The package of a particular brand of rubber band says that the bands can hold a weight of 7 lbs. Suppose that we suspect this mi

zzz [600]

Answer:

False this value is very likely to find in this distribution

Step-by-step explanation:

With mean 7 ( μ ) and standad deviation (σ ) 2 we can observe, value 6.6 is close to the lower limit of the interval

μ ± 0,5 σ 7 ± 1 in which we should find 68,3 % of all values

(just 6 tenth to the left)

And of course 6.6 is inside the interval

μ ± 1 σ where we find 95.7 % of th value

We conclude this value is not unlikely at all

The value -2 is a lower bound for the zeros of the function shown below f(x)=4x^3-12x^2-x+15

NISA [10]

We are given

The value -2 is a lower bound for the zeros of the function shown below f(x)=4x^3-12x^2-x+15

So, firstly, we will find value of f(x) at x=-2

we will plug x=-2 into f(x)

we get

$f(x)=4x^3-12x^2-x+15$

we will plug x=-2

$f(-2)=4(-2)^3-12(-2)^2-(-2)+15$

now, we can simplify it

$f(-2)=-32-12\cdot \:4-\left(-2\right)+15$

$f(-2)=-63$

so,

$f(-2)=-63$

we know that any zeros always lies between positive and negative value

Here , we got f(-3)=-63 ...which is negative value

so, this is lower bound

Hence , this is TRUE

What is the value of x

Ede4ka [16]

Answer:

x = $\frac{18}{5}$

Step-by-step explanation:

First we have to distribute:

Multiply $\frac{1}{3}$ with 15 and x

$\frac{1}{3} x$ + 5 = 2x - 1

So to eliminate the fraction we have to multiply by the denominator which is 3.

$\frac{1}{3}x*\frac{3}{1}$ + 5(3) = 2x(3) - 1(3)

1x + 15 = 6x - 3

So Subtract 6x from both sides

-5x + 15 = -3

Subtract 15 from both sides

-5x = -18

Then divide both sides by -5. The negatives cancel themselves out.

x = $\frac{18}{5}$

What is the next number in the pattern of 12 24 72 288

ExtremeBDS [4]

The next number is 1440.

Here is the pattern:

12*2=24

24*3=72

72*4=288

So, you have to multiply 288 by 5, which will get you the answer 1440.
