One more than four times a number b is 17

Alinara [238K]

i guess i got the answer ...

well..... four times a number b = 4×b = 4b

one more than is +1

and this = 17

now we need to put it all together and forma an equation .... so .. it will be

4b + 1 = 17

4b = 17 - 1

4b = 16

b = 16/4

∴ b = 4

In a certain lake, trout average 12 in. in length with standard deviation 2.75 in. and the bass average 4 lb. in weight with sta

NISA [10]

Answer:

The bass fish was the better catch

Step-by-step explanation:

From the question we are told that

The population mean for trout is $\mu_1 = 12 \ in$

The standard deviation is $\sigma_1 = 2.75 \ in$

The population mean for base is $\mu _2 = 4 \ lb$

The standard deviation is $\sigma_2 = 0.8 \ lb$

The number of trout caught $x_1 = 18$

The number of bass caught $x_2 = 6$

Generally z-value(standardized value ) for the of number trout caught is mathematically represented as

$z_1 = \frac{x_1 - \mu_1}{\sigma_1 }$

substituting value

$z_1 = \frac{18 - 12}{2.75 }$

$z_1 = 2.18$

Generally z-value(standardized value ) for the of number bass caught is mathematically represented as

$z_2 = \frac{x_2 - \mu_2}{\sigma_2 }$

substituting value

$z_2 = \frac{6 - 4}{0.8 }$

$z_2 = 2.5$

From our calculation we see that $z_2 > z_1$

The fish that was the better catch is the bass fish

Which relation is also a function?

dalvyx [7]

A function will not have any repeating x values...they all have to be different. They can have repeating y values, just not the x ones.

so ur sets of numbers are all set up like (x,y). Now look through ur answer choices and which one has all different x values ? That will be ur function.

ur answer is : { (-4,-3), (0,-3), (1,-3), (4,-3)}.....and as u can see, all the x values {-4,0,1,4} are different.
