Cost of Apples
10
9
D
Total Cost in Dollars
1 2 3 4 5 6 7 8 9
Pounds of Apples
At which store is the cost of apples the least?
Answer:
The store is the cost of apples the least is store A
Step-by-step explanation:
On the graph the lowest line is A which means the prices are lower for the pounds of apples.
At Store A is the cost of apples the least. This is because it always has the lowest price for each pound compared to the other lines.
PLEASE HELP IM DESPERATE IVE BENN WORKING ON THIS FOR THE PAST 48 HOURS I AM MARING BRAINIEST!: A constructor is measuring the perimeter of a plot for a building. 31% of the way around the perimeter, the constructor has measured 14 meters. How far around is the entire perimeter? Round your answer to the nearest hundredth.
Answer:
P = 45.16 meters
Step-by-step explanation:
Let the perimeter by P
31% of P is 14 meters
P*31% = 14 meters
Change to decimal form
P*.31 = 14
Divide each side by .31
P*.31/.31 = 14/.31
P =45.16129032
Rounding to the nearest hundredth
P = 45.16 meters

Step-by-step explanation:
The FDA regulates that fresh Albacore tuna fish contains at most 0.82 ppm of mercury. A scientist at the FDA believes the mean amount of mercury in tuna fish for a new company exceeds the ppm of mercury. The hypotheses are: H0:µ = 0.82 H1:µ > 0.82 What is a type II error in the context of this problem? A. The fish is accepted by the FDA when in fact it had more than 0.82 ppm of mercury. B. The fish is accepted by the FDA when in fact it had less than 0.82 ppm of mercury. C. The fish is rejected by the FDA when in fact it had less than 0.82 ppm of mercury. D. The fish is rejected by the FDA when in fact it had more than 0.82 ppm of mercury.
Answer:
Option A
Step-by-step explanation:
A type II error occurs when the researcher fails to reject the bull hypothesis when it is false.
In this study, the
null hypothesis is H0:µ = 0.82 while the alternative hypothesis is H1:µ > 0.82
Thus, the type II error will be that the fish is accepted by the FDA when in fact it had more than 0.82 ppm of mercury.

Answer:
The answer is "[tex]\bold{y=4x+17}[/tex]".
Step-by-step explanation:
In the given statement the graph is missing. So, the correct solution to this question can be described as follows:
Given
graph point: [tex]\bold{(2, 25)}[/tex]
Line points: [tex]\bold{(0,10), \ \ and \ \ (10,50)}[/tex]
The Formula of slope:
[tex]\boxed{M= \frac{y_2-y_1}{x_2-x_1}}\\\\\Rightarrow x_1= 0, y_1= 10 \\\\\Rightarrow x_2= 10, y_2=50\\\\\Rightarrow M= \frac{50-10}{10-0}\\\\\Rightarrow M=\frac{40}{10}\\\\\Rightarrow M= 4\\[/tex]
Assuming point: (x,y)
Graph point: (2,25)
M= 4
Equation:
[tex]\Rightarrow \frac{25-y}{2-x}=4\\\\\Rightarrow 25-y=4(2-x)\\\\\Rightarrow 25-y=8-4x\\\\\Rightarrow y= 4x-17\\[/tex]
URGENT!! A 16 inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece is 5 times as long as the first piece. If x represents the length of the first piece, find the lengths of all three pieces. what is the length of the first piece, the second piece, and third piece?
Answer:
Step-by-step explanation:
let length of first piece = x in
length of second piece = 2x
length of third piece = 5x
x+2x+5x= 16
8x =16
x =16/8
x=2
length of :
first piece =2 inches
second piece = 4 inches
third piece = 10 inches..
please mark me as the brainliest..
Answer:
2, 4, 10 in
Step-by-step explanation:
The first piece is x thus the second piece is 2x ( twice as long as first ) and
the third piece is 5x ( five times as long as the first )
Add the 3 together and equate to 16
x + 2x + 5x = 16, that is
8x = 16 ( divide both sides by 2 )
x = 2
Thus
first piece = x = 2 in
second piece = 2x = 2 × 2 = 4 in
third piece = 5x = 5 × 2 = 10 in
Drag vertices B and C of the triangle. Then, conjecture about the relationship between angle measures and side lengths in a triangle.
If the angle measure is the largest of the triangle, what do you know about the side opposite?
It is the length.
If a side is the shortest of the triangle, what do you know about the angle opposite that side?
It is the degree measure
Answer:
1. longest
2. smallest
For the triangle mentioned here, the following is what will be obtainable based on the conjecture about relationship between sides and angle measures of a triangle:
You will know that for the largest angle measure, the side opposite the angle will be the longest side.You will know that for the shortest side in the triangle, the angle opposite it will be the smallest angle measure.Recall the conjecture about the relationship between the sides and angles of a triangle:
The largest angle in a triangle always faces the longest side of the triangle.The smallest angle in a triangle always faces the shortest side of the triangle.Thus, for the triangle mentioned here, the following is what will be obtainable based on the conjecture about relationship between sides and angle measures of a triangle:
You will know that for the largest angle measure, the side opposite the angle will be the longest side.You will know that for the shortest side in the triangle, the angle opposite it will be the smallest angle measure.Learn more here:

