Answer:
Step-by-step explanation:
Kyle has picked 5 1/3 bushels of apples
He want to pick b more bushels of apple to have 9 bushels in all
A) 5[tex]\frac{1}{3}[/tex] + b = 9 bushels
b) b = 9 - 5 [tex]\frac{1}{3}[/tex] = 3 [tex]\frac{2}{3}[/tex]
- Part A: The equation is [tex]\(\frac{16}{3} + b = 9\).[/tex]
- Part B: Kyle needs to pick [tex]\(3 \frac{2}{3}\)[/tex] more bushels of apples.
Let's break down the problem step by step.
Part A: Write an Equation
Kyle has already picked 5 1/3 bushels of apples. He wants to have a total of 9 bushels. We need to find out how many more bushels, b , he needs to pick.
First, convert the mixed number 5 1/3 into an improper fraction:
[tex]\[ 5 \frac{1}{3} = \frac{5 \times 3 + 1}{3} = \frac{15 + 1}{3} = \frac{16}{3} \][/tex]
Now we can write the equation for the total number of bushels he wants:
[tex]\[ \frac{16}{3} + b = 9 \][/tex]
Part B: Solve the Equation
To find b, we solve the equation:
[tex]\[ \frac{16}{3} + b = 9 \][/tex]
Subtract [tex]\(\frac{16}{3}\)[/tex] from both sides of the equation to isolate b :
[tex]\[ b = 9 - \frac{16}{3} \][/tex]
Convert 9 to a fraction with the same denominator as [tex]\(\frac{16}{3}\):[/tex]
[tex]\[ 9 = \frac{9 \times 3}{3} = \frac{27}{3} \][/tex]
Now perform the subtraction:
[tex]\[ b = \frac{27}{3} - \frac{16}{3} = \frac{27 - 16}{3} = \frac{11}{3} \][/tex]
Convert [tex]\(\frac{11}{3}\)[/tex] back to a mixed number if needed:
[tex]\[ \frac{11}{3} = 3 \frac{2}{3} \][/tex]
So, Kyle needs to pick:
[tex]\[ b = 3 \frac{2}{3} \text{ bushels} \][/tex]
Summary
- Part A: The equation is [tex]\(\frac{16}{3} + b = 9\).[/tex]
- Part B: Kyle needs to pick [tex]\(3 \frac{2}{3}\)[/tex] more bushels of apples.
As the SAT is used for college admissions the GRE is used for graduate school admissions. A sample of verbal and
quantitative scores from the GRE are both normally distributed, with the values of H and a are given below.
Verbal Quantitative
670 550
1121 148
Kevin scored 610 on the verbal section and 700 on the quantitative section. Use the standard deviation as a unit of
measurement to comnare Kevin's verhal and quantitative scores on the GRE
Answer:
Step-by-step explanation:
Kevin’s verbal score is 610 is 140 points above the mean,which is 470. the standard deviation is 121 so his verbal score is 140/121≈1.16 standard deviations above the mean. Kevins quantitative score of 700 is 150 points above the mean, which is 500. The standard deviation is 148, so his quantitative score is 150/148 ≈ 1.01 standard deviation above the mean.Thus, Kevins verbal score is better than his quantitative score.

In a box the number of blue counters and the number green counters are in the ratio 7:4. The number of green counters and the number of red counters are in the ratio 3:1. The total number of counters in the bag is 444. How many green counters are in the bag?
Answer:
Number of green counters is 144
Step-by-step explanation:
Please refer to the attached image for explanations
Calculate the total number of parts in the ratio. Determine the total number of green and red counters, which are 4 parts out of a total of 11. Multiply this fraction by the total number of counters (444) to get the total number of green and red counters. The number of green counters is 3 parts out of this total, so a similar multiplication gives the number of green counters.
Explanation:The problem involves the concept of ratios and arithmetic. We need to solve the question in two stages:
Firstly, the question tells us that the number of blue counters and green counters are in the ratio 7:4. This implies, for every 7 blue counters, there are 4 green ones. Therefore, the total number of blue and green counters together can be thought of as 7+4 which equals 11 parts. Secondly, the number of green counters and red counters are in the ratio 3:1. Therefore, the total number of green and red counters together equals 3+1, which is equal to 4 parts. We're given that the total number of green, red, and blue counters is 444. Now, going back to the first step the blue counters are 7 parts out of 11. The green and red counters combined are 4 parts out of 11. So, the total of green and red counters is 4/11 * 444 = 161.04. But since we can't have 0.04 of a counter, it rounds to 161. Now, given that the green counters and red counters are in the ratio 3:1, so out of the total 161, the green counters are 3/4 * 161 = 120.75, which rounds to 121. So there are 121 green counters in the bag.Learn more about Ratios here:

