6. Which of the following is true about the

Gnom [1K]

C.
Y=mx + b is the formula (M being slope, and B being the y intercept) always start by going up or down by what the y-intercept number is, if it’s -9 you go down the y axis 9 numbers from the origin (0,0) and slope (m) is always better put in a fraction-5x is better put in -5/1x
Think of the top number of the fraction as ‘up/down’ and the bottom number as ‘over’ if the top number is negative you will go down from the y-intercept number that many times, the bottom number is how many spots you go over from that number , it is always to the right.

Your first assignment at El Smello Perfume Co. is to determine the proper setting for filling the bottles. The company wishes to

SCORPION-xisa [38]

Answer:

The answer is "96.864 ml".

Step-by-step explanation:

In this question, the formula of $\bold{CI = X \pm t \times s}$ .

( where X is the mean, t is the coefficient, and s is the mean difference error)

As a result, only 2.5% of containers might include less than 100 ml of volume, its trust coefficient could indeed be used in accordance with 95%, which is $t=1.96$ .

And it can take $\pm \ 1.6 \ ml$ to have been the full value the standard infinite: $\to CI = 100 \pm (1.96 \times 1.6) \\\\$

$= 100 \pm (3.136) \\\\$

Consequently, if the standard error is $\pm \ 1.6 \ ml$ , a similar amount should be used to fill

$= 100 - 3.136 \\\\= 96.864 \ \ mL$

What is 1/5 ÷ 5<br> someone pls help me

Elena-2011 [213]

Answer: 1/25 or 0.04

Step-by-step explanation:

1/5 divided by 5 for the whole number you have to turn it to a fraction so you would do 5/1

THEN: it becomes 1/5 divided by 5/1 but you have to do the inverse so the inverse of division is multiplying and you will cross multiply so 5*5= 25 and 1*1=1 therefor the final answer is 1/25

3/28 of the animals are birds. 4/15 are birds of prey. What fraction of the animals are birds of prey.

vova2212 [387]

Let's call animals "a", and birds "b", birds of prey, "p"

so, b= $\frac{3}{28} a$

and p= $\frac{4}{15} b$
what;s the relation of p to a?

we substitude b into the last one:

and p= $\frac{4}{15}* \frac{3}{28} a$
so:
p= $\frac{4*3}{15*28} a$

p= $\frac{4*1}{5*28} a$

p= $\frac{1*1}{5*7} a$

p= $\frac{1*1}{35} a$

which is the answer!