The arithmetic sequence a; is defined by the formula:
a1=4
ai = ai-1 + 11
Find the sum of the first 650 terms in the sequence.
Answer:
The sum of the first 650 terms of the given arithmetic sequence is 2,322,775
Step-by-step explanation:
The first term here is 4
while the nth term would be ai = a(i-1) + 11
Kindly note that i and 1 are subscript of a
Mathematically, the sum of n terms of an arithmetic sequence can be calculated using the formula
Sn = n/2[2a + (n-1)d)
Here, our n is 650, a is 4, d is the difference between two successive terms which is 11.
Plugging these values, we have
Sn = (650/2) (2(4) + (650-1)11)
Sn = 325(8 + 7,139)
Sn = 325(7,147)
Sn = 2,322,775

Which linear inequality is represented by the graph?
y > Two-thirdsx – 2
y < Two-thirdsx + 2
y > Two-thirdsx + 1
y < Two-thirdsx – 1
The inequality that represents the graph is y < (2/3)x - 1. Then the correct option is D.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The two points are given below.
(3, 1) and (-3, -3)
The inequality is given below.
(y + 3) < [(1 + 3) / (3 + 3)](x + 3)
y + 3 < (2/3)(x + 3)
y + 3 < (2/3)x + 2
y < (2/3)x - 1
The inequality that represents the graph is y < (2/3)x - 1. Then the correct option is D.

Answer:
x = 3/2 x = -5/2
Step-by-step explanation:
(2x+3) ^2 - 4(2x+3) - 12 = 0
Let m = 2x+3
m^2 - 4m - 12 = 0
Factor
(m-6) (m+2) = 0
Using the zero product property
m-6 = 0 m+2 =0
m = 6 m = -2
Substitute m = 2x+3 back into the equation
2x+3 = 6 2x+3 = -2
2x = 3 2x = -5

Answer:
The data table is attached below.
Step-by-step explanation:
The average of a set of data is the value that is a representative of the entire data set.
The formula to compute averages is:
[tex]\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}[/tex]
Compute the average for drop 1 as follows:
[tex]\bar x_{1}=\frac{1}{3}\times[10+11+9]=10[/tex]
Compute the average for drop 2 as follows:
[tex]\bar x_{2}=\frac{1}{3}\times[29+31+30]=30[/tex]
Compute the average for drop 3 as follows:
[tex]\bar x_{3}=\frac{1}{3}\times[59+58+61]=59.33[/tex]
Compute the average for drop 4 as follows:
[tex]\bar x_{4}=\frac{1}{3}\times[102+100+98]=100[/tex]
Compute the average for drop 5 as follows:
[tex]\bar x_{5}=\frac{1}{3}\times[122+125+127]=124.67[/tex]
The data table is attached below.
The average of the numbers in the data table will be 10, 30, 59.33, 100, and 124.67.
How to explain the data table?The average for drop 1 will be:
= 1/3 × (10 + 11 + 9)
= 10
The average for drop 2 will be:
= 1/3 × (29 + 31 + 30)
= 30
The average for drop 3 will be:
= 1/3 × (59 + 58 + 61)
= 59.33
The average for drop 4 will be:
= 1/3 × (102 + 100 + 98)
= 100
The average for drop 5 will be:
= 1/3 × (122 + 125 + 127)

1 and 2/3
Step-by-step explanation:
how many cylindrical glasses 6cmin diameter and 10cm deep can be filled from cylindrical jug 10cm in diameter and 18cm deep
Answer:
Step-by-step explanation:
So we need to divide the volume of the cylindrical glasses by the cylindrical jugs to see how many we can fill.
The equation to find the volume of a cylinder is Height*Area of Circle
To find the area of a circle is: [tex]\pi r^{2}[/tex]
In this senario "r" (radius) is 3 (d/2)
Volume for cylindrical glass:
hx[tex]\pi r^{2}[/tex]
= 10x 3.14x 3^2
= 10x3.14x 9
= 282.6[tex]cm^{3}[/tex]
Now for the cylindrical jug: r= 5 and h=18
hx[tex]\pi r^{2}[/tex]
= 18x3.14x5^2
= 18x3.14x25
= 1413[tex]cm^{3}[/tex]
Now finally we divide them:
1413/282.6
= 5
So they can fill 5 cylindrical glasses :)
