Answer: 2.8
Step-by-step explanation:
Given Data:
Money spent by Paula for red bell peppers = $2.56
Money spent by Paula on green bell peppers = $1.92
Both pepper cost = $1.60/ pound
Therefore:
Total pounds of bell peppers bought by Paula
= cost of green bell pepper + red red bell pepper / price/pound
= $2.56 + $1.92 / $1.60
= $4.48 / $1.60
= 2.8 pounds
Paula bought 2.8pounds of pepper

I think the most common are 7/8.
a, b , c and d are four integers.
their mean is 8.
their mode is 7.
their median is 7.5.
find the four integers
The four integers are 7, 7, 8, 10
What are the integers ?
Four integers are a, b, c, d
Mean = Sum of integers/Total number of integers
= (a+b+c+d)/4
According to the question,
Mean = 8
i.e. (a+b+c+d)/4 = 8
⇒ a+b+c+d = 32 ......(1)
Median (for even no. of integers) = ([tex]\frac{n}{2}^{th} +(\frac{n}{2}+1)^{th}[/tex] term)/2
= (2nd+3rd term)/2
= (b+c)/2
According to the question,
Median = 7.5
i.e. (b+c)/2 = 7.5
⇒ b+c = 15 .....(2)
We know that, most frequent data is the mode.
So, mode = 7 means the number 7 occurs most frequently.
7 is not more than 2 times, because if 7 occurs 3 times, then 2nd & 3rd term will be 7 & median will be (7+7)/2 i.e. 7, so 3rd term must be larger than 7 to adjust the median value, which is 7.5
Then 1st two integers are 7 & 7
i.e. a = b = 7
Now, from (2), b+c = 15
⇒ 7+c=15
⇒ c =15-7
⇒ c = 8
Now, from (1) we get, a+b+c+d = 32
⇒ 7+7+8+d = 32
⇒ 22+d = 32
⇒ d = 32-22
⇒ d = 10
So, a = 7, b = 7, c = 8, d = 10

2. Sumara Kato's savings account has a balance of $1663. After 19 years, how much interest
will she have eamed if her rate is 5.5% compounded annually?
Answer:
Step-by-step explanation:
interest = Amount - principal
A = P(1+r)^t
r = 5.5% = 5.5/100 = 0.055
A = 1663(1+ 0.055)^19
A = 1663 (1.055)^19
A = 4,599.270812203411
Let’s say A = 4,599
interest = 4,599-1663 = 2,936

volume of cone with radius of 6 and heights of 8
Hey there! I'm happy to help!
To find the volume of a cone, you multiply the base by the height and then divide by three.
The base of a cone is a circle. To find the area of a circle, we square the radius and then multiply it by pi (we will use 3.14). Let's find the base below.
6²=36
36×3.14=113.04
Now, we multiply by the height.
113.04×8=904.32
Finally, we divide by three.
904.32÷3=301.44
Therefore, the volume of this cone is about 301.44 units cubed.
Now you can find the area of cones! I hope that this helps! Have a wonderful day!

There's some unknown (but derivable) system of equations being modeled by the two lines in the given graph. (But we don't care what equations make up these lines.)
There's no solution to this particular system because the two lines are parallel.
How do we know they're parallel? Parallel lines have the same slope, and we can easily calculate the slope of these lines.
The line on the left passes through the points (-1, 0) and (0, -2), so it has slope
(-2 - 0)/(0 - (-1)) = -2/1 = -2
The line on the right passes through (0, 2) and (1, 0), so its slope is
(0 - 2)/(1 - 0) = -2/1 = -2
The slopes are equal, so the lines are parallel.
Why does this mean there is no solution? Graphically, a solution to the system is represented by an intersection of the lines. Parallel lines never intersect, so there is no solution.
Scarlett bought 9 chicken wings for $3. What was the cost of the wings in wings per dollar? Express your answer in simplest form.
Answer:
3
Step-by-step explanation:
To find how much you can get for one dollar, you have to divide 9 by 3. If you have to find how many units can you get for one dollar, (you need to divide the larger number by the smaller)
Divide 9 by 3.
9/3=3
So, with $1, you can get 3 chicken wings.
Find the slope and y-intercept of the graph of the linear equation.
12. y= 4x
Answer:
Slope = 4, y-intercept = (0,0)
Step-by-step explanation:
This problem is written in slope-intercept form. Meaning it is in the form y=mx+b. "M" is the slope, and "B" is the y-intercept. With that information, we easily see that 4 is the slope of the graph (it will go up 4 points for everyone one point it goes right). It seems that there is no y-intercept though, that is because we are expected to know that y=4x is the same as y=4x+0. Meaning, the problem can also be written this way and the y-intercept must be 0.

