A survey of a group of seventh graders and a group of teachers at a local middle school asked how many siblings they each have.

The dot plots below show the results. Based on the shape of the two dot plots, which statements correctly compare them? Select three choices. The center of the data for students has a value less than that of the center of the data for teachers. The center of the data is to the right of the dot plot for both teachers and students. There is a greater variation in the data for teachers than for students. Both sets of data cluster around 2. The same number of teachers as students were surveyed.

One hundred sixty people were surveyed and asked if they believed in UFOs, ghosts, and Bigfoot.
HACTEHA [7]

Answer:

Number of people surveyed believed in at least one of these things = 83

Step-by-step explanation:

Given,

Total number of people, n(T) = 160

number of people believe in UFOs, n(U) = 42

number of people believe in ghost, n(G) = 45

number of people believe in Bigfoot, n(B) =21

number of people believe in UFOs and ghost, n(U ∩ G) = 11

number of people believe in Bigfoot and ghost, n(B ∩ G) = 6

number of people believe in UFOs and Bigfoot, n(U ∩ B) = 4

number of people who believe in all, n(U ∩ G ∩ B) = 2

We have asked to draw the Venn diagram and to calculate the number people surveyed believed in at least one of these things .

So, according to Venn diagram,

Number of people surveyed believed in at least one of these things = 25+11+4+2+26+9+6 = 83

Number of people surveyed believed in at least one of these things = 83

Given that f(x) = x2 − 3x + 3 and g(x) = , solve for f(g(x)) when x = 5. −3 1 7 13
Temka [501]
f(x) = x^{2} - 3x + 3 \\
g(x) =  \frac{x - 1}{4} \\
g(5) = \frac{(5) - 1}{4} = 1 \\
f(1) = (1)^{2} - 3(1) + 3 = 1 \\
Therfore, f(g(5)) = 1

PLZZZ HELP DOES ANYONE KNOW HOW TO DO THIS?!?!?<br> Find x and y
yanalaym [24]

According to the figure, I can safely assume that the 10 cm line and 15 cm line are parallel.

Thus, there are two similar triangles, one with the 10 cm bottom and 15 cm bottom, where one triangle is larger by a factor of 15/10 = 3/2

We know that the 8 cm line segment and y both join to create the side of the large triangle.

8cm + y = the side of the large triangle

Multiplying 8cm by 3/2 gives us 12, since we know the large triangle is 3/2 times larger than the smaller one.

8 + y = 12

y = 4 cm

Finding x is going to be a bit different. We know that the 6 cm line and x form the side of the larger triangle, which we know is 3/2 times larger than x.

x + 6cm = ?

The side of the larger triangle is 3/2x, thus

x + 6 = 3/2 x

Subtract both sides by x

6 = 1/2 x

Multiply both sides by 2

12 cm = x

Thus, y = 4 and x = 12.

Let me know if you need any clarifications, thanks!