The scale of the drawing was 1 millimeters,2 meters in the drawing, the lawn in the backyard is 28 millimeters long, what is the length of the actual lawn
Answer:
The length of the actual lawn is 56 meters.
Step-by-step explanation:
Given:
The scale of the drawing was 1 millimeters : 2 meters, in the drawing the lawn in the backyard is 28 millimeters long,
Now, to find the length of the actual lawn.
Let the length of the actual lawn be [tex]x.[/tex]
The length of the lawn in the drawing = 28 millimeters.
The scale of the drawing was 1 millimeters : 2 meters.
So, 1 millimeters is equivalent to 2 meters.
Thus, 28 millimeters is equivalent to [tex]x.[/tex]
Now, to get the length of the actual lawn by using cross multiplication method:
[tex]\frac{1}{2} =\frac{28}{x}[/tex]
By cross multiplying we get:
[tex]x=56\ meters.[/tex]
Therefore, the length of the actual lawn is 56 meters.
Huan deposited $850 into a college savings account earning 4.8% interest compounded annually. He also deposited $850 into a second account earning 4.8% simple interest. He made no additional deposits. How much interest does the first account earn in 10 years?
Answer:
$508.41
Step-by-step explanation:
Compound interest is calculated with the formula:
[tex]CI = P(1 + R)^T - P[/tex]
where P = Principal/ Initial amount = $850
R = Rate = 4.8% = 0.048
T = Time elapsed = 10 years
Hence, the compound interest is:
[tex]CI = 850(1 +0.048)^{10} - 850\\\\\\CI = 850(1.048)^{10} - 850\\\\\\CI = (850 * 1.598) - 850\\\\\\CI = 1358.41 - 850\\\\\\[/tex]
CI = $508.41
The interest after the first 10 years is $508.41
The first account with an initial deposit of $850 at a 4.8% interest rate compounded annually will earn approximately $510.87 in interest over 10 years.
The student asked how much interest the first account, which is a college savings account with an initial deposit of $850 at a 4.8% interest rate compounded annually, will earn in 10 years. To calculate this, we can use the formula for compound interest:
A = P(1 + r/n)^nt
Where:
A is the amount of money accumulated after n years, including interest.
P is the principal amount (the initial amount of money).
r is the annual interest rate (decimal).
n is the number of times that interest is compounded per year.
t is the time the money is invested for, in years.
In this case, P = $850, r = 4.8/100 = 0.048, n = 1 (since the interest is compounded annually), and t = 10 years. So, the calculation is:
A = 850(1 + 0.048/1)1*10
A = 850(1 + 0.048)10
A = 850(1.048)10
A ≈ 850(1.60103)
The total amount in the account after 10 years will be approximately $1,360.87.
To find the interest earned, we subtract the original principal from the total amount:
Interest Earned = Total Amount - Original Principal
Interest Earned ≈ $1,360.87 - $850
Interest Earned ≈ $510.87
Therefore, the interest earned in the first account after 10 years is approximately $510.87.

boys : girls: total
4 : 5 : 4+5 =9
To get to a total of 27 we multiply each term by 3
boys : girls: total
4*3 : 5*3 : 9*3
12 :15 :27
There are 12 boys
Final answer:
There are 12 boys in the class of 27 students.
Explanation:
The ratio of boys to girls in the class is 4:5, which means for every 4 boys, there are 5 girls. To find out how many boys there are, if there are 27 students in total, we need to work with this ratio.
Step-by-step Solution:
Determine the total number of parts in the ratio by adding the parts for boys and girls together: 4 parts for boys + 5 parts for girls = 9 parts in total.Divide the total number of students by the total number of parts to find out how many students make up 1 part: 27 students ÷ 9 parts = 3 students per part.Multiply the number of parts for boys by the number of students per part to find the total number of boys: 4 parts × 3 students per part = 12 boys.Therefore, there are 12 boys in the class of 27 students.

