Answer:

Step-by-step explanation:

Correct option is A)

let the number be x.

∴75% of x=15

∴

100

×x=15

∴x=15×

∴x=20

The value of x is 20.

Andreyy89

Answer:

B. 21, 28, 33, 41, 81

Step-by-step explanation:

Data : 21, 22, 22, 24, 24, 24, 24, 25, 26, 26, 26, 26, 26, 26, 26, 26, 26, 27, 27, 27, 27, 28, 28, 28, 28, 29, 29, 29, 29, 29, 30, 30, 30, 30, 30, 30, 31, 31, 31, 32, 32, 33, 33, 33, 33, 33, 33, 33, 34, 34, 34, 34, 34, 35, 35, 35, 35, 35, 37, 37, 37, 37, 38, 38, 38, 39, 39, 39, 41, 41, 41, 41, 42, 42, 44, 45, 45, 45, 47, 49, 49, 54, 60, 60, 61, 61, 61, 62, 62, 74, 81

Five number summary includes :

1. Minimum vale

2. First Quartile

3. Median : mid value of the given data is 46th term = 33

4.Third Quartile

5.Maximum value

Solution :

1. Minimum vale : smallest value of data = 21

2. First Quartile: median of the data (first number to the actual median) i.e. from 1st term to 46th term

Median for even number of terms : $\frac{\frac{n}{2}th+(\frac{n}{2}+1)th}{2}$

n = 46

so, median = $\frac{\frac{46}{2}th+(\frac{46}{2}+1)th}{2}$

= $\frac{23th+24th}{2}$

= $\frac{28+28}{2}$

= $\frac{56}{2}$

= $28$

Thus first quartile = 28

3. Median : mid value of the given data(ages of 91 women) is 46th term = 33

4.Third Quartile :median of the data (46th number[actual median] to the 91th)

Median for even number of terms : $\frac{\frac{n}{2}th+(\frac{n}{2}+1)th}{2}$

n = 46

so, median = $\frac{\frac{46}{2}th+(\frac{46}{2}+1)th}{2}$

= $\frac{23th+24th}{2}$

= $\frac{41+41}{2}$

= $\frac{82}{2}$

= $41$

Thus third quartile = 41

5.Maximum value : highest value of data = 81

Thus the five number summary is 21, 28, 33, 41, 81

Hence Option B is correct

Domain and Range: determine the domain and Range for each graph

bija089 [108]

Given:

The graph of a function.

To find:

The domain and range of the given graph.

Solution:

Domain is the set of x-values or input values.

From the given graph it is clear that, the graph is defined for the interval (-4,4).

But there is a closed circle at x = -4 and an open circle at x = 4. It means, -4 is included and 4 is not included in the solution set.

Domain: [-4,4)

Domain: $-4\leq x$

Range is the set of y-values or output values.

From the given graph it is clear that, the output values are lie in the interval (-3,4).

But there closed circle at x = -3 and x = 4. It means, -3 and 4 are is included in the set of output values.

Range: [-3,4]

Range: $-3\leq y\leq 4$

Therefore, domain is $-4\leq x$ and range is $-3\leq y\leq 4$ .

How would tell someone how to write 10 power to -12 as a fraction?

Alisiya [41]

You would write it as (1/10^12)

any negative exponent does the same thing

ex: x^-1 turns into (1/x^1)
