Answer:

\text{tan}(x)=\frac{4}{3}

Step-by-step explanation:

Please find the attachment.

We have been given that triangle xyz has sides xy = 3", yz = 4", and xz = 5". The angle y is a right angle and side yz is opposite angle x. We are asked to find the \text{tan}(x).  

We know that tangent represents relation between opposite and adjacent side of right triangle.

We can see that adjacent side of our given triangle is xy, so we will get:

\text{tan}(x)=\frac{yz}{xy}

\text{tan}(x)=\frac{4}{3}

Therefore, tan of angle x is \frac{4}{3}.

The weight of trucks traveling on a particular section of I-475 have a population mean of 15.8 tons and a population standard de
Ray Of Light [21]

Answer: 0.0062

Step-by-step explanation:

Given : The weight of trucks traveling on a particular section of I-475 have a population mean of \mu=15.8 tons and a population standard deviation of \sigma=4.2 tons.

Sample size : n=49

Let x be the random variable that represents the weight of trucks .

z-score : z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For x= 14.3 tons

z=\dfrac{14.3-15.8}{\dfrac{4.2}{\sqrt{49}}}\approx-2.5

Now, the probability a state highway inspector could select a sample of 49 trucks and find the sample mean to be 14.3 tons or less will be :-

P(X\leq14.3)=P(z

Hence, the probability a state highway inspector could select a sample of 49 trucks and find the sample mean to be 14.3 tons or less =0.0062

Melina stocks her fruit stand with organic and non-organic fruits and keeps track of what is sold. The results are shown in the
damaskus [11]

The probability that a randomly selected apple is non-organic is <u>option D)</u> 0.19

<u>Step-by-step explanation</u>:

<u>From the table shown</u>:

  • The probability of total apples = 0.7
  • The probability of apples that are non-organic = 0.14

P(apple to be non-organic)= P(apples that are non-organic) / P(total apples)

⇒ 0.14 / 0.7

⇒ 0.2

⇒ Approximately 0.19 ≈ 0.2

BlackZzzverrR [31]

Given:

Bedroom is a rectangle with length 5 m and width 3 m.

Elena's bedroom door is 0.08 m.

Elena's bed measures 4 cm by 3 cm.

Scale of drawing is 1 to 50.

To find:

The width of door on the scale drawing.

Actual measurements of her bed.

Step-by-step explanation:

Scale of drawing is 1 to 50.

It means, the length of sides in drawing is \dfrac{1}{50} of actual.

Elena's bedroom door is 0.08 m.

1 m = 100 cm

0.08 m = 8 cm

Door on the scale drawing =\dfrac{1}{50}\times 8

                                             =0.16

Therefore, the Door on the scale drawing is 0.16 cm wide.

Elena's bed measures 4 cm by 3 cm on the scale drawing.

Elena's bed actual measurements are

4\times 50=200cm=2m

3\times 50=150cm=1.5m

Therefore, the actual measurements of her bed is 2 m by 1.5 m.
