Is the product of 3⅝ x ⅔ greater than or less than 3⅝? explain without multiplying

2 answers:

3 0

So the question is
number times 2/3 is greater than or less than the sasme number
so let's say x
x times 2/3 is greater than or less than x
since 2/3 is less than 1, 2/3 is a fraction,
anything times a fraction will become smaller

therefor
3 and 5/8 times 2/3 is less than 3 and 5/8

the answer is LESS THAN

You are multiplying a number by a fraction, or something that is less than 1. Anytime you multiply a number by a fraction, it will become smaller. Therefore it will be less than.

∠3 and ∠4 are complementary angles.

pantera1 [17]

Complementary angles add up to 90°
m∠4 = 49° then m∠3 = 41°
49 + 41 = 90

The height of a tree in feet over x years is modeled by the function f(x).

Evgesh-ka [11]

If e-the initial hight of the tree, and the function imply some brackets like

f(x)=30/(1+29e-0.5x) then

for every

$0.5x > 29e + 1$

the rate of growth is negative, the maximum growth per unit of time would be 30ft

$x \geqslant 1$

then

$29e < - 0.5$

so the tree couldn't be 2ft tall initially

if the brackets are something like

f(x)=30:(1+29e)-0.5x then the results may differ

Find the standard deviation of the distribution in the following situations. (Round your answers to two decimal places.) (a) MEN

Arturiano [62]

Answer:

a) 15.579

b) 39.019

Step-by-step explanation:

a) For the top 2% the z-value from the z table

z = 2.054

thus,

z = $\frac{\textup{X-Mean}}{\sigma}$

here

X = 132

Mean = 100

thus,

2.054 = $\frac{\textup{132-100}}{\sigma}$

σ = 15.579

b) Using tables, we get for Z = 0.89 the value of 0.8133 and for Z= 0.90 the value of 0.8159

By interpolation, values for 0.815 and we get Z=0.897

thus,

z = $\frac{\textup{X-Mean}}{\sigma}$

here

X = 220

Mean = 185

thus,

0.897 = $\frac{\textup{220-185}}{\sigma}$

σ = 39.019

-(x+3) = 2x-6 what is x

Makovka662 [10]

Answer:

x=1

Step-by-step explanation:

So, first you make sure to multiply the parenthesis by the negative so then it would be,

-x-3=2x-6

Then you add the -3 from the right to the other side

so, -x=2x-3

Then you want all the X variables to one side so you subtract the 2x to both sides.

so, -3x=-3

divide both by -3

x=1
