3x-4y=12

y=mx+b

slope is also m

b= y-intercept

move 3x to the other side

sign changes from +3x to -3x

3x-3x-4y=-3x+12

-4y=-3x+12

divide both sides by -4

-4y/-4=-3/-4+12/-4

Cross out -4 and -4, divide by 4 and then becomes -1*-1*y=y

12/-4=-3

y=3/4x-3

Answer: slope is 3/4

he pulse rates of 179 randomly selected adult males vary from a low of 43 bpm to a high of 115 bpm. Find the minimum sample size
malfutka [58]

Answer:

97

Step-by-step explanation:

Given that:

Low = 43bpm

High = 115 bpm

Error = 3

α = 90%

To find the range estimate :

Standard destviation = (high - low) / 4

Standard deviation = (115 - 43) / 4

Standard deviation = 72/4 = 18

The sample size,(n) :

n = [(Zα/2 * sd)/E] ²

2 - tail = (Zα/2) = 1.645

[(Zα/2 * sd)/E] ² = [(1.645 * 18) / 3]² = (29.61/3)²

= 97.41

Sample size = 97

You randomly pick two numbers from 1 to 9 (including 1 and 9). A number that is chosen once could be chosen again. If at least o
Mnenie [13.5K]
Assume that you only include whole numbers (1,2,3,4,5,6,7,8,9) and not 3.5 and such
so if 1 is odd and less than 5 then it is
1 or 3, since 5 isn't included
then the other number, to be less than 5 when added,
must be
1+x<5
3+x<5
solve each
1+x<5
subtract 1
x<4
set of answers are 1,2,3

3+x<5
subtract 3
x<2
set of answer is 1
so the possible numbers are
1,2,3
that is 3 numbesr out of 9 so
probability=(total desired outcomes)/(total possible outcomes) so
disred outcomes=3
total possible=9
3/9=1/3
the probabiltiy is 1/3

a tool rental cost $0.65 per minute. if the total bill for the rental was $18.20 then for how many minutes was the tool used?
REY [17]
Wouldn't you do 18.20 divide that by .65 & get 28. So the tool was used for 28 minutes
