Answer: Convenience sampling method.

Step-by-step explanation:

  • A convenience sampling method is one of the main kinds of non-probability sampling methods. It is made up  by researcher according to his or her accessibility  i.e. the researcher select the participants or the items from the population that are easy to reach.

The given statement shows that the quality control analyst inspects the first 100 items produced that day i.e. he selected the items according to his convenience.

Based on the given scenario above wherein the quality control analyst just inspects the first 100 items produced that day in order to avoid staying after work, the sampling method that she used is the CONVENIENCE SAMPLING METHOD. Hope this helps.

Find the value of x (sines and cosines)
Sav [38]
You would begin by choosing which trigonometric function to use. 
In this case, you would use sine.

Sine is opposite over hypotenuse. 
Opposite of the 35 degree angle is 18, and you want to find the hypotenuse which is x.

sin(35) = \frac{18}{x} (multiply x to both sides)
x sin(35) = 18 (divide sin(35) to both sides)
x = 31.38204...

So, therefore x = 31.38. I don't know what decimal point you're supposed to round to, so I'm gonna guess the hundredths place. :)

(a)
Vika [28.1K]

Answer:

(a) Percentage of girls = 55\frac{5}{7}

(b) Percentage of boys = 44\frac{2}{7}

Step-by-step explanation:

To find percentage, we multiply the fraction out of the total by 100%.

Percentage of girls = \frac{780}{1400} × 100%

                                = 55\frac{5}{7}

Percentage of boys = \frac{1400-780}{1400} × 100%

                                 = 44\frac{2}{7}

Use the image to match the arc/angle measure.
IrinaK [193]

Answer:

The following measurements are:

m\angle{STR}=23^\circ (Option #4)

m{QT}=142^\circ (Option #7)

mST=134^\circ (Option #5)

mRQ=38^\circ (Option #2)

Step-by-step explanation:

To begin, we can find the measure of \angle{STR} by applying the inscribed angle theorem: an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

Since the intercepted arc (RS) is 46 degrees, we have:

46=2\theta\\23=\theta

Next, we can find the measure of arc QT using the same theorem. So,

QT=2(71)\\QT=142

Notice that the chord RT is actually a diameter. From the theorem about the inscribed angle including a diameter, we know that the intercepted arc will have a measure of 180^\circ. Since the arc ST is part of the arc RST, and we know RS is 46^\circ, we can set up and solve this equation:

RST = RS + ST\\180 = 46 + ST\\134 = ST

We can use the same idea to find RQ. We know that RQT is 180^\circ and QT is 142^\circ, so:

RQT = RQ + QT\\180 = RQ + 142\\38 = RQ
