2 answers:

A percent is a decimal multiplied by 100. 0.5, for example, is 50% because 0.5 x 100 is 50. So 20% is 0.2. Multiply 350 by 0.2 to get 20 percent of 350

350 x 0.2= 70
$70 is 20% of 350

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.

PLEASE SOMEBODY ANSWER

Kipish [7]

Answer:

Step-by-step explanation:

2ab cos C=a²+b²-c²

2×31×14 cos C=31²+14²-40²

868 cos C=961+196-1600=-443

cos C=-443/868

C=cos^{-1}(-443/868)≈120.688≈120.69°

by sine formula

m∠B=180-(62+55)=180-117=63°

$\frac{AC}{sin~B} =\frac{AB}{sin~C} \\\frac{240}{sin 63} =\frac{AB}{sin~55} \\AB=\frac{sin~55}{sin~63} \times 240 \approx 220.645 \approx 220.65 ~ft$
