How can you represent and summarize data in a dot plot?

1 answer:

5 0

In a dot plot, each one of the dots represents a value in the data set. When there are multiple values at a particular number, the dots just get stacked on top of each other. Using the dots in the plot, you can find the mean, median, mode or any other statistic that you need to summarize the data.

F(n)=−11+22(n−1), left parenthesis, n, right parenthesis, equals, minus, 11, plus, 22, left parenthesis, n, minus, 1, right pare

prisoha [69]

Answer:

$a_1 = -11\\\\a_n = a_{(n - 1)} + 22$

Step-by-step explanation:

An arithmetic sequence is generally given as:

f(n) = a + (n - 1)d

where a = first term and f(n) = nth term, d = common difference

The explicit formula given is:

f(n) = 11 + 22(n - 1)

The recursive formula is made of two statements, the first term and the formula showing how successive terms are related.

Mathematically, it is given as:

$a_1 = a\\\\a_n = a_{(n - 1)} + d$

Therefore, the recursive formula is:

$a_1 = -11\\\\a_n = a_{(n - 1)} + 22$

In a class of 80 students ,53 study art ,60 study biology ,36 study art and biology ,34 study art and chemistry ,6 study biology

d1i1m1o1n [39]

Answer:

The missing part is the intersection of all 3, label it x

Now look at the intersection of A and C, it must be 34.

But you already have x accounted for in the intersection of all 3.

So label the part in A and C, but not B as 34-x

36 study A and B, so the part of A and B, but not C is

36-x

Given that 53 study Art, in the A only part we can put

53-(36-x) - (34-x) -x = x - 17

6 study B only, put that in.

So the missing part of B is 60 - 6 - (36-x) - x

= 18

18 study B , but not C, so they could be in A

label the part of A and B, but not C as 18

BUT, we already know that A and B, not C, is 36-x

So 36-x = 18

X=18

I think we are done

Find the base circumference of a cone with height 10 cm and volume 90π cm3 .

Leni [432]

Answer:

Answer is circumference =32.64

Step-by-step explanation:

$given \\ volume \: of \: cone \: = 90\pi \: {cm}^{3} \\ and \: height = 10 \: cm \: \\ to \: find: circumference \\ by \: the \: given \: data \\ volume \: of \: cone = 90\pi \\ \frac{1}{3} \pi {r}^{2} h = 90\pi \\ cancelling \: \pi \: which \: is \: common \: \\ we \: get \\ \frac{1}{3 } {r}^{2} h = 90 \\ we \: know \: that \: h = 10 \\ on \: substituting \: we \: get \\ \frac{1}{3} {r}^{2} \times 10 = 90 \\ dividing \: by \: 10 \: on \: both \: sides \: we \: get \\ \frac{1}{3} {r}^{2} = 9 \\ {r }^{2} = 27 \\ r = 3 \sqrt{3} \\ we \: know \: that \: circumference \: = 2\pi \: r \\ = 2 \times \frac{22}{7} \times 3 \sqrt{3} \\ on \: solving \: the \: above \: mentioned \: we \: get \\ \\ \: = 32.64$
