a seamstress has a piece of cloth that is 3 yards long. she cuts it into shorter lengths of 16inches each. how many shorter piec
NeTakaya

Answer

Find out the how many shorter pieces can a seamstress cut.

To prove

Let us assume that the number of shorter pieces  cut be x.

As given

A seamstress has a piece of cloth that is 3 yards long.

she cuts it into shorter lengths of 16 inches each.

As

1 yards = 36 inches

Now convert 3 yards into inches.

= 3 × 36

= 108 yards

Than the equation becomes

16x = 108

x = \frac{108}{16}

x = 6.75

Therefore the number of shorter pieces be 6 .

In a freefall skydive, a skydiver begins at an altitude of 10,000 feet. during a freefall, the skydiver drops toward earth towar
asambeis [7]

Answer:

{t|0\leq t\leq 50}

Step-by-step explanation:

We are given that

In a freefall skydive, a skydiver begins at an altitude during free fall =10,000 feet

The skydiver drops towards earth at a rate=175 ft/s

The height of the skydiver from the ground can be modeled using the function

H(t)=10000-175t

We have to find the domain of the function for this situation.

When t=0

Then ,H(0)=10,000 feet

From given graph we can see that the value of t  lies  from 0 to 50.

Therefore, the domain of the function for this situation is given by

{t|0\leq t\leq 50}

A study wanted to assess the accuracy of self-reported smoking status. Participants are asked whether they currently smoke or no
HACTEHA [7]

Answer: a) 0.7878, b) 0.8723

Step-by-step explanation:

Since we have given that

                                              Nicotine present      Nicotine absent

Self-reported non smoker                  82                                      14

Self-reported smoker                          12                                      52

(a) What is the sensitivity of the self-reported smoking status?

P(smoker|Nicotine\ present)=\dfrac{52}{52+14}=\dfrac{52}{66}=0.7878

(b) What is the specificity of the self-reported smoking status?

P(Non-smoker|Nicotine\ absent}=\dfrac{82}{82+12}=\dfrac{82}{94}=0.8723

Hence, a) 0.7878, b) 0.8723
