Answer: 4
Step-by-step explanation:
We can expect that 4 of the next 20 pies sold will be blackberry pies, based on the proportion of blackberry pies in the recent sample of 15 pies.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
If Tracy's Pie Shop recently sold 15 pies and 3 of them were blackberry pies.
Proportion of blackberry pies = 3/15
Proportion of blackberry pies = 0.2
So, in the recent sample of 15 pies, 20% were blackberry pies.
To estimate how many of the next 20 pies sold should be blackberry pies
Let us assume that the proportion of blackberry pies in the next sample of 20 pies will be similar to the proportion in the recent sample of 15 pies.
Therefore, we can use this proportion to estimate the number of blackberry pies in the next sample of 20 pies:
Number of blackberry pies = 0.2 x 20
Number of blackberry pies = 4
Therefore, we can expect that 4 of the next 20 pies sold will be blackberry pies, based on the proportion of blackberry pies in the recent sample of 15 pies.

۔what set builder notation is = (2,3,5,7,11)this p
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].

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?
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.

If a is inversely proportional to x, a=15 when x=25 find the constant of variation, k
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

they leave a tip of $1.20, the total would be $9.20
Answer:
$9.2
Step-by-step explanation:
Four friends spend 8 dollars. However, they also leave a 15% tip. So, you will have to multiply .15 by 8. However that is not it. After, you have to add the product of that with 8. Which will give you 9.2.

What are the corordinates of point F on a coordinates plane point F is 4 units to the right and 2.5 units
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)
"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."
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.
1/4 + 7/16 =??
Help me please
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
