If you want to place a 9 3/4 inch towel bar in the center of a door that is 27 and a half wide how much space will be on each si

slava [35]

The answer is inches

Step 1. Subtract length of the door from the width of the door:

Step 2. You want the same space to be on each side of the bar. So, divide the difference from step 1 by 2:

The weights of certain machine components are normally distributed with a mean of 8.04 g and a standard deviation of 0.08 g. Fin

NISA [10]

Answer:

The bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.

Step-by-step explanation:

We are given that

Mean, $\mu=8.04 g$

Standard deviation, $\sigma=0.08g$

We have to find the two weights that separate the top 3% and the bottom 3%.

Let x be the weight of machine components

$P(Xx_2)=0.03$

$P(X$

=0.03

From z- table we get

$P(Z1.88)=0.03$

Therefore, we get

$\frac{x_1-8.04}{0.08}=-1.88$

$x_1-8.04=-1.88\times 0.08$

$x_1=-1.88\times 0.08+8.04$

$x_1=7.8896$

$\frac{x_2-8.04}{0.08}=1.88$

$x_2=1.88\times 0.08+8.04$

$x_2=8.1904$

Hence, the bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.

The vertex angle of an isosceles triangle measures 26° . The base is 30 units long. What is the length of a leg of the isosceles

sergejj [24]

Answer:

65.46 units

Step-by-step explanation:

Given the information:

The vertex angle of an isosceles triangle measures 26°

=> the leg angle is:

= (180° - 26° )/2

= 77°

The base is 30 units

Let x is the length of the leg side (x>0)

We use cosine law to find x, we have:

$30^{2}$ = $x^{2} +x^{2} -2xxCos(26)$ Because the isosceles has two equal leg sides

<=> $30^{2}$ = 2 $x^{2}$ - 1.79 $x^{2}$

<=> 0.21 $x^{2}$ = $30^{2}$

<=> $x^{2} =4285$

<=> x = 65.46 units

Hope it will find you well.
