5= 13.71 and this would be your overtime hourly rate

Regular hourly rate (1x) : $9.14
Overtime hourly rate (1.5x): $13.71

Take your 8 hours of OT and multiply it by 13.71
13.71*8= 109.68

Add 365.6 and 109.68 to get a final answer of 475.28. The answer would've been C

The heights of women aged 30 to 35 are approximately Normal with mean 63 inches and standard deviation 2.4 inches. Men the same
gavmur [86]

Answer

given,

mean of women  (μ)=63 inches

standard deviation of women (σ)= 2.4 inches

mean of men (μ)=70 inches

standard deviation of women (σ)= 2.5 inches

for women

P(x>66)

P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}

P(x>66) = 1-P( z

P(x>66) = 1-P( z

using z-table

P(x>66)= 1 - 0.8944

P(x>66)=0.1056[/tex]for men[tex]P(x>66)

P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}

P(x>66) = 1-P( z

P(x>66) = 1-P( z

using z-table

P(x>66)= 1 - 0.0548

P(x>66)=0.9452

What is the exact value? (Picture provided)
creativ13 [48]

Answer:

b.  (√15)/4

Step-by-step explanation:

Since Sin Ф = (opposite side)/Hypotenuse, we have 2 sides of a right triangle.  

Use Pythagorean theorem to solve for the missing leg (the adjacent side)

 1² + b² = 4²

    1 + b² = 16

            b² = 15

                 b = √15

So the adjacent side is √15, so Cos Ф = (√15)/4

Find AE in the parallelogram, if BD = 12, and AC = 18
Liono4ka [1.6K]
See the picture in the attached figure

we know that

There are six important properties of parallelograms to know:

<span>1) Opposite sides are congruent (AB = DC).
2) Opposite angels are congruent (D = B).
3) Consecutive angles are supplementary (A + D = 180°).
4) If one angle is right, then all angles are right.
5) The diagonals of a parallelogram bisect each other.
<span>6) Each diagonal of a parallelogram separates it into two congruent triangles.

so
if t</span></span>he diagonals of a parallelogram bisect each other
then 
AE=EC
AC=AE+EC------> AC=2*AE----> AE=AC/2----> AE=18/2----> AE=9 units

the answer is
AE=9 units