A storekeeper wants to mix two types of flour to get 300 pounds, so he can sell it by 2.50$ per pound. If he uses flour worth $2.40 a pound with another flour worth $3.00 a pound, how many pounds of each does he use?
Answer:
90 pounds, 210 pounds
Step-by-step explanation:
Given:
A storekeeper wants to mix two types of flour to get 300 pounds, so he can sell it by 2.50$ per pound.
He uses flour worth $2.40 a pound with another flour worth $3.00 a pound.
Question:
How many pounds of each does he use?
Solution:
Let pounds of one type of flour mixed = [tex]x[/tex]
Then pounds of another type of flour mixed = [tex]300-x[/tex]
Cost of 1 pound of one type of flour = $2.40
Cost of [tex]x[/tex] pounds of one type of flour = [tex]2.4x[/tex]
Similarly,
Cost of 1 pound of another type of flour = $3
Cost of [tex]300-x[/tex] pounds of another type of flour = [tex]3(300-x)=900-3x[/tex]
Cost of mixed flour per pound = $2.5
Total cost of mixed flour per pound = $2.5 [tex]\times[/tex] 300 = $750
Cost of [tex]x[/tex] pounds of one type + Cost of [tex]300-x[/tex] pounds of another type = $750
[tex]2.4x+900-3x=750\\\\ -0.6x+900=750\\ \\ Subtracting\ both\ sides\ by\ 900\\ \\ -0.6x+900-900=750-900\\ \\ -0.6x=-150\\ \\ Minus\ canceled\ by\by\ minus\\ \\ 0.6x=150\\ \\ Dividing\ both\ sides\ by\ 0.6\\ \\ x=90[/tex]
Pounds of one type of flour mixed = [tex]x[/tex] = 90 pounds
Pounds of another type of flour mixed = [tex]300-x[/tex] = 300 - 90 = 210 pounds
Thus, 90 pounds of one and 210 pound of another type of flour mixed.

Pip was thinking of a number. Pip halves the number and gets an answer of 87.2. Form an
equation with x from the information.
Answer:
x/2=87.2
Step-by-step explanation:
Pip was thinking of a number - Let's call this number x
Pip halve the number - So half of x = x/2 (or 1/2 x)
And gets an answer of 87.2 - x/2=87.2
So your equation would be x/2=87.2
I hope this helps :)
Final answer:
Pip's mystery number is found by taking the equation x / 2 = 87.2, where x is the original number. By solving it, we find that x = 174.4.
Explanation:
Pip is thinking of a number. When Pip halves this number, the result is 87.2. To formulate an equation with x based on this information, we consider that halving a number is equivalent to multiplying that number by 0.5 or dividing it by 2.
Therefore, we can represent the situation with the equation x / 2 = 87.2. This equation states that half of Pip's unknown number (x) equals 87.2.
To solve for x, we multiply both sides of the equation by 2:
x = 87.2 × 2
Which simplifies to:
x = 174.4
This means that Pip was thinking of the number 174.4.

