PLEASE HELP!!! I WILL RATE BRAINLIEST TO THE FASTEST AND CORRECT ANSWER!!!

Answers

Answer 1
Not easy:

- 4 < x^4 + 4x^2 ---> 0 < x^4+4x^2+4 = (x^2+2)^2, so it is always positive. Always satisfied. Curious ...

Now the other one:

x^4+4x^2<21 --> x^4+4x^2-21 < 0 --> (x^2+2)^2 - 25 < 0

(x^2+2)^2<25 ->>> x^2+2 < 5 ---> x^2 <3,

So -sqrt(3)<x<sqrt(3) is the answer! Brainliest?

Find 3 consecutive integers whose sum is 180

Answers

60. 60 + 60 + 60 = 180.
x + (x+1) + (x+2) + (x+3) = 180
4x + 6 = 180
4x = 174
x = cannot be an even integer
If they were consecutive even integers,
x + (x+2) + (x+4) + (x+6) = 180
4x + 12 = 180
4x = 168
x = 42, 44, 46, 48

What is the slope of the line represented by the equation y = – 2/3- 5x?

A. -5
B. -2/3
C.2/3
D. 5


PLS HELP TY

Answers

Answer:

Option A The slope of the line is [tex]-5[/tex]

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

[tex]y=mx+b[/tex]

where

m is the slope

b is the y-intercept

we have

[tex]y=-\frac{2}{3}-5x[/tex]

Rewrite

[tex]y=-5x-\frac{2}{3}[/tex]

therefore

[tex]b=-\frac{2}{3}[/tex] -----> the y-intercept

[tex]m=-5[/tex] ------> slope


a set of data can have no mode true or false

Answers

If there is NO data value or data values that occur most frequently, we say that the set of data values has no mode.

True, A set of data can indeed have no mode. In statistics, the mode represents the value(s) that appear most frequently in a dataset.

However, there are scenarios where no value occurs more frequently than others, resulting in a lack of a mode. This can happen in several situations. For example, in a uniform distribution where all values occur with equal frequency, or in a dataset with no repetition of values (each value occurs only once). Additionally, if the data is continuous and does not have distinct categories or intervals, it may not have a mode. In summary, while a mode is a common descriptive statistic, it's not a requirement for every dataset, and some datasets do indeed have no mode.
