Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(18-13)/(8-4)
m=5/4
y-y1=m(x-x1)
y-13=5/4(x-4)

Two barrels contain equal quantities of honey. From one barrel, 37 gallons of honey are drawn. From the other barrel, 7 gallons of honey are drawn. The quantity remaining in one barrel is now seven times that remaining in the other barrel. How much did each barrel contain at first?
Answers
At the start, each barrel has the same amount of honey, so:
Barrel 1 has X gallons
Barrel 2 has X gallons.
from 1, they extract 37 gallos, and from 2 they extract 7 gallons, so now:
Barrel 1 has X - 37
Barrel 2 has X- 7
and now, the quantity in the Barrel 2 is seven times the quantity in the barrel 1, so:
X- 7 = 7*(X - 37)
we need to find X.
X - 7 = 7*X - 37*7 = 7*X - 259
X - 7*X = 7 - 259
-6*X = -252
X = 252/6 = 42
So at the start, each barrel has 42 gallons of honey.

"A supplier of digital memory cards claims that no more than 1% of the cards are defective. In a random sample of 600 memory cards, it is found that 3% are defective, but the supplier claims that this is only a sample fluctuation. At the 0.01 level of significance, test the supplier's claim that no more than 1% are defective."
Answers
Answer:
Both the values fall in the critical region so we reject H0: p ≤ 0.01 and conclude that the results are significantly different from chance identification and it is not a sample fluctuation.
Step-by-step explanation:
1) Formulate the hypothesis
H0: p ≤ 0.01 against the claim Ha: p > 0.01
2) Choose the significance level ∝= 0.01
3) The test statistics under H0 is
z= x -np /√npq ( without continuity correction)
z= x ± 1/2 -np /√npq ( with continuity correction)
4) the critical region is z> ±2.33 because the alternate hypothesis is stated on greater than basis.
5)Computations:
Z= x -np /√npq ( without continuity correction)
Z= 6- 600( 0.03)/√ 600( 0.03)(0.97)
z= - 2.82 ( without continuity correction)
z= x ± 1/2 -np /√npq ( with continuity correction)
Z= (6-0.5)- 600( 0.03)/√ 600( 0.03)(0.97)
z= -12.5/4.1785
z= -0.29915 ( with continuity correction)
6) Both the values fall in the critical region so we reject H0: p ≤ 0.01 and conclude that the results are significantly different from chance identification and it is not a sample fluctuation.

Help me please
Answers
Answer:
4+7/16
Answer is 11/16
Step-by-step explanation:
Transform the expression then calculate
Answer:
11/16
Step-by-step explanation:
First- make sure they have the same denominator (the number located at the bottom)
(the denominator is the least common multiple (LCM) or essentially where the numbers meet up)
^ 4 and 16 meets up at 16.
^7/16 already has 16 as the denominator, however 1/4 does not.
Therefore-
1/4 * 4/4 + 7/16 * 1/1
^ 4/16 + 7/16
(they have the same denominator, therefore when you add you DO NOT change the denominator)
4+7 is 11- and you keep the denominator
11/16 is a number which you can NOT simplify.
Therefore ^ 11/16 is your answer
What are the corordinates of point F on a coordinates plane point F is 4 units to the right and 2.5 units
Answers
Correct Question
What are the coordinates of point F on a coordinates plane point F is 4 units to the right and 2.5 units down.
Answer:
coordinates of point F are (4,2.5)
Step-by-step explanation:
The horizontal line is x axis which is 4 points on coordinate plane.
The vertical line is y axis which is 2.5 points on coordinate plane
the coordinates are written as (x,y)
therefore the coordinates of point F are (4,2.5) as (x,y)
If a is inversely proportional to x, a=15 when x=25 find the constant of variation, k
Answers
Answer:
Step-by-step explanation:
"Inversely proportional to x" in this situation is represented by a = k/x.
Find k:
Let a = 15 and x = 25, then calculate k:
15 = k/25)
Multiplying both sides by 25 yields k = 15(25), or k = 3/5

۔what set builder notation is = (2,3,5,7,11)this p
Answers
Given:
The set is:
[tex]\{2,3,5,7,11\}[/tex]
To find:
The set builder notation for the given set.
Solution:
Consider the given set:
[tex]S=\{2,3,5,7,11\}[/tex]
The element of given set are 2, 3, 5, 7, 11 and so on. These area the prime numbers.
If x defines each element of the set then x must belongs to P which is the set of prime numbers. So, the given set can be written as
[tex]S=\{x|x\in P\}[/tex]
Therefore, the set builder notation for the given set is [tex]\{x|x\in P\}[/tex].
Nancy works at Yogurty's for $5.35 an hour. Last week, she worked 30 hours.
a) How much did she earn?
b) Nancy received a 25¢/hour raise this week. She worked 25 hours. How much did she earn?
Answers
Answer b) $140
$160.50
explanation:
she worked for 30 hours so that means she earned $5.35 per hour. so all you have to do here is $5.35 x 30 which gives you $160.50.
Answer for B:
$140
explanation:
25¢ is the same as $0.25 so first of all, add 0.25 onto $5.35 which gives you $5.60.
Now, (this is just the same equation as part A but with different numbers), since she earns $5.60 per hour and worked 25 hours, all you have to do it $5.60 x 25 which gives you $140.
Hope this helps :)
