Find the weighted mean

Mathematics
1 answer:
Nataly_w [17]3 years ago
3 0

Answer:

10.1

Step-by-step explanation:

weighted mean = sum of the multiplication of frequency and value /sum of frequency

sum of frequency  = 5 + 5 + 5 + 21 = 36

sum of the multiplication of frequency and value = (16 x 5) + (20 x 5) +  (16 x 5) + ( 5 x 21) = 365

365/36 = 10.1

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Given f(x)= square root x and g(x) = lxl, which is the graph of (fog)(x)
marin [14]

Answer:

drawing the graph of f(g(x))=\sqrt{|x|}

The graph is attached in the images below.

Option A is correct option.

Step-by-step explanation:

We are given:

f(x)=\sqrt{x} and g(x)=|x|

We need to find graph of  (fog)(x)

We know that (fog)(x)= f(g(x))

Placing x=g(x) i,e x=|x|

(fog)(x)= f(g(x))\\f(g(x))=\sqrt{|x|}

Now, drawing the graph of f(g(x))=\sqrt{|x|}

The graph is attached in the images below.

Option A is correct option.

Find the length of ST In the kite.
kifflom [539]

Answer:

1.29

Step-by-step explanation:

The diagonals of a kite are perpendicular.

Angles QRT and SRT are congruent.

In right triangle STR, for angle TRS, ST is the opposite leg, and SR is the hypotenuse. The sine ratio relates the opposite leg to the hypotenuse, so we use the sine ratio to find the length of segment ST.

sin <TRS = opp/hyp

sin <TRS = ST/SR

sin 23 deg = ST/3.3

ST = 3.3 * sin 23 deg

ST = 1.29