(a) what is the probability that a randomly selected bag contains between 11001100 and 14001400 chocolate chips? (b) what is the probability that a randomly selected bag contains fewer than 10001000 chocolate chips? (c) what proportion of bags contains more than 12001200 chocolate chips? (d) what is the percentile rank of a bag that contains 10501050 chocolate chips?
Answer:
a) P ( 1100 < X < 1400 ) = 0.755
b) P ( X < 1000 ) = 0.755
c) proportion ( X > 1200 ) = 65.66%
d) 5.87% percentile
Step-by-step explanation:
Solution:-
- Denote a random variable X: The number of chocolate chip in an 18-ounce bag of chocolate chip cookies.
- The RV is normally distributed with the parameters mean ( u ) and standard deviation ( s ) given:
u = 1252
s = 129
- The RV ( X ) follows normal distribution:
X ~ Norm ( 1252 , 129^2 )
a) what is the probability that a randomly selected bag contains between 1100 and 1400 chocolate chips?
- Compute the standard normal values for the limits of required probability using the following pmf for standard normal:
P ( x1 < X < x2 ) = P ( [ x1 - u ] / s < Z < [ x2 - u ] / s )
- Taking the limits x1 = 1100 and x2 = 1400. The standard normal values are:
P ( 1100 < X < 1400 ) = P ( [ 1100 - 1252 ] / 129 < Z < [ 1400 - 1252 ] / 129 )
= P ( - 1.1783 < Z < 1.14728 )
- Use the standard normal tables to determine the required probability defined by the standard values:
P ( -1.1783 < Z < 1.14728 ) = 0.755
Hence,
P ( 1100 < X < 1400 ) = 0.755 ... Answer
b) what is the probability that a randomly selected bag contains fewer than 1000 chocolate chips?
- Compute the standard normal values for the limits of required probability using the following pmf for standard normal:
P ( X < x2 ) = P ( Z < [ x2 - u ] / s )
- Taking the limit x2 = 1000. The standard normal values are:
P ( X < 1000 ) = P ( Z < [ 1000 - 1252 ] / 129 )
= P ( Z < -1.9535 )
- Use the standard normal tables to determine the required probability defined by the standard values:
P ( Z < -1.9535 ) = 0.0254
Hence,
P ( X < 1000 ) = 0.755 ... Answer
(c) what proportion of bags contains more than 1200 chocolate chips?
- Compute the standard normal values for the limits of required probability using the following pmf for standard normal:
P ( X > x1 ) = P ( Z > [ x1 - u ] / s )
- Taking the limit x1 = 1200. The standard normal values are:
P ( X > 1200 ) = P ( Z > [ 1200 - 1252 ] / 129 )
= P ( Z > 0.4031 )
- Use the standard normal tables to determine the required probability defined by the standard values:
P ( Z > 0.4031 ) = 0.6566
Hence,
proportion of X > 1200 = P ( X > 1200 )*100 = 65.66% ... Answer
d) what is the percentile rank of a bag that contains 1050 chocolate chips?
- The percentile rank is defined by the proportion of chocolate less than the desired value.
- Compute the standard normal values for the limits of required probability using the following pmf for standard normal:
P ( X < x2 ) = P ( Z < [ x2 - u ] / s )
- Taking the limit x2 = 1050. The standard normal values are:
P ( X < 1050 ) = P ( Z < [ 1050 - 1252 ] / 129 )
= P ( Z < 1.5659 )
- Use the standard normal tables to determine the required probability defined by the standard values:
P ( Z < 1.5659 ) = 0.0587
Hence,
Rank = proportion of X < 1050 = P ( X < 1050 )*100
= 0.0587*100 %
= 5.87 % ... Answer

The point (2,6) is on the line given by which equation below?
Answer:
A y = 3x
Step-by-step explanation:
We can check each line to see if the point is on it
A y = 3x 6 = 2*3 6=6 this is true so the point is one the line
B y = 4-x 6 = 2-4 6 = -2 false
C y = -3x 6 = -3(2) 6=-6 false
D y =-x+4 6 = -2+4 6 = 2 false
If cos 0 = 0.3846 where 3pi/2 is less than 0 is less than 2pi, what is the approximate value of sin 0?
Answer:
-0.9231
Step-by-step explanation:
Given cos theta = 0.3846 within the range 3π/2<theta<2π
Costheta = 0.3846
Theta = arccos(0.3846)
Theta = 67.38°
Since 67.38° didn't fall within the range of theta, we will locate our theta using the quadrant.
Since cos is positive in the 4th quadrant,
Theta = 360-67.38°
Theta = 292.62°
Sin(theta) = sin(292.62°)
= -0.9231
