If you mean that 1/2 is the base of the logarithm then the the answer is (1/2,1)

- because if y = log (base 1/2) x then x = (1/2)^y and x = 1/2 , y = 1 fits this equation

Answer:

Option 2 is right

(1/2,1)

Step-by-step explanation:

Given is a function with graph as

$y=log_{\frac{1}{2} } x$

Here 1/2 is the base

We find that when x=1, log x =0 and hence (1,1/2) does not lie on this graph

(1/2,1)

When x =1/2, f(x) = log of a number to its own base =1

Thus (1/2,1) satisfies this equation and hence lies on the graph

(0,1) is not right because log x is not defined and not finite.

So only option 2 is right

In the data set below, what is the interquartile range?<br> 7<br> 1<br> 5<br> 5<br> 9<br> Submit

Marizza181 [45]

Answer:

Step-by-step explanation:

The interquartile range is the difference between the upper quartile and the lower quartile.

First find the median.

The median is the middle value of the data set arranged in ascending order

1 5 5 7 9 ← data in ascending order

↑ median

The lower quartile is the middle value of the data to the left of the median. If there is not an exact middle then it the average of the values on either side of the middle.

1 5

↑ lower quartile = $\frac{1+5}{2}$ = 3

The upper quartile is the middle value of the data to the right of the median.

7 9

↑ upper quartile = $\frac{7+9}{2}$ = 8

Thus

interquartile range = 8 - 3 = 5

Can somebody plz help answer the number 10’s questions using the diagram from the bottom left side (only if u know how to do thi

Lana71 [14]

Answer:

10a: △ABC is an Equilateral triangle with all acute angles.

10b: △BCD is A scalene triangle with all acute angles.

10c: △BDE is An Isosceles triangle with one obtuse angle.

Step-by-step explanation:

10) Looking at the diagram at the bottom left;

- △ABC has 3 equal internal angles and as such, it means it will have 3 equal angles.

Thus, we can classify it as; Equilateral triangle with all acute angles.

- △BCD has 3 unequal angles. Thus, it's 3 sides are not equal. Also all the angles are less than 90°.

We can classify it as;

A scalene triangle with all acute angles

- △BDE has 2 equal angles and one angle greater than 90°. This means it has 2 equal sides.

Thus, we can classify it as;

- An Isosceles triangle with one obtuse angle.