Is (4, 2) a solution of the system?
Choose 1 answer:
А)
Yes
B
No
Answer:
B. No
Step-by-step explanation:
In order to see if (4, 2) is a solution, we have to plug 4 in for x and 2 in for y in the equations. If it's a true statement, then we know that the point is a solution.
One of the equations is y = 3x + 4. Plug in 4 for x and 2 for y:
y =? 3x + 4
2 =? 3 * 4 + 4
2 =? 12 + 4
2 ≠ 16
Thus, we know that (4, 2) is not a solution and the answer is B.

Find the percent of all values in a normal distribution for which z ≤ 1.00, to the nearest tenth of percent.
Answer:
84.1% of all values in a normal distribution have z ≤ 1.00.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
The percent of all values in a normal distribution for which z ≤ 1.00.
This is the pvalue of Z = 1.
Z = 1 has a pvalue of 0.8413.
Converting to percentage, to the nearest tenth.
84.1% of all values in a normal distribution have z ≤ 1.00.

The radius of a cylindrical water tank is4.5ft , and its height is12ft . What is the volume of the tank? Use the value for , and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Answer:
[tex]763 ft^3[/tex] or 763 cubic feet.
Step-by-step explanation:
The tank is cylindrical and the volume of a cylinder is given as:
[tex]V = \pi r^2h[/tex]
where r = radius and h = height
The radius, r, of the tank is 4.5 ft and the height, h, of the tank is 12 ft.
Therefore, the volume of the cylindrical water tank is:
[tex]V = \pi * 4.5^2 * 12\\V = 763.407 ft^3[/tex]
Approximating to whole number, the volume of the tank is [tex]763 ft^3[/tex] or 763 cubic feet.

Given the fractions 8/15 and 18/35, find the largest number that these fractions can be divided by, so that the quotient will be a whole number.
Answer:
Therefore the largest number that these fractions can be divided by to give them a whole number is
a) 8/15 = The largest number is 8/15
b) 18/35 = The largest number is 18/35
Step-by-step explanation:
A quotient is the result obtained by dividing two numbers.
So that the quotient obtained is a whole number we have to find out, what number they can be divided by to give them that.
Let's assume the whole number is 1
a. 8/15
8/15 ÷ x = 1
8/15 × 1/x = 1
8/15x = 1
We would cross multiply
8 = 15x
We would divide both sides by 15
8/ 15 = x
Hence the largest number that would divide 8/15 and give it a whole number = 8/15
b) 18/35
18/35÷ x = 1
18/35 × 1/x = 1
18/35x = 1
We would cross multiply
18 = 35x
We would divide both sides by 35
18/ 315 = x
Hence the largest number that would divide 18/35 and give it a whole number = 18/35
Answer:
The answer is 2/105
Step-by-step explanation:
first we have to find the LCM of both denominators. IN this case, the LCM of 15 and 35 is 105. Then we have to find the GCF of these numerators. IN this case, the GCF of 8 and 18 is 2.
Now, put the GCF you found over the LCM.
ANSWER: 2/105
This fraction is the largest number you can divide both numbers by to get a whole number.
